High Availability Architecture Patterns: Choosing the Right Approach
Key Takeaways
- Distributed Redis clusters across multiple regions ensure continued availability and resilience during regional outages or disasters, minimizing downtime for mission-critical RPA operations.
- Active-active clustering distributes workloads evenly and maintains availability during maintenance or unexpected failures, making it suitable for applications with dynamic and high-volume processing needs.
- Active-passive clustering prioritises continuity and reliability, offering a more straightforward setup ideal for steady workloads where consistent uptime is more critical than full resource usage.
- Database cluster setups like SQL Server ‘Always On’ improve fault tolerance by replicating primary databases, ensuring quick failover and data integrity during server outages.
- UiPath’s HAA Add-on with Redis ensures transaction consistency and automatic failover in clustered environments, strengthening the automation infrastructure’s high availability and reliability.
High availability is critical for organisations that rely on RPA to automate mission-critical business processes. Implementing high availability can be complex, and the specific architecture will depend on your organisation’s requirements and resources. UiPath provides documentation and support to help organizations design and implement high-availability solutions that fit their needs. Below are some key strategies to choose the right components for your organisation and achieve great results:
