System Architecture : Payment Wallet
Microservice based architectural design for Payment wallet
Disclaimer: We are starting new series under System Architecture banner, where the focus will be on learning different kinds of distributed systems architecture ranging from microservices, monolithic to event driven etc. through real systems examples. Focus of these articles will be limited on understanding the architecture, data and control flow of these various systems archs, feel free to give suggestions/inputs in the comments.
Focused architecture: Microservices-based architecture
A microservices-based architecture is well-suited for designing a payment wallet like Google Pay due to its modularity, scalability, and flexibility.
For a payment wallet system, microservices architecture allows for seamless handling of high transaction volumes, integration with third-party systems, and continuous deployment of updates. Lets deep dive into payment wallet architecture.
Key Features of a Payment Wallet
A payment wallet like Google Pay typically supports:
- User Onboarding: User registration, KYC verification, and account setup.
- Balance Management: Wallet funding, balance checks, and refunds.
- Transactions: Peer-to-peer (P2P)…
