Some load balancers can also offload the encryption process. Authentication Profiles: - Authentication profiles allow BIG-IP to authenticate clients with the assistance of authentication servers prior to load balancing traffic to Pool Member. One caveat is that Hue’s underlying Thrift libraries reuse TCP connections in a pool, a single user session may not have the same Impala or Hive TCP connection. In addition, there are two other types of load balancing for advanced use cases; an internal load balancer for internal TCP/UDP-based traffic and a network load balancer for all other TCP/UDP and SSL traffic on ports that are not supported by the standard HTTP/HTTPS, SSL proxy, and TCP proxy load balancers. AWS Documentation » Elastic Load Balancing » Classic Load Balancers » Listeners for Your Classic Load Balancer » Listener Configurations for Classic Load Balancers The AWS Documentation website is getting a new look!. Components Configured in this section. Third-party modules can add support for additional protocols and load balancing algorithms. When Avi Networks sought to create a new L4 - L7 application services fabric, we fundamentally rethought the role of the load balancer. com offers free software downloads for Windows, Mac, iOS and Android computers and mobile devices. If you TCP load balance you should be able to do SSL offloading just like with PgPool or PgBouncer, at least with a smart enough load balancer. Network Load Balancing can be used to scale applications that manage session state spanning multiple connections.
