Introduction to Clustering
This is my first blog post which I will be writing on Clustering. first let’s talk about what is Clustering and why we need it. Clustering is group of resources working together as a single organized system. We use clusters to provide High availability and also to distribute load among multiple servers.
Failover Clustering is available as a feature on Windows Server 2008 and also on Windows Server 2008 R2. this was previously called as Server Cluster with Windows Server 2003. Failover Clustering feature is only available on Enterprise/Datacenter and Itanium Editions and it’s not included in the Standard or the Web editions.
Other feature which I will be talking about is around Windows Network Load Balancing. this is a technology which we use to balance server workload cross multiple servers providing availability and scalability. Network Load balancing is available on Windows Server Web/Standard/Enterprise/Datacenter/Itanium and Foundation Editions.
In my future posts, I will focus on each technology and share knowledge on how Cluster technology could be used in our day to day life.
