Migrate Apache Kafka to Google Cloud Pub/Sub — Expert, Fixed-Scope Kafka
Yes, this migration is a well-understood project. We rewrite your consumer/producer logic from Kafka APIs to GCP Pub/Sub — safely, concurrently, with verification tools — while you keep vendor support.
The lowest-cost way off Apache Kafka: our migration tooling automates the repetitive work —you pay senior engineers for judgment, not keystrokes.
How we support Apache Kafka → Google Cloud Pub/Sub after migration
- ✓We rewrite Kafka API logic into Google Cloud Pub/Sub safely, line by line.
- ✓Both systems run concurrently — verify every message before cutover.
- ✓You shed partition management, replication policy, and cluster tuning.
- ✓Serverless Pub/Sub scales to global spike traffic automatically.
- ✓Senior engineers complete the project in 3–6 months, fixed scope.
- ✓Keep vendor support while you migrate; pay 40-70% less if you lapse.
Scaling Kafka for global traffic is expensive and slow
Your self-managed Kafka cluster can't handle global spike traffic. Every peak means scaling nodes, rebalancing partitions, and fighting replication lag.
Kafka drains dev resources you need for product features
You are shifting engineering workloads to GCP, but your messaging layer is still legacy Kafka. Developers must split attention between queue ops and product features.
Uncertainty about Pub/Sub's offset and partitioning model
You rely on offset rewind and custom partition keys — and you are not sure Google Cloud Pub/Sub can match those behaviors exactly.
Apache Kafka → Google Cloud Pub/Sub migration — your questions answered
What about offset rewind? Kafka offsets let you rewind. Does Pub/Sub do that?+
Yes. Pub/Sub uses seek() instead of offset rewind. We map your offset-based rewind patterns to Pub/Sub snapshot and seek logic so downstream consumers still reprocess messages as needed. It works differently but the result is the same: controlled replay.
We rely on custom partition keys to pin data to specific compute nodes. Can you handle that?+
Yes. We detect those partition key→compute affinities and redesign them as Pub/Sub ordering keys or topic-based routing. No loss of data locality.
What if our Kafka support contract expires before we finish migrating?+
Vendor support stays active as long as your renewal is in force. If the renewal lapses, our third-party support covers most operational issues on Kafka while you finish the move. It is not vendor support and does not include vendor patches — but it buys you time.
How much does a Kafka to Pub/Sub migration cost? How long does it take?+
Project budgets range from $60,000 to $250,000. Timeline is 3–6 months with 2–4 senior consultants. We bill fixed scope — no overruns.
Migrate Apache Kafka to GCP Pub/Sub with Confidence
Your move to Google Cloud Pub/Sub doesn't end at cutover. We help you set up cost tracking, real-time monitoring, and Dataflow stream processing so your new messaging layer runs cleanly from day one. Up to 40-70% savings on legacy platform support while you migrate.
