Database Sharding Explained 🤟
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.

How Tinder built its own API Gateway 👷♂️
Tinder tried multiple solutions for API Gateway, including AWS API Gateway, Apigee, Kong and others. But in the end, they decided they really needed a bespoke solution to match their requirements of scalable, reusable and configuration-based demands. So they took Spring Cloud Gateway and built their solution on top. Find what they managed to achieve in the article in Tinder Tech Blog.

Migrating Critical Traffic at Scale with No Downtime - Part 1 👷♂️
Bringing new infrastructure to the production load is always a little risky. For Netflix which wants to ensure an uninterrupted watching experience this is a critical technical capability. In the latest blog post, they explain that real traffic replay plays a crucial role in testing new services and they built a special solution including a replay server.

Software Architecture Canvas 🍼
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!

The Inner Workings of Distributed Databases 🤟
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.

Building a large scale unsupervised model anomaly detection system 🤟
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!

2023 State of Platform Engineering Report 🍼
The word DevOps is mentioned less frequently while people speak more and more about Platform Engineering. Perforce is publishing it's report on Platform Engineering, and among many valuable insights, you will find the statement about companies underinvesting in the product managers for the platforms - because it's still a product, even for your internal developers.

Datadog long-awaited postmortem 👷♂️
Datadog had a 24 hours long outage on March, 8th. Datadog being an observability company was kinda expected to publish the postmortem soon enough, but 2 months later there was nothing published. Some researchers ever tried to write their own version, but luckily the company decided to publish the PM themselves. Read a fascinating story on how Linux upgrades can get you down even if you're deployed to 3 different cloud providers for reliability.

What Happens When You Type an URL Into Your Browser? 👷♂️
I remember several years ago I was going through an interview in Amazon. After the questions about the cloud advantages, the interviewer asked the questions in the title. And I think I managed to do pretty well: I described the 21h interruption, the events in the operating system, the DNS stuff including local caches, HTTP protocol... There was no second interview. So in case you get the same question - get the answer!

How to run a Decision-Making Architecture Board 🍼
The autonomy of decisions in team is a good thing; however if the organization just allows everybody to do whatever they want, it soon will face a zoo of technologies and approaches. So at some point it makes sense to have a board where at least those decisions can be discussed. How to create and run one? Read a guest post in the blog of Olad Zommermann!

Raft does not guarantee liveness in the face of Network Faults 🍼
Well, Raft as one of the consensus algorithms should guarantee the leader election during network faults. This post(but rather old one) showcased the 2 cases where the leader will not be able to be elected. The fixes suggested in the article as well, so take a closer look.

Hotspot performance engineering fails 🍼
Some companies believe that software can be fast, if you find some hotspots in the code and optimize those. But as an architect, you can easily guess that enormous performance problems happen from inappropriate architecture. Daniel Lemire explains it in little more detail.

Company acquisition or merging can be a tricky process from a technical perspective. Different ecosystems, programming languages, deployment and runtime approaches are among those complexities.

Effective Test Automation Approaches for Modern CI/CD pipelines 👷♂️
Unit tests are widely accepted, but do we do them right? Do we have the good test design? Do we cover all the necessary cases?

"Software design is just theory" 🍼
The question architects frequently hear is "how are you legit if you don't observe the results of your design?" and fair enough.
