Summary: This section describes the Elastic Middle Services - a Technology preview with GigaSpaces XAP 7.1

Preface

Virtualization and cloud computing aim to solve a large part of the overhead involved in setting up the infrastructure (buying new hardware, setting it up, installing it, etc). Indeed, now we can start a new machine just by calling an API, we can lease a machine or even completely outsource our entire infrastructure to a public hosting provider.

The continuous demand for scale and scalability (due to growth of data volumes and demand for better efficiency) is forcing us to make our business more efficient. We spend a large amount of time on integration, maintenance and tuning which doesn't provide real value to our business.

Virtualization principles must be extended to higher levels of the application stack, to make it easier to manage, tune and integrate applications.

Assuming you can easily create a new machine by a call of an API... What would happen to your existing application when you add a new machine? Which part of your application would you run on that new machine? What do you expect would be the impact of the new hardware capacity on your application, in terms of latency/throughput or concurrent users?

Introduction

GigaSpaces Elastic Middleware Services are designed to simplify the creation and management of services, and are completely abstracted from the applications that use them. Elastic Middleware Services are very similar to cloud-based middleware like Amazon SimpleDB, but the major difference is that they are enterprise-grade, and can also be run as part of your private data center, for use by your internal enterprise applications.

These middleware services (messaging, data, Map/Reduce, etc.), simply extend the basic principles of virtualization to the middleware stack - smaller logical units, decoupled from physical resources, and abstracted to behave as one big unit.
