Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Public cloud
Public cloud offers on-demand resources, pay-as-you-go pricing, and global reach without upfront capital expenditure.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
On-premises private cloud
Why it's wrong here
On-premises private cloud demands substantial capital expenditure for servers, networking gear, and cooling, with capacity planned ahead of demand. Its fixed infrastructure cannot rapidly scale to handle unpredictable global traffic spikes, and deploying data centers worldwide is cost-prohibitive. Additionally, the startup bears full responsibility for maintenance, patching, and high availability, diverting engineering time from the core application.
- ✓
Public cloud
Why this is correct
Public cloud delivers compute, storage, and networking as metered, on-demand services from a provider whose infrastructure spans multiple regions and edge locations worldwide. A startup can provision resources in seconds, scale automatically in response to traffic, and only pay for what it consumes, avoiding upfront hardware costs. Global launch is simplified via provider-managed services like CDNs and load balancers, and the operational model shifts to pay-as-you-go, ideal for uncertain demand.
- ✗
Hybrid cloud
Why it's wrong here
Hybrid cloud combines on-premises infrastructure with public cloud services, but it still requires the startup to own and operate physical servers or private nodes. This preserves a significant upfront capital investment and ongoing maintenance burden, which conflicts with the startup's need for minimal initial cost and rapid global expansion. The added complexity of integrating on-premises systems with cloud APIs, networking, and identity management further slows time-to-market.
- ✗
Multi-cloud
Why it's wrong here
Multi-cloud uses multiple public cloud providers, but for a startup it introduces redundant management overhead without addressing the core need for a simple, elastic launch platform. Each provider has its own console, billing model, IAM policies, and networking primitives, requiring extra expertise and complicating security governance. While it avoids single-vendor lock-in, it does not eliminate the need for public cloud’s operational benefits; rather, it layers on abstraction and cost-optimization challenges that can delay a global web application launch.
