In Chapter 6, Harnessing the Power of Cloud Computing, you saw how some characteristics of the cloud, such as elasticity, make the cloud so powerful. The ability to start instances on demand when needed and shut them down as soon as the demand subsides makes the cloud cost-effective and powerful. Because of the elasticity of the cloud, you can programmatically implement highly available systems, offer high reliability, and that can be automatically scaled up and down quickly.
In this chapter, you will explore in depth the concepts of availability, reliability, and scalability and why understanding them is critical to your projects' success. You will also learn which AWS services can be used to make your applications highly available, fault-tolerant, and massively scalable.
In this chapter, you will cover the following topics:
- Availability in cloud computing
- Reliability in cloud computing
- Scalability in cloud...
