Containerization is a powerful tool for software development that has gained widespread popularity in recent years. Essentially, containerization is a way to package an application, along with its dependencies, into a single container that can run consistently across different environments. By using containers, developers can create portable, scalable, and isolated applications that can be easily deployed and managed. It’s a game changer for software development as it makes it more efficient, reliable and cost-effective. In this post, we will explore the basics of containerization, its key concepts and benefits, and how it can revolutionize software development.

Now that we have a better understanding of what containerization is, let’s delve deeper into how it works in the next section.

What is a container?

When it comes to running an application, there are a couple of ways to do it. You could use a virtual machine, which is like creating a separate computer within your computer. This approach allows you to run multiple operating systems on the same computer, but it can be quite resource-intensive.

Another way is to use containers, which allow you to package an application and its dependencies together, so it can run consistently on any environment.

What’s the difference?

While both technologies allow you to run software in a virtual environment, containers are the lighter and more efficient option. They allow you to run multiple applications in the same environment without having to create multiple virtual machines, making them the perfect partner for a streamlined software development process. And with the help of container orchestration tools, you can easily spin up and scale applications like a pro, ensuring your applications are always running smoothly, no matter how many users you have. With the help of container orchestration tools, you can easily manage and scale your applications in response to changing user demands.

Another way containers differ from virtual machines is in how they use their resources. Virtual machines are like creating a separate computer within your computer. They let you run different types of operating systems on the same machine, but they use up a lot of resources. And for each virtual machine, you need to install a separate operating system. Containers are different, as they don’t need their own operating system, so they start up faster and use fewer resources. Plus, they keep different parts of the application separate at a more detailed level than virtual machines.

Using containerization makes it easier to package and run your applications. It’s way more efficient and effective than using virtual machines, plus you get extra benefits like improved portability, scalability, and isolation when compared to virtual machines.

Popular Container Apps

There are a few different container technologies out there, but some of the most commonly used are Docker, Kubernetes, and Apache Mesos. Let’s take a look at each one in more detail.


Docker is a popular containerization platform that makes it easy to create, deploy, and run applications in containers. It provides a command-line interface that simplifies the process of working with containers, making it easy for developers to create and manage containers for their applications. Docker also provides an ecosystem of tools, such as the Docker Hub, which is a centralized repository for storing and sharing container images.


Kubernetes is an open-source container orchestration system that automates the deployment, scaling, and management of containerized applications. It was originally developed by Google, and has since become one of the most popular container orchestration platforms. Kubernetes provides a powerful set of features for scaling and managing containerized applications, making it a popular choice for running large-scale, production-grade applications. Our team has a deep understanding of this technology and can assist in effectively utilizing it to meet the needs of your organization. We can containerize your applications, and even migrate them to the cloud.

Apache Mesos

Apache Mesos is another open-source container orchestration system, like Kubernetes. It aims to simplify the scaling and management of applications. Mesos provides a simple and powerful API for scheduling and managing containers. It’s often used in combination with other container orchestration and scheduling frameworks, such as Marathon, to manage large-scale container deployments.

Benefits of Containerization

Containerization offers numerous advantages for software development and deployment, including increased portability, isolation, scalability and efficiency. These benefits enable organizations to package and distribute applications more easily, run them in different environments and handle changing user demands. Let’s look at each one of these benefits more closely and see how they can be applied in practice.


Containers provide a consistent way to package and distribute applications, making it easy to move them between different environments, such as from development to production. This helps organizations to more easily test and deploy their applications, reducing the time and effort required to make them production-ready. Containers also make it easier to run applications in different environments, whether it’s on-premise, in a public or private cloud.


Containers provide a level of isolation between different parts of an application, which helps to prevent conflicts and makes it easier to manage dependencies. This makes it more convenient for developers to create and test applications, and for operations teams to deploy and manage them. Containers also allow multiple applications to run on the same host without interfering with one another, which can help you make the most of your resources and cut down on expenses.


Containers orchestration tools like Kubernetes make it easy to scale applications up or down, depending on user demand. This helps ensure that applications are always running smoothly. It also allows you to be more responsive to changing business needs and handle high loads during peak usage times. Container orchestration makes it easy to deploy, scale and manage containerized applications, which helps to minimize the effort and cost associated with scaling applications.


Containerization can increase efficiency in the software development process in a few ways. For example, by packaging an application and its dependencies together in a container, developers can ensure that the application will run consistently across different environments. This eliminates the need for developers to spend time troubleshooting environmental issues and allows them to focus on writing code. Additionally, using tools like Kubernetes can streamline the development and deployment process, reducing the time and effort required to get applications to a production-ready state.


As we’ve seen above, containerization is a powerful technology. To reiterate, there are many reasons to use containers. These include increased:

  • portability
  • isolation
  • scalability
  • efficiency

These benefits make it easier to test, deploy, and scale applications. All while reducing costs, and increasing resource utilization.

With all these benefits in mind, it’s clear that containerization can bring significant advantages to any organization. And that’s where Electric Pipelines comes in.
