Abstract:
A system and method is provided for generating and using purchase strategies based on the price, performance, and/or other information related to cloud services to optimize the selection of such services. The purchase strategies may comprehensively describe various cloud services in real-time so that customers may purchase cloud services using up-to-date, real-time information. The purchase strategies may, for example, describe pricing, performance, availability, and/or other attributes of various cloud services. A purchase agent may use the purchase strategies, one or more purchase rules, and/or other information to generate a purchase specification that specifies one or more cloud service instances that should be purchased. The purchase agent may leverage unique properties of spot instances to make favorable purchase decisions. For example, the system may determine bid prices that should be made to obtain certain spot instances.
Abstract:
Approaches for providing a secure computational environment are disclosed. In certain implementations, a secure computational environment may be provided by: limiting exploitable or potentially exploitable sub-components in software components; replacing software components with corresponding known-good software components without regard to whether the software components have been compromised or potentially compromised; combining different information to be transmitted into different slices of a data packet and/or encrypting the slices using different cryptographic schemes; processing a data packet having data slices associated with different information that are encrypted using different cryptographic schemes; securing information using data packets having headers that start at different positions within a data packet with respect to other data packets; processing data packets having headers that start at different positions within a data packet with respect to other data packets; or utilizing other approaches.
Abstract:
A system and method for providing and executing a domain- specific programming language for cloud services infrastructure is provided. The system may be used to integrate references to external entities, such as cloud service compute instances, directly into a domain- specific programming language, allowing developers to easily integrate cloud services directly using the domain- specific programming language. Using a domain- specific programming language, references to external entities (not in memory) as variables may be used. Using the domain-specific programming language described herein, lexical scoping may be mapped onto collections of entities that aren't a native part of the language. In order to facilitate these and other benefits, the system may maintain state information of all references and shared variables across program boundaries. The system may make the state information accessible via a state information service that understands the language features of the domain- specific programming language.
