infrastructure continue to choose cloud-based technologies to power their digital transformation. As they move away from their legacy environments to hybrid, multi-cloud stacks, enterprises are creating IT operations with containers and Kubernetes. The recent Forrester Wave report1 stated that these cloud native technologies are quickly becoming the preferred way for global organizations to build and containerized applications in production by 2022. Confidence of this prediction demonstrated the value of cloud native technologies for developers, who will always look for solutions to help them build applications

md 11/30/2018 18 / 24 Tracking down what actions were performed by users in Rancher can provide insight during post mortems, and if monitored proactively can be used to quickly detect malicious actions Node drivers are used to provision compute nodes in various cloud providers and local IaaS infrastructure. For convenience, popular cloud providers are enabled by default. If the organization does not
