Today’s ADCs are no longer just about load balancing. They are a mission critical component of delivering business applications for productivity, as well as customer-facing applications.
Here are just 5 essential ways they can help:
Security is one of the major concerns with any application exposed to the Internet. ADCs protect those applications with security features, like integrated web-application firewalls, DDoS protection, strong authentication, resource obfuscation, and content encryption. They are the front line, providing multiple layers of protection to external-facing applications.
- Availability and Reliability
Applications used for business processes or revenue generation simply can’t go down. An ADC provides reliability by ensuring that requests are sent only to available servers or redirecting requests when a server is down for maintenance. ADCs help provide Business Continuity and Disaster Recovery (DR) using global load balancing capabilities to seamlessly redirect requests from the primary data center to a secondary site or even a cloud DR presence, when needed.
Everybody wants better and faster performance! Dramatically improve your application performance using ADC features, like compression, caching, protocol optimization, connection management, and intelligent load balancing algorithms. Enhance mobile device performance and user experience by utilizing mobile-specific protocols like SPDY.
Easily scale up to meet demand without re-architecting your infrastructure or scheduling down-time. ADCs are an integral part of automation and orchestration for software-defined data centers. If an application is oversubscribed and performance decreases, a workflow can be automatically kicked off to spin up new web servers for burstable and dynamic application provisioning. Once the spike in utilization subsides, the extra servers can be automatically spun down for other users.
- Remote Access
An ADC can provide full-featured SSL VPN for granular remote access, whether it’s clientless VPN or a full client-server VPN tunnel. An ADC can proxy and optimize any Virtual Desktop Infrastructure (VDI) or Application Virtualization instance for a consolidated, secure, and flexible remote access solution. Policies can be assigned based on a number of parameters, including certificates, AD group membership, source-IP address, and more. The ADC will even do Single-Sign On, so end users have a simple, one-stop shop for all of their remote access needs.
