Implementing a Disaster Recovery and Business Continuity Plan
Cloud computing operations can be amazingly complex, as you have learned throughout this book. Failures can and will happen, often when least expected. It is important for you to expect that these failures are going to happen and plan for disruptions ahead of time so you can be ready when they occur.
Some outages, such as a web server failure, are relatively easy to plan for by implementing multiple web servers behind a load balancer. With the amount of virtualization in the cloud data centers, virtual machines can easily be replaced or moved quickly to new hardware platforms in the event of an outage. If a complete data center goes offline, then the complexity of recovery increases dramatically.
This section will discuss disaster recovery and business continuity.
You will learn about how to prepare for a disaster and the different architectures and reference designs for you to consider when creating a disaster recovery plan...
