It is said that DevOps is about to finish what the Agile has started.
So much has been written about DevOps but still there are plenty of interpretations. The common understanding is that DevOps is about collaboration between Development and Operations teams.
But why the collaboration is so necessary?
A possible answer lies in the Agile movement for shipping software which imposes fast pace development and short delivery cycles. One would ask then, why we need short delivery cycles and fast pace development. The answers may vary for different organizations but it is a known truth that being first on the market is a huge competitive advantage. It is priceless to be able to address software issues in a timely manner while providing continuous value stream to your customers. This is valid for all organizations and especially for SaaS and PaaS vendors.
Well, if DevOps is about collaboration between Dev and Ops, how this can be put in practice? How can an organization begin to experience real benefits?
Continuous Delivery – essential building block of DevOps
Continuous Delivery is an emerging software development methodology that automates and improves software delivery. By building the capability to rapidly, reliably, and repeatedly push out enhancements and bug fixes to customers at low risk and with minimal manual overhead, software development organizations can respond to business needs faster and improve satisfaction for business stakeholders and end users alike.
Continuous Delivery Process
1. Code – Implement User Stories
2. Build – Usually in this phase code is compiled, static code analysis is run and units test are executed.
3. Test – Run Acceptance Tests a.k.a end to end scenario tests to validate the software being built
4. Deploy – Deploy the system into environment
