With Containerization, Get ahead in your software development career

Containers are now an integral part of software development and have quickly become a crucial component of infrastructure management. Containers can help organizations increase the efficiency and agility of their IT infrastructure, while also reducing risks and costs associated with traditional virtualization techniques.

Here’s a brief overview of containerization and how it can help your organization. Also, learn how to use containers in your development environment.

What’s Containerization?

Containerization refers to the process of putting together an application and all its dependencies in one package. These containers are known as “containers” and can be easily moved without affecting their functionality. Because they contain only what is necessary to run an application, containers are lighter than virtual machines (VMs).

Containers can also isolate processes within them so that any container that crashes or becomes compromised won’t impact other containers on the host machine. This makes them very secure from outside threats like hackers looking to access your data through your containerized apps.

Containers are very safe from hackers trying to gain access to your data via containerized apps. Providers like JFrog or Canonical provide container management platforms that enable you to create and deploy containers.

The advantages of containerization

Containers are safer than virtual machines. Containerized environments allow applications to be run in their sandboxes. These contain all dependencies that are required for the application to run. There is no OS that’s specific to the application and therefore no risk of infection.

Containerization makes it easy to create secure containerized apps. You can use tools such as Kubernetes or Docker without needing to install any additional programs or learn any new ones.

Containers are quicker and easier to manage than virtual machines (VMs). VMs need hypervisors like VMware ESXi and KVM to be used on bare metal servers. However, containers don’t require hypervisors as each container has its own operating system instance. With containers, however, each app requires only Linux kernel features. VMs do not require additional layers of software to run on top of their host OS. This makes them smaller than VMs as they don’t take up much space on your server.

How do you get started with containerization?

Understanding containerization and its principles are the first steps. Containers are a way to package up software or applications so they can be moved easily from one machine to the next without installing any additional software. This is similar to the way you would take your clothes out of the closet and fold them neatly in a suitcase.

 Once your coat is on, you can walk out the door and head somewhere else. But instead of clothes and shoes being carried inside the suitcase (or “container”) we are talking about applications: WordPress and MySQL databases.

Containerization platforms allow you to build containers for different purposes. These platforms make it simple to create containers that can run web servers and host websites, run applications such as Elasticsearch clusters, optimize images, run image processing tasks such as resizing photos or optimizing photographs; and run applications that require high-performance computing resources like those used in Hadoop MapReduce jobs.

Optimizing containers for production and development environments

Next, optimize your containers for each environment. To test changes and make sure they work, you can use a local environment for development. A staging environment can be used as an intermediate step between production and production. Before committing the changes to your live site, you can ask for feedback.

What does container orchestration software fit in this?

Container orchestration tools provide a layer between the application and infrastructure. These tools allow you to deploy containers, scale them, update them, and manage them reliably. Kubernetes and Mesos are two examples of such tools.

Here are some examples of container orchestration tools

  • Docker Swarm
  • Kubernetes (Apache Mesos)


Software developers can have a rewarding career. While it is possible to make a living and work at your own pace in this industry, there are still many things you must do. Containers are great because it makes it simple for developers like you to build their apps from scratch or reuse existing ones for building blocks.
