Faster, More Stable Monitoring for Hybrid Environments
A new enhancement in the iCluster Web Console delivers quicker dashboards, greater stability, and seamless operation when your systems span on-premises and IBM Cloud.
Overview
Keeping a clear, real-time view of your data replication and system health is essential — especially when your environment stretches across multiple locations. This release introduces a significant enhancement to how the iCluster Web Console gathers and displays monitoring information: the **Decentralized API**.
The result is a monitoring experience that is noticeably faster, more stable under heavy use, and purpose-built for hybrid environments where some systems run on-premises and others run in IBM Cloud.
Background
What is the Decentralized API?
The iCluster Web Console relies on background services (APIs) to collect monitoring and replication-group information from each system in your cluster and present it in the dashboard. In the past, all of that information had to be gathered by a single system that acted as a central collection point — it reached out to every other system, waited for their responses, combined everything, and only then returned the results to the console.
The Decentralized API*changes that approach. Instead of routing everything through one system, the console now gathers information **directly from each system that owns the data** and brings it together for you. No single system carries the entire monitoring workload anymore.
Why do we need to decentralize it?
The old centralized approach worked well when all systems were close together, but it created real problems as environments grew and spread out:
- Delays added up. When the central system had to reach across long distances — for example, from an on-premises host to systems in IBM Cloud — the waiting time for each response accumulated, making dashboards slow.
- One system became a bottleneck. As more operators viewed dashboards and pages refreshed automatically, the central system became overloaded, which could slow down or interrupt monitoring for everyone.
- It was a single point of failure. If that one central system was busy or unavailable, the entire monitoring view could stall.
Decentralizing removes that bottleneck and single point of failure, which is why the change delivers such clear gains in speed, stability, and hybrid-environment support.
How do you use it?
The Decentralized API is a backend solution — the improvement happens automatically inside the iCluster Web Console. There is nothing new to learn and no interface to redesign. You continue to use the same monitoring dashboards you already know; they simply perform faster and more reliably. This enhancement is available in the iCluster 9.4.1 release.
Better Performance
- Faster dashboards. Monitoring pages load and refresh more quickly, so you spend less time waiting and more time acting on what you see.
- Consistent speed under load. Even when several operators are viewing dashboards at the same time, or pages are refreshing automatically every few seconds, response times stay fast and predictable.
- Efficient at scale. As you add more replication groups, journals, or sites, performance holds up. The monitoring experience grows smoothly with your environment instead of slowing down.
- Quicker decisions. Faster insight means your operations team can respond to emerging replication issues before they turn into incidents.
Greater Stability
- No single point of failure. Monitoring no longer depends on one system carrying the entire load. If one system is busy, slow, or temporarily unavailable, the rest of your view keeps working.
- Resilient during busy periods. Heavy dashboard usage and frequent automatic refreshes no longer overwhelm your environment, avoiding the slowdowns and interruptions that used to occur under pressure.
- Localized impact. If one system experiences a problem, the effect stays contained. You continue to see the information that is available, with enough context to act — instead of the whole interface stalling.
- Fewer disruptions. More stable monitoring means fewer unplanned interruptions and a lower day-to-day operational burden for your team.
Built for Hybrid Environments
Many customers now run replication across a mix of locations — for example, a primary system on-premises with backup or disaster-recovery systems in IBM Cloud. This enhancement was designed with exactly that reality in mind.
- Optimized for distance. When your systems are separated by geography — such as an on-premises host communicating with an IBM Cloud host — the enhancement minimizes the delays that naturally come with that distance.
- Reliable across regions. Monitoring stays responsive and dependable even when network conditions between your on-premises and cloud systems vary.
- Seamless on-premises and cloud operation. Whether your systems are local, in IBM Cloud, or a combination of both, you get a single, unified, up-to-date view of replication health.
- Confidence for hybrid and multi-cloud growth. The design embraces geographic distribution rather than working against it, so you can expand your footprint with confidence.
The Business Value
- Faster dashboards mean faster decisions — respond to replication issues before they become incidents.
- Fewer interruptions mean lower cost of ownership — less firefighting and fewer unplanned maintenance windows.
- Growth without re-architecture — add sites or increase workloads without redesigning how you monitor.
- Confidence in hybrid and multi-cloud — a design that assumes distributed systems and performs well across them.
What Success Looks Like
- Operators see consistently fast monitoring pages, even during the busiest periods.
- Issues are spotted sooner and with greater clarity, enabling proactive response.
- The system stays stable when many users are active or when a remote site experiences high network latency.
- Your team spends less time firefighting and more time improving service quality.
Proven Results: 9.4.0 vs. 9.4.1
Head-to-head benchmarking of the same workloads on the previous release (9.4.0) versus the new Decentralized API (9.4.1) shows dramatic, across-the-board improvements:
• Several times more throughput. The new release handled roughly three times as many monitoring requests in the same test, meaning your dashboards can serve far more activity without straining.
• Effectively zero errors. Where the previous release returned a meaningful share of failed requests, the new release completed the same tests with no errors at all — a clean, reliable result.
• Well over twice as fast. Typical response times dropped to roughly a third of what they were, so pages feel noticeably snappier. Under concurrent load — many users and auto-refreshes at once — the improvement was even greater.
• Worst-case delays nearly eliminated. The most extreme "slow moments" (the rare, painful stalls) were reduced by roughly twentyfold, so the experience stays smooth even in the worst cases rather than occasionally freezing.
• Stable over the long haul. In sustained "soak" testing, the previous release steadily degraded until a large portion of requests were failing. The new release stayed rock-steady with no errors from start to finish.
• Resilient under spikes. During sudden traffic bursts, the old release lost a share of requests, while the new release absorbed the spikes cleanly with none lost.
• Scales far higher under stress. The previous release began failing under even light concurrency; the new release kept running error-free at roughly ten times that concurrency level, showing far greater headroom for growth.

The Decentralized API is a backend enhancement available in the iCluster 9.4.1 release. If you run iCluster across on-premises and IBM Cloud locations, it is one of the most impactful performance and stability improvements to adopt — with no changes required on your side.
