Why Docker Containers are important for telcos
Globally, it is estimated that there would be 23 billion connected devices installed by the end of 2018 and it is projected to reach 75 billion by 2025. Increasing use of smart devices and growing demand for connectivity services are driving digital transformation impacting all facets of technology.
Digital transformation has influenced software industry and is driving innovation. Among the recent innovations, Docker Container is considered as one of the promising developments. According to Forrester, 10 percent of the enterprises use Containers and one-third of the enterprises are testing them. Container technology has been around for a while, but Docker’s innovative approach to containers have pushed this approach to the forefront.
Docker is a platform which allows software piece contained in separate containers run simultaneously. It works independently on different operating systems. Docker provides the ability to package and run an application in a loosely isolated environment called a Container. Separate Containers are required to run a part of the software.
When compared to Virtual Machines, where the entire operating system is boarded, Containers only host libraries and settings required for the software to work. This makes containers independent of background allowing the functioning of multiple containers simultaneously on a given host. Docker Container enables secure and faster delivery of new features, detaches application from infrastructure and allows developers to focus on hassle-free coding.
Containers & Docker - essentially create a package around a piece of software that includes everything it needs to run. The software can then run the same way in different operating environments. That fits neatly into the telecom operators' movement from an infrastructure focus toward an application one in response to customer demand.

Key features of Docker Containers
- Lightweight: Consumes less bandwidth and functions faster as it shares machine's operating system. Reuses components from the preceding layers, which makes it lightweight.
- Independent: Compatible with all operating systems
- Easy deployment, testing and shipment: Allows continuous integration and deployment. The minimal runtime reduces the size of software resulting in faster deployment.
- Flexibility: Isolating software pieces allows smooth running of different software on the same infrastructure.
- Security: Owing to its own network interface, file system and memory, the application running in the container can be secluded and secured from other activities in a host computer.
- Version change: Version updates can be centrally monitored and updated with minimum downtime. Successive versions of a container can also be tracked, inspected or rolled back to previous versions.
- Sharing: Docker Containers are shared with repositories located at a remote location.
- Minimum RAM usage: Small image size of Docker Container enables swift movement and allows multi-application functionality on the same hardware.
