Which technology stack is Commerce Cloud Pro architecture instance based on?

Question

Options

• AAkamai stacked on Fastly CDN, NGINX, GlusterFS, Redis, Elasticsearch, OpenSearch, Galera
• BFastly CDN, NGINX, GlusterFS, Redis, Elasticsearch, OpenSearch, Galera
• CFastly CDN, NGINX, GaleraFS, Redis, Elasticsearch, OpenSearch, Galera
• DAkamai stacked on Fastly CDN, Apache, GlusterFS, Redis, Elasticsearch, OpenSearch, Galera

• A
  5% (1)
• B
  89% (17)
• C
  5% (1)

Explanation

Option B is correct because Adobe Commerce Cloud Pro's architecture uses Fastly CDN as its content delivery layer (not Akamai), NGINX as the web server, GlusterFS for distributed file storage, Redis for caching and session storage, Elasticsearch/OpenSearch for search, and Galera for MySQL cluster replication - this is the documented Pro instance stack.

Why the distractors fail:

• A & D incorrectly add Akamai; Commerce Cloud Pro does not stack Akamai on top of Fastly - Fastly alone is the CDN.
• D also substitutes Apache for NGINX; Commerce Cloud Pro uses NGINX, not Apache.
• C invents "GaleraFS," which does not exist - the correct distributed file system is GlusterFS (Galera is a separate MySQL clustering component).

Memory tip: Think "F-N-G-R-E-G" - Fastly, NGINX, GlusterFS, Redis, Elasticsearch/OpenSearch, Galera. Any option that swaps in Akamai, Apache, or a fictional "GaleraFS" is a trap designed to test whether you know each layer's specific technology.
