In cloud computing, what does the term 'scalability' refer to?

The ability to increase or decrease resources as needed
The safety of data stored in the cloud
The cost-management strategy for cloud services
The level of compliance achieved by a cloud provider

The correct answer is: The ability to increase or decrease resources as needed

Scalability in cloud computing specifically refers to the capability of a cloud environment to adjust resources based on demand. This means that as a workload increases, additional resources can be allocated seamlessly to manage the extra load without disrupting service. Conversely, during periods of lower demand, resources can be reduced to avoid unnecessary costs. This dynamic adjustment is one of the fundamental advantages of cloud computing, enabling businesses to respond quickly to changing needs and optimize performance while managing costs effectively. The other concepts mentioned, such as data safety, cost-management strategies, and compliance levels, are important aspects of cloud service usage but do not encompass the core meaning of scalability. Data safety pertains to security measures in place to protect information, cost management focuses on budget and expenditure related to cloud usage, and compliance deals with adhering to regulations and standards set forth in the industry. While all these elements are vital for a successful cloud strategy, they are separate from the principle of scalability itself.
