Build, Deploy and Manage Custom Apps with IBM Bluemix
|
||||
============================================================
|
||||
|
||||
|
||||
|
||||
|
||||
_IBM’s Bluemix affords developers an opportunity to build, deploy and manage custom apps. Bluemix is built on Cloud Foundry. It supports a number of programming languages as well as OpenWhisk, which allows developers to call any function without the need for resource management._
|
||||
|
||||
Bluemix is an open standards, cloud-based platform implemented by IBM. It has an open architecture which enables organisations to create, develop and manage their applications on the cloud. It is based on Cloud Foundry and hence can be considered as a Platform as a Service (PaaS). With Bluemix, developers need not worry about cloud configurations, but can concentrate on their applications. Cloud configurations will be done automatically by Bluemix.
|
||||
|
||||
Bluemix also provides a dashboard, with which developers can create, manage and view services and applications, while monitoring resource usage also.
|
||||
It supports the following programming languages:
|
||||
|
||||
* Java
|
||||
* Python
|
||||
* Ruby on Rails
|
||||
* PHP
|
||||
* Node.js
|
||||
|
||||
It also supports OpenWhisk (Function as a Service), which is also an IBM product that allows developers to call any function without requiring any resource management.

**How IBM Bluemix works**
|
||||
Bluemix is built on top of IBM’s SoftLayer IaaS (Infrastructure as a Service). It uses Cloud Foundry as an open source PaaS. It starts by pushing code through Cloud Foundry, which plays the role of combining the code and suitable runtime environment based on the programming language in which the application is written. IBM services, third party services or community built services can be used for different functionalities. Secure connectors can be used to connect to on-premise systems and the cloud.

**Creating an app in Bluemix**
|
||||
In this article, we will create a sample ‘Hello World’ application in IBM Bluemix by using the Liberty for Java starter pack, in just a few simple steps.
|
||||
|
||||
1\. Go to [_https://console.ng.bluemix.net/registration/_][2].
|
||||
|
||||
2\. Confirm the Bluemix account.
|
||||
|
||||
3\. Click on the confirmation link in the mail to complete the sign up process.
|
||||
|
||||
4\. Give your email ID and click on _Continue_ to log in.
|
||||
|
||||
5\. Enter the password and click on _Log in._
|
||||
|
||||
6. _Set up_ and _Environment_ share resources in specific regions.
|
||||
|
||||
7\. Create Space to manage access and roll-back in Bluemix. We can map Spaces to development stages such as dev, test, uat, pre-prod and prod.

|
||||
|
||||
8\. Once this initial configuration is completed, click on_ I’m ready_. _Good to Go_!
|
||||
|
||||
9\. Verify the IBM Bluemix dashboard after successfully logging in, specifically sections such as Cloud Foundry Apps where 2GB is available and Virtual Server where 0 instances are available, as of now.
|
||||
|
||||
10\. Click on _Create app_. Choose the template for app creation. In our case, we will go for a Web app.
|
||||
|
||||
11\. How do you get started? Click on Liberty for Java, and then verify the description.
|
||||
|
||||
12\. Click on _Continue_.
|
||||
|
||||
13\. What do you want to name your new app? For this article, let’s use osfy-bluemix-tutorial and click on _Finish_.
|
||||
|
||||
14\. It will take some time to create resources and to host an application on Bluemix.
|
||||
|
||||
15\. In a few minutes, your app will be up and running. Note the URL of the application.
|
||||
|
||||
16\. Visit the application’s URL _http://osfy-bluemix-tutorial.au-syd.mybluemix.net/_. Bingo, our first Java application is up and running on IBM Bluemix.
|
||||
|
||||
17\. To verify the source code, click on _Files_ and navigate to different files and folders in the portal.
|
||||
|
||||
18\. The _Logs_ section provides all the activity logs, starting from the application’s creation.
|
||||
|
||||
19\. The _Environment Variables_ section provides details on all the environment variables of VCAP_Services as well as those that are user defined.
|
||||
|
||||
20\. To verify the application’s consumption of resources, go to the Liberty for Java section.
|
||||
|
||||
21\. The _Overview_ section of each application contains details regarding resources, the application’s health, and activity logs, by default.
|
||||
|
||||
22\. Open Eclipse, go to the Help menu and click on _Eclipse Marketplace_.
|
||||
|
||||
23\. Find _IBM Eclipse tools_ for _Bluemix_ and click on _Install_.
|
||||
|
||||
24\. Confirm the selected features and install them in Eclipse.
|
||||
|
||||
25\. Download the application starter code. Import it into Eclipse by clicking on _File Menu_, select _Import Existing Projects_ into _Workspace_ and start modifying the existing code.

使用IBM Bluemix构建，部署和管理自定义应用程序
|
||||
============================================================
|
||||
|
||||
|
||||
|
||||
|
||||
IBM Bluemix为开发人员提供了构建，部署和管理自定义应用程序的机会。Bluemix建立在Cloud Foundry上。它支持多种编程语言包括IBM的OpenWhisk，它允许开发人员调用任何函数但不需要资源管理。
|
||||
|
||||
Bluemix是由IBM实现的开放标准的基于云的平台。它具有开放的架构，其允许组织能够在云上创建，开发和管理其应用程序。它基于Cloud Foundry，因此可以被视为平台即服务（PaaS）。使用Bluemix，开发人员不必关心云配置，可以专注于他们的应用程序。 云配置将由Bluemix自动完成。
|
||||
|
||||
Bluemix还提供了一个仪表板，通过它，开发人员可以创建，管理和查看服务和应用程序，同时还可以监控资源使用情况。
|
||||
它支持以下编程语言：
|
||||
|
||||
* Java
|
||||
* Python
|
||||
* Ruby on Rails
|
||||
* PHP
|
||||
* Node.js
|
||||
|
||||
它还支持OpenWhisk（FaaS），这也是一个IBM的产品，其允许开发人员调用任一功能而不需要任何资源管理。

**IBM Bluemix如何工作**
|
||||
|
||||
Bluemix构建在IBM的SoftLayer IaaS（基础架构即服务）之上。它使用Cloud Foundry作为开源PaaS平台。它通过将代码推送到Cloud Foundry开始，Cloud Foundry通过使用其编写应用程序的编程语言，扮演了组合代码和适当的运行时环境的角色。IBM服务，第三方服务或社区构建的服务可用于不同的功能。安全连接器可用于连接本地系统到云。
