If your organization is looking for DevOps professionals, then here’s what to look for in order to spot the right individuals — and weed out the wrong ones.
What i’d like is to see an article on companies that are DevOps fakers, either as hiring employees or as suppliers of DevOps services. 🙂
Here are some lessons learned from all the experiments above:
Be prepared for 1-3 seconds cold starts even for the smallest Functions
Different languages and runtimes have roughly comparable cold start time within the same platform
Minimize the amount of dependencies, only bring what’s needed
AWS keeps cold starts below 1 second most of the time, which is pretty amazing
All cloud providers are aware of the problem and are actively optimizing the cold start experience
It’s likely that in middle term these optimizations will make cold starts a no-issue for the vast majority of applications
More interesting data on serverless…
All providers seem to struggle with delivering constant performance, especially when concurrency comes into play. Overall AWS Lambda seems to have the best performance, mainly because of the reasonable overhead, which makes other providers pretty much unusable for applications with concurrent requests. Maybe AWS Lambda still has the competitive edge, because it started 2 years before the other services. Overhead is an important size for all kinds of requests, not only compute intensive workloads, 3 seconds of additional overhead (Looking at you, Azure) may kill the user experience.
There are tech skills and there are soft skills. Every programmer knows that. Tech skills are about algorithms, operators, classes, objects, and everything else they teach us in tech schools. Soft skills are about something else. What exactly? Difficult to say. Let’s try to clear the air.
A great list of real soft skillz 🙂
Something to think about…
If your job satisfying?
Yes, Yes, awesome.
Loads more to read on this page and linked pages 🙂
Some good visualisations of DevOps. People always like pretty pictures. 🙂
