IBM Bluemix
IBM Bluemix is a cloud platform as a service (PaaS) developed by IBM. It supports several
programming languages and services as well as integrated DevOps to build, run, deploy and
manage applications on the cloud. Bluemix is based on Cloud Foundry open technology and
runs on SoftLayer infrastructure. Bluemix supports several programming languages including
Java, Node.js, Go,PHP, Python, Ruby Sinatra, Ruby on Rails and can be extended to support
other languages such as Scala through the use of buildpacks. It took a team of people located in
different places only 18 months to build Bluemix from initial concept to public availability. It
was announced as a public beta in February 2014 and generally available in June.
Bluemix is the latest cloud offering from IBM. It enables organizations and developers to quickly
and easily create, deploy, and manage applications on the cloud. Bluemix is an implementation
of IBM's Open Cloud Architecture based on Cloud Foundry, an open source Platform as a
Service. Bluemix delivers enterprise-level services that can easily integrate with your cloud
applications without you needing to know how to install or configure them. This article gives a
high-level description of Cloud Foundry and Bluemix and outlines the features and services that
were part of the open beta of Bluemix, which make it a compelling PaaS in the market today.
What is Cloud Foundry?
Cloud Foundry is an open source platform as a service that lets you quickly create and deploy
applications on the cloud. Because of its open source roots, Cloud Foundry is not vendor
specific and does not lock you into proprietary software or cloud infrastructure. Cloud Foundry
abstracts the underlying infrastructure needed to run a cloud, letting you focus on the business
of building cloud applications. The beauty of Cloud Foundry is that it provides choice.
Developers and organizations can choose:
Development Frameworks: Cloud Foundry supports Java code, Spring, Ruby, Node.js, and
custom frameworks.
Application Services: Cloud Foundry offers support for MySQL, MongoDB, PostgreSQL, Redis,
RabbitMQ, and custom services.
Clouds: Developers and organizations can choose to run Cloud Foundry in Public, Private,
VMWare and OpenStack-based clouds.
Cloud Foundry's ability to provide choice comes through buildpacks, a convenient way to
package frameworks and runtimes. Buildpacks can be community based, custom built, or built
from scratch. In other words, if you cannot find a framework or service buildpack that suits your
needs, you could modify an existing buildpack or create your own. By using buildpacks,
companies are able to provide enterprise-level services like the Bluemix cloud offering.

What is Bluemix?
Bluemix is an implementation of IBM's Open Cloud Architecture, based on Cloud Foundry that
enables you to rapidly create, deploy, and manage your cloud applications. Because Bluemix is
based on Cloud Foundry, you can tap into a growing ecosystemof runtime frameworks and
services. In addition to providing additional frameworks and services, Bluemix provides a
dashboard for you to create, view, and manage your applications and services as well as
monitor your application's resource usage. The Bluemix dashboard also provides the ability to
manage organizations, spaces, and user access.
Bluemix provides access to a wide variety of services that can be incorporated into an
application. Some of these services are delivered through Cloud Foundry. Others are delivered
from IBM and third party vendors. New and enhanced services are added to the catalog often.

For developers, Bluemix further optimizes the time you spend creating cloud application. You
no longer have to be concerned about installing software or having to deal with virtual machine
images or hardware. With a few clicks or keystrokes, you can provision instances of your
applications with the necessary services to support them. This streamlining translates countless
hours of setting up, configuring, and troubleshooting into time spent rapidly innovating and
reacting to never-ending requirement changes.
For organizations, Bluemix provides a cloud platform that requires very little in-house technical
know-how as well as cost savings. Bluemix provides the rapid development environment
organizations need to react to users' demands for new features. The Bluemix platform and the
cloud provide the elasticity and capacity flexibility organizations require when their applications
explode in popularity.
For users, Bluemix represents the key that enables organizations to quickly deliver the features
they demand.
Bluemix provides the following features:
 A range of services that enable you to build and extend web and mobile apps fast.
 Processing power for you to deliver app changes continuously.
 Fit-for-purpose programming models and services.
 Manageability of services and applications.
 Optimized and elastic workloads.
 Continuous availability.
Bluemix abstracts and hides most of the complexities that are associated with hosting and
managing cloud-based applications. As an application developer, you can focus on developing
your application without having to manage the infrastructure that is required to host it. For
both mobile and web apps, you can use the pre-built services that are provided by Bluemix. You
can upload your web app to Bluemix and indicate how many instances that you want running.
After your apps are deployed, you can easily scale them up or down when the usage or load of
the apps change.

5. IBM Bluemix 2.5
You can use Bluemix to quickly develop apps in the most popular programming languages. You
can develop mobile apps in iOS, Android, and HTML with JavaScript. For web apps, you can use
languages such as Ruby, PHP, Java™, Go, and Python.
Bluemix also provides middleware services for your applications to use. Bluemix acts on the
application's behalf when it provisions new service instances, and then binds those services to
the application. Your app can perform its real job, leaving the management of the services to
the infrastructure.
In general, you don't have to worry about the operating system and infrastructure layers when
running applications on Bluemix. Layers such as root file systems and middleware components
are abstracted so that you can focus on your application code. However, you can learn more
about these layers if you need specifics on where your app is running.
Bluemix architecture
With Bluemix, you can access the public Bluemix platform, set up a dedicated Bluemix platform,
or use both.
Bluemix Public
At its core, Bluemix is an environment for you to develop apps and use services that provide
ready-to-use functions. Bluemix also provides an environment to host application artifacts that
run on an application server such as Liberty. By using SoftLayer, Bluemix deploys virtual
containers that host each deployed app. In this environment, the app can use pre-built services
to make app assembly easy.
As a developer, you can interact with the Bluemix infrastructure by using a browser-based user
interface. You can also use a Cloud Foundry command line interface, called cf, to deploy web
apps.
Clients—which can be mobile apps, apps that run externally, apps that are built on Bluemix, or
developers that are using browsers—interact with the Bluemix-hosted apps. Clients use REST or
HTTP APIs to route requests through Bluemix to one of the app instances or the composite
services.
The following figure shows the high-level Bluemix architecture.

6. IBM Bluemix 2.6
[ Figure 1 Bluemix Architecture ]
You can deploy your apps to different Bluemix regions, for latency or security considerations.
You can choose to deploy either to one region or across multiple regions. For more information.

7. IBM Bluemix 2.7
[ Figure 2 Multi-region application deployment ]
Bluemix Dedicated
Bluemix Dedicated is your own exclusive SoftLayer environment that’s securely connected to
both the public Bluemix and your own network. Bluemix Dedicated sits on your network
through a VPN or a direct network connection. Your single-tenant hardware can be set up in
any SoftLayer data center around the world. IBM manages the dedicated platform and
dedicated services, so you can focus on building custom apps. In addition, IBM performs all
maintenance to dedicated instances during a maintenance window selected by you.
IBM has several services that are available in your dedicated environment, but you can connect
to all public services. All runtimes are available in the dedicated environment.
All dedicated deployments of Bluemix include the following benefits and features at no
additional cost: VPN, private VLAN, firewall, connectivity with your LDAP, ability to leverage
existing on-premises databases and apps, 24/7 on-site security, dedicated hardware, and
standard support.

How Bluemix works
When you deploy an app to Bluemix, you must configure Bluemix with enough information to
support the app.
For a mobile app, Bluemix contains an artifact that represents the mobile app's back end, such
as the services that are used by the mobile app to communicate with a server.
For a web app, you must ensure that information about the proper runtime and framework is
communicated to Bluemix, so that it can set up the proper execution environment to run the
app.
Each execution environment, including both mobile and web, is isolated from the execution
environment of other apps. The execution environments are isolated even though these apps
are on the same physical machine.
When you create an app and deploy it to Bluemix, the Bluemix environment determines an
appropriate virtual machine (VM) to which the app or artifacts that the app represents is sent.
For a mobile app, a mobile back-end projection is created on Bluemix. Any code for the mobile
app running in the cloud eventually runs in the Bluemix environment. For a web app, the code
running in the cloud is the app itself that the developer deploys to Bluemix. The determination
of the VM is based on several factors, including:
 The load already on the machine
 Runtimes or frameworks supported by that VM.
After a VM is chosen, an application manager on each VM installs the proper framework and
runtime for the app. Then the app can be deployed into that framework. When the deployment
is completed, the application artifacts are started.
The figure 3 shows the structure of a VM, also known as Droplet execution agent (DEA), that
has multiple apps deployed to it:
In each VM, an application manager communicates with the rest of the Bluemix infrastructure,
and manages theapps that are deployed to this VM. Each VM has containers to separate and
protect apps. In each container,Bluemix installs the appropriate framework and runtime that
are required for each app.
When the app is deployed, if it has a web interface (as for a Java web app), or other REST-based
services (such as mobile services exposed publicly to the mobile app), users of the app can
communicate with it by using normal HTTP requests.

10. IBM Bluemix 2.10
Each app can have one or more URLs associated with it, but all of them must point to
the Bluemix endpoint. When a request comes in, Bluemix examines the request, determines
which app it is intended for, and then selects one of the instances of the app to receive the
request.
Bluemix resiliency
Bluemix is designed to host scalable, resilient apps and application artifacts that can both scale
to meet your needs, and remain highly available and quick to recover from
problems. Bluemix separates those components that track the state of interactions (stateful)
from those that do not (stateless). This separation allows Bluemix to move apps flexibly as
needed to achieve scalability and resiliency.
You can have one or more instances running for your app. When you have multiple instances
for one app, the app is uploaded only once. However, Bluemix deploys the number of instances
of the app requested, and distributes them across as many VMs as possible.
You must save all persistent data in a stateful data store that is outside of your app, such as on
one of the data store services that are provided by Bluemix. Because anything cached in
memory or on disk might not be available even after a restart, you can use the memory space
or file systemof a single Bluemix instance as a brief, single-transaction cache. With a single
instance setup, the request to your app might be interrupted because of the stateless nature
of Bluemix. A best practice is to use at least three instances for each app to ensure the
availability of your app.
All Bluemix infrastructure, Cloud Foundry components, and IBM-specific management
components are highly available. Multiple instances of the infrastructure are used to balance
the load.
Bluemix concepts
Bluemix consists of applications, services, buildpacks, and other components. You can deploy
applications to different Bluemix regions by using one IBM ID.
Regions
A Bluemix region is a defined geographical territory that you can deploy your applications to.
You can create applications and service instances in different regions with the same Bluemix
infrastructure for application management and the same usage details view for billing. You can
select the region that is nearest to your customers and deploy your apps to this region to get
low application latency. You can also select the region where you want to keep the application
data to address security issues. When you build apps in multiple regions, if one region goes
down, the apps that are in the other regions continue to run. Your resource allowance is the
same for each region that you use.

11. IBM Bluemix 2.11
If you are using the Bluemix user interface, you can switch to a different region to work with the
spaces in that region.
If you are using the cf command line interface, you must connect to the Bluemix region that you
want to work with by using the cf api command and specifying the API endpoint of the region.
For example, enter the following command to connect to Bluemix Europe United Kingdom
region: $ cf api https://api.eu-gb.bluemix.net
Infrastructure
Bluemix offers three ways for you to run your code: Cloud Foundry, IBM Containers, and virtual
machines. You can pick the right infrastructure for deploying your applications.
Cloud Foundry
Apps running in the Cloud Foundry infrastructure work with existing Cloud Foundry apps and
can bind to any of the services available in the Bluemix catalog. With this infrastructure, you
develop and manage your application code and Bluemix takes care of the management and
maintenance of the infrastructure that powers those apps.
IBM Containers
With the IBM Containers infrastructure, you can run your web app anywhere that supports
container deployment. A container is an object that holds everything that is needed for an app
to run. This infrastructure includes a private registry for your trusted images, so that you can
upload, store, and retrieve them. You can then make those images available in Bluemix and
manage your containers in the platform. The IBM Containers infrastructure scales both
horizontally and vertically. You can use all of the images that are available in the public Docker
Hub and use the docker API and command line interface to manage your containers on
Bluemix. IBM also provides some public images in the Containers Registry that you can use and
extend.
IBM Containers are used to run Docker containers in a hosted cloud environment. Docker adds
an engine that deploys an app to the virtual environment that you use for running your
containers. Docker also provides an environment that you can use to run your code. When
you're ready, it provides the means by which you can transfer the code from your development
environment, to your test environment, and then to your production environment.
Virtual Machines (BETA)
The Bluemix virtual machines infrastructure gives you the ability to create and manage virtual
machine groups on the IBM public cloud. You can also create and manage VM groups on your
private IBM clouds that you’ve chosen to make available to Bluemix users. The infrastructure
includes a guided experience to connect to your on-premises infrastructure. Support for

12. IBM Bluemix 2.12
monitoring and logging is integrated into Bluemix. You can deploy and manage your virtual
machines by using either the Bluemix user interface or the cloud's OpenStack APIs.
Virtual machines on Bluemix support provisioning of virtual machine groups with auto scaling.
Through this support, the number of instances can be automatically increased or decreased,
based on CPU load or the failure of an instance. In addition, load balancing is supported, which
enables the assignment of virtual IP (floating IP) addresses as needed.
To find out more about Bluemix virtual machines, see Virtual Machines in the Creating Web
Apps documentation.
Applications
In Bluemix, an application, or app, represents the artifact that a developer is building. The
application lifecycle in Bluemix and Cloud Foundry are identical, regardless of how you push the
app to the Bluemix. For more information, see How Applications Are Staged.
Mobile apps
Mobile apps run outside of the Bluemix environment and use services that the mobile apps are
exposed to. These services typically act in concert, and represent the back-end projection of
that app. Bluemix can also host app code that the developer would rather run on a back-end
server in a container-based environment.
Web apps
Web apps consist of all the code that is required to be run or referenced at run time. Web apps
are uploaded to Bluemix to host the app.
For languages such as Java, where the source code is compiled into runtime binary files, only
the binary files are required to be uploaded.
Services
A service is a cloud extension that is hosted by Bluemix. The service provides functionality that
is ready-for-use by the app's running code. The predefined services that are provided by
Bluemix include database, messaging, push notifications for mobile apps, and elastic caching for
web apps.
You can create your own services in Bluemix. These services can vary in complexity. They can be
simple utilities, such as the functions you might see in a runtime library. Alternatively, they can
be complex business logic that you might see in a business process modeling service or a
database.

13. IBM Bluemix 2.13
Bluemix simplifies the use of services by provisioning new instances of the service, and binding
those service instances to your app. The management of the service is handled automatically by
Bluemix. For all available services in Bluemix, see the catalog in the Bluemix user interface.
Starters
A starter is a template that includes predefined services and app code that is configured with a
particular buildpack. There are two types of starters: boilerplates and runtimes. A starter might
be app code that is written in a specific programming language, or a combination of app code
and a set of services.
Boilerplates
In Bluemix, a boilerplate contains an app and its associated runtime environment and
predefined services for a particular domain. You can use a boilerplate to quickly get up and
running. For example, you can select the Mobile Cloud boilerplate to host mobile and web apps
and accelerate development time of server-side scripts by using the mobile app template and
SDK.
Runtimes
A runtime is the set of resources that is used to run an app. Bluemix provides runtime
environments as containers for different types of apps. The runtime environments are
integrated as buildpacks into Bluemix, and are automatically configured for use.
Buildpacks
A buildpack is a collection of scripts that prepare your code for execution on the target PaaS. A
buildpack gathers the runtime and framework dependencies of an app. Then, it packages them
with the app into a droplet that can be deployed to the cloud.
If you do not specify a buildpack when you deploy your app to Bluemix, built-in buildpacks are
used by default.
BenefitsofIBM Bluemix
1. Simplicity and speed: By focusing on the DevOps model, Bluemix can reduce the downtime of
redeploying applications. Continuous delivery is one way this can be provided. The integrated
environment provided by Bluemix allows developers to automatically deliver code without the
hassle of building and debugging installation scripts. This reduces the time needed to manage
code delivery and puts it in the hands of the testers and user community faster. The application
can be deployed to multiple spaces which allow segregation of environments for development,
testing and production. Automatically delivering code keeps developers focused on coding, not
installation.

14. IBM Bluemix 2.14
2. Agility: Bluemix allows developers to focus on delivering business value, rather than on
maintaining the development environment, by scaling environments elastically based on
business demand. Instead of manually deploying workloads, Bluemix will automatically
redeploy workloads to other virtual machines (VMs) if there is an outage. To provide
continuous availability, Bluemix abstracts the underlying architecture and keeps the
manageability of services and applications at an easily understood level. Users are able to stop
or start applications and define how much memory is associated with each application while
Bluemix manages the rest.
3. Tools: With Bluemix, developers have the freedom to choose the development tools that
work best for them. Developers don’t always want to work with the same tool sets and Bluemix
provides several options, including the following:
• Command line: The Cloud Foundry (CF) command line provides integration for developers
that prefer coding without an integrated development environment (IDE). This is also helpful
for developing automation scripts with Bluemix. The CF application programming interfaces
(APIs) can be integrated with multiple languages, frameworks and services.
• Eclipse: Since Eclipse is widely used by developers, they can continue to use the tools with
which they are comfortable. The Cloud Foundry integration can be installed from the Eclipse
Marketplace. This provides integration with Bluemix from the Eclipse client.
• Web IDE: Developers can work with the Web IDE directly in Bluemix. This allows modification
of the application without any development environment installed on the developers’ laptops.
4. Source control: Bluemix also comes with integration to several source control management
(SCM) systems. These include Git, GitHub and Jazz SCM. These environments can be configured
to deliver application changes continuously. Open source Cloud Foundry applications can be
forked and loaded to Bluemix. This provides a great place to start development of a new
project.
5. Services marketplace: Services leverage APIs and software development kits (SDKs) that can
quickly and easily be incorporated with Bluemix applications. Although IBM provides many
services, Bluemix offers an open and flexible ecosystem which allows other companies to
provide services that can be integrated into applications. Companies can be both providers and
users of services. Two types of services are available:
