Myth Busters: Application Load Balancing is Complex

The architecture that most legacy load balancers are built on is from the pre-virtualization, client/server days. This architecture is monolithic, multiple tools are needed to provision and monitor, and self-service and automation are simply not possible. Avi Networks has built the first software defined application services platform based on an architecture with a centralized control plane (called the Avi Controller) and a distributed data plane consisting of micro load balancers (called Avi Service Engines). This SDN like architecture creates an intelligent service fabric that can dynamically scale up or down and makes managing thousands of applications incredibly simple.  



All interactions with the Avi Controller are through native REST APIs. The Avi UI and CLI are themselves built on top of these REST APIs. This single point of automation via REST APIs enables simplified policy-driven configuration so that end users don’t need to be experts. DevOps and orchestration tools like CFEngine, Chef, Puppet and Salt are natively supported making custom integration easy. All of these capabilities broaden the applicability of services to applications that enterprises have not previously considered because it was just too cumbersome or too expensive. With Avi Networks, enterprises can choose to apply ADC capabilities on per app basis if they so choose.  The graphic below shows our per app elastic application services with the rest of the infrastructure stack: 



Avi Cloud Connectors enable seamless integration with VMware, OpenStack, and Public Cloud (AWS) environments automating services for multiple clouds. Avi Cloud Connectors enable hybrid cloud with a single point of control and visibility for both on-premises and cloud based applications.


Avi Networks empowers tenants and application developers to provision, monitor, optimize, and secure their applications within the policy that administrators have set. DevOps teams are able to spin up their load balancing instances in less than a minute where legacy solutions could take weeks. This flexibility not only leads to faster deployment times but provides the ability to scale users, applications, and capacity without adding complexity.


The ADC space has been deafeningly silent on innovation for a long time. The modern architecture that Avi Networks has delivered to the ADC market is compelling to enterprises from both an automation and self-service perspective. A Fortune 100 financial institution recently chose Avi Networks for these reasons:

  • 1200+ load balancers with centralized policy and automated lifecycle management

  • Ability to autoscale load balancers predictively based on real-time traffic patterns

  • 100% REST API that empowered their lines of business with self-service IT

Yes, load balancing thousands of applications can be simplified and many of our customers are thrilled to have an innovative way to accomplish this task. We will be thrilled to tell you how this works - join us for our weekly “demonar” on Tuesdays at 11:00 am PST.
