Study Notes

Overview of DevOps

DevOps combines development (Dev) and operations (Ops) to improve collaboration and deliver software updates rapidly and with high quality.
Emphasizes both speed and quality in software development.

Development and Operations Teams

Development Team: Responsible for writing, editing, and documenting code, managing it in a code repository.
Operations Team: Manages infrastructure (hardware, software, network, cloud storage), deploys software updates, and supports the code.

Key Goals of DevOps

Speed: Focuses on quick and frequent delivery of small updates rather than infrequent large releases.
Quality: Ensures deliverables meet stakeholders' requirements for performance, stability, security, and availability.

DevOps Culture

Encourages collaboration between development and operations teams, breaking down silos.
Promotes open communication throughout the Software Development Lifecycle (SDLC), ensuring quick feedback on issues.
Both teams share responsibility for product quality, integrating testing and maintenance into the development process.

Agile Methodology

Agility: Adopted for software development, fostering flexibility and adaptability.
Unlike the linear Waterfall Approach, agile development is iterative, involving short cycles (sprints) for quicker client feedback and continuous testing.
Helps identify and address issues early, enhancing overall product quality.

Microservices Architecture

Emphasizes a modular design where applications consist of small, independently functioning components (microservices).
Facilitates faster updates; instead of redeploying a large application, developers modify only relevant components, reducing risk and deployment time.

Automation in DevOps

Employs tools to automate processes within the SDLC, such as testing and deployment.
Automation minimizes human error, accelerates deployment, and allows teams to focus on core development tasks.

CI/CD Processes

Continuous Integration (CI): Regularly integrates small code changes into the main code base, followed by automated testing and review.
Continuous Delivery (CD): Sends approved code to a preproduction environment for final testing before deployment.
CI/CD streamlines the testing and integration process, enabling faster and safer production releases while maintaining high-quality standards through frequent testing and security checks.
