Serverless is a crucial evolution of cloud computing that enables more efficient use of resources such as time, money, and developer brainpower. It abstracts and automates many hands-on tasks so developers can focus on building features and services. The four fundamental principles of serverless are: hands-off (server) service, automated elastic scale, consumption-based billing, and built-in resilience and fault tolerance. Serverless is ideal for organizations of any size as it democratizes high-caliber tech that was once only available to tech giants like Google, Netflix, or Amazon.
