В кластер входят документы об архитектуре и развертывании комплексных частных облачных платформ, но не входят узкотехнические инструкции по настройке отдельных компонентов хранения данных.
Общие признаки: частные облака, OpenStack, распределенное хранилище Ceph, отказоустойчивость систем, инструменты open-source
Группа выше: Собственные и децентрализованные облака
Смысл: The main idea is to provide a practical, technical implementation guide for creating a professional-grade, high-availability private cloud using open-source tools, emphasizing the synergy between distributed storage (Ceph), replicated databases (Galera), and cluster management (Pacemaker) under OpenNebula.
A detailed technical tutorial on deploying a fault-tolerant private cloud using OpenNebula, Ceph for tiered storage, MariaDB Galera for DB replication, and Pacemaker for high availability on CentOS 7.
Смысл: The main idea is that for most users, building a private cloud using OpenStack on cheap commodity hardware (like Hetzner) is a viable and drastically more cost-effective alternative to expensive public cloud providers like Amazon EC2, provided the system is architected for fault tolerance.
Using OpenStack on inexpensive Hetzner hardware can reduce cloud computing costs by 10-17 times compared to Amazon EC2 for users who can handle manual setup.
Смысл: The main idea is to introduce Ceph as a powerful, flexible, and decentralized storage solution that solves the problem of scalability and reliability in cloud environments by using a software-defined approach and the CRUSH algorithm.
An educational guide explaining the architecture, components, and data distribution mechanisms of the Ceph distributed storage system.
Смысл: The main idea is that OpenStack's pursuit of a simple end-user experience has resulted in an overly complex, unstable, and bloated backend that is difficult to maintain and upgrade, making it a poor choice for small to medium-sized deployments.
The author warns against using vanilla OpenStack, describing it as an overly complex, unstable, and bloated system that creates more maintenance burdens than it solves.
