Introduction:

With the new architectural changes that will significantly improve Stratos capabilities and flexibility. In this hangout I am going to explain and discuss on following items,

• make the overall architecture more resilient and pluggable by using a message bus as the core communication system
• integrate both real-time and rule-based decision making into the decision making architecture
• support both HTTP and non-HTTP traffic in an equal manner for load balancing and elastic scaling purposes
• make the architecture support any LB, including hardware ones
• dynamic LBs and capability of auto scaling of LBs
• support composite application deployment
• bring LXC container handling into the cloud controller

Introduction:

At the movement, we are in the release of Apache Stratos 3.0.0 Incubation RC4. I'm going to demonstrate how to test RC4 packs with OpenStack.

Following is the agenda :

• How to configure stratos setup
• Run the stratos setup and install apache stratos packs
• Start the packs
• Create a tenant and subscribe to the php cartridge and demonstrate how it works

Introduction:

At the moment, the Stratos admin interfaces are tightly coupled to Carbon admin services. Hence All the backend interfaces are exposed as web-services. This in turn has encouraged developers to develop stratos controller front-ends as Carbon UI components.

It is possible to develop Stratos backend interfaces as RESTful services. The initial proposal is to develop them as a seperate JAX-WS webapp. But the topic is open for discusssion.

This would allow Stratos developers to,

• Create front-ends (simple web-apps) that make use of restful APIs.
• Commandline tooling can make use of REST APIs as well.

Following is the agenda:

• Carbon admin services and how frontend components interacts with them
• Stratos controller API (existing) and its UI components.
• What it takes to deploy a web-app in Carbon kernel
• Accessing core OSGi services by means of CarbonContext API
• JAX-RS web-app exposing admin services of Stratos - big picture
• How Custom web-app frontend/command line tooling can interact with the deployed REST apis.
