Modularizing applications with containerization using tools like Kubernetes and Docker

Use case


The traditional application model features software solutions that run directly on bare-metal servers or virtual machines. Businesses face challenges of getting their applications to run reliably when migrated from one computing environment to another—for example, transferring software from a developer’s device or a staging environment, or from a physical server in a data center to a virtual one in the cloud.

In most cases, the supporting software environment is not identical, and programming libraries keep changing, making it challenging to maintain scalability and portability in applications. As a result, DevOps engineers need to ramp up on multiple configurations, skills, and tools. The overall efficiency of a VM is limited, especially during peak load conditions that lead to intensive demand for CPU and memory from a physical machine running numerous VMs.


Containerization makes it possible for businesses to get applications to run reliably when moved from one computing environment to another.
A container features an entire runtime environment that includes an application, libraries, binaries, dependencies, and configuration files that the application needs to run reliably. 
Container management systems like Kubernetes provide automated mechanisms for deploying, maintaining, and scaling containerized applications. The tool groups containers that form an application into logical units for efficient discovery and management, allowing businesses to scale without increasing the Ops team.
Docker, on the other hand, offers an integrated, tested, and certified platform for developing, shipping, and running applications within containers. Additionally, Docker provides the Docker Hub framework to enhance rapid application development and deployment.


  • Scalable and cost-efficient - Modularizing applications with containerization abstracts away differences in underlying infrastructure and OS distributions. Containers have a small footprint and high portability, allowing businesses to scale and lower costs by hosting several of them in a single server. Containerization increases computing capabilities from 10 to 100 times that of legacy VM environments. 
  • Apps start instantaneously - Besides, users can start containerized applications almost instantly since they do not need the extra load of a hypervisor. Still, they run directly in the host machine’s kernel.
  • Less configuration - A Docker environment looks the same across multiple OS distributions and underlying infrastructure. This capability means that developers worry less about configurations variables while working with containerized applications. Containerizing applications allows businesses to run cloud-native applications on both virtual and physical infrastructure. 
  • Saves computing resources - Individual modules or microservices in containerized applications are instantiated only when needed, freeing up host resources.
  • Advanced modularity - Containerization allows for advanced modularity in applications. Instead of running an entire sophisticated software in one container, developers can split the application into modules based on the microservice concept. Businesses can make changes to a module without affecting the entire applications.
  • Enhanced DevOps strategy - Containerization enhances cloud-native development and deployment since it allows developers to focus more on application development roles without worrying about infrastructure provisioning and management. Docker and Kubernetes tools have become part of DevOps toolchains that would enable developers to focus on designing and building apps without worrying about provisioning and managing the underlying infrastructure.
  • Automated rollouts and rollbacks - Kubernetes allows developers to make continuous roll out changes to applications or configurations while examining the services to ensure that the modifications will not affect instances.
