Abstract: Domain Name System (DNS) requests can be routed to either a private DNS server or a public DNS server based on a determination made by a DNS classifier. The private DNS server allows customers to use custom DNS names for internal resources without exposing the names or IP addresses to the public Internet.

Abstract: Systems and methods are described to enable health checking of computing devices within a virtual private cloud (VPC) networking environment, without requiring that the devices be accessible via a public network address. An endpoint is placed within the VPC, which enables interaction with an external health checking system via a substrate network. The endpoint handles communications between the heath checking system and the VPC, and can modify data originating from the health checking system such that it appears to originate from the endpoint. From the viewpoint of the VPC, the endpoint itself may appear to be conducting health checking. Thus, external health checking can be used on a VPC without compromising the security of the VPC by requiring that a portion of the VPC be externally addressable.

Abstract: Systems and methods are described to enable adaptive handling of domain resolution requests originating from a virtual private cloud (VPC) networking environment. An administrator of the VPC can provide a set of rules specific to the VPC that designates how requests for a domain name should be handled. The rules may specify, for example, that a request for a given domain name should be routed to a particular domain name server, which may include a private domain name server, should be dropped, or should be routed according to a default behavior (e.g., a public domain name system). Resolution requests originating in the VPC can be associated with a VPC identifier. When an adaptive resolution system receives the request, it can retrieve rules associated with the VPC identifier, and apply the rules to determine further routing for the request.

Abstract: A service is described that makes it easy and cost-effective to configure network traffic flowing to multiple endpoints. Enterprises and developers can easily manage the way that end-users are routed to applications running in different geographic regions. Customers can route traffic based on multiple criteria in a customer policy. Customers can manage large-scale, multi-region applications, increase application availability, and minimize latency to end-users. The service can consider the state of end-users, such as their geography, their network, and their latency to different geographic regions. The service can also consider the state of the customer's applications, such as the load on the application, the application's health, the cost of using that application (e.g., resource costs), resource states (e.g., disk throughput), resource location, customer-provided endpoint cost parameters, etc.

Abstract: Systems, methods, and computer storage media having computer-executable instructions embodied thereon that utilize images to generate identifiers of entities and to determine various relationships between entities and web pages are described. A collection of class images that represent various people and non-people entities deemed relevant for tracking user behavior is generated. Given a class image that represents an entity, an image identifier comprising unique feature vectors for that class image is generated. Given an arbitrary web page, all the images embedded on the web page are analyzed. Each embedded image is compared to the image identifiers of the collection of class images to determine whether or not any entities of interest appear in the embedded images of the web page. If relevant entities do appear on the web page, various associations can be made between the entities found on the page, and between the uniform resource locator (URL) of the web page where the entities appear.

Abstract: Randomized auctions with priority option may be applied in scenarios where a small number of bidders value an item much higher than other bidders. In an auction of an advertising impression, an advertising platform may compute a priority price to be paid by an advertiser who wins a priority auction for the impression. The advertising platform may collect bids from multiple advertisers, and may determine, based on the bids or on election indications from the advertisers, whether to enter any advertisers into the priority auction. In the priority auction, the impression may be allocated to the advertiser with the highest bid, who may be charged at least the priority price. If no advertisers enter the priority auction, the impression may be allocated randomly between the advertisers with the top d bids, and the advertiser winning the randomized secondary auction may be charged a payment amount equal to the (d+1)-th bid.

Abstract: A user's online activity is tracked and offers associated with online advertisements presented to the user are identified. Information regarding these offers are provided to a payment service, which associates the information with an account for the user. When the user performs an activity using a payment card or other payment mechanism, the payment service may identify the activity as corresponding with an offer. Information regarding the completion of the activity for the offer may then be associated with information regarding the user's online activity. Additionally, a rebate and/or incentive may be provided to the user based on completion of the activity.

Abstract: Systems, methods, computer-readable media, and graphical user interfaces for applying image-based contextual advertisements to images are provided. An image analyzing module and advertisement analyzing module analyze images and advertisements to identify image attributes and advertisement attributes. Upon identifying image attributes and advertisement attributes, advertisements deemed contextually relevant to an image are determined. In some embodiments, the contextually relevant advertisements are ranked. Thereafter, one or more contextually relevant advertisements are associated with the image. The one or more contextually relevant advertisements are presented based on preferences and/or features.

Abstract: Systems and methods are provided for adding an advertisement to a web page by associating advertisements with one or more visual objects e.g., text and/or pictures. Embodiments of the present invention include a method for selecting visual objects and associating the visual object with an advertisement after the web page has been displayed to the user. The visual object may be selected in part based on the user's interactions with the web page. An additional embodiment of the present invention displays the associated advertisement after a user clicks on or hovers over the selected visual object.
