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. By Mohammed Ajmal Siddiqui.

The article deals with:

• What Platform.sh looks like
• Overlay networks
• Our ARP rig
• The Platform.sh ARP Daemon

To sum up, Platform.sh encode the IP of the physical host housing the container within the container IP, and run their own ARP daemon that computes the grid host IP based on the container IP on demand in order to serve the ARP cache of the kernel. Interesting read!

SQL (Structured Query Language), as you probably, know, helps you collect data from databases. It is specifically designed for that. In other words, it works with rows and columns, allowing you to manipulate data from databases using SQL queries. By Nate Rosidi.

The article focuses on:

• Why Do We Need SQL Query Optimization?
• SQL query optimization techniques
  • Use SELECT With Specified Fields Instead of SELECT ‘*’
  • Avoid Using SELECT DISTINCT
  • Avoid using loops
  • Use wild cards properly
  • Use top or LIMIT to limit the number of sample results
  • Use indexes
  • Bonus section: Use SQL query optimization tools

Due to the complexity of long codes and highly complex queries, you might consider using query optimization tools. You will find a list of tools together with small explanation for each of them at the end of the article. Nice one!

We helped a customer recently who was storing 500 million chat messages in a single Postgres table. As the table was growing, their queries were slowing down. By Michel Pelletier.

The simple solution we offered was table partitioning. The difficulty was creating the partitions and migrating the data without blocking queries and downtime. This post explores the method we used to solve this - Dynamic Table Partitioning.

Further in this article:

• Why Partition Data? The large table problem
• Starting small but getting big
• Dynamic partitioning with pl/pgSQL
• Creating parent tables
• Creating dynamic child tables
• Progressively copying data from the large tables
• Setting up a daily cron job to create partitions

While there is some complexity, I hope this example has given you some ideas on how you too can partition your data for optimal query performance. Nice one!

Nginx is one of the best popular webservers today. Its popularity is due to the fact that it is very fast and easy to set up. Other side of this popularity - nginx is often being a target of malicious attacks. So, if your nginx is not limited by available resources, your server may totally “fall” when nginx spent all system resources. That’s why you should control and limit resources Nginx consumed. By Vyacheslav Breus.

All limits are sets in nginx configuration file. The article gives a good advice on:

• Global settings
• Disk operations
• Compression and caching
• Security settings

In this article author described how to optimize your nginx works and gave some advices about base security improvements. Nice one!

This guide shows how to bring up a Raspberry Pi Zero, Zero W, or Zero 2 W without needing to attach a keyboard/mouse/monitor. For older Pi OS releases, basic settings can be configured by editing text files directly on the SD card using an editor on your main PC prior to first boot. For newer Pi OS releases, the rpi-imager tool can be used to both burn the OS image and configure settings. By Carter Nelson.

In this super detailed guide you will find:

• How to run a sanity check to verify if the Pi Zero is OK
• Install OS on to SD Card
• Text file editing
• Using rpi-imager
• Suggested initial setup

… and more. Plenty of screenshots and every step is well explained. Nice one!
