What this article shares with you is about the technologies that cloud computing server technicians need. The editor thinks it is very practical, so I share it with you. I hope you can learn something after reading this article. Let's take a look at it with the editor.

As a new IT infrastructure management method, cloud computing enables IT departments to manage massive resources as unified large resources, supporting a substantial increase in resources without significantly increasing maintenance and management. Cloud computing related technologies are as follows.

Distributed computing

The most typical distributed computing model based on cloud platform is the Map Reduce programming model. Map Reduce divides large tasks into many fine-grained subtasks, which are distributed on multiple computing nodes for scheduling and computing, so as to obtain the ability to deal with massive data on the cloud platform.

Virtualization technology

Virtualization can greatly improve the efficiency and availability of resources and applications in the organizational process. Virtualization separates physical resources from the resources eventually presented to users, which is actually an alternative process, creating multiple alternative resources (virtual resources) on physical resources with a unified and good architectural design. Alternative resources and physical resources have the same interfaces and functions.

Distributed and unstructured data storage

On a distributed file system. Typical distributed storage systems for storing massive structured data include Google's BigTable, open source HBase and so on. These systems can store unstructured data (such as web pages, etc.) as distributed, multidimensional and ordered graphs.

Automated deployment technology

One of the core ideas of cloud computing is to simplify tasks as much as possible through automation, so that users can quickly get the resources and capabilities they need through self-service. Deployment is very important in infrastructure management. Automated deployment can provide a simplified process. After the user makes an application, the automated deployment platform automatically completes the corresponding department according to scheduling and reservation.

Application scale expansion

CVM provides a huge pool of resources, and applications have different load cycles. Dynamic scaling of application resources according to load can significantly improve the effective utilization of resources, that is, dynamically expand resources at high load and release excess resources at low load. This is the problem solved by application scale expansion technology.

This technology takes the application as the basic unit, sets different cluster types for different application architectures, each cluster type has a specific expansion mode, and then automatically increases or decreases resources for the application cluster by monitoring the dynamic changes of the load.

Distributed system storage technology

Distributed storage uses the storage resources of multiple servers in the cloud environment to meet the storage needs that can not be met by a single server. Its characteristic is that storage resources can be represented abstractly and managed uniformly, and can ensure the security and reliability of data reading, writing and operation.

These are the technologies that cloud computing server technicians need, and the editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
