> The best optimization is simply shutting things off

This is the way.

A similar idea has been bouncing around in my mind for a while now. An ideal, turnkey system would do the following:

- Execute via Lambda (serverless).

- Support automated startup and shutdown of various AWS resources on a schedule influenced by specially formatted tags.

- Enable resources to be brought back up out of schedule when demand dictates.

- Operate as a TCP/HTTP proxy that can delay clients so that a given service can be started when it is dormant or, even better, the service isn't serverless but you want it to be. This can't work for everything, but perhaps enough things such that the need to run always on services is reduced.

Cloud Custodian [1] can purportedly do some of this, but I've been reluctant to learn yet another YAML-based DSL to use it.

So this is my "make things designed to be always-on serverless instead" project and the work AWS has done to make Java apps function on Lambda keeps me thinking about the potential to take things that 1) have a relatively long startup time and 2) are designed to be long running service loops, and find a way to force them into the serverless execution model.

Use a tool like this https://cloudcustodian.io/ to manage instance on/off hours or go fargate.

I'd use a combination of Cloudcustodian for start/stop scheduling and Apprise for notifications.

You can try Cloudcustodian. Very good tool to help you make a list of all underutilized instances. This also helps you do a lot more than that. https://cloudcustodian.io/

Cloud Custodian; rules engine for cloud security, cost optimization, and governance, DSL in yaml for policies to query, filter, and take actions on resources

Another alternative that I personally would use is CloudCustodian. It is a widely used tool for continuous cloud governance, detection and remediation. There is a CIS pack for it.

Note: Cloud Custodian kubernetes resources still work in progress. We can check the status of the plugin here.

‍Checkov is another great tool that examines your Terraform files (.tf), parsing the configurations and evaluating them against a comprehensive set of predefined policies. It scans Terraform-managed infrastructure and detects misconfigurations that could lead to security issues or non-compliance with best practices and regulations.

Bridgecrew — Infrastructure as code (IaC) security powered by the open source tool - Checkov. The core Bridgecrew platform is free for up to 50 IaC resources.

Kustomize: It provides a solution to customize the Kubernetes resource base configuration and differential configuration without template and DSL. It does not solve the constraint problem itself, but needs to cooperate with a large number of additional tools to check constraints, such as Kube-linter, Checkov and kubescape.

Checkov is a versatile static code analysis tool designed for infrastructure as code (IaC) and software composition analysis (SCA). It supports a wide range of technologies, including Terraform, CloudFormation, Kubernetes, Docker, and others, to detect security and compliance issues through graph-based scanning. Checkov also performs SCA scans, identifying vulnerabilities in open source packages and images by checking for Common Vulnerabilities and Exposures (CVEs). Additionally, it is integrated into Prisma Cloud Application Security, a platform that helps developers secure cloud resources and infrastructure-as-code files, enabling the identification, rectification, and prevention of misconfigurations throughout the development lifecycle.

For your Dockerfiles, you can also scan them. There are lots of tools that can check your Dockerfiles. They will validate if Dockerfile is compliant with Docker best practices such as not using root user, making sure a health check exists, and not exposing the SSH port. You can use Snyk and Checkov.

We use https://www.checkov.io/ for this, it's very simple to get started with and works really well as PR quality gate

Once there is a CI pipeline for delivering infra changes you can add static code analysis tools (checkov) and even start testing changes (terratest)

I just had a brief chat with one of the developers of Checkov and it sounds nice (and open source). I haven't had a chance to play with it, but if you want to it's at https://www.checkov.io/
