Load Balancer

Introduction​

senhasegura has a self-made load-balancer to interface all senhasegura instances running into cluster schema. The senhasegura Load-balancer is a ready-to-deploy and also a ready-to-use solution, configured to give the best performance over senhasegura functionalities.

Installation and usage​

Technical informations​

The senhasegura Load-balancer minimum requirements are:

  • 4GB RAM;

  • 2 vCPUs (4 vCPUs recommended);

  • 40GB vHD;

It will use the same SSL certificate installed into senhasegura instances. There is no need to install a particular SSL certificate for the load-balancer.

As it is a tailor-made product for balancing the senhasegura , the senhasegura Load-balancer has a very specific optimization, and should not be used to balance other applications. Therefore, we do not offer the option of changing the balancing method and/or monitoring methods to the customer. Its use the least connection algorithm for balancing mode.

info

senhasegura , using the active-active redundancy, can be integrated with lots of load balancer vendors, such as F5 Big IP, Citrix, IBM etc.

An example of senhasegura Load-balancer architecture

Using senhasegura Load-balancer you can also decide which service should be balanced. A company which uses SSH connections more than the others proxies, can isolate dedicate instances for a better performance.

OVA installation​
