Disaster recovery in cloud computing is a relatively new concept, and like many technology trends, there is a lot of hype and wrong information. In the "Storage" magazine article from Jacob Gsoedl, one can understand the top disaster recovery issues of cloud computing, such as security and data recovery, and whether disaster recovery in the cloud is a good choice for the organization.
At present, cloud computing is already a very mature technology and application. The definition given by the National Institute of Standards and Technology (NIST) to cloud computing is: Cloud computing is a convenient and on-demand use of shared pools.
Cloud computing has been hot in recent times, and the topic of it is overwhelming. And the progress of cloud computing has also risen from the previous conceptual speculation to the product stage, and the discussion about the impact of cloud computing on various industries has become increasingly deep.
Over the years, cloud computing has grown very fast, and cloud computing has quickly become the IT infrastructure of choice for users. According to reports, in 2015, more than 1 million customers have deployed their IT systems to Alibaba Cloud, including application systems and databases.
Cloud computing is the most advanced and hot information processing technology in the world. It depends on the network. If it was 20 years ago, no one would consider cloud computing at all, because the network was too slow, and it was knocked back every time.
The rapid growth of life science research data has led the industry to turn its attention to cloud computing applications, especially in the field of genetic research.
As early as 2010 and 2011, the prediction of the glorious future of cloud computing became the headline news. Analysts predict that the arrival of cloud computing is the best technological development since the invention of the computer.
Dresner Consulting Services recently released its seventh annual report titled "2018 Cloud Computing and Business Intelligence Market Research." With a total of 102 pages, the report is the most in-depth report in the field of rapidly growing cloud computing business intelligence.
At present, the concept of cloud computing is in full swing in the industry. The newspaper articles on cloud computing are also emerging one after another. At this year's China Cloud Computing Conference, many leaders, experts and scholars also called for and called for the establishment of cloud computing standards.
Cloud computing is a resource delivery model that uses the resources needed to get applications through the network. Cloud computing packages computing devices, software, and services, changing the way people access, process, and store information.
Dr. Wang Jian, president of Alibaba Cloud, said cloud computing is not an area where all enterprises have the ability to get involved. Technology is important, but practical experience is more important, and operation is the core of cloud computing. This has opened up our re-understanding of cloud computing.
Cloud computing has just developed and it has developed rapidly. The competition life cycle of many traditional IDC industries is shortening. Internet unicorns with cloud computing as their core competitiveness are appearing faster and faster.
In recent years, cloud computing, as one of the most promising vocabulary in the IT industry, has received attention from various industries.
In the past two years, the overall penetration rate of cloud computing has been continuously improved, and the turning point of the industry has arrived.
The development of the economy has led to the emergence of software and computing power service infrastructure, commonly known as cloud services or cloud computing.
At the recent Yunqi Conference, Alibaba Group senior vice president and president of Alibaba Hu Xiaoming announced that IoT (Internet of Things) officially became the main strategy of Alibaba after e-commerce, finance, logistics and cloud computing, and in order to do a good job of IoT Alibaba Cloud will invest in the emerging technology field of “edge computing” in 2018.

First, eigenvalue decomposition 1, matrix multiplication before introducing the geometrical meaning of eigenvalue and eigenvector, the geometric meaning of matrix multiplication is introduced. Matrix multiplication corresponds to a transformation, a new vector that transforms any vector into another direction or length. In this process, the original vector mainly occurs in rotation and expansion of the change. If the matrix only has a scaling transformation for some vectors and does not produce a rotational effect, then these vectors are called the eigenvector of the matrix, and the scale of the scaling is the characteristic value. For example:, its corresponding linear transformation is the following form: Because the matrix M is symmetrical ...
Overview The key information maintained by the control plane is the network state. The control plane must aggregate this information and make it available to the application. In addition, in order to maintain scalability and component reuse, applications should be exempt from protocol details, even though network state information is obtained through a specific protocol. The Onos topology of the protocol is implemented by two complementary mechanisms: Network Discovery and configuration. The former uses the network protocol to let Onos identify the location and/or performance of the network elements, and take the initiative to carry out the relevant collection work when the function is enabled. The latter allows applications and operations ...
