An Insight into Digital Banking Architecture
Digitalization has transformed every area of our lives. Digital banking has also become a very common concept and everyone is highly familiar with its functioning. There are many aspects of digital banking architecture that are not known to a lot of people.
Types of Architecture
Digital banking architecture is mainly of four types. Let’s learn about them.
Monolithic Architecture - This architecture is built as a single, unified system that handles all the digital banking functions such as user authentication, transaction processing, and data storage. It is a traditional architecture and is still used by some banks.
Service-Oriented Architecture (SOA) - SOA is a modular architecture that breaks down the digital banking system into smaller, independent components called services. Each service performs a specific function, such as user authentication or transaction processing, and communicates with other services through standard protocols.
Microservices Architecture - Microservices architecture is similar to SOA but takes modularity to a more granular level. Each micro service is a small and self-contained element that has a specific function and communicates with other microservices through APIs.
Cloud-Based Architecture - Cloud-based architecture is becoming increasingly popular in digital banking. It leverages cloud computing services such as Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). The digital banking system is deployed on the cloud, and the bank pays for its computing resources. Cloud-based architecture is flexible, scalable, and cost-effective.

Features to Include in Your Digital Banking Architecture
While you are building your digital banking architecture, you need to add some features to it. Following are some popular digital banking features that you can add to your architecture. Let’s learn more about them.
User Authentication
User authentication is the process of verifying the identity of a user or entity who is trying to access a system or resource. It is a critical aspect of information security that aims to prevent unauthorized access, data breaches, and other malicious activities that can compromise the confidentiality, integrity, and availability of sensitive information.
Having a strong user authentication system is essential for businesses that collect and process customer data, such as financial institutions, healthcare providers, e-commerce websites, and social media platforms. Without proper authentication measures, attackers can easily impersonate legitimate users, steal sensitive information, or conduct fraudulent transactions, leading to reputational damage, financial loss, and legal liabilities. Two-factor authentication (2FA) is one of the most common methods of user authentication that involves the use of two different factors to verify the user's identity. This can include something the user knows (such as a password or PIN) and something the user possesses (such as a security token or mobile device).
Secure Data Storage
Secure data storage is a critical aspect of any digital banking system, as it ensures the protection of sensitive customer data. Robust security measures are necessary to safeguard this information from unauthorized access, theft, and other potential security threats.
Encryption is one of the most essential security measures used to protect customer data in digital banking systems. This technique involves converting data into a code that can only be deciphered with a specific key. This means that even if a hacker gains access to the data, they will not be able to read or use it without the encryption key. Additionally, firewalls are used to prevent unauthorized access to the system and to protect against various types of cyber attacks. Ensuring secure data stored in a digital banking system requires a combination of robust security measures, regular audits, and proactive measures to identify and address potential vulnerabilities.
