mazzle-starter VS terraform-cdk

I take advantage of I/O being parallel in Python in my mazzle continuous integration pipeline tool. I'm not sharing mutable state.

I spin up a graph of python Threads and each joins others in a graph. This way we can run graphs in parallel. See this graph - the parts that look like this:

dependency -> {parallel1; parallel2; parallel3} -> postparallel

parallel1, parallel2, parallel3 can run in parallel in a separate python thread because the IO is parallel.

postparallel joins parallel1, parallel2, parallel3 and waits for them all to complete.

Where parallel1-3 is things like ansible, packer (slow), AMI builds, chef runs etc.

I use a tool I wrote to layer my infrastructure with layers called components and I configure it with a Graphviz file.

My tool, called mazzle (previously devops-pipeline) would run parts of the graph that can run in parallel in parallel. It can also run parts of the build on SSH workers. You bring up the workers at the beginning of the build.

Here's an example of a graph generated from graphviz file: https://github.com/samsquire/mazzle/blob/master/docs/archite...

This graph brings up a hashicorp vault server, Java application, bastion proxy etc.

here's the graphviz file: https://github.com/samsquire/mazzle-starter/blob/master/arch...

It describes the ordering of the infrastructure, the invocation of Ansible, packer, shell scripts to set up vault etc.

The idea is to be able to bring up a new environment by changing one parameter. There's a React GUI too.

At first I tested it to deploy an OVHcloud Managed Kubernetes Service (MKS) with a Node Pool. And step by step, it worked. I even created a Pull Request (PR) in the terraform-cdk repository to add it as an example ☺️.

I'll be trying more sample app deployments with CDK and maybe even explore CDK for Terraform.

You can use CDK with other providers using https://github.com/hashicorp/terraform-cdk

In my experience, CDK is far better than Pulumi, especially if you're mostly going to be using AWS.

I, personally, prefer Crossplane Composite Functions on top of CDK8S, but had dropped CDKTF due to bloat. You can actually manage Kubernetes updates/upgrade lifecycle with Crossplane, as well.

I was going to recommend Pulumi, but looks like CDK for Terraform is still being kept up to date.

Avoid Pulumi, get directly to source and use https://github.com/hashicorp/terraform-cdk
