are just some of the many open technologies
• Diverse set of services
• (103 IBM, 67 third-party)
• API Management & Integration

17. The twelve-
factor app
1. Codebase: One codebase that is tracked in revision control, with many deployments
2. Dependencies: Explicitlydeclareand isolate dependencies
3. Configuration: Store Configuration in the environment
4. Backingservices: Treat backing services as attached resources
5. Build, release, run: Strictlyseparatebuild and run stages
6. Processes: Executethe app as one or more stateless processes
7. Port binding: Export services with port binding
8. Concurrency: Scaleout using the process model
9. Disposability: Maximize robustness with fast startup and efficient shutdown
10. Development and production parity: Keep development, staging, and production as
similar as possible
11. Logs: Treat logs as event streams
12. Admin processes: Run administrative and management tasks as one-off processes

20. Cloud Foundry (aka Instant Runtimes)
• Open-source, managed by Cloud Foundry Foundation
• Simple to get started – just ‘cf push’
• Buildpack-based runtimes
• IBM Cloud provides hosted open-source Cloud Foundry, including
buildpacks for:
– Liberty for Java
– Node.js
– Swift
– ASP.Net Core
– Xpages
– Go
– PHP
– Python
– Ruby
– Tomcat

21. IBM Container Service: What is Docker?
• Open Software, Launched March 2013,
contributors include IBM, Red Hat, Google,
Microsoft, VMware, AWS, Rackspace, …
• Enables deployment of applications in
software containers
• Applications are wrapped in a complete
filesystem that includes Code, runtime, system
tools, and system libraries
• Will always run the same way, independent of
the environment
• Merely the most popular implementation of a
general concept of containers
• Docker is Linux-only

22. Kubernetes
• Kubernetes is a
container orchestrator
• Originally designed by
Google
• Provides:
• Declarative topology of
containers
• Automatic deployment
of containers to
resources
• Auto-scaling of
containers
• Ability to do rich secret
and configuration
management
• ….

24. By the way… what is Cloud
Private?
24
• A rethinking of local Cloud
capability
• An applicationplatformfor on-
premise cloud development,
basedon Docker and Kubernetes
• Includes:
• A PrivateImage Registry
• A ManagementConsole
• Monitoring Frameworks
• (Also has Cloud Foundry
capability)
Can get started with IBM Cloud Private-
Community Edition, available for free. Find out
more at: https://www.ibm.com/cloud-
computing/products/ibm-cloud-private/

25. IBM Cloud Functions (OpenWhisk)
Serverless application hosting, event-driven
execution
Programming model
– Rule := Trigger à Action(s)
Triggers could be:
– Events from REST, Cloudant, Watson, Weather,
etc.
Well suited to short-running interactions

32. Think about NFRs (the
difficult bits)

33. Integration - Networking
(IBM Cloud Public)
– Part of the public internet
– Internetworking with on-prem:
1. Use Service Gateway
2. Expose APIs from existing on-premise

35. Security
(IBM Cloud Public)
– Make everything run over HTTPS
– All CF runtimes are exposed publically; IBM Container Service provides more
granular capability
– Think about data residency – Cloud services can be provisioned anywhere:

36. Performance
Think horizontal scaling i.e. scaling is near-constant against number of instances
Implies stateless architectures (no more sessions)
This is the 12-factor concurrency principle: https://12factor.net/concurrency

37. Key Architectural Decision Points
37
• Which Compute Modelsto use?
• What microservices frameworks(if any) are you going to use?
• Which servicesto use?
• How are you going to network the cloud with on-premise?
• How are you going to functionally integratewithon-premise data?
• How are you going to ensure security (confidentiality& authentication)?
• How are you going to ensure performance?
• How are you going to ensure the solution is available?
• How are you going to backupand ensure the data is safe?
• We will follow the 12-factor approach.

38. DevOps – Toolchains +
Pipelines
Best-of-breed industry
toolchains
Customizable toolchain
templates, one click setup
Build pipelines for Cloud
Foundry, Containers, etc.

39. Things I’ve Definitely Oversimplified / Ignored
39
• WebSphere on Cloud – Potential Migration Path
• Microservices Frameworks (e.g. Istio)
• DevOps/CI/CD – see https://console.bluemix.net/devops/try-toolchains
• VMWare Solutions – see https://www.ibm.com/cloud/vmware
• Migration onto Cloud
• Management / Operations
• Integration choices
• … and lots and lots of other stuff
