Learning AWS - Second Edition

By: Aurobindo Sarkar, Amit Shah

Overview of this book

Amazon Web Services (AWS) is the most popular and widely-used cloud platform. Administering and deploying application on AWS makes the applications resilient and robust. The main focus of the book is to cover the basic concepts of cloud-based development followed by running solutions in AWS Cloud, which will help the solutions run at scale. This book not only guides you through the trade-offs and ideas behind efficient cloud applications, but is a comprehensive guide to getting the most out of AWS. In the first section, you will begin by looking at the key concepts of AWS, setting up your AWS account, and operating it. This guide also covers cloud service models, which will help you build highly scalable and secure applications on the AWS platform. We will then dive deep into concepts of cloud computing with S3 storage, RDS and EC2. Next, this book will walk you through VPC, building real-time serverless environments, and deploying serverless APIs with microservices. Finally, this book will teach you to monitor your applications, automate your infrastructure, and deploy with CloudFormation. By the end of this book, you will be well-versed with the various services that AWS provides and will be able to leverage AWS infrastructure to accelerate the development process.

Using CloudWatch for monitoring

Amazon CloudWatch enables the monitoring of Amazon services, standard and custom defined metrics, and a variety of logs. Typically, you would want to retrieve metrics for analysis and/or integration with other monitoring tools. For example, you can use AWS Trusted Advisor to analyze your AWS configuration and usage, compare it to the best practices, and to alert you to opportunities to save on costs, help close security gaps, or improve system reliability and performance. CloudWatch provides APIs for retrieving hundreds of metrics by namespace, start and finish times, intervals, and so on.

CloudWatch logs can be monitored for errors, exceptions, HTTP response codes, Amazon S3 logs, and so on. In addition, you can also use the logs to correlate the system status with change events such as when AWS CloudFormation is used to rollout a new stack. We...
