You have been hired to assist with a migration to an ITaaS environment. The company has offices
in Atlanta, Dubai, and London, with 5000, 2000, and 3000 employees, respectively. A data center exists in each location, and most services have been virtualized. Messaging services are provided locally to the user.
You have just performed an assessment of the environment. The results are shown in the exhibit.
The CIO is interested in closing one of the data centers and migrating some or all of the services to a public cloud service provider (CSP). Any services that do not get migrated to the CSP will be hosted at one of the other two data centers. Network latency averages 8 milliseconds between the Atlanta and London offices, and 10 milliseconds between the London and Dubai offices. Traffic between Atlanta and Dubai is routed through London.
The eCommerce application is external facing and is hosted at all three data centers. Atlanta services 50% of the users in North and South America. London services 40% of the users in Europe and Asia. Dubai services 10% of the users in Africa and Australia.

-RPO: 4 hours -RTO: 1 hour -Availability: 99.995%
Your recommendation is to close the Dubai data center over a one-year time horizon.
