Developer Certifications

Why should you become a DataStax Certified professional?

The demand for Apache Cassandra® and NoSQL skills is skyrocketing, with Cassandra developers commanding 31% higher salaries, the highest of any database technology.

An Apache Cassandra® Administrator Associate Certification, Apache Cassandra® Developer Associate Certification, or Apache Cassandra® K8ssandra Associate Certification is the best way to get started learning and mastering the popular NoSQL database used by teams at Apple, Netflix, Sony, Uber, and thousands more.

An official certification helps you gain confidence in your knowledge of Apache Cassandra® and increases opportunities for career advancement.

Which certification should I pursue?

The Developer Certification is designed for professionals that use Apache Cassandra clusters to manage data. This includes roles such as application developers, data architects, database designers, and database administrators.

The Administrator Certification is designed for professionals who install, configure, manage and tune the performance of Apache Cassandra clusters, such as database administrators, DevOps engineers and Site Reliability Engineers (SREs).

The K8ssandra Certification is designed to up-level your DBA know-how to SRE skills. The topics covered in this exam include Docker, basic Kubernetes constructs, Sidecar, secrets, port-forwarding, helm, ingress, storage, Reaper repair, Medusa backup, K8ssandra, the cass-operator, Prometheus metrics collection, and Grafana metrics display.
