Micro Cloud in Your JVM with GridGain

You can launch as many GridGain nodes as you need in the single JVM

One of the features in GridGain’s In-Memory Data Platform that often goes unspoken for is ability to launch multiple GridGain nodes in the single JVM.

Now, as trivial as it sounds… can you start multiple JBoss or WebLogic or Infinisnap or Gigaspaces or Coherence or (gulp) Hadoop 100% independent runtimes in the single JVM? The answer is no. Even for a simple test run you’ll have to start multiple instances on your computer (or on multiple computers), and debug this via remotely connected debugger, different log windows, different configurations, etc. In one word – awkward…

Not so with GridGain. As I mentioned – you can launch as many GridGain nodes as you need in the single JVM. As the matter of fact – this is exactly how we debug complex internal algorithms here at GridGain System when we develop our product. We launch entire micro cloud of 5-10 nodes in the single JVM (right from our JUnits), put breakpoints into different nodes and walk in debugger through complex distributed execution path… never leaving a convenience of a locla IDEA’s debugger.

Naturally, all functionality (your tasks, access to data grid, clustering, messaging, CEP, etc.) work exactly the same way in a single JVM as it would on separate physical computers. You don’t have to adjust or reconfigure anything!

Now that’s the a productivity feature that most of us can appreciate.

The challenges of aggregating data from consumer-oriented devices, such as wearable technologies and smart thermostats, are fairly well-understood. However, there are a new set of challenges for IoT devices that generate megabytes or gigabytes of data per second. Certainly, the infrastructure will have to change, as those volumes of data will likely overwhelm the available bandwidth for aggregating the data into a central repository. Ochandarena discusses a whole new way to think about your next-gen applications and how to address the challenges of building applications that harness all data types and sources.
