What is the main purpose of using segmentation in a cloud environment?

Using segmentation in a cloud environment primarily serves to apply security policies effectively. In cloud architectures, segmentation involves dividing a network into smaller, manageable sections or segments. This approach allows for more tailored and precise application of security measures, as each segment can have its own specific security policies in place.

By segmenting the network, organizations can isolate sensitive data and workloads, reducing the risk of unauthorized access and breaches. For instance, critical systems can be separated from less secure areas of the network, limiting potential attack avenues for malicious actors. Furthermore, segmentation can help in monitoring and controlling traffic between different segments, making it easier to identify and respond to security incidents.

While aspects such as speed, backup processes, and cost reduction may also benefit indirectly from segmentation, the primary focus is on enhancing security. This targeted approach helps organizations comply with regulations, protect sensitive information, and reduce the overall risk footprint in multi-tenant cloud environments.
