     "description": "Unit testing is a software testing method where individual components or units of a program are tested in isolation to ensure they function correctly. This approach focuses on verifying the smallest testable parts of an application, such as functions or methods, by executing them with predefined inputs and comparing the results to expected outcomes. Unit tests are typically automated and written by developers during the coding phase to catch bugs early, facilitate code refactoring, and ensure that each unit of code performs as intended. By isolating and testing each component, unit testing helps improve code reliability and maintainability.\n\nVisit the following resources to learn more:",

-    "description": "Containers are a construct in which cgroups, namespaces, and chroot are used to fully encapsulate and isolate a process. This encapsulated process, called a container image, shares the kernel of the host with other containers, allowing containers to be significantly smaller and faster than virtual machines, These images are designed for portability, allowing for full local testing of a static image, and easy deployment to a container management platform.\n\nVisit the following resources to learn more:",
+    "description": "Container orchestration is the process of managing and automating the lifecycle of containers, including their deployment, scaling, and networking across multiple hosts. It is a critical technology for running complex containerized applications in production environments.\n\nBy leveraging tools like Kubernetes, Docker Swarm, and Apache Mesos, organizations can ensure high availability, scalability, and reliability for their applications. Container orchestration simplifies operations by automating routine tasks and providing a robust foundation for microservices, cloud-native development, and DevOps practices.\n\nVisit the following resources to learn more:",
