VMware Tanzu GemFire Consulting, Licensing, & Support

1. 01

   The Broadcom renewal quote came back at a multiple of last year's and nobody can reconstruct the maths

2. 02

   Licensing moved to a per-core model and the existing cluster layout is now the most expensive shape it could be

3. 03

   Members drop out of the distributed system during GC pauses and the cluster spends the next hour rebalancing

4. 04

   A network partition left two halves of the cluster each believing it was authoritative

5. 05

   Region design puts partitioned and replicated data in the wrong places, so ordinary queries fan out across every member

6. 06

   Disk stores have grown past what oplog recovery can replay inside an acceptable startup window

7. 07

   WAN gateway senders queue during a link outage and never catch up once it clears

8. 08

   The engineers who designed the cache have left, and the remaining team will not touch region configuration

One heap ceiling, one read-only member

One service, one GemFire member, one database

Illustrative

Order service

Member heap

orders region

Database

1. 01Healthy

   The orders region sits in a partitioned region with a redundant copy. Heap stays well under the eviction threshold, and reads and updates are served from memory.

2. 02Heap past critical

   The region grew and a large OQL result added to the pressure. The member passes critical-heap-percentage and goes read-only, updates fail with LowMemoryException, and the service falls back to the database.

3. 03Fixed

   Heap and region sizing match the dataset, eviction overflows to disk instead of destroying entries, the thresholds sit below the GC danger zone, and updates succeed again. The database load drops. Is this happening on your GemFire? Get a quote

A GemFire member that runs out of heap rarely fails cleanly. The resource manager's eviction and critical thresholds are off by default, so teams meet the limit as a long GC pause, a member timing out of the cluster, or LowMemoryException. AceMQ checks eviction-heap-percentage, critical-heap-percentage, the eviction action on each region (local destroy drops entries, overflow to disk keeps them), off-heap sizing and the GC logs against member-timeout together, because heap and failure detection have to be tuned as one.

  GemFire Architecture & Cluster Deployment

  We design GemFire clusters from data model through production deployment — region type selection, WAN topology, JVM tuning, and security hardening. Every design decision is validated against your latency and throughput requirements before go-live.

  • Region design: partitioned vs. replicated selection, colocation strategy, and bucket count sizing
  • WAN Gateway configuration for active-active multi-site replication
  • JVM heap sizing and GC tuning (G1GC, ZGC) for sub-millisecond data grid operation
  • Security: TLS/SSL, authentication, authorization, and audit logging
• 02

  GemFire Spring Integration & Application Development

  We integrate GemFire into Spring Boot applications using Spring Data for Apache Geode — covering caching, session management, and repository patterns. PDX serialization enables polyglot client access across your stack.

  • Spring Data for Apache Geode / Spring Data GemFire configuration
  • Spring Session GemFire for distributed HTTP session management
  • PDX serialization for language-agnostic data access across clients
  • Spring Boot Auto-Configuration with GemFire client regions
• 03

  GemFire Performance Tuning & Capacity Planning

  Sub-millisecond latency requirements demand expert tuning. We profile GemFire clusters end-to-end and implement targeted optimizations that reduce P99 latency and prevent capacity bottlenecks.

  • Heap LRU eviction policy tuning and off-heap memory configuration
  • OQL query execution plan analysis and index design
  • Client connection pool sizing and server group load balancing
  • Capacity modeling: memory footprint per entry and growth projection
• 04

  GemFire Incident Response & 24/7 Support

  When your in-memory data grid fails under load, every millisecond matters. Our GemFire support team responds in 15 minutes and stays engaged until your cluster is stable and root-caused.

  • 15-minute emergency GemFire support response — senior engineers only
  • Cluster split-brain detection and recovery procedures
  • Out-of-memory and heap pressure incident response
  • Post-incident RCA with written findings and hardening recommendations

  GemFire Licensing & Subscription Management

  As a Broadcom Expert Advantage Partner, AceMQ procures and manages VMware Tanzu GemFire licensing from evaluation through renewal. We provide compliance audits and multi-year negotiation support with a 24-hour quote turnaround.

  • VMware Tanzu GemFire commercial licensing procurement and entitlement management
  • Broadcom licensing transition guidance post-VMware acquisition
  • License compliance audit: entitlement vs. deployed cluster node count
  • Multi-year contract negotiation and renewal optimization
• 15 MIN SLA

  24/7 GemFire Support

  Named senior engineers on your account — 15-minute emergency response, no ticket routing, no junior triage.

  • 15-minute emergency response SLA
  • Named engineer, zero cold-start
  • Proactive CVE & health monitoring
  • Quarterly deployment reviews

  Compare the four GemFire support stages

• Written findings before any change
• Changes made one member group at a time, so the cache stays up
• Your engineers in the room
• You keep the runbooks
• Ad hoc engagements or an annual partnership
