Enterprise Agreement (EA) You still buy Azure services directly from Microsoft, but it`s a design for a large organization that can make a commitment to consumption. The minimum requirement is 3 years during which you must raise in advance the amount of money you retain. Under the same agreement, you can combine the Azure service part and the license part, simplifying internal purchasing procedures. The customer can directly create a new Azure subscription. The most important advantage is the amount of discount you get – this is quite important. For this nice discount, you are addicted for at least 3 years, and you can not reduce the consumption costs for this period. You can increase the engagement at any time, but you can`t reduce it, and the extras you need may not be associated with the expected discount.
