Data Center Architecture & Operations — detailed
1. Core components & physical layers
Servers: blade, rack and modular systems (virtualised with VMware/Hyper-V/KVM). Standardised images, immutable infrastructure pipelines and asset tagging for lifecycle management.
Storage systems: SAN (Fibre Channel), NAS (SMB/NFS) and object storage with tiering (SSD/HDD/cold) and replication across zones.
Networking: Core/distribution/access layers, redundant uplinks, BGP with provider diversity, edge firewalls and micro-segmentation for tenant separation.
2. Power, cooling & facilities
Power: N+1 UPS, redundant PDUs and automatic generator failover with scheduled load-transfer tests and fuel management procedures.
Cooling: CRAC units, hot/cold aisle containment, chilled water systems and environmental monitoring (temperature, humidity) with alert thresholds and automated remediation playbooks.
Tier strategy: Design platforms to meet Tier III/IV availability depending on SLA — active-active clusters, distributed storage, and synchronous/asynchronous replication.
RTO/RPO planning: Defined by workload — cold backups for archives, warm replicas for databases, and near-zero RPO for critical transactional systems.
Failover tests: Quarterly DR drills, runbooks for manual and automated failover, and post-mortem lessons captured in the CMDB.
4. Backup, retention & recovery
Policy-driven backups with immutable retention, offsite replication, periodic restore drills and verification checksums.
Point-in-time recovery for databases, application-consistent snapshots and tested restore runbooks with SLA-driven RTO targets.
Versioning and lifecycle rules to manage storage costs while keeping compliance retention windows (eg. GDPR, industry rules).
5. Monitoring, automation & tooling
Monitoring stack: Metrics (Prometheus), logs (ELK/Opensearch), traces (Jaeger), synthetic checks and alerting with escalation policies.
DCIM & inventory: Real-time capacity views, PUE monitoring, asset lifecycle, and automated ticketing integrations.
Automation: IaC (Terraform), configuration management (Ansible/Chef), CI/CD pipelines for infra changes, and change windows with automated canary rollouts.
6. Security, compliance & audits
Network segmentation, host hardening baselines, vulnerability scanning, and timely patching tracked through a centralized vulnerability management system.
Compliance frameworks: ISO/IEC 27001, GDPR readiness, PCI-DSS for contact-centre payment flows and auditable logs for inspections.
Incident response: dedicated IR playbooks, forensic capture procedures and reporting timelines aligned with regulatory requirements.
7. Operations & runbooks
Comprehensive runbooks for common tasks (patching, backups, restores, failover) and step-by-step incident escalation matrices.
