Sure, Internet communications relies on both and you cannot swap one with another. This thread is about load balancing and both can be used for load balancing (Basically DNS resolving to Anycast IP vs DNS resolving to Unicast IPs).

What's the difference between an anycast IP and a unicast IP?

Answer: Nothing. They are just IPs.

Using a combination of Anycast and DNS is going to give the best control over steering http traffic. Particularly if you own a few prefixes and can do clever addressing tricks.
