Recently, while working on a workshop titled Testing Your Pull Request on #Kubernetes with GKE, and GitHub Actions, I faced twice the same issue: service A needs service B, but service A starts faster than service B, and the system fails. In this post, I want to describe the context of these issues and how I solved them both with the same tool.
Are you a senior software developer, architect, or engineering leader wrestling with performance bottlenecks and increasing system complexity?
This #InfoQ talk, based on Aleksey Shipilev's performance work phase diagram, reveals the critical "Performance - Complexity Curve" and how it impacts your engineering decisions and costs.

Why care about Software Design:
Software design is critical for building scalable, maintainable, and efficient systems. Good design reduces technical debt and simplifies implementation.

Scalable architectures, two concepts: 𝙎𝙘𝙖𝙡𝙚-𝙐𝙥 𝙖𝙣𝙙 𝙎𝙘𝙖𝙡𝙚-𝙊𝙪𝙩
But when to use one over the other?
In this blog post, our very own @noctarius2k, wrote about the pros and cons of each of the approaches. Simplicity and limited scalability vs complexity and higher scalability.
He also explains how simplyblock is implemented and why we did what we did

brings up a good question about Redis- one I've wondered myself: Are we using Redis the wrong way?
The main use of Redis is as a simple key/value store. The idea is that if we are doing a process such as a DB query, we can cache the result. This is essentially memoization, and I remember this being used way back with a program called memcached.
Redis is a highly optimized key/value store, but many people (myself included) use hosted Redis servers. This introduces a lot of overhead on reads.
Wouldn't we be better off moving the key/value pair server as close to the application as possible, and then relying on writes being distributes to all instances? At worst we might get old data, but if we're using the system for caching, that shouldn't matter much, and we can instead rely on eventual consistency.
I'm curious as to other's thoughts on this.
Finally got to sit and focus long enough to break open #Azure #Kubernetes services and get my new cluster deployed! Further, I was able to get it up and running and test an old Linux app on it to validate connectivity. More testing to do, but this means we’re finally gonna get to move our #K8S apps off old pre-Azure-design AKS clusters onto new ones that a.) consume our newer Azure network and governance designs and b.) actually update themselves over time

In 1983, my parents paid $299 for a 32KB memory expansion board for my TI-99/4A.
Last year, MicroCenter gave me 32GB of DDR5 SDRAM -- for free -- with the purchase of a Ryzen 7 7700X CPU.
That's just over 1 million times more memory (and it's a bit faster, too.) That's $313 million worth of TI RAM expansions cards, in 1983 dollars.
You'd need quite a few desks to support a TI system of that configuration...
For my techie friends, especially system architects: The Cloud Computer has arrived. The one you can ‘buy’ not ‘rent’ and it’s in a single crate, no external racks - with ALL the software included. True to Alan Kay’s famous maxim: If you’re going to build software, you should also build the hardware it runs on. #CloudComputing #CloudComputer #Hardware #Software #SystemArchitecture #computing #computer https://oxide.computer/blog/the-cloud-computer

How will we continue to model ever evolving techniques? How might we include them in and #SystemArchitecture #SystemsArchitecture and the concepts of sensor analytics ecosystems #SensAE and other ecosystems, especially in digital twins and #causal #DigitalTwins #CDT
When exposing an application, consider a an #APIGateway to protect it from attacks. Rate Limiting comes to mind first, but it shouldn’t stop there. We can factor many features in the API Gateway and should be bold in moving them from our apps. In this post, I’ll show how to implement authentication at the Gateway API stage.
