Testing Serverless Applications on AWS
For context; the web application is built with React and TypeScript which makes calls to an AppSync API that makes use of the Lambda and DynamoDB datasources. We use Step Functions to orchestrate the flow of events for complex processing like purchasing and renewing policies, and we use S3 and SQS to process document workloads.

Serverless APIs
AWS AppSync I'm keeping this section a bit shorter for you all, since AppSync is not something I have actually used personally, but have heard great things about. AppSync is another API option AWS has made available specifically for applications that want to take advantage of GraphQL or a Publish/Subscribe model. The GraphQL model may be of interest to front end developers that need to query multiple sources of data from one API endpoint, like databases or microservices. The Pub/Sub model I am more familiar with in the IoT hardware-communicates-with-software aspect, however this is also powerful for frontend developers looking to take advantage of real-time updates with serverless WebSocket connections. With AppSync, you also have caching, offline data synchronization, and real-time updates. You can learn more and check out the developer docs on the AWS Website.

How To Reduce Operational Costs With AWS Lambda
So AWS Lambda is basically a serverless computing service that is offered by AWS. It enables developers to run the code in response to various events. It protects the developers from the pain of managing the servers. Using a serverless execution model helps the developers to handle provision, manage and scale the servers automatically. Through this approach the developers can fully focus on writing the code instead of dealing with other aspects.

The 2024 Web Hosting Report
The first product that popularized the term “serverless” was AWS Lambda, which is both the prototypical and archetypical function as a service provider. It also has a great name, which pings back to its envisioned place in the cloud of the future. In computer programming, a lambda, often referred to as a lambda function or lambda expression, is a concise way to represent an anonymous function, which is a function without a name. The concept originates from lambda calculus in mathematical logic and has been adopted by many programming languages, each with its own syntax and characteristics.

Use custom rules to validate your compliance
You can build a custom config rules in 2 ways, using AWS Lambda and CloudFormation Guard. Lambda gives you a lot of flexibility, but it also brings complexity of maintaining. CloudFormation Guard is a bit more lightweight in that regard. Yes, you still need to maintain the logic to determine when your resource is compliant or not. But you need to do this in both cases, thus my go to preference is CloudFormation Guard.

Refactoring a serverless application to use Step Functions third-party API call integration
I use the OpenWeather API to receive the current temperature data by providing the latitude and longitude coordinates as query strings in the request. A Lambda function invokes the weather API and sends the current temperature value as a custom metric to CloudWatch. I then graph the temperature values on a dashboard and activate an alarm when the temperature sinks below zero degrees Celsius.
