Summary

In this chapter, we learned about the differences between the different types of services offered by GCP, from IaaS-type services, which offer the greatest flexibility but, at the same time, impose greater responsibilities, to SaaS-type services, which provide direct access to functionalities without the need to code the solution. We also reviewed concepts such as region, zone, high availability, and latency, and discussed what types of solutions we can apply to our designs in order to meet the needs in these areas.

We had a general introduction to the world of microservices, understanding the importance of structuring and writing logs that allow the traceability of unique events so that debugging and troubleshooting can be carried out. We understood that it is necessary to create tasks within our applications in an idempotent way in order to allow retries and anticipate the failure of calls between microservices.

We reviewed concepts that are key to implementing an auto-scalable solution, such as stateful versus stateless, and were able to understand the importance of designing a loosely coupled solution. In the next chapter, we will learn about security concepts and best practices to protect your applications in the cloud.
