When working with containers in Kubernetes, it’s important to know what are the resources involved and how they are needed. Some processes will require more CPU or memory than others. Some are critical and should never be starved. Kubernetes defines Limits as the maximum amount of a resource to be used by a container. Requests, on the other hand, are the minimum guaranteed amount of a resource that is reserved for a container.
Content Learning how to monitor the Kubernetes API server is crucial when running cloud-native applications in Kubernetes environments. The Kubernetes API server can be considered as the front end of the Kubernetes control plane. Any interaction or request from users or internal Kubernetes components with the control plane go through this component. Ensuring you monitor the Kubernetes API server properly is of vital importance to ensure your Kubernetes cluster works as expected.
Sysdig is pleased to announce that we’ve achieved the Amazon Linux 2022 Ready designation as part of the Amazon Web Services (AWS) Service Ready Program. Amazon Linux 2022 (AL2022) is the newest Linux operating system from AWS available to support your workloads running on Amazon EC2. The team at Sysdig validated AL2022 with Sysdig Secure and Sysdig Monitor to ensure full support for our container security and cloud-native monitoring capabilities with this latest OS.
Observability in serverless computing environments, such as AWS Lambda, has always been a challenge.
Many of the benefits of running Kubernetes come from the efficiencies that you get when you share the cluster – and thus the underlying compute and network resources it manages – between multiple services and teams within your organization. Each of these major services or teams that share the cluster are tenants of the cluster – and thus this approach is referred to as multi-tenancy.
Users live in the sunlit world of what they believe to be reality. But, there is, unseen by most, an underworld. A place that is just as real, but not as brightly lit. The Kernel Parameter side (apologies to George Romero). Kernel parameters aren’t really that scary in actuality, but they can be a dark and cobweb-filled corner of the Linux world. Kernel parameters are the means by which we can pass parameters to the Linux (or Unix-like) kernel to control how that it behaves.
October has, as usual, been a busy month, and Sysdig announced many new features. In Sysdig Monitor, we announced the release of four new Advisories and Yaml config support for Advisor. In Sysdig Secure, we released Severity filtering in Insights, Pod and Node activity view in Insight and four new Falco rules added to the Rules Library. Each of these are discussed in detail below.
My father worked with some of the very first computers ever imported to Italy. It was a time when a technician was a temple of excellence built on three pillars: on-the-field experience, a bag of technical manuals, and a fully-stocked toolbox. It was not uncommon that missing the right manual or the correct replacement part turned into a day-long trip from the customers’ site to headquarters and back.
