The common configuration for high-availability infrastructure would include
load-balanced front-end Web servers, clustered application servers, a database cluster
with a separate standby replica, and mirrored onboard or external storage. Additionally,
at all layers of the stack, switches, routers, firewalls, and load-balancers are deployed
in pairs to eliminate any potential single points of failure. Finally, mirrored components
are split up among independent racks that reside on separate Power Distribution Units
(PDUs),which ensures that both fault domains remain completely discrete.
High-availability is an absolute requirement for today’s critical Internet applications. Logicworks offers high-availability solutions for every aspect of a client’s operating infrastructure: from the network core, to firewalls and load balancers, to databases and storage.
Logicworks engineering team has deep expertise and extensive hands-on experience in the critical and most challenging elements of high-availability implementations.
