Are load balancing and QoS important when networking across clouds?
Quality of Service (QoS) is going to be tough because you don't own your own network. I think the core connection between your on-premises infrastructure and your public cloud infrastructure is critical in determining QoS. To that end, you will see more organizations implement point-to-point telecommunications products to ensure there is a great connection between those two environments.
This process is really no different than extending your data center from one location to another. Let's say you brought a physical data center online. You certainly would want to make sure you had QoS, uptime, availability and performance on that link. To that extent, I don't think those business requirements are any different, whether you're in the public cloud infrastructure or not. The tools and technologies you can put at both endpoints will be different, however. While you obviously can control your own physical endpoint, public infrastructure cloud providers can't necessarily install equipment or software to control the other endpoint. You're sort of at the mercy of some of the other cloud providers to say, "Okay, what can I do? What can I put at that endpoint to do monitoring or service monitoring?"
