Tyk supports native round-robin load-balancing in its proxy. This means that Tyk will rotate requests through a list of target hosts as requests come in. This can be very useful in microservice architectures where clusters of specialised services are launched for high availability.
Setting up load balancing is done on a per API basis, and is defined in the API Definition file/object:
proxy.enable_load_balancing: Set this value to
trueto have a Tyk node distribute traffic across a list of servers.
proxy.target_list: A list of upstream targets (can be one or many hosts):
"target_list": [ "http://10.0.0.1", "http://10.0.0.2", "http://10.0.0.3", "http://10.0.0.4" ]
Important: You must fill in the
See Service Discovery to see how you can integrate a service discovery system such as Consul or etcd with Tyk and enable dynamic load balancing support.
Configure load balancing via the Dashboard
To set up load balancing via the Dashboard, from the Core Settings tab in the API Designer select Enable round-robin load balancing from the API Settings options:
You can now add your Load Balancing Upstream targets.
