Techcombank Modernizes Digital Banking Platform on AWS, Achieves 30% Quarter-over-Quarter Growth

Techcombank’s sustained and collaborative journey with AWS, which spanned strategic planning, co-innovation, and shared commitment, led to the successful migration of its digital banking systems. Over an implementation period of just six months, both parties invested deeply in solution design, change management, and infrastructure readiness. This milestone reflects Techcombank’s long-term vision to transform digitally by partnering with a global leader in cloud innovation.

After the migration, Techcombank became the first bank in Vietnam to successfully modernize its Retail and Corporate Digital Banking systems on the cloud, thus marking a significant step in its broader five-year transformation roadmap. This scalable, cloud-native foundation has accelerated product development cycles, simplified infrastructure management, and facilitated the delivery of near real-time banking services with greater consistency and speed.

To support growing transaction volumes, the bank implemented Amazon Aurora MySQL, a fully managed relational database service built for scale and availability. By migrating to this service, Techcombank maintained consistent performance during peak periods and improved customer response times by up to 35 percent in the first week of migration.

The bank introduced Amazon ElastiCache, an in-memory datastore, to enhance the speed of routine operations such as balances checks and transaction history lookups. This helped reduce data access latency. Techcombank also used Amazon Managed Streaming for Apache Kafka (Amazon MSK), a service for processing near real-time data streams. With this, the bank streamlined backend communications and now delivered timely notifications across its digital channels.

The bank deployed Amazon Elastic Kubernetes Service (Amazon EKS) to orchestrate containerized workloads and improve deployment agility. As a result, development teams rolled out new features faster and with greater consistency across digital channels. This reduced time-to-market by 30 percent, improving the customer experience.

To strengthen platform reliability and operational availability, the bank integrated Amazon OpenSearch Service, a fully managed service for near real-time log analytics. Techcombank could now detect and resolve issues faster, contributing to a 10 percent reduction in downtime compared to the previous year for seamless and reliable banking experiences for its customers.

As part of its digital compliance initiatives, Techcombank also became the first bank in Vietnam to launch a cloud-based biometric electronic Know Your Customer (eKYC) system. The bank deployed the solution on its AWS-powered architecture to deliver security, scalability, and near real-time responsiveness, in alignment with new national regulations.

To migrate its data to the cloud, Techcombank used AWS Data Migration Service (AWS DMS), a managed service for migrating databases to AWS quickly and securely. Techcombank transferred 2 petabytes of data ingested from 5 billion records per day across 1,000+ customer data attributes, including sensitive financial data, using AWS DMS. It completed the migration without service interruption, preserving transaction integrity and maintaining continuity for customers.

Following the successful migration, the bank established a Platform Foundation team and collaborated with AWS technical experts to scale and sustain its cloud-first approach. Together, they built infrastructure-as-code pipelines to automate deployment workflows. Product teams could now operate independently and release new features without bottlenecks or operational delays.
