Bandwidth management of memory through containers

A computer program product for managing memory bandwidth usage in containers, the computer program product comprising:

• one or more computer-readable storage media and program instructions stored on the one or more computer-readable storage media, the program instructions comprising:
• in response to instructions to detect execution of one or more software containers by the software container engine, instructions to generate a monitoring layer;
• instructions to monitor, by the generated monitoring layer, a memory bandwidth use value associated with each of the executed software containers;
• instructions to calculate an average memory use value associated with each executed software container for one or more periodic intervals;
• in response to the calculated average memory use value being above a threshold associated with a monitored software container of the executed containers, instructions to suspend the monitored software container for a suspend time duration, wherein the memory bandwidth use value associated with the suspended software container does not increase;
• and
• instructions to reactivate the suspended monitored software container based on the suspend time duration expiring.

A computer system for managing memory bandwidth usage in containers, the computer system comprising:

• one or more computer processors;
• one or more computer-readable storage media;
• program instructions stored on the computer-readable storage media for execution by at least one of the one or more processors, the program instructions comprising:
• instructions to receive software container properties from a software container engine, wherein the software container properties include at least a max memory bandwidth use value;
• in response to instructions to detect execution of one or more software containers by the software container engine, instructions to generate a monitoring layer;
• at periodic time intervals, instructions to monitor, by the generated monitoring layer, a memory bandwidth use value associated with each of the executed software containers;
• for each periodic time interval, instructions to calculate an average memory use value associated with each executed software container;
• in response to the calculated average memory use value being above a threshold associated with a monitored software container of the executed containers, instructions to suspend the monitored software container for a suspend time duration, wherein the memory bandwidth use value associated with the suspended software container does not increase;
• and
• instructions to reactivate the suspended monitored software container based on the suspend time duration expiring.
