HashiCorp Packer is an open-source tool for creating identical machine images for multiple platforms from a single configuration source. Rather than manually configuring servers after deployment, Packer bakes your configuration — packages, users, services, certificates — directly into the image at build time, embodying the immutable infrastructure pattern. The resulting AMIs, OVA files, or container […]
How to Install and Configure Kubernetes (k3s) on Windows Server 2025 Running Kubernetes workloads that include Windows containers requires a hybrid cluster — Linux nodes handle the Kubernetes control plane and Linux workloads, while Windows worker nodes join the cluster to run Windows Server container pods. k3s, a lightweight Kubernetes distribution from Rancher, makes this […]
Jupyter Notebook is an interactive computing environment that allows you to create documents containing live Python code, equations, visualisations, and explanatory text in a single file. Notebooks (.ipynb files) are the standard format for data exploration, machine learning experiments, scientific computing, and educational tutorials because they let you execute code in small cells, inspect results […]
How to Set Up Work Folder Sync with AD Integration on Windows Server 2025 Work Folders is a Windows Server role service that gives users a consistent, policy-controlled location to store work files and synchronise them across domain-joined and non-domain-joined devices. Unlike consumer sync services, Work Folders operates entirely within your organisation’s infrastructure and integrates […]
Pacemaker is a high-availability cluster resource manager that, combined with the Corosync messaging layer, enables automatic failover of services between cluster nodes. When a node or service fails, Pacemaker detects the failure and restarts the affected resources on a surviving node, minimising downtime. This tutorial builds a two-node active/passive HA cluster on RHEL 9, configuring […]
How to Implement Zero Trust Architecture on Windows Server 2025 Zero Trust is a security philosophy built on a single, uncompromising premise: no user, device, or network location is implicitly trusted. In traditional perimeter-based security, once a user or device crossed the corporate firewall, they were trusted to access internal resources freely. Zero Trust inverts […]
How to Install NGINX on Windows Server 2025 While IIS is the native web server on Windows Server, NGINX has become a popular alternative and complement for Windows-based deployments — particularly as a high-performance reverse proxy, load balancer, or static file server sitting in front of an IIS or Node.js backend. NGINX for Windows is […]
How to Configure IPsec Transport Mode for Server-to-Server Encryption on Windows Server 2025 Protecting east-west traffic between servers on the same network is often overlooked, yet it is one of the most critical layers of a defence-in-depth strategy. IPsec Transport Mode encrypts only the payload of each IP packet while leaving the original IP header […]
How to Set Up VPN Site-to-Site with Windows RRAS on Windows Server 2025 A site-to-site VPN connects two physically separate networks — typically two branch offices or a headquarters and a data center — through an encrypted tunnel over the public internet, making both networks appear as a single unified network to devices on either […]
