AWS SAP-C02 · Question 65 · Domain 4.2: New Architecture Design
An enterprise is migrating its on-premises data center to AWS. They have a legacy mainframe application that cannot be migrated. However, the new microservices built on AWS need to query data from the mainframe with sub-millisecond latency. The mainframe and AWS are connected via AWS Direct Connect. How can the architect meet the latency requirement?
Answer options:
Use Amazon ElastiCache in the AWS region to cache mainframe data.
Deploy AWS Outposts in the on-premises data center and host the microservices on it.
Upgrade the Direct Connect connection to 100 Gbps.
Use AWS Local Zones.
