How incumbent banks can accelerate digitalization with BankLiteX on AWS
Global banking in the digital age
Global banking is being disrupted from many angles. The COVID-19 pandemic has produced a profound change in consumer habits, fuelling the growth of digital banking. For many banks, the legacy technology that once drove business success now inhibits progress due to a lack of flexibility and scalability.
Banks are also are facing challenges around loyalty and a disjointed experience across channels. Other external factors are contributing to these challenges, including the widespread adoption of mobile services, new digital native market entrants, consumer demands for personalization, and critical industry requirements around compliance and regulations.
In the meantime, digital challengers are forging ahead, with the ability to innovate and scale as necessary. Incumbent banks have responded to the new market dynamics in three different ways, with varying degrees of success:
- Build a new digital core. This “rip and replace” option is risky, expensive, and increasingly viewed as old fashioned.
- Build on a greenfield site. Many banks have built digital banks from scratch with the intention of migrating the entire operation in due course. While this does have several advantages including agility of deployment, in the long term it is likely legacy platforms will need re-factoring investments.
- A progressive modernization. This option is quickly gaining popularity as a practical solution. It allows banks to harness the flexibility of modern technologies, including cloud, to pursue a progressive modernization, driven by specific business needs. It also mitigates risk and aligns costs with business success.
In this blog post we describe how GFT supports the third approach using BankLiteX, a modular, end-to-end solution that enables firms to create and deploy a cloud-based digital banking entity. BankLiteX, which runs on AWS, was developed by GFT in collaboration with Thought Machine, an AWS Technology Partner that accelerates the digital transformation of banking platforms by providing a market-ready cloud native deployment of its next gen core banking platform, Vault.
With BankLiteX, GFT has harnessed the power of AWS technologies and Thought Machine’s Vault to build a world-class banking platform for the digital age. BankLiteX offers a framework built on well-architected best practices validated by AWS to deliver functionality through modular ‘blocks’ that accelerate development, testing, and deployment by 40%.
Challenges of digitalization
Digitalization is a major challenge that touches every part of the bank, from core processing to the customer experience. A truly digital bank must be data-driven and offer a digital end-to-end experience. Digital bank transformation is a major undertaking but doing nothing is not a viable option. There are many drivers of bank transformation, none of which can be considered in isolation:
High cost of change. Ongoing maintenance and the high costs and risks of implementing changes on mainframes becomes unsustainable. About two thirds of a bank’s IT budget is consumed running the bank, and time to market for new products is often too long.
Competitive pressure. Newer competitors are unencumbered by legacy technology and benefit from a lower cost structure, modern technology architectures, and greater agility. These challengers directly disrupt traditional business models by offering rapid account setup, no fees, no fines, and financial planning tools at no additional cost. These banks combine a digital-first approach to banking and state-of-the-art business processing.
Customer expectations. Online retailers and e-commerce providers have increased customer expectations and put the customer at the heart of everything. As a result, customers in all industries expect an engaging, personalised experience that is omnichannel, dynamic, and helpful. With these high expectations, customers are intolerant of cumbersome, outdated apps.
Multichannel management. Managing a multichannel approach requires the harmonization of both management technology (databases, analytics, Customer Data Platform (CDP), Customer Relation Management (CRM) platforms, and others) and operational technology (campaigns, messaging, decision management, orchestration). Banks need to mine data from these systems to segment the market and create targeted campaigns with personalized content to be delivered to the customer’s preferred channel.
Changing local regulations. A wave of regulations, such as PSD2 (open banking regulation) and CECL (current expected credit loss) dictate that banking should become more open, competitive, and better prepared to manage risk. In reality, open banking is bringing financial services into line with other industries by harnessing the power of open application program interfaces (APIs) to boost innovation and facilitate collaboration. Traditional mainframes are not suited to the rapidly changing local regulations of this era. To succeed in this environment, technology must also be open.
BankLiteX is GFT’s response to these new market dynamics. Designed to appeal equally to start-ups and incumbent banks wishing to modernize, it offers a roadmap to digital banking success based on proven methods and modern technologies.
What is BankLiteX?
BankLiteX empowers you to deploy a cloud-based digital bank quickly and at minimal risk. BankLiteX is a fully modular system designed around Vault. In practice, it offers a simple and effective solution to many of the challenges explained in the previous section.
Designed as a building-block architecture with pluggable components, BankLiteX is hosted entirely on AWS infrastructure. This enables any bank to create modern, highly flexible end-to-end solutions by delivering capabilities to support a multiple-entity, multi-brand, and multi-currency strategy. The following diagrams show a sample high-level architecture of a digital Bank as a Service built on Vault and the BankLite X modular building blocks.

BankLiteX architecture on AWS
AWS offers access to a world-class infrastructure with zero capital outlay or commitment. We believe there is no easier, quicker, or cost-effective way to launch a digital bank than on a real-time infrastructure that is always available. In addition, cloud economics can lead to a reduction in TCO by around 27%.
BankliteX leverages the power and capabilities of the AWS cloud as it is fully developed with AWS Well Architected best practices. This enables the platform to operate in a secure, reliable, and efficient manner on the AWS cloud. BankliteX is built to operate on the AWS landing zone and meets the security, compliance, and governance requirements expected by regional regulators for financial services. It brings forth the banking SaaS tenets of Thought Machine with the security, reliability, performance efficiency, cost optimization, and operational excellence of AWS infrastructure and services.
BankliteX is built with AWS serverless services, which makes it highly performant and cost effective for customers. The platform’s development on AWS Fargate and Amazon Elastic Container Service (ECS) enables the scalability and elasticity of the compute center of the BankliteX core, which eliminates the need for server provisioning and manages overhead and improves security through application isolation at the architecture design. Customers experience seamless and secure integration with Thought Machine configured with Amazon Virtual Private Cloud (VPC) and NAT Gateway.
AWS AppSync is positioned to improve system performance by automatically scaling the GraphQL API execution engine up or down to meet API request volumes and enable front-end developers to query multiple databases, microservices, and APIs with a single GraphQL endpoint.
