Telling HPC and HAC apart
The main distinction runs between the high performance computing cluster (HPC) and the high availability cluster (HAC). An HPC system maximises performance, whereas an HAC puts the emphasis on data security. An HPC mainly serves to distribute load, while an HAC prioritises data redundancy so that a backup copy is always available. Both use load balancers to spread requests evenly across the servers in the cluster. In an HAC this optimises hardware utilisation and operation; in an HPC it increases the speed of data access. That gives a first impression of computer clusters and what the servers inside them do.
Practical uses of server clusters
In real-world scenarios such server groups are essential for critical IT services. Many leading companies run server farms in cluster configurations in order to handle large volumes of requests and to protect themselves against possible system failures. Rented clusters are an alternative approach. Providers such as centron offer a range of server solutions, from the basic model through to highly complex systems for customers who place great value on data security and performance.
