Engineering Growth Framework from Medium

I recently started a new role, and one of the first things I’ve been looking at is career ladders (aka job rubrics), org structure, and performance reviews (a.k.a. talent reviews or growth frameworks).

In that vein, the Medium Engineering team’s “Growth Framework” was recommended to me, so this is a quick summary of it.

TLDR; Medium have a “Growth Framework” for recognizing and developing their team that uses 4 categories (Building, Executing, Supporting, Strengthening) each with 4 tracks. Each track has 5 increasingly difficult to achieve milestones, and each level of milestone has points associated with it. The more points you have, the higher your level, which translates into job titles. Whew! It is a complex system, and while perhaps more complex than many (especially smaller) organizations need, it is none a very interesting framework which many might use as a reference. The tracks, milestones and examples in particular can be useful inspiration when putting together your own career guides.

Blog post summary: Automating safe, hands-off deployments at AWS

AWS’s Clare Liguori wrote an excellent blog post on Automating safe, hands-off deployments.

This is a summary (1,700 words, vs 5,300 in the original) and mostly just a copy & paste of highlights. I have also skipped some of the sections that are at scales larger than most folks deal with (e.g. global releases across 26 regions!).

Blog post summary: Domain-Oriented Microservice Architecture at Uber

Domain-Oriented Microservice Architecture at Uber” is a blog post on the Uber engineering blog. There were some comments about the post not giving credit to prior art, which I think is fair, but it is a useful post none the less. Uber provide an interesting approach to classifying and organizing their (2,200!) microservices, by using the concepts of Domains, Layers, Gateways and Extensions.

This is a shortened version here (1,200 words, vs 3,800 in the original), since I tend to learn by creating summaries, but it is mostly just a copy & paste, so check out the original with diagrams etc if you’re really interested.

Development and delivery practices for team success

Most metrics for measuring developer productivity, such as lines of code or issues closed, are notoriously ineffective. But the research in the excellent State of Devops report shows that, rather than focusing on local metrics and individual developer performance, it is better to look at overall development and delivery practices. Specifically, there are metrics that predict and reflect a team’s ability to successfully deliver working software into production, including deployment frequency, and the mean time to restore service after an incident. This articles discusses why some metrics are useless, and takes a closer look at the recommendations in the 2019 State of Devops report.

This is an abridged version of The Accelerate State of DevOps Report 2019; essentially a cut and paste of the most salient parts. The original is about 18,000 words; This is about 2,500 words.

File, Block and Object Storage

I was in an AWS class today, where they were talking about S3, and how it is “object storage”. But what does that mean? One way to explain it is to contrast it with other types of file storage, namely File and Block Storage.
