New Kubernetes versions are released multiple times per year, and you must upgrade your EKS cluster periodically to stay up to date. In this blog post we will go over the steps required to safely upgrade your production EKS cluster managed by Terraform. At Blue Matador, we use Terraform to manage most of our AWS infrastructure, and our EKS cluster is no exception. We use the eks module, which provides a lot of functionality for managing your EKS cluster and worker nodes.

Today managing your licenses with Cloudsmith has become incredibly simple. Now, with the help of our License Compliance UI, not only can you update the license associated with a package without needing to modify a package, plus you can also view statistics of how your overall licenses appear across all packages within a repository. Don't believe me?

Kubernetes is an open-source platform for container orchestration. You can use it to deploy a highly resilient, self-healing infrastructure using automation and infrastructure as code (IaC). Kubernetes includes features for zero downtime deployments, scaling, automatic rollout and rollback of updates, and service discovery. Kubernetes is designed to help you manage container deployments at scale via REST API.

An infrastructure, especially if it is scalable, can become extremely complex to visualize and observe. If something goes wrong, it would be difficult to fully understand the problem without a great data monitoring strategy. Information related to CPU, RAM, and statistics about SSH or HTTP servers are critical to understanding the performance of your web-application.

There are tons of query languages. Yet, another query language was invented: the StackState Query Language, or STQL for short. Perhaps this raises some questions. Such as: Why did we not choose to implement SQL? Did we reinvent the wheel? How did we balance the complexity of the language against the time to implement the language? What's the learning curve of this new language? Let me share with you our novel approach.

In an era where container technologies have taken the industry by storm, one of the most common online searches on the topic of containers is ‘Kubernetes vs Docker’. The relevance and accuracy of this comparison is questionable, as it is not really comparing apples to apples. In this blog post, we will attempt to clarify both terms, present their commonalities and differences, and help users better navigate the ever-growing container ecosystem.

As many organizations migrate to the public cloud, a major concern has been how to best secure data, preventing it from unauthorized access or exfiltration. Deploying a product like HashiCorp Vault gives you better control of your sensitive credentials and helps you meet cloud security standards.
