1.1. Overview

SmartApps-CLOUD is an OpenNebula Multi-Node public and private cloud owned by SmartApps. There are private services running inside the cloud, only available for the administration group OPENNEBULA_ADMIN_ACCESS_DL and oneadmin. SmartApps also wants to deliver public cloud services on current cloud and also sell VDCs for clients with specific performance tiers.

1.2. Authentication

• SmartApps-CLOUD use default core authentication for oneadmin user and LDAP auth, for SmartApps administration groups and customers.
• SmartApps administration group use a different LDAP server from the customers, and is the only LDAP group with full administration priviledges in the cloud.
• Each LDAP group for customers needs to be manually created on the opennebula cli and mapped with the LDAP group DN.
• Customers with group admin priviledges will belong to an LDAP group created just for this, for mapping group admin priviledges.

1.3. Cloud resources

• Clusters:
  • default: 0 (not used)
  • KVM: 100
• Hosts:
  • SmartApps-CLOUD-node1-kvm: 0
  • SmartApps-CLOUD-node2-kvm: 1
  • SmartApps-CLOUD-node3-kvm: 2
  • SmartApps-CLOUD-node4-kvm: 3 (with faster CPU)
  • SmartApps-CLOUD-node5-kvm: 4 (with faster CPU)
  • SmartApps-CLOUD-node6-kvm: 5 (with faster CPU)
• VNets:
  • Client Network: 0 (default VNet with access to internet)
  • IPMI_NET: 2
  • SmartApps_MGM_NET: 3
  • MGM_NET: 4
  • SmartApps_SRV_NET: 5
  • REAL_PUBLIC_NET: 6
• Datastores:
  • MSA2062_LUN01-SYS-SSD: 0
  • MSA2062_LUN01-IMG-SSD: 1
  • MSA2062_LUN02-SYS-HDD: 100
  • MSA2062_LUN02-IMG-HDD: 101

1.4. VDC per customer

• Based on performance tiers:
  • All cloud resources available: VDC default.
  • Faster CPUs and SSD storage backend: VDC <customer_name1>
  • Faster CPUs and HDD storage backend: VDC <customer_name2>
  • Faster CPUs and Ceph storage backend: VDC <customer_name3>
  • Normal CPUs and HDD storage backend: VDC <customer_name4>.
  • (...) and many more performance tiers could be created based on customers needs.
