The reason for the emergence of cloud computing
There are two reasons for the emergence of cloud computing, both market and technology. Let's first look at the reasons for the market.
Cloud computing was officially born in the "post-Moore's Law" era. In this era, due to the limitations of the process, it is more and more difficult to improve the CPU integration. At the same time, the performance cannot be greatly improved by simply increasing the CPU integration.
The amount of data is expanding at a rate far exceeding Moore's Law, and the demand for computing performance is increasing. Only computational concentration can improve performance, while distance is the enemy of computation.
In addition, the supercomputing center in Grid mode also performs centralized computing, but due to the technical architecture, it requires unified and reliable hardware, the cost is relatively high, and it is difficult to expand. The computing needs of society come naturally.
Cloud computing is largely a business model. Many Internet companies need a so-called asset-light model, that is, these companies have a lot of computing business, but are reluctant to build their own data centers, because data centers are heavy assets and require relatively large investment and post-maintenance.
And assets like data centers lose value over time.In addition to market reasons, there are many technical reasons for the emergence and existence of cloud computing.
The emergence and popularity of a product must wait until the related technologies are relatively mature, and cloud computing is no exception. The emergence and existence of cloud computing is mainly due to the maturity of the following key technologies:
Virtual technology.
Distributed storage technologies, such as GFS, Ceph.
SDN switch based on X86 platform
Linux Server .
KV database.
It can be said that cloud computing cannot exist without these key technologies. It is worth noting that many core technologies are not produced in cloud technology, but have been quite mature before the emergence of cloud technology.
It is under the catalysis of these conditions that in 2006 AWS first opened cloud computing business services based on virtualization technology.
Summary: Cloud computing is an Internet business built on many key mature technologies to solve huge computing needs.
