Question
A company has data lakes designed for high performance computing (HPC) workloads.
Which Amazon EC2 instance type should the company use to meet these requirements?
A. General purpose instances
B. Compute optimized instances
C. Memory optimized instances
D. Storage optimized instances
Answer
The best Amazon EC2 instance type for high performance computing (HPC) workloads and data lakes is:
B. Compute optimized instances
Explanation
Compute optimized EC2 instances are designed to deliver high performance for compute-intensive workloads. They provide a high ratio of vCPUs to memory and are optimized for applications that benefit from high compute power.
Key features of compute optimized instances include:
- High performance processors (e.g. Intel Xeon, AMD EPYC)
- Sustained all-core turbo frequencies
- Large L3 caches
- High memory bandwidth
- Enhanced networking with ENA (up to 100 Gbps)
Compute optimized instances are ideal for batch processing, distributed analytics, high-performance computing (HPC), scientific modeling, dedicated gaming servers, machine learning inference, and other compute-intensive applications.
The other EC2 instance types are less suitable for HPC workloads:
- General purpose instances provide a balance of compute, memory and networking resources. They are better for diverse workloads such as web servers and small databases.
- Memory optimized instances are designed for memory-intensive applications such as high performance databases, distributed web scale in-memory caches, and real-time big data analytics. They have a high ratio of memory to vCPU.
- Storage optimized instances are designed for workloads that require high, sequential read and write access to very large data sets on local storage. They are better for applications like NoSQL databases, in-memory databases, scale-out transactional databases, data warehousing, and Elasticsearch.
So in summary, compute optimized EC2 instances provide the best performance for HPC and compute-heavy data lake workloads, as they are purpose-built for applications requiring high compute power.
