Cloud‑Native Architecture and Quantifiable Benefits at MyBank Using Ant Group’s SOFAStack

Recently, Ant Group and Forrester released a report showing that Ant Financial Technology helped financial institutions save over 100 million yuan in three years, with MyBank highlighted as a practitioner of cloud‑native technology.

Cloud‑native, driven by Kubernetes and container technologies such as Docker, represents a fundamental shift in application delivery for rapidly changing businesses.

MyBank’s chief architect, Yu Feng, explains that cloud computing enables massive, heterogeneous, dynamic data processing, faster machine‑learning‑driven analytics, and more efficient inter‑enterprise collaboration, while also improving development efficiency, reducing costs, and increasing stability.

As the first cloud‑based bank, MyBank relies on Ant’s self‑developed financial‑grade distributed architecture SOFAStack and the OceanBase database, delivering services to over 20 million small‑business customers.

MyBank’s three‑region, five‑center private‑cloud deployment provides scalable, high‑availability computing, elastic resource allocation, and global traffic control, enhancing business continuity.

To meet low‑cost, high‑availability, and regulatory requirements, MyBank adopted SOFAStack as the platform for its core banking system. SOFAStack offers a full‑stack solution for service construction, deployment, governance, monitoring, and disaster recovery, compatible with Dubbo and Spring Cloud.

The architecture separates core services (customer information, account management, payment, etc.) from business logic, boosting development efficiency and enabling rapid recomposition of banking value chains.

By adopting a multi‑active, geographically distributed architecture, MyBank achieves on‑demand scaling, seamless failover, and supports the transition from traditional IOE to distributed cloud computing.

Quantifiable benefits include:

New engineers’ onboarding time reduced from three months to two weeks.

Feature development cycles cut from one month to one week; application development from three months to three weeks.

Ops‑to‑dev ratio improved from 1:10 to 1:100.

Service Level Agreement (SLA) increased from 99.9 % to 99.99 %.

Additional qualitative gains are:

Rapid scaling for peak events such as Double‑11, expanding capacity fivefold in minutes.

Significantly improved disaster‑recovery capabilities, allowing automatic self‑healing.

Reduced cost for business innovation, enabling fast rollout of new services for rural finance and supply‑chain finance.

Looking forward, MyBank continues to open its technology stack, leveraging AI, facial‑recognition security, intelligent risk control, and the “310” model (3 minutes application, 1 second disbursement, zero manual intervention) to provide inclusive financial services.

Ant Group also collaborates with Southeast Asian financial institutions, offering virtual‑bank licenses and sharing technology to lower financing costs for SMEs, while the “Fanxing Plan” aims to partner with 1 000 institutions to serve 30 million small enterprises.
