Lambda and Kinesis - beware of hot streams

Back in 2017, I wrote a post titled “3 pro tips for Developers working with Kinesis streams”, in which I explained why you should avoid hot streams with many Lambda subscribers. When you have five or more functions subscribed to a Kinesis stream you will start to notice lots of ReadProvisionedThroughputExceeded errors in CloudWatch.

SLO, SLA, SLI Oh My! Creating them can be easy

Imagine you are driving a car on a freeway. Your speedometer is telling you you’re going 62 mph. But you “gotta go fast”. Faster than then 65 mph speed limit. So you go for it: first 68mph, then 75mph, then 80mph. Then you pass a police officer hiding in a speed trap. To your dismay, they pull you over and give you a ticket. All is not lost: there is a silver lining here. It’s the perfect analogy is to understand how indicators, objectives, and agreements all work with each other.

AKS Cluster Performance: How to Better Operate Kubernetes in Azure

AKS is the managed service from Azure for Kubernetes. When you create an AKS cluster, Azure creates and operates the Kubernetes control plane for you at no cost. The only thing you do as a user is to say how many worker nodes you’d like, plus other configurations we’ll see in this post. So, with that in mind, how can you improve the AKS cluster performance of a service in which Azure pretty much manages almost everything?

K8s: Why it’s time to ditch legacy debugging

Kubernetes is a highly distributed, microservices oriented technology that allows devs to run code at scale. K8S revolutionized cloud infrastructure and made our lives a whole lot easier in many aspects. Developers don’t have to do anything but write code and wrap it in the docker container for K8S to handle. But even its greatest enthusiasts will admit debugging Kubernetes pods is still a pain.

Chef automation for infrastructure management

Infrastructure management has come a long way. (Mostly) gone are the days of manual configurations and deployments, when using SSH in a “for” loop was a perfectly reasonable way to execute server changes. Automation is a way of life. Configuration management tools like Chef, Puppet, and Ansible — once on the bleeding edge — are now used by most enterprises.

DevOps Release Management Best Practices

Because DevOps practices can bring great speed and reliability to the software delivery lifecycle, release management can seem daunting. But, the improved visibility and collaboration brought about by DevOps can also help with the release management process. While the general concept of release management doesn’t really change between ITIL (IT Infrastructure Library) and DevOps, there are a few ways that the process differs.
