CDK Speedster - fast Lambda deployment

Thumbnail

CDK is great for serverless architectures. But the deploy times even for small lambda functions is to slow.

Here is a little trick which can speed up things a lot. A small caveat: It is cheating.

The CDK pipeline construct

Thumbnail

Generation of Infrastructure-as-Code is fun. To be the real DevOps hero, you should build a complete CI-CD pipeline. But this is a piece of work. And if you want to deploy to multiple accounts, it gets tricky. With the new CDK, builtin pipeline Construct, it’s easy - if you solve a few problems. Here is a complete walk-through.

Spice up your Cloudformation Development life

Thumbnail

Pure CloudFormation coding only with vi can be hard work. But since CloudFormation still is the lingua franca of AWS infrastructure as code, the ecosystem keeps evolving. Even if you only use it indirectly, there are some tools to spice up your development. Hot diagrams, more aroma with compliance checks or bittersweet automated testing. Ready to taste it? Here we go.

Bridging the terraform - CloudFormation gap

Thumbnail

CloudFormation does not cover all AWS Resource types. Terraform does a better job in covering resource types just in time. So if you want to use a resource type which CloudFormation does not support yet, but you want to use CloudFormation, you have to build a Custom Resource with an own Lambda Function. CDK to the rescue: use AwsCustomResource.

Automating ACM Certificates with Serverless Framework

Thumbnail
Automating ACM Certificate creation with the Serverless Framework Encryption is the basis for secure communication in our modern world. For most web applications this boils down to using HTTPS to encrypt traffic between the client and server. HTTPS or the underlying protocols TLS/SSL rely on Public Key Infrastructure and Encryption to establish the Authenticity of the communication partner. Authenticity in this context means that the client can be sure he is communicating with Google if they access https://google.

More Tools - CDK Examples

Thumbnail

We need more CDK examples

In this github repo we focus on examples for every day work. While there are some nice examples for the fancy stuff like fargate, ecs and so on in aws-cdk-examples/typescript at master · aws-samples/aws-cdk-examples · GitHub, i felt that basic examples where missing.

So we created GitHub - tecracer/cdk-templates: Templates for aws cdk

Getting around circular CloudFormation Dependencies: S3-Event-Lambda-Role

Getting around circular CloudFormation dependencies

Several posts complain about the inability of CloudFormation to apply a Lambda event function to an S3 Bucket with an dynamically generated name.

The standard UseCase is an S3 Bucket with a Lambda event notification. In this special case the Bucket has a dynamically generated name. This cannot be done by pure CloudFormation!

How to work around this circular depency? Let me show you an easy way:
