3. Agenda
• Cloud Computing
• Cloud Native Properties
• WSO2 Stratos Overview
• Features of WSO2 Stratos

4. Cloud Computing
• Ability to buy computational power, storage or
services on demand
• Service Delivery Model
– What is given “as a Service”
• Cloud Deployment Model
– Where is it deployed

5. Service Delivery Model

12. Cloud Native
• Elastic (Uses the cloud efficiently)
• Scales up and down as needed
• Works with the underlying IaaS
• Self-service (in the hands of users)
• De-centralized creation and management of tenants
• Automated Governance across tenants
• Multi-tenant (Only costs when you use it)
• Virtual isolated instances with near zero incremental cost
• Implies you have a proper identity model
• Granularly Billed and Metered (pay for just what you use)
• Allocate costs to exactly who uses them
• Distributed/Dynamically Wired (works properly in the cloud)
• Supports deploying in a dynamically sized cluster
• Finds services across applications even when they move
• Incrementally Deployed and Tested (seamless live upgrades)
• Supports continuous update, side-by-side operation, in-place testing and
incremental production

13. Cloud Native Middleware

14. Stratos Meets Enterprise Expectations
• All angles of enterprise architecture expectations are covered
– Not just developers, but aimed at integration specialists as well
– Industry standard model (Webapp, ESB , BPEL, web services)
• No vender lock-in
– No {Service provider, data , programming model} lock-in
– In almost all cases Identity, Cache, Data access are all proprietary and
specific to the PaaS
• An Enterprise-ready PaaS based on SOA architecture and Open
Standards
– ESB, BPMS, BRMS, BAM, Portal
• Open source
– with Apache License (version 2)

16. User Experience of Stratos

17. StratosLive vs Stratos
• StratosLive - a Platform-as-a-Service
– contains all the “Services” in a default / vanilla state
• Stratos can contain:
– More services
• e.g. New services you create
– Fewer services
• e.g. just AS/DSS
– Customized deployments of services
• e.g. ready configured with libraries / APIs / host objects

29. Governance of Application
Development
• Too many projects fall through the cracks and use non-
standard infrastructure, build, governance
• Projects use too many different unknown or unapproved
libraries, frameworks, etc
• No clear idea of which projects are at which stage
• Few or no metrics on code quality, test coverage, re-use
• Little automated build or test
• Best practices are not applied everywhere
