When companies processing large amounts of data face the need to deploy modern services in live environments, a key challenge is choosing the right technology solution. At Traveltech, where every millisecond of latency matters, WebSocket is becoming an essential tool for real-time two-way communication. The solution not only increases productivity, but also allows for better user interaction. Below, I look at how AWS capabilities can support companies to effectively deploy WebSocket in a live environment, and the business benefits of using them.

Diagnosing the problem: The need for dynamic communication ​

Today's technology systems need to be fast, reliable and scalable. For many of the Traveltech projects I work with, companies are struggling with real-time communication issues between servers and user applications. The old model of data exchange, based on traditional HTTP protocols, is insufficient when large volumes of data are required to be processed instantly. Customers are looking for solutions to maintain a constant connection that allows information to flow quickly with minimal latency.

Solution: AWS options for WebSocket ​

Choosing the right technology to implement a WebSocket service depends on the specifics of the project, technical requirements and available budget. AWS offers a wide range of tools to create efficient and scalable services that are tailored to individual business needs. From serverless models to full environment control, each option provides key functionality that makes it easy to implement WebSocket in production environments.

After analysing the available AWS tools, I present four main options for implementing WebSocket.

API Gateway with WebSocket ​

The AWS API Gateway allows the creation of a WebSocket endpoint, enabling bidirectional communication between server and client. With its built-in scaling mechanism, the API Gateway is ideal for projects where dynamic data exchange plays a key role.

Elastic Beanstalk with Node.js or Python ​

Elastic Beanstalk automates the process of deploying and managing applications. By choosing a Node.js or Python environment, you can easily support WebSocket while benefiting from simplified infrastructure management.

AWS Lambda with WebSocket ​

AWS Lambda is the ideal solution for companies looking for a serverless processing model. With the ability to automatically scale and pay for actual usage, Lambda significantly reduces operational costs while maintaining efficiency.

EC2 with WebSocket libraries ​

Amazon EC2 allows full control of the environment, which is beneficial for custom design requirements. The use of libraries such as Socket.IO allows full customisation of the WebSocket service.

Scalability and automation ​

One of the most important reasons for choosing AWS as the platform for WebSocket services is the built-in scalability. Whichever option you choose, AWS allows you to dynamically adjust your computing power to meet changing business needs. Services such as Elastic Load Balancer provide load balancing, which minimises the risk of downtime, even when traffic is heavy.

Data security: a priority for every project ​

Security is key with WebSocket services, especially in industries such as Traveltech, where the data being transmitted may contain sensitive information. AWS offers in-motion data encryption, access control (IAM) and compliance with key regulations such as GDPR and PCI DSS. This enables companies to deploy WebSocket securely, maintaining the trust of their customers.

Cost optimisation: the "pay-as-you-go" model ​

AWS differentiates itself with a 'pay-as-you-go' payment model that allows for precise cost management. By choosing serverless solutions such as AWS Lambda, companies pay only for actual resource consumption, eliminating costs associated with excessive infrastructure. This optimisation significantly increases operational efficiency, which is particularly important in a rapidly changing business environment.

Implementation example: real-time dynamic connection ​

In one Traveltech project using AWS, the client needed a WebSocket service to manage bookings in real time. The choice was to use AWS API Gateway and Lambda. This enabled the service to be scaled during peak traffic times and event processing to be automated. The implementation delivered tangible benefits in terms of increased system responsiveness, reduced operational costs and high levels of security.

Summary: AWS as the foundation for WebSocket in a production environment ​

AWS offers a wide range of options for businesses looking to implement WebSocket in their projects. From scalability and security to cost optimisation and automation, each option is tailored to suit different business needs. Implementing WebSocket using AWS is not just a technical solution, but also a key step towards innovation and competitive advantage in dynamic industries such as Traveltech. In my work, I have seen how AWS allows companies to deliver the most demanding projects, providing tangible benefits in the form of improved efficiency, lower costs and customer satisfaction.
