Like containers used for transporting goods, IT containers are designed to store objects so that they can be transported more easily. The containerization of applications has many virtues and allows in particular to :
- Virtualize the hardware resources (file systems, processor, memory, network, …) essential for the execution of an application.
- Store all application dependencies: files, libraries, etc.
Guarantee the integrity of the content
Containers enable the safe and efficient transport of applications and their dependencies to various operating systems. They accomplish this by providing isolation for the content, ensuring its integrity throughout the process. This robust isolation not only protects the content but also improves system security.
The container connects to the kernel to move virtual applications between operating systems and enable communication between hardware and software components. This connection is crucial for smooth operation in the new environment.
In addition to the benefits of portability and security, containers also allow for more efficient resource utilization. Because they package all necessary components within a single container, there is no need to duplicate resources across different applications. This can lead to significant cost savings and improved performance.
IT infrastructure automation
Containerization has numerous technical benefits that can streamline application configuration and administration, speed up development and production cycles, and facilitate automation in IT infrastructures. Some of the key advantages include:
- Minimizing complexity: Containerization simplifies the process of setting up and managing applications by packaging all necessary components into a single container. This eliminates the need to worry about conflicting dependencies and reduces the overall complexity of the system.
- Accelerating cycles: Containers make it faster and easier to move applications between different environments, allowing for quicker development and production cycles.
- Facilitating automation: The portability and flexibility of containers make them an excellent tool for automating IT infrastructures. They can be easily moved between different environments, making it easier to scale and manage applications.
Reduction of the "time to market"
Containerization is a significant technological advancement that greatly improves the development and delivery process for applications. It allows for a faster turnaround time between the conception of an idea and its implementation in an application, known as “time to market.” This is what allows tech startups and giants to continuously offer new features to their users.
Thanks to containerization, the speed and efficiency of releasing new features and updates is significantly increased. This is a major advantage in today’s fast-paced tech industry, where staying competitive requires a constant stream of innovative features and updates.
More reliable systems
As time goes by, the containerization tools that are gradually maturing are also becoming more reliable.
The possibility of fraudulently breaking into a container to access the machine’s resources is being eliminated.
And when orchestration security is 100% guaranteed, it’s a safe bet that groups of machines will be able to host containers from completely heterogeneous systems. This technical opportunity will then allow any application to use resources that do not belong to it.
Docker, a pioneer in the containerization market, introduced its concept of application containers in 2013 and developed open source software for managing them. As part of this effort, Docker created a format for creating and running container images that was quickly adopted by the Open Container Initiative (OCI) as a standard.
Since its inception, Docker has played a leading role in the development and adoption of containerization technology. The company’s containerization platform, known as Docker Engine, allows developers to easily package and deploy applications in containers, making it easier to build, test, and deploy applications quickly and consistently.
In recent years, Docker has faced increasing competition from other containerization platforms, such as Kubernetes. Despite this, Docker remains a widely used and influential player in the containerization market, with a strong reputation for reliability and ease of use.
