Extensible change control management for development and deployment of applications is described. A change control manager may register plugin components, including requester, approver and performer components, to process changes to a resource of a resource type, where registering is performed responsive to request(s) received via programmatic interface(s). Upon receiving a change request from the requester component, the change control manager may send the change request to the approver component to approve the change request and, responsive to notification of approval from the approver component, the change control manager may then send the change request to the performer component to implement the requested change. The change control manager and the various components each send and/or receive change requests encoded in a standardized schema for the resource type, the standardized schema independent of the implementation of the resource and the means of implementing changes to the resource by the performer component.

Extensible change control management

Online retailers may operate a network of computing systems in order to provide an electronic marketplace to customers. The network of computing systems may be responsible for maintaining and providing different data to the customers of the online retailer. When a customer transmits a request to the online retailer the request may be divided into a set of tasks that may be executed in parallel by the computing systems. The data generated by executing the various tasks may be cached for various periods of time. Furthermore, log information may be generated based at least in part on execution of the various tasks. The logs may record data on initial access along with an identifier associated with the cached data. For subsequent tasks requiring cached data the log may include only the identifier associated with the cached data.

Incremental business event recording

Methods and systems for avoiding or deferring data copies are disclosed. Using a virtual machine, it is determined whether a set of program code comprises references to a data object after an operation to generate a copy of the data object. If not, a set of optimized program code is generated in which the operation to copy the data object is replaced with an operation to update a reference. Using the virtual machine, it is determined whether the set of program code comprises an operation to generate a copy of a buffer object. If so, a set of further optimized program code is generated, comprising an allocation of one or more memory pages to store the buffer object with a copy-on-write parameter instead of the operation to generate the copy of the buffer object.

Avoiding or deferring data copies

Disclosed are various embodiments for hierarchical modeling of network sites. A page model from a hierarchy of page models is provided in at least one computing device. The page model includes a plurality of features. Each one of the features is assigned to a respective network page region. The features include at least one original feature and at least one inheritable feature from a parent page model. A network page is generated in the at least one computing device corresponding to the page model. Each one of the features of the page model is encoded for rendering within the respective network page region.

Hierarchical modeling for network sites

Methods, systems, and computer-readable media for proactive seeding of build artifacts are disclosed. A dependency graph is determined that represents dependency relationships among a plurality of build artifacts. Using the dependency graph, a repository manager determines a first set of one or more build artifacts. The first set of build artifacts are stored in one or more repositories. The first set of build artifacts are sent from a repository manager to a client over a network. The first set of build artifacts are used by the client in generating a software build.

Proactive seeding of build Artifacts

Optimization preferences are defined for optimizing execution of a distributed application. Candidate sets of application parameter values may be tested in test execution environments. Measures of performance for metrics of interest are determined based upon the execution of the distributed application using the candidate sets of application parameter values. Utility curves may be utilized to compute measures of effectiveness for metrics of interest. A multi-attribute rollup operation may utilize the computed measures of effectiveness and weights to compute a grand measure of merit (MOM) for the candidate sets of application parameter values. An optimized set of application parameter values may then be selected based upon the computed grand MOMs. The optimized set of application parameter values may be deployed to a production execution environment executing the distributed application. Production safe application parameters might also be identified and utilized to optimize execution of the distributed application in a production execution environment.

Optimization of application parameters

Techniques are described for delivering one or more first resources of a page using a first security level, and delivering one or more second resources of a page using a second, different security level. A page is generated to include elements identifying resources to be presented in the page, and the elements may include security level identifiers indicating a security level to be employed in communicating the corresponding resource. Each security level may be associated with a set of security measures that ensure the integrity or confidentiality of the resource while it is communicated. The use of multiple security levels to communicate multiple resources may provide appropriate security for each resource, reducing latency and overhead in page generation, communication, and rendering.

Content delivery employing multiple security levels

A computing device can obtain a session key for encrypting data that is communicated between a client device and the computing device. The computing device can receive, from the client device, an encrypted request for data. The encrypted request can be encrypted by the client device using the session key. The data requested can be stored on a second computing device. The computing device can send, to the second computing device, a copy of the session key and the encrypted request for data. The second computing device can decrypt the data using the session key and can also encrypt data responsive to the request using the session key.

Secured communication in network environments

Disclosed are various embodiments involving a container contract for data dependencies using representational state transfer (REST). A data resource is obtained by way of REST after determining that an application component has a dependency on the data resource. The application component is invoked to process the data resource. The data resource may be sent to the server by way of REST to effect a modification to the data resource in the server.

Container contract for data dependencies

A system for transmitting data over a network may include data processed according to a data-redundancy encoding technique such as erasure coding to be transmitted via an unreliable, connectionless transmission protocol, for example user datagram protocol ('UDP'). A transmitting manager may receive a request from an application to transmit data. The transmission manager may select encoding parameters and encode data to be transferred using a data-redundancy encoding technique. The transmission manager may initiate transmission of the encoded data and payload header data may via a network, for example via a network communication stream or protocol stack. A reconstruction manager associated with the receiving node may reconstruct the original data using the received erasure coding data and payload header data. In some embodiments, the receiving node may transmit telemetry data to the erasure coding algorithm. The erasure coding algorithm may use received telemetry data to adjust parameters of the erasure coding algorithm for future erasure coding and transmission operations. In some systems, telemetry data may include a request to retransmit all or a portion of the erasure coded data.

Transfer of data-redundancy encoded data via unreliable, connectionless protocol

A system for conducting a code review of program source code including translation of content in the program source code may include a source control system. The system may also include a resource file translator to facilitate translation of the content from a first language into second languages. Upon receipt of a code review request, the source control system may notify a workflow manager that the resource files contain the content for translation, and the workflow manager may notify a resource file translator that the program source code contains the content for translation. The resource file translator may cause translation of the resource files into translated resource files. The source control system may receive program source code under review from a code reviewer interface, and the resource file translator may update the program source code under review with the translated resource files.

Code review with automated translation

A content management system (CMS) and a translation management system (TMS) can utilize content dimensions for content items to manage and translate the content items between languages. Machine and human translations of complex dynamic content can also be improved by pre-rendering the content to remove localization-related syntax prior to machine or human translation. Content items can also be scored as to their suitability for localization prior to translation, and translation can be skipped for content items that do not have a sufficiently high score. Semantic and natural language processing (NLP) techniques can also be utilized for content categorization and routing. Translations of content items can also be continuously refined and higher quality re-translated content can be provided in an automated fashion.

Continuous translation refinement with automated delivery of re-translated content

Disclosed are various embodiments for generating network pages for customers that include customer-generated page portions. A request for a network page is obtained from a client. The network page is associated with a network site hosted on behalf of a first party by a second party. A portion of the network page is obtained from a service operated by the party in response to the request. The network page, which includes the portion, is generated in response to the request. The generated network page is sent to the client in response to the request.

Generating network pages using customer-generated network page portions

Described is a dynamic web platform configured to provide content rendered with one or more rendering systems. The rendering systems and the modules making up the rendering modules may interact with one another by way of declarative data. Administrators may configure the platform using the declarative data. The declarative data may express operational parameters, business rules, and so forth and may be modified while the platform is operating. The modules in the rendering system may be loosely bound, allowing for concurrent operations, dynamic changes to what content is to be rendered, and so forth.
