Apache CloudStack vs Baidu Cloud Compute (BCC)

Apache CloudStack is free, open-source software for deploying and managing networks of virtual machines as a highly available, scalable IaaS cloud platform. Organizations can use it to build public, private, or hybrid clouds. Its features include compute orchestration, network services, account management, resource accounting, a web interface, and an open API. Operators can manage clouds through a web UI, command-line tools, or REST API, with optional AWS EC2- and S3-compatible APIs. Supported hypervisors include XenServer or XCP, KVM, Hyper-V, and VMware ESXi with vSphere. Storage options include iSCSI, NFS, Ceph RBD with KVM, volume encryption, snapshots, and storage tiering. Authentication options include OAuth2 single sign-on, two-factor authentication, TOTP, SAML, and LDAP. The project says CloudStack can manage tens of thousands of physical servers across geographically distributed data centers. Long Term Support releases receive bug and security fixes for 18 months after the main release. Operators remain responsible for protections such as monitoring, host security, and defenses against DoS and brute-force attacks.

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.
