Prelude Hi guys, after a series of back-to-the-future-I-didn’t-have-time-to-write-new-things… I’m back. What happened in the last months… ok, covid19 put the whole world in trouble, I bought an apartment, I opened a company and I resign my contract. Really. Nothing. Special. But TODAY - I wanna talk about a project I have since a while, and I worked on a boring Sunday afternoon: I hacked my blog to let Polly read it for you!

Introduction In the last two weeks, I released a few CDK stacks: I made some experiments around API Gateway and service integration that came out in two serverless forms, the Contact Form and the Upload Form, read to be deployed in your static web page 😎. Actually, with CDK you can do so much more and so much more easily. The last stack I released - a producer-consumer chain presented here - it was a way I used to introduce how you can leverage Typescript inheritance to recycle an old stack and build on top of it.

Introduction A few days ago I wrote about a simple stack that leverage API Gateway and Lambda-proxy integration to create a safe upload endpoint to let unknown users push inside a bucket of your choice. The stack I will present today is can be used to build a producer-consumer chain, by implementing the SQS Extended pattern you can find in AWS exams. For the most curious, here you can find the core code.

Introduction The AWS CDK is becoming day by day pretty easy to use. I use Typescript, and today I will talk about a common use case: a simple Upload Endpoint for your API Gateway than like a LEGO can be built with a few instructions and of course…without the need of any server. For the most curious, here you can find the core code. Scenario You want to provide an endpoint to upload object: where?

Introduction Hi everybody, thanks for the claps, it was a great month - rain rain rain again - now I’m back. The only GOOD THING of this terrible May is that AWS CDK came to simplify our life and I started using it (just a little) bit - still, enough to say, sincerely: it’s awesome. I used the Typescript version, everything is broken 2 release out of 3 but the time you save exploring the interfaces instead of looking for Cloudformation documentation online worths the time spending in troubleshooting the ongoing changes.

Introduction Recently I worked with AWS Lambda and API Gateway to extend my set of personal APIs and collect information from several sources. I wrote an article on that (if you want to have a look). In this article I will talk about the AWS Step Functions service that enable create finite states machines to easy coordinate the components of distributed applications and microservices using visual workflows. Why AWS Step Functions?
