#OTC #cloud #devops #IAAS #PAAS #DBAAS #BDAAS #container-services
The purpose of the OTC Tool is to manage OTC cloud environments via the command line similar in a way to AWS CLI. OTC CLI provides a common interface to operation and DEVOPS teams to manage their cloud services. On top of that, the language implementations (Python at the moment) are secure and relatively fast.
