DevOps Roadmap 2026: From Beginner to Expert.

DevOps is no longer just a buzzword it’s the backbone of modern software delivery. As we move into 2026, companies expect DevOps engineers to do far more than manage CI/CD pipelines. Cloud optimization, security, automation, and platform engineering are now part of the role. If you’re confused by endless tool lists and unrealistic expectations, this […]

KubeVela: An Application-Centric Platform for Kubernetes Delivery

Introduction In modern cloud-native environments, organizations are increasingly adopting Kubernetes to deploy and manage applications. While Kubernetes provides powerful primitives such as Pods, Services, and Deployments, it also introduces significant complexity. Developers are often required to understand low-level infrastructure concepts, YAML configurations, and operational details that are outside their core responsibility. KubeVela was created to […]

Dynamic Storage in Kubernetes using OpenEBS with StatefulSets

Introduction: Persistent storage is a crucial requirement for stateful applications running on Kubernetes. OpenEBS provides a cloud-native solution for dynamic storage provisioning, enabling pods to retain data even when they are restarted or rescheduled. By leveraging OpenEBS, Kubernetes users can create custom StorageClasses and dynamically allocate Persistent Volumes (PVs) using Persistent Volume Claims (PVCs). This […]

Kubernetes Resource Management: Pods, Resource Requests, Limits, and ResourceQuota

Deploying a StatefulSet with Manual Persistent Volume (hostPath) in Kubernetes-(Tutorial-II)

Introduction In Kubernetes, StatefulSets are used to run stateful applications that require stable storage, ordered deployment, and persistent identities.In this guide, we manually create a PersistentVolume (PV) using hostPath, then deploy a StatefulSet that uses this PV for data persistence. In Kubernetes, some applications need to store data permanently and keep their names stable even […]
