What this means
We run our own ops and security stack end-to-end. No “best effort”, no black boxes. The result is predictable capacity, fast recovery, and tight control of blast radius.
Core pillars
- Always-on: 24×7 on-call with clear SLOs and runbooks.
- Fast MTTR: cold/hot spares on-site, validated swap procedures.
- Isolation-first: management plane on a separate, locked-down network.
Operations
24×7 on-call
Rotating primary/secondary, live dashboards, paging policies tuned to severity. Post-incident reviews drive concrete fixes.
Spare-parts pool
Critical SKUs stocked on-site (PSU, fans, NICs, SSDs, GPUs). Swap time measured, rehearsed, documented.
Change management
Maintenance windows, staged rollout, canaries, rollback-by-default. Infra as Code for reproducible state.
Backups & recovery
Scheduled snapshots, encrypted at rest; periodic restore drills validate RTO/RPO assumptions.
Security
Isolated management network
Air-gapped from tenant traffic. Admin access gated behind MFA, short-lived credentials, and bastion policies.
Segmentation & least privilege
Per-tenant isolation, scoped service accounts, audited privilege elevation.
Defense-in-depth
WAF, DDoS protection, egress controls, image signing, and runtime checks. Supply-chain pinning for critical components.
Monitoring & audit
Metrics, logs, and traces with retention; tamper-evident audit trails; alerting on anomaly and policy violations.
Service posture
- Designed for uptime: capacity headroom plus spares beats wishful thinking.
- Small blast radius: failure domains are contained by design.
- No guesswork: documented runbooks, tested procedures, measured outcomes.
FAQ
Do you rely on third parties for ops?
We operate in-house. Vendors exist, but control, paging, and recovery remain our job.
How do you handle hardware failures?
Detect, isolate, swap. Spares are stocked; swaps are rehearsed; tenants are migrated with minimal disruption.
Is the management network exposed?
No. It’s segregated from tenant traffic and gated behind MFA and short-lived credentials.
