Just Use Postgres for Everything 👷♂️
Typical startup software system will include caches, queues, different databases(supplied.eu is no exception). But is this the only way? Stephan Schmidt is arguing that you can pick just postgres for all of that with the appropriate configution accompanied by required extension. See the list inside.

Architecting for fast flow 👷♂️
Everyone wants to move fast, but few knows how architecture can support this. Bug part is DevOps practices and organizing teams accoring to Team Topologies; second part is the software architecture itself. This presentation in particular explains what you want from a modular monolith to have a fast, sustainable pace in the long run

How to build a PaaS for 1500 engineers 👷♂️
At Bolt we have Foundation team which provides the CI/CD services, runtimes, common libraries and other stuff. The problem of theirs was always communicate the value they bring to the business. This article can help you find what you should and should not compare your platform team with and how to think about value of the platform team

Projects considered harmful - Part 1 🍼
The first thing you get to know about project management is the triangle of budget, scope, time - pick any two. Uwe got an interesting perspective on it, where the project manager’s triangle that visualizes clearly what tends to happen. In this triangle, quality replaces budget as an axis and budget becomes the triangle’s perimeter. Follow for more details

Degradation vs disruption 👷♂️
Do you know the difference between service degradation, disruption and outage? Well, this article explains it well alongside with SLAs, Blast Radius and what's the most important: the business consequences

AWS open-sourced Secrets Manager Agent: what does that mean? 👷♂️
Typically to access a secret you would call AWS Secret Manager, which will bill you per invocation and contribute to your cloudbill. AWS open-sourced the Secret Manager Agent which you can now run as a side car and cache the secrets with the eviction policy automatically allowing for reduced cost, improved conveniece and fine-grained access control. Good stuff!

Software is not art anymore 🍼
Why companies hiring React developers instead of FinTech developers? How to understand if you need to search for a quick solution or actually study the problem? Do you remember the time without clouds? Dylan Beattie and I answering those questions with tons of stories in the interview. Grab a snickpick!

How Grafana used Dapr to improve vulnerability scans 👷♂️
If you're buidling containers using 3rd party dependencies, you have to protect yourself from supply chain attacks. It might seem as easy as running a scan against a container only to discover later that scale makes things complicated. You need to add several sources of scanning requests, cache results for performance, handle errors. Grafan tried to solve it using Dapr engine, find what they designed.

Evolving the Backend Storage for Platform Metrics 👷♂️
Heroku stores and analyses metrics for it's client for enabling features like auto-scaling. A whole subsystem called MetaaS or Metrics-as-a-Service is designed specifically for this task, including Apache Kafka and Cassandra. While there are no issues with Kafka, operating a Cassandra cluster proved to be tedious. The team decided to migrate data to DynamoDB and after a year, made a conclusion it was the right choice. Find the reasoning inside.

QA myth busting: Quality can be measured 🍼
Testing NFRs is part of an architects job, and another part is to correctly interpret the results. Having the goal of having low coupling or low cyclomatic complexity can screw over your product. Vitaly Sharovatov explores the nature of metrics in QA and explains the proper attitude to them in this longread.

The Importance of Using a Composite Metric to Measure Performance 👷♂️
To follow up on the metrics, let's consider an example of Indeed: they provide different scenarios of a client web page and demonstrate that you can not possible use a single metric to make a conclusion if the page was slow or not. Instead you need to use a compound metric for a more holistic picture.

Discord's Streaming Technology 👷♂️
Discord is a popular chat app with the group calls functionality. Discord also is relating to gaming, so streaming games on a call was a natural necessity. In their engineering blog they describe how the stream is coordinated between client apps and Discord servers, how WebRTC helps making it happen and how the performance is measured.

Kubernetes resiliency (RTO/RPO) in Multi-Cluster deployments 👷♂️
Main disaster recovery objectives are Recovery Time Objective - how much times it requires to get back up and Recovery Point Objective - how much data we are losing during the disaster. Kubernetes though with the StatefulSet feature can be considered a tool to achieve Zero RTO for single-cluster resiliency. Multi-cluster is a bigger challenge. Find what's about it in the article by Avesha.

Fault-tolerant Distributed Transactions Can be Fast and Simple 🤟
There is a paper a new Unanimous two-phase-commit protocol which is used by Spanner, MongoDB, Yugabyte and others with conjuction of Paxos. This pair though requires double N plus 1 nodes to tolerate N failures(so 3 nodes for a single node failure), and U2PC claims to require only N+1. Murat digs deep into the paper in his blog post.

Is the Serverless Fairytale over? 🍼
Serverless as a term is roughly 10 years old - at least Lambda was released in 2014. However SQS was there ever earlier, as well as App Engine. What do we see there after more than a decade? And is it even a trend outside of AWS conferences? Huge longread on the understanding serverless and what it expects next.

Digital Bank Case Study by Monzo 👷♂️
Did you know that Mastercard and other payment providers do not offer cloud integration, so you need to have a data center as a digital bank? Or that you can build payments store on Cassandra? Monzo, a digital bank in UK with 4+ millions of customers, have their case study published, and this article provides a good overview.

PostgreSQL Index Types 🤟
PostgreSQL supports 6 index types including B+Tree, Hash and GIN. You would want to use different types of indexes for various column types, B+Tree works well for auto-incremented keys, while GIN index is better suited for json fields. Vlad Mihalcea got a great writeup about index types in PostgreSQL.

Rate limiting as security tactic 🍼
Rate limiting is considered as a performance practice in the first place, basically implementing control demand. At the same time, it is also a way of safeguarding your apis and making at available and secure. Find the whole consideration in the Red Hat blog.

TDD Can not work 🍼
A little provocative, right? Typically people argue if TDD works in particular situations, or to best apply the approach, but this piece discusses if it can theoretically work. And they have some solid reasoning! Find out the argument inside

Architecture Weekly #124
Today the majority of the articles are somehow related to the Serverless. We start with cloud cost report by Datadog, Architecture Decisions in Database-as-a-Service Neon and the interview about Thinking Serverless. We also touch on Serverless Fairy - is it over yet? Follow the issue below!
Highlights
State of Cloud Costs 🍼
Did you know that 54% of cloud container cost is spent on idle time? Does it mean it would be better spent with lambdas - not necessarily, but sparks a question indeed. This, and several more insights about the structure of cloud costs in the corresponding report by Datadog

Architecture Decisions in Neon 👷♂️
Neon is Database-as-a-Service, offering Managed Postgres. Not only they have interesting opinions on DB technology(Just use Postgres by default), they also share great insights how to provide a reliable, scalable database cluster. This is exactly what their article is about.

Thinking Serverless with Luca Mezzalira 🍼
Serverless is not merely a way how to run code in cloud; it is a paradigm and mindset shift from technology and infrastructure into business problem and components to solve it. Luca Mezzalira, a Principal Serverless Specialist at AWS tells how to think about Serverless for the best decision making during system design
