挑战
Capgemini had built out a multi-tenant data center to serve its customers. Using VLANs, Virtual Routing and Forwarding (VRF), firewall rules and application delivery controller (ADC) partitions, Capgemini ensures that each customer’s environment is secure and isolated. Capgemini had deployed Cisco ACE load balancers to load balance web, mail and other applications in the multi-tenant data center. However, the existing Cisco ACE load balancer hardware was running out of available virtual context, couldn’t be upgraded and was having issues – so another solution was needed fast.
解决方案
Verbeek considered several vendors before choosing A10 Thunder™ Series. He went with A10 because the large number of configurable Layer 3 Virtualization (L3V) partitions makes it very suitable for multi-tenancy, A10 has a positive reputation with virtual applications and he liked the price/performance. The A10 Thunder solution was deployed in two distinct topologies on Capgemini’s network. One is where a partition of the A10 Thunder solution is part of the DMZ; in the other, it is placed in the same VLAN as where the real servers are located. When it’s placed in the same VLAN as the real servers, it is only used to load balance traffic that is destined for these real servers. Connectivity to other VLANs from a real server VLAN is not allowed. Since it provides the most flexibility, deploying the A10 Thunder solution in the DMZ is the default deployment. In this scenario, a single partition is allowed to reach multiple real server VLANs. When the A10 Thunder solution is deployed in front of a web-based application, source NAT and client IP header insertion are used to transport the traffic to the real servers. This is to make sure that the return traffic passes back to the A10 Thunder solution, since the default gateway usually points to the firewall.
