• Performance is based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput or performance that any user will experience will vary depending upon many factors, including considerations such as the amount of multiprogramming in the user’s job stream, the I/O configuration, the storage configuration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve results similar to those stated here.

Bluemix OverviewCloud platform for everyone

Bluemix is an open-standards, cloud-based platform for building, running, and managing applications.Build your apps, your wayUse the most prominent compute technologies to power your app: Cloud Foundry, Docker, OpenStack.

Extend apps with servicesA catalog of IBM, third party, and open source services allow the developer to stitch an application together quickly.

Scale more than just instancesDevelopment, monitoring, deployment, and logging tools allow the developer to run and manage the entire application.

Layered SecurityIBM secures the platform and infrastructure and provides you with the tools to secure your apps.

Deploy and manage hybrid apps seamlesslyGet a seamless dev and management experience across a number of hybrid implementations options.

Flexible Pricing Try compute options and services for free and, when you’re ready, pay only for what you use. Pay as you go and subscription models offer choice and flexibility.

Deeper DiveLiberty Buildpack

For Systems of Engagement applications and a lighter weight option for Systems of Record

• Full Java EE 7 Platform• Small footprint (~ 54MB), quick startup (< 3 sec)• Full fidelity to WebSphere Application Server Full

Profile• Distributed caching: Extreme scale as a feature• Add custom features and integrate 3rd party

components via Liberty extensions interface• Install new features from repository (local or remote)

with no server restart

WebSphere Application Server Liberty Profile

Buildpack for running applications on IBM WebSphere Application Server Liberty Profile.

Designed to run "packaged" servers and web applications.

Generates the liberty server configuration for a bound services

Simplify developers’ lives by requiring minimal configuration and making it easy to consume services

Loads into the server only what is needed for a running application

Supported Application Types

• Create a server package$ ./bin/server package myServer --include=usr

• Or, simply push a server config directory

$ cd /wlp/usr/servers/myServer$ cf push <appname>

Push an entire Liberty server package – complete with application(s), shared libs, drivers and server configuration.

Using Bluemix Services

• Create & Bind the service– Command line

• cf marketplace to see available services• cf create-service to create a service instance• cf bind-service to bind the service instance to your application• cf restart, or cf push again

– Web portal

• Read service connection and credentialsSample VCAP_SERVICES environment variable:

The following services have an easier way to consume them

The better way to consume services

SQL Database

Mongo DB

Modern “resource”

BLU Data Warehouse

Data Cache

Session Cache

Elastic MQ

Operational services

Log Analysis

Monitoring and

Analytics

Cloudant

Auto Scaling

Java EE standard “resource”

Using SQLDB service

26

The Java EE way – Sample code for using SQLDB

27

public class TestServlet extends HttpServlet { @Resource (name = "jdbc/mydb") private DataSource db;

// Alternatively use InitialContext lookup DataSource lookup = (DataSource) new InitialContext().lookup("jdbc/mydb");

“mydb” is the name of the service instance you create in Bluemix

That’s it! All familiar code, no changes required in order to make it work in cloud!

• No need for a server.xml• Don’t need to read VCAP_SERVICES

“mydb” is the name of the service instance you create in Bluemix

Java on IBM Containers

29

Docker

30

Fast, lightweight, isolated containers “Docker containers spin up fast and provide a layer of isolation from other services running in containers.” “The lightweight containers can spin up in a matter of seconds without consuming a lot of resources.”

vs

Docker Images

32

Read-only template used to create Docker containers

Build new images by modifying existing images

Find and share images on a registry (Docker Hub)

Sample Dockerfile

33

CLI: Test locally, push to Bluemix

34

docker build -t my_ibmliberty_image:v1 .

docker run --name my_liberty_container my_liberty_image

docker tag my_liberty_image registry.ng.bluemix.net/my_namespace/my_ibmliberty_image

docker push registry.ng.bluemix.net/my_namespace/my_liberty_image

Cloud ApplicationsBest practices

• Stateless– Ephemeral file system– Ephemeral memory

• Capture logs• Ports• Security

Coding Do’s and Don'ts

1. One codebase tracked in revision control, many deploys2. Explicitly declare and isolate dependencies3. Store config in the environment4. Treat backing services as attached resources5. Strictly separate build and run stages6. Execute the app as one or more stateless processes7. Export services via port binding8. Scale out via the process model9. Maximize robustness with fast startup and graceful shutdown10. Keep development, staging, and production as similar as possible11. Treat logs as event streams12. Run admin/management tasks as one-off processes
