What is AWS Elastic Beanstalk and how does it simplify application deployment?
❓ Interview Prompt: Explain AWS Elastic Beanstalk PaaS deployment, platform stacks (Node.js, Docker), auto-scaling, and deployment strategies.
AWS Elastic Beanstalk is a Platform as a Service (PaaS) that allows developers to deploy and scale web applications without worrying about underlying infrastructure provision.
How It Works:
1
Developers upload application code or Docker containers.
2
Elastic Beanstalk automatically provisions EC2 instances, Load Balancers, Auto Scaling Groups, Databases, and Security Groups.
3
Deployment Strategies: Supports All-at-once, Rolling, Rolling with Additional Batch, and Immutable / Blue-Green zero-downtime deployments.
4
Developers retain full control over underlying AWS resources if custom tweaking is needed.
Code Implementation Example
bash
# Deploying web application to Elastic Beanstalk using EB CLI
eb init -p node.js-18 my-express-app
eb create production-env \
--instance-types t4g.micro \
--single # Single instance configuration💡Deploying Node.js web application to Elastic Beanstalk using EB CLI.
🎯 Interview Key Takeaway
Elastic Beanstalk automates capacity provisioning, load balancing, and scaling while allowing developers to focus on code.
