Containerization Technology

Delve into the past of containerization technology the benefits of using container technology, and the different varieties of containerization.

Containerization Explained

Containerization is the bundling of software code with only the operating system and dependencies needed for running the code to build a sole featherweight executable — known as a container — that runs constantly on any infrastructure.

They are very mobile and robust compared to virtual machines (VMs). containers are currently the existing computing units for modern cloud-native applications.

Containerization grants developers fast and secure creation and deployment of applications. With convention practices, the development of code takes place in a particular computing setting which, when moved to a different location, the frequent outcome is bugs and errors. For instance, when a developer moves code from a desktop PC to a virtual machine (VM) or from a Linux to a Windows operating system.

Containerization stamps out this headache by packaging the application code collectively with the corresponding configuration files, libraries, and dependencies needed for it to run. This sole bundling of software or “container” is engrossed away from the host operating system, and so, it stands solely and becomes mobile — capable of running across all platforms or cloud unrestrained of problems.

History of Containerization Technology

The idea of containerization and process desolation is really decades old, however the rise in 2015 of the open-source Docker engine — an industry standard for containers with straightforward developer tools and a comprehensive bundling approach — sped up the endorsement of this technology.

In our ultramodern society, organizations are increasingly using containerization for creating new apps, and for modernizing existing apps for the cloud. Containers are frequently known as “featherweight”, which means they share identical machines’ operating systems inside each app.

Containers are innately smaller in size compared to VMs and need less start-up time, permitting the running of additional containers on similar computing volume as a sole VM. This pushes higher server performance and, as a result, decreases server and licensing costs.

Possibly the most important function of containerization is that it allows it to be “written once and you can run them anywhere”. This mobility accelerates development, averts cloud vendor lock-in, and gives other evident advantages like fault isolation, easy management, and streamlined security.

Advantages Described

Containers provide compelling advantages to developers and development teams. Among them are the following:

Mobility — A container builds an executable bundle of software that is detached from the host operating system, and therefore, is mobile and capable of running across any platform or cloud.

Dexterity — The open-source Docker engine for operating containers began the industry standard for containers with easy-to-use developers tools and a comprehensive bundling style that works on both Linux and Windows operating systems. The container environment shifted to engines administered by the open container initiative (OCI). Software developers can carry on utilizing agile or DevOps tools for faster app development and improvement.

Fault Isolation — Each containerized app is isolated and operates individually from others. If one container fails, it doesn’t affect the other containers. Development teams can pinpoint and rectify technical glitches within a container hence preventing downtime in unaffected containers. In addition, the container engine can leverage any operating system isolation techniques like SELinux access control for isolating faults in containers.

Easy management — A container orchestration platform automates the installation, scaling, and management of containerized workloads and services. Container management platforms ease the management of tasks like scaling containerized apps, releasing new app versions, granting monitoring, logging, and debugging among other functions. Kubernetes is perhaps the best-known container orchestration system available.

It’s an open-source technology (initially open-sourced by Google, based on their internal project Borg) that automates Linux container operations. Kubernetes works with many container engines like Docker, but it also works with any container system that conforms to the open container initiative (OCI) standards for image formats and runtimes.

Security — The dissolution of apps as containers innately blocks the infiltration of malicious code from affecting other containers or the host operating system. Furthermore, security authorization can be automatically defined to block undesired components from getting into containers or restrict communication with irrelevant resources.

Varieties of Containerization

The accelerated growth in interest and usage of container-based solutions led to the need for standards around container technology and the approach towards bundling software code. The open container initiative, established in June 2015 by Docker and other industry leaders, is promoting ordinary, minimum, open standards around container technology. Because of this, the OCI is helping broaden open-source engine choices.

Users won’t be locked into a specific vendor’s technology, but rather they will be able to take advantage of OCI-certified technology that permits them to create containerized apps using a distinct set of DevOps tools and run these consistently on the infrastructure of their choice.

In our present-day, Docker is one of the most popular and highly utilized container engine technologies, but is it the only option available? No! The environment is standardizing on containerized and other alternatives like CoreOS rkt, Mesos container, LXC Linux container, OpenVZ, and crio-d.

To Summarize…

Containerization erases the requirement for a whole operating system for each app. Mobility, dexterity, fault isolation, easy management, and security are among the advantages of using containerization technology.

An enterprise container platform gives orchestration across numerous public and private clouds, to merge your environments for enhanced business performance and operational efficiency. It’s a crucial component of an open hybrid cloud strategy that lets you avoid vendor lock-in, build and run workloads anywhere with uniformity, and improve and remodel your IT.
