Memory Management and Request Isolation

Zoom AI Companion is designed with user privacy and system integrity in mind. The following sections explain how memory is allocated, isolated, and cleared during the lifecycle of each user request—designed to ensure data is not leaked between users or retained in memory unnecessarily.

Each user request runs in an isolated execution thread

To prevent data from leaking across requests, Zoom assigns each incoming user request to a dedicated thread. A thread is the smallest unit of execution in modern computing and includes its own call stack and memory space. This provides that the memory used to handle one user’s request is not accessible to another, even if multiple requests are processed concurrently.

Containerization provides service-level isolation across the platform

While threads isolate memory per request, Zoom also uses containerization to separate entire services. Each AI Companion service runs inside its own isolated container environment, with independent runtime dependencies, configurations, and libraries. This helps ensure consistency across deployments and adds an additional layer of infrastructure-level protection, even though it’s not intended to isolate individual user requests.

Memory is automatically reclaimed after each request completes

Once a thread finishes handling a request, all memory it used is automatically released by the underlying operating system or runtime. This default behavior ensures that memory does not persist beyond the lifecycle of the request, reducing the risk of residual data lingering in memory.

Secure coding practices further reduce residual memory risks

Zoom engineers follow secure development best practices to proactively minimize memory-related risks:

• Temporary data structures are cleared once they’re no longer needed.

• User-specific data is not stored in global or static memory.

• Languages and frameworks with automatic memory management and garbage collection are leveraged to ensure memory is reliably reclaimed by the system.

Together, these layered practices—thread-based execution, containerized service isolation, automatic memory release, and disciplined secure coding—help ensure that memory in Zoom AI Companion is managed responsibly, securely, and in alignment with enterprise-grade expectations for user data protection.
