Nowadays, the popularity of financial data has been increasing dramatically. Almost everyone is following stocks, currencies, and cryptocurrencies on a daily basis. Customers wish to access financial market data in a fast, reliable, and uninterrupted way to follow the pricing of stocks, make analysis within graphs, and more. For this reason, financial data vendors take a crucial role to transmit not only real time but also historical data to customers in a rapid and reliable way.
As a leading fintech company, one of our critical missions is to deliver historical market data to your customers no matter what! To accomplish this;
- ForInvest’s DevOps Engineers decided to set up a distributed, replicated, secure and self-managed mongoDB powered by AWS.
- ForInvest Software Engineering team developed high-quality, fast, and secure REST APIs.

I’ll mention architectural design and infrastructure set up to clarify how ForInvest delivers a serious amount of historical data to customers in milliseconds.
Architectural Design & Infrastructure Setup
When you deliver historical market data to your customers at scale, you need to consider a few things:
- High Availability
- Scalability
- Replication
- Rapid Delivery
- Secure Communication
The following diagram includes every aspect mentioned above.
High Availability
To provide HA, ForInvest DevOps team has deployed containerized mongoDB instances distributed along many availability zones in AWS.
Scalability
To maintain consistent service availability under high load, ForInvest DevOps team has implemented automated scaling in AWS.
Replication
To maintain the same data set along with distributed mongoDB instances, our engineering team configured mongoDB in replica set mode. Thanks to the replica set, data has always been synchronized for each of the mongoDB instances.
Rapid Delivery
MongoDB indexes structure is applied to our REST APIs to efficiently execute queries. Therefore, MongoDB uses a related index to limit the number of documents it must inspect.
Secure Communication
Last but not least – security! Our DevOps team configured a replica set with keyfile authentication. Enabling keyfile auth requires not only user authentication but also key-based internal authentication of replica set members.
Conclusion
It is very important to reach historical data in an uninterrupted, fast and reliable way from the customer’s perspective. Historical data enables the tracking of improvement over time which gives key insights. These insights are essential for driving a business. One of our primary focus is to transmit historical data to our customers by leveraging latest technology with our financial services.
