If you're on Spain's regulated electricity tariff (PVPC), timing is everything.

In a previous post, I explained how to connect AWS Step Functions to a private API Gateway endpoint thanks to the new integration with AWS PrivateLink and Amazon VPC Lattice.

At Re:Invent 2024, AWS announced EventBridge and Step Functions integration with private APIs.

Last November 2024, I attended an AWS user group meetup in Barcelona.

AWS Step Functions introduced two new features: variables and support for JSONata.

At re:Invent 2023, AWS announced a new feature for Step Functions that allows you to call third-party HTTPS API endpoints directly from your workflow without the need to write a Lambda function.

Security is a very important topic for all cloud engineers.

I recently came across David Boyne's blog post: How to Observe EventBridge Events with Postman and WebSockets.

In this article, I will discuss a few tricks on how to optimize your GraphQL API for items that use composite keys in DynamoDB.

In this post, I will teach you how you can handle many-to-many relations with AWS AppSync, how to avoid denormalization and still avoid the n+1 problem.

If you have been working with DynamoDB, you are probably quite familiar with the notion of Partition Keys and Sort Keys (aka PK and SK).

CloudFormation is an AWS service that allows you to maintain Infrastructure as Code (IaC).

DynamoDB is a fully managed NoSQL database that delivers single-digit millisecond performance at any scale.

✏️ Edit - 2023-04-11: If you're interested in creating JavaScript resolvers with TypeScript rather than utilizing Lambda functions, check out this alternative article.

AppSync is a fully managed service from AWS that lets you build and deploy scalable and secure GraphQL APIs in the cloud.
