Architecture Weekly Issue #29. Articles, books, and playlists on architecture and related topics. Every record has the complexity indication: 🀟 means hardcore, πŸ‘·β€β™‚οΈ is technically applicable right away,  🍼 - introduction to the topic or an overview. Now in telegram as well.


It's already been 165 days of the crazy, brutal, unjustified war of Russia against Ukraine. We condemn this war and want it to stop ASAP. We continue this newsletter so you can advance your skill and help the millions of Ukrainian people in any way possible.

100% Availability Trap 🍼

Amount of people believing you can reliably have service 100% available is surprisingly high. Uwe Friedrichsen shares his take on why it happens, the consequences in our systems and what to do about it.

A widespread fallacy

Strict-serializability, but at what cost? πŸ‘·β€β™‚οΈ

Murat published a surprisingly clear blog piece - this time on the cost the system has to pay for the strict serializability. It starts with describing what is difference between linearizability and serializability and what guarantees they provide. In the end, Murat asks, does business really need that strictness at the implied cost?

Strict-serializability, but at what cost, for what purpose?
Strict-serializability guarantees that transactions appear to occur in an order consistent with the β€œreal-time” ordering of those transactio...

Kubernetes Operator Pattern πŸ‘·β€β™‚οΈ

Kubernetes runs tons of payloads for many companies across the globe. In order to control custom resources like databases, externals VMs etc, there is an Operator pattern, that you can apply. Read further what it is precisely and how to create one.

Complicated Automated Tests πŸ‘·β€β™‚οΈ

Live Streaming Reference Architecture on AWS πŸ‘·β€β™‚οΈ

One of the domains you can stumble upon is live streaming: creating video and distributing it to the subscribers in real-time. The task is pretty complex given you need to handle different bitrates, edge latency, security and other aspects. AWS has a reference architecture on it, but be aware: it uses a lot of hosted services, so if you decide to build your own, you will need to replace them.

Data Types and Algorithms for Convergence  🀟

Last time there was a link to a CRDT article. This time we include a short note from Martin Kleppmann on data types which can be used for convergence: basically the eventual consistency contrary to the consensus.

CD at Lyft πŸ‘·β€β™‚οΈ
