Building Endurance: A load balancer with a clear purpose

IT infrastructure doesn't stand still. While you're managing today's applications and services, tomorrow's challenges are already taking shape—think hybrid clouds, containerized workloads, DevOps automation, and the relentless demand for both reliability and agility.

We've watched this evolution closely, and we realized something important: the next generation of infrastructure management couldn't be built on yesterday's foundations. It needed to be architected from the ground up for the world that's emerging.

That's why we built Endurance.

After years of listening to customer feedback and watching the infrastructure landscape evolve, we made a decision that, honestly, kept us up at night: we started from scratch. Not because our existing solutions weren't working—our Enterprise product will continue to serve customers both now and for years to come—but because we saw an opportunity to reimagine what was possible.

Understanding the modern infrastructure challenge

The infrastructure world has fundamentally changed around all traditional platforms. What worked perfectly in 2015 faces new challenges in 2025, and we could see where the industry was heading.

The signs were everywhere:

• Monolithic architecture that made updates risky and time-intensive. Every change required extensive testing cycles and careful deployment windows. Teams were spending more time managing the platform than leveraging it.
• Limited API capabilities that hindered automation and DevOps integration. In a world where everything else speaks REST APIs and integrates seamlessly with CI/CD pipelines, manual configuration files felt increasingly outdated.
• Manual configuration requirements that increased operational overhead. Network teams became bottlenecks as application engineers waited for load balancer changes. The division of responsibilities that once made sense now slowed everyone down.
• Lack of real-time feedback and visibility into system changes. Engineers deployed changes and hoped for the best, with limited insight into performance impacts until problems arose.

It was painful to admit, but we knew we had to do better.

What modern Engineers actually deserve

Today's engineers operate in containerized environments, hybrid clouds, and distributed architectures. They deploy multiple times per day, not multiple times per quarter. They expect their tools to integrate seamlessly with existing toolchains and provide immediate feedback on changes.

Most importantly, they refuse to trade reliability for agility—and they shouldn't have to.

The engineers we work with every day need:

• Zero-downtime operations with instant rollback capabilities when changes go wrong. No more hoping deployments work; if they don't, teams can instantly revert to the previous working state.
• API-first design that enables full automation and seamless integration with existing toolchains. Every function accessible through a modern RESTful API, with real-time updates via WebSocket connections.
• Real-time visibility into system status, changes, and performance metrics. Teams need immediate feedback on the impact of their changes, not delayed reports or manual checks.
• Platform-agnostic flexibility that works across virtual, containerized, and hybrid environments. One platform that adapts to your infrastructure, not the other way around.

What Endurance delivers

Endurance represents our complete reimagining of what an application delivery platform should be in 2025 and beyond. Built from the ground up with modern technologies and architectural principles, it eliminates the fundamental tensions that plague legacy platforms.

Benefits for Development teams

• Modern Angular frontend with WebSocket-driven real-time updates provides immediate visibility into system changes and performance metrics. No more refreshing dashboards or waiting for status updates.
• Fully RESTful API backend enabling headless operations and custom integrations. Every function is API-accessible, making automation straightforward and comprehensive.
• Transactional change system with commit/rollback capabilities for safer deployments. Changes are atomic—they either succeed completely or roll back instantly.
• Built-in automation hooks for CI/CD pipeline integration. Endurance speaks the same language as your existing development tools.
• Snapshot-based rollbacks that instantly revert to previous working states. No more troubleshooting failed deployments under pressure.

Benefits for Operations teams

• Enhanced HA with N+ passive appliance support and zero configuration drift ensures true enterprise-grade reliability.
• Comprehensive alerting and monitoring with service-level log filtering shows you exactly what you need, when you need it.
• Step-by-step wizards that eliminate manual configuration file editing and reduce operational overhead.
• Automatic configuration backups for audit trails and recovery provide complete visibility into what changed, when, and by whom.

Benefits for Security and Compliance

• Role-based access control (RBAC) with granular permissions supports distributed teams and third-party integrations while maintaining security boundaries.
• ACL wizard for simplified policy creation and management makes complex security configurations accessible to operations teams.
• Secure, modern operating system foundation eliminates legacy security concerns while providing enterprise-grade protection.

Seamless integration with the ADC Portal

Endurance integrates seamlessly with our ADC Portal, providing unified management across your entire infrastructure. The Portal gives you a single consolidated view of all your load balancers, enhanced visibility and automation capabilities, improved security management, and the ability to organize and scale effortlessly using custom Namespaces, Labels and Tags.

This integration means engineers can migrate to Endurance gradually, managing both old and new infrastructure through a single platform—making infrastructure evolution possible, not painful.

Built for the future

Endurance isn't just a product upgrade—it's our platform for the next decade of growth. By building on modern technologies and architectural principles, we've created a foundation that:

• Accelerates feature development through modular, maintainable code
• Enables new market opportunities in DevOps-driven and containerized environments
• Reduces customer total cost of ownership through improved automation and reliability
• Future-proofs technology stack for emerging infrastructure patterns

Making the migration simple

We understand that platform migrations can be disruptive. That's why Endurance includes comprehensive migration tools, and our 5-star support team can guide you through every step of the transition process.

• Pooled licensing model maximizes deployment flexibility while providing cost predictability.
• Reduced operational overhead through improved automation and visibility means engineers spend less time managing the platform and more time delivering value.
• Platform compatibility ensures Endurance works with your existing infrastructure investments, whether virtual, containerized, or hybrid.

The truth about why we built this

I'll be honest with you: building Endurance was scary. Scrapping years of development and focusing 90% of our developers on starting afresh meant admitting that our previous approach had limitations. It means telling teams who relied on our Enterprise platform for Zero downtime that we were betting everything on something completely new. But we kept coming back to one simple belief:

Engineers deserve tools that amplify their capabilities, not constrain them. Ensuring that their clients’ businesses are never interrupted.

Endurance solves the fundamental tension between reliability and agility that engineers face every day. It delivers enterprise-grade stability with hybrid flexibility, ensuring that engineers never have to choose between uptime and innovation.

This is more than a load balancer—it's a modern, resilient control layer that transforms how engineers manage traffic, automation, and uptime-critical services across any environment. Combined with the ADC Portal's comprehensive management capabilities, it represents the future of application delivery.

We might be wrong about some of the details. We might need to adjust, iterate, and improve. But we're confident about this: the future belongs to platforms that refuse to make engineers choose between stability and agility.
