    Abstract: Systems, methods, and computer-readable media are provided for reusing execution environments and code of serverless functions while ensuring isolation in serverless computing environments. In some examples, a method can include, in response to a first request to run a serverless function, executing, at an execution environment on a network, computer-readable code configured to perform the serverless function; after the computer-readable code has executed, modifying a pointer to an area of memory used to store a first state of the serverless function to reference a different area of memory; in response to a second request to run the serverless function, reusing, at the execution environment, the computer-readable code to perform the serverless function; and based on the pointer referencing the different area of memory, using the different area of memory to store a second state of the serverless function.

    Abstract: Systems, methods, computer-readable media are disclosed for influencing serverless function placement across hosts within a network. A method includes receiving a notification from a network component, the notification indicating a performance bottleneck in association with one or more instances of a serverless function being executed at one or more hosts of a network; initiating at least one additional instance of the serverless function in response to the performance bottleneck; and sending a message to the network component identifying the at least one additional instance of the serverless function, the network component directing network traffic based on the message.

    Abstract: A system is provided to support a serverless environment and quickly generate containers to handle requests. The system includes a first network node, a container orchestration system, and a serving node. The first network node receives an initial packet of a request from a host and sends a notification to a container orchestration system. The notification includes header information from the initial packet and signals the reception of the initial packet of the request. The container orchestration system creates one or more new containers in response to the notification based on the header information of the initial packet. The serving node instantiates the new containers, receives the request from the host, and processes the request from the host with the new containers.
