Why is a Devops Engineer Important in the Tech Industry? – A DevOps engineer plays a key role in the technology industry by bridging the gap between software development and IT operations. These two teams often operate in silos in a traditional software development environment. The development team builds new features, and the IT operations team focuses on maintaining and running the systems that support those features.
This separation can lead to several problems, including slow deployment cycles, misalignment between development and operations, and a lack of collaboration between the two teams.
Enter the DevOps engineer. By bringing together the expertise of software development and IT operations, a DevOps engineer can facilitate collaboration and improve the efficiency of the software development process. Consequently, DevOps engineers must be well-versed in standard system design, provisioning, and administration.
They should also be familiar with the traditional developer toolkit and techniques like using source control, performing code reviews, creating unit tests, and agile principles. DevOps engineers are responsible for designing, implementing, and maintaining the tools and processes that allow development and IT operations to work together smoothly. Here is a deeper look into these roles:

They automate the software delivery process.
One of the primary obligations of a DevOps engineer is to optimize the software delivery process. This includes automating the development, testing, and launching of code and the provisioning and configuration of infrastructure.
Automation helps reduce the time it takes to deploy new code, allowing organizations to deliver new features and updates to their customers more quickly. It also helps to eliminate manual errors and reduce the risk of downtime as the deployment process becomes more predictable and repeatable.
They boost the reliability and scalability of systems.
In addition to automation, DevOps engineers also focus on improving the reliability and scalability of systems. This may involve implementing monitoring and alerting systems to help identify and resolve issues quickly. Other roles include designing and implementing failover and disaster recovery systems to ensure that systems remain available even in the event of a failure.
Many conventional system administrators have expertise in creating shell scripts to automate tedious operations. In addition to building automation scripts, a DevOps engineer should be knowledgeable in advanced software development techniques. That includes applying agile development processes, such as code reviews and source control.
They serve as a bridge between development and IT operations
Another key aspect of a DevOps engineer’s role is facilitating communication and collaboration between development and IT operations. This involves working closely with developers, operations teams, and other stakeholders to ensure everyone is aligned on goals and objectives.
A DevOps engineer also ensures clear communication and cooperation between different teams. This may involve establishing processes for code review and testing and creating tools and systems that allow development and IT operations to work together more effectively.
DevOps engineers help break down the barriers between development and IT operations by fostering a culture of collaboration and shared responsibility. They encourage the two teams to work together towards a common goal. According to Michael Page Hong Kong, DevOps engineers should have strong interpersonal skills because they collaborate across organizational silos to foster a more collaborative workplace.
They facilitate infrastructure provisioning and administration.
The servers, storage, and networking resources needed to host applications are part of infrastructure provisioning and system administration. It is a significant role for a DevOps engineer. This role may involve controlling virtualization software, storage devises, switches and physical servers in a data center for enterprises with on-premise resources. For a hybrid or fully cloud-based business, this often involves deploying and administering virtual versions of the same components.
An expert in DevOps will be familiar with system administration, including:
- Managing internal and external network connectivity
- Security monitoring,
- Server provisioning and management
- Database deployment
- System patching.
Whether on-premises or in the cloud, a DevOps engineer should be able to plan, set up, and oversee computer ecosystems. It’s critical to comprehend Infrastructure as Code (IaC), an IT management methodology that uses best practices from DevOps software development to manage cloud infrastructure resources. A DevOps engineer should be familiar with Terraform, AWS CloudFormation, and Amazon Web Services (AWS) to create system architecture in the cloud.
They perform release engineering.
The labor necessary to create and distribute application code is a part of release engineering. The specific tools and procedures vary considerably based on several factors, including:
- The programming language used in the code
- The degree to which the pipeline has been automated
- Whether the production infrastructure is on-premises or in the cloud.
For a DevOps engineer, release engineering may involve choosing, setting up, and maintaining CI/CD tools or creating and maintaining custom build and deploy scripts. They release new tech features and ensure post-release sustainability.
DevOps processes depend on using the appropriate tools; therefore, a DevOps engineer needs to be knowledgeable about and proficient with a wide range of tools. These technologies cover the entire DevOps lifecycle, from infrastructure and development to monitoring and service operation.
They test new software.
The role of a DevOps engineer in software testing is to ensure that the testing process is integrated and automated as part of the overall software development and delivery process. This involves using tools and techniques such as continuous integration, continuous delivery, and automated testing. That is to ensure that code is tested and deployed reliably and efficiently.
A DevOps engineer may also be responsible for setting up and maintaining the testing infrastructure. That includes configuring test environments, selecting and implementing testing tools, and defining and enforcing testing standards and best practices. In addition to automation and infrastructure, a DevOps engineer may also be involved in the actual execution of software tests.
In summary, the role of a DevOps engineer is critical in the technology industry. They help bridge the gap between software development and IT operations, improve the efficiency and reliability of systems, and facilitate collaboration between the two teams. DevOps engineers play a key role in enabling organizations to deliver high-quality software and services to their customers. They achieve that by bringing together the skills and expertise of development and IT operations.
