4 Steps to Achieving High Availability in the Cloud
Constructing a high-availability application in the cloud can seem like a daunting process. The key is to assume that every component of a system will fail at some point and to prepare for that eventuality. Then you can build for failure and automate processes to handle it. Fault- tolerant systems that can achieve high availability — for example, 99.99% or 1 hour of downtime per year — are achievable in the cloud. Here is a four-step guide to achieving high availability in the cloud.
