A company ingests and processes streaming market data. The data rate is constant. A nightly process that calculates aggregate statistics is run, and each execution takes about 4 hours to complete. The statistical analysis is not mission critical to the business, and previous data points are picked up on the next execution if a particular run fails.
The current architecture uses a pool of Amazon EC2 Reserved Instances with 1-year reservations running full time to ingest and store the streaming data in attached Amazon EBS volumes. On-Demand EC2 instances are launched each night to perform the nightly processing, accessing the stored data from NFS shares on the ingestion servers, and terminating the nightly processing servers when complete. The Reserved Instance reservations are expiring, and the company needs to determine whether to purchase new reservations or implement a new design.
Which is the most cost-effective design?
A multi-tenant software as a service (SaaS) customer support platform serves thousands of enterprise clients. The platform must deploy more than 5,000 customized models that use the same ML framework to classify tickets, optimize inference infrastructure costs, and maintain sub-200 ms latency. The platform must operate in a multiaccount AWS architecture that includes separate accounts for development, staging, and production environments.
Which solution will meet these requirements MOST cost-effectively?
An enterprise company is building an infrastructure services platform for its users. The company has the following requirements:
Provide least privilege access to users when launching AWS infrastructure so users cannot provision unapproved services.
Use a central account to manage the creation of infrastructure services.
Provide the ability to distribute infrastructure services to multiple accounts in AWS Organizations.
Provide the ability to enforce tags on any infrastructure that is started by users.
Which combination of actions using AWS services will meet these requirements? (Choose three.)
A company has many separate AWS accounts and uses no central billing or management. Each AWS account hosts services for different departments in the company. The company has a Microsoft Azure Active Directory that is deployed.
A solution architect needs to centralize billing and management of the company’s AWS accounts. The company wants to start using identify federation instead of manual user management. The company also wants to use temporary credentials instead of long-lived access keys.
Which combination of steps will meet these requirements? (Select THREE)
