With open source filling mission-critical niches everywhere, we look at the drivers
Many projects revolve around small utilities, component parts rather than enterprise suites, but the latter exist too and may be downloaded from GitHub or subscribed to on AWS, Azure, Alibaba and other cloud service providers (CSPs).
And there are specialist CSPs that host only open source projects for a specific set of use cases. One such is Aiven, which provides managed services around a stack of open source databases, streaming and monitoring tools to customers including the UK Government and Toyota. Supported projects include Postgres, Cassandra, Elasticsearch and Kafka. CEO Oskari Saarenmaa said demand is being driven by the exponentially rising number of connected devices and the need to manage "the firehose of data" they produce. Frequently, open source solutions can be found where no others exist, he said, but many lack polish and are hard to use.
"We wanted to build a platform that brings the best of these technologies in front of people who are building something new and don't want to take ownership of all the systems and have to learn all the quirks and gotchas," said Saarenmaa.
Most open source projects fall into one of two camps, according to Saarenmaa. There are the collaborations between vendors, customers and academia to create software to "solve big problems for big companies". These may make money for a couple of the vendors involved but even those firms don't own the project or have a controlling stake in its overall development. In the database world, Postgres would fall into this category.
In the other camp are projects that are largely controlled by one company which may own the core IP, an example being MongoDB.
Somewhere between these two sit companies that are built on projects that are maintained by a foundation. Confluent was set up by some of the original creators of Kafka, but Kafka is an Apache Software Foundation project. Databricks is similarly placed with Apache Spark.
Saarenmaa believes that ultimately it's the collaborative efforts that will survive and thrive. Noting that MongoDB, Redis Labs and Confluent recently licensed some non-core modules under a restrictive non-open source license to prevent what they see as predatory actions by the big cloud companies, he said this move, while completely understandable, may backfire in the long term.
"We believe that the best thing is to stay open and to be backed by many contributors. There may be something behind the claim but the truly successful projects that will be around for a long time will not be controlled by a single company."
The accusation that Amazon in particular has taken a lot without giving much back is fair, he said, but open source projects have gained by the network effect of being hosted on AWS. "[It is] giving an opportunity for people to work with different kind of companies and users of open source software that they probably would not have bumped into otherwise," said Saarenmaa.
In a recent piece for Computing, EnterpriseDB senior sales engineer Jan Karremans said that open source projects should link together in a more customer-focused way than they have in the past. "A more pragmatic response would be to acknowledge it is a trend and discuss what it means for open source models moving forward without portraying it as a scene from Game of Thrones where good battles evil," he said.
However, for Confluent, VP product marketing Gaetan Castelein described the application of more restrictive terms to some of its modules and connectors as ‘uneventful'. Relations with Apache and the Kafka developer community have not changed, he said, nor have relations with CSPs soured, and for end-users things look the same.
"You can still have access to open source, you can still modify the code, so it looks and feels as if it was open source, the only change is if you're a cloud service provider. You cannot use these products to compete directly against Confluent."
So far this had not occurred, Castelein said, and the Confluent Community Licence was really a precautionary measure.
The past few years has seen a trend for more permissive licensing, with Apache 2 and MIT winning out over the older GPL models, mostly for reasons of reduced complexity: customers want to avoid the legal wrangles that can occur by mixing differently licensed software, and this filters down to developers. This is unlikely to change and so it could be that MongoDB, Redis Labs, Confluent and others find themselves on the wrong side of the fence - even if their changes are aimed at protection from CSPs. Only lawyers like complexity, after all.
