Average 5.00 ratingApache Cassandra Consulting Services in Australia
CDU delivers full-lifecycle Cassandra consulting - from the first architecture decision to years of production operations. Every service below stands alone or plugs into a larger data platform engagement.
Apache Cassandra Consulting
A structured engagement that reviews your data model, cluster topology and operational gaps, then prioritises fixes against your timeline and budget.
Multi-Datacentre Replication Setup
Active-active replication across regions or cloud providers, built so a datacentre outage never becomes a customer-facing incident.
Cassandra Cluster Architecture & Design
We design ring topology, replication strategy and node sizing around your actual read/write patterns not a generic template.
DataStax Enterprise to Apache Cassandra Migration
Cut licensing costs by moving from DSE to open-source Cassandra without losing the enterprise features your team relies on.
Cassandra Data Migration Services
Move off Oracle, PostgreSQL, MongoDB or DataStax Enterprise with a zero-downtime cutover plan and dual-write validation.
Cassandra Security & Compliance Hardening
Encryption at rest and in transit, role-based access control and audit logging, mapped against APRA, ISO 27001 or your internal policy.
Cassandra Performance Tuning
We resolve compaction bottlenecks, hot partitions, tombstone build-up and GC pauses that are quietly slowing your cluster down.
Cassandra Version Upgrades
Rolling upgrades to Cassandra 4.x or 5.0 with a tested rollback plan, so you get the latest performance and storage engine improvements without the risk.
Cassandra Managed Services (DBA-as-a-Service)
Ongoing cluster operations, patching, repairs and on-call incident response during Australian business hours without hiring a full-time DBA.
Cassandra Monitoring & Observability
Dashboards and alerting across latency, compaction, repair status and node health, built in Grafana, Datadog or your existing stack.
Cassandra Health Check & Audit
An independent review of your schema, consistency levels, repair schedule and configuration, benchmarked against Cassandra best practice.
Cassandra Training & Team Enablement
Hands-on workshops that get your engineers confident with data modelling, CQL and day-to-day cluster operations.

Apache Cassandra consulting covers cluster architecture and data modelling, migrations from other databases or DataStax Enterprise, performance tuning, multi-datacentre replication, and ongoing managed operations. Most Australian businesses start with a health check or maturity assessment before scoping a larger project.
Cost depends on cluster size and scope. A fixed-price Cassandra health check is the usual starting point, followed by a scoped migration or tuning project, or an ongoing managed services retainer. We quote after a short discovery call once we understand your current setup.
A single-cluster migration typically takes two to six weeks, depending on data volume, downtime tolerance and how many applications read from the database. Multi-datacentre or multi-application migrations are usually rolled out in phases to reduce risk.
Apache Cassandra is the open-source database at the core of both. DataStax Enterprise adds commercial features such as advanced security, search and analytics on top, along with licensing costs. Many businesses migrate from DSE to open-source Cassandra to cut licensing spend once they no longer need those extra features.
Cassandra suits workloads with heavy write volume, time-series or event data, and a need for linear scalability across multiple regions without a single point of failure — think IoT telemetry, messaging, product catalogues or user activity feeds. If your data is highly relational with complex joins and lower write volume, a relational database is usually still the better fit.
Both. We run consulting engagements for architecture, migration and tuning work, and we offer ongoing Cassandra managed services — monitoring, patching, repairs and incident response — for teams that want day-to-day operations handled without hiring a dedicated DBA.
Yes. We design and implement active-active and active-passive replication across regions and cloud providers, including AWS, Azure and Google Cloud, so a single datacentre or region outage doesn't take your application offline.
Yes, including K8ssandra-based deployments. We handle cluster design, storage configuration, scaling and operational tuning for Cassandra running on Kubernetes, alongside traditional VM or bare-metal deployments.
The most common causes are a data model that doesn't match query patterns, compaction strategy mismatched to the workload, tombstone build-up, hot partitions and undersized JVM heap settings. Our performance tuning engagements start by diagnosing which of these is actually driving the slowdown, rather than assuming you need more hardware.
Yes. We work with businesses across Australia — Sydney, Melbourne, Brisbane, Perth and remote teams — with delivery and support scheduled to Australian business hours regardless of location.
