Containerization is a form of virtualized operating system developed as a response to the many problems of hardware-level virtualization. Because the latter runs a full-blown guest operating system, it is very resource-intensive and incurs a significant amount of overhead, but containerization is much lighter. Since the containers share the host machine’s kernel, the resources are not wasted on running separate operating system tasks. This allows for a much quicker and lightweight deployment of applications.
Docker is a containerization software that is used for automating the deployment and management of applications within an isolated environment. This software allows us to “pack” and ship an application, along with all of its needed files, libraries, and dependencies, into a “docker container“. That container can then be easily ported to any Linux system that contain cgroups support within the kernel, and provides a container management environment. Docker is one of several containerization implementations (not to be confused with virtualization) based on this cgroups mechanisms built into the Linux kernel.
Minikube is the name of a software program written in Go, which can build a local Kubernetes cluster on a single host. It uses a meager amount of resources to run a mini Kubernetes deployment. Minikube is mainly used for testing purposes using different scenarios or versions of Kubernetes
In this article, we will compare the similarities and differences of a cloud server vs a physical server. Every business has similar and different approaches in how they operate. The differences often relate to what is essential for that specific business: the clientele, the need to process information/orders, and how quickly market adaptation changes are needed.
Since almost every industry today has some type of online presence, hosting providers have adapted to offer products that solve many of the challenges that face todays businesses. One such hurdle a company must solve is which type of hosting infrastructure is best suited for their demands. These choices include both cloud servers and dedicated servers. Cloud servers and dedicated servers each perform distinct tasks based on use-cases, and can be a challenge to determine which environment will satisfy the requirements that a business requires.
Before we begin, let’s describe what Docker is. Docker is a set of virtualization tools that allows us to create, test, and deploy containerized applications quickly and easily on a dedicated server. It has become very popular and used almost everywhere in our daily lives. Thanks to containerization, we can quickly launch applications on different cloud platforms utilizing small bundles which contain all the needed packages, libraries and configuration file to run an application. These docker packages communicate via established network channels.
With the constant technological development we are witnessing in the world of hosting, it is necessary to familiarize ourselves with the terminology and meaning of the systems we are using. An important distinction that we need to make is between virtual machines and containers, as they are both widely used in the hosting industry, and yet they are often confused.
