Containers are everywhere, and they’ve radically changed the IT landscape. What do you need to know about them?
Containerization has radically changed the IT landscape because of the significant value and wide array of benefits it brings to business. Nearly any recent business innovation has containerization as a contributing factor, if not the central element.
In modern application architectures, the ability to deliver changes quickly to the production environment gives you an edge over your competitors. Containers deliver speed by using a microservices architecture that helps development teams create functionality, fail small, and recover faster. Containerization also enables applications to start faster and automatically scale cloud resources on demand. Furthermore, DevOps maximizes containerization’s benefits by enabling the flexibility, portability, and efficiency required to go to market early.
While speed, agility, and flexibility are the main promises of containerization using DevOps, security is a critical factor. This led to the rise of DevSecOps, which incorporates security into application development from the start and throughout the lifecycle of a containerized application. By default, containerization massively improves security because it isolates the application from the host and other containerized applications.
