Challenges faced by MSEDCL in migrating their IT infrastructure and managing their data center:

1. Legacy Application Migration:

• Moving old applications from physical servers to AWS cloud without business interruption.
• Ensuring smooth transition and compatibility of applications in the new environment

2. Data Center Integration and Disaster Recovery:

• Difficulties in integrating data centers and establishing disaster recovery capabilities at multiple locations.
• Ensuring seamless data replication, backup, and recovery across different sites.

3. Hardware Scalability:

• Challenges in scaling the hardware infrastructure to accommodate growing workloads and application demands.
• Ensuring sufficient computing resources to handle increasing data processing requirements.

4. Outdated HP Unix Configuration:

• Using an outdated HP Unix configuration due to the high expenses associated with upgrading.
• Limitations in performance, support, and compatibility with modern technologies.

5. Patch Management:

• Managing a large inventory of assets and facing challenges in patching and updating systems.
• Ensuring timely application of security patches to address vulnerabilities and maintain system stability.

6. Uptime and Hardware Flexibility:

• Migrating to a cloud environment to achieve a 99.99% uptime and gain flexibility in selecting preferred hardware.
• Emphasizing the ability to leverage pay-and-use services for better resource allocation.

7. Latency and Downtime:

• Facing significant problems with latency and downtime due to unsupported/out-of-warranty HP-UX systems.
• Misconfigured network settings affecting system performance and availability.

8. Unstable and Overutilized Hardware:

• Multiple Oracle, MS SQL server, SAP Sybase ASE, SAP ECC, and SAP Hana database servers running on unstable and overutilized hardware.
• Performance bottlenecks, system crashes, and resource constraints affecting data processing capabilities.

9. Data Encryption and Backup:

• Data encryption not set up correctly, potentially exposing sensitive information to security risks.
• Unreliable and unstreamlined on-premises backup and restore plan compromising data availability and reliability.

10, Access Control and User Management:

• Inadequate access control mechanisms, user management practices, and security management processes.
• Possibility of unauthorized access, data breaches, and compromised system integrity.

Outcomes achieved through the deployment of Orient's solutions for MSEDCL:

‍

1. Reduced Lock-in and Environment Maintenance:

• Utilized EC2 with SAP Workloads to eliminate lock-in and remove the need for engaging AWS features.
• Lift and shift technique facilitated the migration of apps and databases to the cloud without modification.

2. Efficient App Migration:

• Implemented the Rehosting mechanism to migrate on-premises apps to the cloud without altering them.
• Replicated complete virtual machines, including operating systems, apps, and databases, to a staging area in the target AWS Region using CloudEndure tools for disaster recovery.

3. Improved Query Performance:

• Query execution time reduced by 15-20% compared to the previous phase, demonstrating improved efficiency.

4. Enhanced Backup and Recovery:

• Transitioned from tape library backup to Veritas, instance images, and RDS snapshots stored in AWS S3.
• Demonstrated AMI restoration using backed-up EC2 instances for efficient recovery.

5. Cost Optimization:

• Reduced licensing costs primarily through AWS RDS services compared to previous expenses.
• Eliminated unnecessary hardware costs in the on-premises system and utilized savings to build additional AWS services.

6. Database Performance and Patching:

• Achieved significant improvements in database performance and patching jobs with the assistance of AWS RDS Services.

7. Secure Configuration:

• Configured all systems behind the firewall, ensuring that no configurations are visible to the public.

8. Disaster Recovery:

• Assigned point-in-recovery to SAP systems operating on AWS DC through AWS CloudEndure DR.

9. Oracle License Cost Reduction:

• Reduced Oracle DB core usage from 128 crores to 98 crores, resulting in a 30% decrease in Oracle licensing costs.
• Migrated all licensees from Unix-based systems to X86 architecture.

10. Efficient Backup Data Access:

• Moved backup media from tape library to AWS S3, enabling access to around 700 TB of data within 24 hours compared to a week-long process using tape
