Word of the Day: application containerization

Word of the Day: Daily updates on the latest technology terms

Word of the Day Daily updates on the latest technology terms | December 23, 2019 application containerization Application containerization is an approach to virtualization that allows multiple, isolated applications or services to run on a single host and share the same operating system (OS) kernel.   Proponents of containerization point to gains in efficiency for memory, CPU and storage, especially when compared to traditional virtualization or physical application hosting. Because there are no guest OS environment variables or library dependencies to manage, version control takes place at the image level and replaces configuration management at the system level.  Containerization also offers security benefits because of the increased isolation of application packages and the use of specialized, lightweight OSes to run them. Policy can be used to dictate privilege levels for containers and make deployments even more secure. Continue reading...

They can implement several commands to help them do so successfully. Container backup grows, following container adoption Although demand for container backup remains low, vendors anticipate growth in this area. Containers have shifted from being lightweight throwaways to persistent mini-VMs. How container adoption affects container security Scalability and efficiency make container adoption an attractive option for enterprises today. Learn how containerization has evolved and grown since the release of Docker 1.0 five years ago.
