Client Overview
The Municipal Corporation of Gurugram (MCG) is the governing body responsible for the urban infrastructure and administration of Gurugram, one of India’s fastest-growing financial and industrial hubs. As a key player in the “Digital India” initiative, MCG manages critical citizen services, including property tax, urban planning, and civic administration. The MCG E-Office (Tax Application) is the backbone of their revenue collection, serving millions of citizens and requiring 100% data integrity and high availability.
The Requirements
To support the city’s rapid digital growth, MCG required a complete overhaul of their aging infrastructure. The primary goal was to eliminate single points of failure and modernize their database environment. Key requirements included:
- Database Modernization: Upgrading from legacy Oracle 11g R1 to the more secure and efficient 12.1 Release.
- Platform Migration: Moving the entire operating environment from RedHat Linux to Oracle Linux on Oracle Virtual Machine (OVM).
- High Availability: Implementing an Active-Passive Cluster to ensure zero downtime.
- Disaster Recovery: Establishing a Standby Database at a remote DR location to protect against regional failures.
- Continuous Support: Reliable, 24/7 on-site operational maintenance to ensure system health.
Solution from IT Wings Infosystem
IT Wings delivered a comprehensive technical solution covering Database (DBA), Operating Systems (OS), and Infrastructure Management:
Seamless Migration & Upgrade
We executed a precise migration of the OS to Oracle Linux over OVM and successfully upgraded the Oracle database to version 12.1, ensuring data integrity throughout the transition.
Resilient Architecture
We deployed an Active-Passive Cluster on OVM. In the event of a primary server failure, the passive node takes over automatically with minimal failover time.
DR Synchronization
A dedicated standby database was configured at the DR site using Oracle Data Guard protocols, ensuring that MCG’s tax data is synchronized in real-time and recoverable in minutes.
Unified Hardware Management
We integrated and optimized the Application Servers, Database Servers, and Backup Servers to work as a unified, high-performance ecosystem.
Round-the-Clock Managed Services
To guarantee 99.9% uptime, IT Wings provides 24/7 on-site support, managing the DC-DR Annual Maintenance Contract (AMC) and all day-to-day operations.
The Business Outcomes
The implementation resulted in a high-performance, “always-on” environment for MCG’s tax services:
Zero Data Loss
The standby DR setup ensures that even in a total site failure, MCG’s critical tax data remains safe and recoverable.
Improved Performance
The upgrade to Oracle 12.1 and Oracle Linux on OVM led to faster query processing and smoother user experiences for the E-Office application.
Enhanced Reliability
The active-passive cluster significantly reduced unplanned downtime, ensuring citizens can access tax services without interruption.
Operational Peace of Mind
With 24/7 on-site support from IT Wings, the MCG IT team can focus on governance while we manage the underlying complex infrastructure.
Core Competencies Gained
Through the MCG E-Office project, the IT Wings team refined several mission-critical capabilities:
- Complex Migration Strategies: We perfected the "Double Migration" workflow—simultaneously upgrading the Database version while shifting the underlying Operating System and Virtualization layers.
- Business Continuity Planning: Our team gained deep insights into synchronizing high-volume tax data between DC and DR sites to ensure zero data lag.
- Government-Grade Security: We implemented rigorous security protocols required for e-governance applications, ensuring the tax data is encrypted and resilient against cyber threats.
- Preventative Maintenance: By providing 24/7 on-site support, we developed a proactive monitoring system that identifies and resolves hardware or software glitches before they impact the end-user.
Conclusion
The successful implementation of the DC-DR (Data Center & Disaster Recovery) infrastructure for the MCG E-Office marks a pivotal shift in Gurugram’s journey toward a truly digital and resilient governance model. By modernizing legacy databases and establishing a fail-safe active-passive environment, IT Wings Infosystem has ensured that the “heart” of the city’s tax and administrative services is always protected.
