In this chapter, we saw that the varied load balancing solutions are available from proprietary vendors to open source solutions, and discussed the impact that microservices have had on load balancing, moving it from a centralized to distributed model to help serve east-west traffic.

We then looked at blue/green deployment models, the merits of immutable and static servers, and how software releases can be orchestrated using Ansible in either model. In the process, we illustrated how useful Ansible is at orchestrating load balancers by utilizing dynamic inventory, rolling updates, delegation, and jinja2 filters can all be used to help fulfill load balancing requirements.

The key takeaways from this chapter are that microservice applications have changed the way applications need to be load balanced, and distributed load balancing is better suited when deploying microservice applications, which have more east-west traffic patterns.

The reasons that immutable infrastructure is well-suited...
