Hybrid cloud performance depends on addressing these latency challenges. By combining monitoring, optimised configurations, and expert strategies, businesses can maintain fast, reliable operations.

5 Main Sources of Hybrid Cloud Latency

Physical Distance Between Data Centres

The sheer physical distance between data centres is a fundamental factor in hybrid cloud latency. Data can only move as fast as the speed of light, and the greater the distance, the longer it takes. Here's a breakdown of how distance impacts performance:

On top of this, system resource limitations can amplify latency issues.

System Overload and Resource Limits

While distance sets a baseline, system overload can push latency to unmanageable levels. When resources are stretched too thin, bottlenecks occur, leading to costly disruptions - estimated at £4,400 per minute during downtime. Common culprits include:

• Sudden traffic surges
• Inefficient database operations
• Memory leaks
• Poorly optimised caching mechanisms

Addressing these issues is crucial to maintaining consistent performance.

Network Setup Problems

Misconfigured or poorly designed networks are another major contributor to latency. These problems can grind data transfers to a halt. Some common network setup issues include:

• Limited LAN bandwidth
• Over-reliance on public internet connections
• Inconsistent security configurations
• Protocol mismatches

To meet high availability targets, such as 99.95% uptime (equivalent to around 22 minutes of downtime per month), organisations must carefully review and optimise their network architecture.

Multi-Cloud Connection Issues

Hybrid cloud environments often involve multiple cloud providers, and transferring data between them can introduce additional latency. For instance, the EllaLink subsea cable system has reduced transatlantic latency to as low as 60 ms, a 50% improvement in performance. Such advancements highlight the importance of optimising inter-cloud connections to minimise delays.

Blind Spots in Performance Tracking

A lack of effective monitoring can leave critical performance issues unnoticed, exacerbating latency. Here's how tracking specific metrics can help:

Proactive monitoring is essential, especially since as many as 90% of users may abandon a service after multiple poor experiences. Addressing these blind spots ensures a smoother, more reliable hybrid cloud experience.
