Overview of this book

AWS provides a vast variety of services for implementing Python applications, which can pose a challenge for those without an AWS background. This book addresses one of the more predominant problems of choosing the right service and stepping into the implementation of exciting Python apps using AWS. The book begins by showing you how to install Python and create an AWS account, before helping you explore AWS Lambda, EC2, Elastic Beanstalk, and S3 for Python programming. You'll then gain hands-on experience in using these services to build the Python application. As you advance, you'll discover how to debug Python apps using PyCharm, and then start deploying the Python applications on Elastic Beanstalk. You’ll also learn how to monitor Python applications using the CloudWatch service, along with creating and publishing APIs on AWS to access the Python application. The concluding chapters will help you get to grips with storing unstructured and semi-structured data using NoSQL and DynamoDB, as well as advance your knowledge using the Glue serverless data integration service in AWS. By the end of this Python book, you’ll be able to take your application development skills up a notch with AWS services and advance in your career.

What is CloudWatch?

When you deploy any application, it is important to track that it meets the set expectations regarding availability, performance, and stability. It is possible an issue may have occurred in the application. It’s important to note that some of the AWS services could be down or run incorrectly. This is a very bad experience from a customer’s point of view, and it would be better to observe these issues before the customer finds out. If you service an application via AWS, you need to use CloudWatch to monitor your applications to observe how they behave.

CloudWatch is a monitoring service in AWS; it provides different features to observe an application. The features of CloudWatch are as follows:

  • Collecting and storing logs from AWS services such as Lambda and EC2.
  • Providing a dashboard to monitor metrics and logs.
  • The ability to create an alarm. For example, if an application has consumed significant memory on a server, you can create...
