the white paper on Cloud Computing Development (2020) issued by the Chinese Academy of information and communications (hereinafter referred to as the Chinese Academy of communications and communications) shows that after more than ten years of development, The scale of China's cloud computing market has grown rapidly from the initial billion yuan to nearly 200billion yuan in 2020. The rapid development proves the success of cloud computing in technology and concept, and also shows that cloud computing is the only way for most enterprises to start digital transformation

the public cloud has relatively low resource prices, more flexible scalability, and complete platform and application service options, while the private cloud can provide better performance, lower latency, and reliability and security for key businesses. These are all factors that enterprises must consider when expanding their business. Therefore, it is natural for hybrid cloud to become popular

hybrid cloud has become the mainstream form of cloud

at the 2021 navigate navigator summit held in April, the Institute of cloud computing and big data of the Chinese Academy of communications and communications jointly prepared and released the blue skin report on hybrid cloud jointly with the Xinhua three group under Ziguang. The report not only makes a detailed summary of the current development of the domestic mixed cloud market, but also deeply analyzes the composition of the elements of the mixed cloud and the future development trend

the report points out that compared with the 82% deployment ratio of hybrid cloud in the global market, this figure is just over 50% in China. The reason for this difference is that, on the one hand, the deployment of domestic hybrid clouds started late, and on the other hand, there are still many barriers in traditional hybrid clouds in terms of multi cloud management, cloud collaboration, security, etc., resulting in less than expected cross cloud deployment of complex applications

in order to meet different needs, there are branches of public cloud and private cloud in cloud computing. Similarly, on the development path of hybrid cloud, isomorphism and heterogeneity have also become the two key directions of hybrid cloud development in the new era

homogeneous and heterogeneous in hybrid cloud

as the name suggests, homogeneous hybrid cloud means that public cloud, private cloud and edge cloud adopt the same technical architecture. This natural unity makes it easy for enterprises to obtain complete consistency in resources, services and security in all clouds and all business scenarios, so that businesses and applications can expand rapidly. At the same time, enterprises can also maximize management efficiency and reduce operation and maintenance costs

in contrast, heterogeneous hybrid cloud means that public cloud and private cloud adopt different architectures at the server, OS and other levels, but achieve unity at the PAAS and other management platforms. Thus, it can be targeted to build the infrastructure according to different scenarios and applications. The tensile properties of Jinan Shijin plastic and rubber are one of the most important and basic mechanical properties, so as to maintain openness and meet diversified needs at the same time

according to the different characteristics of the two hybrid clouds, the report also points out the scope of application of homogeneous hybrid clouds and heterogeneous hybrid clouds: the former is more suitable for small and medium-sized enterprises and new businesses that need frequent changes and reconfiguration, while the latter is more suitable for large enterprise groups and governments with complex businesses, high reliability requirements and compliance restrictions. At the same time, the report also points out that even if there is an essential difference at the architecture level, both homogeneous and heterogeneous hybrid clouds focus on the unified management and unified operation and maintenance of multi clouds

therefore, no matter what kind of hybrid cloud structure the user chooses, the solution provider should have both the product and technology background of public cloud and private cloud, and provide a variety of cloud delivery modes including multi cloud, public cloud, private cloud and edge cloud based on long-term government enterprise customer service experience

four key capabilities of hybrid cloud

starting from the characteristics of hybrid cloud, it is not difficult for us to find that in order to achieve unified management and efficient operation and maintenance, hybrid cloud solutions must have strong capabilities in the four dimensions of multi cloud management, cloud collaboration, security management and cloud native. These key capabilities will determine the deployment location, interaction mode and collaboration efficiency of user applications, and then have a huge impact on the business

1. Multi cloud management

multi cloud management of hybrid cloud is not simply compatible with openstack, VMware, kubernetes, rancher, etc. it is a waste of virtualization, but also needs to help users establish unified operation and maintenance management, service operation and security capabilities across multiple resource forms. At the same time, the hybrid cloud should also have many functions on the unified management portal, such as unified management of multi resource pools/multi tenants, permission allocation, metering and billing, platform approval, service directory maintenance, organization management and so on. Thus, users of hybrid cloud can ignore the complexity of technology and architecture and focus on service, operation and maintenance and business innovation

2. Cloud collaboration

public and private clouds together form a hybrid cloud. Therefore, users must also consider the data exchange and flow between applications in different locations, network environments and configurations in the process of business deployment and management. This means that the hybrid cloud not only needs to provide traditional VPN and dedicated line services, but also should actively use SDN or related technologies to provide cloud dedicated lines and cloud dedicated lines to ensure the end-to-end network connection of the hybrid cloud

3. Security management

the public cloud and the private cloud in the hybrid cloud have their own network boundaries. Therefore, users should not only pay attention to the network security within the boundaries, but also ensure the network reliability and data security between the boundaries. In terms of data security, hybrid cloud first needs to use various security encryption algorithms to avoid public transmission of plaintext data, so as to reduce data and economic losses caused by security events. Secondly, users of hybrid clouds also need to deploy unified and more consistent security policies on public and private clouds. Thus, users can more uniformly analyze and plan the impact of various security incidents and threats, and form a complete security system

4. Cloud native

cloud native requires the PAAS platform to unbind the functions and hardware to realize the modularization of functions. These modules can be loosely coupled to form a service platform that is easy to combine and expand, so that the upper application can easily call. In practical application, PAAS platform shall provide various capabilities and services in the form of API. At the application level, users can realize the hybrid cloud deployment of development tools and development processes in container and other lightweight ways, so as to realize the formation of Devops agile development system

practice brings true knowledge and insight into the future

in the blue report on hybrid cloud, some excellent practices in the industry are also shared: for example, in innovative projects such as Tianjin University and Wuqing District smart city, the homogeneous hybrid cloud has realized a high degree of collaboration in resources and applications in education, cities and other fields, significantly improving the work efficiency of users; In the cloud process of a large energy enterprise, the unified management and scheduling of resources across regions and resource pools are realized through heterogeneous hybrid cloud. The continuous implementation of many hybrid cloud projects has proved that the hybrid cloud solution has full feasibility and can meet the multi-dimensional needs of users

the report also points out that there are three major development trends in hybrid cloud, including computing power diversification, distributed deployment and cloud resource abstraction. In addition, industry leaders are continuing to carry out forward-looking technology exploration and product research and development in these fields

as one of the main means to realize digital transformation, hybrid cloud will continue to develop with the continuous deepening of digital transformation of government and enterprise users. This requires the public cloud and private cloud parts of the hybrid cloud to carry out continuous technology exploration, architecture exploration and scheme exploration on the premise of mutual collaboration, mutual promotion and mutual reference. With the deepening of the digital transformation process, the evolving hybrid cloud solution will help Baixing Baiye achieve a broader digital future
