How container networking works at Platform.sh
Posted on November 2, 2023, Level intermediate Resource Length medium
We'll take a look at how we wire (most of) it up. In particular, we'll go over the role of the Platform.sh edge layer, and describe in detail how we network hosts and containers together. From the networking perspective, our job is to make sure that a request directed towards your web server reaches the right container, and that container is able to communicate with other containers that your hosted application depends upon, all while making sure that someone else's container cannot talk to one of your containers.

How IKEA Retail standardizes docker images for efficient machine learning model deployment
Posted on October 22, 2023, Level beginner Resource Length long
What do Docker and IKEA Retail have in common? Both companies have changed how products are built, stored, and shipped. In IKEA Retail's case, they created the market of flat-packed furniture items, which made everything from shipping, warehousing, and delivering their furniture to the end location much easier and more cost effective. This parallels what Docker has done for developers. Docker has changed the way that software is built, shipped, and stored, with Docker Images taking up much less space "shelf" space.

Distributed cloud-native graph database with NebulaGraph Docker extension
Posted on May 4, 2023, Level intermediate Resource Length medium
Graph databases have become a popular solution for storing and querying complex relationships between data. As the amount of graph data grows and the need for high concurrency increases, a distributed graph database is essential to handle the scale. Finding a distributed graph database that automatically shards the data, while allowing businesses to scale from small to trillion-edge-level without changing the underlying storage, architecture of the service, or application code, however, can be a challenge.
