The key to mainframe DevOps success is in quickly identifying and removing major bottlenecks in the application delivery lifecycle. Major challenges include collaboration between mainframe and distributed teams, lack of visibility into the impact of software changes, and limited resource flexibility with scaling out necessary testing initiatives. Now let's take a closer look at some of these key challenges and how IT departments can address them ...
DevOps adoption is growing, according to the RightScale 2016 State of the Cloud Survey: DevOps Trends.
Highlights of the report include:
DevOps is growing, especially in the enterprise
DevOps adoption increased from 66 percent in 2015 to 74 percent in 2016. DevOps adoption is strongest in the enterprise (81 percent of enterprises adopting DevOps compared to 70 percent in SMBs). Enterprises are adopting DevOps from the bottom up: Adoption of DevOps by projects or teams (29 percent) and business units or divisions (31 percent) is more common than company-wide adoption (21 percent).
DevOps users use multiple tools
Less than half (43 percent) of companies are using a configuration tool. Use of multiple configuration tools is more common (25 percent) than a single configuration tool (18 percent) and 67 percent of companies using Chef or Puppet also use the other tool. Configuration tools are also often used with Docker; 80 percent of Docker users also leverage at least one configuration tool.
Container adoption is maturing, especially in enterprises
Overall, 26 percent of respondents have workloads already running in containers (8 percent in development, 18 percent in production). 36 percent of respondents are experimenting with containers, while 25 percent are learning about containers. Enterprises are using containers more than SMBs. 29 percent of enterprises have workloads running in containers versus 24 percent of SMBs, and 41 percent of enterprises are experimenting as compared to 33 percent of SMBs.
Docker seeing greatest adoption in Europe, with tech companies, and with enterprises
Evaluating Docker adoption across different geographies, industries, and roles, RightScale found that current use of Docker is heaviest among tech organizations (32 percent), enterprises (29 percent), and developers (28 percent). Use of Docker in Europe (34 percent) is also well above average.
Significant interest in containers on bare metal
Containers are currently being deployed primarily on virtual machines (29 percent) versus bare metal (12 percent). There is significant interest in deploying containers on bare metal with 24 percent of respondents having plans to do so in the future. Most containers are built using traditional Linux distributions such as Ubuntu (43 percent), CentOS (39 percent), and Red Hat (37 percent). CoreOS (12 percent) is the most widely adopted of the minimalist operating systems, which are designed specifically for containers.
Biggest challenge with containers is lack of experience for newbies
For respondents who are not currently using containers, lack of experience was by far the top challenge (39 percent). The top challenges cited by respondents who are already using containers were security (29 percent) and immature technology (29 percent).
Container focus in 2016 is education and experience
The top container initiative in 2016 will be getting more educated (62 percent), followed by conducting more experiments with containers in dev/test (44 percent) and production (28 percent), as well as expanding container use in dev/test (28 percent).
Survey Methodology: RightScale conducted its annual State of the Cloud Survey and RightScale State of the Cloud Report: DevOps Trends in January 2016. The survey questioned technical professionals across a broad cross-section of organizations about their adoption of cloud computing. The 1,060 respondents range from technical executives to managers and practitioners and represent organizations of varying sizes across many industries. Their answers provide a comprehensive perspective on the state of the cloud today. The margin of error is 3.07 percent.
