Strategic Migration from AWS/Azure to Dedicated Servers

Optimising the IT Portfolio in the Context of Cost Predictability
Can dedicated servers replace the flexibility of the cloud in a mature SaaS environment?

Migration from the cloud

Problem

The project focuses on a mature SaaS platform designed to optimise operating costs. In the current cloud model, disproportionately high fees for managed services, coupled with predictable traffic, have become a significant financial burden. The ‘infinite scalability’ offered by cloud providers has proved unnecessary, leading to inefficient resource management and a decline in product margins.

Solution

Zastosowano audyt usług w celu zidentyfikowania zasobów o stałym, wysokim zapotrzebowaniu. Zamiast korzystania z wirtualnych maszyn z wysoką marżą, wdrożono strategię oparcia infrastruktury na serwerach dedykowanych w Hetzner Online, co zapewnia surową moc obliczeniową w konkurencyjnej cenie.

Key elements of implementation

Full migration of resources:

Migrating the technology stack and database server to physical machines ensures cost optimisation and performance.

Bare Metal Automation (IaC):

Terraform and Ansible have been implemented for server management, enabling agile and automated deployment processes.

Network optimisation:

Setting up an isolated internal network ensures secure communication between instances and eliminates data transfer costs.

Why are dedicated servers a strategic solution?

  1. Stability and Predictability: With a consistent traffic profile, dedicated servers offer predictable costs and eliminate unpredictable data transfer charges.
  2. Uncompromising performance: Dedicated infrastructure delivers the full power of physical resources, ensuring application stability and performance.

Business value

Migrating to dedicated servers allows you to regain control over your budget, whilst offering a modern DevOps approach without compromising on performance.

Results

  • An 80% reduction in infrastructure costs per month.
  • Improved application performance thanks to dedicated CPU and RAM resources.
  • Full automation of physical infrastructure management using Infrastructure as Code (IaC).
