Terraform, Jenkins, Kubernetes, and Linux are foundational tools in modern cloud and DevOps environments. Terraform enables infrastructure as code (IaC), allowing for the automated provisioning and management of cloud and hybrid environments through declarative configurations. Jenkins is an automation server that facilitates continuous integration and continuous delivery (CI/CD) pipelines, automating the building, testing, and deployment of code. Kubernetes is a container orchestration platform that automates the deployment, scaling, and management of containerized applications, making it essential for cloud-native and microservices architectures. Lastly, Linux serves as the backbone for many cloud platforms and servers, providing a stable, secure, and flexible operating system for managing large-scale infrastructures. Together, these technologies streamline cloud infrastructure management and enhance development efficiency.
