101 on DevOps
The combination of development and operations creates the term modernly known as DevOps. It is meant to highlight the collaboration of a shared approach in performing organizational tasks between the IT team and the app development teams of the company. DevOps is a philosophy that endorses collaboration and strong communication between the teams in an organizational structure.
In scrutiny, DevOps can be defined as:
- The adoption of iterative software development,
- Automation,
- Programmable infrastructure deployment, and
- Maintenance.
Any cultural alterations like building trust and cohesion between developers and systems administrators come under the DevOps umbrella. The technological projects aligned with the business requirements are also an aim of DevOps that can change software delivery chain, job roles, IT tools, services, and best practices.
Since DevOps is a philosophy that involves technology departments, there are a few common methods employed with it. Including:
- Task automation through continuous integration or continuous deployment using CI/CD tools.
- Real-time monitoring to support the adoption of DevOps into a system. Furthermore, the adoption of products like incident management systems, collaboration platforms, and configuration management are included.
- Implementing microservices, containers, and cloud computing with DevOps methodology.
Using a DevOps approach is another way of accomplishing IT projects to meet business requirements. It can cohabit with agile software development, and other IT service management frameworks like ITIL. Lean and Six Sigma can also be used in collaboration for project management edicts of the business strategies.
What is a DevOps Process?
When a software development cycle is in process, DevOps aims at improving the efforts in each stage. Imagine the DevOps process as an infinite loop that continues forever. The loop is divided into smaller stages that include planning, coding, building, testing, releasing, deploying, operating, and monitoring. The next stage is feedback, which links to the loopback to planning.
Magnifying each stage of the process idyllically means that the IT team would create perfect software. One that ultimately meets the necessities of the user and deploys it instantly to save time. It then runs at the prime level in the first try since organizations fuse technology and culture to achieve the goal.
The expectations of the software must be aligned so the stakeholders and developers communicate about the project. Developers then work on a smaller update that does not influence the loop and go live independently. Then the question of time.
The use of CI/CD pipelines used by the IT teams avoids time delays and moves the code a step closer to deployment from development. All teams review the changes timely and implement policies that guarantee releases are aligned with the set standards.
While writing software is the easy part, the software working is another story altogether. DevOps uses containers and other methods to ensure that the written software behaves expectedly. Since the changes are deployed individually, it is easier to trace the problems as they occur. Using port-mortem investigation and feedback channels, improvement codes are created live.
Challenges & Benefits of DevOps
The benefits of using DevOps include:
- Increased communication levels between the IT groups of an organization.
- Scarcer silos
- Shorter time to release software in the market.
- The quick improvement due to immediate feedback.
- Less downtime
- Software delivery pipeline is improved via validations, builds, and deployment.
- Since it is automated, less mundane tasks for all teams.
- A broader range of skills and roles in the teams.
- Accountability, code ownership due to a streamlined development process.
The challenges are as many as the benefits, which include:
- Departmental changes in IT and organization require additional skills and job duties.
- High cost of platforms and tools. Specialized training and support teams for the efficient use of DevOps.
- The proliferation of development and IT tools.
- Unsafe automation. Often unnecessary and fragile.
- Scaling DevOps across various teams and projects.
- Compliance when role separation is required that needs regulation.
- Deployments are risky because teams have a fail-fast mentality. Jobs are generalized instead of specialized.
- Creates new bottlenecks for the organization.
DevOps Adoption
The transformation of organizations into DevOps is not instantaneous. Companies usually start with a pilot project moving in smaller stages by aligning the IT teams in setting certain KPIs. These can be agreeing on having a lower number of bugs or shorter cycles in the software development process. Organizations focusing on skill development, sharing knowledge, and creating best practices can lay the groundwork for DevOps.
The following stages can help organizations in adopting the DevOps philosophy.
- Initiation: teams are divided into silos and work is completed with ad hoc tool and process choices.
- Definition: introduction of a pilot project that aligns with the DevOps approach. This will prove the concept.
- Management: scaling the results of the pilot project and implementing with more team members and different projects.
- Measurement: once the tools and processes are set, teams can share knowledge based on refined practices. Increase in automation and tool connectivity with standards set through improved policies.
- Optimization: continuous improvement of DevOps leading to evolvement as per the requirements of different projects.
