Programmers write a code in their own way subjected to the logic they have in mind at the moment. Also a difference in technical and logical skill creates a difference in the tactic of code even with same logic, making it a good or a bad code as per the same standard. That’s how bugs are formed in a code. Many other developers read the code multiple times to understand it and fix the bugs to improve the features.
Each language possesses its unique style of coding and guidelines to compel a meaning and understanding. Most of the time, developers scratch their heads to understand the code written by some other developer of the team. Sometimes, they even find it better to write a code from the scribbles than to read someone else’s code.
A few highlights are discussed below of the issues in a code review:
Dev & Ops Mindsets
Changes are eternal in the needs of a business and developers write with a mind-set of ‘bring the change’ because that’s what they are paid for. They are often encouraged to create, innovate and generate as much change as possible.
However a business is dependent on operations to keep the lights on generating revenue by delivering the services. Ironically, Operations just hate the changes to bring the stability and reliability motivated to resist the change.
An organization must function as a whole setting aside the conflicts of developers and operations working for the common good. This is where DevOps steps inside.
Developers develop and Operations operate
To create software and applications, a developer writes and debugs codes. After deployment of the application, the developer generally, monitor its performance and gather feedback from the users to update software for a better and stable release. This defines the agenda of a developer to effectively introduce the change on a regular basis creating new software & applications and modifying existing ones for a better and innovative environment that help users to be more productive.
To make sure that everything is optimally operated, is the only objective of IT admins or IT operations by ensuring the availability of network resources and peak time functioning. Any new demand for the network resources threatens the equilibrium achieved. Ability to provide a reliable and optimized infrastructure to guarantee network resource for the change is the true measure for a traditional operations role.
Need for DevOps
Ultimately, both developers and operations seek productivity of the organization. But agendas of the two are north & south for each other. Developers create and improve software and application ASAP, and operations restrains changes from happening in the environment. Some bridge must be there between the two for an effective and efficient functioning of the organization.
Traditionally, in ops organizations, the teams are organized by their functioning and specialities such as – database administration, network administration, server administration and so on. The consequences of this rise up to the surface in complex activities as work waiting in long queues, little visibility of how the value stream and the work is related etc.
The issue get worse as the developers are focussed on speed and the operations are encouraged for reliable, secure & optimized network experience. It finally ends up with bottlenecks, delays and quality issues because of large queues, longer lead times and poor hand offs.
Role of DevOps
The profound shift from conventional IT culture to DevOps to bring the developers and operations together to march toward common goals understanding objectives of each other, working together functioning the organization as whole, is the demand of the hour.
Customers have zero tolerance toward a bad software and application and discard it at once. Smaller & frequent releases, automation tools empowering transparent communication and cooperation are what DevOps do. Developers develop as quickly as possible and operations maintain the network resources, security, reliability and optimization with a smooth flow of environment.
Transition to a DevOps culture from the traditional one requires redefined objectives in order to shift the ironic thinking of the two nodes to cooperative work on shared goals. But, the choice is running out of options. Either advance as a system as wide as the organization or die as a department.
