Survey Shows Jenkins is Mission-Critical Platform for Application Development

The Jenkins Community, the community of developers using the Jenkins CI open source continuous integration (CI) server, today announced that a recent survey showed community participants consider Jenkins to be crucial to their development processes and continue to be satisfied with Jenkins resources. The survey was conducted by CloudBees, on behalf of the Jenkins community.

In the survey of 721 development professionals, 83 percent of respondents described Jenkins CI as a mission-critical core development tool, deeply entrenched in the software development process. An overwhelming majority of respondents – 87 percent – also said they were “satisfied” or “very satisfied” with Jenkins, underscoring the value they are experiencing using Jenkins resources in their development initiatives.

According to metrics provided separately by the Jenkins community, growth in active installations of Jenkins CI has grown by more than 65 percent over the past year to over 53,000 installations. “The survey results drive home the point that Jenkins provides a critical service to users and that usage of it is growing rapidly,” said Kohsuke Kawaguchi, founder and member of the interim Jenkins Governing Board. “People love Jenkins, they appreciate the enhancements the Jenkins community is continually producing and they are willing to participate in, and contribute to, the project.”

One of the key strengths of Jenkins is its extensibility. Plugins to meet custom needs are easily created and, as a result, an ecosystem of 636 plugins is now available for Jenkins. Plugins exist to support the building and testing of virtually any project – ranging from enterprise Java applications to embedded C++ applications. Additionally, the number of plugins is growing by an average of one new plugin every other day. The survey showed 11 percent of respondents have created an open source plugin for the community – a high number for an open source project, reflecting the ongoing developer engagement in the Jenkins project. Another 7 percent have written an in-house plug-in to meet company-specific requirements within their own development environments, and a total of 60 percent say they’re either interested in contributing a plugin or have contributed one already.

While use of Jenkins is increasing in companies of all sizes, growth is strongest in enterprise environments. The survey showed about 69 percent growth in the number of respondents that indicated they work for companies with 1,000 developers or more (13.5 percent in 2012 vs. 8 percent in 2011).

Although Jenkins has always been well-entrenched within the Java community, with 74 percent of respondents using Java, the survey showed a significant use of other languages, too. Several popular programming languages used by developers within the community include C/C++ (38 percent), JavaScript (35 percent), Python (29 percent), C# (25 percent) and PHP (18 percent).

The online survey was launched at the Jenkins User Conference in San Francisco on September 30 and concluded on October 31, 2012. It was promoted on, the Jenkins Wiki, the CloudBees blog, various LinkedIn groups and other forums and social media channels.

The survey showed all types of job profiles are interested in Jenkins, with developer being listed as the most common job role (71 percent), followed by build manager (41 percent), software architect (24 percent) and DevOps professional (21 percent).

Priorities for future development expressed by the community include quality improvements and timely bug fixes, more documentation and examples, and the creation of new plugins to address specific functionality.

The survey showed Jenkins users are moving some functions to the cloud as companies increasingly realize the benefits of cloud resources for application development. Twenty-one percent are using source control management tools in the cloud, 26 percent are deploying applications to a cloud infrastructure and 13 percent are using or planning to use Jenkins in the cloud.

The Internet of Everything is re-shaping technology trends–moving away from “request/response” architecture to an “always-on” Streaming Web where data is in constant motion and secure, reliable communication is an absolute necessity. As more and more THINGS go online, the challenges that developers will need to address will only increase exponentially. In his session at @ThingsExpo, Todd Greene, Founder & CEO of PubNub, exploreed the current state of IoT connectivity and review key trends and technology requirements that will drive the Internet of Things from hype to reality.
Two weeks ago (November 3-5), I attended the Cloud Expo Silicon Valley as a speaker, where I presented on the security and privacy due diligence requirements for cloud solutions. Cloud security is a topical issue for every CIO, CISO, and technology buyer. Decision-makers are always looking for insights on how to mitigate the security risks of implementing and using cloud solutions. Based on the presentation topics covered at the conference, as well as the general discussions heard between sessions, I wanted to share some of my observations on emerging trends. As cyber security serves as a fou...
Continuous processes around the development and deployment of applications are both impacted by -- and a benefit to -- the Internet of Things trend. To help better understand the relationship between DevOps and a plethora of new end-devices and data please welcome Gary Gruver, consultant, author and a former IT executive who has led many large-scale IT transformation projects, and John Jeremiah, Technology Evangelist at Hewlett Packard Enterprise (HPE), on Twitter at @j_jeremiah. The discussion is moderated by me, Dana Gardner, Principal Analyst at Interarbor Solutions.
Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
The Internet of Things is clearly many things: data collection and analytics, wearables, Smart Grids and Smart Cities, the Industrial Internet, and more. Cool platforms like Arduino, Raspberry Pi, Intel's Galileo and Edison, and a diverse world of sensors are making the IoT a great toy box for developers in all these areas. In this Power Panel at @ThingsExpo, moderated by Conference Chair Roger Strukhoff, panelists discussed what things are the most important, which will have the most profound effect on the world, and what should we expect to see over the next couple of years.
With all the incredible momentum behind the Internet of Things (IoT) industry, it is easy to forget that not a single CEO wakes up and wonders if “my IoT is broken.” What they wonder is if they are making the right decisions to do all they can to increase revenue, decrease costs, and improve customer experience – effectively the same challenges they have always had in growing their business. The exciting thing about the IoT industry is now these decisions can be better, faster, and smarter. Now all corporate assets – people, objects, and spaces – can share information about themselves and thei...

I recently attended and was a speaker at the 4th International Internet of @ThingsExpo at the Santa Clara Convention Center. I also had the opportunity to attend this event last year and I wrote a blog from that show talking about how the “Enterprise Impact of IoT” was a key theme of last year’s show. I was curious to see if the same theme would still resonate 365 days later and what, if any, changes I would see in the content presented.
Apps and devices shouldn't stop working when there's limited or no network connectivity. Learn how to bring data stored in a cloud database to the edge of the network (and back again) whenever an Internet connection is available. In his session at 17th Cloud Expo, Ben Perlmutter, a Sales Engineer with IBM Cloudant, demonstrated techniques for replicating cloud databases with devices in order to build offline-first mobile or Internet of Things (IoT) apps that can provide a better, faster user experience, both offline and online. The focus of this talk was on IBM Cloudant, Apache CouchDB, and ...
Microservices are a very exciting architectural approach that many organizations are looking to as a way to accelerate innovation. Microservices promise to allow teams to move away from monolithic "ball of mud" systems, but the reality is that, in the vast majority of organizations, different projects and technologies will continue to be developed at different speeds. How to handle the dependencies between these disparate systems with different iteration cycles? Consider the "canoncial problem" in this scenario: microservice A (releases daily) depends on a couple of additions to backend B (re...

Discussions of cloud computing have evolved in recent years from a focus on specific types of cloud, to a world of hybrid cloud, and to a world dominated by the APIs that make today's multi-cloud environments and hybrid clouds possible. In this Power Panel at 17th Cloud Expo, moderated by Conference Chair Roger Strukhoff, panelists addressed the importance of customers being able to use the specific technologies they need, through environments and ecosystems that expose their APIs to make true change and transformation possible.
Container technology is shaping the future of DevOps and it’s also changing the way organizations think about application development. With the rise of mobile applications in the enterprise, businesses are abandoning year-long development cycles and embracing technologies that enable rapid development and continuous deployment of apps. In his session at DevOps Summit, Kurt Collins, Developer Evangelist at, examined how Docker has evolved into a highly effective tool for application delivery by allowing increasingly popular Mobile Backend-as-a-Service (mBaaS) platforms to quickly crea...
The Internet of Things (IoT) is growing rapidly by extending current technologies, products and networks. By 2020, Cisco estimates there will be 50 billion connected devices. Gartner has forecast revenues of over $300 billion, just to IoT suppliers. Now is the time to figure out how you’ll make money – not just create innovative products. With hundreds of new products and companies jumping into the IoT fray every month, there’s no shortage of innovation. Despite this, McKinsey/VisionMobile data shows "less than 10 percent of IoT developers are making enough to support a reasonably sized team....
As organizations realize the scope of the Internet of Things, gaining key insights from Big Data, through the use of advanced analytics, becomes crucial. However, IoT also creates the need for petabyte scale storage of data from millions of devices. A new type of Storage is required which seamlessly integrates robust data analytics with massive scale. These storage systems will act as “smart systems” provide in-place analytics that speed discovery and enable businesses to quickly derive meaningful and actionable insights. In his session at @ThingsExpo, Paul Turner, Chief Marketing Officer at...
The cloud. Like a comic book superhero, there seems to be no problem it can’t fix or cost it can’t slash. Yet making the transition is not always easy and production environments are still largely on premise. Taking some practical and sensible steps to reduce risk can also help provide a basis for a successful cloud transition. A plethora of surveys from the likes of IDG and Gartner show that more than 70 percent of enterprises have deployed at least one or more cloud application or workload. Yet a closer inspection at the data reveals less than half of these cloud projects involve production...
