Cloud Native Payment Systems - The Future of Payments

Consumer purchasing habits are changing; speed and convenience are paramount. But this growing volume of financial data highlights the need for modern infrastructure to handle it securely.

The payments industry is evolving at a rapid pace, with more and more consumers choosing to make purchases online or via mobile devices. To keep up with these changes, businesses are turning to cloud-native payment systems that can offer greater flexibility, scalability and security. Amazon Web Services (AWS) provides a range of architectures and services that can help businesses build and deploy these systems. In this blog, we will explore how AWS is leading the way in cloud-native payment systems and what the future of payments might look like.

What are cloud-native payment systems?

Cloud-native payment systems are built on cloud infrastructure and are designed to be flexible, scalable and secure. They use microservices architecture, which breaks down complex applications into smaller, more manageable components that can be deployed and updated independently. This approach allows businesses to innovate faster, respond to changing customer needs and improve the user experience.

Benefits of AWS for cloud-native payment systems

AWS provides a range of benefits for building and deploying cloud-native payment systems, including:

  • Scalability:  AWS provides elastic compute, storage and database services that allow businesses to scale their payment systems up or down based on demand. This means that businesses can easily handle increased traffic during peak periods without having to invest in additional infrastructure.
  • Security:  AWS provides a range of security services, including encryption, identity and access management, and compliance certifications, that help businesses protect sensitive payment data.
  • Cost savings:  AWS provides a pay-as-you-go pricing model, which means businesses only pay for the resources they use. This can result in significant cost savings compared to traditional on-premises infrastructure.

Building cloud-native payment systems on AWS requires a well-designed and scalable architecture that can handle high volumes of transactions while maintaining security and reliability. Some best practices for building AWS architectures for cloud-native payment systems:

Decouple services

Decoupling services is a key best practice for building AWS architectures for cloud-native payment systems. This means breaking down the payment system into smaller, independent services that can communicate with each other using APIs or messaging systems like Amazon SNS or SQS. This allows each service to scale independently, ensuring that the system as a whole can handle high volumes of transactions.

Use managed services

AWS provides a wide range of managed services that can be used to build cloud-native payment systems, including AWS Lambda, Amazon API Gateway, Amazon SNS, Amazon SQS and Amazon DynamoDB. Using managed services allows businesses to focus on building the payment system's core logic, while AWS handles the underlying infrastructure and scaling.

Implement security best practices

Security is crucial for any payment system, and AWS provides a range of security features that can be used to secure cloud-native payment systems. These include IAM roles, VPCs and encryption options like Amazon KMS. It's important to implement security best practices at every layer of the architecture to ensure that the payment system is secure and compliant with regulations.

Use caching and content delivery networks (CDNs)

Caching and CDNs can significantly improve the performance of cloud-native payment systems on AWS. Services like Amazon CloudFront and Amazon ElastiCache can be used to cache static content and API responses, reducing the load on the backend services and improving response times for users.

Monitor and test

Monitoring and testing are critical for ensuring that AWS architectures for cloud-native payment systems are working as intended. AWS provides a range of monitoring and testing tools, including AWS CloudTrail, AWS Config and AWS X-Ray. These tools can be used to monitor the payment system's performance, identify issues and test changes before deploying them to production.


Reference architecture

  • The user accesses the interface and establishes a connection to the application.
  • The user verifies their identity through Amazon Cognito and provides payment details.
  • The request is verified and checked by AWS Shield and AWS Web Application Firewall.
  • The credit card information is transferred to the front-end application and then forwarded to the payment processor.
  • The payment processor API generates a credit card token and sends it back to the front-end application.
  • The front-end application sends the token to the VPC Gateway Endpoint.
  • The REST API receives the token and transaction data.
  • The application's logic stores the transaction in Amazon Aurora.


The future of cloud-native payment systems

The future of payments is likely to be dominated by cloud-native payment systems. These systems offer greater flexibility, scalability and security than traditional on-premises infrastructure, making them ideal for businesses looking to innovate and stay ahead of the competition. As more and more consumers choose to make purchases online or via mobile devices, businesses will need to adapt and embrace cloud-native payment systems to remain competitive. With AWS leading the way in cloud-native architectures and services, businesses have everything they need to build and deploy the payment systems of the future.
