Migration execution. Performance optimization. Training and certification. Delivered by the engineers who built Apache Flink. ## Who offers Apache Flink consulting and professional services? Ververica Professional Services provides Apache Flink consulting for teams running Flink and the Ververica platform. It covers architecture design, migration from open-source Flink, Spark Streaming or Kafka Streams, performance tuning, Flink job code reviews, upgrades and training, and a resident engineer can join your team for longer projects. ## Jump-Start and Boost Services - Launch New Use Cases - Flink Job Code Review - Platform Installation - Healthcheck - Platform & Flink Training - Flink Version Upgrades ## Adoption and Expansion Services - Resident Engineer - Platform & Flink Training - Launch New Use Cases - Custom Connectors - CI/CD Integration - Observability Integration - Platform Upgrades - Healthcheck ## Scale and Optimize Services - Performance Tuning - Platform & Flink Training - Flink Job Code Review - Architecture Design Review ## Professional Services From the original creators of Apache Flink®. ### Architecture Consulting Stream processing architecture decisions are expensive to reverse. Topology, state management, partitioning, and connector selection determine performance, cost, and operational complexity for years. - Stream processing architecture design aligned to your workloads and SLAs - Technology selection and integration patterns - Capacity planning and resource sizing - High availability and disaster recovery design - Data governance and compliance architecture - Reference architectures and implementation roadmaps Our architects have designed stream processing systems at the largest banks, retailers, and technology companies in the world. They wrote the code that became Apache Flink. ### Migration Services Migrating to stream processing, or migrating between platforms, carries risk. Data continuity, application compatibility, and operational readiness all require planning and execution discipline. **Migration Paths We Execute:** - Batch-to-streaming migration for real-time analytics and operations - Open-source Flink to Ververica Platform for enterprise governance and VERA performance - Spark Streaming to Ververica for lower latency and true stream processing - Kafka Streams to Ververica for complex event processing and multi-source joins - Cloud-to-cloud migration for infrastructure consolidation - On-premises to BYOC for operational efficiency **Migration Process** 1. Assessment of current workloads, dependencies, and SLAs 1. Migration plan with risk analysis and rollback procedures 1. Application porting and testing in parallel environment 1. Cutover execution with zero-downtime procedures 1. Post-migration validation and performance benchmarking ### Performance Optimization Running stream processing and running it well are different problems. Throughput bottlenecks, state management overhead, garbage collection pauses, and serialization costs accumulate. Small inefficiencies compound at scale. What We Optimize - Throughput: Identify and eliminate processing bottlenecks - Latency: Reduce end-to-end latency from source to sink - Resource utilization: Lower CPU, memory, and storage consumption by up to 52% with VERA engine tuning - State management: Optimize checkpoint intervals, state backends, and compaction - Serialization: Reduce serialization overhead for high-volume workloads - Scaling: Configure auto-scaling policies for variable load patterns Optimization engagements typically deliver 30-50% resource reduction on existing workloads. Measured before and after. Not estimated. ## Engagement Models Ongoing access to Ververica architects and engineers. Architecture reviews, design guidance, and technical advisory on demand. Quarterly business reviews. Named contacts. Fixed-scope engagements for migrations, architecture design, or optimization projects. Defined deliverables, timelines, and success criteria. A Ververica engineer embedded in your team. Full-time or part-time. Hands-on development, operations, and knowledge transfer. Duration matched to your project timeline. ## Frequently Asked Questions ### Do I need professional services to deploy Ververica? No. BYOC and Self-Managed include documentation and support for self-service deployment. Professional services accelerate complex deployments, migrations, and architecture decisions. ### Can professional services work with my existing technology stack? Yes. Our team integrates with your existing infrastructure, monitoring, identity, and CI/CD systems. We do not require you to replace working components. Engagements focus on stream processing, not rearchitecting your entire stack. ### What is the typical engagement duration? Architecture consulting runs 2-4 weeks. Migrations range from 4-16 weeks depending on complexity. Optimization engagements typically complete in 1-2 weeks. Resident engineer placements run 3-12 months. ### Do you offer remote services? Yes. All service categories are available remote. On-site delivery is available for organizations that require in-person engagement. Most engagements use a hybrid model with on-site kickoff and remote execution.
