Distributed technology gets rid of the limitation of physical equipment, improves storage scalability, can process massive data efficiently and quickly, and respond to user needs. In actual work applications, enterprises can use multiple storage servers to share the storage load, and use location servers to locate and store information. It not only improves the reliability, availability and access efficiency of the system, but is also easy to expand.
2. Virtualization . Virtualization technology is mainly applied to the infrastructure layer (IAAS) of IT services, including computer room infrastructure, computer networks, disk cabinets, server virtual machines (CPU, hard disk, network card), etc. Virtualization is a kind of virtualization operation that uses simulation technology in software to perform more and less, less and more virtualization operations on computer hardware, such as virtualizing a powerful server into multiple independent small servers, and then serving different users ; Or virtualize multiple servers into one powerful server to complete specific functions.
Virtualization technology is a common basic technology in cloud computing, a form of computing that uses virtual resources to provide services to users. The biggest benefit of virtualization is to enhance the elasticity and flexibility of the system, reduce costs, improve services, and increase resource utilization efficiency.
Three service models of cloud computing are involved here: IaaS , PaaS , and SaaS .
IaaS layer, infrastructure as a service, service content includes computer room infrastructure, computer network, disk cabinet, server/virtual machine
PaaS layer, platform as a service, service content includes basic layer and operating system, database, middleware and runtime library.
SaaS layer, software as a service, base layer + platform layer + application software service.
Cloud computing technicians are based on different service types to deploy, upgrade, migrate, secure, high-speed, stable expansion and automation of various hardware and software. The working objects are physical network, virtual network, physical machine, virtual machine, container, storage, database and application.
3. Programming technology . That's right, although cloud computing is for resource integration and server management and maintenance, it also requires learning programming. Cloud computing is a delivery system that supports multi-user, multi-task, and concurrent processing. Its realization method is to conveniently distribute powerful server computing resources to our end users through the network, while ensuring low cost and good user experience. During the delivery process, the distributed parallel programming model in cloud computing projects will be widely adopted. Scripting languages such as shell and Python are commonly used in cloud computing programming technology and can be used for the development of operation and maintenance tools. At the same time, the cloud platform expands the development boundary and can realize cross-platform development (perfect integration with big data and artificial intelligence development platforms).
After learning the programming content well, it is also helpful for career promotion. You can change from operation and maintenance to operation and maintenance development, or development.
4. Large-scale data management and storage . The main advantage of cloud computing is that it can efficiently and quickly store and process massive data resources, not only to ensure data storage and access, but also to be able to perform specific retrieval and analysis of massive data. And these technologies are based on distributed technology, which can achieve high-efficiency processing capabilities and distributed resource management capabilities.
In a multi-node concurrent execution environment, the state of each node needs to be synchronized, and when a single node fails, the system needs an effective mechanism to ensure that other nodes are not affected.
5. Cloud security . The security issue of cloud computing has been paid more and more attention by users. During the transmission process, problems such as data leakage and loss are very easy to occur, and it is also vulnerable to various network attacks. Including network security, server security, software security, and system security, the high security requirements of cloud computing bring traditional security technologies to a new stage, including technical fields such as firewalls, web penetration, and vulnerability attacks.
6. Cloud platform management . The cloud platform undertakes various cloud computing technologies and services, and users log in through the cloud platform account provided by the cloud service provider to carry out business management and maintenance work. The cloud platform needs to have the ability to efficiently allocate a large number of server resources, and the ability of various resources to work together; including technologies such as rapid deployment and opening of new services, rapid discovery and recovery of system failures, and reliable operation of large-scale systems through automated and intelligent means. content.
Second, what technical points do cloud computing need to learn and master?
