Container technology is a lightweight, executable unit of
software that packages application code and dependencies, such as binaries,
libraries, and configuration files, to facilitate deployment in various
computing environments. It is often referred to as operating system
virtualization, where you can run a program, mini-service, or application.
Common container types.
Container technology has expanded greatly in recent years.
Hundreds of organizations have adopted container technology to speed up
application development and deployment. There are a variety of containerized
options for organizations to choose from; Here are some common types of
containers:
Docker - A popular open source platform that allows
developers to compile an application in an isolated environment called a
container. Docker uses the capabilities of the Linux kernel.
CRI-O - An open source lightweight container engine created
by Red Hat. It is the first implementation of CRI (Container Runtime Interface)
and replaces Docker as the runtime engine for Kubernetes, Google's popular
container orchestration system. Kubernetes can use any OCI (Open Container
Initiative) compliant runtime with CRI-O.
rktlet: A Kubernetes CRI (Container Runtime Interface)
implementation that aims to compete with Docker. It uses rkt (or
"rocket") developed by CoreOS as the main runtime for containers.
Rocket takes a security-first approach to address specific vulnerabilities in
early versions of Docker and utilizes many features of Linux servers. @smarttechpros

Containerd: A Windows and Linux daemon from the Cloud Native
Computing Foundation. Containerd can manage the entire lifecycle of container
technology, from image migration to container implementation and beyond. The
containerd cri plug-in allows developers to use it as a Kubernetes runtime
container.
runC:runC, a lightweight OCI-compliant container runtime,
was initially developed as part of Docker. It has now been developed into a
standalone command line tool that builds and runs containers according to the
OCI specification.
What is container control?
Container monitoring is the process of analyzing the performance of containerized applications by collecting metrics, traces, and other data. It provides information about whether the application meets the required goals and ensures optimal performance. Supplying a container and taking it out is a quick process. The temporary nature of containers makes it difficult to track down issues, especially in high-volume container environments. Container monitoring is essential to ensure a smooth running of the application with maximum uptime.
Automated monitoring tools can effectively assist container
tracking with real-time insights, alert capabilities, and actionable inputs.
Container monitoring tools analyze the entire container infrastructure,
including hosts, dependencies, and deployments. These tools can also provide
detailed information about CPU, uptime, etc., for each container to detect and
isolate the source of problems. Some tools have intuitive dashboard
capabilities to help predict capacity depletion and allow users to manage
resources efficiently.

Container vs. Virtual Machine
Containers and virtual machines differ from each other in
several ways. The container virtualizes the kernel of the host operating system
(OS) and deploys different applications on a single operating system. This
provides a consistent deployment environment for applications at every stage of
the software development life cycle (SDLC). The container is lightweight and
only packages the dependencies needed to run a container application, resulting
in low memory consumption and high portability. Cluster management tools are
used to organize content, which automate deployment, management, scaling, and
networking of containers. Popular cluster management tools include Kubernetes,
Apache Mesos, and Docker Swarm.
In contrast, a virtual machine (or VM) emulates a physical
computer system with its CPU, memory, disks, etc. Virtual machines are virtual
computers and can run multiple operating systems on a single information system. @techgeeksblogger
