A CONTINUOUS OFFERING FROM PRIVATETO PUBLIC CLOUD
WINDOWS AZUREVIRTUAL MACHINES * http://bit.ly/azurevmsupport
COMMON ISSUES VM Disappears or was deleted (MSND /Free Trial) Blob storage occupied (VHD not deleted) Temporary Disk (how temporary is it?) What disk size should I chose?
INTERNET CONNECTIVITY Outside-In
Virtual Machine (IaaS) Local IP (DIP) LB VIP Windows Azure Cloud Service (foo.cloudapp.net) INTERNET NETWORKING PICTURE
OUTSIDE-IN CONNECTIVITY Endpoint Definition Windows Firewall Rules Corporate Firewalls PING times out
VNET SCENARIOS Define IP Address space forVMs IaaS Interconnectivity Site-to-Site Point-to-Site IaaS-to-PaaS and vice-versa
VNET Address Spaces 10.0.0.0 172.16.0.0 192.168.0.0 Sub Nets Gateway Sub-Net
ADDRESS ALLOCATION SECRETS Always and only by DHCP The first host gets the 4th IP Address i.e. 192.168.0.4 Automatic cross-sub-net connectivity Internal IP Address Reservation!
VNET CROSS-PREMISES Site-to-Site Point-to-Site Express Route
VNET LIMITATIONS No Cross-Data-Center Connections No site-to-multiple-sites Connections
NAME RESOLUTION SCENARIOS When not inVNet PaaS only (Web/Worker Roles) IaaS only (Virtual Machines) When inVnet Cloud only Cloud + Site-to- SiteVPN
DNS SERVER ON IAAS
DNS SERVER SECRETS Just for the DNS server machine, set DNS to 127.0.0.1 when deploying! Place the DNS Server on its own subnet Remember the full format of FQDN http://bit.ly/fqdn Reserve “Static IP Address” for theVM http://bit.ly/azurestaticip
IP ADDRESS ASSIGNMENT SECRETS IP Address predictability and reservations Sub-net isolation Address Space Isolation
AD/DC ON IAAS Highway to Clouds
