Finanbest is a company in the fintech sector that offers its clients a Fully automated way of investing in mutual fund portfolios and pension plans. All of this through a 100% digital process (including electronic signature).
In recent years, fintechs have changed the foundations of competition in financial services and leading analysts predict that they have come to completely change the global financial landscape.
Finanbest had started its project on a “classic” hosting platform that was beginning to show potential performance improvements, since at certain times offered response times below their quality standards and those expected by a very demanding digital client.
The existing architecture was analyzed, which was based more on VPS servers than on high-performance systems, with a mix of production and development environments that offered options for evolution and improvement.
From apser a platform was proposed with clear division between development and production environments. Also, each platform would be made up of separate servers (frontend+backend) for decouple the presentation and business layers.
In the development environment, EC2 instances of the T family were used, which are turned off outside of working hours, while in the production environment, M type instances with greater resources were deployed.
Additionally, the client's domains were migrated to Amazon Route53 to integrate it with Amazon Cloud Front, with the aim of improving application loading times, and with Amazon Web Application Firewall (WAF,) for web frontend protection.
Finally, the backup and compliance policies were reviewed given that it operates in an environment regulated by financial institutions, reaching the definition of a New backup and restoration policy for the platform in the event of contingencies.
The main objective of the project was to reduce loading times and to organize the service through automated measurements of performance, usage and capacity. This was achieved immediately thanks to the increased server performance and to CloudFront deployment.
As Finanbest's customer base has grown, it has been able to scale the solution according to its needs with a minimal impact on your operations.

Currently under study is the MongoDB database separation, which is now on the backend EC2 servers, to migrate it to a DocumentDB service.
Additionally, a usage analysis of the current platform has been carried out in which the following have been detected: Overprovisioned resources that can be reduced to optimize costs.
