Cluster computing systems
Today i attended a class on Distributed systems,lecturer took us through introductions to concepts on distributed systems and system models.later in the day i found myself learning much more on cluster computing.This will summarize everything i learnt.
A computer cluster is a single logical unit consisting of multiple computers that are linked through a LAN (local area network). The networked computers essentially act as a single, much more powerful machine.
advantages of computer cluster are:
provides much faster processing speed, larger storage capacity, better data integrity, superior reliability and wider availability of resources.
Computer clusters are, however, much more costly to implement and maintain. This results in much higher running overhead compared to a single computer.
Types of computer clusters:
- Load-balancing clusters
- High availability (HA) clusters
- High performance (HP) clusters
