Deployment Topologies, High Availability, and Disaster Recovery
In today’s modern and cloud-native software world, you would think that it would be easy to simply click and deploy software. Amazon Web Services (AWS) made the public cloud ubiquitous. AWS made it easy for developers and enterprises to deploy their software and services pretty much anywhere in the world. The advent of microservices is supposed to make software easier to develop, deploy, and run. Also, Kubernetes and containers made delivering code and software even easier.
The old days of worrying about architecture and non-functional requirements such as High Availability (HA), multi-tenancy, and even Disaster Recovery (DR) are things of the past. However, this is not the complete truth: the new era of cloud computing, cloud-native, and cloud-ready software brings different and new challenges to these old-age concerns.
In this chapter, we will look at the following topics in the context of Cloud Pak for...
