In his last investigation, the Cloud Native Computing Foundation (CNCF) found that in 2019, the vast majority of professionals interviewed were using containers. This represents an increase of about 15% (73%, a year earlier) compared to the previous year. Main winner: Kubernetes. Explanations of this success.
The use of containers is becoming more and more popular. 56% of organizations surveyed for the 2020 edition of Red Hat’s The State of Enterprise Open Source report said they expected container usage to increase in the next 12 months.
To simplify their deployment and management on public or private clouds, companies rely on an orchestrator. Essential, because according to a CNCF study, the percentage of companies using 250 or more containers in production has increased by 28%. However, the percentage of businesses using fewer than 50 containers has dropped significantly (down 43%).
In most cases, organizations rely on Kubernetes, even if they don’t neglect competitors. Here are some significant statistics:
Kubernetes is not the only option for container orchestration, but it has clearly become an unavoidable choice: more than three out of four companies listed in the CNCF report said they use Kubernetes in one form or another.
By 2022, Gartner estimates that 75% of organizations will use “containerized” applications in production. But “organizations often underestimate the effort required to run containers in production,” according to analysts at the firm.
And remember that companies must first ask themselves if they have the necessary skills before adopting new technologies. This involves setting up the right DevOps team and examining how Kubernetes integrates with the rest of the infrastructure.
About seven in ten companies have reported a bad configuration detected in their Kubernetes environment. The more the use of Kubernetes increases, the more the general interest in the security of the platform increases.
However, a recent StackRox report found that a familiar threat is by far the most common cause of a Kubernetes incident. About seven in ten companies report detecting a misconfiguration in their Kubernetes environment, making it by far the most common type of vulnerability.
“The irony is that companies are moving to containers to speed up development, but they’re slowing down the delivery of apps for security reasons,” says StackRox.
A large majority of respondents to the StackRox study admitted to having experienced a security incident in the past 12 months. In many cases, the cause was an incorrect configuration. “These data highlight how difficult it is to keep containers safe,” says StackRox.
This is the number of Kubernetes operators available on OperatorHub.io. Creating an operator amounts to extending the functioning of Kubernetes using specific “Controllers” and “Custom Resource Definitions” to manage applications “natively”.
This is the number of certified Kubernetes service providers, according to the CNCF. It is a “prequalified group of controlled service providers with significant experience in assisting businesses to successfully adopt Kubernetes”. This figure corresponds to an increase of almost 50% compared to June 2019, when the program had reached the bar of 100 providers, less than two years after its initial launch.
