Difference Between Framework And Api

Linux Kernel supports many Hypervisor, such as the KVM, Xen, and VMware VMI. Each Hypervisor has its own unique block, receptacle, console and other equipment models, device-driven diversification of the characteristics and optimization of the various platforms are less common, the need to provide a common framework and standard interface to reduce the Hypervisor The difference between virtualized devices, thereby reducing the burden of driving development. Virtual ...

What is multi-core technology? Multi-core refers to the integration of two or more complete compute engines (kernels) in one processor. The development of multi-core technology stems from the understanding of engineers that simply increasing the speed of a single core chip generates too much heat and does not bring about performance improvements, as previously http://www.aliyun.com/zixun/aggregation/2578.html "> This is the case with the processor product. They realized that at that rate in the previous product, the heat generated by the processor would soon exceed the surface of the sun. Even if ...

Cloud computing initial fixed investment high, marginal input low, which leads to diminishing marginal cost, marginal income increment. In cloud computing, both infrastructure, platform and software require higher initial fixed inputs. Once built, however, it can be reused over and over again, and each value-added business, with a lower marginal input, can be launched without developing infrastructure, platforms and software from scratch. What is cloud computing? Now is not without answers, but too many answers. Now the answer to "What is cloud computing" is so much that people can't figure out what cloud computing is. ...

The theory of increasing the range of returns 30 years ago, as if it were specifically tailored for cloud computing.　　　　　　 Can just explain the special principles of cloud computing. What is cloud computing? Now is not no answer, but too many answers. Now the answer to "What is cloud computing" is so much that people can't figure out what cloud computing is. The reason is that people just inductive local phenomenon, just grasp the cloud computing this elephant a part of the cloud as a whole. Of course, comprehensive induction, than the local induction is not much better, it makes the cloud computing infinite complexity, trapped ...

Compared with other technology vendors, VMware is probably the most willing vendor in the world to help enterprise users migrate their existing infrastructure to a more agile and efficient virtualization server. In short, VMware is a technology giant that has been widely successful in the domain of enterprise virtualization servers. When it comes to cloud computing, however, VMware's dominance is less robust and, to say, not even established. Amazon is now a well-deserved overlord, and VMware alone in the OpenStack is not enough to belittlin the warlords. Openst ...

In January 2014, Aliyun opened up its ODPS service to open beta. In April 2014, all contestants of the Alibaba big data contest will commission and test the algorithm on the ODPS platform.

InfoQ Chinese Station recently conducted an interview with Xu Changliang, the technical leader of the ODPS platform, and exchanged such topics as the vision, technology implementation and implementation difficulties of ODPS. InfoQ: Let's talk about the current situation of ODPS. What can this product do? Xu Changliang: ODPS is officially in 2011 ...

As an important form of cloud computing, IaaS services have a wide range of open source and commercial cloud platform scenarios. This article is based on the use of open source IaaS cloud platform to develop public and private cloud management platform perspective, introduced and compared eucalyptus, Opennebula, Cloudstack and OpenStack, such as open source IaaS cloud platform. The characteristics of the successful cloud platform from AWS AWS is the most successful cloud computing platform, the most important feature of the system architecture is to open the data and function through the Web service interface.

The Big data field of the 2014, Apache Spark (hereinafter referred to as Spark) is undoubtedly the most attention. Spark, from the hand of the family of Berkeley Amplab, at present by the commercial company Databricks escort. Spark has become one of ASF's most active projects since March 2014, and has received extensive support in the industry-the spark 1.2 release in December 2014 contains more than 1000 contributor contributions from 172-bit TLP ...
