What does a network isolation strategy achieve in a cloud architecture?

1. Improves data analysis capabilities

2. Protects data integrity by separating workloads

3. Increases hardware utilization

4. Reduces latency in communications

The correct answer is: Protects data integrity by separating workloads

A network isolation strategy is primarily aimed at enhancing security within cloud architectures by creating defined boundaries between different workloads or applications. By isolating networks, the strategy helps protect sensitive data and resources from unauthorized access and potential attacks. This separation ensures that even if one workload is compromised, the impact on other isolated workloads is minimized. Separating workloads can also assist in achieving compliance with various regulatory standards that mandate strict controls over access to sensitive data. In a cloud environment, this is particularly crucial, as multiple tenants and workloads often share the same physical infrastructure. Therefore, network isolation helps to maintain data integrity by ensuring a clearer demarcation of access and interaction policies. The other choices focus on aspects that network isolation does not primarily address. Data analysis capabilities relate to the ways data is processed and analyzed, hardware utilization refers to the efficiency of physical resources, and latency is concerned with the speed of data transmission, none of which are the main objectives of a network isolation strategy.
