What is OpenStack? Oh – it's not the same as OpenShift? So what is OpenStack? If these questions are on your mind and you want to learn more about why OpenStack is used by many large organizations to build their own private cloud offering than listen to this 101 talk with Dirk Wallerstorfer (@wall_dirk). We learn about the different OpenStack core controller services (Cinder, Horizon, Keystone, Neutron, Nova …) as well as the core cloud services (Compute, Storage, Network, …) it provides to its users. Dirk also explains why and who is moving to OpenStack and what the challenges and use cases are when it comes to monitoring OpenStack environments – both for an OpenStack Operator as well as for the Application Owners that run their apps on OpenStack.
