Weekly update 24

You can become a serverless blackbelt. Enrol to my 4-week online workshop Production-Ready Serverless and gain hands-on experience building something from scratch using serverless technologies. At the end of the workshop, you should have a broader view of the challenges you will face as your serverless architecture matures and expands. You should also have a firm grasp on when serverless is a good fit for your system as well as common pitfalls you need to avoid. Sign up now and get 15% discount with the code yanprs15!

Hi, welcome to another weekly update!

New posts

Observability without breaking the bank. In this post, I took a look at Thundra’s new sampling feature and how they can help prevent observability costs from spiralling out of control. Besides the rudimentary sampling methods such as by count and time interval, they also support more intelligent modes of sampling. Such as sampling invocations that are performing poorly or erroneous.

Canary deployment with LaunchDarkly and AWS Lambda. In this post, I introduced the basics of LaunchDarkly and how you can use it to implement canary deployments for AWS Lambda. I also discussed the limitations that you need to consider, such as the number of server connections you need. Fortunately, there are ways to work around these limits. For example, by using the LaunchDarkly-relay to cache feature toggles in DynamoDB. Here‘s a CloudFormation template to run the relay with AWS Fargate.

Conferences

Since the last update, I gave the opening keynote at ServerlessDays Zurich. Where I gave a brief history of the evolution from on-premise to serverless and my views on where we are headed with serverless. The slides are available here:

I also had a great (and busy!) time at DevExperience in Iasi last week. I had two talks, a panel, a short interview and a workshop in two days… But it was worth it, and the organizers definitely went above and beyond to looked after us and cultivated a nice, sociable environment.

Upcoming workshops

Craft Conf (Budapest, May 7th) – I’m running a one-day “Production-Ready Serverless” workshop. Where we will cover the basics of AWS Lambda and the serverless framework, API Gateway, Kinesis, testing, CI/CD, configuration management, security, logging and tracing. You can register here, hurry though, there are only 3 spaces left.

I can also provide this workshop as in-house training and can do a more in-depth two-day version that gives you more hands-on experience. Details are available here.

Hi, I’m Yan. I’m an AWS Serverless Hero and I help companies go faster for less by adopting serverless technologies successfully.

Are you struggling with serverless or need guidance on best practices? Do you want someone to review your architecture and help you avoid costly mistakes down the line? Whatever the case, I’m here to help.

Hire me.


Skill up your serverless game with this hands-on workshop.

My 4-week Production-Ready Serverless online workshop is back!

This course takes you through building a production-ready serverless web application from testing, deployment, security, all the way through to observability. The motivation for this course is to give you hands-on experience building something with serverless technologies while giving you a broader view of the challenges you will face as the architecture matures and expands.

We will start at the basics and give you a firm introduction to Lambda and all the relevant concepts and service features (including the latest announcements in 2020). And then gradually ramping up and cover a wide array of topics such as API security, testing strategies, CI/CD, secret management, and operational best practices for monitoring and troubleshooting.

If you enrol now you can also get 15% OFF with the promo code “yanprs15”.
