A media company is migrating its video transcoding pipeline to AWS. The solution architect designs the system to use Amazon S3 to store raw uploads, which triggers an AWS Lambda function to process the video. The processed videos are then stored in a different S3 bucket. Additionally, the Lambda functions automatically scale out to handle thousands of concurrent uploads during peak hours and scale down to zero when there is no activity.
Which two design principles of the AWS Cloud does this architecture represent? (Select TWO).
- Services, not serversCevap
- ElasticityCevap
- CTight coupling of components
- DStatic capacity planning
- EMonolithic architecture design
Cevap
The correct design principles are 'Services, not servers' and 'Elasticity'.
The architecture demonstrates 'services, not servers' by utilizing fully managed services like Amazon S3 and AWS Lambda, which eliminates the need to provision or manage servers. It also demonstrates 'elasticity' because AWS Lambda automatically scales out to match the incoming demand of video uploads and scales back down when demand decreases.
