Should You Use Multiple Availability Zones In The Cloud?
ITProToday, Friday, October 20,2023
The answer is it depends on whether your need for greater workload availability outweighs the increased costs, complexities, and network latency that come with employing multiple availability zones.
The ability to configure multiple availability zones is one of the factors that makes cloud computing so attractive. In the cloud, you can easily spread copies of your workloads across multiple sites using availability zones - a feat that would be much harder (and more costly) to achieve if you were hosting workloads in your own data center.
But how do you decide whether to set up more than one availability zone? And how many should you use? Getting the right answers to those questions is important for ensuring that you build the right level of redundancy into your cloud environments, while avoiding paying more than you need for availability zones that won't add value.
