The DevOps – vicious cycle


The above image depicts the DevOps vicious cycle (Define /Plan –> Construct / Build –> Execute / Run), with the landscape of Capabilities and Jungle of Tools around it.

In any enterprise (big or small), to execute any project (big or small), the steps that are followed are :

  1. Step 1 : Defining an Application or Designing a Plan for the Application by the Acount Owners
  2. Step 2 : Construction and Building of the Application by the Developer Team
  3. Step 3 : Deploying and Executing the Build/Release by the Operations Team

As the buzz word “devops”, is out in market for quite some time now, there are a “jungle of tools”, built and tagged under the DevOps category. But “Yes”, these tools can be differentiated from the way they functions and at what point in time they can be leveraged in a software execution cycle.

Some of the common capability tunnels under which these tools fall are :

  1. Release Engineering Process and Continuous Delivery
    • Jenkins, Canistrano, Glu, Hudson
  2. Environment Provisioning
    • Chef, Puppet, CF Engine
  3. Hawk Eye on the System
    • AppDynamics, BMC Software
  4. Virtualization
    • Vagrant, VMWare

…..and many more!!

There is an interesting Slideshare PPT, that talks about the different tools that are used for Devops and the confusion they create to pick, choose and implement in a project. This presentation gives a highlight of the Tools, the technology behind it, when to use and most importantly for what purpose.


Happy Learning!! 🙂


The State of DevOps (by PuppetLabs)

The State of DevOps (by PuppetLabs)

Sanjeev Sharma's Site

Puppet Labs just published the 2013 State of DevOps Report.  They surveyed over 4,000 IT practitioners to get this report and I think it is an excellent snapshot in time of the current state of DevOps. I encourage all DevOps peeps (to use a technical term) to review this report. That being said, it is a sample (a good one), and the ‘state’ of DevOps varies considerably from industry to industry and by geography and technology.

Some key findings (reproduced here without editing from PuppetLabs’ site):

Key Findings

  • DevOps adoption is accelerating. Sixty-three percent of respondents have implemented DevOps practices, compared to 50 percent in 2011—a 26 percent increase in DevOps adoption rate.
  • DevOps offers increased agility and reliability. Respondents from organizations that had implemented DevOps reported benefits in staggering numbers: More frequent software releases and improved software deployment quality were both reported by 63…
