Question

A company replaces its single server with a more powerful machine that has greater CPU, memory, and storage capacity, while keeping the total number of servers the same. This approach is called _____.

BlackTom AI · Accepted Answer

Scaling up (vertical scaling) increases the resources of an existing server — CPU, memory, and storage — rather than increasing the number of servers.

1. Relevant knowledge points and concepts
- Scaling up (vertical scaling): upgrading a single server’s hardware (more CPU, RAM, disk) to handle larger load.  
- Scaling out (horizontal scaling): adding more servers/instances to distribute load.  
- Clustering: grouping multiple servers to work together (often for redundancy or distributed processing), typically associated with horizontal scale but is a different architectural pattern.  
- Streaming: refers to continuous data processing/transfer and is unrelated to adding or upgrading server capacity.

2. Step-by-step reasoning
- The scenario states the company replaces its single server with a “more powerful machine” that has greater CPU, memory, and storage.  
- It also states the total number of servers remains the same (still one server).  
- Upgrading the capacity of an existing server while keeping the server count unchanged matches the definition of scaling up (vertical scaling).

3. Calculations / intermediate steps
- No numeric calculations are required. The logical steps are: identify change in resources (increase) + identify change in server count (none) → classify as vertical scaling (scaling up).

4. Why the correct answer is correct
- “Scaling up” directly describes replacing a server with a more powerful one to increase capacity without changing the server count. The core idea of vertical scaling is exactly this: move to a beefier machine to support heavier workloads.

5. Why the other options are incorrect
- Scaling out: would require adding more servers (increasing the number of nodes), which contradicts “keeping the total number of servers the same.”  
- Streaming: unrelated; pertains to continuous data flow/processing, not server count or capacity changes.  
- Clustering: implies using multiple machines to work together; while clustering can improve performance and redundancy, it requires multiple servers and is not simply replacing one server with a more powerful one.

6. Conclusion
The correct answer is Scaling up, which matches the provided answer.

A company replaces its single server with a more powerful machine that has greater CPU, memory, and storage capacity, while keeping the total number of servers the same. This approach is called _____.单项选择题
