Computer hardware can actually be more easily divided into CPU + memory +io devices. The three of them are through a bus to exchange data, and you know in the three CPU speed of the fastest, memory second, IO device third, to make the three coordination of communication requires a certain control. 2. our CPU has its own local bus, the same memory, the local bus through the motherboard of the South Bridge chip link together to communicate. North Bridge generally connected to high-speed bus (con

In addition to Microsoft. net technology, programmers can also use other non-Microsoft technologies to develop worker ro applications. 3. VM Role: This is a good understanding. It is a Windows Server 2008 R2 virtual machine. You can log on to it using a tool like remote desktop, just like a local co

1. All things in the world are objects A software engineering major student is blocked from the university campus and asked him what is object-oriented. He will tell you that everything in the world is an object. The world is so big that everything is more than anything else. Go to the stars of the universe, and go to the bacterial virus. All are objects. The girl is still pale and fragrant. The boy was so happy with his close eyes. Thi

Cloud computing has become the conventional form of enterprise IT construction, and virtualization widely adopted and deployed in cloud computing has almost become a basic technical model. The extensive deployment of server virtualization technology greatly increases the computing density of the data center. Moreover, because the virtual machine itself is not sub

Concept of cloud computing Cloud computing is a commercial computing model that distributes computing tasks in a resource pool composed of a large number of computers, allowing users to obtain computing power, storage space, and information services as needed. The core concept of cloud is resource pool. Why is it cloud

As a process automation role in the system center, it acts as a process-based role in the private cloud architecture, corresponding to the manual process and business order in the traditional IT architecture.

Kubernetes itself no matter the network, need to through the plug-in, Network and SDN who to manage? The kubernetes itself, regardless of the storage, needs to be done via plug-ins, and most of the storage options are done via Ceph. However, if you want to make a public cloud, at

Early, the call between services we can use RESTAPI to communicate, but to the late, after more services, but also through RESTAPI access to other services, because RESTAPI use Ip+port to access, the number of services to go up, The way code is embedded in an address or configuration file can cause administrative changes.
