DEV305 Devops Breakout Session AWS Elastic Beanstalk provides an easy way for you to quickly deploy, manage, and scale applications in the AWS Cloud. Through interactive demos and code samples, this session will teach you how to deploy your code using Elastic Beanstalk, provision and use other AWS services (Amazon SNS, Amazon SQS, and Amazon DynamoDB, AWS CodeCommit) use your application’s health metrics to tune performance, scale your application to handle millions of requests, perform zero-downtime deployments with traffic routing, and keep the underlying application platform up-to-date with managed updates.

Why did we build Elastic Beanstalk?

4. © 2017, Amazon Web Services, Inc. or its Affiliates. All rights reserved.
Developer challenges
• Complexity of deploying code, provisioning,
and managing infrastructure
• Expertise and time needed to manage and
configure servers, databases, load balancers,
firewalls, and networks
• How to automate application scaling
• Lack of consistency across teams

What is Elastic Beanstalk?
Elastic Beanstalk is an easy-to-use service for
deploying, scaling, and managing web applications
and services

Infrastructure stack
• Preconfigured infrastructure
• Single instance (dev, low cost)
• Load-balanced, Auto Scaling (production)
• Web and worker tiers
• Elastic Beanstalk provisions necessary infrastructure
resources, such as the load balancer, Auto Scaling group,
security groups, database (optional), etc.
• Provides a unique domain name for your application
(e.g., youapp.regionx.elasticbeanstalk.com)
