DPA helps its customers to ensure high availability of servers, applications and services using failover clustering and load balancing in Microsoft Windows environment.
Providing the high availability key recourses is one of the top priorities for IT experts. It is well known that the effectiveness of the business, productivity and even revenues can be significantly affected by a failure of a key server, application or service.
Willing to avoid such disasters one should implement high-availability alternatives in Windows Server in order to moderate server outages for customers. The first step in designing a Windows-based high-availability solution entails understanding the two main high-availability alternatives available with Windows Server; failover clustering, and network load balancing. These options tackle high availability in different ways.
Failover clustering provides high availability by eliminating the threat of a single server, application or service failure. Normally, if a server with a particular application or service crashes, the application or service is unavailable until the administrator manually repairs the problem.
Meanwhile another server within the cluster will automatically take over the failed server's application and service responsibilities without intervention from the administrator or any impact on operations. This model minimizes server outage and downtime.
Generally such clustering and balancing is superior to other software solutions which distributes workload among multiple servers but does not provide the method for server availability.
