Kubernetes Resources Management - QoS, Quota, and LimitRange
March 1, 2020
/By Brandon Tsai
The applications were typically run standalone in a VM and use all of the resources. The operators and developers need to choose the size of the VM for running the application.

/By Peter Schlesinger
A good level of “built in” security is an inherent benefit of using container technology. This doesn’t mean that relying on a default installation of these components will provide an adequate level of security in itself or that you can absolve yourself from thinking about security.[...]
