State of Kubernetes: Report Roundup

According to recent surveys and reports on the industry, Kubernetes and containers are more popular than ever.  Containers and serverless functions are being mainstream and ubiquitous – with a more than 300% increase in container production usage in the past 5 years. This trend is especially true for large organizations, which are often using managed platforms and services.

Despite a drop in interest during 2020, Google Trends shows growth in search interest for Kubernetes since the beginning of 2021. Search growth is likely to continue over the next few years as the technology further expands and with no clear competitors.

In this blog post, we’ll take a look at a variety of surveys and data that collectively describe the Kubernetes landscape. Some of the consistent trends we’re seeing in the meta-analysis include:

1. Growing usage of Kubernetes, containers, and serverless technologies both in number of organizations and within organizations
2. Security and compliance are some of the top concerns for organizations using these technologies
3. Large organizations are the cohort leading the drive towards ubiquitous adoption
4. A heightened need for mature processes around Kubernetes monitoring, Kubernetes logging, & Kubernetes incident response

Cloud Native Computing Foundation (CNCF) Annual Survey

CNCF has conducted an annual survey of the cloud native community since 2016 to gauge adoption and trends within the industry. The most recent survey report, released in February 2022, was the largest yet with more than 3,800 participants from six continents are across a wide range of industries. This iteration of the survey was divided into two parts: (1) Kubernetes and Containers; (2) Cloud Native Technologies.

Key survey findings include:

• A record high of 96% of organizations are either using or evaluating Kubernetes – a major increase from 83% in 2020 and 78% in 2019.
• 93% of organizations are using or plan to use containers in production (up slightly from 92% in the prior year’s survey).
• More than 5.6 million developers are thought to be using Kubernetes today.

One of the more interesting trends found in the report is the increasing usage of Kubernetes within large enterprises. Survey participants from large organizations (defined as more than 5k full-time employees) were far more likely to use Kubernetes in production than those working in smaller organizations.

Among those who participated in the first part of the survey, the majority of respondents (79%) rely on Hosted platforms like Amazon Elastic Container Service for Kubernetes (ECS), Azure Kubernetes Service, and Azure (AKS) Engine. Nearly 40% of those who took the second part of the survey indicated they rely on serverless technology like AWS Lambda and Google Cloud Functions.

Based on prior year schedules, the next CNCF will likely open in late Summer or Fall of 2022, with a report released in early 2023. You can participate in the community and contribute data to the project. Learn more by visiting https://www.cncf.io/.

VMWare Tanzu’s State of Kubernetes Survey

In addition to the annual CNCF report, another annual report was published in April 2022 by VMWare Tanzu. This survey included more than 750 respondents from organizations with more than 1k employees, including more than 200 respondents from enterprises with more than 5k full time employees.  

Key survey findings include:

• Organizations are deploying more clusters, especially focused on software development and cloud adoption use cases.
• 65% of respondents run Kubernetes in multiple locations – from the edge, to public cloud, to on-premises – demonstrating the need for a multi-cloud strategy.
• Security and compliance are major concerns, particularly for multi-cluster and multi-team organizations.
• Consistent with the CNCF’s report, managed Kubernetes services are increasingly important for most organizations.

Nearly half of those surveyed expect their total number of Kubernetes clusters to expand by 50% in the next year.

Red Hat’s State of Kubernetes Security Survey

Released in May 2022, the State of Kubernetes Security report from Red Hat (and previously published by StackRox) has valuable insight into how organizations are dealing with some of the biggest security challenges. While a smaller total number of respondents than the other two surveys in this analysis, this report includes respondents from all sizes of organization and industries. Roles of the survey participants included: Security, Compliance/Risk, Operations, and Product Development/Engineering.

Key findings from this report include:

• Security threats and lack of investment in container security is the most common concern for container strategies.
• The highly configurable options within Kubernetes can result in security risks, and more than 9 in 10 respondents have experienced one or more Kubernetes security incident within the past year.
• DevSecOps has grown quickly over the past few years and is now a standard practice, as more than three quarters of those surveyed work in an organization with a DevSecOps initiative.
• For 62% of respondents, the role at their organization most responsible for container and Kubernetes security was DevOps or DevSecOps.

Wrapping Up

Despite security concerns, Kubernetes is growing and becoming a fundamental part of the technology stack for many large organizations. More organizations are using Kubernetes, containers, and serverless functions – and in more ways encompassing more use cases. This technology has “crossed the chasm”, moving from small-scale isolated and often vanilla deployments to becoming critical infrastructure.

If you are using container and Kubernetes, its vital to setup proper monitoring. Download a free copy of Splunk’s e-book The Modern Guide to Container Monitoring and Orchestration to learn best practices for how to setup and monitoring your Kubernetes environment.
