We haven’t expected much from our load balancers in the past. And why should we? Traditional load balancers had a relatively simple job (e.g. distribute traffic, SSL, some content switching), and functioned relatively well. End of story.
Last week, my colleague Chris wrote about his "buyer's remorse" (not!). If you are an F5 BIP-IP LTM (or a Citrix NetScaler SDX or MPX) customer, I would like to get you thinking about software load balancers.
I originally joined Avi Networks because I believed they had a robust, software-defined application delivery solution. It could do everything F5’s physical load balancers could do… or so I thought. After one week on the job, I’ve realized that Avi Networks only cuts costs by up to 70% only because you aren’t paying for hardware—hardware that can do a lot of things that Avi Networks just can’t do.
Unlike other countries, all U.S. citizens residing out of the country are required to pay their normal Federal taxes back to the “mother-ship.” This became painfully clear during my two tours of duty living in the United Kingdom. To make matters worse, the U.S. tax year has a different timing cycle than the U.K. tax year. Because of the offset tax years (and my domicile alternating twice between London and New York) I have spent the last six years filing taxes in both the United States and the United Kingdom. Not fun or easy to deal with.
Enterprises must undergo a digital transformation. It is not a matter of if, but when. And most IT organizations are choosing now as the time.
Load balancers became popular about two decades ago with the dawn of the Internet age. With the goals of optimizing the performance of newly created websites and ensuring that end users had a responsive experience when visiting a site, the load balancer was an essential front end to web servers and applications. The load balancer plays the traffic cop, using different algorithms to optimize the distribution of traffic to backend servers.

The way modern enterprises run their computing is changing at a rapid pace. With infrastructure choices and application architectures favoring flexibility above all else, legacy application delivery controllers (ADCs) are unable to keep up with the changing requirements.
When it comes to load balancers you have probably heard terms such as, "Software Defined Hardware" (yes, they actually said that!) or "Software First" from vendors like F5 Networks and Citrix NetScaler. What they are really telling you is that they understand the importance of software, but need to keep selling you hardware.
Cisco announced the end-of-support of their ACE load balancers as of Fall 2015. Cisco has executed on the end-of-life, end-of-service, and end-of-support plans for their Cisco ACE appliances. Enterprises that currently use Cisco ACE for their load balancing needs have been strongly encouraged to search for an alternative before time runs out and find a solution that will prepare them for the modern enterprise requirements.
