In Oracle OAC, which is a primary benefit of using cloud-based service instances?

Using cloud-based service instances, such as those offered by Oracle Analytics Cloud (OAC), provides significant advantages, one of which is scalability. Scalability refers to the ability of a system to handle growing amounts of work, or its potential to accommodate growth without compromising performance.

In a cloud environment, resources can be dynamically adjusted based on demand. This means users can expand their compute capabilities during peak usage times and reduce them during off-peak hours without needing to invest in additional physical hardware. This flexibility is particularly beneficial for businesses that experience fluctuating workloads or are looking to expand their operations quickly.

Moreover, cloud services often offer advanced tools for load balancing and resource management, further enhancing the ability to scale efficiently. An organization can adjust storage and processing power seamlessly, allowing them to accommodate more users or larger data sets as needed, thus optimizing their cost-efficiency and performance.

In contrast to this benefit, increased maintenance costs, limited data accessibility, and fixed resource allocation do not align with the advantages typically associated with cloud-based services, which focus on reducing overhead while enhancing flexibility and efficiency.
