Weekly update 40

Hi, welcome to another weekly update.

Learn you some Lambda best practice for great good!

I have been working hard since the last update and have published 27 lessons so far (total of ~2 hours of content). The lessons cover all areas of performance & cost optimization, scalability, security and observability. The last batch of lessons will be made available when the course officially launch on the 13th Feb. Until then, you can still enjoy the special preorder price of just £9.99 (~$13).

New posts

Amazon Builders’ Library in Focus #5: static stability using availability zones. I summarised this article by AWS senior principal engineer Becky Weiss and principal engineer Mike Furr on what they mean by static stability and why each AZ should be completely independent and how it affected the design of their systems. They also discussed the importance of isolating the data-plane operations from control-plane operations.

Amazon Builders’ Library in Focus #6: implementing health checks. I summarised this article by AWS principal engineer David Yanacek on the delicate tradeoffs one have to consider when implementing a system’s health checks. It also ties into some of the concepts in #5 wrt isolating data-plane operations from control-plane operations.

Podcasts

I met up with Jeremy Daly at ServerlessDays Belfast and we sat down and recorded another episode for his ServerlessChats podcast series. It’s about an hour long, and you can listen to it here.

Talks

I delivered a new talk at the AWS Community Day Nordics in Stockholm this week. I talked about the essential open source tools that you should use as a serverless developer.

Workshops

It’s been just over 3 weeks since I announced my European workshop tour (yup, that’s what I’m calling it now…). The group tickets for the Amsterdam workshop (March 19th-20th) has sold out, but there are still a couple of early bird tickets left.

I’m also running the workshop in Helsinki and Stockholm in May. If you need help convincing your manager to let you go, I’ve also created an email template for you to use ;-) (thanks to Jeremy Daly for the idea!)
