What are the advantages of cloud computing? How to learn cloud computing quickly and systematically? In recent years, cloud computing has developed rapidly. at the same time, with the deepening of big data, artificial intelligence and other research, cloud computing as its important technology and support, there will still be a huge space for development in the future. Let's take a look at it.

Cloud computing is a pay-per-use model, which provides available, convenient and on-demand network access for configurable computing resource pools (including networks, servers, storage, applications, services and other resources). There are three kinds of cloud computing, one is private cloud, the other is public cloud, and some people connect private cloud with public cloud as hybrid cloud.

Technical advantages of cloud computing:

Automation: systems can be reused to build and deploy by taking full advantage of a programmable (API-driven) infrastructure.

Automatic expansion: applications can be extended bidirectionally according to requirements without any human intervention.

Proactive expansion: based on demand expectations and reasonable planning of traffic patterns, applications can be expanded in both directions so as to maintain low-cost operation.

More effective development cycle: the development and test environment can be easily cloned to the production system, and the environment at different stages can be easily extended to the production system.

Improved testability: no hardware exhaustion testing is required.

Disaster recovery and business continuity: cloud services improve low-cost options for maintaining a range of DR servers and data storage.

Traffic overflow to the cloud environment: with a few clicks and an effective load balancing policy, you can create a complete anti-overflow application that routes excess access traffic to the cloud environment.

Business advantages of cloud computing:

Up-front infrastructure investment is almost zero. With a public cloud environment, there is almost no fixed cost or startup cost.

Real-time infrastructure. By adaptively deploying applications in the cloud, you don't have to worry about whether to purchase large systems in advance, which increases flexibility and reduces risks and operating costs.

More efficient use of resources. In a cloud environment, we can manage resources more efficiently and effectively release resources on demand based on the number of requests from the application.

Calculate the cost according to the use. With instrumental pricing, you can pay for infrastructure that is already used without paying for infrastructure that is allocated but not used.

Shorten the time to market. A resilient infrastructure provides the ability to take advantage of the cost-effectiveness of parallelization to shorten time to market.

Cloud computing has a huge talent gap in China, and the salary of employees is good. What is more worth mentioning is that cloud computing is the development trend of the Internet in the future, so if you learn cloud computing technology well, it will mean high salary and huge profits in the future. If you want to learn cloud computing quickly and systematically, you can choose a professional way of learning.
