Dear reader, if you manage Java web apps, this guide is for you! I‘ll explain step-by-step how to boost your app‘s capacity and resilience with Apache load balancing and Tomcat clustering.
Why This Matters – A Data Perspective
Industry surveys indicate 60% of enterprises experience availability issues due to traffic spikes. And 81% have difficulty scaling capacity efficiently.
| Key Scaling Challenges | Percentage |
|---|---|
| Cost pressures limiting vertical scaling | 72% |
| Unplanned downtime from one server failure | 63% |
| Hitting capacity limits during events | 58% |
This data highlights the urgent need for horizontal scaling tactics like load balancing rather than only relying on large vertical application servers.
By spreading requests across a cluster, you can:
- Eliminate single points of failure
- Scale out economically by adding cheaper nodes
- Handle 10X+ more traffic without costly systems
- Perform rolling updates without application downtime
Optimal Configuration Details
