I've checked out the market and I think Big-IP/Viprion is the best ADC your money can buy at the moment. It has the features and innovations that demanding organizations like us desire in an ADC especially for diverse and complex application environments. F5 has a solid offering with its iRules, iControl and iApps and we use its DevCentral portal. We take advantage of the integration with both Eclipse and .NET/Visual Basic which is a nice plus.
Room for Improvement:
It’s quite expensive compared to the other vendors. F5 lacks a pay-as-you-grow licensing scheme as offered by other companies, which makes acquiring their products more expensive at the outset.F5’s support for low-end platforms is also dismal, with continued restrictions imposed on such systems making it difficult for them to cater to small to medium-sized business. You might be forced to buy more expensive systems just to get the features you want and not the performance benefits of the more expensive system.I'm also concerned about F5’s continued push on new hardware platforms to generate sales.Finally, one must be able to handle the complexity and knowledge required for deploying F5’s ADC products. Selecting a reliable and experienced partner is crucial to get the right configuration for your needs and for you to be able to maximize your ADC investment.
Top of the line ADC with great features. Just make sure you have the right partner in implementing your solution so as the business value of such an expensive product is maximized.
