Key Metrics for Monitoring Google Cloud App Engine

Google Cloud App Engine is a serverless platform that enables users to develop and deploy applications. App Engine allows developers to focus more on building applications and less on managing infrastructure. Even though you don’t have to worry about maintaining any underlying infrastructure, you do have to ensure that you have enough visibility into App Engine health and performance to proactively prevent downtime.

Node.js Performance Tuning and Testing

We know Node.js for its lightning-fast performance. Yet, as with any language, you can write Node.js code that performs worse for your users than you’d like. To combat this, we need adequate performance testing. Today, we will cover just that with an in-depth look at how to set up and run a performance test and analyze the results so you can make lightning-fast Node.js applications.

Several US government websites are now inaccessible after TLS certificates expire during the shutdown.

In a government shutdown all that is considered non-essential stops. As we can see now, renewing the TLS certificates is obviously non-essential. Reportedly, more than 80 TLS certificates have expired, leaving dozens of government-related websites inaccesssible. The Department of Justice, NASA and the Court of Appeals are among the sites that have been affected. Important services have been impacted because of this as well, including payment portals.

Why I love containerd...and Docker!

I talk a lot about containerd. I write blog posts about it, speak at conferences about it, give introductory presentations internally at IBM about it and tweet (maybe too much) about it. Due to my role at IBM, I’ve helped IBM’s public cloud Kubernetes service, IKS, start a migration to use containerd as the CRI runtime in recent releases and similarly helped IBM Cloud Private (our on-premises cloud offering) offer containerd as a tech preview in the past two releases.
