Challenges
A leading telecommunications and network services provider in Australia faced major challenges in preparing its IT environment for cloud migration. The company operated a large, complex estate of 450 servers with over 615,000 unique network connections.
The complexity of the network environment was one of the most significant obstacles. Traditional, legacy migration assessment tools had been unable to provide clear visibility into dependencies across applications and services. At the same time, the presence of outdated operating system versions added risk, making modernization planning more difficult.
Solution
CloudHound was deployed to deliver a modern, MAP-ready assessment of the provider's IT estate.
- Using its advanced network analysis, CloudHound automatically mapped application and service dependencies across the environment.
- This capability isolated discrete application groupings, making it clear which workloads could migrate together safely.
- CloudHound's discovery also identified legacy operating systems, creating a clear path to upgrade or retire outdated platforms as part of the migration.
- The platform modeled modern cost optimization strategies, including Compute Savings Plans and RDS Reserved Instances,, to balance performance, cost, and long-term sustainability in AWS.
Results
- 403 servers and 615,000 network connections fully analyzed in days, not months.
- Application groupings isolated for simplified and low-risk migration planning.
- Legacy operating systems identified, providing a structured path to modernization and risk reduction.
- Cost savings of $881K/year identified, a 52% reduction in TCO.
- Optimized migration pathways created for AWS, enabling faster, lower-cost modernization with reduced risk.
Conclusion
After struggling with legacy migration assessment tools, the provider turned to CloudHound and achieved transformative results. CloudHound's advanced network analysis untangled the complexity of their environment, uncovered significant cost savings, and highlighted modernization opportunities by flagging outdated operating systems. The result was a clear, low-risk roadmap for migration and modernization.
