\n\n1. vCloud Extender Overview<\/h3>\n
Display of the migration status and connection status to the Virtual Datacenter<\/p>\n<\/div>\n<\/li>\n
![\"Festlegen](\"https:\/\/serverbase.ch\/wp-content\/uploads\/2019\/02\/vcloud-extender-provider-clouds-1600x682.jpg\")
\n\n2. Connection to Virtual Datacenter<\/h3>\n
Configure the connection to the migration endpoint in Virtual Datacenter<\/p>\n<\/div>\n<\/li>\n
![\"Konfiguration](\"https:\/\/serverbase.ch\/wp-content\/uploads\/2019\/02\/vcloud-extender-dc-extension-1600x512.jpg\")
\n\n3. Layer-2 VPN network<\/h3>\n
Extension of the local network into the Virtual Datacenter via integrated Layer-2 VPN<\/p>\n<\/div>\n<\/li>\n
![\"Starten](\"https:\/\/serverbase.ch\/wp-content\/uploads\/2019\/02\/vcloud-extender-migration-assistant-1-1600x903.jpg\")
\n\n4. Selection of the migration type<\/h3>\n
Selection of the desired migration type for the migration job. Cold Migration requires that the VMs being migrated be shut down and Warm Migration be started.<\/p>\n<\/div>\n<\/li>\n
![\"Auswahl](\"https:\/\/serverbase.ch\/wp-content\/uploads\/2019\/02\/vcloud-extender-migration-assistant-2-1600x912.jpg\")
\n\n5. Selection of Source VMs<\/h3>\n
Transfer the VMs to be migrated from the on-premise environment to the migration job<\/p>\n<\/div>\n<\/li>\n
![\"Auswahl](\"https:\/\/serverbase.ch\/wp-content\/uploads\/2019\/02\/vcloud-extender-migration-assistant-3-1600x912.jpg\")
\n\n6. Set Virtual Datacenter as destination<\/h3>\n
Virtual Datacenter is set as the destination and the desired storage profile (SSD, HDD, or Archive Storage) and target network are selected. Thanks to the Layer-2 VPN, the IP configuration of the VMs to be migrated need not be adjusted.<\/p>\n<\/div>\n<\/li>\n
![\"Migration-Job](\"https:\/\/serverbase.ch\/wp-content\/uploads\/2019\/02\/vcloud-extender-migration-job-1600x511.jpg\")
\n\n7. Perform migration<\/h3>\n
When the wizard completes, the migration starts and the workload moves to the Virtual Datacenter. With the cutover, the local VM is stopped, a final delta synchronization is performed and the VM in the Virtual Datacenter is resumed within a few minutes.<\/p>\n<\/div>\n<\/li>\n<\/ul>\n
<\/a>
\n<\/a><\/p>\n<\/div>\nTransfer to productive operation<\/h2>\n
After the migration and starting of the VMs in the Virtual Datacenter, all operated services are available again. When accessing the Internet, the traffic arrives at the on-premises gateway and is redirected via the Layer 2 VPN to the VM in the Virtual Datacenter. This leads to a double burden of on-premise internet connection. The following simplified architecture shows the problem.<\/p>\n
![\"vCloud](\"https:\/\/serverbase.ch\/wp-content\/uploads\/2019\/02\/zugriff-nach-der-migration-1600x919.png\")
After the migration, the access from the Internet to server 2 via the on-premises network, because this is only possible via the Layer-2 VPN. The Extended LAN1 can not be connected directly to the Edge Gateway in the VDC, which creates a double load on the on-premises Internet connection with every access.<\/p><\/div>\n
Because the edge gateway in the VDC can not be directly connected to the extended LAN1, the dependency on the on-premises infrastructure persists, which is desirable in the fewest cases. To solve the problem, the migrated VMs must be moved to a separate VDC LAN, which also results in an adaptation of the IP configuration.<\/p>\n
![\"vCloud](\"https:\/\/serverbase.ch\/wp-content\/uploads\/2019\/02\/zugriff-mit-subnetzwechsel-1600x917.png\")
Moving the migrated VMs to a separate VDC LAN results in a change in IP configuration, while maintaining complete independence from the on-premise infrastructure. LAN1 and VDC LAN can be connected to an IPSec VPN.<\/p><\/div>\n
Access to on-premise systems continues to be via the on-premise Internet connection and access to the migrated VMs directly over the VDC Internet. If, for some reason, it is not possible to move the VMs to a separate VDC subnet, but still achieve independence, there is a workaround with a virtual firewall appliance between Extended LAN1 and VDC LAN.<\/p>\n
![\"vCloud](\"https:\/\/serverbase.ch\/wp-content\/uploads\/2019\/02\/zugriff-ohne-subnetzwechsel-mit-firewall-1600x910.png\")
The Extended LAN1 can not connect to the Layer 2 VPN and the VDC Edge Gateway at the same time. However, using any virtual firewall appliance, it is still possible to realize the concept of a second gateway in the Extended LAN1. The default gateways of the VMs must point to the virtual firewall, thus achieving the independence of the on-premises infrastructure.<\/p><\/div>\n
With the virtual firewall as the second gateway in the Extended LAN1 and the adaptation of the default gateway of the migrated VMs, the decoupling of the on-premises infrastructure succeeds. From now on, access to the Internet on VDC systems will be via the VDC’s Internet connection.<\/p>\n
Conclusion<\/h2>\n
The vCloud Extender is a much-anticipated tool for migrating on-premise workloads into Virtual Datacenter and for deploying hybrid architectures. The handling is simple, the migration process very slim and the downtime minimal. There’s nothing to stop you from migrating to the Virtual Datacenter.<\/p>\n","protected":false},"excerpt":{"rendered":"
