Containerized Applications:
Introduction
Containerized applications are applications that run in isolated packages of code called containers. Containers include all the dependencies that an application might need to run on any host operating system, such as libraries, binaries, configuration files, and frameworks, into a single lightweight executable. This makes containerized applications portable, scalable, efficient, and secure.
In this article, we will explore the benefits and challenges of containerized applications, how they work, and some of the tools and platforms that support them.
Benefits of Containerized Applications
Containerized applications offer several advantages over traditional methods of application hosting, such as physical servers or virtual machines. Some of the main benefits are:
Isolation:
Containerized applications run in their own isolated environments, which means they are not affected by other applications or system components on the same host. This reduces the risk of conflicts, errors, and security breaches.
Portability:
Containerized applications can run on any host operating system that supports containers, without requiring any changes to the application code or configuration. This allows developers to write once and run anywhere and simplifies the deployment and migration of applications across different environments.
Lightweight:
Containerized applications do not include their own operating systems, unlike virtual machines. This makes them much smaller and faster than other virtualization methods. Containers can also share common resources and layers, which reduces the overhead and improves the performance of the applications.
Scalability:
Containerized applications can easily scale up or down by adding or removing container instances, depending on the demand. Containers can also be orchestrated by tools such as Kubernetes or Docker Swarm, which automate the management and distribution of containers across clusters of hosts.

How Containerized Applications Work
Containerized applications work by running an executable package of software (the container) that includes all the application dependencies on top of a host operating system that supports containers. The containerized application has several components, such as:
-
Application code:
The application code is the source code of the application that performs the business logic and functionality. The application code can be written in any programming language or framework, such as Java, Python, Ruby, or Node.js. -
Container image:
The container image is a package of the application code and all its dependencies, such as system libraries, binaries, and configuration files. The container image is the blueprint or architecture of the container system. The container image can be built from a base image that provides the common dependencies, and then customized with additional layers that provide the specific dependencies for the application. -
Container engine:
The container engine is the software that runs and manages the containers on the host operating system. The container engine is responsible for creating, starting, stopping, and deleting containers, as well as providing networking, storage, and security features for the containers. The most popular container engine is Docker, which is based on the open-source project Moby. -
Host operating system:
The host operating system is the operating system that runs on the physical or virtual machine that hosts the containers. The host operating system provides the kernel and the resources that the containers use. The host operating system can be any operating system that supports containers, such as Linux, Windows, or macOS. -
Container orchestration platform:
The container orchestration platform is the software that coordinates and manages the containers across multiple hosts or clusters. The container orchestration platform is responsible for scheduling, scaling, distributing, and updating containers, as well as providing service discovery, load balancing, and fault tolerance features for the containers. The most popular container orchestration platform is Kubernetes, which is based on the open-source project Borg.
Many tools and platforms are available to support the development, deployment, and operation of containerized applications. Some of the most widely used ones are:
Docker:
Docker is the leading container engine that allows developers to build, run, and share containerized applications. Docker provides a commandline interface, a graphical user interface, and a REST API to interact with containers. Docker also provides a registry service called Docker Hub, where users can store and distribute container images.
Kubernetes:
Kubernetes is the leading container orchestration platform that allows operators to manage the lifecycle and scalability of containerized applications. Kubernetes provides a declarative configuration language, a control plane, and a set of APIs to interact with containers. Kubernetes also provides a registry service called Kubernetes Registry, where users can store and distribute container images.
Conclusion
Containerized applications are applications that run in isolated packages of code called containers. Containerized applications offer several benefits, such as portability, scalability, efficiency, and security, but also pose some challenges, such as complexity, security, and monitoring. Containerized applications work by running an executable package of software (the container) that includes all the application dependencies on top of a host operating system that supports containers. Containerized applications rely on various components and tools, such as the application code, the container image, the container engine, the host operating system, and the container orchestration platform. Some of the most popular tools and platforms for containerized applications are Docker, Kubernetes etc. Containerized applications are a powerful and versatile way to build and run applications that can be deployed and scaled across different environments. Buzinessware offers containerized cloud hosting solutions to host web/mobile applications. The solutions offered are fully managed, highly secure, reliable, costeffective, and have the flexibility to host on the cloud of the customer’s choice.
