A client can request, from a server, files needed to run a web application at the client (e.g., via a client web browser). The server can serve the requested files to the client along with a file identifier for each of the files. The file identifier for a respective file can be generated dynamically based on the contents of the respective file. When the requested files and the file identifiers are received at the client, the client can dynamically generate a validation code based on the file identifiers. Similarly, at the server, a verification code can be generated dynamically based on the file identifiers transmitted. To verify that the client has the appropriate files for running the web application, the server can compare the validation and verification codes. If the two codes match, then it can be verified that the client has the appropriate files for the web application.

Dynamic verification of application data using deterministic functions

Access to an information technology resource may be provided to a user involved in a data center construction project. The information technology resource may be located on a secure network, but be made accessible to the user through one or more unsecure networks. Access to the information technology resource aids the user in performing tasks related to data center construction, such as tracking the receipt and installation of equipment.

Mobile work platform for remote data centers

Techniques are described for providing selective access to secure physical and/or logical domains for agents that need to perform work in those domains. A work order will detail work to be performed by one or more agents, such as a technician or software agent, that will need access to protected domains to perform the work, and the tasks requiring agent access to the protected domains are controlled and completion thereof verified. Interaction with a monitoring/security system for the protected physical domains occurs to selectively allow access of the agent to the protected domain(s) as needed for the tasks. Other aspects of the disclosure are described in the detailed description, figures, and claims.

Protected domain workflow access control system

Methods and systems for a topology service providing an interface for specifying a topology and answering queries regarding the topology. Further, the topology service may create, from a specified topology, a directed acyclic graph and corresponding closure table. The topology service may also provide an interface for receiving metadata regarding the topology. In this way, the topology service, based at least in part on connections between nodes in the entries of the closure table and based at least in part on the metadata regarding the topology, may answer queries in regard to the specified topology.

Topology service using closure tables and metagraphs

Techniques for managing resources within a data center include using a portable device for interaction with technicians. The portable device has a web browser that the technician uses to navigate to an administrative web site from which a browser-based application is downloaded. The application is executed by the browser and maintains a browser-based data store that is asynchronously synchronized with a back-end data store when network communications are available.
