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

As Vietnam's financial sector was rapidly digitizing, customer expectations for fast, secure, and near always-on banking were rising. In the past year, over half of new Techcombank customers joined through digital channels, and 91 percent of transactions were conducted digitally. Recognizing this shift, Techcombank accelerated its digital roadmap to stay ahead of demand.

To continue delivering at scale, the bank evaluated its on-premises infrastructure and identified constraints that could impact long-term agility. Its architecture—built on third-party solutions—required manual scaling and extended provisioning timelines. These operational complexities risked slowing innovation during periods of high growth.

With digital transactions surpassing 8.6 million on a single day, the bank took a strategic step to establish a more agile, scalable platform.

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.

With over 50 percent of compute workloads now running on AWS, Techcombank is accelerating its roadmap to become Vietnam’s first private bank to cross 1 trillion VND in assets. This modernization effort is also expected to generate projected cost savings of up to US$10.4 million over five years. The savings are driven by improved infrastructure efficiency, reduced downtime, and simplified operations.

Looking ahead, Techcombank is deepening its investment in artificial intelligence (AI), ecosystem expansion, and sustainable finance. The bank plans to embed AI-driven intelligence across its operations to enhance productivity and personalization. It is also broadening its digital ecosystem to include services across payments, investments, insurance, and wealth management.

"Modernizing on AWS has empowered us with the scale and agility to securely serve millions of customers, while fostering a collaborative environment where high-quality IT talent can thrive. Together with AWS, we are driving technological advancement and redefining banking experiences through data, digitalization, and people. As we approach the finish line of our five-year strategic plan in 2025, our aspiration is to be recognized as the most dependable, innovative, and trusted financial institution in Vietnam — one that truly changes banking and changes lives,” said Nguyen Anh Tuan, the chief information officer of Techcombank.
