Mastering AWS Lambda by Udita Gupta

Key FeaturesLeverage AWS Lambda to significantly lower your infrastructure costs and deploy out massively scalable, event-driven systems and applicationsLearn how to design and build Lambda functions using real-world examples and implementation scenariosExplore the Serverless ecosystem with a variety of toolsets and AWS services including DynamoDB, API Gateway, and much more!Book DescriptionAWS 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! Youll 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!What you will learnUnderstand the hype, significance, and business benefits of Serverless computing and applicationsPlunge into the Serverless world of AWS Lambda and master its core components and how it worksFind out how to effectively and efficiently design, develop, and test Lambda functions using Node.js, along with some keen coding insights and best practicesExplore best practices to effectively monitor and troubleshoot Serverless applications using AWS CloudWatch and other third-party services in the form of Datadog and LogglyQuickly design and develop Serverless applications by leveraging AWS Lambda, DynamoDB, and API Gateway using the Serverless Application Framework (SAF) and other AWS services such as Step FunctionsExplore a rich variety of real-world Serverless use cases with Lambda and see how you can apply it to your environmentsAbout the AuthorYohan Wadia is a client-focused evangelist and technologist with more than 7 years experience in the cloud industry, primarily focused on helping customers succeed with the cloud.As a technical consultant for one of the worlds leading IT companies, Yohan provides guidance and implementation services to customers looking to leverage cloud computing through either Amazon Web Services, Windows Azure, or Google Cloud Platform, helping them come up with pragmatic solutions that make practical as well as business sense.Yohan is also an avid blogger and the author of two successful books:Learning VMware vCloud Air--2015Administering AWS: The Definitive Guide--2016He loves speaking about, blogging about, and training people on cloud platforms and technologies.Udita Gupta is an experienced cloud engineer with a passion for developing customized solutions, especially on the Amazon Web Services Cloud platform.
