How to install Kubernetes on Linux (AlmaLinux)
Kubernetes is an open-source framework for handling containerized workloads and services that allows declarative setup and automation. In today's dynamic IT landscape, Kubernetes has become a fundamental technology for organizations adopting containerization and microservices architectures. It provides a standardized and efficient way to manage and scale applications, ensuring high availability, fault tolerance, and resource optimization. With features like automatic load balancing, rolling updates, and self-healing, Kubernetes simplifies the complexities of deploying and managing modern applications, making it an integral part of the DevOps toolkit.
What is GitOps?
If you're a web developer, you've most likely heard about Git, GitHub, DevOps, and GitOps. While DevOps and GitOps are similar approaches to improving the software development process, GitOps is the more modern pathway used today. As companies grow and their software teams expand, they must control their software development while improving efficiency and workflow. But, getting down to brass tacks, what is GitOps really? Let's uncover all that is involved with it.
How to Install Jenkins on AlmaLinux
Jenkins is an open-source continuous integration server. It is a tool for continuously compiling and testing software projects. In the field of Continuous Integration (CI), the concepts from CI are combined with those from Continuous Delivery (CD) — also known as Continuous Deployment — in the CI/CD pipeline. See our The Best DevOps Tools for Infrastructure Automation for more information about this growth area in advanced software development techniques.
What is Kubernetes Used For?
As web applications become more complex and tasked with doing more, the demand puts stress on IT teams and their infrastructure. If you pair that with the expectation that development timelines should be shorter to accommodate quicker deployment strategies, then software companies are in a bind. Tech companies have a trump card they can use to make development easier, even under the increasing pressure of time constraints.
The Top 5 Free Containerization Tools
Introduction
In 2006, several Google engineers started to work on a Linux kernel feature called Cgroups (Control Groups) to limit and isolate hardware resource usage (e.g., RAM, CPU, disk I/O, network, etc.). Eventually, this functionality was merged with the Linux Mainline Kernel in 2008, and that paved the way for all containerization technologies that we use today, like Docker, Cloudfoundry, LXC, etc.
How Does Containerization Work?
Introduction
If you're invested in the world of web development, you might have already heard of containerization and all its advantages or even enjoyed them yourself by using one of the many available containerization solutions. It’s not an exaggeration to say that software containerization has changed the world, just as the change from bare metal to virtual machines (VMs) did.
How To Install and Configure an Istio Service Mesh
What is a Service Mesh?
A service mesh is a layer that aids the interaction between services or microservices. It helps control the flow of incidental information between services using a logic built into the service mesh. The mesh itself utilizes what’s called a sidecar proxy to share that data over the network.
What is Desktop-as-a-Service?
Introduction
As firms advance towards a more modern infrastructure, the Desktop-as-a-Service (DaaS) model is becoming an increasingly popular cloud-based system. Desktop-as-a-Service is a multi-tenant, cloud computing solution in which a service provider furnishes a virtual desktop to an end-user over the internet. A provider typically manages the infrastructure, including the security updates, available desktop applications, data storage, and backups. In specific instances, DaaS users manage these services individually. According to Gartner via Workspot:
How to Store Secrets in Kubernetes
What is a Secret?
A Kubernetes Secret is an object that enables us to store and manage sensitive information. A Secret can contain data like SSH keys, OAuth data, or other user authentication information like passwords. It is typically stored within a cluster in a manner native to Kubernetes. Using a Secret object provides more granular control over how highly sensitive data is used. It also lowers the risk of data exposure to unauthorized parties.
How to Install and Configure KubeKey
What is KubeKey?
KubeKey is the newest Kubernetes installer for KubeSphere. KubeSphere is a distributed OS management system for cloud-native applications using Kubernetes as its kernel. It provides a plug-and-play structure for seamless integration of many third-party applications. It is somewhat similar in nature to MiniKube for installing Kubernetes.
