SUSE Manager - The Linux Manager (a quick look)

“Manage any Linux, anywhere” is the current theme of SUSE Manager. This is the one stop solution to manage a complete Linux estate. Yes, SUSE Manager is a complete lifecycle manager for any Linux distribution. It doesn’t matter which Linux distro is that, it could be Red Hat Enterprise Linux or CentOS or Ubuntu or Oracle Enterprise Linux etc, all could be easily managed using SUSE Manager, whether it is on-premise or on edge or in cloud.  

Uyuni (a fork of Spacewalk, based on SaltStack) is the upstream for SUSE Manager 4 and later releases. "Spacewalk" was used earlier. 

OpenStack Is On The Raise - Part1

Well, someone said OpenStack is fading out and its presence in the industry is shrinking day by day. Agree, that was a long time ago and we need to rephrase that statement saying ‘most of the organizations are using or wish to use OpenStack’ now.  The industrial trends and analysis points to OpenStack adoption in Hybrid Cloud space as one of the major cloud software’s. As enterprises try to be more secure and comply with the country wide norms & regulations the inclination towards OpenStack or alternative technology has become aggressive. So, in this blog page I’m trying to punch in the points and driving factors for enterprises in adopting OpenStack cloud solutions on broader perspective.  

SUSE in Container Orchestration

Yes, SUSE being one of the top Linux open source software distributors has made a tremendous contribution in the Container Orchestration space with open source Kubernetes on the bottom layer. The story of SUSE's Container Orchestration journey kicked off after its acquisition of Rancher Labs (in the year 2020*) which was one the leading Container Orchestration distributions in the world. As of now, SUSE Rancher is one of the widely used Container Orchestration platforms around the world, The Red Hat OpenShift, VMware  Tanzu, Hasicorp Nomad, Docker Swarm, Apache Mesos etc, are some of the other leading Container Orchestration platforms available in market. Lets not forget the Container Orchestration options available from the hyperscalers such as Microsoft's AKS (Azure Kubernetes Service), Google's GKE (Google Kubernetes Engine), AWS Elastic Kubernetes Service (EKS) etc,. which are considered as Managed Container Orchestration Tools. 

AI And Automation In Cybersecurity And Threat Detection

Artificial Intelligence and automation are rapidly transforming the cybersecurity landscape, bringing new tools and techniques to the forefront of threat detection. These technologies are helping organizations to quickly identify and respond to security threats, reducing the risk of data breaches, and improving the overall security posture. In this article, we will explore the role of AI and automation in cybersecurity and threat detection, and how these technologies are helping organizations stay ahead of the curve in the fight against cybercrime.

Deploy Single Node K8s Cluster Using K3s In 2 Minutes

Yes, deploying a single node Kubernetes cluster using K3s is easy, fast and hassle free. On top of all these K3s is meant for light weight K8s workloads hence it doesn't need much system resources. Anyone who wishes to learn K8s and practice using kubectl could get the K3s deployed on a VM running with 4 GB and practice. The deployment process of K3s is so simple, it is hardly a matter of running 3/4 commands. The Kubernetes single node cluster would be ready to practice in 2 minutes.

K3s is a Lightweight Certified Kubernetes Distribution from SUSE which is open source. Similarly, there is RKE (Rancher Kubernetes Engine) and RKE2 which are also different flavors by SUSE under the open source umbrella. However, SUSE Rancher is the SUSE's flagship and commercial version which supports management of different K8s clusters which can be onboarded from cloud, on-premises or even deploying new K8s setup on bare metal, cloud, or on-premises environments. We can truly call it as K8s Orchestration. 

Random Linux Troubleshooting Flow-Charts

As we all know Technical Flow Charts are very helpful in troubleshooting. Especially, for anyone who is new or learner these types of flow-charts are ideal to guide them. This logical approach would certainly help anyone to understand and fix issues at the correct layer. Without this logical approach it would be difficult to point to the exact layer of issue otherwise, a non-logical approach may not give good results or would be time consuming. In this blog post, I’ve documented a few such logical flow-charts which help a Linux Infra Admin/Staff in troubleshooting and fixing issues. I’d keep adding such flow charts in future as well. So, keep watching this blog page to get latest updates on this.
