DevOps covers several fields of software development and implementation.
Continuous integration and continuous delivery
Continuous integration (CI) is a method in software development requiring developers to integrate their code at least one time a day. CI enables efficient and early error detection due to frequent integrations and automated testing as work progresses. Multiple daily integrations lead to an improved pace of work and reduced inconsistencies in code. Continuous delivery (CD) follows CI’s steps, automating applications delivery to scheduled environments (e.g. development and testing) and updating code changes.
Infrastructure monitoring and alarming
Continuous monitoring (ConMon) is one of the pillars of DevOps processes. The process includes control and identification of threats and issues, potentially able to compromise applications safety and stability. ConMon crowns the DevOps pipeline, facilitating resolving infrastructure issues in real-time. Stepping in once the application goes live in the production environment, continuous monitoring enables supervision and instant alerting to developers, should any issues occur.
Cloud migration and audit
Cloud solutions for business enable leveraging resources and streamlining processes, using secure servers and networks. DevOps specialists go hand in hand with cloud migration, facilitating sustainable cloud operations. DevOps input includes ensuring the safety of business cloud processes, starting with deciding on which processes to migrate, ensuring safety, incorporating containers (managed by e.g. Kubernetes) for improved security and management, followed by scheduling end-to-end cloud processes, like backups and audit to ensure quality.
In a continuous deployment approach, all code checked in the automated testing phase is released in the production environment. The process enables automated, ongoing extension of functionalities available to users in contrast to traditional release models. Continuous deployment contributes to improved productivity, faster validation of features, efficient response to market needs and customer feedback. Tools utilized in continuous deployment include but are not limited to GitLab Pipelines, Docker, Jenkins and Kubernetes.
Kubernetes clusters building and administration
Kubernetes allows cluster and container management, enabling automated application deployment and scaling. The system is a go-to DevOps tool used in cloud storage, detaching applications and services from the physical implementation.
