Business Continuity & High Availability

Ensure Always-On Operations with Zero-Downtime Infrastructure

Our Business Continuity & High Availability service eliminates single points of failure and ensures your critical systems remain operational 24/7/365. We design and implement redundant, fault-tolerant infrastructure with automated failover capabilities that keep your business running even during hardware failures, network outages, or planned maintenance. Using industry-leading clustering, load balancing, and failover technologies, we create resilient architectures that meet the most demanding uptime requirements. Our solutions include geo-redundant data centers, automated health monitoring, and instant failover mechanisms that activate within seconds of detecting a failure.

FAQs

What's the difference between high availability and disaster recovery?

High Availability (HA) prevents downtime from component failures using redundancy and automated failover. Disaster Recovery (DR) protects against catastrophic events that affect entire sites. Best practice is to implement both.

How long does failover take?

Failover times range from <1 second for active-active configurations to 1-15 minutes for active-passive, depending on architecture and technologies used.

Can we test failover without affecting production?

Yes! We design systems that allow transparent failover testing. Users won’t notice when we switch to backup systems during testing.

What's the difference between active-active and active-passive?

Active-active means both systems handle traffic simultaneously (load balanced). Active-passive means backup systems stay idle until primary fails. Active-active is more efficient but more complex.

Do we need separate physical locations for HA?

For true resilience against site failures (power, network, disasters), yes. However, local HA protecting against component failures can work in a single location.

What happens if both primary and backup fail?

We design N+1 redundancy with more than two nodes. We also integrate with disaster recovery solutions for catastrophic scenarios. The probability of multiple simultaneous failures is extremely low.

Can we implement HA for legacy applications?

Yes, though it may require creative solutions like clustering at the infrastructure level rather than application level. We’ve successfully implemented HA for many legacy systems.
