What Is DevOps?
DevOps is not a framework or a workflow, it’s a culture which is taking over the business World.
In many organisations, Development (Dev) and Operations (Ops) have misaligned objectives. Dev is often measured by the number of new features released, whereas Ops is measured by 100% uptime. What is the sure-fire way to get 100% uptime? You don’t ever introduce any new features or make any changes.
I bet you are thinking “How do we keep up with the demand for new features and technologies, while maintaining stability and high performance?” Well, DevOps is the answer! DevOps allows companies to focus on what truly matters, how to deliver maximum value to both customers and stakeholders.
How do you successfully start a DevOps transformation? You can use the DevOps “CALMS” model… The “CALMS” model is an abbreviation, which stands for:
C = Culture
Create a culture of collaboration and ownership within the organisation.
A = Automation
Allow information to guide your decisions and get quick feedback utilising automation.
L = Lean IT
Move towards the Lean IT way of thinking and understand the difference between being busy and being valuable.
M = Measurement
Learn how to be empirical and let statistics guide, but not at the expense of culture.
S = Sharing
Share your goals with others to create purpose and talk about your experiences to encourage learning within the organisation.
With DevOps, changes can make it to production faster, resources are easier to share, and large-scale systems are both easier to manage and maintain. The power of DevOps can only be fully realised when the organisation embraces the values and principles of DevOps.
Why Is DevOps So Important?
There is unprecedented consumer demand, customers want it now and are better informed than ever before. We all need to quickly learn how to become more responsive to:

DevOps and Agile practices will enable us to be hyper-responsive through:
• Reducing time to market.
• Improving reliability, security, quality and performance.
• Fostering a culture of innovation and excellence at every step.
The DevOps Research Assessment (DORA) concluded that the teams who adopted DevOps practices benefited from less deployment pain and burnout as well as faster releases, with both speed and stability that statistically impact business performance.
So, high performance IT powers high-performance business.
