High availability systems provide redundant infrastructure that can be switched on manually or automatically when the primary network resources experience performance problems or failures of any kind.
In today’s IT infrastructure with an emphasis on always on demand it is imperative to design and implement a solution without a single point of failure, the use of high availability systems delivers this business practice but at what cost, and is this cost comparable with the loss of data, or time that a system failure would undoubtedly cost. A system fault can be caused by both internal and external factors, the most common are manufacturing defects or component defects due from wear out over a time period, the other major fault is due to specification and design errors of the system. Implementing a fault tolerant solution allows for both a planned and unplanned outage that will not cause a total system outage.
The planning of a fault tolerant system requires the design to accommodate numerous components of a system including multiple power sources to allow seamless continuation of its task.
Whether in the same data centre or across multiple states or counties ICE Systems can advise best practices to implement a high available system to allow your IT department to deliver on the business’ service level agreements. To implement a high available system every data path and component needs to be redundant.
What does your business need to survive in the event of a failure? Email connectivity for communication access to your clients needs and wants, web servers to provide the information or take that vital order. If there is a cost associated to your business with downtime you need to talk to ICE Systems about how to implement an HA environment.
Sophisticated clustering software allows application service processes to be distributed across multiple servers simultaneously in a load-balanced configuration to maintain constant delivery of determined acceptable performance.
