From traditional IT to public cloud computing

Over the years, cloud computing has grown very fast, and cloud computing has quickly become the IT infrastructure of choice for users. According to reports, in 2015, more than 1 million customers have deployed their IT systems to Alibaba Cloud, including application systems and databases. Alibaba Cloud needs to help so many customers manage such a large number of servers distributed in different regions of the world. It is understood that Alibaba Cloud The number of operation and maintenance teams is also very small, and only a few need to work as a tool for research and development. The operation and maintenance of ECS, RDS, SLB, OSS and other products are the same. While we are lamenting the highly automated operation and maintenance capabilities of Facebook and Alibaba Cloud, not every company has the same technology and operation and maintenance capabilities. Can this capability be replicated to corporate customers?

Alibaba Cloud, Amazon AWS, Tencent Cloud, etc. are in line with these trends, turning their technical capabilities into cloud computing platforms and opening them through services. Users can purchase and enjoy the technical capabilities behind cloud computing at any time. When asked how to choose a cloud service provider, the key point lies in the comprehensive capabilities behind cloud service providers.

Traditional IT processes take at least 2 months from the selection of IDC, procurement server equipment to installation and deployment. After the application goes online, a professional operation and maintenance engineer team is needed to ensure the good operation of the system and the high availability of the database. This is actually a huge engineering and manpower investment.

The emergence of cloud computing has made all this simple. Cloud computing has become a public computing service that can be purchased at any time. The core features include out-of-the-box, low threshold, high availability, free operation and maintenance. In the process of using cloud computing services, users no longer need to care about the underlying hardware such as IDC, server, network, storage, etc., and do not need to care about the complete set of operation and maintenance software such as installation, configuration, monitoring, and daily inspection of the operating system. Deployment, without considering the basic disaster recovery, backup, data loss, hardware failure, etc., these cumbersome IT infrastructure are all handed over to professional cloud service providers to solve.

Cloud computing is rapidly driving the IT division of labor more detailed, more professional, companies will be more focused on business-level logic design and code development, no need to invest a lot of energy in the cumbersome IT infrastructure and operation; IT infrastructure soft The hardware facilities will be provided by cloud service providers such as Alibaba Cloud, Amazon AWS, Tencent Cloud Q, Ucloud, Qingyun, etc.; application operation and maintenance, database, big data technology can be entrusted to professional cloud technology service companies, um, such as our kangaroo cloud (http://www.dtstack.com)

It seems that the benefits of the cloud are very many, how come?

• If it is a startup, you can do research and development and deployment directly on the public cloud;

• If the IT scale of the enterprise is relatively small, consider moving directly to the public cloud at one time;

• If the enterprise itself already has a large number of traditional IT hardware facilities, it is not realistic to put all the business on the public cloud in the short term, which requires a long-term verification process. First move the non-core system to verify and accumulate experience on the cloud, and gradually transition to the cloud on the core system. For this kind of scenario, the hybrid cloud architecture will be a good transition path for the cloud. Through the hybrid cloud architecture, the enterprise regards the public cloud computing as an extension of the organic room. It can be understood that the public cloud is another computer room of the enterprise, and can be used at any time. The service is switched to the public cloud, and the public cloud can also be used to make the disaster recovery equipment room, and the mutual disaster recovery under the cloud cloud. Similar to the well-known Weibo, 12306, etc., the similar architecture is adopted (http://geek.csdn .net/news/detail/64470).

Kangaroo Cloud can provide a complete cloud solution that can help all types of enterprises use cloud computing as an infrastructure.
