16. How it was implemented
UAT
32 GB Total Memory
12 vCPUs / 6 VMs
340 GB Storage
10Mbps VPN/ME circuit
2 days delivery
Production
64 GB Total Memory
26 vCPUs / 13 VMs
1250 GB Storage
10Mbps VPN/ME circuit
1 day delivery

17. Experience gained
IT internal resistance to Cloud can be easily reverted
Versatile Cloud control panel is a key part of the solution provided
Security is of a major concern and the Cloud customer must in detail
go through all his concerns with the Public Cloud Provider
Agility and total SLA initially, will drive big IT organizations to the
Public Cloud
Cost, Security, Agility and Total SLA will drive the smaller IT
organizations to the Public Cloud

18. Way forward
UAT & Development environment
Slowly all UAT and Development related servers and storage
infrastructure are moving to Public Cloud
Disaster Recovery (DR) implementation
The existing DR architecture and new Business Continuity resources
will be moved to Public Cloud
Legacy infrastructure
Applications that we plan to substitute in the next six months (6m) to
one year (1yr) window are candidates for Public Cloud
The above migration path can be financially feasible due to the fact
that the relative Telco resources can be a part of the Total Public Cloud
offering
