Methods and apparatus are disclosed to provide a sandboxed code execution in a virtualized environment. The example apparatus includes a closure service to receive an input related to code for execution and generate a closure to trigger execution of the code within the apparatus. The example apparatus includes an image service to monitor container hosts and associated container images. The example image service is to expedite code execution on a container host having a prepared container image and to generate an execution container image on a second container host not having a container image. The container host is to form a host environment for the prepared container image. The prepared container image is to spawn a container to execute the code. The container is to execute the code and keep code execution and result inside the container. The code execution and result inside the container do not affect operation of the apparatus.
