Abstract: A method may include receiving a first definition of an object type from a first software component and a second definition of the object type from a second software component. The object type may be labeled by an ID. The method may further include storing, in a dynamic graph, a node labeled by the ID, and storing, in a type definition repository external to the dynamic graph, the first definition of the object type and the second definition of the object type. The method may further include receiving, from the first software component, a modified first definition of the object type. The method may further include replacing, in the type definition repository and using the ID, the first definition of the object type with the modified first definition, and transmitting, to the second software component, a message indicating a need to lookup, by the ID, the modified first definition.

Abstract: Technologies are disclosed herein for transport layer network data authentication. A token packet is attached to network data sent from a client software application to an application server at the transport layer. The token packet can be generated based on a temporary token key obtained from a token service. The token packet can include a signature of the network packet payload. The network packet with the attached token packet can be received at an edge device in the network where the application server resides before reaching the application server. The edge device can verify the authenticity of the network packet by verifying the signature contained in the token packet. If the verification is successful, the edge device can forward the network packet to the application server. If the verification fails, the edge device can block further transmission of the network packet.

Abstract: Change management in a relational database may be implemented by indexing changes by copying the database to a new revision when a change is made to one or more items in the database. The new revision may be committed as a single unit and all changes stored together under a single revision. Database users may be notified of the new revision that is available for use. Software configuration issues may be simplified through the use of a configuration language that separates the logical configuration between software components from the specific configuration of those components. Secure data center administration may be handled through the use of control hosts.

Abstract: Methods and apparatus for transmitting stream logging data via a web browser are disclosed. A client device that implements a web browser may open a time-limited socket that remains open for a predetermined period of time. The client opens a socket to a server for bidirectional communication, which the server can transmit data across. The server sends streaming logging data to the client via the client-side socket and server side socket. Upon occurrence of an event, the server sends instructions that cause the client to keep the client-side socket open. Upon receipt of the instructions from the server the client resets a timer associated with the time-limited client side socket to keep the client-side socket open for an additional predetermined period of time.
