Containers vs Virtual Machines (VMs)

As microservices gain in popularity, containers have become a hot topic for developers. But how do they differ from virtual machines? Will containers replace virtual machines? And when should you choose containers over virtual machines? When it comes to defining virtual machines, the name says it all – machines (servers or desktops) that have been virtualized.

New LM Container, Argus, and Kubernetes Developments

LogicMonitor recently released LM Container Argus v4 and has made monitoring Kubernetes clusters even easier. We have updated our Add Kubernetes Cluster wizard to make customization easier in the installation process. Start by going through the normal configuration settings, and then you will have the option to edit additional configuration settings to the CollectorSet Controller and Argus YAML files.

November Meetup - GitOps with Rancher Continuous Delivery

As the number of clusters under management increase, application owners and cluster operators need a programatic way to manage deploying to their clusters. Rancher Continuous Delivery allows an administrator to create groups of clusters and link them to Git repositories. This means an application owner only ever needs access to the Git repository and not the management cluster. Deployment manifests can be defined in Helm, Kustomize or K8s yaml files and can be tailored based on attributes of the target clusters.

September 2020 Online Meetup - What's New with K3s?

If you haven't heard, Rancher's K3s was accepted last month as a Sandbox Project by the CNCF! Exciting things have been underway with K3s and in this September's meetup we will bring you up to speed on all of them. We’ll discuss the donation of K3s to the CNCF and talk about the changes you can expect to see as part of this move. Rancher experts will also cover the features and enhancements available in the 1.19 release. The focus of the 1.19 release has been improved configurability and operations for K3s clusters.

Rancher Online Meetup - December 2020: Open Source Hyperconverged Infrastructure

Learn about a new project we’ve been working on at Rancher Labs! Harvester is a virtualization and HCI platform that uses open-source hypervisors and other CNCF technologies to produce a seamless experience for administrators of complex environments that depend on Virtual Machines. Join Harvester’s principal engineer Sheng Yang and product manager William Jimenez as they walk you through the new tech.

Mitigating Kubernetes Security Vulnerability when using ExternalIP Services (CVE-2020-8554)

Earlier this month the Kubernetes project discovered a security issue affecting multitenant clusters: If a potential attacker can already create or edit services and pods, then they may be able to intercept traffic from other pods (or nodes) in the cluster. An attacker that is able to create a ClusterIP service and set the spec.externalIPs field can intercept traffic to that IP.

Application Modernization

Application modernization is an inevitable transition for enterprises with a futuristic business plan. It begets new capabilities and scalability with its new flexible environment. ZiniosEdge helps enterprises to modernize their infrastructure and legacy application with advanced cloud technologies. ZiniosEdge offers application modernization process guide, architecture assessment, design, and execution plan. Plus we will help to facilitate application cloud deployment using #Containers #Microservices #Kubernetes.

Introducing MinIO Support in Sematext

Sematext Logs is a Log Management-as-a-service. Think of it as your own central location for logs in the cloud. If you prefer or need to keep logs in your own environment instead of shipping it to the cloud Sematext Enterprise, designed to run on your own infrastructure, makes that possible. You can collect logs from any part of your software stack or infrastructure, IoT devices, network hardware, and much more.

Kubernetes GitOps with Rancher Continuous Delivery

As the number of Kubernetes clusters under management increases, application owners and cluster operators need a programmatic way to approach cluster management. Rancher CD solves this by creating a git driven engine for applying cluster changes. Declarative code is stored in a git repo. As changes are committed to the repo, linked clusters are automatically updated. Gitops keeps all your clusters consistent, version controlled, and reduces the administrative burden as you scale.
