Webscale organizations such as Facebook, Google, and other large cloud vendors have modernized their infrastructure with open source software and commodity hardware. Bringing such a Webscale IT approach to mainstream enterprises was hard because they lacked the tools for such a transformation.

Application Load Balancing vs. Appliance Load Balancing

avatar Chandra Sekar
Posted on Apr 6, 2016 4:55:42 PM

Humans are compulsive comparers. We have a natural propensity to view things in our day-to-day lives by setting them against each other. It helps us to choose the most desirable option, prevents us from getting ripped-off, or even fuels our drive to innovate and improve. Let me touch on that last benefit conferred by our urge to compare. Last week, my colleague Rob Duncan waxed eloquent about the characteristics of IT champions at many enterprises. These champions exemplify Gartner’s Mode 2 IT behaviors by innovating with new technologies and IT practices. They compare their status quo to choices that can position their organizations to better compete in their industries by compressing time-to-market, lowering costs, and improving their responsiveness to internal customers. So, we asked a few of our customer champions about comparisons that drove their decisions for application delivery and services and their choice of the Avi Vantage Platform. Across the board, a few common themes came up when they described how they were able to shift focus from the tactical, task-oriented handling of appliances to the much more strategic approach of managing applications.

Scaling Load Balancers | Myth Busters: Scaling Can Take Weeks

avatar Grant Swanson
Posted on Feb 12, 2016 9:20:53 AM

A common challenge that most enterprises are facing today is their ability to scale out applications. From many vendors of application services we often hear a lot of buzzwords like elasticity, autoscale, and cloud bursting but the fundamental problem of knowing the traffic or transaction threshold beyond which applications and their load balancers need to be scaled, still remains. You may be wondering how that can be possible considering all of the advances in technology over the past few years. The reason, it turns out is that load balancing appliances that promise those buzzwords are really not equipped to deliver those capabilities. They are built on proprietary hardware (not portable across environments) and while they sit in the data path, they do not have transaction analytics that enable them to make intelligent decisions on application performance. These legacy Application Delivery Controllers (ADCs) and load-balancing appliances are static and slow down operations.

Myth Busters: Load Balancers Need Specialized Hardware

avatar Grant Swanson
Posted on Jan 6, 2016 12:35:12 PM

The Application Delivery Controller (ADC) market is very competitive, where every vendor claims that they have a performance advantage. Most IT Pros who need high performance ADCs and Load Balancers start by looking at specialized hardware appliances in order to meet their requirements. Then performance testing for L4-L7 throughput takes place and folks quickly realize that as more features are turned on, the performance quickly degrades. Forward-looking ADC buyers are now starting to look at software solutions that can run on commodity x86 hardware and that offer better performance at a fraction of the cost of specialized hardware.

Load Balancing | Confessions of a Hardware ADC Salesman

avatar John Huang
Posted on Nov 23, 2015 10:35:01 AM

INTRODUCTION: I have helped enterprises “deliver” their applications for a long time. And somewhere in every conversation with a prospective customer I always asked, “What will your traffic be like in 3-5 years?” Yes, I was sincerely trying to size their network equipment to sell the right load balancers. But, I was also doing my company’s bidding to sell enterprises more gear than they would likely need. I was as guilty of doing it as any of my counterparts at competitive load balancing vendors. It was always good to play up the prospect’s optimism especially tech-heavy Silicon Valley. However, the traffic growth question asked by hardware ADC vendors is impossible to answer by mere mortals and most companies just capitulate and buy enough capacity for 4-5 years down the road. More often than not, when I revisited many of my customers in 12-24 months, I found that gear still running at single digit capacity. The tendency to oversell gear wasn’t an intentional desire to exploit customers, but was driven by the architectural limitations of an inelastic hardware model. Paying upfront for anticipated future growth has been an accepted norm in the IT industry for a long time. Disruptive forklift upgrades are par for the course in the IT world where nobody has a crystal ball for how traffic might outgrow existing equipment.

Load Balancer Provisioning | The 30-Second Load Balancer

avatar Ashish Shah
Posted on Sep 24, 2015 5:00:00 AM

When talking to customers, we often hear the term, "Self-service provisioning." The reason is that enterprises want non-networking experts to have the ability to use an Application Delivery Controller (ADC) without having to rely on a network administrator. The goal of these enterprises is to drive application deployment as fast as possible. If you have to create tickets to get a load balancer configured, it severely impacts the efficiency of application development and deployment. We were at a large multinational bank a couple of weeks ago and were astonished to find out that it takes about 27 days on average from the time an application developer requests a load balancer instance to the time the IT team actually delivers it. Imagine an AWS-like experience where any app developer can: Create a load balancer instance in less than 30 seconds Eliminate your network tickets and deploy your applications faster Give developers access to these network resources instantly.
