AWS CodeDeploy is a deployment service that automates application deployments to Amazon EC2 instances, on-premises instances, serverless Lambda functions, or Amazon ECS services. A compute platform is a platform on which CodeDeploy deploys an application. There are three compute platforms:

When we deploy code at Aha! we kick off a number of AWS CodeDeploy tasks running in parallel. Here's some code to simulate deployment:

AWS has a service named CodeDeploy for this. It does exactly what you describe.

AWS CodeDeploy is a fully managed deployment service that automates software deployments to various compute services, such as Amazon Elastic Compute Cloud (EC2), Amazon Elastic Container Service (ECS), AWS Lambda, and your on-premises servers.

AWS's developer suite of products includes the AWS CodeDeploy offering, which can help developers deploy AWS Lambda functions and other compute-related services.

AWS? Dude, use CodeDeploy green blue with hooks.

AWS CodeDeploy is a service from Amazon Web Services that automates deployments to any instance. It works with any language, platform, or application. AWS CodeDeploy makes it easier to release new features quickly, avoid downtime during application deployment, and handle the complexity of updating applications. Users can also test and track deployments so they're not left guessing or digging through logs when something goes wrong. Our integration with AWS CodeDeploy can be integrated directly into your CI/CD pipeline to improve your AWS DevOps security.

If you have a BFF, that means you have a front-end. If you have a front-end, you gotta host it somewhere. Amplify is an AWS managed service built for hosting Single Page Applications. It abstracts away all the existing serverless tech you’d traditionally use on AWS into a single place, automating most of it. S3 static asses, cache busting on deploy, and it even abstracts it’s own build pipeline using CodeDeploy sourced right from your code repository. Like AppSync, it creates a CloudFront distribution for you, and optionally provides automatic Route53 creation if you want at full URL.

Once a fresh build passes via CodePipeline, CodeDeploy distributes the functioning package to each instance based on your predefined settings. This makes it easy to coordinate builds and upgrade or patch simultaneously. CodeDeploy is code-agnostic and includes typical old code with ease. Every deployment instance can be readily monitored using the AWS Management Console, and any mistakes or issues may be rolled back through the graphical user interface.

AWS Lambda simplifies composable applications by offering serverless execution, seamless integration with AWS services, automatic scaling, and cost efficiency without the need to manage servers.

Deploying Dart functions to AWS Lambda enables you to utilize them not only within AWS Lambda but also integrate them with services like Amazon API Gateway, allowing you to leverage them in Flutter applications as well. This unified codebase in Dart offers great convenience.

Event Producers: Generate streams of events, which can be implemented using straightforward microservices with AWS Lambda (for serverless computing), Amazon DynamoDB Streams (to captures changes to DynamoDB tables in real-time), Amazon S3 Event Notifications (Notify when certain events occur in S3 buckets) or AWS Fargate (a serverless compute engine for containers).

Amazon Web Services (AWS) Lambda is a serverless function-as-a-service (FaaS) platform that lets you deploy, run, and scale code in the cloud as self-contained functions without having to manually configure any infrastructure. Lambda runs your functions on demand in response to specific events, such as an HTTP request from the internet or activity in another AWS service.

FaaS is specifically focused on building and running applications as a set of independent functions or microservices. Major cloud providers like AWS (Lambda), Microsoft Azure (Functions), and Google Cloud (Cloud Functions) offer FaaS platforms that allow developers to write and deploy individual functions without managing the underlying infrastructure.

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 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.

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.
