Methods, systems, and techniques are disclosed for managing replication in a deployable object, such as a pod (e.g., a group of one or more containers). For example, when a pod is started in a cluster, the deployable object may start one or more virtual computer systems (e.g., containers), which may pull (e.g., initiate and run) container images from a registry server. The processing device may thus identify, such as on the file level, which container image should be pulled first. A scheduler of the one or more virtual computer systems may prioritize, based on the computed scores, a subsequent replication of archived data of the one or more virtual computer systems to be performed. The processing device may then execute, based on the prioritization by the scheduler, the subsequent replication of the archived data of the one or more virtual computer systems in the deployable object.

Chunk aware image locality scores for container images in multi-node clusters

Implementations of a routing tier for highly-available applications on a multi-tenant Platform-as-a-Service (PaaS) system are disclosed. A system includes a processing device to determine that, for an application running on the multi-tenant PaaS system and utilizing a first load balancer gear, a second load balancer gear is to be created for the application, and cause the second load balancer gear to be created. The processing device further to update the routing table to include information corresponding to the second load balancer gear and transmit the information associated with the second load balancer gear to a routing component of the multi-tenant PaaS system, the routing component to route traffic to the application via the first and second load balancer gears.

An access control engine can enable a host operating system to propagate a private resource of an isolated virtual environment, such as a container, running on the host operating system outside of the isolated virtual environment. The private resource can include, for example, a file system mounted within the isolated virtual environment. The access control engine can receive a command and launch the isolated virtual environment in response to the command. Also, in response to the command, the access control engine can interface with a kernel of the host operating system to configure the isolated virtual environment so that the private resource is accessible outside the isolated virtual environment.

Accessing file systems in a virtual environment

Implementations of a routing tier for highly-available applications on a multi-tenant Platform-as-a-Service (PaaS) system are disclosed. A method of the disclosure includes receiving, from a broker of a multi-tenant PaaS system, information related to a load balancer gear of an application running on the multi-tenant PaaS system. The information includes endpoint information indicating a location of the load balancer gear, and cartridge information identifying one or more cartridges implemented on the load balancer gear. The method further includes updating a routing table in view of the endpoint information and the cartridge information, and causing traffic to be routed to the load balancer gear in view of the updated routing table. The load balancer gear directs traffic to one or more other gears of the application.
