Can we know more about these reasons?
Amongst others, Amazon
- is less user friendly, in comparison to Azure: this makes Amazon a little bit more error-prone,
- is less advanced when it comes to integration and/or compatibility with common software and/or software used by an average user on their PC,
- is a little bit slow in development of the cloud platform itself (note: I have to admit that Amazon often comes with some specific new cloud function or cloud service, but these types of re-invention of the cloud often are associated with other cloud providers offering the same, with Azure often offering an identical but improved functionality)
and one point of concern is the cost of Amazon: even though the prices are very similar of even identical amongst cloud providers, Microsoft has the strategy of offering a "big bang for the buck" and this often means a competitive edge in service AND price (that is, at least during a specific period of time, after which the whole cycle repeats).
In my humble opinion, the biggest problem with Amazon is that one does not really know what one gets.
And that is a huge problem, in the sense that one cannot afford to be a hosting provider choosing for Amazon and a specific type and size of cloud service, whilst having to conclude after some time that the type and size does not suffice for the original objectives, hence making it (one the one hand) rather troublesome to migrate to another cloud provider and (on the other hand) very costly, when being forced to stay at Amazon with increased sizes of the cloud services originally chosen.
This is a reality: there is a (relatively) huge migration from Amazon to Azure nowadays and most of those migrations are motivated by the argument "we started small and the costs have risen to several thousands per month".
Sure, I have to be honest and say that every company (one the hand) has a personal bias and preference when choosing a cloud provider and (on the other hand) will end up with the subjective perceptive that cloud based services are more expensive than expected.
But in general, the numbers are crystal clear: Azure's market share is going through the roof, at the cost of Amazon's market share........not without reason.
