terraform-aws-vpc VS aws-cloudformation-coverage-roadmap

In the terraform block we have to specify a path to a Terraform module. For example, in this case, we use the VPC module from the terraform-aws-modules open source project. We don't necessarily need to rely on other people's code, we can use modules maintained by ourselves by providing a link to a remote Git repository, or we can even have it point to a local path on our drive.

ECR VPC ECS

Now let us move on to the important part of the tutorial. Creating an EKS cluster in AWS is not as straightforward as in other cloud platforms. You need to also create a lot more resources for everything to work correctly without surprises. You will be using a bunch of Terraform providers to help with this, and you will also use some prebuilt Terraform modules like AWS VPC Terraform module and Amazon EKS Blueprints for Terraform to reduce the amount of boilerplate you need to write.

The infrastructure is created using terraform, and can be found in this git repository. The project uses community maintained AWS Terraform modules, which simplify this process. The code examples that follow in the post are using the vpc-endpoints module to create the Gateway and interface endpoints.

Let us use an example from AWS to see how we can use a publicly available module. When setting up a virtual network (or Virtual Private Cloud, VPC) in AWS there are a lot of resources you must create. One popular module is the AWS VPC module. The documentation for this module is available at registry.terraform.io/modules/terraform-aws-modules/vpc/aws. The simplest example of using this module looks like this:

locals { region = data.aws_region.current.name } module "vpc" { source = "git::https://github.com/terraform-aws-modules/terraform-aws-vpc.git?ref=v3.16.0" name = var.vpc_name cidr = var.vpc_cidr azs = ["${local.region}a", "${local.region}b"] public_subnets = cidrsubnets(var.vpc_cidr, 1, 1) enable_dns_hostnames = true enable_dns_support = true map_public_ip_on_launch = true tags = { Name = var.vpc_name } public_subnet_tags = { Name = "public subnet" "kubernetes.io/role/elb" = "1" "kubernetes.io/cluster/${var.cluster_name}" = "shared" } }

/u/akirakotkata all of the answers in this thread are correct, but nobody's empowered you to figure this out on your own in the future. In the registry link you provided, there's a link to Source Code. Follow that link and take a look at variables.tf in the repo, lines 13-17. That block is what is expected for the parameter, so you need to tweak what you're sending into what it expects.

Given AWS CloudFormation is AWS's native language and service for infrastructure as code, you will likely find more official quickstarts provided by AWS in the language. In addition to this, AWS Support will probably be more capable of assisting you with issues when you need help. AWS Support is essential for large enterprises, particularly those new to the cloud or slow to adopt. These types of organizations may have a skill gap within their organization regarding their cloud skill set, and in turn, they are more likely to use AWS Enterprise Support.

Today, I will show you how to build Amazon Location Service, which allows you to build location-based applications within your AWS environment using AWS Cloud Development Kit (AWS CDK) and AWS CloudFormation. I will also show examples of the recently popular CDK Migrate and AWS CloudFormation IaC generator.

AWS CloudFormation: Speed up cloud provisioning with infrastructure as code.

Infrastructure as Code (IaC) is an important part of any true hosting operation in the public cloud. Each of these platforms has their own IaC solution, e.g. AWS CloudFormation. But they also support popular open-source IaC tools like Pulumi or Terraform. A category of tools that also needs to be discussed is API gateways and other app-specific load balancers. There are applications for internal consumption, which can be called microservices if you have a lot of them. And often microservices use advanced networking options such as a service mesh instead of just the native private network offered by a VPC.

Cloudformation (IaC) does not need to be introduced to anyone, plus if you read the previous blogpost, the terraform provider (CC) we used is based on Cloudformation. Moreover, you will notice a lot of similarities, after all, we are implementing the same scenario, but with a different tool.

AWS Application Composer launched in the AWS Console at re:Invent one year ago, and this re:Invent it expanded to the VS Code IDE as part of the AWS Toolkit - but that’s not the only exciting part. When using App Composer in the IDE, users also get access to a generative AI partner that will help them write infrastructure as code (IaC) for all 1100+ AWS CloudFormation resources that Application Composer now supports.

CloudFormation

Of course, best practices today dictate that we should be deploying our infrastructure as code, using tools such as CloudFormation or Terraform.

If you're provisioning the above resources for the first time, you'll have to either configure Terraform to use specific AWS keys as you won't have OIDC connection yet. In my case, I chose to have those pre-requesites resources in a CloudFormation template and deploy them with StackSets.
