Systems and methods for executing tasks adaptively

System and methods for receiving requests for executing tasks, executing the tasks while observing and gathering related performance levels, and using the observations to adapt execution of tasks to follow. The system adapts environments in which tasks are executed, thereby improving the ability of these environments to execute the tasks efficiently. As more performance data is available per a cretin type of tasks or per a specific task, the system gets closer to optimization. Performance may be affected by various parameters such as the particular execution environment used to executed the task, isolation techniques employed in keeping the tasks isolated from each other, actual code utilized for executing each of the tasks, and the usage of particular hardware components to facilitate related software. Environments, or combinations of various code and hardware components, that have proven inefficient in executing a certain task, will be replaced before executing similar tasks to follow.
