Move from proprietary licences to open-source Cassandra, Kafka and OpenSearch
Commercial distributions of Cassandra, Kafka and Elasticsearch can tie you to rising licence costs and one vendor's roadmap. Digitalis moves you to the open-source projects, Apache Cassandra, Apache Kafka and OpenSearch, with a planned migration and 24×7 support afterwards, so you keep expert cover without the licence.
It is time to review your licence when the bill grows faster than the platform
The renewal quote has jumped
The price has gone up without any new capability.
The licence terms have changed
New terms restrict how you can run, scale or offer the software.
Key features sit in a paid edition
You depend on functions that only exist in the proprietary version.
Your team still solves the hard problems
You pay for vendor support, yet your own engineers still do most of the troubleshooting.
You want to change cloud at the same time
The move off the licence can be combined with a move to new infrastructure.
Support has to continue after the switch
Critical platforms need expert cover on day one of the open-source version.
Four steps from licence to open source
Audit
We list the proprietary features you use and map each one to an open-source equivalent or an alternative approach.
Plan
Compatibility testing, a data migration approach, a rehearsed cutover and a rollback plan keep applications working.
Replace tooling
Monitoring, backup, security and management features are rebuilt on open-source tooling.
Support
Our 24×7 managed service covers the open-source platforms, so moving off the licence does not mean losing support.

Frequently asked questions
Are open-source Cassandra and Kafka ready for production?
Apache Cassandra and Apache Kafka are mature Apache Software Foundation projects run in production by large organisations. What a licence usually adds is support and tooling, which we provide.
Will we lose features?
It depends on what you use. Our audit lists every proprietary feature in use and whether it has an open-source equivalent, needs a different approach, or is not needed.
What is the difference between Elasticsearch and OpenSearch?
OpenSearch is an open-source fork of Elasticsearch, created in 2021 and licensed under Apache 2.0. We support both. See Elasticsearch services.
Do we have to change cloud provider?
The migration can stay on your current infrastructure. If you also want to move, we can combine the two. See migration and modernisation.
How long does a move take?
It depends on the size of the platform and the features in use. The audit gives you a plan and timeline before any work starts.
