Serverless architecture is popular, particularly for event-driven and highly dynamic applications, owing to its simplicity, scalability, and cost-effectiveness. Ideal for developing microservices, REST APIs, data processing pipelines, and real-time applications, this architecture is well suited for asynchronous, stateless apps, and use cases with unpredictable demand surges, such as batch processing, monitoring database changes, handling data streams, implementing chatbots, managing scheduled tasks, and executing business logic.
Of these, Function-as-a-Service (FaaS) stands out as a widely adopted serverless architecture, operating on an event-driven model, executing code in stateless, ephemeral containers triggered by events. This approach offers developers precise control, enabling them to deploy applications through APIs managed by FaaS providers. Many major public cloud providers offer FaaS solutions, including AWS Lambda, Azure Functions, Google Cloud Functions, and IBM Cloud Functions. Alternatively, organisations can also implement their own FaaS using open-source platforms like Red Hat OpenShift Serverless.
Numerous industry giants including Coca-Cola, Netflix, and Bosch have leveraged serverless architecture to enhance application performance, streamline processes, and scale applications. For example, Coca-Cola applied serverless architecture to its “Freestyle” soda dispensers, which allow customers to customise their beverage choices. They use AWS Lambda for real-time telemetry data processing and reporting to ensure machine availability and efficiency. Streaming giant Netflix is also known for using serverless architecture extensively on their platform, employing AWS Lambda for various functions like user authentication, video transcoding, and data processing. This allows them to scale according to demand while only paying for the compute resources utilised. On the smart devices side, Bosch TTNA, while developing a smart HVAC solution with remote monitoring, analysis, and troubleshooting capabilities, sought a system capable of managing fluctuating workloads with minimal infrastructure management effort. To achieve this, they incorporated AWS Lambda as a core service for their cloud-connected heat pump system. This strategic choice allowed Bosch TTNA to delegate backend and infrastructure management to AWS, enabling them to concentrate on driving application innovation.
