Summary
In this chapter, we introduced the cloud and some of its concepts, such as on-demand self-service, resource pooling, multi-tenancy, elasticity, and scalability. We learned about the history of the cloud and discussed the key motivators for businesses to move to the cloud. We categorized the cloud service models and deployment models before looking at some of the commonly used cloud vendors and learning about their infrastructure in detail.
After that, we discussed when we should use a specific cloud model and the factors to consider while choosing a specific model. We familiarized ourselves with concepts such as public, private, hybrid, multi, and community cloud models while looking at each model’s benefits and additional factors to consider.
These concepts should have given you an in-depth understanding for the next chapter, where we will focus on cloud migration fundamentals and the different phases of cloud migration.
