Containers

For solution providers, the rise of containers will affect everything from the number of servers firms need to the demand for tools to manage containers.

78% of respondents are using or planning to use Docker, 24% are opting for Linux containerization technology in the form of LXC and 16% said they are planning to use rkt as an alternative to Docker containers.

86% are using containers for development and 64% for testing. Surprisingly, 40% report they are using containers in production environments.

The scope of container usage spans from one to 10 hosts (27%), to 11 to 50 hosts (29%), to more than 250 hosts (21%).

Nearly half (46%) said they plan to run containers on EC2 Amazon Linux, while 45% use or plan to use Ubuntu/Debian. Roughly a quarter selected CentOS and RedHat Enterprise Linux.

Among respondents who are not already using containers, more than 80% intend to adopt containers; 11% plan to adopt containers within the next three months and 35% plan to adopt them within the next six months.

More than half (53%) said they intend to adopt containers in production within the next six to 12 months.

85% said the main driver for moving to a containerized infrastructure is that containers make it faster and easier to deploy applications. More than six in 10 (62%) cited flexibility in deployment.

54% cited better isolation as another reason for choosing containers. Containers are designed to isolate processes by encapsulating dependencies. Each container runs on a shared host OS but is isolated from the OS and any other containers running on the same host OS.

48% of the respondents indicated that a desire to move to a microservices architecture was a motivating factor in their decision to adopt containers.

30% said cost was a motivating factor in adopting containers. Containers help drive significant gains in IT infrastructure utilization.

56% said the biggest barrier to moving to a containerized infrastructure is the technology’s maturity; 50% indicated that orchestration is a challenge when adopting containers, while 46% said monitoring and 40% said automation posed additional barriers to adoption.
