100 Days of Swift – Day 55 – Hacking with Swift hackingwithswift.com

Highlights

          Yes, you might decide making games is what you want to do on iOS, and maybe you’ll even be lucky enough to get into Apple’s Arcade program. Of course, you’re also just as likely to decide that your goal is to make apps, but even then the skills you learn making games will prove useful.

Distributed architecture concepts I learned while building a large payments system - The Pragmatic Engineer blog.pragmaticengineer.com

Highlights

The two most common scaling strategies are vertical or horizontal scaling.

          Vertical scaling is basically "buying a bigger/stronger machine" - either a (virtual) machine with more cores, more processing, more memory. With distributed systems, vertically scaling is usually less popular as it can be more costly than scaling horizontally.
        

          A straightforward way to get our availability number is to add a bunch of these machines/nodes into a cluster.
        

          For many systems, the four nines availability (99.99%, or about 50 minutes downtime per year) is considered high availability.
        

          Systems usually have a lot of noisy requests, hence the p95 and p99 latencies are more practical usage in the real world.
        

          To make sure we build the right thing, a system that is "better" than it's predecessor, we used SLAs to define expectations.
        

          Horizontal scaling is about adding more machines (or nodes) to the system, to increase capacity. Horizontal scaling is the most popular way to scale distributed systems, especially, as adding (virtual) machines to a cluster is often as easy as a click of a button.
        

          Before diving into planning a system, I have found the most important thing to decide what a system that is "healthy" means. "Healthy" should be something that is actually measurable. The common way to measure "healthy" is with SLAs: service level agreements.
