What can a SysOps Administrator do to ensure improved read times for users during the social event?
Use Amazon RDS Multi-AZ.
Add shards to the existing Redis cluster.
Offload static data to Amazon S3.
Launch a second Multi-AZ Redis cluster.
Explanations:
Amazon RDS Multi-AZ improves database availability and failover, but does not improve read performance for heavy traffic. It primarily handles disaster recovery, not read load distribution.
Adding shards to the existing Redis cluster increases its capacity by distributing the data across more nodes, which helps improve read performance and scalability, especially during high traffic periods.
Offloading static data to Amazon S3 is useful for reducing load on dynamic content but does not directly improve read performance for the database or Redis caching layer.
Launching a second Multi-AZ Redis cluster would not help in this scenario. Multi-AZ Redis provides failover and high availability, but does not address the need to increase read capacity or scalability for a high-traffic event.
From what I’ve seen, the answer is:
Add shards to the existing Redis cluster.
