Kubernetes is a complicated beast in many respects, and monitoring is no exception. Although in some ways the monitoring tooling and strategies that teams already have in place can be extended to support Kubernetes, in other ways Kubernetes requires you to forget everything you think you know about how APM is supposed to work. To

In the public cloud, “design patterns” have emerged as a popular concept for defining cloud strategies tailored to specific use cases or goals. Microsoft offers a series of design patterns for Azure, for example, and practitioners have adopted similar strategies for AWS. To date, however, there has been less discussion of design patterns for private

Over the past few years, organizations looking to build private clouds have gained some interesting new options in the form of Azure Stack and AWS Outposts. At the same time, OpenStack remains an important contender in the private cloud ecosystem. Understanding the strengths and weaknesses of these three platforms is critical for deciding which solution

Today’s private clouds must accommodate a range of new needs and use cases that the private clouds of the past rarely contended with. At the same time, new technologies (or old technologies that have matured) have created novel opportunities for building out hybrid clouds. For both of these reasons, redefining private cloud architectures is one

Like many computing systems, your Kubernetes environment requires the use of sensitive information. Sensitive values (such as passwords, SSH keys, and security tokens) are referred to collectively as secrets. In this article, we will explain how to store and manage the secrets in your Kubernetes environment, and we will examine the capabilities of Kubernetes and

Kubernetes deployments can scale to support services and applications that run in a broad array of environments, from multi-cloud deployments to resource-constrained edge computing environments. But as businesses look to save money by optimizing infrastructural resources, the process of deploying thousands of microservices over geographically distributed servers can become increasingly complicated. If your company will

Kubernetes is widely recognized as a platform that enables highly efficient use of infrastructure, but organizations need to understand those benefits are maximized when the developer experience itself is optimized. Developers are increasingly assuming responsibilities for systems operations. In the past, it was common to have a separate team of systems administrators responsible for deploying

One of the things that makes Kubernetes so powerful is that it can run virtually anywhere: On bare metal servers and virtual machines, on-premises or in the public cloud. (These are overlapping categories to an extent, because an on-premises cluster could be hosted using bare-metal servers or virtual machines.) Yet the fact that Kubernetes can

High Availability (HA) and uptime may be similar concepts, but they’re not the same. Availability refers to how accessible your server is or how many people can connect to it; while uptime is about whether your server is even reachable. What this means is that if even a single connection to your server is possible,

When it comes to Kubernetes clusters, size matters. The number of nodes in your cluster plays an important role in determining the overall availability and performance of your workloads. So does the number of namespaces, in a way. This does not mean, however, that bigger is always better. A Kubernetes cluster sizing strategy that aims

Just as there are many parts that comprise Kubernetes, there are multiple ways to go about Kubernetes deployment. The best approach for your needs depends on your team’s technical expertise, your infrastructure availability (or lack thereof), your capital expenditure and ROI goals, and more. There are multiple ways to scale a Kubernetes environment to meet

Containers and cellular networking are not usually part of the same conversation. Although both are important technologies, the use of containers in the cellular and telco space has been fleeting, so far. But that could change thanks to the challenges posed by the rise of 5G networks. In several respects, containers are the perfect solution
