Your business depends on applications every day. But how you use those apps, and how you deliver them, is changing. That’s forcing you to re-evaluate your ADC strategy. How do you know which ADC investment will return the best value?
Application Delivery Controllers (ADCs) ensure consistent performance and availability of your applications. Like the apps they deliver, ADCs today are evolving and diversifying to meet the changing needs and expectations of the digital workplace. For instance, ADCs now come in hardware, virtual, and containerized form factors; they can be sized to meet your projected application usage; and they can be designed to integrate cloud-based apps with a centralized management solution. As you determine how to allot your ADC spend, you are making choices not only about your immediate costs, but about the future flexibility of your network, your ability to move work functions to the cloud, and the costs of refresh in years to come.
Citrix NetScaler is an industry-leading application delivery solution that secures and optimizes application delivery from a datacenter or from a cloud-based infrastructure. It ensures 100% application availability, enhances end-to-end application performance, secures applications by providing application layer attack protection, and improves application server efficiency—all in a single device, with unified, easy-to-define policies.
Three Possible Strategies for Your ADC Refresh Investment
1- Conventional Hardware
Most ADCs carry a fixed licensed capacity. Traditionally, when businesses needed to increase capacity, they either bought new appliances or upgraded the appliances they already owned. This buy-it-when-you-need it strategy makes short-term sense for companies that prefer to manage hardware on-premise and may not be ready to move to cloud. In the long run however, as business demands increase, recurring purchases can be expensive and disruptive, and can eventually lead to “appliance sprawl” which is costly to support.
2- Consolidation with Multi-tenancy
Many organizations are replacing multiple point solution appliances with a “scale in” approach. Rather than continue to buy more and more devices, they choose to go in the opposite direction, consolidating existing load balancers, VPNs and firewalls onto a multi-tenant platform—a single physical device that supports multiple tenants, and that over time, can scale up as needed, without the set-up and deployment requirements of complex upgrades.
3- Pooled Capacity Licensing
As applications transition to the cloud and the data center evolves towards a software defined model, the requirements for ADCs are rapidly evolving. A “software first” ADC decouples software from hardware, freeing you to allocate instance capacity flexibly across your network, in hardware or software either on-premise or in the cloud.
