Achieving Website High Availability

When someone says a website is available, they mean that they can access that website. The application they’re trying to reach is up and working properly. High availability means that the website is up most of the time throughout the year. Companies can even put a percentage on this, striving for 100% availability, but typically getting somewhere a bit less, such as 99.9% or 99.99%.

What Is Load Balancing

Load balancing means splitting up network traffic so that you can distribute it evenly across a group of backend servers. For example, if you run two web servers, both hosting a copy of the same website, then you can balance the traffic across them, sending half to one and half to the other. The goal of load balancing is to increase the availability of your website or web-based application by routing a portion of requests to each server.
