Data Center Strategy and Migration With VMware

Together with VMware and AWS as partners, we transformed the digital landscape and trajectory of our Global 2000s financial services client.


Our financial services client was constrained by poorly aligned investments in IT infrastructure after years of government conservatorship.

The symptoms of those conditions began to manifest over time. Responses for enhanced product and service delivery were inadequate, failing to address quickly changing business and marketplace conditions. Additionally the client’s DR/BCP was insufficient for meeting business and regulatory requirements.


Following a strategic review of the company’s data center ecosystem, the IT leadership team proposed a business case that would transform its entire infrastructure by vacating both their out-of-region recovery site and primary on-premise in-region data center – moving the majority of application workloads to a hybrid cloud end state.

With the need to move to a hybrid cloud end state, the majority of virtualized workloads were to be relocated to in-region and out-of-region AWS data centers running VMware’s hosted VMC solution. These were directly connected with paired colocation sites. The DMZ and remaining physically hosted workloads were to be migrated to the colocation sites.

Services and Solutions

Having a trusted relationship with the client’s leadership, we were engaged to develop the migration strategy for all applications and services. This included profiling and sequencing production applications in clusters to minimize potential performance degradation.

We provided overall management for the program’s orchestration and implementation, inclusive of Steering Committee materials. Our management included all migration related activities to VMC and physical colocation moves.

Working with our client’s team, we prepared a program level calendar view of all 600+ applications and services, including move dates and target sites (VMC vs. Colocations). The program level view then drilled down to map the individual VMs and physical devices associated with each application’s move dates for approximately 2,500 production instances and 6,500 non-production instances. This enabled prepopulating change tickets months in advance of move dates.

At the conclusion of the project, all applications were successfully migrated to their target end states. The migration strategy and approach developed by CST enabled the client to effectively balance both schedule and BAU operational risks resulting from the migration success.
