Enterprise Hybrid Cloud Infrastructure
Enterprise Hybrid Cloud Infrastructure
Three pieces of an enterprise estate that had to work across public cloud, on-premise virtualization, and a private cloud at once — active-active database clustering without native shared storage, one object-storage API for every environment, and a mail platform that recovers in minutes instead of hours.
Case studies
01 / Data & storageOracle RAC on AWSA 21+ node Oracle RAC cluster running active-active database failover on AWS, built around software-defined clustered storage to work around AWS's lack of native shared-SAN block storage. →
02 / Data & storageHybrid object storageA self-hosted distributed object storage layer unifying backups, ERP media, and mail archives across a public cloud, an on-prem data center, and a private OpenStack cloud behind one S3 API. →
03 / Resilience & DRMail disaster recoveryAn automated EC2 failover system for a single-instance enterprise mail platform, cutting recovery time from 4+ hours of manual recovery to under 3 minutes, paired with tiered S3 backups and DNS-authenticated delivery. →
