Most of us are familiar with Spring mostly as platform for
simplifying the development of our JEE applications using POJO based
approach. Our solution still rely J2EE as the container for addressing
the high availability and scalability of my application. In most of
high performance/low-latency environment this combination was hardly
sufficient and most people found themselves building infrastructure
outside the JEE stack to address their scalability and performance
requirement. In most cases this was achieved by turning their Tier
based application into SOA/EDA combining In-Memory-Data-Grid (IMDG)
share state between their services and Messaging Bus (ESB) to enable
loosely couple communication between those services.
In this session we will introduce a new framework - OpenSpaces that takes those different patterns and creates a simple platform on top of Spring - OpenSpaces. Openspaces simplify significantly the way we can build such applications by integrating POJO driven services with the Data and scale them out as a single unit - a processing-unit.
Light weight SLA driven containers enables the deployment and management of those services over a dynamic pool of machines, in addition to that we will discuss how in future OSGI will be used to provide dynamic services and enable the management of their lifecycle independently even if they share the same VM. All this together makes the entire development of large scale application as simple as writing any other standalone Spring application today.
