Question
A company wants to run its application’s code without having to provision and manage servers.
Which AWS service will meet this requirement?
A. AWS Glue
B. AWS Lambda
C. AWS CodeDeploy
D. Amazon CodeGuru
Answer
B. AWS Lambda
AWS Lambda is the correct answer to meet the requirement of running an application’s code without having to provision and manage servers.
Explanation
Key points about AWS Lambda:
- It is a serverless compute service that allows you to upload your code and have Lambda take care of everything required to run and scale your code with high availability. You don’t need to provision or manage any servers.
- With Lambda, you can run code for virtually any type of application or backend service, all with zero server administration. Just upload your code as a ZIP file or container image, and Lambda automatically and precisely allocates compute execution power and runs your code based on the incoming request or event.
- Lambda runs your code only when needed and scales automatically, from a few requests per day to thousands per second. You pay only for the compute time you consume – there is no charge when your code is not running.
- Lambda supports multiple programming languages including Node.js, Python, Ruby, Java, Go, and more. The code you run on AWS Lambda is called a “Lambda function.”
- Use cases for Lambda include data processing, real-time stream processing, machine learning, web/mobile backends, and more.
In summary, AWS Lambda is a serverless compute service that eliminates the need to manage servers while providing automatic scaling and cost optimization based on utilization. This makes it an ideal choice for the company’s requirement to run their application code without server provisioning and management overhead. The other options listed do not provide the serverless computing capabilities of Lambda.
