摘要： 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.

摘要： In one aspect, the present disclosure relates to a method comprising: receiving, at a client device, information from a node manager about a plurality of nodes in a computer cluster, the information comprising a network address associated each of the plurality of nodes and sending, by the client device, a request to a load balancer to access a first node from the plurality of nodes, the request comprising a first URL including an encoded representation of the network address associated with the first node. The load balancer is configured to determine the request should be routed to a first network address based on decoding the URL, the first network address associated with a first node from the plurality of nodes and forward the request to the first node in response to the determining.

摘要： A method for maintaining server persistency, including: (a) receiving, by an intermediate entity, a first session request from client to receive a service from a server out of a plurality of servers that are connected to the intermediate entity; (b) selecting a server out of the plurality of servers and directing to the selected server information indicative of the first session request; (c) receiving a response of the selected server to the information indicative of the first session request; (d) analyzing the response of the selected server, to provide an analysis result indicative whether the response includes code to be executed by the client and includes at least one instruction that facilitates sending, by the client, another request, to receive a service from a server out of the plurality of servers; (e) modifying, based on the analysis result, the code by adding information that will cause the client to send a selected server identifier in association to the sending of the other request; and (f) sending a modified response to the client, wherein the modified response includes the modified code.

摘要： An example method for storing data includes providing a plurality of physical storage pools, each storage pool including a plurality of storage nodes coupled to a network. The method also includes mapping a partition of a plurality of partitions to a set of physical storage pools, where each physical storage pool of the set of physical storage pools is located in a different availability zone, and the storage nodes within an availability zone are subject to a correlated loss of access to stored data. The method further includes receiving a data management request over the network, the data management request being associated with a data object. The method also includes identifying a first partition of the plurality of partitions corresponding to the received data management request and manipulating the data object in the physical storage pools mapped to the first partition in accordance with the data management request.

摘要： Techniques for creating a persistent connection between client devices and one or more remote computing resources, which may form a portion of a network-accessible computing platform. This connection may be considered “permanent” or “nearly permanent” to allow the client device to both send data to and receive data from the remote resources at nearly any time. In addition, both the client device and the remote resources may establish virtual channels over this single connection. If no data is exchanged between the client device and the remote computing resources for a threshold amount of time, then the connection may be severed and the client device may attempt to establish a new connection with the remote computing resources.

摘要： Disclosed is a system for servers to redirect client requests to other servers in order to distribute client traffic among the servers. A client is assigned to a server although the client may be unaware of that assignment. When the client accesses a server, a server possibly identified to the client by a name service, the server checks the client's assignment. If the client is not assigned to this server, then in some scenarios this server redirects the client to its assigned server. The client responds by sending its request to the assigned server. In other scenarios, the first server accessed by the client proxies the client's traffic to the assigned server. A database is kept of client-to-server assignments. If the present load distribution is less than ideal (e.g., clients are assigned to an unavailable server), then the assignment database is updated to reflect how the load should be distributed.

摘要： A server set may provide a document service to one or more clients, and may be configured to do so in view of various considerations such as availability, fault tolerance, flexibility, and performance. Presented herein are document service architectures that involve partitioning the document set into at least two document ranges, and configuring respective servers of the server set to host one or more agents to which are respectively assigned one or more document ranges. A request for an operation involving at least one document may be routed to a server hosting an agent managing the document ranges of the documents involved in the operation. Moreover, respective servers may retain detailed information about neighboring servers (e.g., according to a logical or physical proximity) and scant information about distant servers, thereby avoiding both the extensive information exchange of highly informed network architectures and the inefficiency of uninformed routing algorithms.

摘要： Various embodiments are described herein for systems and methods that can be used to determine a destination location in a network fabric. In one example embodiment, the method comprises receiving an application server attribute at a fabric controller from a source port, generating at the fabric controller a destination location based on the application server attribute and mapping information stored on the fabric controller, and transmitting the destination location to the source port, where the source port transmits packetized data to a destination location based on the destination location.

摘要： Systems and methods to bind a client with a server are provided. A particular method includes establishing a connection between a server and a client. A list of best-fit server IP addresses is received at the client via the connection. A determination is made whether the server is identified in the list of best-fit server IP addresses. When the server is not identified in the list of best-fit server IP addresses, the connection to the server is terminated.
