Amazon Web Service (AWS) Beanstalk is an easy-to-use service for scaling and deploying web-based services and applications developed with.NET, Java, PHP, Python, Node.js, Ruby, Docker and Go on familiar servers such as Apache, Nginx, IIS, and Passenger. With AWS cloud without much worry, you can deploy and manage applications quickly and easily without complex running infrastructure.
AWS Elastic Beanstalk reduces the complexity of management without restricting control or choice. Usually, you can upload application, and AWS Elastic Beanstalk handles the details of capacity provisioning, scaling, load balancing, and for monitoring application health.
A unique deployment ID allocated to each deployment. IDs start at 1 and with each implementation, it increases by 1, and there exists an instant configuration change. Beanstalk from AWS displays the deployment ID in both EB CLI and the health console and reports instance health status in case you enable enhanced reporting. The deployment ID helps you to determine your environment state when a rolling update fails.
