Summary of AWS re:Invent 2022 - Build your application easily & efficiently with serverless containers (CON309)

00:00:00 - 00:40:00

In this video, AWS re:Invent speaker Alex Williams discusses the benefits of using containers to build applications more efficiently and easily. He shows how using containers can speed up the development process on Greenfield projects, and how they can also help with the standardization and automation of application development on established software. Finally, he discusses the costs of using containers and how to account for them when developing an application.

• 00:05:00 Serverless technologies, such as Lambda and AWS app Runner, are helpful for building applications that can handle high concurrency. They allow for quick and easy development, while also minimizing costs and scaling well.
• 00:10:00 This video shows how to easily build applications using serverless containers (Lambda functions). With the help of Amazon eventbridges, you can tie in events to your Lambda functions, so they run in response to specific events. The Lambda pricing model is based on the time it takes to execute initialization code and the time it takes to invoke the function. When your application starts to get more traffic, you may need to start thinking about other models for running your code.
• 00:15:00 In this video, AWS re:Invent speaker Jess Morris demonstrates how to use a node.js event loop to process multiple requests concurrently. The use of multiple cores and load balancing can improve response time and prevent requests from timing out.
• 00:20:00 The app runner model used by AWS App Winner and AWS Lambda allows for the scaling of an application to handle increased traffic. App Runner starts by charging for memory, then charges for CPU, and finally charges for requests received. The model works well with businesses that have busy periods during the day, but may not be used at night.
• 00:25:00 AWS re:Invent is a time for developers to preview upcoming features and improvements to their applications. One of these features is serverless containers, which are Lambda-like containers that are managed by AWS. ABS 48 can patch the runtime and hosts inside containers, and provide patches to patches to the underlying hosts and time. ABS Fergie can also provide VMS on demand for applications. An orchestrator is a piece of code that helps developers plan and run their applications efficiently. With the choice of either Elastic Container Service (ECS) or Elastic Kubernetes Service (ESK), developers can choose the right orchestration for their applications. Lastly, Amazon API Gateway is a serverless ingress that can only receive requests, and not generate them.
• 00:30:00 The three different serverless options available to AWS customers are AWS Lambda, AWS App Runner, and AWS Fargate. Lambda has the lowest per-request cost, App Runner is cheaper when there is not much traffic, and Fargate has a constant price based on CPU and memory. All three options have scaling options down to the millisecond resolution. App Runner has the ability to optimize down to only charging for memory when there is no traffic, while AWS Fargate charges per second with a one-minute minimum.
• 00:35:00 AWS Lambda and AWS Fargate offer different abilities when it comes to dealing with spiky traffic and predictable patterns, respectively. AWS Lambda excels at workloads that are extremely spiky and have a few requests at a time, while AWS Fargate excels at high levels of traffic and stable patterns.
• 00:40:00 This video provides an overview of the three main AWS products - AWS App Runner, AWS Fargate, and AWS Lambda - and their respective advantages and disadvantages. App Runner is slightly more complex to set up than Fargate and Lambda, but offers more control over scaling and performance. Lambda is the simplest and most opinionated of the three, but may not be able to optimize costs as low as AWS App Runner or Fargate.
