New machine learning from Alibaba and Netflix, mimicking animal vision, and more open source news
======
Catch up on the biggest open source headlines from the past two weeks.
![Weekly news roundup with TV][1]
In this edition of our open source news roundup, we take a look an open source election auditing tool, new open source from Alibaba and Netflix, mimicking animal vision, and more!
### Alibaba and Netflix share machine learning and data science software
Two companies at the forefront of machine learning and data science have just released some of their tools under open source licenses.
Chinese ecommerce giant Alibaba just [open sourced the algorithm libraries][2] for its Alink platform. The algorithms "are essential to support machine learning tasks such as online product recommendations and smart customer services." According to Jia Yangqing, president of Alibaba Cloud, Alink is a good fit for "developers seeking big data and machine-learning tools." You can find the source code for Alink (which is under an Apache 2.0 license) [on GitHub][3], with documentation in both Chinese and English.
Not to be outdone, streaming service Netflix just released its [Metaflow Python library][4] under an Apache 2.0 license. Metaflow enables data scientists to "see early on whether a prototyped model would fail in production, allowing them to fix whatever the issue was". It also works with a number of Python data science libraries, like SciKit Learn, Pytorch, and Tensorflow. You can grab Metaflow's code from [its GitHub repository][5] or learn more about it at the [Metaflow website][6].
### Open source software to mimic animal vision
Have you ever wondered how your dog or cat sees the world? Thanks to work by researchers at the University of Exeter in the UK and Australia's University of Queensland, you can find out. The team just released [software that allows humans to see the world as animals do][7].
Called micaToolbox, the software can interpret digital photos and process images of various environments by mimicking the limitations of animal vision. Anyone with a camera, a computer, or smartphone can use the software without knowing how to code. But micaToolbox isn't just a novelty. It's a serious scientific tool that can help "help biologists better understand a variety of animal behaviors, including mating systems, distance-dependent signalling and mimicry." And, according to researcher Jolyon Troscianko, the software can help identify "how an animal's camouflage works so that we can manage our land to protect certain species."
You can [download micaBox][8] or [browse its source code][9] on GitHub.
### New tool for post-election auditing
More and more aspects of our lives and institutions are being automated. With that comes an increased danger of systems breaking down or malicious someones tampering with those systems. Open source gives us an opportunity to look at exactly how the automation works.
Elections, in particular, are increasingly vulnerable. To combat election tampering, the US Cybersecurity and Infrastructure Security Agency (CISA) has joined forces with the non-profit organization VotingWorks to create a [web-based application for auditing ballots][10].
Called Arlo, the application is designed to ensure that "elections are secure, resilient, and transparent," said CISA's director Chris Krebs. Arlo works with a range of automated voting systems to help "officials compare audited votes to tabulated votes, and providing monitoring & reporting capabilities." Arlo was used to verify the results of recent state and local elections and is being further field-tested in the states of Georgia, Michigan, Missouri, Ohio, Pennsylvania, and Virginia.
Arlo's source code, released under an AGPL-3.0 license, is [available on GitHub][11].
### Royal Navy debuts open source application development kit
Consistency across user interfaces is key to a successful set of applications and services. The UK's Royal Navy understands the importance of this and has released the [open source NELSON standards toolkit][12] to help its developers and suppliers "save time and give users a consistent experience."
Named after the legendary British admiral, NELSON is intended to "maintain high visual consistency and user-experience quality across the different applications developed or subcontracted by the Royal Navy." The toolkit consists of a set of components including visual styles, typographic elements, forms, elements like buttons and checkboxes, and notifications.
NELSON has its own [GitHub repository][13], from which the Royal Navy encourages developers to make pull requests.

[#]: via: (https://itsfoss.com/ubuntu-cinnamon/)

First Ever Release of Ubuntu Cinnamon Distribution is Finally Here!
======
_**Brief: Ubuntu Cinnamon is a new distribution that utilizes Linux Mints Cinnamon desktop environment on top of Ubuntu code base. Its first stable release is based on Ubuntu 19.10 Eoan Ermine.**_
[Cinnamon][1] is Linux Mints flagship desktop environment. Like [MATE desktop][2], Cinnamon is also a product of dissatisfaction with GNOME 3. With the GNOME Classic like user interface and relatively lower hardware requirements, Cinnamon soon gathered a dedicated userbase.
Like any other desktop environment out there, you can [install Cinnamon on Ubuntu][3] and other distributions.
Installing multiple [desktop environments][4] (DE) is not a difficult task but it often leads to conflicts (with other DEs elements) and may not always provide the best experience. This is why major Linux distributions separate spins/flavors with various popular desktop environments.
[Ubuntu also has various official flavors][5] featuring [KDE][6] (Kubuntu), [LXQt][7] (Lubuntu), Xfce (Xubuntu), Budgie ([Ubuntu Budgie][8]) etc. Cinnamon was not in this list but Ubuntu Cinnamon Remix project is trying to change that.
### Ubuntu Cinnamon distribution
![Ubuntu Cinnamon Desktop Screenshot][9]
[Ubuntu Cinnamon][10] (website under construction) is a new Linux distribution that brings Cinnamon desktop to Ubuntu distribution. Joshua Peisach is the lead developer for the project and he is being helped by other volunteer contributors. The ex-developer of the now discontinued Ubuntu GNOME project and some members from Ubuntu team are also advising the team to help with the development.
![Ubuntu Cinnamon Remix Screeenshot 1][11]
Do note that Ubuntu Cinnamon is not an official flavor of Ubuntu. They are trying to get the flavorship but I think that will take a few more releases.
The first stable release of Ubuntu Cinnamon is based on [Ubuntu 19.10 Eoan Ermine][12]. It uses Calamares installer from Lubuntu and features Cinnamon desktop version 4.0.10. Naturally, it uses Nemo file manager and LightDM.
It supports EFI and UEFI and only comes with 64-bit support.
Youll get your regular goodies like LibreOffice, Firefox and some GNOME software and games. You can of course install more applications as per your need.
### Download and install Ubuntu Cinnamon
Do note that this is the first ever release of Ubuntu Cinnamon and the developers are not that experienced at this moment.
If you dont like troubleshooting, dont use it on your main system. I expect this release to have a few bugs and issues which will be fixed eventually as more users test it out.
You can download Ubuntu Cinnamon ISO from Sourceforge website:
[Download Ubuntu Cinnamon][13]
### What next from here?
The dev team has a few improvements planned for the 20.04 release. The changes are mostly on the cosmetics though. There will be new GRUB and Plymouth theme, layout application and welcome screen.
I downloaded it and tried it in a live session. Heres what this distribution looks like:

Meanwhile, if you manage to try it on your own, why not share your experience in the comments? If you use Linux Mint, will you switch to Ubuntu Cinnamon in near future? What are your overall opinion about this new project? Do share it in the comment section.

KubeCon gets bigger, the kernel gets better, and more industry trends
======
A weekly look at open source community, market, and industry trends.
![Person standing in front of a giant computer screen with numbers, data][1]
As part of my role as a senior product marketing manager at an enterprise software company with an open source development model, I publish a regular update about open source community, market, and industry trends for product marketers, managers, and other influencers. Here are five of my and their favorite articles from that update.
## [KubeCon showed Kubernetes is big, but is it a Unicorn?][2]
> Its hard to remember now but there was a time when Kubernetes was a distant No. 3 in terms of container orchestrators being used in the market. Its also eye opening to now realize that [the firms][3] that hatched the two platforms that [towered over][4] Kubernetes have had to completely re-jigger their business models under the Kubernetes onslaught.
>
> And full credit to the CNCF for attempting to diffuse some of that attention from Kubernetes by spending the vast majority of the KubeCon opening keynote address touting some of the nearly two dozen graduated, incubating, and sandbox projects it also hosts. But, it was really the Big K that stole the show.
**The impact:** Open source is way more than the source code; governance is a big deal and can be the difference between longevity and irrelevance. Gathering, organizing, and maintaining humans is an entirely different skill set than doing the same for bits, but can have just as big an influence on the success of a project.
## [Report: Kubernetes use on the rise][5]
> At the same time, the Datadog report notes that container churn rates are approximately 10 times higher in orchestrated environments. Churn rates in container environments that lack an orchestration platform such as Kubernetes have increased in the last year as well. The average container lifespan at a typical company running infrastructure without orchestration is about two days, down from about six days in mid-2018. In 19% of those environments not running orchestration, the average container lifetime exceeded 30 days. That compares to only 3% of organizations running containers longer than 30 days in Kubernetes environments, according to the reports findings.
**The impact**: If your containers aren't churning, you're probably not getting the full benefit of the technology you've adopted.
## [Upcoming Linux 5.5 kernel improves live patching, scheduling][6]
> A new WFX Wi-Fi driver for the Silicon Labs WF200 ASIC transceiver is coming to Linux kernel 5.5. This particular wireless transceiver is geared toward low-power IoT devices and uses a 2.4 GHz 802.11b/g/n radio optimized for low power RF performance in crowded RF environments. This new driver can interface via both Serial Peripheral Interface (SPI) and Secure Digital Input Output (SDIO).
**The impact**: The kernel's continued relevance is a direct result of the never-ending grind to keep being where people need it to be (i.e. basically everywhere).
## [DigitalOcean Currents: December 2019][7]
> In that spirit, this falls installment of our seasonal Currents report is dedicated to open source for the second year running. We surveyed more than 5800 developers around the world on the overall health and direction of the open source community. When we last checked in with the community in [2018][8], more than half of developers reported contributing to open source projects, and most felt the community was healthy and growing.
**The impact**: While the good news outweighs the bad, there are a couple of things to keep an eye on: namely, making open source more inclusive and mitigating potential negative impact of big money.
_I hope you enjoyed this list of what stood out to me from last week and come back next Monday for more open source community, market, and industry trends._

Annual release cycle for Python, new Python Software Foundation fellows from Africa, and more updates
======
Find out what's going on in the Python community in December.
![Python in a coffee cup.][1]
The Python Software Foundation (PSF) is a nonprofit organization behind the Python programming language. I am fortunate to be a PSF Fellow (honorable member for life,) a Python core developer, and the liaison between my company, Red Hat, and the PSF. Part of that liaison work is providing updates on whats happening in the Python community. Heres a look at what we have going on in December.
### Upcoming events
A significant part of the Python community is its in-person events. These events are where users and contributors intermingle and learn together. Here are the big announcements of upcoming opportunities to connect.
#### PyCon US 2020
[PyCon US][2] is by far the largest annual Python event. The next PyCon is April 15-23, 2020, in Pittsburgh. The call for proposals is open to all until December 20, 2019. Im planning to attend PyCon for the conference and its [famous post-con sprints][3].
#### EuroPython
EuroPython is the largest Python conference in Europe with about 1,000 attendees in the last years. [EP20][4] will be held in Dublin, Ireland, July 20-26, 2020. As a liaison for Red Hat, Im proud to say that Red Hat sponsored EP18 in Edinburgh and donated the sponsoring tickets to Women Who Code Scotland.
#### PyData
[PyData][5] is a separate nonprofit related to the Python community through a focus on data science. They host many international events throughout the year, with upcoming events in [Austin, Texas][6], and [Warsaw, Poland][7] before the end of the year.
### New PSF fellows from Africa
The PSF promotes a few members to fellow every quarter. Yesterday, twelve new PSF fellows were [announced][8].
Id like to highlight the four new fellows from Ghana, who are also the organizers of the first pan-African [PyCon Africa][9], which took place in August 2019 in Accra, Ghana. The Python community in Africa is growing at an amazing speed. PyCon Africa 2020 will be in Accra again, and Im planning to spend my summer vacation there.
### Annual release cycle for Python
Python used to release a new major version about every 18 months. This timeline will change with the Python 3.9 release. With [PEP 602,][10] a new major version of Python will be released annually in October. The new cadence means fewer changes between releases and more predictable release dates. October was chosen to align with Linux distribution releases such as Fedora. Miro Hrončok from the Python maintenance team joined the discussion and has helped to find a convenient release date for us; for more details, please see <https://discuss.python.org/t/pep-602-annual-release-cycle-for-python/2296/79?u=ambv>.
### Steering council election
The Python Steering Council governs the development of Python. It was established after [Guido van Rossum stepped down][11] as benevolent dictator for life. Python core developers elect a new steering council for every major Python release. For the upcoming term, nine candidates were nominated for five seats on the council (with Guido being nominated, but [withdrawing][12]). See <https://www.python.org/dev/peps/pep-8101/> for all the details. Election results are expected to be announced mid-December.
That covers whats new in the Python community for December. Stay tuned for more updates in the future and mark your calendars for the conferences mentioned above.
So you have a great business idea for a wonderful IT product or service, and you want to build your...

2020 technology must haves, a guide to Kubernetes etcd, and more industry trends
======
A weekly look at open source community, market, and industry trends.
![Person standing in front of a giant computer screen with numbers, data][1]
As part of my role as a senior product marketing manager at an enterprise software company with an open source development model, I publish a regular update about open source community, market, and industry trends for product marketers, managers, and other influencers. Here are five of my and their favorite articles from that update.
## [Gartner's top 10 infrastructure and operations trends for 2020][2]
> “The vast majority of organisations that do not adopt a shared self-service platform approach will find that their DevOps initiatives simply do not scale,” said Winser. "Adopting a shared platform approach enables product teams to draw from an I&amp;O digital toolbox of possibilities, while benefiting from high standards of governance and efficiency needed for scale."
**The impact**: The breakneck change of technology development and adoption will not slow down next year, as the things you've been reading about for the last two years become things you have to figure out to deal with every day.
## [A guide to Kubernetes etcd: All you need to know to set up etcd clusters][3]
> Etcd is a distributed reliable key-value store which is simple, fast and secure. It acts like a backend service discovery and database, runs on different servers in Kubernetes clusters at the same time to monitor changes in clusters and to store state/configuration data that should to be accessed by a Kubernetes master or clusters. Additionally, etcd allows Kubernetes master to support discovery service so that deployed application can declare their availability for inclusion in service.
**The impact**: This is actually way more than I needed to know about setting up etcd clusters, but now I have a mental model of what that could look like, and you can too.
## [How the open source model could fuel the future of digital marketing][4]
> In other words, the broad adoption of open source culture has the power to completely invert the traditional marketing funnel. In the future, prospective customers could be first introduced to “late funnel” materials and then buy into the broader narrative — a complete reversal of how traditional marketing approaches decision-makers today.
**The impact**: The SEO on this cuts two ways: It can introduce uninitiated marketing people to open source and uninitiated technical people to the ways that technology actually gets adopted. Neat!
## [Kubernetes integrates interoperability, storage, waits on sidecars][5]
> In a [recent interview][6], Lachlan Evenson, and was also a lead on the Kubernetes 1.16 release, said sidecar containers was one of the features that team was a “little disappointed” it could not include in their release.
>
> Guinevere Saenger, software engineer at GitHub and lead for the 1.17 release team, explained that sidecar containers gained increased focus “about a month ago,” and that its implementation “changes the pod spec, so this is a change that affects a lot of areas and needs to be handled with care.” She noted that it did move closer to completion and “will again be prioritized for 1.18.”
**The impact**: You can read between the lines to understand a lot more about the Kubernetes sausage-making process. It's got governance, tradeoffs, themes, and timeframes; all the stuff that is often invisible to consumers of a project.
_I hope you enjoyed this list of what stood out to me from last week and come back next Monday for more open source community, market, and industry trends._

_**Linux Mint 19.3 “Tricia” has been released. See whats new in it and learn how to upgrade to Linux Mint 19.3.**_
The Linux Mint team finally announced the release of Linux Mint 19.3 codenamed Tricia with useful feature additions along with a ton of improvements under-the-hood.
This is a point release based on the latest **Ubuntu 18.04.3** and it comes packed with the **Linux kernel 5.0**.
I downloaded and quickly tested the edition featuring the [Cinnamon 4.4][1] desktop environment. You may also try the Xfce or MATE edition of Linux Mint 19.3.
### Linux Mint 19.3: Whats New?
![Linux Mint 19 3 Desktop][2]
While being an LTS release that will be supported until 2023 it brings in a couple of useful features and improvements. Let me highlight some of them for you.
#### System Reports
![][3]
Right after installing Linux Mint 19.3 (or upgrading it), you will notice a warning icon on the right side of the panel (taskbar).
When you click on it, you should be displayed a list of potential issues that you can take care of to ensure the best out of Linux Mint experience.
For starters, it will suggest that you should create a root password, install a language pack, or update software packages in the form of a warning. This is particularly useful to make sure that you perform important actions even after following the first set of steps on the welcome screen.
#### Improved Language Settings
Along with the ability to install/set a language, you will also get the ability to change the time format.
So, the language settings are now more useful than ever before.
#### HiDPI Support
As a result of [HiDPI][4] support, the system tray icons will look crisp and overall, you should get a pleasant user experience on a high-res display.
#### New Applications
![Linux Mint Drawing App][5]
With the new release, you will n longer find “**GIMP**” pre-installed.
Even though GIMP is a powerful utility, they decided to add a simpler “**Drawing**” app to let users to easily crop/resize images while being able to tweak it a little.
Also, **Gnote** replaces **Tomboy** as the default note-taking application on Linux Mint 19.3
In addition to both these replacements, Celluloid video player has also been added instead of Xplayer. In case you did not know, Celluloid happens to be one of the [best open source video players][6] for Linux.
#### Cinnamon 4.4 Desktop
![Cinnamon 4 4 Desktop][7]
In my case, the new Cinnamon 4.4 desktop experience introduces a couple of new abilities like adjusting/tweaking the panel zones individually as you can see in the screenshot above.
#### Other Improvements
There are several other improvements including more customizability options in the file manager and so on.
You can read more about the detailed changes in the [official release notes][8].

### Linux Mint 19 vs 19.1 vs 19.2 vs 19.3: Whats the difference?
You probably already know that Linux Mint releases are based on Ubuntu long term support releases. Linux Mint 19 series is based on Ubuntu 18.04 LTS.
Ubuntu LTS releases get point releases on the interval of a few months. Point release basically consists of bug fixes and security updates that have been pushed since the last release of the LTS version. This is similar to the Service Pack concept in Windows XP if you remember it.
If you are going to download Ubuntu 18.04 which was released in April 2018 in 2019, youll get Ubuntu 18.04.2. The ISO image of 18.04.2 will consist of 18.04 and the bug fixes and security updates applied till 18.04.2. Imagine if there were no point releases, then right after [installing Ubuntu 18.04][10], youll have to install a few gigabytes of system updates. Not very convenient, right?
But Linux Mint has it slightly different. Linux Mint has a major release based on Ubuntu LTS release and then it has three minor releases based on Ubuntu LTS point releases.
Mint 19 was based on Ubuntu 18.04, 19.1 was based on 18.04.1 and Mint 19.2 is based on Ubuntu 18.04.2. Similarly, Mint 19.3 is based on Ubuntu 18.04.3. It is worth noting that all Mint 19.x releases are long term support releases and will get security updates till 2023.
Now, if you are using Ubuntu 18.04 and keep your system updated, youll automatically get updated to 18.04.1, 18.04.2 etc. Thats not the case in Linux Mint.
Linux Mint minor releases also consist of _feature changes_ along with bug fixes and security updates and this is the reason why updating Linux Mint 19 wont automatically put you on 19.1.
Linux Mint gives you the option if you want the new features or not. For example, Mint 19.3 has Cinnamon 4.4 and several other visual changes. If you are happy with the existing features, you can stay on Mint 19.2. Youll still get the necessary security and maintenance updates on Mint 19.2 till 2023.
Now that you understand the concept of minor releases and want the latest minor release, lets see how to upgrade to Mint 19.3.
### Linux Mint 19.3: How to Upgrade?
No matter whether you have Linux Mint 19.1 or 19, you can follow these steps to [upgrade Linux Mint version][11].
**Note**: _You should consider making a system snapshot (just in case) for backup. In addition, the Linux Mint team advises you to disable the screensaver and upgrade Cinnamon spices (if installed) from the System settings._
![][12]
1. Launch the Update Manager.
2. Now, refresh it to load up the latest available updates (or you can change the mirror if you want).
3. Once done, simply click on the Edit button to find “**Upgrade to Linux Mint 19.3 Tricia**” button similar to the image above.
4. Finally, just follow the on-screen instructions to easily update it.
Based on your internet connection, it should take anything between a couple of minutes to 30 minutes.
### Dont see Mint 19.3 update yet? Heres what you can do
If you dont see the option to upgrade to Linux Mint 19.3 Tricia, dont lose hope. Here are a couple of things you can do.
#### **Step 1: Make sure to use mint-upgrade-info version 1.1.3**
Make sure that mint-upgrade-info is updated to version 1.1.3. You can try the install command that will update it to a newer version (if there is any).
```
sudo apt install mint-upgrade-info
```
#### **Step 2: Switch to default software sources**
Chances are that you are using a mirror closer to you to get faster software downloads. But this could cause a problem as the mirrors might not have the new upgrade info yet.
Go to Software Source and change the sources to default. Now run the update manager again and see if Mint 19.3 upgrade is available.
### Download Linux Mint 19.3 Tricia
If you want to perform a fresh install, you can easily download the latest available version from the official download page (depending on what edition you want).
You will also find multiple mirrors available to download the ISOs feel free to try the nearest mirror for potentially faster download.

Eliminating gender bias in open source software development, a database of microbes, and more open source news
======
Catch up on the biggest open source headlines from the past two weeks.
![Weekly news roundup with TV][1]
In this edition of our open source news roundup, we take a look at eliminating gender bias in open source software development, an open source database of microbes, an open source index for cooperatives, and more!
### Eliminating gender bias from open source development
It's a sad fact that certain groups, among them women, are woefully underrepresented in open source projects. It's like a bug in the open source development process. Fortunately, there are initiatives to make that under representation a thing of the past. A study out of Oregon State University (OSU) intends to resolve the issue of the lack of women in open source development by "[finding these bugs and proposing redesigns around them][2], leading to more gender-inclusive tools used by software developers."
The study will look at tools commonly used in open source development — including Eclipse, GitHub, and Hudson — to determine if they "significantly discourage newcomers, especially women, from joining OSS projects." According to Igor Steinmacher, one of the principal investigators of the study, the study will examine "how people use tools because the 'bugs' may be embedded in how the tool was designed, which may place people with different cognitive styles at a disadvantage."
The developers of the tools being studied will walk through their software and answer questions based on specific personas. The researchers at OSU will suggest ways to redesign the software to eliminate gender bias and will "create a list of best practices for fixing gender-bias bugs in both products and processes."
### Canadian university compiles open source microbial database
What do you do when you have a vast amount of data but no way to effectively search and build upon it? You turn it into a database, of course. That's what researchers at Simon Fraser University in British Columbia, along with collaborators from around the globe, did with [information about chemical compounds created by bacteria and fungi][3]. Called the Natural Products Atlas, the database "holds information on nearly 25,000 natural compounds and serves as a knowledge base and repository for the global scientific community."
Licensed under a Creative Commons Attribution 4.0 International License, the Natural Products Atlas "holds information on nearly 25,000 natural compounds and serves as a knowledge base and repository for the global scientific community." The [website for the Natural Products Atlas][4] hosts the database also includes a number of visualization tools and is fully searchable.
Roger Linington, an associate professor at SFU who spearheaded the creation of the database, said that having "all the available data in one place and in a standardized format means we can now index natural compounds for anyone to freely access and learn more about."
### Open source index for cooperatives
Europe has long been a hotbed of both open source development and open source adoption. While European governments strongly advocate open source, non profits have been following suit. One of those is Cooperatives Europe, which is developing "[open source software to allow users to index co-op information and resources in a standardised way][5]."
The idea behind the software, called Coop Starter, reinforces the [essential freedoms of free software][6]: it's intended to provide "education, training and information. The software may be used and repurposed by the public for their own needs and on their own infrastructure." Anyone can use it "to reference existing material on co-operative entrepreneurship" and can contribute "by sharing resources and information."
The [code for Coop Starter][7], along with a related WordPress plugin, is available from Cooperative Europe's GitLab repository.

Its the end for Windows Server 2008 support
======
Microsoft recommends migrating Server 2008 workloads to Azure cloud services while enterprises modernize their apps for Windows Server 2016 or 2019 deployments.

This week's Patch Tuesday marked the end of the line for both Windows 7 and Windows Server 2008 (and 2008 R2). No more fixes will be issued for the two aged operating systems, unless you purchase a pricey extended service license.
On the Windows 7 front, Microsoft has done a good job getting Windows 10 deployed through its aggressive (perhaps too aggressive) upgrade program. According to StatCounter, Windows 10 now accounts for 65% of the [worldwide desktop Windows market share][1], and Windows 7 is down to 27%.
**RELATED:** [What to know before upgrading to Windows Server 2019][2]
But while Windows 7 has gotten all the attention, Server 2008 actually has a larger share of holdouts, and in some ways, its end-of-life milestone is more significant. At last Julys Inspire show, a Microsoft executive said in an interview with cloud storage provider and Microsoft partner Carbonite that [60% of its current Windows Server][3] installed base was running Server 2008, accounting for 24 million instances.

Combine the agility and economics of HPE storage with HPE GreenLake and run your IT department with efficiency.
“There are a lot [of customers sticking with Server 2008],” says analyst Tim Crawford of research and advisory firm [AVOA][5]. “You could categorize them into those that either a) use functions specific to WS2008, and b) those that use a version of an application that is only compatible with WS2008. Upgrading is often easier said than done. Especially if the application is a custom app with lots of tentacles.”
Server 2008 is based on the Windows Vista codebase, which should be reason alone to jettison it. But Windows Server 2016 and Windows Server 2019 are built on Windows 10, which means apps heavily dependent on the OS ecosystem might be hard to move since the internals are so different.
“I do work with folks that are still running Windows Server 2008. They understand the ramifications of EOL for support. But most are in a predicament where they arent able to move the applications for a number of reasons, including application compatibility, location, etc.," Crawford says.
For those apps that are challenging to move, he recommends isolating the system as much as possible to protect it, and putting in a plan to do what is needed to the applications to prepare them for movement as quickly as possible.
Microsoft offers and recommends [Azure migration][6], so Server 2008 apps can [run in an Azure instance][7] while they are modernized for Server 2019 and then deployed on premises.
Migration should be the paramount effort, because if you are running Server 2008 then you're using hardware that's at least eight years old and potentially 12 years old. Thats ancient in technology terms, and if nothing else, the hardware is going to fail.
One of the headaches for admins is you cannot migrate Server 2008 directly to 2016 or 2019. You have to upgrade to Server 2012 as an intermediate step. So you are better off biting the bullet and migrating the apps to 2019 rather than spending time on two OS migrations.
Microsoft has provided [resources][8] for Server 2008 users, including a migration guide and help moving to Azure.
