AWS just announced the CloudFormation IaC Generator and added a CDK migrate command. These make it easier for you to manage manually created resources with Infrastructure as Code.
This is my first impressions of it – what worked, what didn’t and where the gaps are.
Imagine this. You have followed AWS best practices and set up a dead-letter queue (DLQ) or an OnFailure destination for every async Lambda function.
A message arrives in your DLQ. You are alerted right away because you have alarms on all of your DLQs.
You investigate the problem and determine that it was temporary and the message should be re-processed.
But now what?
You don’t need network security to keep your DynamoDB data safe. However, adding network security on top of IAM authentication and authorization is not a bad thing. Sometimes, it’s even necessary to meet regulatory requirements.
In this post, let’s see how to put DynamoDB in VPC so your data can only be accessed from within a VPC. We will look at what works best for feature teams and what works best for platform teams.
2023 has been a bittersweet year. It started with unpleasant medical news and the subsequent surgeries. The silver lining is that I did enjoy the medical leave and perhaps didn’t realise how much I needed that break! Despite several months of medical leave, I still had a productive 2023. 13 public speaking engagements 8 public …
In this post, let’s discuss a radical idea – if the API layer is not adding any value besides authentication and calling the AWS SDK, then why not just remove it and let the frontend talk to your AWS resources directly? It will be the cheapest way to build a full-stack application, and there are similar precedents in the IoT space already.
It’s not the way that I’d recommend for most of you. But it’s possible to do it safely so that a user can only access his/her data. All you need is a little bit of IAM policy and a Cognito Identity Pool.
Performing a database migration while continuing to serve user requests can be challenging. It’s a question that many students have asked during the Production-Ready Serverless [1] workshop. So here’s my tried-and-tested approach to migrating a live service to a new database without downtime. I’m going to use DynamoDB as an example, but it should work …

AWS Kinesis and Lambda are a great combo for processing large amounts of data in real-time. However, there’s a common oversight that many developers make when integrating these two services. There are established best practices for configuring Lambda’s EventSourceMapping [1] for Kinesis: Configure an OnFailure destination for failed records. Enable BisectBatchOnFunctionError. Override MaximumRetryAttempts. Choose a …

Hi, here’s a quick round-up of my November. re:Invent 2023 recap Here is the best serverless news from re:Invent 2023. Lambda Lambda scales 12x faster Each Lambda function can now burst to 1000 concurrent executions every 10 seconds, independently. It means it will take a single function just a minute to reach a peak concurrency …
A month ago, I shared how I built an affiliate tracking system in a weekend [1]. Since then, I’ve enhanced the system by integrating analytics reporting, enabling affiliates to gauge the performance of their URLs. This post will describe how the system works and why I chose Amazon Timestream over DynamoDB. How it works 1. …
