Watch Learning AWS Lambda

Learning AWS Lambda from Packt Publishing starring Markus Klems is an educational video series that aims to teach its viewers about the AWS Lambda function, its implementation, and its implementation's scalability. The show has about eight hours of lessons in total and is ideal for developers who are interested in honing their skills regarding AWS Lambda.

The show starts with an introductory one-hour-long lecture that explains what AWS Lambda is, how it works, and its various advantages. The explanation is easy to understand for those who have previously worked with AWS and those who are new to the technology.

In the next few hours, Markus dives into Lambda's implementation and its usage. With a few examples, he walks the viewers through creating a Lambda function using AWS's command-line interface (CLI) and deploying it on the AWS Lambda console. Markus also delves deeper into Event Sources, which are key-value pairs that categorize different types of events and descriptions.

Another important aspect of this series is scalability. AWS Lambda can be scaled up and down according to demand, which means the cost of running the program is minimized as the program only runs when needed. With scalability, AWS Lambda enables developers to build microservices architectures that involve hundreds or thousands of independently scaled parts in their applications. The show covers how to use a scalable architecture for AWS Lambda functions and discusses how to store data in AWS S3, trigger an event in AWS SNS, and create a load balancer for the function.

It's also essential to note that AWS Lambda can be used in a wide range of industries, from finance to healthcare. The show covers different use cases for AWS Lambda and explains how the technology can be leveraged for different scenarios. For example, as explained in one of the episodes, AWS Lambda can be used for image processing, which involves resizing and optimization.

Another topic Markus covers in detail is the security implications of using AWS Lambda in a production environment. He explains how to secure the Lambda function and avoid different security pitfalls when using AWS Lambda. Security is an often-overlooked part of serverless architecture, but Markus stresses the importance of securing the function and its application programming interface (API).

Finally, the show teaches viewers how to migrate an existing application to the AWS Lambda function. The migration process, from the client side and server-side, can be cumbersome, but with AWS Lambda, it can be done easily. Markus walks viewers through every step of the migration process, from selecting the most suitable AWS Lambda service to modifying the code accordingly.

Overall, Learning AWS Lambda from Packt Publishing starring Markus Klems is a comprehensive guide that demystifies AWS Lambda and enables developers to create more scalable, secure, and cost-effective applications. The show is well paced, interesting, and enriched with real-world examples that demonstrate Lambda's potential. It would be an excellent resource for developers who are eager to learn about AWS Lambda's implementation and implementation's scalability.

Learning AWS Lambda is a series that ran for 1 seasons (23 episodes) between March 4, 2017 and on Packt Publishing
