Mining cloud computing Alibaba cloud

1. Don't dream of bitcoin any more. In this era of mining, especially renting servers, the rent you pay will far exceed the value of bitcoin you dig out.

2. Of course, if you don't believe it, you can search their official website on the Internet and have a look. I have done digital currency mortgage in their bank

3. Personal mining has no future

Alibaba cloud and Tencent cloud are both in use at present. This needs to be analyzed according to the specific procts of customers:

1. Alibaba cloud: the price of Alibaba cloud is on the high side of all cloud servers, which is also the reason why it is the earliest and largest in China. In terms of performance and security warning, alicloud's configuration is relatively stable, and the domain name resolution is updated relatively quickly. It is not suitable for novices, and has a certain learning cost, and the technology is too complex

2, Tencent cloud : on the whole, it feels comfortable to use, and there is no problem usually. If there is a problem, the work order response is relatively fast, and you can find a solution in the cloud document. Of course, if it's a student, there are all kinds of preferential machines for students. The operation is user-friendly, and it's fast and convenient to start. I feel it's especially suitable for students of science and engineering. It's very good to build personal websites or various technical demos

5. Because cloud computing can generally be divided into IAAs, PAAS and SaaS three different types of services, and different manufacturers provide different solutions, so far there is no unified technical architecture, which constitutes an obstacle for readers to understand the principles of cloud computing. For this reason, this paper constructs a cloud computing architecture for discussion by integrating the schemes of different manufacturers
cloud computing technology architecture is divided into four layers: physical resource layer, resource pool layer, management middleware layer and SOA construction layer. The physical resource layer includes computer, memory, network facilities, database and software
the resource pool layer is a kind of resource pool that makes a large number of resources of the same type isomorphic or nearly isomorphic, such as computing resource pool, data resource pool, etc. The construction of resource pool is more about the integration and management of physical resources, such as how to install 2000 servers in a standard container space, solve the problems of heat dissipation and fault node replacement, and rece energy consumption; The management middleware is responsible for the management of cloud computing resources and the scheling of many application tasks, so that resources can provide services for applications efficiently and safely
the SOA construction layer encapsulates cloud computing capabilities into standard web services, and integrates them into the SOA system for management and use, including service registration, search, access, and service workflow construction. The management middleware and resource pool layer are the most critical parts of cloud computing technology, and the function of SOA construction layer relies more on external facilities
the management middleware of cloud computing is responsible for resource management, task management, user management and security management. Resource management is responsible for the balanced use of cloud resource nodes, detecting node failures and trying to recover or shield them, and monitoring and statistics the utilization of resources
task management is responsible for the execution of tasks submitted by users or applications, including the deployment and management of user task image, task scheling, task execution, task lifecycle management, etc; User management is an essential part of cloud computing business model, including providing user interaction interface, managing and identifying user identity, creating the execution environment of user program, charging for user use, etc
security management ensures the overall security of cloud computing facilities, including identity authentication, access authorization, comprehensive protection and security audit
based on the above architecture, this paper takes IAAs cloud computing as an example to briefly describe the implementation mechanism of cloud computing
user interaction interface provides access interface to applications in the form of Web services to obtain user requirements. Service directory is the list of services that users can access. The system management mole is responsible for managing and allocating all available resources, and its core is load balancing. The configuration tool is responsible for preparing the task running environment on the assigned nodes. The monitoring and statistics mole is responsible for monitoring the running status of the node and completing the statistics of the user's usage of the node. The execution process is not complicated: the user interaction interface allows the user to select and invoke a service from the directory. After the request is passed to the system management mole, it will allocate appropriate resources to users, and then invoke the configuration tool to prepare the running environment for users. The above describes cloud computing technology.

6. In short: alicloud (alicloud Computing) is an online public relations platform created by Alibaba. Ali officially provides technical support, enterprises provide services to the public with the help of the platform, and the application system on the platform is developed and managed by the entrants themselves. Alibaba cloud platform can provide more convenience to people's life, involving all aspects. Many enterprises have settled in, and Alibaba cloud provides services to users.

7. Computing power cloud computing is an Internet-based computing method. In this way, shared software and hardware resources and information can be provided to computers and other devices on demand. It is mainly a mode of increasing, using and delivering Internet-based related services, It usually involves providing dynamic, scalable and often virtualized resources through the Internet. Cloud is a metaphor of network and Internet. In the past, cloud was often used to represent telecom network, and later it was also used to represent the abstraction of Internet and underlying infrastructure. In a narrow sense, cloud computing refers to the delivery and use mode of IT infrastructure, which means to obtain the required resources on demand and easy to expand through the network; Guangyi cloud computing refers to the mode of service delivery and use, which refers to obtaining the required services on demand and easy to expand through the network. This kind of service can be it and software, Internet related, but also other services. It means that computing can also be circulated through the Internet as a commodity
alicloud is committed to building the basic service platform of cloud computing, focusing on providing large-scale, low-cost cloud computing applications and services for small and medium-sized enterprises. Feitian is a cloud computing platform independently developed by Alibaba cloud. Cloud OS is a cloud intelligent mobile operating system integrating cloud data storage, cloud computing services and cloud operating system.

8. Alibaba cloud server can be used stably.

Because Alibaba cloud is essentially different from other clouds, but they are all realistic choices. Alibaba cloud, a cloud computing brand of Alibaba group, is the world's leading cloud computing technology and service provider. Founded in 2009, it has R & D centers and operation agencies in Hangzhou, Beijing, Silicon Valley and other places. In 2010, Alibaba cloud opened its technical service capabilities in the field of cloud computing. Through Alibaba cloud, users can remotely obtain massive computing, storage resources and big data processing capabilities through the Internet. As of June 2014, Alibaba cloud had more than 1.4 million customers, covering the Internet, mobile app, audio and video, games, e-commerce and other fields. According to IDC Research Report, Alibaba cloud is the largest public cloud computing service provider in China. Remote deployment system business based on the new generation of cloud platform has become the first choice of Internet companies and developers. Since 2013, the most risk sensitive financial institutions have started to go to the cloud. Alibaba cloud has built a financial cloud for banks, insurance companies and securities companies. With the security and stability of cloud computing constantly proved by practice, more and more government agencies, central enterprises and large private enterprises have begun to embrace cloud computing and big data. In December 2014, 75% of the remaining ticket query system of 12306 website was moved to alicloud computing platform to share the pressure brought by the Spring Festival traffic peak

both kinds of clouds are realistic choices. Two realistic choices of cloud. Alibaba has to stand at the commanding height of technology. Huawei and Tencent see the potential of cloud computing before they enter the market one after another. To tell you the truth, openstack is not suitable for the public cloud. It has some problems, such as confused versions, incomplete functions, and insufficient compatibility and coordination. However, it is the quickest and most direct choice to realize commercialization, build ecology, and meet the needs from the technical point of view. Starting from scratch, Huawei and Tencent can't afford the time and the market. Openstack is very difficult to use, but it's like a second-hand car. If you transform it, drive it first and serve your own strategy. There is a hard wound in the doctrine of taking. The cloud based on openstack lacks core technical support, is difficult to expand, has many versions, has miscellaneous branches, poor stability, and has many faults. It is difficult to migrate and upgrade across vendors. The software moles come from many companies and lack unified planning and consistency. Many projects have become & lt; It's a rotten end;. Cisco and HP also abandoned openstack and withdrew from public cloud or independent research and development. While Huawei cloud and Tencent cloud are still building public cloud based on openstack, there are great challenges and opportunities in the future
