In addition, Deltacloud also includes some ...

Both public cloud service users and private cloud users face the task of managing the upper limit of concurrent requests for servers. Because the infrastructure itself is a service, IT staff creates concurrent processing request caps, manages caps, and maintains load balancing and storage management through Control Panel and application interfaces. Different cloud vendors offer disparate application interfaces. 　　The lack of interface standards for cloud applications, how IT professionals can achieve effective control, align them with current services, and remain compatible with future cloud services. Many organizations have begun to test the development of a standardized application for cloud computing ...

Apache Cassandra is a highly performance, scalable, distributed NoSQL database with a flexible, simple partitioned row storage data model that can be used to deal with commercial servers and massive data storage across data centers without a single point of failure. It was originally developed by Avinash Lakshman (Amazon Dynamo developer) and Prashant Malik on Facebook to address their inbox-search problems, then officially open source in July 2008, and since then ...
