Little Known Apache Mesos Project Helps Mesosphere Raise $10M From Andreessen Horowitz
================================================================================

[Mesosphere][1], the company trying to build a business around the little-known open source [Apache Mesos][2] project, just racked up a $10 million investment from Andreessen Horowitz. Here’s why it attracted that kind of cash.
Mesos, software for automatic scaling, was in fact built around five years ago and is already in use on more than 50,000 cores at Twitter, according to Florian Leibert, CEO and co-founder of Mesosphere. EBay, AirBnB, Netflix and HubSpot are also fans.
While those big Web companies have discovered Mesos, the technology isn’t widely known among enterprises. But it could fill a need for companies which are trying to adopt some of the techniques available to them in public clouds on their internal data centers.
Mesos manages clusters of machines, automatically scaling apps as needed. It requires a small bit of software on each machine – the software uses zero processing power and “negligible” memory, according to Liebert — which coordinates with a master scheduler. The software on each machine reports information about the capacity of the virtual machine or bare metal server to the scheduler, which allocates jobs to available machines.
“If a task goes down and it doesn’t report back, the master knows to reschedule it and knows where it has resources,” said Matt Trifiro, senior vice president at Mesosphere.
Mesos can automatically scale a variety of jobs including Hadoop databases, nodes running Ruby on Rails, and Cassandra.
Using Mesos, Hubspot slashed its Amazon Web Services bill in half, said Liebert. That’s because Mesos efficiently assigns workloads to available machines.
However, Mesos might be most appealing to businesses that are trying to essentially create an AWS-like environment internally, said Jay Lyman, an analyst at 451 Research. AWS offers some [tools for automatic scaling][3]. But many businesses are still shy about running everything on public cloud infrastructure. At the same time, they don’t want to block their developers from taking advantage of the capabilities available in public clouds like AWS. They’d like to make those capabilities available on their private clouds.
“You’re seeing the interface of AWS-style strategy meets the old guard and command and control and stability,” he said.
Mesos can run in both a private cloud and AWS, offering businesses the opportunity to most efficiently use their internal cloud and fallover to AWS when they need to scale.
Mesos has some shortcomings in that regard, however. It [doesn’t run][4] any Windows or legacy apps like SAP, for instance.
However, “if a team is contemplating cloud, they’re probably pretty deep into Linux already,” said Lyman.
In the future, it’s possible Mesosphere could support Windows. Initially, technologies like Puppet and Chef only supported Linux too, Lyman noted. “It speaks to the early nature of Mesosphere. It’s pretty immature right now,” he said.
Mesosphere is targeting the many enterprises that are building more and more apps running on Linux and modern programming languages as well as the first generation Web 2.0 companies like Twitter and Netflix that didn’t have technology like Mesos when they first launched. “Those are the two most common early adopter profiles,” Trifiro said.
Before the end of the year, Mesosphere hopes to release commercial products with documentation, earning revenue from support and licensing. It has built a large-scale orchestration tool called Marathon and supports Docker integration. It’s currently offering packaged Mesos distributions for free in hopes of seeding the market.
Mesosphere is also currently working with a handful of early customers. It helped HubSpot get going with its use of Mesos.
Mesosphere isn’t alone in going after this use case. Rightscale, Scalr and Enstratius, now owned by Dell, all offer some version of scaling or cloud management technology. Mesosphere argues that Mesos, and the company’s own technologies, go above and beyond what’s on the market to create server clusters that essentially operate as one machine. The new investment from Andreessen could help it gain momentum.

有人知道 Apache Mesos 项目帮助 Mesosphere 公司从 Andreessen Horowitz 那里筹集了 1000 万美元吗？
================================================================================
![](http://thenewstack.io/wp-content/uploads/2014/04/clouds.jpg)
[Mesosphere][1]，一家试图以鲜为人知的 Apache Mesos 项目为中心开展商业活动的公司，刚刚从 Andreessen Horowitz 那里获得了 1000 万美元投资。以下是为什么这个项目能够吸引如此巨款的原因。
事实上 Mesos 这款自动扩放软件在五年前就开发出来了。据 Mesosphere 的首席执行官及联合创始人 Florian Leibert 所述，Mesos 已经在 Twitter 上被超过 50,000 的核心使用。同时 EBay, AirBnB, Netflix 还有 HubSpot 也是这款软件的使用者。
当那些互联网巨头发现发现 Mesos 的时候，这项技术却并不为大多数企业所知。但它确实可以满足一些公司试图在公共云采取技术措施，使得他们自己可以访问内部数据中心的需求。
Mesos 管理集群机器，根据需要自动扩放应用。它在每台机器上只依赖很少的软件 ———— 据 Leibert 所说，其处理器的占用为 0 并且几乎不消耗任何内存 ———— 会与一个主调度程序相协调。在其工作的每台机器上的该软件会向调度程序报告关于虚拟机或者服务器的容量信息，接着调度程序向目标机器分派任务。
“如果一项任务终断并且没有返回任何结果，在 Mesos 的协助下，管理员将重启该任务并能知道该任务在何处终断，” Mesosphere 的资深副总裁 Matt Trifiro 说。
Mesos 能自动扩放一系列的工作包括 Hadoop 数据库，Ruby 运行干线上的节点，以及 Cassandra 。
使用 Mesos 使得 Hubspot 在 AWS(Amazon Web Services) 的账单上削减了一半的支出，Liebert 说道。这是因为 Mesos 能够在目标机器之间有效地分配作业量的原因。
然而，Mesos 更有可能应用于企业中去，这些企业试图实质地内部创建一个类 AWS 环境，一位来自 451 Research 的分析员 Jay Lyman 说。AWS 提供一些[自动扩放工具][3]。但大多数公司对于在公共云基础设施上运行所有东西还是感到不安。与此同时，他们并不企图阻止他们的开发者采用 AWS 那样的公共云中可用的优异性能。他们希望他们的私有云能集成这些可用的优点。
“如你所见，AWS 风格的界面风格与守旧主义、命令、操控以及稳定性相融合，” Liebert 继续说道。
Mesos 既可以在一个私有云上也可以在 AWS 上运行，向企业提供最有效率地使用其内部云的方法，并在需要扩放时自动切换到 AWS 去。
但是，以某种角度观察 Mesos 也是有一些缺点的。它[并不能运行][4]任何 Windows 操作系统或者比较古老的应用比如说 SAP 软件。
不过，Lyman 说，“假如一个团队拥有长时期使用云的经历，他们大概早就对 Linux 操作系统情有独钟了。”
在将来，Mesosphere 能够支持 Windows 操作系统是很有可能的。最初，像 Puppet 和 Chef 这样的技术也只支持 Linux 操作系统，Lyman 表示。“这预示了早期 Mesosphere 的特性。现在它还是不太成熟，” 他又说道。
Mesosphere 正瞄向大部分构建了与日俱增的运行于 Linux 操作系统的应用的企业，以及使用现代编程语言如同 Twitter 和 Netflix 这类刚成立不久还未具备 Mesos 这种技术的初代 Web 2.0 公司。“这是早期两类最常见的客户概况，” Trifiro 说。
年终之前，Mesosphere 希望发布包含文档的商务产品，通过技术支持与颁发许可证来获得收入。Mesosphere 已开发一款名为 Marathon 的大规模扩放编制工具，并且支持融入 Docker 中。它现在免费提供打包过的 Mesos 分发，希望以此占有未来的市场。
Mesosphere 同时也正在为少数早期的顾客工作。它帮助 HubSpot 实施有关 Mesos 的搭建。
Mesosphere 在这个领域并不唯一。Rightscale，Scalr 以及现在归 Dell 所有的 Enstratius，全都提供了一些扩放或云管理技术的版本实例。Mesosphere 强调说其开发的技术 Mesos 在单独机器中创建服务器集群方面的表现远胜于市场上的其他同类软件。来自 Andreessen 的新投资一定会帮助 Meos 获得新生。
