Haas is a smart option for startup to mid-sized businesses that can't afford to have their own IT partner yet. Haas does not require big capital for small businesses to secure new IT equipment to run their operations. They get to upgrade the system as they grow without having to spend a lot.
However, Haas may not be very beneficial to large companies. This is especially true to companies that require huge hardware and servers. It is best that they have their own IT partner and in-house IT support to eliminate unnecessary services that they have to pay. Haas is no doubt a big help to smaller business that employ a few people, and those that are not yet ready to spend more for IT equipment and IT people.
