The worldwide application container market was estimated to be worth 2.1 billion dollars in 2020. The market is anticipated to expand by over 33% annually until it reaches $5 billion by 2023. App containerization entails packaging software into standardized pieces for rapid and reliable deployment in various settings.

Explore The Future of DevOps: Automation Takes Over

Containers are a virtualization type of OS. A container can operate anything from a tiny software or microservice process to a bigger app. Hence, the hassle-free way to create microservices is by using containers.

You must be well-conversant of the term "containers" because of its rising growth in the digital market. A container includes every essential executable, including libraries, binary code, and configuration files.

But company ethics, processes, and methods play a vital role in software development. Here comes the most renowned approach to follow, which is DevOps practices. Simply put, DevOps and containers accompany each other.

Containers: Overview

Containers are a robust solution to get the software to operate reliably while moving from one computing ecosystem to another. It could be from a developer's PC to a testing framework, from a mounting environment into production. It could be from a physical machine to a virtual one in a public or private cloud.

The Requirement of Containers in DevOps

Consider a case where the software developers have jotted down the code in JAVA SE 7, and JAVA SE 10 is the production environment. This difference will lead to massive disasters, such as code-loading issues and non-functional features.

Are there ways to get rid of this compatibility issue?

Here comes the importance of containers in DevOps! So, how do containers improve DevOps processes? As an example of OS-level virtualization, containers are a collection of code, libraries, dependencies, and configuration files.

Without interfering with other containers or servers, each package may be tested, executed, and deployed in its environment and at its own pace. Therefore, changing computing ecosystems will never affect the performance of production and source code.

It should come as no surprise that by 2025, 85% of enterprises will have containerized their apps!

The Benefits of Containerization

Containerization provides full amenities to software developers. So, the benefits of containers in DevOps are the following:


The open-source Docker Engine has begun the industry norms for containers with hassle-free developer tools. This way of running containers follows a universal packaging strategy that works on Windows and Linux.

Here's the relationship between containers and DevOps. The container environment has transferred to engines controlled by the OCI. Software developers may keep using DevOps or Agile tools for the fastest software development.

Maximized production

Containers let rapid deployment, patching, or application scaling.

Consistent operation

DevOps Systems may run comparably in containers wherever they are deployed, according to DevOps teams.

Less overhead

Containers need fewer system resources than traditional machine ecosystems. It's because they don't include pictures from the OS.

Challenges of Containerization in DevOps

You must consider containerization's disadvantages when defining it. Here are various containerization drawbacks that hinder seamless integration within an organization:

  • It calls for a substantial amount of preparation.
  • Dependence and lack of support.
  • It is more difficult to keep tabs on containers than on virtual machines.
  • Although the common infrastructure is good for resource utilization, it might make businesses more susceptible to attack.

How to overcome containerization pitfalls in DevOps

Once you spot the difficulties in containerization, pay heed to these tips below:

  • Understand your project requirements.
  • Future-proof your containerization strategy.
  • Expertise.
  • Investing adequate time and effort.
  • Implement a wide array of tools.

Containerization vs DevOps

DevOps is a topic that is frequently brought up when talking about containers. You must comprehend why that is. DevOps is a collection of practices, an environment, and an ensemble of fundamental values, whereas containers are a technology.

The fact that containers are a technology that facilitates DevOps implementation is why you frequently see them combined. It's crucial to know that they can coexist independently. DevOps is not required for containers, and vice versa.

The Role of Containers in DevOps

DevOps is a directorial transformation modifying the way teams develop and deliver worth. Containers nowadays offer a seamless way to build software more effectively. The best practices for using containers in DevOps include a natural fit based on your company's priorities.

Wondering how containers improve DevOps processes? The benefits of containers in DevOps include more credibility and enhanced developer ecosystems. However, the role of containers in DevOps and the way they are revolutionizing software development, deployment, and testing are shown below:

Quicker delivery

Changes are made more manageable, faster to build, easier to test, and have fewer unexpected repercussions thanks to ongoing advancement, microservices structures, and an automatic DevOps pipeline.

DevOps professionals can concentrate on one piece of the puzzle at a time. They do it by breaking up an application into discrete containers, reducing their worries about the potential side effects of adjustments to one area.

Maximum reliability

The containerization in DevOps workflow lies in maximum reliability. Streamlined and reiterated processes ensure devoted and combined code every time. Everyone is now accountable for excellence through the societal shift of removing team barriers. The consistency of containers' operations improves the accuracy of tests.

Build containers into the DevOps workflow

Thinking of how to implement containers in DevOps?


Containers bring a maximum level of standardization technique to the development ecosystem. They define the required package versions by providing compatible ecosystems from a developer's laptop. It lowers the chance of errors creeping in because of environmental differences.


In contrast to direct installation to a VM or bare-metal server, where the target must be operational and ready to use, a container can be built once and saved for subsequent deployment. Because of this, builds are no longer dependent on the intended ecosystem and are only necessary when the container evolves. So, these are the differences between Containers and virtual machines (VMs).


By facilitating monitoring of the whole setup, rather than simply the code itself, containers expand the concept of an automated examination. Since the test context mirrors the real-world circumstances, this allows the distribution of software of higher standards.

Release and deploy

Because containers are repeatable, updating software in production necessitates creating and deploying a new container. Consequently, containers are frequently transient, which directly affects how businesses structure their systems and is advantageous to a microservices paradigm.


Containers reduce the danger of releasing fresh code or resources to a live application. There, a modification made in a single container is segregated. For instance, two administrations in distinct containers can rely on various JSON encoding/decoding libraries without worrying about how altering one will affect the other.

Common Use Cases of Containers

These are most common ways companies utilize containers include:

  • Refractor existing apps for containers.
  • Lift & Shift apps into modern cloud architectures.
  • Build new container-native apps.
  • Give DevOps support for ongoing integration & deployment.
  • Give enhanced support for microservices architectures.

Once you have created a container, it must never change. Every time you deploy a particular version of it, it will behave normally. But the question is: How do they add brand-new packages with new features and security fixes?

Upgrading a container implies creating a new version and replacing the older one asap. This consistency in the setting of a DevOps workflow indicates that experiments performed on containers in the CI/CD pipeline will react the same as, for instance if that container were in operation. As a result, tests are more trustworthy, and there is a lower risk that end users may encounter code problems or defects.
