Serverless architecture is a software development approach that relies on cloud-based services to manage server infrastructure, allowing developers to focus on implementing their ideas rather than managing servers. It uses APIs as a service (SaaS) and function-as-a-service (FaaS) offerings to deliver scalable and cost-effective solutions. Serverless architectures can be applied to various types of applications, including variable-load web applications, microservices, event-driven systems, and machine-learning applications. They offer benefits such as reduced infrastructure costs, increased scalability, and improved development efficiency. Examples of serverless architecture include a next-gen voice assistant, engagement and personalization in CMS, and other use cases that demonstrate its potential to simplify software development and deployment.
