Client Overview
Marsh McLennan is a global leader in professional services, providing risk management, strategy consulting, and HR consulting solutions. With a massive technology infrastructure supporting their worldwide operations, they manage over 12,000 applications across hundreds of servers, requiring sophisticated DevOps automation to maintain operational excellence and rapid deployment capabilities.
Global professional services leader with worldwide operations
Managing 12,000+ applications across multiple server environments
Complex infrastructure spanning AWS cloud and on-premise systems
Heavy reliance on GitHub for version control and collaboration
Need for automated deployment processes to reduce manual errors
Requirement for centralized monitoring and management platform
Key Challenges
Marsh McLennan faced significant challenges managing deployments across their massive infrastructure of 12,000+ applications. Manual deployment processes were error-prone, time-consuming, and created bottlenecks that slowed down development teams. The lack of standardized CI/CD pipelines resulted in inconsistent deployments and frequent production issues.
With hundreds of servers across AWS and on-premise environments, monitoring and managing deployments became increasingly complex. The absence of automated GitHub PR-based deployments meant developers spent excessive time on manual processes instead of focusing on feature development, while DevOps teams struggled to maintain oversight across the entire infrastructure.
Manual deployment processes across 12,000+ applications
Lack of standardized CI/CD pipelines and automation
Complex multi-environment server management challenges
Limited visibility into deployment status and failures
The Solution
We developed a comprehensive internal DevOps automation platform that centralizes deployment management, streamlines CI/CD pipelines, and provides real-time monitoring across all 12,000+ applications. Built using Node.js and modern technologies, the platform automates GitHub PR-based deployments and provides centralized control over AWS and on-premise server infrastructure.
The platform features automated deployment triggers from GitHub pull requests, real-time application monitoring, server health dashboards, and comprehensive logging systems. DevOps teams now have complete visibility into deployment status, while developers can focus on code development with automated deployment processes handling the infrastructure management.
Automated GitHub PR-based deployment workflows
Centralized management dashboard for 12,000+ applications
Real-time server monitoring and health checks
Node.js-based microservices architecture
AWS and on-premise infrastructure integration
Automated CI/CD pipeline orchestration
Comprehensive logging and error tracking systems
Role-based access control and security management
Our Development Approach
We implemented a scalability-first, automation-focused approach that prioritizes enterprise-level infrastructure management while ensuring seamless integration with existing GitHub workflows and AWS services. Our methodology emphasized reliability and developer experience optimization.
