and WAN optimization infrastructure that arbitrate the client connections

and ensure that application clients are connected to the right site, based on

the application's state.

When adapting the architecture and workflow process described in this

guide to fit the specific needs of your application, your infrastructure must

contain vCloud Director, vSphere®, BIG-IP LTM, and BIG-IP GTM

components at a minimum. You need to determine if vFabric SQLFire is the

right technology for your application, the right table structure, replication

scheme, and identify your key scaling metrics.

Note

In this guide, we refer to VMware’s vFabric SQLFire, however at the time

of our testing it was branded as GemStone SQL Fabric.

Configuration example

In the example scenario detailed in this guide, we use two instances of

vCloud Director in our lab; one represents a private cloud, and the other

represents a service provider’s public cloud. The two environments are

connected via a WAN emulator. Our example application is the JPetStore

demonstration application, together with VMware vCloud Director, vFabric

SQLFire®, BIG-IP LTM, BIG-IP GTM, and F5 iControl®. Necessary

application templates and virtualized infrastructure components have been

pre-positioned at a cloud provider in a dormant state, and are activated and

cloned as needed.

We used JPetStore, a freely available Java e-commerce application. In our

example we have modified the configuration to use the database caching and

replication technologies provided by the vFabric SQLFire product. We also

partitioned the database table-space to allow inter-site data replication for

order history and to maintain accurate inventory levels for order processing

Version Description

1.0 New deployment guide

1.1 • Changed GemStone SQL Fabric to vFabric SQLFire to reflect the

change in the product name.

• Clarifed the scenerio description in Configuration Example section.

itself.
