Jelastic Cluster uses Google Cloud Platform APIs to allocate private networks and map subnets to virtual machines. A VPN allows access to any private network on any VM and end user containers use internal IP addresses from mapped VPNs to access the internet. Live migration of containers between VMs is possible through VPN, but routing all traffic through the VPN causes network overhead with high traffic or large numbers of VMs.

2. Jelastic Cluster uses Google Cloud API allocating
private networks and mapping the subnets toVMs.

3. VPN (PPTP) allows to get access to any private network
on anyVM

4. End users Containers use internal IP addresses from
mappedVPN to get access to Internet.

5. Live Migration of Containers is the key feature.
VPN allows Jelastic Cluster to migrate Containers betweenVMs.

6. However, this workaround has one issue.
Traffic is routed viaVPN toVMs where IP networks were mapped.
It causes network overhead in case of high traffic and big number
of VMs in the cluster.
