DevOps teams have embraced Docker container technology because it boosts speed, agility, and flexibility in app development and delivery. But it also creates security and compliance challenges.
“Containers are revolutionizing the IT landscape,” Hari Srinivasan, a Qualys Director of Product Management, said during QSC18 Virtual Edition. As the next big thing in IT, containers are seeing tremendous growth in adoption.
“Containers are lightweight, efficient, portable, and they boot faster, making it highly efficient and easy for developers to deploy their applications,” he said during his presentation “Securing Containers — From Build to Deployments.”
Containers are lighter than virtual machines because they can be spun up without provisioning a guest operating system for each one. For that reason, they also churn much more frequently.
With containers, applications can be smaller, focused on one or a few capabilities, and more portable, because they can be easily distributed across an IT environment, he said. That’s why containers have helped popularize microservices, a new architecture where applications are structured as independent, small, modular services.
