Abstract: Some embodiments provide a method that, at a first machine that operates at a first physical site as a primary global manager for a logical network spanning a plurality of physical sites, receives a set of ordered data describing a configuration of the logical network. The method stores, in a particular order, the received set of ordered data in a first database located at the first physical site. Through a channel between (i) the first machine and (ii) a second machine that operates at a second physical site as a secondary global manager for the logical network in case of failure of the primary global manager, the method provides the set of ordered data in the particular order for the second machine to store in a second database in the particular order. The second database located at the second physical site.

Abstract: Certain aspects described herein are directed to methods and systems for updating a status of a first process. In certain aspects, a method includes periodically examining a first table stored in a consistent and distributed database, wherein the table includes a first indication of a status of the first process and a second indication of a status of a second process and the first process and the second process are clustered for implementing functions of a distributed application in a distributed manner. The method further includes determining that the first indication has not changed during a first time period and changing the status of the first process in a second table to reflect that the first process is non-operational, wherein a different share of workload associated with the distributed application is performed by the second process as compared to when the first process was operational.

Abstract: Some embodiments provide a method for a global manager that manages a logical network spanning multiple physical sites. The method receives a set of data describing a modification to a definition of the logical network. From multiple queues that each correspond to a different one of the physical sites spanned by the logical network, the method identifying a set of queues to which to store the received set of data. The method stores the received set of data in the identified set of queues. From each respective queue in the identified set of queues, the method sends the set of data through a respective channel between the global manager and a respective local manager at the respective physical site corresponding to the respective queue.

Abstract: Certain embodiments described relate to methods and systems for adding one or more nodes to a first cluster including a first node in a computer system. A method performed by the first node comprises retrieving a first cluster configuration associated with the first cluster from a distributed database through a first database server (DBS) and creating a second cluster configuration using the first cluster configuration and information received from a second node as part of a request to join the first cluster. The method further comprises populating a first one or more local trust stores of a first one or more processes executing on the first node with a second one or more security certificates of a second one or more processes executing on the second node. The method further comprises writing the second cluster configuration to the distributed database and returning the second cluster configuration to the second node.

Abstract: Disclosed are a method and system for implementing a distributed persistent queue. To implement the queue, an API is defined that includes a command to enqueue an object onto the queue, to obtain the ordering of all objects in the queue and to remove any item from the queue. Enqueuing an object includes obtaining a unique ID for the object from a generator and then storing the object in a persistent shared log, which provides persistent storage for the queue. Obtaining an ordering of all objects in the persistent queue includes receiving for each object stored in the queue a pair of values, the first being the unique ID and the second being a sequence number from the persistent shared log. Regardless of the host computer system making the request for the ordering of objects in the queue the ordering provided to each host computer system is the same.

Abstract: Various aspects are disclosed for distributed application management using an embedded persistent queue framework. In some aspects, task execution data is monitored from a plurality of task execution engines. A task request is identified. The task request can include a task and a Boolean predicate for task assignment. The task is assigned to a task execution engine embedded in a distributed application process if the Boolean predicate is true, and a capacity of the task execution engine is sufficient to execute the task. The task is enqueued in a persistent queue. The task is retrieved from the persistent queue and executed.
