Cloudvisor made our migration from Heroku to AWS incredibly smooth. They built a scalable and cost-efficient AWS infrastructure that perfectly meets our needs. The fact that the entire project was covered by AWS funding was a huge bonus. Now, we have a future-proof setup ready for growth!
Challenges
HelloSafe was previously running its services on Heroku, which presented several limitations
- Scalability constraints – Growing usage led to slow response times and difficulties in handling traffic spikes efficiently.
- High operational costs – Increasing expenses for resources and add-ons, with limited opportunities for cost control.
- Limited flexibility – Lack of customization options and control over infrastructure, hindering optimization.
- Need for a robust setup – Required a scalable, automated, and secure solution to support future growth.
Solutions
Cloudvisor designed and executed a fully AWS-funded migration, ensuring zero cost for HelloSafe’s transition from Heroku to AWS. The architecture prioritized scalability, security, and cost efficiency. The migration was carried out in four structured phases:
Phase 1: AWS Account Setup & Initial Deployment
- AWS accounts were pre-configured following security best practices, including provisioning key security services and Terraform for infrastructure as code.
- Symfony & NextJS applications were deployed in a staging environment.
Phase 2: CI/CD Pipeline & Verification
- A CI/CD pipeline framework was implemented to automate deployments and streamline updates.
- The client verified application functionality in the staging environment.
Phase 3: Production Deployment & DNS Update
- Symfony & NextJS services were deployed in the production environment.
- Traffic was redirected to the new AWS infrastructure, ensuring a seamless transition.
Phase 4: Project Handover & Knowledge Transfer
- Cloudvisor provided architecture documentation and best practices guidelines.
- A final knowledge transfer session ensured the HelloSafe team could confidently manage their AWS setup.
