Summary
Brief introduction
In any case, it is not enough to deliver only a high-quality application with a rich set of features, and it must meet high availability conditions in more and more cases. Are you not upgrading your application because clustering technology looks too advanced to understand and use? With microsoft® Cluster Service (in windows® nt& #8482; Introduced in 4, and available in Windows. NET Server 2003, Enterprise Edition, and Datacenter Edition, developers can use simple tools to deploy applications in a clustered environment. These tools enable applications in the cluster to be registered as generic applications, and can use Windows scripting to control the configuration of the application.
A cluster connects two or more servers together so that it renders the client as a single computer. Connecting servers to a cluster can share the load, enable single point of operation/management, and provide a way to meet the growing needs of the corresponding adjustments. Therefore, high availability applications can be generated through clustering.
This article focuses on one of the three cluster-supported Microsoft server technologies: the Cluster service. We'll describe how to easily perform performance checks on an application in a clustered environment without changing the application code.
Three species set technique
The Microsoft server provides three clustering-enabled technologies: Network Load Balancing (NLB), Component load Balancing (CLB), and Microsoft Cluster Service (MSCS).
Network Load Balancing
Network Load Balancing, which serves as a front-end cluster for allocating incoming IP traffic in a server cluster, is an ideal choice for incremental scalability and significant availability for an E-commerce Web site. You can link up to 32 Windows. NET Enterprise servers to share a virtual IP address. NLB enhances scalability by assigning client requests across multiple servers within a cluster. As traffic increases, more servers can be added to the cluster, and any cluster can hold up to 32 servers. NLB provides a continuous service to users while also providing high availability, that is, automatically detect server failures and reallocate client traffic to the remaining servers within 10 seconds.
