Nowadays, we hear a lot about high availability and how important it is for data centers. But what does this word mean and why is high availability so important?
High availability (HA) means that the system should always be available to provide service to the users. What makes a system high available is its ability to recover from temporary failures without interruption in service. High availability is achieved when there are different strategies in place such as: backup, load balancing, redundant components or versions, and failover mechanisms.

Choosing a provider who can offer high availability web hosting options is important for business organizations, as it ensures that the website is always available.
There are many different providers who offer these options, and some of them are well-known hosting providers such as Amazon and IBM Softlayer. These providers offer virtual private servers (VPS) which allow you to utilize your own server and still have access to these high-availability features.

One of the most important metrics for a website is uptime, which is how much time a site spends online and working. A 99.99% uptime means that the site will be offline for less than 1 hour per month, which is almost unheard-of in today’s business environment.
Most people might not think about it much but when your site goes down, you’re missing out on potential revenue and customers. It could also cause bad reviews or unhappy customers to leave your company such as in the case of Amazon’s website outage in 2013.
Benefits of High Availability
keywords: benefits of high availability, how does it save time and money?
High availability can save time and money in a multitude of ways.
1- It eliminates the hassle of disasters. If there is a disaster in a data center, then all the servers will go offline. This means that all the online services will stop working, which can be very costly. In contrast, when there is high availability, if one of the servers goes offline, then other servers take over and provide redundancy for it so that it doesn’t affect service.
2- Redundant systems also have less downtime than single systems because they have two pieces of equipment instead of one for each component in a system. This means that when one piece fails or goes offline until it can be repaired or replaced, then the other piece picks up where it left off to keep things going even if
