How should a SysOps administrator deploy the EC2 instances to meet these requirements?
Use a cluster placement group in a single Availability Zone.
Use a cluster placement group across multiple Availability Zones.
Use a partition placement group in a single Availability Zone.
Use a partition placement group across multiple Availability Zones.
Explanations:
A cluster placement group in a single Availability Zone is ideal for high-performance computing (HPC) applications requiring low latency and high network throughput, as it ensures that instances are physically located close together on the network. This minimizes latency and maximizes bandwidth.
A cluster placement group across multiple Availability Zones introduces network latency and can reduce throughput due to the longer distances between instances in different zones, which is not suitable for applications that require minimum latency and maximum throughput.
A partition placement group in a single Availability Zone can improve fault tolerance by isolating failures to a single partition, but it does not optimize for low latency and high throughput like a cluster placement group does. The instances may not be as closely networked together.
A partition placement group across multiple Availability Zones is designed for high availability and scalability rather than low latency and high throughput. This setup would increase latency and decrease throughput because instances are not in close proximity, which is contrary to the requirements of the HPC application.
In my experience, the answer is:
Use a cluster placement group in a single Availability Zone.
