Expert articles on managed services, cloud architecture, and datacenter operations — written by engineers who do this work every day.
HCI has displaced traditional three-tier (server + SAN + network) architecture for most new on-premises deployments. VMware vSAN and Nutanix AOS lead the market but differ significantly in architecture, resiliency model, and operational overhead.
Read article →Single-ISP connectivity is a single point of failure for any business-critical environment. BGP multi-homing with two upstream providers gives you ISP-level redundancy and the ability to control inbound and outbound traffic paths.
Read article →Ceph provides unified block, object, and file storage on commodity hardware — making it the leading open-source storage platform for colocation and private cloud deployments. This article covers the architecture, CRUSH map design, and practical sizing for production clusters.
