DevOps is not just about technical prowess, soft skills play a crucial role. Discover the interpersonal skills that set successful DevOps professionals apart, fostering effective communication, collaboration, and problem-solving.

DevOps can be best explained as people working together to conceive, build and deliver secure software at top speed. DevOps practices enable software development (dev) and operations (ops) teams to accelerate delivery through automation, collaboration, fast feedback, and iterative improvement.

DevOps focuses on incremental development and rapid delivery of software. Success relies on the ability to create a culture of accountability, improved collaboration, empathy, and joint responsibility for business outcomes.

DevOps is a combination of software development (dev) and operations (ops). It is defined as a software engineering methodology that aims to integrate the work of development teams and operations teams by facilitating a culture of collaboration and shared responsibility.

Key Aspects >

The DevOps methodology is built on four key principles that drive the efficiency and effectiveness of application development and deployment, embracing the best aspects of modern software development:

1. Automation of the Software Lifecycle:

   • Streamlining the entire software development lifecycle by automating tasks such as testing, builds, releases, and the setup of development environments. This minimizes delays and reduces the risk of human error in delivering software.

2. Collaboration and Communication:

   • Beyond automation, a standout DevOps team prioritizes effective collaboration and communication. Seamless teamwork is crucial for success in adopting DevOps practices.

3. Continuous Improvement and Waste Reduction:

   • Striving for ongoing enhancement and efficiency gains, from automating repetitive tasks to monitoring performance metrics. High-performing DevOps teams consistently seek opportunities to minimize waste and improve processes.

4. Hyperfocus on User Needs with Short Feedback Loops:

   • By leveraging automation, enhancing communication and collaboration, and continually refining processes, DevOps teams can dedicate time to understand and address real user needs. Short feedback loops enable quick adjustments to meet user expectations.

DevOps platform & tools >

Selecting tools that support your processes is critical for DevOps to be successful. If your operations are going to keep pace with rapid development cycles they’ll need to use highly flexible platforms and treat their infrastructure like dev teams treat code. Manual deployments are slow and leave room for error.

Platform provisioning and deployment can be simplified through automation.

Site reliability engineering (SRE) takes these manually operations tasks and manages them using software and automation. An SRE approach can further support the goals of a DevOps team.

Containers make it easier to move applications between development, testing, and production environments. Using containers lets developers package and isolate their apps with everything they need to run, including application files,

runtime environments, dependent libraries and configurations.

DevOps and Kubernetes >

DevOps and Linux containers work together seamlessly. Linux containers provide the essential technology for cloud-native development, offering a unified environment for tasks like development, delivery, integration, and automation.

Kubernetes is the contemporary solution for automating operations with Linux containers. It simplifies the management of clusters running Linux containers on public, private, or hybrid clouds, making it easy and efficient.

Phases >

As DevOps has grown, it's become more complex due to two main reasons:

1. Shift to Microservices: Organizations are moving from large, all-in-one systems (monolithic architectures) to more modular, smaller services (microservices architectures).

2. Increased Tool Usage: With the maturation of DevOps, organizations find themselves using a growing number of DevOps tools for each project.

This complexity has led to a surge in integrations between projects and tools. This evolution occurred in four phases:

1. Bring Your Own DevOps:

   • Each team selected its own tools. This caused issues when teams collaborated because they weren't familiar with each other's tools.

2. Best-in-class DevOps:

   • Organizations standardized on a set of tools, with one preferred tool for each stage of DevOps. While it improved collaboration, moving software changes through different tools became a problem.

3. Do-it-yourself DevOps:

   • Organizations adopted a DIY approach, customizing and integrating their point solutions. However, this resulted in challenges, with tools not fitting seamlessly and increased maintenance efforts.

4. DevOps Platform:

   • A unified platform improves team efficiency. This approach replaces DIY DevOps, providing visibility and control over all DevOps stages. GitLab's DevOps platform is a single application with a consistent interface, adaptable for self-managed or SaaS deployment. It resolves inefficiencies and vulnerabilities associated with a patchwork DIY toolchain.
