AWS Elastic Beanstalk



Deploy and Scale Web Applications. Developers focus on writing codes and don’t need to worry about infrastructure .It’s a managed service from AWS, like AppEngine from GCP

( GCP Equivalent Offering is : App Engine ).

It provides support for various languages like Java, NodeJS, Python, PHP , Single Container Docker, multi container Docker and Preconfigured Docker

Elastic Beanstalk helps in

Configuring Load Balancer ( ELB ) and Auto Scaling Group ( ASG )

Configuring EC2 ( Elastic Cloud Compute VM )

Creating S3 Bucket and also provisioning RDS instance for storing the data

Integrates with CloudTrail ( for auditing events ) and CloudWatch ( for Monitoring and logging) and also comes with internal dashboard

Beanstalk Components

Application Version : Deploy the code and create a version to deploy in environment

Environment : Webserver and Worker environments. Can offload long running tasks to Worker tier environments.

Configurations: Configure logs to get stored in S3, Configure X-Ray daemon to instrument the application trace etc, configure logs to stream into Cloud Watch for monitoring and also configure cloud watch alarms, ELB (Elastic Load Balancer )and ASG etc.

RDS also can be configured along with Elastic Beanstalk. But if EBS got deprovisioned, RDS provisioned along with this will also go off.

Once we chose the load balancer ( Application/Network/Gateway ) for Elastic Beanstalk, it can’t be altered later

To create a sample app in Elastic Beanstalk

Navigate to EBS section in aws console and click on applications

Then provide application name and choose the required platform

Choose the required platform

Can use sample application code or upload your own code

Click on create Application, it will provision the app as below

EBS will create buckets in S3 to hold code and configuration data. It also provisioned Security Group and Elastic IP for deploying the application. All this can be viewed in Events section


CloudFormation is Infrastructure as Code to provision resources in AWS. It’s AWS native infrastructure tool.

It’s similar to Terraform ( IAC) tool to provision resources, as used in GCP

Elastic Beanstalk relies on CloudFormation to provision other AWS Services

Configuration for provisioning resources can be defined in a configuration file with “.config” extension which resides under .ebextensions folder in CloudFormation

Beanstalk Deployment Modes

EBS Deployment modes comes in 4 categories

All At Once : Fastest, but there will be a downtime

Rolling : Rolling updates with minimal capacity

Rolling with Additional Batch : Rollback with minimal cost

Immutable : Rollback quickly , but expensive. Full capacity

Elastic Beanstalk Lifecycle Management

EBS Lifecycle setting helps to maintain versions and clear/delete the old version from EBS. We can set the max no of versions to be maintained and also option to delete/retain the source bundle in S3.

Elastic Beanstalk Cloning

Clone an environment with exact configuration.

Even after cloning the EBS, one can not change the loadbalancer type. User can create a new environment except LB and choose the required LB

EB Command Line Interface

In addition to AWS CLI to perform commands, user can install EB CLI to work with Elastic Bean Stalk
