This may sound surprising, as cloud databases are growing in popularity. However, this growth is not as fast as might be expected. What might be behind the trend? Some suggest that fears of vendor lock-in could be to blame. Read on here for more details.
Matt Asay writes, “Cloud databases may be to blame for NoSQL’s stalled momentum in 2016, but they may be seeing their own growth level off a bit. Using DB-Engines’ database popularity rankings, which amalgamate a range of datasets including Stack Overflow mentions and job postings, it’s clear that cloud databases keep leaping toward the world’s top-25 most popular databases (Amazon’s DynamoDB has already made it). It’s also clear, however, that they’re no longer getting there quite as fast.
“This doesn’t suggest we’re anywhere near the apex of cloud database adoption, but rather that developers may not be ready to fully give their infrastructure and data to the cloud providers.
“Reading the DB-Engines tea leaves, it’s clear that cloud databases keep growing. How much? Try 10X over the last four years … That’s the good news.
“To get at the bad news, it’s helpful to review how DB-Engines compiles its data: ‘We calculate the popularity value of a system by standardizing and averaging of the individual parameters. These mathematical transformations are made in a way so that the distance of the individual systems is preserved. That means, when system A has twice as large a value in the DB-Engines Ranking as system B, then it is twice as popular when averaged over the individual evaluation criteria. In order to eliminate effects caused by changing quantities of the data sources themselves, the popularity score is always a relative value, which should be interpreted in comparison with other systems only.’
“With this ‘relative ranking’ in mind, it’s notable that cloud databases aren’t making as much headway against the established leaders as one might expect, given the popularity of AWS, Microsoft Azure, and Google Cloud.”
