Migrating a SaaS Platform to DigitalOcean with Docker and Object Storage
Challenge
The company was running its entire SaaS platform on a single bare-metal server. This architecture limited scalability, complicated maintenance, and created availability risks in case of hardware failure.
The goal was to modernize the infrastructure and move to a more flexible cloud environment—without disrupting service to customers.
Solution
Nubosas designed and executed the migration to DigitalOcean, which included:
- Creating virtual machines (Droplets) tailored to the platform’s services.
- Containerizing core services with Docker for isolation and portability.
- Replacing local storage with DigitalOcean Spaces (Object Storage) for secure, scalable file management.
- Refactoring network and security configuration to ensure reliable access.
- A carefully planned migration with minimal downtime for end users.
In 2023, as a natural evolution, the Docker-deployed services were orchestrated with Nomad, keeping the stack on DigitalOcean while improving operational robustness.
Results
- A more flexible, scalable infrastructure with services split across multiple VMs.
- Reduced risk of outages thanks to separation of critical components.
- Easier deployments and day-to-day operations with Docker (and later Nomad).
- Optimized costs via a cloud model with adjustable resources.
- A SaaS platform ready for sustainable growth.
