Consistent hashing

Slicing and dicing data There’s many ways to distribute our data over multiple nodes. Some prefer to partition their data vertically instead of horizontally and vice versa. Lets briefly explore the difference to give some of our readers that are new to these concepts an idea of what we are talking about. Horizontal partitioning When you are partitioning a table horizontally we typically refer to the art of dividing a table into subsets of rows that are stored in seperate nodes....

What is a container?

In this article I want to provide you with a simple abstract in order for you to discover the container paradigm yourself. We’ll try to answer questions like: what are containers, how are they made and why are they great?

First things first, containers are not VMs....

Going global with KMS and Secrets Manager

In this post I want to give you a brief introduction on how to deploy KMS keys and secrets in Secret Manager across multiple regions. We’ll do so by making use of replication to minimize waste and prevent repetition. Multi-region KMS key July last year AWS introduced multi-region KMS keys. A new capability that lets you replicate keys from one region into another. With multi-region keys, you can more easily move encrypted data between regions without having to decrypt and re-encrypt with different keys in each region....

Lets talk about latency based routing in AWS

Distance affects performance, going further away latency can easily reach a third or half of a second for a round-trip. This could be a bummer when you serve customers globally. Luckily there’s.. Global Accelerator Global Accelerator solves a few common DNS problems1 as it’s not relying on IP address caches. It has 2 static IPv4 addresses as a single entry-point for users to connect through and there’s no DNS configuration for you to maintain....

Agile Shower Thoughts

Right of the bat I want to point out that this article isn’t directly applicable to start-ups, where things have to be built from the ground up. But where there is steadiness and stability, a mindset that prioritizes shipping features with urgency can cause a lot of problems down the road. I think that software delivery is preferably a 3 step process that does not involve rushing features to market. Lets talk about that, and how we can iterate faster and be more efficient....
