Individually arrangedOpenStack and NFV Training
OpenStack is an open-source platform for building cloud computing environments. With this system, you can create a fully functional private or public cloud on your own infrastructure. The ecosystem allows you to manage all key cloud components, such as user access, cloud resource images, block, file, and object storage, virtualized networks, and network functions across different layers. Most importantly, OpenStack enables management of compute resources – from physical servers and popular virtual machines to container clusters and single containers. Additionally, it provides higher-level services such as databases, load balancers, telemetry, and DNS delivered in the u0022as a Serviceu0022 model.rn
What will you learn?
- Gain an in-depth understanding of OpenStack architecture.
- Learn to manage virtual resources such as VMs and storage volumes.
- Build virtual networks with routers and secure access to resources.
- Understand how virtualization of compute and networking is implemented at the OS level.
- Learn cloud monitoring principles and troubleshooting techniques.
- Secure cloud environments and infrastructure against unauthorized access.
