Overview
A leading Finnish telecom multinational is migrating 200+ enterprise apps from on-premises to Google Cloud with a cloud-first approach to optimize TCO and accelerate SDLC. The initiative drives IaaS and PaaS adoption to reduce long-term cloud costs. A DevOps pipeline streamlines provisioning, migration and auto-scaling. Additionally, leveraging open-source OS and databases lowers enterprise licensing expenses.
The Challenge
The client faced several challenges in migrating 200+ enterprise applications to Google Cloud with a cloud-first approach
- End-of-Support (EOS) and End-of-Life (EOL) IT infrastructure causing escalating CapEx costs
- Need for a partner experienced in large-scale cloud migrations with competitive pricing
- Standardizing the migration process and enhancing productivity using advanced tools
- Lack of a strong program for driving business agility and speed-to-market
The Objective
The objective was to migrate over 200 enterprise applications in a phased approach while optimizing cloud infrastructure
- Migrate applications in three waves over 18+ months
- Utilize a customized DevOps pipeline for efficient cloud service provisioning
- Optimize change request efforts and timelines for cloud infra and app maintenance
- Ensure faster time-to-market and improved application performance
The Solution
We implemented a strategic, multi-phase approach with a strong focus on accelerating migration and adoption of cloud technologies
- Leveraged PRIZM for effective app assessment and target disposition
- Enabled code upgrade accelerators and DevOps pipeline to provision IaaS and PaaS services
- Increased adoption of Google Cloud IaaS and PaaS to reduce long-term consumption costs
- Migrated VMs to GKE/Serverless environments for scalability and cost optimization
The Impact
The migration delivered significant benefits in terms of cost savings, performance and operational efficiency
- Achieved 30%+ TCO savings through IaaS and PaaS adoption
- Reduced time-to-market by 25%, ensuring faster delivery of applications
- Improved user experience and app uptime by up to 50%, driving better client satisfaction
- Streamlined cloud infrastructure and operations, reducing long-term cloud consumption costs
