KubeCon+CloudNativeCon-the industry's biggest event was held in San Diego this year, attended by more than 12000 attendees and more than 100 cloud native suppliers. More and more enterprises begin to adopt K8S and container architecture to carry out digital transformation. We summarize the current challenges in the development of K8S and the five major trends of K8S in the future, which we share here.

K8S recognized that the complexity is high, how to reduce the complexity of deployment, how to increase the visibility and ease of operation of the system has become an important direction of development. In the current situation, it is difficult for users to know what is happening and who has access to the data. The complexity of the system makes many configurations error-prone. In addition, the security of encryption technology protects the communication security between container cluster and multi-cloud. And keep the system up-to-date through security updates including Kubernetes, underlying OS and software components in the container.

How to use database in container architecture through K8S has become an important trend. At present, the support of K8S for database function is not strong enough. The ability to store data in a state is mediocre. This makes it difficult for K8S to carry production systems and core application systems on a large scale.

How to provide a more effective and simple means to manage containers to deal with the key problems faced by users in similar traditional architectures, such as storage and data management, including migration, backup, encryption, disaster recovery, and so on, it has become an important prerequisite to determine whether enterprises can quickly adopt container and micro-service architecture to realize cloud native digitization of production system. Among the K8S users surveyed, 46% mentioned security issues, with network and storage ranking second and third, respectively.

Enterprises are increasingly adopting hybrid cloud / multi-cloud architecture, which has become an important reason for driving container technology. A large number of public cloud users are adopting a multi-vendor strategy, which has risen from 13% in 2016 to 27% in 2019. In addition, hybrid cloud usage increased from 24% to 32% over the same period of time. Running applications on multiple cloud platforms has become the main driving force for the use of container technology, bringing far more benefits than ever before, such as improved developer efficiency and support for micro-services.

K8S is gradually being applied to the production environment and core applications. Centralized management of multiple Kubernetes clusters, such as development, test, and production clusters, or multi-cloud settings for dynamic workload processing will become more common. According to a survey by Redmonk, a well-known software industry analyst, 71% of Fortune 100 companies use containers, and more than 50% of them use Kubernetes as a container orchestration platform. In addition, CNCF also pointed out that well-known international companies such as the New York Times, eBay, Uber, Goldman Sachs and Buffer have used Kubernetes in a large-scale production environment.
