Red Hat is clearly in the pole position. To its credit, it established itself as a noteworthy entity prior to others on this list. It was the first to go public, and it has not looked back. Even with traditional behemoths like IBM and HP breathing down its neck. Red Hat was smart to form partnerships with these larger entities, which helped catapult them to the number one position. The culmination of these strategic moves has resulted in a reading of between 800 and 900 over the course of the last six quarters. That is twice the results of the distribution in the number two slot.
