Question

Which AWS Service is PaaS in nature?

A. AWS EC2
B. AWS Lambda
C. AWS ELastic Beanstalk
D. AWS VM

Answer

C. AWS ELastic Beanstalk

Explanation

AWS Elastic Beanstalk is a Platform as a Service (PaaS) solution offered by Amazon Web Services (AWS). It simplifies the deployment and management of web applications by abstracting away the complexities of infrastructure provisioning and configuration. Here’s why Elastic Beanstalk qualifies as a PaaS:

1. Pre-Configured Environment: Elastic Beanstalk provides a pre-configured environment where developers can deploy their applications without worrying about underlying infrastructure, such as servers, operating systems, or middleware. This aligns with the core concept of PaaS, which offers a platform for application development and deployment without requiring users to manage hardware or OS-level configurations.
2. Automatic Resource Management: When you deploy an application using Elastic Beanstalk, it automatically provisions resources like EC2 instances, load balancers, and auto-scaling groups based on your application’s needs. This automation allows developers to focus on writing code rather than managing infrastructure.
3. Supports Multiple Programming Languages: Elastic Beanstalk supports popular programming languages and frameworks such as Java, .NET, PHP, Python, Ruby, Go, Node.js, and Docker. This flexibility makes it ideal for developers working across different platforms.
4. Scalability and Monitoring: Elastic Beanstalk includes built-in scalability features through auto-scaling and load balancing. It also integrates with monitoring tools like CloudWatch to ensure optimal performance of deployed applications.
5. No Additional Cost for the Platform: While users pay for the underlying AWS resources (e.g., EC2 instances or S3 storage), there are no additional charges for using Elastic Beanstalk itself. This makes it an economical choice for deploying scalable applications.

Why Not Other Options?

A. AWS EC2: EC2 is an Infrastructure as a Service (IaaS) offering that provides virtual servers for users to configure and manage themselves. It requires manual setup of operating systems, middleware, and runtime environments.
B. AWS Lambda: Lambda is categorized as Function as a Service (FaaS), enabling serverless computing where you execute code in response to events without provisioning or managing servers.
D. AWS VM: This option is incorrect because “AWS VM” is not an official AWS service name. Virtual Machines are part of IaaS offerings like EC2.

Key Features of AWS Elastic Beanstalk

• Automatic provisioning of resources like EC2 instances, load balancers, and storage.
• Built-in auto-scaling and monitoring.
• Pre-configured runtime environments for quick deployment.
• Integration with other AWS services like RDS and S3.
• Simplifies application deployment with minimal operational overhead.

In conclusion, AWS Elastic Beanstalk stands out as a quintessential example of PaaS within the AWS ecosystem, making it the correct answer to this question.
