Application Availability

Application Availability


Application high-availability requires that business-critical processes continue to run and users continue to experience uninterrupted access in the event of planned and unplanned circumstances. From server load balancing, link load balancing and global server load balancing, to WAN optimization for back-up and recovery, to remote access for business continuity, solutions for application availability play a critical role in guarding profitability and maintaining workforce productivity.



Challenge

Solution

Ensure an uninterrupted application experience in the event one or more servers become overloaded or unresponsive

Server load balancing with application and server health checks for maintaining session and transaction persistence

Maintain 24/7 connectivity between corporate networks and the Internet

ISP and link load balancing for redundant connectivity to the Internet

Route requests to redundant data centers in the event of local disruptions

Global server load balancing for seamless fail over of application traffic to alternate data centers in the event of geographic disruptions

Increase the frequency of backup and replication to better mirror data and enable more seamless failover to redundant datacenters

WAN optimization for accelerating data transmission across wide area networks and reducing the time necessary for backup and replication

Enable remote and mobile access to business applications from anywhere and any device to ensure business continuity in the event workers cannot get to their place of work

Scalable, secure remote access with burst licensing for cost-effectively supporting spike usage caused by business continuity events



Load Balancing, WAN Optimization and Remote Access for Application High-Availability


Array application availability solutions provide load balancing, backup and failover for servers, WAN links and data centers to ensure applications remain up and running in the event of disruptions large or small. To ensure workers can access applications, even if they cannot get to work, Array remote access solutions support connectivity from any device, anywhere and offer flexible licensing options that make preparing for surge usage both affordable and predictable.


Business disruptions can take many forms, from equipment failures and network outages, to minor events such as sick days, to major events such as extreme weather and natural disasters. Leveraging Array application high-availability solutions, businesses can ensure that core systems are always up and running and workers always have access to the applications and resources essential to accelerating business.





Server load balancing improves application availability by intelligently directing Layer 2-7 traffic based on a broad range of application metrics and health checks. In addition to distributing traffic loads and directing requests away from overloaded or unresponsive servers, Array load balancer solutions support Layer 4 connection persistence, Layer 7 application persistence and site-level persistence for ensuring the continuity of client sessions and online transactions.
