| - | **Resource Requests**, | + | |
| * A Resource Request is used to define resources such as CPU and memory at the time of **scheduling**. In other words, if the Resource Request is for 5GB, the pod scheduler will look for a node with 5GB of available RAM. A Resource Request is not a limit, as the pod can use more or less memory. | * A Resource Request is used to define resources such as CPU and memory at the time of **scheduling**.

| - | **Resource Limits**, | + | |
| * A Resource Limit allows you to set limits on resources such as CPU and memory. Different Container Runtimes react in different ways to a Resource Limit. For example, some will stop the container process if the limit is exceeded. In the case of Docker, if the CPU limit is exceeded, Docker will limit CPU usage. On the other hand, if the memory limit is exceeded, Docker will kill the container process. | * A Resource Limit allows you to set limits on resources such as CPU and memory.
