Baidu Cloud Compute (BCC) vs OpenNebula

Baidu Cloud Compute (BCC) creates and manages elastically scalable cloud server instances. Instance families include general-purpose, compute-optimized, storage-optimized, GPU, and FPGA options, with public, marketplace, service-integration, or custom images. Users can adjust instances and bandwidth, scale resources, and connect private data centers in a hybrid cloud. APIs cover creating, stopping, querying, reinstalling, and releasing instances; remote access uses Client, SmartTerm, or VNC. Security features include multi-layer DDoS protection, failover completed in seconds, automatic snapshots, an instance-level virtual firewall, and monitoring alerts. The product page states 99.9999999% data durability. Postpaid use is billed per minute, rounding partial minutes up; prepaid terms run one to nine months or one to three years, while reserved instances use one- or three-year commitments. BCC supports web, API, Linux, and Windows, and creating an instance requires real-name certification.
