Show 47 – Load Balancers – Good Thing We Didn’t Step In It

Value market versus Enterprise Market

There is the load balancing market that most in networking are aware of, with vendors like Cisco and F5, and then there is the value market. Load balancers you can get for $2,500-$10,000 a piece (redundant coming in at around $5K to start, USD of course) that have many of the features of the big boys, but not necessarily the reputation. KEMP, Barracuda, just to name a few.

The double-edged sword of content manipulation (iRules, aFlex, etc.)

The benefit of iRules is that they can manipulate HTTP content and add application logic to the network layer. The drawback is that they can manipulate HTTP content and add application logic to the network layer.

It’s always the load balancer Load balancers get blamed disproportionately for issues. Although, sometimes it is the load balancer.

It’s 2011, why is DNS-based Global Server Load Balancing still my only option in most cases?

Will load balancers be the front line for the IPv6 conversion? IPv6 VIPs, IPv4 servers?

HTTP: The Undertaught Protocol

TCP One Connect / Session Termination – performance, security and design decoupling.


Load balancers versus Application Delivery Controllers (terminology and common parlance). It’s “Load Balancer” and never ADC. Vendors are pushing to call these devices Application Delivery Controllers, ADCs. I don’t think that name has stuck very well. Everyone I know calls them load balancers, and if I say ADC no one knows what I’m talking about. ADC is as meaningless as the word “cloud”
