CBN had its E-Library Server hosted on Vmware Infrastructure with Internet Solutions. CBN does not have access to the host, only the virtual machine, its users connect over the web to access E-Library.
Lack of visibility into host of the virtual machines and the cost of the maintenance cost was high, security was a concern, backup and DR were part of the experienced issues that triggered migration to Azure.
The objective was to migrate E-Library server from Internet Solutions cloud services, for consolidation of its workloads on Azure, make its Line of business applications highly-available, enjoy the compute and storage scale , as well as business and disaster recovery
Assessment of the servers were done pre-migration, Azure Migrate was leveraged for the migration, but the disk/vm files were exported first, VMDKK was converted to VHD, the VHD was tested and hosted on Hyper-V, and Azure Migrate was used to shift it to the cloud. This long route was due to inaccessibility to the VMware host. The Landing zone was created (Resource groups, Virtual Network, Virtual Network Gateway for IPsec VPN, NSG) extension of connectivity to on-premises via IPsec VPN and Point-to- site. Test-Failover was done to validate data synchronization and functionality, after which Failover was configured. Redirection of users to Azure VM was configured and on-premise server was shutdown. Both teams (Reliance and CBN) worked together to deliver on the project within time slice and handover training was conducted.
The Server is Accessible from anywhere, connectivity of remote users and web users to the Line of business application. Protecting from all forms of attack. Remote desktop can be accessed over private IP addresses due to the VPN created. RBAC was configured for adequate access.
