Servers, storage, virtualization, backup, and the systems that run the business
IT infrastructure is the discipline that keeps the business running when the cloud bill comes due, when ransomware hits, when the datacenter loses power, and when the database server you forgot about turns out to be running payroll. The SoftwareMarketplace.Net IT infrastructure hub publishes the operational guides, reference architectures, and decision frameworks that infrastructure engineers, system administrators, and IT operations teams actually use in production environments.
Our coverage spans the full infrastructure stack. Virtualization: VMware vSphere, Proxmox VE, Hyper-V, KVM, and the hybrid patterns that connect on-premises virtualization to public cloud. Linux administration: hardening, automation with Ansible and SaltStack, performance tuning, and the troubleshooting patterns that distinguish senior administrators from junior ones. Storage: SAN, NAS, object storage, software-defined storage, the trade-offs between block, file, and object, and the backup and disaster recovery strategies that actually work when the building floods. Networking integration, identity infrastructure, monitoring, capacity planning, and the documentation practices that survive staff turnover.
We write for system administrators, infrastructure engineers, IT operations leads, and the technology directors responsible for the platforms that run the rest of the business. Our coverage is vendor-aware but not vendor-driven. When we compare VMware to Proxmox, or a SAN to an object store, we explain the operational, licensing, and skill-set implications of each choice. Our certification content covers the Red Hat, VMware, Microsoft Windows Server, and Linux Foundation tracks written by people who hold those credentials and have implemented the underlying technologies.
Start with the pillar architecture guides if you are designing a new infrastructure stack or planning a virtualization migration. Use the latest articles to keep up with vendor releases — particularly Broadcom-era VMware licensing and Microsoft Windows Server changes — that materially affect your operating environment. The troubleshooting and operational guides walk through the diagnostic patterns experienced administrators use.
A practical, current hardening checklist for production Linux servers — identity, kernel, network, logging, and the controls that actually reduce risk.
Backups that nobody has restored are not backups. Here is the operational playbook for a 3-2-1-1-0 strategy that survives ransomware, hardware loss, and human error.
Block, file, and object storage solve different problems. Here is how to match each to the workloads that actually need it.
