Learn English – the meaning of sentence “straight outta + city + state”

Ether, or æther, was the mysterious substance once thought to suffuse the universe and be the medium that propagated light (and radio waves once they were discovered). Before that, it was the material that suffused the realm of the Gods. So, to say that something is in the ether means that it is something being communicated from place to place; it has no precise location, just as a radio broadcast can be heard from many different places.

The idea of ether as the medium for light and radio died out after the Michelson-Morley experiment's null result.

The short answer is that this is marketing gobbledygook, and doesn't really say anything useful at all. State of the art is a well-known idiom, but state of the practice (which basically means "what the business or field is currently doing") is less well known and very jargon-ish, and I would guess that the writer was simply trying for a catchy way to end the sentence.

To venture an interpretation, I would suppose that the writer is saying that this company can take the latest concepts and advances (the state of the art) and help its clients put them into practice (e.g., implement them in the clients' own businesses in a practical and useful manner).
