Introduction to Hyper-V Checkpoints on Windows Server 2019 Hyper-V Checkpoints (formerly called Snapshots) capture the state of a running virtual machine at a specific point in time, allowing you to revert the VM to that state if needed. This is invaluable before applying updates, making configuration changes, testing software installations, or performing any risky operation. […]
Introduction to Hyper-V Storage Migration on Windows Server 2019 Hyper-V Storage Migration moves a virtual machine’s storage — its VHD/VHDX files, configuration file, snapshot files, and smart paging file — from one storage location to another while the VM continues running. Unlike Live Migration (which moves a VM between hosts), Storage Migration moves only the […]
Introduction to Hyper-V Live Migration on Windows Server 2019 Live Migration moves a running virtual machine from one Hyper-V host to another with zero downtime — the VM continues running throughout the move, and users experience no interruption. This is essential for host maintenance (patching, hardware replacement), workload balancing across a cluster, and responding to […]
Introduction to Hyper-V Replication on Windows Server 2019 Hyper-V Replica is an asynchronous virtual machine replication feature built into Windows Server 2019 that continuously replicates VMs from a primary Hyper-V server to one or more replica servers. It provides a disaster recovery capability without requiring shared storage — each site has its own independent storage. […]
Introduction to Hyper-V Virtual Networking on Windows Server 2019 Hyper-V virtual networking is the fabric that connects virtual machines to each other, to the physical network, and to the Hyper-V host. Windows Server 2019 introduces several significant networking improvements over previous versions, including support for Software Defined Networking (SDN), the Virtual Filtering Platform (VFP) extension, […]
Introduction to IIS Centralized Certificate Store on Windows Server 2019 The IIS Centralized Certificate Store (CCS) allows you to store SSL/TLS certificates on a central UNC file share and have all IIS servers in a web farm read certificates directly from that share. Without CCS, you must manually install and renew certificates on every individual […]
Introduction to IIS Web Farm on Windows Server 2019 An IIS Web Farm is a group of two or more IIS servers that together serve the same web application, providing horizontal scalability and high availability. As traffic increases beyond what a single server can handle, a web farm distributes load across multiple servers. When a […]
Introduction to IIS HTTP/2 on Windows Server 2019 HTTP/2 is the second major version of the HTTP protocol, standardised in RFC 7540. It introduces multiplexing (multiple concurrent requests over a single TCP connection), header compression (HPACK), server push, and binary framing — all of which significantly reduce latency and page load times compared to HTTP/1.1, […]
Introduction to IIS WebSockets on Windows Server 2019 WebSockets provide a full-duplex, persistent communication channel over a single TCP connection between a client and server. Unlike standard HTTP request/response, WebSockets allow the server to push data to clients without the client polling. This is used in real-time applications including chat systems, collaborative tools, live dashboards, […]
Introduction to IIS Reverse Proxy on Windows Server 2019 A reverse proxy sits in front of backend servers and forwards incoming client requests to those servers, returning the responses to clients as if the proxy itself generated them. On Windows Server 2019, IIS combined with the Application Request Routing (ARR) module and URL Rewrite provides […]
