Stratos - an Open Source Cloud Platform

Presentation given by WSO2, the producer of Stratos cloud-reated products. Here's some pointers from their presentation. I think this should interest all our people working on SOA implementation.

Presentation slides here.

Slide 1

• Presentation of Platform as a Service (PaaS)
• online data doubles online every 15 months and the number of apps kind of follow the same trend
• what the Cloud is really depends on who you are (ex: online music for teenagers, emails for your mom, prospects for a sales guy, etc.)

Slide 2:

• PaaS (Platform as a Service) is what is positioned between IaaS (Infrastructure as a Service, ex: Amazon) and SaaS (Software as a Service, ex: Google Apps)
• Stratos tries to insert itself in between the hardware and the software platforms.

Slide 3:

What does Cloud native means:

• Distributed/Dynamically wired (i.e. it works properly in the cloud)
• Elastic (i.e. it uses the cloud efficiently)
• Multi-tenant (i.e. it only costs when you use it)
• Self-service (i.e. you put it in the hands of users)
• Granularity billed (i.e. you pay for just what you use)
• Incrementally deployed and tested (i.e. it support seamless live upgrades - Continuous update, SxS, in-place testing and incremental deployment)

Slide 4:

Apply those concepts to an Enterprise architecture… Cloud is no only about Web apps, it is also about Portal, Queues and topics, DB, Registry/Repositories, Rules/CEP queries, Integrations, etc.

Slide 5:

What are the various dimensions to evaluate a PaaS:

• Which languages and APIs does it support? (Are you locked in?)
• Can it run on a private cloud? (Are you locked in?)
• Which services does it offer? (Are you locked in?)
• Is it open source? (Are you locked in?)

Slide 6:

What are the cloud players:

1- Those without private PaaS

• Force.com / Heroku
• Google App Engine
• Amazon Elastic Beanstalk

2- Those with provate PaaS

• Tibco
• Microsoft
• Cloudbees

3- Those with both

• Stratos (obviously...)
• others I missed.

Slide 6:

What is Stratos

• A product: Open source, based on OSGi
• Services (based on the product) called Stratos Live

Then we got a live demo of Stratus Live

For more details, see http://wso2.com/cloud/stratos/

This maybe interesting for App server, ESB, Repositories, etc. seems to be a fairly complete, consistent, integrated portfolio of middleware services.

Here's a list of what they claim their offer in Stratos Live:

1. Application Server as a service
2. Data as a service
3. identity as a service
4. Governance as a service (this one is for Pascal!)
5. Business Activity Monitoring as a service
6. Business Processes as a service
7. Business Rules as a service
8. Enterprise Service Bus (ESB) as a service
9. Message Broker as a service
10. etc.
