Advantages and Disadvantages of Containerization Technology

Advantages 

1. Security. Containerization technology address companies’ top main concern: security. By essentially separating personal ‘apps’ and data from business apps and data on employees’ portable devices, it obviates the possibility of sensitive data leaking from one to the other.

2. Resource consumption. Containerization brings in the use of single instance of operating system with no hardware virtualization. There is only a small application and operating environment in a container.

3. Cost saving. The cost of operating and start of virtual machine is much higher than container and it lowers the transport costs as well.

4. Efficiency: First, it supports resource sharing. In addition, it removes the hassle of code conflicts, application conflicts, multiple restricts and access and so on. Application with all of its dependencies -- code, libraries, configurations, system tool is into a wrapper file system. Because everything is there, it is easy to make changes and updates within a container without impacting adjacent containers. Finally, transitions between development, testing, and production environments are much smoother.

Disadvantages 

1.Theft and losses. Containers move through server memory and there are questions about whether communications might inadvertently be exposed to other containers. Therefore, containers may also bring security issues.

2.Complex installation. When the container applications are installed, changes have to be made on the phone and the terminal’s ROM. Moreover, the containers have to have MAM or mobile device management (MDM) systems to make this approach effective.

3.Reduce battery life. The containers use a lot of energy and processing power, thus reducing battery life and significantly impacting the end user’s experience.

4.Immature. This technology is not mature. The use and management of application containers is not well understood by the broader ops, InfoSec, dev and auditors community yet. This makes the process of marketing for the application becoming harder.
