Serverless computing allows you to build and run applications and services without thinking about servers. Serverless applications don’t require you to provision, scale, and manage any servers. You can build them for virtually any type of application or backend service, and everything required to run and scale your application with high availability is handled for you.
Companies that build serverless applications get faster time-to-market because the core infrastructure components, like compute and databases, are offered as fully managed services by AWS. These companies also experience reduced infrastructure costs since serverless applications don’t require you to pay for idle server capacity.
Serverless applications are built using fully managed services like AWS Lambda, Amazon API Gateway, Amazon DynamoDB, Amazon S3, AWS Step Functions, and Amazon Kinesis.
