Containers are essentially like lightweight and portable virtual machines. They provide a way to package an application's code, configurations, and dependencies into a single image, alongside the operating system, that can be easily shared and run in any environment.
You can use Docker, the most popular containerization platform, to create a container image. The image defines the dependencies, OS and runtime. You can use the image to spawn a container on any computer or server with Docker installed. This makes it easy to develop and deploy applications in a consistent and reproducible way, regardless of the underlying infrastructure.

Kubernetes (k8s)
Kubernetes is an open-source platform that automates container operations, enabling developers to deploy, scale, and manage containerized applications easily.
Monitoring
Monitoring is the act of tracking the performance and behavior of a system, application, or service in real-time, allowing for the detection of issues, anomalies, and performance bottlenecks. It involves collecting and analyzing metrics to ensure that everything is running smoothly and to identify potential areas for improvement.
Autoscaling
Autoscaling is the ability of an application to automatically adjust its resources based on real-time demand, ensuring optimal performance and cost-efficiency. This enables applications to dynamically scale up or down in response to changes in traffic, without manual intervention.
