Description: Application isolation in the cloud refers to the practice of separating different applications and services in cloud environments to enhance security and performance. This approach allows each application to operate independently, minimizing the risk that a vulnerability in one application will affect others. Additionally, isolation facilitates resource management, as resources can be allocated more efficiently according to the specific needs of each application. Key features of isolation include network segmentation, the use of containers and virtual machines, and the implementation of strict access policies. This approach is particularly relevant in multi-cloud environments, where organizations utilize multiple cloud service providers. By isolating applications, companies can optimize their infrastructure, improve resilience against failures, and comply with stricter security regulations. In a world where cyber threats are becoming increasingly sophisticated, application isolation becomes an essential strategy for protecting sensitive data and ensuring optimal performance of cloud services.
