A fintech company dealing in digital wallets approached Mindbowser to get a well-tailored user interface and stable product that can serve without hiccups as the product grows to million users.
We performed a high-level analysis on the company’s existing application platform and understood the performance requirements.
In this blog, we share how Mindbowser helped the customer build a highly scalable and secure platform architecture (Micro-service based Architecture).

Conceptualization of the system architecture
We put together a plan for the different pieces of the backend and frontend along with scaling, security, monitoring and many other aspects of the system.
- The challenges were around handling all roundups and exchange related transactions to avoid any errors and make sure to develop a robust architecture around it
- We considered separate microservices for each exchange integration so that it is loosely coupled with the main application and works independently. Adding and removing new exchanges to be made simpler
- Log Monitoring and performance monitoring of different parts done through open-source systems like Elastic Search, Logstash and Kibana and similar.
- We considered some caching mechanisms to speed up the performance of APIs and the frontend.
- Introduced API gateway to add extra security and API monitoring. This benefited the company to block or limit API request rates and comprehended third-parties that will be integrated in the future.
- For autoscaling, we applied to dockerize the microservices with either K8s or ECS.
- For security apart from the private VPC network, we used KMS for encryption at rest at the database and EBS level; also, IAM roles will be used to access databases and other resources to avoid any security breaches

Bonus#1: To keep costs in check, we created a tentative budget for one environment and planned to use 3 or 4 environments depending on the needs. We extrapolated the numbers keeping in mind that the budget for other environments would keep reducing
Bonus #2: For execution, a CI/CD pipeline was put for different environments to work in cohesion along with an automated deployment strategy and steps. We automated code review before any build goes into planned environments i.e., stage/dev/QA/prod.
Conclusion
With this summary, we share with you many things about microservices-based architecture. Our solutions have helped healthcare, fintech and insurtech companies scale up without a hitch while relying on the underlying architecture.
