5 There is also typically a load-and-scale aspect to most of these services. You will need to properly size and architect how many connections each service can handle to determine the proper number of controller servers you need for, say, 5,000 connections with HA. You can then determine whether you're going to deploy all the controller servers for 5,000 connections up-front or add them as you scale your deployment. If you plan to scale past this number, you can use these details to continue to scale the different services and stay in compliance with best practices and supported maximums. The next consideration is operations, where it's necessary to understand how to patch and upgrade all the services in the deployed EUC broker. Beyond the services we've already discussed (typically contained in all server VMs deployed), there are also agents and clients you need to maintain. The agents are contained in the images used to deploy the pools of application servers and desktops users connect to. How you update the agents depends on how you provision these pools. The clients are located on the endpoints users use to connect to these services, which vary greatly depending on the style of endpoint. Despite the name, you can actually deploy a traditional on-prem broker in a public cloud. It nearly always makes more sense to deploy it on-prem, hence the name. Cloud Broker Cloud brokers are offered as-a-service in the typical Software-as-a-Service (SaaS) model and are most commonly referred to as a Desktop-as-a-Service (DaaS) offering. Several vendors and products fall into this category. Public cloud providers have their offerings, however since Citrix is the clear leader in the EUC market, Citrix Virtual Apps and Desktops Service (CVADS) offering is a logical place to start evaluating the benefits of DaaS. Most of the offerings provide a set of features on par with those provided by their traditional on-prem counterparts, but that's not to say they don't have their own benefits and limitations. There are many different DaaS offerings available from software vendors, cloud providers, and service providers. They vary widely in what they offer when you look beyond the big features like VDI and application presentation, which is why it is important to understand your use cases and their requirements when making a decision.
