For a cloud-native application that requires frequent scaling, which ECS node type is most suitable?

Question

Options

• AFixed-capacity high-memory nodes
• BScalable general-purpose compute nodes
• CSingle-threaded compute nodes
• DFixed-capacity storage-optimized nodes

• A
  6% (1)
• B
  82% (14)
• C
  12% (2)

Explanation

Scalable general-purpose compute nodes (B) are ideal for cloud-native applications because they balance CPU, memory, and network resources while supporting dynamic horizontal scaling - the core requirement when workloads fluctuate unpredictably. Options A and D (fixed-capacity nodes) contradict the "frequent scaling" requirement entirely: "fixed-capacity" means you can't elastically add or remove resources, making them poor fits for variable demand. Option C (single-threaded compute nodes) creates a throughput bottleneck, since containerized cloud-native workloads are typically designed to exploit parallelism across multiple threads and cores.

Memory tip: Think "G = General = Grows with demand." Cloud-native means cloud-flexible - whenever you see frequent scaling, eliminate anything labeled fixed or single-threaded first.
