Overview of this book

CloudWatch is Amazon’s monitoring and observability service, designed to help those in the IT industry who are interested in optimizing resource utilization, visualizing operational health, and eventually increasing infrastructure performance. This book helps IT administrators, DevOps engineers, network engineers, and solutions architects to make optimum use of this cloud service for effective infrastructure productivity. You’ll start with a brief introduction to monitoring and Amazon CloudWatch and its core functionalities. Next, you’ll get to grips with CloudWatch features and their usability. Once the book has helped you develop your foundational knowledge of CloudWatch, you’ll be able to build your practical skills in monitoring and alerting various Amazon Web Services, such as EC2, EBS, RDS, ECS, EKS, DynamoDB, AWS Lambda, and ELB, with the help of real-world use cases. As you progress, you'll also learn how to use CloudWatch to detect anomalous behavior, set alarms, visualize logs and metrics, define automated actions, and rapidly troubleshoot issues. Finally, the book will take you through monitoring AWS billing and costs. By the end of this book, you'll be capable of making decisions that enhance your infrastructure performance and maintain it at its peak.

Section 2: AWS Services and Amazon CloudWatch


Monitoring is quite a large topic; a lot can be said about it. But what we have done in this chapter is to consider monitoring a natural human attitude and characteristic. The fact that anything that is built can fail means that there is a natural instinct to ensure that things are monitored, understood, and augmented to work better with time. We applied this concept to computing and explained that computing brings automation into this natural human process of monitoring, and we talked about the different components of monitoring computer systems. We covered logs, metrics, dashboards, and incidents and explained the meaning of each of these components. Next, we explained the importance of monitoring, pinpointing specific key reasons to monitor your application workload and infrastructure. Then, we moved on to explain Amazon CloudWatch, the AWS managed end-to-end monitoring service that is built with all of the features that any monitoring infrastructure or service will require. Lastly, the icing on the cake was the AWS Well-Architected framework, which serves as a boilerplate for everything cloud-native and monitoring is not left out.

This has given us a solid foundation to understand the fundamentals and components of monitoring and the importance of monitoring in the day-to-day activity of an SRE. We have also seen that CloudWatch is a managed service that takes away the operational expense of running our own cloud infrastructure. This foundational knowledge will be beneficial as we go deeper into this book.

In the next chapter, we will take our first step into Amazon CloudWatch to understand the components, events, and alarms.
