A customer is concerned about vendor lock-in when adopting cloud services. Which strategy should a sales associate recommend to mitigate this risk?

The consolidation ratio shows how many physical servers were replaced, directly translating to hardware, power, and space cost savings.
A prospect asks what 'high availability' means in a cloud context. The best answer is:
Answer: The system is designed to minimize downtime through redundancy and failover
High availability refers to designing systems with redundant components and automatic failover so downtime is minimized, though not necessarily zero.
When a cloud provider offers a 99.9% uptime SLA, approximately how many hours of downtime per year does that represent?
Answer: About 8.7 hours
99.9% uptime (three nines) allows approximately 8.76 hours of downtime per year (0.1% × 8,760 hours).
Which cloud service feature automatically distributes incoming application traffic across multiple servers to prevent any single point of overload?
Answer: Load balancing
Load balancing distributes incoming requests across multiple backend servers, improving availability and preventing bottlenecks.
