Pre-building containers

One or more computer-readable storage media having stored thereon multiple instructions that, when executed by one or more processors of a computing device, cause the one or more processors to:

• receive an indication of usage sessions scheduled, and future times respectively associated with the usage sessions;
• build a container for each of the respective usage sessions, each container comprising a process container or a virtualized container and containing data relevant to the corresponding usage session, the data including a document associated with the corresponding usage session and an application configured to operate on the document;
• add each of the containers to a container store;
• retrieve a container for a specific meeting scheduled by a meeting scheduling system;
• and
• provide the container for the specific meeting to a host system comprising a host operating system on the basis of the host system participating in the specific meeting, the host system executing the container for the specific meeting by providing namespace isolation for the container to access a file system of the host operating system and by virtualizing access to memory and a processor of the host system.

A computing device comprising:

• one or more processors;
• and
• computer-readable storage medium having stored thereon multiple instructions that, responsive to execution by the one or more processors, cause the one or more processors to:
• receive an indication of a meeting scheduled for a future time by a meeting scheduling system, the indication corresponding to a document associated with the meeting and comprising content related to the meeting;
• parse metadata associated with the meeting;
• build a container for the meeting by, based on the parsed metadata, including in the container the document and a program configured to operate on the document, the container comprising an isolated usage session configured for the corresponding meeting, the container comprising a process container within which the program can execute;
• add the container for the meeting to a container store;
• and
• provide, to a host system, the container for the meeting, the host system comprising a host operating system, the host system executing the container for the meeting by providing namespace isolation for the container to access a file system of the host operating system and by virtualizing access to memory and a processor of the host system, wherein the program operates on the document in the container while executing within the container.
