The customer is among the leaders in the telecommunications industry operating in its business niche. To deliver superb services the company utilizes data center infrastructure with complex hardware and software solutions.
The client faced the necessity to migrate its on-premise IT infrastructure running on an outdated VMware ESXi cluster (dedicated physical boxes) due to the shutdown of a classic data center in its current physical location.
The environment comprised a wide range of different services that needed to be migrated: AD DS, DFS, DHCP, File Servers, old custom 2-tier applications, BizTalk application cluster, IIS, TFS server, SQL Servers, etc
The client experienced the need to migrate as much of on-premises IT infrastructure resources which are being running on an outdated VMware ESXi cluster (dedicated physical boxes) as possible due to shutdown of a classic data center in the current physical location. The environment included a plethora of different services to migrate: AD DS, DFS, DHCP, File Servers, old custom 2-tier applications, BizTalk application cluster, IIS, TFS server, SQL Servers, etc.
The team proposed to use the built-in AWS capabilities and tools.
The choice was made in favor of the AWS server migration service. Most of the services were migrated using the lift-and-shift strategy. Once the VM images were uploaded to the cloud, Terraform was used to create the needed resources and perform the initial configuration. Minor architectural changes were made to DFS and DHCP. SQL Servers were migrated to AWS RDS PaaS offering.
HashiCorp Terraform, AWS RDS, AWS EC2, AWS CloudTrail, AWS Migration Service, AWS Database Migration Service.
All services are smoothly running in the cloud. As a result of the project implementation, the client has got better performance with lower specs due to smaller network latency and better rightsizing.
The switch to RDS allowed releasing the burden of OPS tasks. From a security perspective, all the migrated services were aligned with the cloud environment, leveraging storage encryption and strong network security. Thanks to all these benefits, the customer improved downtime KPI, enhanced business agility, and significantly decreased capital expenditure.
The client’s request was to partly migrate on-premise infrastructure to the cloud. As per the customer’s requirements, the application services should have been hosted in the cloud for cost reduction and efficient scaling. The database cluster should have been replicated in the cloud to cut costs of disaster recovery infrastructure and reduce downtime, but the write nodes should have remained in the local data center.
