You have a high performance compute application and you need to minimize network latency between EC2
instances as much as possible. What can you do to achieve this?
A.
Use Elastic Load Balancing to load balance traffic between availability zones
B.
Create a CloudFront distribution and to cache objects from an S3 bucket at Edge Locations.
C.
Create a placement group within an Availability Zone and place the EC2 instances within that placement
group.
D.
Deploy your EC2 instances within the same region, but in different subnets and different availability zones
so as to maximize redundancy.
Explanation:
C
Cloudfront is for Static, So B is out.
D speaks about redundancy, where are we are interested in latency.
A is out since it focuses on load balancing only.
therefore, C is obvious choice.
Great Explanation!Txs!
A Placement Group is a logical grouping of instances within a single Availability Zone and are recommended for applications that benefits from low network latency, high network throughput, or both.
Placement group don’t span across Availability Zones
