Layer 2 networks Layer 3 subnets IP address management DHCP based Router / gateway / NAT Port (Security groups, Floating IP) Layer 4-7 Services - Load balancing, VPN, Firewall 6. Networking in OpenStack Horizon 7. What is Heat?Heat provides amechanism fororchestratingOpenStackresources throughthe use of modulartemplates. 8. Heat Architecture 9. Heat Topology View 10. What is TOSCA?TOSCA defines theinteroperable descriptionof applications; includingtheir components,relationships,dependencies,requirements, andcapabilities. 11. TOSCA in a NutshellMapping of application logicthrough plans (workflows),policies, relationships,actions 12. TOSCA State of the Union Top four cloud open standard (Forrester) 5000+ participants 65+ countries TOSCA Parser Integrated into theHeat ProjectThe focusof this session 13.
