Phased Azure cloud migration case study

A SaaS company needed more room to scale than its local data center could provide. Transcendent planned a staged Azure migration that kept legacy systems operating while applications and data moved incrementally.

Client case study

Room to grow while keeping existing systems running

A SaaS company needed to move beyond its local data center. The migration connected Azure to the existing environment so applications could move in stages while legacy systems continued operating.

Local data center

Legacy systems and shared warehouse

VPN connection
Microsoft Azure

Cloud applications and dedicated databases

Cloud applications continued supplying the existing warehouse during the transition.

Client engagement 01

Moving a growing SaaS platform to Azure without a big-bang cutover

Situation

A SaaS company expected significant business growth, but its applications were hosted in a local data center. The estate included Windows Services, a website and blog, and a very large shared database that constrained scaling.

Business constraint

The company needed cloud capacity without taking every legacy system offline at once, and the new operating model still had to make financial sense.

Transcendent's role

Transcendent Software assessed the application estate, designed the hybrid transition, converted workloads, separated databases, and migrated the system one application at a time.

Approach

  1. Establish secure connectivity between the data center and Azure

  2. Convert Windows Services to Azure WebJobs and move the website to App Service

  3. Create dedicated Azure SQL databases while continuing to supply the legacy warehouse

  4. Move dependent systems incrementally, then use reserved Azure instances to control cost

Outcome

The system moved to Azure through staged transitions, and reserved cloud capacity helped reduce ongoing hosting costs.

What this engagement demonstrates

Cloud modernization can improve scalability and lower hosting cost while preserving operational continuity through an intentionally hybrid migration period.
