Two types of load balancing schemes can be used within the SoftLayer cloud:
- Local Load balancing. SoftLayer load balances traffic among two or more servers by using industry-standard techniques, such as round robin, lowest latency, and least connections. The embedded service is enabled and managed directly through the SoftLayer Control portal. The features of the local load balancer are relatively basic and simple; customers do have the option of using another vendor’s, such as NetScaler, load balancer.
- Citrix NetScaler VPX. NetScaler VPX load balances traffic between servers in SoftLayer data centers through Citrix’s cloud rendering engine. It is also possible to do a custom install using an infrastructure owned by the customer (i.e., virtual servers, bare metal servers). Click here to learn more about NetScaler VPX.
