Infrastructure Briefing — April 22, 2025

AWS published its 2025–2027 infrastructure roadmap, detailing new availability zones, sovereign regions, and continuity guardrails hyperscalers must absorb into enterprise resiliency planning.

Executive briefing: Amazon Web Services released its 2025 Global Infrastructure Roadmap, locking construction schedules for twelve new availability zones across North America, Europe, the Middle East, and Asia-Pacific while expanding dedicated sovereign regions in Germany and Japan. The roadmap details multi-AZ failure scenarios, control-plane partitioning, and emergency power enhancements customers must incorporate into continuity architectures this year.

Key infrastructure signals

  • New availability zones. AWS confirmed Phoenix, Madrid, Kuala Lumpur, and Tel Aviv zones opening by Q4 2025 with 100% renewable energy matching.
  • Sovereign regions. Germany and Japan sovereign regions add independent control planes with local-only support staff, targeting regulated sectors requiring data residency.
  • Power resilience upgrades. AWS committed to 96-hour on-site fuel reserves and dual grid feeds in every new facility, summarising diesel reduction targets and microgrid pilots.

Control alignment

  • Multi-region design patterns. Update AWS Well-Architected resilience blueprints to leverage the new AZ pairings and sovereign endpoints.
  • Regulatory mapping. Document how German and Japanese sovereign regions support BaFin, Bundesbank, and FSA data residency requirements for financial services customers.
  • Sustainability reporting. Align enterprise ESG disclosures with AWS’s renewable energy and diesel reduction metrics to evidence infrastructure sustainability.

Detection and response priorities

  • Enhance observability baselines for the new AZ pairs, ensuring control plane telemetry detects partition events covered in AWS’s failure scenarios.
  • Map incident runbooks to AWS’s updated regional outage drills, including cross-region failover timelines and sovereign support escalation paths.

Enablement moves

  • Prepare board updates translating AWS’s roadmap into enterprise migration sequencing, compliance benefits, and cost commitments through 2027.
  • Run resilience game days validating that workloads tagged for sovereign control planes meet latency, residency, and operational guardrails.
