With the client having different business verticals including offshore, onshore, construction services, modular fabrication and engineering services, client’s vision was to move towards Hybrid Datacenter which is scalable and available with enterprise level security.. Microsoft on-boarded IFI Techsolutions to help LTHC to achieve this vision by adopting Azure Cloud Solutions
LTHC needed to stable and secured connectivity with redundancy to avoid business downtime. Seamless and secured access to Primavera users who are connecting from external network Every industry faces challenges with legacy application, LTHC has no exceptions, came across similar challenge, where one of there COTS application required to do Rehost which was on windows server. As re implementation was not possible due to efforts hours from multiple team involved and business was not willing to provide downtime.
Landing zone deployed with Express route from TCS and Airtel to maintain ISP level redundancy, used as active – active to utilize all available bandwidth. LTHC identified 20 VMs out of which 2 VMs was considered as Lift and Shift, This was 2 tier application with Front end and Backend with Propriety code from Vendor based on Dotnet framework. Primavera application was moved as re implementation , as it was latency sensitive for external users AVD solution was proposed and deployed which worked seamlessly. AVD solution was suggested to avoid disruption due to bandwidth fluctuation for users who are login from external network
IFI Suggested to do lift and shift via Azure migrate tool, which helps to replicate VM on block level to Azure, and during off business hours ,final cutover performed. This helps to reduce efforts of re installing applications and its component along with integrations.
Azure File Share deployed with Private Endpoint to access and AD integration to maintain on premises AD authentication and to be accessed local secure network via EXPRESSROUTE.
This shift of application from on-preimise to Azure will enable L&T Hydrocarbon to be more agile and flexible. Configuration of Azure Backup will help LTHC to scale their business with high-end security along with greater speed, reliability and scalability as compared to on-premise applications by reducing the cost.
