A medical company wants to perform transformations on a large amount of clinical trial data that comes from several customers. The company must extract the data from a relational databasethatcontains the customer data. Then the company will transform the data by using a series of complex rules. The company will load the data to Amazon S3 when the transformations are complete.
All data must be encrypted where it is processed before the company stores the data in Amazon S3. All data must be encrypted by using customer-specific keys.
Which solution will meet these requirements with the LEAST amount of operational effort?
A company runs an environment where data is stored in an Amazon S3 bucket. The objects are accessed frequently throughout the day. The company has strict data encryption requirements fordata that is stored in the S3 bucket. The company currently uses AWS Key Management Service (AWS KMS) for encryption.
The company wants to optimize costs associated with encrypting S3 objects without making additional calls to AWS KMS.
Which solution will meet these requirements?
A company maintains its accounting records in a custom application that runs on Amazon EC2 instances. The company needs to migrate the data to an AWS managed service for development and maintenance of the application data. The solution must require minimal operational support and provide immutable, cryptographically verifiable logs of data changes.
Which solution will meet these requirements MOST cost-effectively?
A company wants to improve the availability and performance of its hybrid application. The application consists of a stateful TCP-based workload hosted on Amazon EC2 instances in different AWS Regions and a stateless UDP-based workload hosted on premises.
Which combination of actions should a solutions architect take to improve availability and performance? (Select TWO.)
