- CIOs/CFOs cutting runaway cloud spend without losing governance
- IT Architects/Platform Teams standardizing control across hybrid/edge
- DevOps/SRE needing local latency + cloud-grade automation
- Retail/Manufacturing/Healthcare edge deploying at dozens/hundreds of sites
- Security/GRC teams wanting unified audit, RBAC, and policy across on-prem + cloud
- Azure = muscle (hardware) + brain (control plane). You can rent the brain while supplying your own muscle.
- Azure Arc “badges” non-Azure machines/clusters so Policy, Defender, Monitor, RBAC apply from the same portal.
- Azure Local brings core Azure services to those Arc-managed boxes: VMs, AKS, networking—on your desk.
- Small form-factor hardware (Intel i5/i7, Ryzen; 16–64 GB RAM; NVMe SSD) is enough for a mini region.
- Mail-and-plug edge rollout: ship pre-vouchered units, plug power/Ethernet, machine appears in Azure ready for policy.
- Benefits: near-zero latency, tiny power draw (~40–50 W), no colo, centralized lifecycle via Arc.
- Skip building a domain forest for two nodes. Use certificate-based identity with Azure Key Vault.
- Vault stores cluster certs/keys/BitLocker secrets; machines mutually auth with zero-trust simplicity; unified audit via Azure.
- Zero-touch provisioning: voucher USB → phone home → enroll → Arc claims nodes.
- Create a site, run validation, deploy Azure Local (compute/network/storage RP, AKS).
- Provision VMs or AKS via the same wizards you use in public Azure; enable GitOps for auto-updates at the edge.
- Arc registration: free; you pay mainly for optional governance/observability (Defender, Policy, Monitor).
- Replace 24Ă—7 VM rent with once-off hardware + electricity; keep Azure security/compliance intact.
- Hybrid sweet spot: stable workloads local; burst/global workloads stay in public regions.
- Mini-PC with VT-x/AMD-V, 32–64 GB RAM, NVMe SSD (OS) + NVMe SSD (data)
- Reliable Ethernet; optional secondary node for HA/live migration
- Enroll nodes with Azure Arc; attach to Resource Group/Subscription
- Choose Key Vault–backed local identity (no AD); enable RBAC + PIM
- Store secrets/certs in Key Vault; enable audit logging
- Voucher USB → zero-touch enrollment → assign to Site
- Run readiness checks (firmware, NICs, storage throughput)
- Deploy Azure Local (compute/network/storage RPs, AKS)
- Apply Azure Policy: tagging, region residency, baseline hardening
- Enable Defender for Cloud and Azure Monitor/Log Analytics
- Set up Update Management and Backup where needed
- Create VMs via Azure Portal; configure availability across nodes
- Deploy AKS; wire GitOps for continuous delivery at edge sites
- Standardize images (Packer) and IaC (Bicep/Terraform) for repeatability
- Track Monitor/Defender/Logs usage; tune retention and sampling
- Right-size hardware; plan 3-year refresh; keep a cold spare
- Run quarterly DR drills (voucher re-enroll, GitOps redeploy)
- Keep Azure’s brain, own the brawn. Arc + Local gives cloud-grade control without the per-hour meter.
- Mini-PCs are enough. Ship, plug, enroll—edge sites behave like mini regions.
- Ditch legacy AD at the edge. Key Vault–based certificates give lighter, auditable zero-trust.
- Same portal, policies, and audit. Hybrid without the governance gaps.
- Opex → Capex. Predictable spend, local performance, centralized security.
