AWS Solutions Architect Associate (SAA-C02)

Elastic Beanstalk

  • Used to deploy applications on AWS infrastructure
  • Platform as a Service (PaaS)
  • Automatically handles capacity provisioning, load balancing, scaling, application health monitoring, instance configuration, etc. but we have full control over the configuration
  • Free (pay for the underlying resources)
  • Supports versioning of application code
  • Can create multiple environment (dev, test, prod)
  • Supports the deployment of web applications from Docker containers and automatically handles load balancing, auto-scaling, monitoring, and placing containers across the cluster.

Web & Worker Environments

  • Web Environment (Web Server Tier): clients requests are directly handled by EC2 instances through a load balancer.
  • Worker Environment (Worker Tier): clients’s requests are put in a SQS queue and the EC2 instances will pull the messages to process them. Scaling depends on the number of SQS messages in the queue. attachments/Pasted image 20220507153757.jpg
