The days of having on-premise databases are behind us or are rapidly passing away. Cloud server hosting offered by Microsoft and Amazon makes up 75.5% of the market growth. If you have just started your business and looking to implement databases, you are less likely to get licensed software to install on the server in your office. You would instead look into AWS or Azure services, or maybe something else if you are a CRM platform system.
Companies like Cloudera and MapR went to cloud for their Hadoop implementations. So most of their big data is safely stored in the cloud server hosting.
But it isn’t limited to just startups anymore; medium-sized organizations are moving towards the cloud increasingly. On the other hand, it might take some time for large enterprises to move towards clouds based on the report by Gartner, The Future of the DBMS Market is Cloud.
