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.

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.

Systems and methods for detecting when related applications are running on nodes that that located near one another. An example method may comprise: analyzing beacon data to determine a physical location of a first node and a physical location of a second node; determining an application of the first node and an application of the second node are related applications; detecting the physical location of the first node and the physical location of the second node are within a proximity threshold; and generating, by a processing device, a notification indicating the related applications of the first node and the second node are within the proximity threshold.

Node proximity detection for high-availability applications

A platform executing on a computer system identifies a capability to be used by an application based on an application descriptor for the application and determines a component that provides the capability based on a component descriptor of the component. The platform identifies an additional capability to be used by the component based on the component descriptor and determines an additional component that provides the additional capability. The platform determines that the application descriptor further specifies that the application will use the additional capability provided by the additional component and determines that a single instance of the additional component will provide the additional capability to both the application and the component. The platform then groups the application, component, and additional component for deployment based on constraints associated with the application, component, and additional component.

Configuration of an application in a computing platform

Upon receiving application code and an application descriptor of an application, a platform executing on a computer system identifies a capability to be used by the application based on the application descriptor. The platform determines a component that provides the capability based on a component descriptor of the component. The platform then configures the application and the component for execution on the platform.

A computing device detects an event generated by a first component that publishes a connection endpoint, the event indicating that the connection endpoint of the first component has been modified. The computing device determines a second component that subscribes to the connection endpoint. The computing device updates a location of the connection endpoint in a data structure associated with the second component to maintain a connection between the first component and the second component.

Connection management for an application in a computing platform

A lock manager running on a machine may write a first entry for a first process to a queue associated with a resource. If the first entry is not at a front of the queue, the lock manager identifies a second entry that is at the front of the queue, and determines whether a second process associated with the second entry is operational. If the second process is not operational, the lock manager removes the second entry from the queue. Additionally, if the queue becomes unavailable, the lock manager may initiate failover to a backup copy of the queue.
