In the past year, hybrid cloud and multi cloud have been a hot topic. More and more enterprises realize that choosing multiple clouds to provide services will not only reduce costs, but also stimulate cloud manufacturers to provide more innovative services. (source: IT168)

Although multi cloud management is the general trend and accepted by the majority of users in a new ecological form, the underlying infrastructure problem of cloud has not been fundamentally solved, and there are still challenges in how to migrate workload through more reasonable scheduling tools. For example, IBM mainly solves the underlying architecture problems through acquisition in 2019, but so far, we have not seen significant results. To solve the bottleneck problem of CI / CD continuous integration / continuous deployment should be the key problem to be solved by all enterprises led by IBM in 2020. Only by solving the problems of rapid deployment, scalability, integration and interoperability between public cloud and private cloud, can multi cloud target become possible.
Another challenge of multi cloud management is cloud visualization and monitoring. In order to ensure the stable operation of cloud workload, it is inevitable to establish a more powerful monitoring system. However, if we want to effectively monitor the multi cloud infrastructure, the complexity will be greatly increased. Therefore, in 2020, cloud computing manufacturers will focus on solving similar problems, which is the fundamental reason why Google cloud releases new open platform anthos.
On the whole, there are several key trends that enterprises should focus on if they want to do well in the cloud environment in 2020.

1. The faster the business grows, the more likely it is for the enterprise to withdraw its workload locally

In 2019, there is a particularly popular word called "cloud repatriation," which means that more and more enterprises are moving their selected applications from the cloud back to on premises or hosted data centers. In fact, cloud repatriation is only a "minority phenomenon", and most enterprises are moving their business to the cloud on a large scale. In 2020, with the enhancement of public cloud market capacity, more and more enterprises will follow the cloud native concept and reduce cost and increase efficiency through hybrid cloud.
As for why there is the phenomenon of cloud repatriation? In fact, it is not difficult to understand. For enterprises with limited budget and who want to try to go to the cloud, public cloud is a good choice. However, when enterprises go to the public cloud, with the increase of business volume, they will gradually find their own business limitations. How to reasonably allocate cloud resources becomes the next goal of the cloud. Therefore, the workload is transferred back to the local, which is only a choice of users in the cloud process, and does not mean that the cloud is on the decline. However, the future of public cloud is also going to a new stage. How to support users' mixed cloud needs at the data center level will be a key issue for public cloud service providers to overcome.

2. Public cloud security standards will be greatly improved

The U.S. Department of defense has decided to award a $10 billion cloud computing contract to Microsoft, which is a landmark event. This shows that more government agencies will put applications in the public cloud in the future, and the security and compliance standards of the public cloud will be greatly improved. Because the contract price is too tempting, there is fierce competition among different companies, such as AWS, Oracle and IBM.
Although this event occurred in the United States, it will produce a chain reaction to the cloud computing market all over the world, which will make the hybrid cloud construction environment form a higher standard, and there will be data separation requirements for public cloud and private cloud environment. It also allows enterprises to stay away from the cloud hosting mode and choose the appropriate solution according to their own business situation.

3. Improving the level of network automation through artificial intelligence / machine learning

At present, artificial intelligence and machine learning (AI / ml) have been put into practice from a fuzzy concept, and have realized large-scale commercial use. Almost all enterprises hope to rebuild their IT architecture and build new business models with the help of AI / ml technology. At the same time, the improvement of artificial intelligence technology also brings the enhancement of network capability. Many companies are also trying to cooperate with telecom companies to build stronger network framework.

4. Kubernetes has become an integral part of modern cloud infrastructure

Kubernetes has become the standard application of cloud operating system. Many enterprises are working hard in this direction, and combine with Devops concept, microservice construction and no server to realize management automation. I believe that this trend will continue to increase in 2020!
Of course, we do not rule out that kubernetes will raise doubts. Although kubernetes seems to have more technical strength, it is indeed very complicated to use kubernetes for management under specific circumstances, which requires more professional skills. Many users are worried that once kubernetes is used in large-scale production, there will be security problems and downtime, so it is particularly important to find a supplier who understands kubernetes.

5. 5g will make the era of "streaming media as a service" come true

In the past ten years, mobile games have developed rapidly. According to statistics, in 2018, the global game industry value reached nearly 138 billion US dollars, of which more than 70 billion US dollars came from mobile games.
By 2020, with the expansion of 5g, we will see that the development of mobile games will be further accelerated, because 5g provides strong connectivity, low latency and bandwidth capabilities, and needs to carry more graphics content. In other words, the "streaming as a service" model will flourish in the game field, and subscribers can access more sophisticated game programs with the touch of a button.
In fact, 5g really plays a role in the release of computing power. Due to the rapid development of GPU, cloud games have been rapidly popularized. With the rapid deployment of 5g network by large telecom operators, mobile games will gain more development space in 2020. This change will also stimulate the further development of new technologies, and more people will be interested in open source applications.
