Amazon Elastic Beanstalk (EB) is a Platform as a Service (PaaS) offering from AWS that simplifies the deployment, management, and scaling of web applications. It allows developers to focus on writing code while AWS handles infrastructure provisioning, load balancing, auto scaling, monitoring, and application health management.
Elastic Beanstalk is ideal for teams that want speed, scalability, and operational simplicity without sacrificing control over the underlying AWS resources.
