Mastering AWS Lambda

By: Yohan Wadia, Udita Gupta

Overview of this book

AWS is recognized as one of the biggest market leaders for cloud computing and why not? It has evolved a lot since the time it started out by providing just basic services such as EC2 and S3 and today; they go all the way from IoT to Machine Learning, Image recognition, Chatbot Frameworks, and much more! One of those recent services that is also gaining a lot of traction is AWS Lambda! Although seemingly simple and easy to use, Lambda is a highly effective and scalable compute service that provides developers with a powerful platform to design and develop Serverless event-driven systems and applications. The book begins with a high-level introduction into the world of Serverless computing and its advantages and use cases, followed by a deep dive into AWS Lambda! You’ll learn what services AWS Lambda provides to developers; how to design, write, and test Lambda functions; as well as monitor and troubleshoot them. The book is designed and accompanied with a vast variety of real-world examples, use cases, and code samples that will enable you to get started on your Serverless applications quickly. By the end of the book, you will have gained all the skills required to work with AWS Lambda services!

Monitoring Lambda functions using Datadog

Although CloudWatch and X-Ray are really awesome tools, there are times when these tools are simply not enough to work with at an enterprise level. This can hold true for a variety of reasons; take for example maturity--now, although X-Ray provides you with some real time trace statistics, it's still a very young service and will take time to evolve, into say, something provided by an enterprise transaction monitoring tool such as Dynatrace. Dynatrace actually leverages artificial intelligence to detect performance and availability issues and pinpoints their root causes; something that X-Ray doesn't support today. The same can be said for CloudWatch as well. Although you can monitor your AWS infrastructure using CloudWatch, sometimes you may require some extra tools such as Datadog, New Relic, Splunk, and so on to do some customized...
