Deliverables

What You Get

01

Migration Assessment

A complete inventory and risk profile of every workload. Dependency maps, licence checks, and a clear migration-wave plan before we write a single line of Terraform.

02

Target Architecture

Provider-agnostic reference architecture with cost modelling, resilience design, and compliance mapping. Built for your workload — not copied from a template.

03

Migration Runbooks

Step-by-step execution guides for every workload, including rollback procedures. Nothing is left undocumented or to chance during the cutover window.

04

Zero-Downtime Cutover

Live traffic migration using DNS-based or database-replication techniques. Your users never know the move happened. Neither do your on-call engineers.

05

Post-Migration Optimisation

30-day stabilisation period with daily monitoring, performance tuning, and right-sizing reviews. We do not hand over and disappear.

06

Knowledge Transfer

Complete architecture documentation, runbooks, and structured handover sessions so your team owns the environment fully from day one.

Case Study

Zero-Downtime Migration of a 12M-User Payments Platform

A Mumbai-based payments processor needed to move from a single-cloud AWS estate to a multi-cloud AWS+GCP active-active architecture to meet new RBI regulations, without any downtime for their 12 million active users. CloudBrx delivered the migration in eight weeks, with cutovers rehearsed four times before go-live.

FAQ

Common Questions

We use live-traffic migration techniques including DNS-based switching, database replication, and shadow environments. Every cutover is rehearsed multiple times in a staging environment with realistic load before the production window.

Everything from a 5-server startup to a 400-instance enterprise estate across 14 AWS regions. The methodology scales — the planning rigour does not change with size.

A small application stack: 2–4 weeks. A complex enterprise estate: 8–16 weeks. We always deliver a detailed timeline at the end of the discovery phase before any commitment.

Every cutover has a documented rollback procedure that has been tested in rehearsal. We have never had to use a full rollback in production — but we are always ready to.
