About the Flashcards
Flashcards for the CompTIA DataX exam give you a quick way to revisit essential cloud computing concepts you're likely to see on test day. Each card breaks down definitions and core functions of service models, major providers, scaling strategies, and networking components so you can recall the right term under pressure.
Use this deck to reinforce how virtualization, containers, and serverless architectures fit together; why object storage, data warehouses, and read replicas matter for data management; and how auto-scaling, load balancing, and fault-tolerant designs keep applications responsive. Concise explanations help translate theory into the practical scenarios the exam often presents.
Topics covered in this flashcard deck:
- Cloud service models
- Scaling & elasticity
- Virtualization & containers
- Storage & databases
- Networking & delivery
- Reliability & fault tolerance
