Organizations turn to Microsoft because their product suite is able to check the boxes that IT staff, operational staff and procurement look for when making a purchase. Their server offerings, operating systems and applications make up the central core of many a business because they are known to be reliable, stable and capable for the task at hand.
Recently, Microsoft issued an end-of-life announcement that includes a number of products that a large percentage of organizations still rely on to handle day-to-day IT and end-user business functions. With a deadline of January 2020, this announcement has caught a number of organizations off guard or simply thrown businesses into a state of denial because they had not planned on upgrading or migrating away from any of the products mentioned in the announcement.
