A container is a unit of software that packages code and its dependencies, so the application runs quickly and reliably across computing environments. The use of containers can virtualize operating systems to run anywhere, from on-premise to cloud, or even personal laptops. Inside a container are all the necessary executables, binary code, libraries, and configuration files.
Using containers to address challenges around the deployment of application code
Development teams are under a significant amount of pressure to become more agile and deliver new features to the lines of business more quickly. One area that is under constant strain is the deployment of new or improved application code with the frequency and speed required by digital transformations. To meet these requirements, containerization has become increasingly popular as applications running in containers can be easily deployed to a variety of operating systems and hardware platforms.
Containerization is one of the latest developments in the evolution of cloud computing. Through capabilities such as continuous integration and delivery, many organizations, are considering containers to improve application life-cycle management.
Containers are now the foundation of the cloud. As more and more organizations are moving to the cloud, a private cloud platform is preferred since it ensures the necessary protection and control while enabling the employment of a variety of cloud services. With the use of containers, organizations are able to execute their applications on the cloud and achieve the three key requirements – 1) Modernize existing applications 2) Create new cloud-native enterprise applications 3) Open data center to work with cloud services.
