Rancher Labs released Wednesday highlights of a survey of 1,106 tech users at large and small enterprises across a broad range of more than 25 industries, including technology, financial services, telecom, education, government and healthcare. The respondents were almost evenly split among EMEA and North America.
The results of the survey illustrate rapid adoption of containers and Kubernetes. Key findings include 85 percent of respondents are running containers in production; with Kubernetes emerging as the standard for container management with 90 percent of respondents using it for orchestration.
Architects, developers, and DevOps are the primary drivers of adoption (69 percent) followed by IT operations (30 percent), while multiple cluster environments are becoming the norm with 91 percent of respondents running multiple clusters, and 45 percent planning multiple clusters within six months.
The most common use cases for containers are designing microservices (71 percent), building customer facing applications (70 percent), and modernizing legacy applications (53 percent). Hybrid cloud deployments are prevalent with 71 percent of respondents running on-premises workloads, while 67 percent are running cloud-based applications. Edge is emerging as an important use-case with 15 percent of respondents deploying containers for edge workloads
As with any rapidly emerging technology, the survey also indicates that challenges remain, including complexity remains a barrier to entry with more than 62 percent of respondents not currently running containers citing that as the primary reason slowing adoption, while Windows container adoption is limited, although this is not surprising given Windows container support was only introduced in Kubernetes earlier this year.
Users are still wary of persistent storage due to complexity and perceived risk, while service mesh is perceived as complex which is limiting more widespread adoption.
“It’s clear from the survey results that containers have become a key pillar of modern IT strategy with 85% of respondents running containers in production,” said Peter Smails, CMO, Rancher Labs. “Additionally, 91% of respondents running more than one cluster combined with a healthy mix of on-premises and cloud-based deployments indicates multi-cluster / multi-cloud is emerging as a deployment strategy of choice.”
