What is Network Load Balancing Service?
• Network Load Balancing clusters enable you to manage a group of independent servers as a single system for greater scalability, increased availability, and easier manageability. One can use Network Load Balancing to implement enterprise-wide scalable solutions for the delivery of TCP/IP based services and applications. It is not a service based application, it only redirects traffic on a particular protocol so that the load between the server is easily distributed. What is SQL Clustering Service? • Cluster Service acts as a back-end cluster; it provides high availability for applications such as databases, messaging and file and print services. Multiple servers (nodes) in a cluster remain in constant communication. If one of the nodes in a cluster becomes unavailable as a result of failure or maintenance, another node immediately begins providing service, a process known as ‘failover’. MSCS attempts to minimize the effect of failure on the system as any node (a server in the cluster)
