Applications nowadays are distributed as microservices all over the cloud. Organizations use Kubernetes to manage these applications at scale, which has brought great flexibility and agility for development teams. However, microservices and multicloud applications have given rise to new challenges. Now, it is harder to configure communication between distributed services and secure the data in transit.

By Jose Fernandez , Ed Barker , Hank Jacobs Introduction In November 2022, we introduced a brand new tier — Basic with ads. This tier extended existing infrastructure by adding new backend components and a new remote call to our ads partner on the playback path. As we were gearing up for launch, we wanted to ensure it would go as smoothly as possible.

Kubernetes adoption survey executive summary. Modern, cloud-native computing is impossible to separate from containers and Kubernetes adoption. While Kubernetes is still a relatively young technology, a large majority of global enterprises use it to run business-critical applications in production. The rapid adoption is driven—and challenged by—an ever-growing ecosystem of Kubernetes technologies that add advanced platform features, such as security, microservice communications, observability, s

eBPF has many uses in improving computer security, but just taking eBPF observability tools as-is and using them for security monitoring would be like driving your car into the ocean and expecting it to float. Observability tools are designed have the lowest overhead possible so that they are safe to run in production while analyzing an active performance issue.

Kubernetes is a widely used open source system for container orchestration. It allows for seamless running of containerized workloads across different environments. However, managing Kubernetes optimally can be a daunting task due to its complex architecture. Properly monitoring a Kubernetes cluster or any related environment can be difficult. Effective resource provisioning and management is a critical aspect of a Kubernetes cluster.

What I want to cover in this blog post is how I think platforms should be structured, and why it’s always plural, there isn’t one platform or one platform team.

Becoming a good engineer is about collecting experience. Each project, even small ones, is a chance to add new techniques and tools to your toolbox. Where this delivers even more value is when you can solve problems by pairing techniques learned on one project with tools learned working on another. It all adds up.

At the time of writing, 99.9% of pages on the web include at least one image. The median image-weight per page landed at 881KB in 2022 , which is more than HTML, CSS, JS, and fonts combined!

A few weeks ago, I saw a tweet that said “Writing code isn’t the problem. Controlling complexity is.” I wish I could remember who said that; I will be quoting it a lot in the future. That statement nicely summarizes what makes software development difficult. It’s not just memorizing the syntactic details of some programming language, or the many functions in some API, but understanding and managing the complexity of the problem you’re trying to solve.
