Unidentified failures within the code can result in the reduced availability of the system. Overloading
of the system due to increased traffic causes the servers to become slow and unresponsive, reducing
availability to some of the clients. The condition of the equipment that is being used also affects
availability. With outdated hardware, you are guaranteed to have some problems.

First, build your applications with scalability in mind. This ensures that you are always prepared for
any increase in operation that may occur. Implement monitoring in critical areas of the components
that are directly involved in the delivery of the service, such as servers and databases. Monitoring
these components allows the company to take note of suspicious operations early on so that they
can then be investigated before causing downtime.

100% is a theoretical value, but something very close, like 99.99%, is very achievable. Instead of
building software for the number of clients you have, it is best to build a product with twice the
capabilities that are required at that particular moment. This allows for scaling to occur without
interruptions, and the system won’t be overloaded at any time.

Initially, setting up systems that can maintain availability to meet your expectations is expensive.
Automated monitoring and alerting systems will be required to ensure that every arising
abnormality is brought to your attention and is looked at. The monitoring software will enable the

company to make changes such as scaling upwards when there is growth. However in the long run
the benefits outweigh the initial cost.
