Techniques for multi-tiered data storage in multi-tenant caching systems

A computer-implemented method, comprising:

• providing, by a computing device, a plurality of dedicated allocations and a shared allocation of a cache, a dedicated allocation of the plurality of dedicated allocations being associated with an entity of a plurality of entities, the shared allocation of the cache being available for storage to each of the plurality of entities;
• receiving, by the computing device from another computing device associated with the entity, a data request requesting data to be retrieved from the cache;
• providing, by the computing device from the shared allocation, the data requested by the data request;
• in response to identifying that the shared allocation and the dedicated allocation are full:
• evicting, by the computing device, an amount of data from the shared allocation of the cache based on identifying the amount of data as being oldest in the shared allocation of the cache;
• and
• migrating, by the computing device, an oldest instance of data from the dedicated allocation associated with the entity to the shared allocation of the cache;
• and
• moving, by the computing device, the data requested by the data request from the shared allocation to the dedicated allocation associated with the entity.
