In Detail
OpenVZ (Open Virtuozzo) is an OS-level virtualization technology based on the Linux kernel and OS written in C. It creates multiple secure and isolated Linux containers on a single physical server, enabling better server utilization and ensuring that applications do not conflict. OpenVZ is the only highly scalable virtualization technology with near-zero overhead, strong isolation, and rapid customer provisioning that's ready for production use right now.
Starting with the very basics of OpenVZ, you will learn to configure templates, create containers, administer your server infrastructure, and utilize the OpenVZ Web Panel.
Packed with practical examples and precise instructions, this book helps you to set up and configure OpenVZ. An easy-to-follow guide that will help you with real-world container administration tasks. The book has a natural flow from one topic to another and will ensure that you gain expertise in the effective implementation of OpenVZ.
