Challenges of the FinTech Industry

Being a FinTech industry owner, you might be concerned about some aspects that matter to the FinTech application user. Security, traffic, and analytics are the prime concerns; let us check them in depth.

1. Security

Security is a significant challenge for FinTech startups. FinTech applications deal with sensitive financial data, which makes them attractive targets for cybercriminals. FinTech startups must ensure that their applications are highly secure and follow best practices for cybersecurity. This includes implementing strong authentication and encryption measures, monitoring potential security threats, and planning to respond to security incidents. Failing to secure a FinTech application properly can result in a loss of trust from customers, reputational damage, and financial losses.

2. High Traffic

High traffic is another common issue faced by FinTech applications. FinTech apps need to handle a large volume of user traffic & hence business owners need to ensure that their applications can support many users without slowing down or crashing. FinTech applications typically require a high degree of availability and performance, as users expect to be able to access their financial data and conduct transactions in real-time.

3. Analytics

FinTech startups need strong analytical capabilities because data is at the heart of the FinTech industry. Analyzing data can provide valuable insights into customer behavior, transaction patterns, and market trends that can inform business strategy and drive growth.

One key area where analytics is crucial for FinTech startups is risk management. FinTech applications deal with sensitive financial data and must be able to detect and prevent fraudulent activities. Strong analytical capabilities can help FinTech startups identify fraudulent behavior patterns and take proactive steps to prevent fraudulent transactions. Analytics can also help FinTech startups to assess credit risk and make data-driven decisions about lending.

How Ruby on Rails for FinTech can Eradicate the Challenges?

Ruby on Rails has what it takes to build a reliable, robust, and efficient Finance application. It will rightly overcome the core issues that FinTech startups face. Here is how Ruby on Rails for FinTech app development is a heavenly match.

1. RoR for FinTech resolves Security Issues

RoR is designed with security in mind and includes many built-in features that make it easier for developers to create secure applications. RoR has several security features, including cross-site scripting (XSS) protection, SQL injection protection, and protection against CSRF (Cross-Site Request Forgery) attacks. These features make it harder for attackers to exploit common vulnerabilities.

2. RoR Scalability overcomes the Traffic Surge Challenges

The RoR framework can help FinTech startups to overcome traffic surge issues by providing scalability in several ways:

Traffic Surge Challenges

Horizontal scaling:
RoR allows FinTech startups to scale horizontally by adding more servers or instances to handle increased traffic. RoR is designed to work well with cloud-based infrastructure, which can help FinTech startups quickly and easily add more instances as needed to handle traffic surges.

RoR includes built-in caching mechanisms that can help FinTech startups improve their applications’ performance by reducing the number of requests that need to be made to the database. By caching frequently accessed data, RoR can help reduce the database load and improve application performance during traffic surges.

Asynchronous Processing:
RoR supports asynchronous processing, which can help to improve application performance and handle traffic surges by allowing requests to be processed in the background. This can help to free up resources and reduce the load on the application server during traffic surges.

Load Balancing:
RoR works well with load-balancing solutions that can help FinTech startups to distribute traffic across multiple servers or instances. Load balancing can help improve application performance and ensure the application remains available during traffic surges.

Overall, RoR’s scalability features can help FinTech startups to overcome traffic surge issues by providing horizontal scaling, caching, asynchronous processing, and load balancing. By leveraging these features, FinTech startups can ensure their applications remain available and performant, even during traffic surges.

3. RoR Data-analysis Integration to overcome Analytics Challenges

Ruby on Rails (RoR) can integrate with data analysis tools to help FinTech startups overcome the analytics challenge in several ways:

Analytics Challenges

Data Visualization:
RoR can integrate with data visualization tools like D3.js, Chart.js, and Highcharts to provide interactive and informative data visualizations. Data visualization can help FinTech startups to understand their data better and identify trends and insights that may not be apparent in raw data.

Data Warehousing:
RoR can integrate with data warehousing solutions such as Amazon Redshift and Google BigQuery to store and manage large volumes of data. Using data warehousing helps FinTech startups to consolidate data from multiple sources and perform complex queries and analyses.

Machine Learning:
RoR can integrate with machine learning tools such as TensorFlow and Scikit-learn to perform predictive analysis and make data-driven decisions. Machine learning can help FinTech startups to identify patterns in data and predict future behavior, such as identifying high-risk customers or predicting market trends.
