Symantec's Dan Lamorena, Senior Product Marketing Manager, and Eric Hennessey, Director of Technical Product Management, introduce Veritas Cluster Server One.

Eric: Veritas Cluster Server One is the next evolution of Veritas Cluster Server, and its development has been driven by customer needs.

Veritas Cluster Server in its current form and architecture has been out for several years, and we found that we were starting to see limitations in what we could provide customers in very large, advanced environments-particularly those customers who are at the forefront of technology development and are quick to adopt new technologies to solve business problems.

These customer environments are multi-tiered. That is, they have a database server running on one OS platform, a middle tier application running on another, and a web tier on yet another. Veritas Cluster Server One gives these customers and their multi-tiered environments the ability to truly control these tiers of applications as the single business service that it really is.

Dan: These multi-tiered applications are complex. Take an online retailer, for example. When you go to the website, you see a number of places it can take you. You can make transactions thanks to an underlying transaction system. You can see a lot of product information that is stored in databases. You can view all your customer account data. And you can find out where and how to sell something yourself. All of these very complicated applications are integrated together. The trouble is, should one system go down, it can affect all of the other systems.

This kind of problem is one of the things that Veritas Cluster Server One addresses. Because so many of these applications have much closer integration now, you need visibility into the application environment and the ability to monitor all these different components in order to provide true high availability.

Eric: Exactly, because even if the database server is up, there are many other applications that connect to that database server and provide the actual visible services to the end user. As Dan just mentioned with the online retailer example, when you log in, you see a web page-so that tells you the web server is up. But if I then do a query on a certain book and the query fails, then something in the middle is broken and was not able to complete my request. So, I see the web page but for all intents and purposes, the application is down.

To maintain high availability in such an environment, you have to be able to manage not only the backend database that actually holds the data and takes the customer's credit card transaction, but all those moving parts in between as well, because if any one of those moving parts stops moving, then as far as the customer is concerned, the service is down.

Dan and Eric continue their introduction of Veritas Cluster Server One in part 2 of this blog.
