The problem
Classic three-tier data centers struggle with east-west traffic, workload mobility and automation. Moving to a fabric is the right step, but a migration done without a clear tenant, policy and interconnect design recreates the old problems on new hardware.
Our approach
We design the underlay, overlay and policy model together, decide early how the fabric connects to the WAN, firewalls and cloud, and plan the migration in waves with tested rollback for every wave.
Typical deliverables
- Fabric design (EVPN/VXLAN, Cisco ACI)
- Data center interconnect and multi-site design
- Hybrid and cloud connectivity
- Migration plan with waves and rollback
