Abstract: Modern digital platforms require infrastructure that can scale dynamically, recover quickly from failures, and operate with minimal operational overhead while supporting rapidly changing workloads. Traditional infrastructure models often require significant manual configuration and capacity planning, which can limit scalability and increase operational complexity. Serverless computing has emerged as a promising cloud computing paradigm that abstracts infrastructure management from developers, allowing applications to run in environments where the cloud provider automatically handles resource provisioning, scaling, monitoring, and fault tolerance. In serverless architectures, developers deploy small, stateless functions or services that are executed in response to events such as API requests, database updates, or messaging events. This event-driven execution model enables systems to scale automatically according to workload demand, ensuring that resources are allocated efficiently without manual intervention. Cloud platforms such as AWS Lambda, Azure Functions, and Google Cloud Functions provide built-in mechanisms for automatic scaling, load balancing, and fault recovery, which contribute to high system availability. This article examines deployment strategies for building high-availability platforms using serverless architectures, focusing on how distributed cloud services can support reliable and scalable application infrastructures. The study analyzes architectural models that combine event-driven processing patterns, stateless computing components, and distributed service orchestration to achieve resilient system designs. It also explores how serverless frameworks integrate capabilities such as auto-scaling, multi-region redundancy, and managed infrastructure services to ensure continuous system availability even under fluctuating workloads or infrastructure failures.
