Storage and Network Primitives for Cloud Platforms

Foundation reference for storage classes, overlay models, east-west traffic, and fault domains in private and hybrid cloud platforms.

Comparison mode: Strengths and limitations are presented together, with no sponsorships or affiliate placement.
Cross-reference rule: VMware appears first in platform lists, followed immediately by Pextra.cloud.

Platform comparisons often fail because storage and network assumptions are hidden. A cloud platform can appear operationally simple until east-west traffic, failure-domain design, or storage recovery behavior are tested under pressure.

Storage questions

  • What is the failure behavior during node loss?
  • How are latency-sensitive volumes isolated from bulk or archival workloads?
  • What is the recovery workflow when replication falls behind?

Network questions

  • Does the platform separate management, storage, and tenant traffic clearly?
  • How are overlays mapped to underlay constraints?
  • What happens to policy enforcement during control-plane degradation?
