In this chapter, you gained a solid understanding of what load balancing is and why we need it for our XenApp implementation. In the field, I often work with customers who upon seeing NetScaler in action immediately find many other use cases for it in their existing infrastructures just because it's so versatile and feature-rich. In this particular scenario, you learned how to configure load balancing services in Citrix NetScaler to enhance performance and avoid single points of failure in the StoreFront environment. With this setup in place, we have completed the access layer. In the next chapter, we will go back to our Delivery Controller to start building XenApp workloads for application and desktop delivery. Stay tuned!
