Multi-layer autoscaling for a scale-up cloud server

A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a device to cause the device to perform operations comprising:

• detecting whether a performance of a system, which executes an application using a layered software environment that provides one or more lower layer software environments below an upper layer software environment, reaches a target performance;
• horizontally scaling the layered software environment, including scaling a first layer software environment in the layered software environment in response to the performance of the system not reaching the target performance and scaling a second layer software environment that is above the first layer software environment in the layered software environment in response to the performance of the system not reaching the target performance despite the first layer software environment being scaled;
• and
• vertically scaling hardware resources used for executing the layered software environment in the system in response to the performance of the system not reaching the target performance based on a response time of the application and a central processing unit (CPU) usage rate before scaling of the first layer software environment based on a lock contention.
