As a suite of products, vFabric offers a single SKU model that includes the entire suite. Besides offering an economically beneficial licensing model that is flexible, based on average use, and hardware independent, the vFabric team has developed the vFabric Administration Server (VAS) to help make installation, configuration, and operations easier.
If you missed a previous article explaining how VAS work and what it can do for you, VAS is based on a single system image design (SSI) and allows you to define a group of nodes where each operation on the group is applied to each node who is a member of the group. This approach provides time savings and reduces errors by keeping systems more consistent, allowing easier ways to scale, and simplifying administration. VAS also provides a robust set of REST APIs for virtually all of its functionality. In addition to vFabric tc Server, VAS can manage vFabric RabbitMQ, vFabric GemFire, vFabric SQLFire, and vFabric Web Server. VAS 1.1.1 was recently released with new features and many bug fixes.
In this article (and demonstration further below), we will show you six steps that give you an idea of how easy it is to provision using VAS. We will show you how to install VAS and use it to provision vFabric tc Server across three nodes along with a WAR file. The explanation below refers to examples from RubyGems.org and GitHub/vFabric/VAS-Ruby-API along with the latest VAS documentation.
