A method may include detecting, by an integrated development environment (IDE), a code modification of an Infrastructure as Code (IaC) module; identifying a resource modification associated with the code modification; determining an estimated cost associated with the resource modification; and visually rendering information reflecting the estimated cost in a visual association with the code modification.

A system and method for configuring components added to a network is disclosed. The method includes determining, by a host, that network identifying information of a plurality of networks to which the host is connected is unknown, listening for messages on the plurality of networks to obtain network identifying information for respective networks, receiving a message on a network of the plurality of networks, the message including a network identifier and a set of configuration settings, and configuring a network connection of the host for the network in view of the network identifier and the set of configuration settings from the message.

Systems and methods for identifying memory devices for swapping virtual machine memory pages. An example method may comprise: identifying, by a processing device, a workload type associated with a workload being executed by a computer system; identifying a memory device associated with the workload type; evaluating a memory pressure metric reflecting a period of time during which an application being executed by the computer system has been blocked by a memory allocation operation; and responsive to determining that the memory pressure metric exceeds a threshold value, allocating a memory block on the identified memory device.

Aspects of the disclosure provide for mechanisms for securing virtual machines in a computer system. A request for a resource is received by a processing device. The request is initiated by a guest application. A determination is made by the processing device of whether an initialization of the guest application is completed. In response to a determination that the initialization of the guest application is completed, at least one system call associated with the request initiated by the guest application is blocked to reject execution of the request for the resource.

Systems and methods for managing interrupts generated by network interface controllers. An example method may comprise: responsive to determining that a memory pressure metric in a computer system does not exceed a threshold value, disabling interrupts that signal completion of a packet transmission by a network interface controller; transmitting a plurality of data packets by the network interface controller; and responsive to detecting that the memory pressure metric exceeds the threshold value, releasing a memory buffer allocated to a data packet of the plurality of data packets.

A method may include detecting, by an integrated development environment (IDE), a code modification of an Infrastructure as Code (IaC) module; identifying a resource modification associated with the code modification; determining an estimated cost associated with the resource modification; and visually rendering information reflecting the estimated cost in a visual association with the code modification.

An example method of providing a notification includes comparing a first code segment stored in a first page with a second code segment stored in a second page, before deployment of the second page in a production environment. The first page may be deployed in the production environment, and the second page may be a different version of the first page. The method also includes detecting a user interface (UI) modification based on comparing the first code segment with the second code segment. The method further includes providing a notification of the UI modification.

A system and method for configuring components added to a network is disclosed. The method includes determining, by a host, that network identifying information of a plurality of networks to which the host is connected is unknown, listening for messages on the plurality of networks to obtain network identifying information for respective networks, receiving a message on a network of the plurality of networks, the message including a network identifier and a set of configuration settings, and configuring a network connection of the host for the network in view of the network identifier and the set of configuration settings from the message.

Implementing multiple load balancer drivers for a single load balancer is disclosed. A first request directed to a load balancer to load balance requests based on a first request selection instruction is received. A first particular load balancer driver is selected from a plurality of load balancer drivers based on a load balancer table that correlates request selection instructions to corresponding load balancer drivers of the plurality of load balancer drivers. Subsequent requests that are encompassed by the first request selection instruction directed to the load balancer are caused to be load balanced by the first particular load balancer driver.

A system and method for configuring components added to a network is disclosed.
