Configuring storage for Kubernetes Persistent Volumes (PVs) involves several steps: 1. Understand Persistent Volumes (PV) and Persistent Volume Claims (PVC) Persistent Volume (PV): A cluster resource that represents physical storage. Persistent Volume Claim (PVC): A request for storage by a pod. It allows pods to use the PV. 2. Choose a Storage Backend Kubernetes supports […]
Migrating applications from one Kubernetes cluster to another can be a complex process that requires careful planning and execution to avoid downtime and data loss. Here’s a step-by-step guide to help you manage the migration effectively: 1. Assess the Source and Target Cluster Source Cluster: Evaluate the current state of the source cluster. Note Kubernetes […]
Start by identifying the repetitive tasks eating your time: provisioning, monitoring, patch management, backups, scaling, security updates. Be specific about what you want to achieve — less downtime, faster deploys, compliance, cost savings — so you can measure whether automation actually helps. Configuration management These tools enforce desired state across your fleet. Pick one and […]
Configuring IT infrastructure for secure mobile application development requires a combination of best practices, security measures, and efficient resource management. Here’s a step-by-step approach tailored to your role and expertise: 1. Define Requirements and Assess Risks Identify the programming languages, frameworks (e.g., Flutter, React Native), and tools your developers use. Assess security risks: unauthorized access, […]
Implementing a Software-Defined Data Center (SDDC) means transitioning traditional infrastructure into a fully virtualized, automated, and policy-driven environment. Here’s a step-by-step approach: 1. Understand SDDC Concepts and Objectives Before starting, make sure you and your team grasp the core layers: – Compute Virtualization: Virtual machines, containers, and Kubernetes. – Storage Virtualization: Software-defined storage (e.g., vSAN, […]
Upgrading a Kubernetes cluster takes careful planning to avoid downtime and workload disruptions. Here are the steps: 1. Pre-Upgrade Planning a. Review Release Notes Check the Kubernetes Release Notes for the version you plan to upgrade to. Understand deprecations, breaking changes, and new features. Verify compatibility with add-ons, plugins, and third-party tools (e.g., CNI, CSI, […]
