Containerization in software development improves the quality of work as well as its speed and efficiency. The goal of containerization is to help developers create code in bulk alongside its required data to run for quick transfer. This entire method makes automated testing simpler to do in comparison to the virtualization method, making it a simpler way to continue with a developer’s work and maintenance. But what are the necessities of containerization? What are its benefits and challenges? And how do you know if you’re applying it correctly? That’s where we come in. Learn more about this reliable software code and its benefits for your future projects below. What is Containerization? Before we go all about the functions and details, we should first understand the meaning of containerization. In simpler terms, containerization refers to a packaging method of software code with only its dependencies and operating systems required to run.  The packaging containing these software codes is called a container and should run within any infrastructure. Oftentimes containerization is assisted by programs that function as containerization orchestration, which helps in the entire lifecycle of the applications under containers.  Software developers that utilise the agile method or optimises DevOps workflows usually utilise containerization because of its efficiency and speed in its lifecycle process. How Does Containerization Work? So how does containerization work? It’s a method of organisation that speeds up the deployment and creation of applications. The goal is to efficiently create programs with more security in comparison to traditional methods.  Traditional methods would utilise a specific platform to write their code before transferring it to the new location. As a result, errors often occur during the transition. Like an employee creating the perfect document in the notes app of their laptop but when transferring it to Microsoft Word, it becomes jumbly and messy. Containerization erases this possible issue by bundling the codes and their required files into a singular container. This makes it easier to transfer between clouds, platforms, or other areas without worrying about any damages from coding it previously. Aside from containerization, there’s also virtualization, which is often mixed up with each other. Below are some key differences between the two methods. Containerization VS Virtualization Before containerization there was virtualization.. While both methods exist and have a similar purpose they have differences that create a clear distance between each other’s performance. Isolation Process Virtualization prefers to isolate OS (operating system) and VM (virtual machine) together. Meanwhile, containerization isolates the host operating system and its containers from one another.  Multiple Operating Systems VS One Operating System Virtualization can host multiple complete operating systems. Meanwhile, containerization runs on every single container in one operating system. Multi-access Support Containerization can only be used on the host operating system. That means if the program was created on Windows, it can only be used on Windows. However, virtualization can be accessed on a wide range of operating systems as long as it’s used on the same server or machine. Requirements for Deployment Deployment is also different when it comes to virtualization. Unlike containerization, which requires different apps to deploy either an individual or multiple containers, virtualization has its VM that acts as its hypervisor for deployment. Virtual Storage Virtualization uses virtual hard disks (VHD) for each VM. Meanwhile, containerization uses local hard disks per node. Both utilise server message blocks (SMBs) for sharing different virtual machines or nodes respectively.  Balancing Loads Containerization maximises resources by orchestrating with tools and stopping containers or stopping them when needed. Unfortunately, that means there are limited available resources. On the other hand, virtualization uses failover clusters to run virtual machines by balancing the load for support.  Virtualized Networking The last difference between virtualization and containerization is the way they utilise virtual network adaptors. Virtualization uses VNA for networking by handling it with a network interface card. Containerization splits the VNA for lightweight network virtualization. 5 Benefits of Containerization There are multiple benefits to using containerization. However, these five benefits are the ones deemed beneficial. Security Enhancement The most obvious benefit when using containerization is a cyber security enhancement. Since you isolate the containers it makes security easier to monitor and difficult to breach. It’s even possible to add more layers of isolation for risk mitigation when you’re utilising shared kernel vulnerabilities. Portability and Compatibility Containers are highly known for their portability for easy deployment and migration. This is because containers have standardized steps regulated by the OCI (open container initiative) for seamless compatibility and transportation.  Because of this, containerization in cloud computing is possible. Thanks to containerization’s method of virtualization,  any platform can run these containers as long as it supports its technology.  Scalability Scalability is an important part of a software developer’s code. Changes are constant when talking about programs and applications. Just like with any other code, it’s natural to have bugs and errors when scaling. The great part about containerization is that it can utilise autoscaling thanks to containerization orchestration tools like Kubernetes. Its advancement simplifies scalability and even fixes bugs automatically. This assures efficiency in your programs and applications when scaling. Cost Reduction Everything has a price. Fortunately, containerization isn’t as pricey as you would expect it to be. It could even reduce your costs. Containers are suitable for large-scale deployments thanks to their ability to optimise resources. It’s not as heavy as manually transferring the code piece-by-piece which lowers the costs of building your code infrastructure.  Consistency  Last but certainly not least is its consistency. Containerization is consistent throughout your software’s entire development process. This helps ensure that the code works throughout all machines compared to other methods. Support containerization’s consistency by adding development operations (DevOps) to make it more agile and reliable with each step of the process. 5 Challenges and Limitations Software development always has its challenges. Naturally, so does containerization. Here are five issues you will likely face if you utilise containerization in your software development process.
