This is the last post in this four-part series on high availability (HA). The focus of this post is HA in the cloud, which is challenging to discuss because the cloud is different depending on many factors. The cloud is different as it varies widely by service provider, i.e., IBM SoftLayer is significantly different from Amazon Web Services. The cloud is also different if you do it in house yourself with your own hardware and software integration or use ready-made Infrastructure as a Service like IBM PureSystems offerings designed to be up and running out of the box in as little as four hours.
