They receive early access to the articles, influence the content and participate in the closed group where we discuss the architecture problems. They also see my daily updates on all the things I am working on. Join them at Patreon or Boosty! ย 


Database Sharding Explained ๐ŸคŸ

Sharding is an important concept to ensure the reliability and performance of the overall system. You can do that in a variety of ways, which of them can cause it's own problems. Architecture Notes blog has a free post explaining in deep details what the sharding is in a nutshell. ย

Software Architecture Canvas ๐Ÿผ

I am a big proponent of Solution Architecture Documents, RFCs and ADRs. But it's always good to take a fresh look. Patrick Roos shared a new format to allow the collaborative effort to architecture: the Canvas. I especially like the strong demand for the business case(top of green) and the risks and challenges(in blue). Give it a try!

Software Architecture Canvas: A Collaborative Way to Your Software Architecture
The Software Architecture Canvas is a collaborative technique for elaborating the software architecture playground of a software initiative. With this canvas, you can work efficiently, iteratively, and in a time-saving manner on the software architecture of your software products as a team sport.


The Inner Workings of Distributed Databases ๐ŸคŸ

Alex Pelagenko begins an article with a nice analogy: he gets to the office by the bike, but if it failes - should there be a replacement? Same happens with the databases: if the first node fails, the should be a standby. But should the replication by sync or async? Should it be a master-master replication? Alex considers several databases and demonstrates the sequence diagrams how they handle disconnection issues. ย

Building a large scale unsupervised model anomaly detection system ๐ŸคŸ

Lyft leverages tons of ML models to define a wide range of parameters from ETAs to pricing. But they also need to understand if those model perform well. The problem is that different model different number of features and outputs. So they need to unify and process them efficiently. Find how they do it in the blog post!
