AVI LoadBalancing

Delivering highly available and secure applications.

With VMware Avi, evoila is replacing rigid hardware load balancers with a software-defined platform. Scalable, self-service-enabled, and natively integrated into VCF.

Application delivery without hardware constraints

Hardware load balancers are expensive, inflexible, and operationally complex, and they do not scale with modern application environments. VMware Avi solves this problem with a fully software-defined approach:

L4/L7 load balancing, SSL termination, web application firewall, GSLB, and Kubernetes Ingress Controller on a unified platfor, without dedicated appliances. evoila implements Avi as a native component of VCF, empowering application teams with true self-service capabilities.

Business benefits at a glance:

  • Cost reduction: Replacing expensive hardware load balancers with a software-defined platform without appliance overhead
  • Agility: Self-service capability for application teams without dependence on the network team
  • High availability: GSLB and intelligent load balancing ensure application availability even during site outages

Hardware load balancers as a barrier to growth

Traditional hardware load balancers were built for a world where applications were rarely deployed and rarely changed. In modern environments, they pose a structural problem: every new application, every SSL configuration, and every load-balancing rule requires manual intervention by specialised personnel, resulting in long turnaround times and a high risk of errors.

At the same time, the application landscape is undergoing fundamental change: Kubernetes workloads require dynamic ingress controllers, multi-site architectures demand intelligent GSLB, and security teams require WAF integration directly within the load-balancing path. Hardware appliances can hardly meet these requirements cost-effectively. They do not scale in either configuration or performance without significant investment.

The VCF rollout highlights the need for action: Those who do not implement Avi as a native component of the platform lose integration density and continue to operate an infrastructure silo that structurally prevents automation and self-service.

Consequences of inaction

Every day an application team waits on a network ticket is a day your delivery pipeline slows down. Organisations that carry legacy hardware load balancers into a VCF environment are not just carrying technical debt. They are building a structural barrier against automation, self-service, and competitive speed.

The Challenge

Why hardware load balancers become a liability

Traditional load balancing infrastructure was designed for stability, not speed. The more dynamic your application landscape becomes, the more it works against you.

Manual Config, Maximum Delay

Every new application requires hand-crafted configuration by a specialist. That creates ticket queues, approval cycles, and slow releases that frustrate development teams.

CAPEX Without Ceiling

Scaling hardware load balancers means buying more hardware. Licences, rack space, power, cooling. The investment never stops, and the flexibility never arrives.

Kubernetes Left Without Support

Traditional appliances have no native understanding of Kubernetes. Ingress control, dynamic virtual service creation, and certificate lifecycle management require workarounds that break under load.

Visibility Gaps at Application Level

Hardware appliances report on connections, not applications. Without L7-native analytics, operations teams cannot tell whether an application is slow or simply overwhelmed.

Multi-Site Costs That Don’t Scale

Traditional load balancers require dedicated hardware per site for GSLB functionality. The cost model makes multi-site high availability economically unviable for all but the largest environments.

The good news: VMware Avi solves all of this without requiring you to redesign your network from scratch

evoila migrates existing configurations in stages, with zero downtime and full self-service capability from day one.

Our Solution

Avi as a software-defined delivery platform

From Appliance to Platform

When implementing Avi, evoila follows a structured migration approach: Existing hardware load balancers are analysed, configurations are migrated, and the transition is carried out in stages without compromising application availability. At the same time, self-service capabilities and automation integration are factored in from the very beginning.

L4/L7 Load Balancing Design & Implementation

Design and implementation of software-based load balancing at Layers 4 and 7, featuring virtual services, health monitoring, session persistence, and intelligent routing algorithms, natively integrated into the VCF network architecture.

SSL Termination & Certificate Management:

Configuration of centralised SSL/TLS termination with integrated certificate management, for secure application delivery without distributed certificate management at the application level.

Web Application Firewall (WAF)

Integration of the Avi WAF for application-level protection against OWASP Top 10 attacks, SQL injection, cross-site scripting, and other threat patterns—directly in the load balancing path, without a separate appliance.

GSLB – Global Server Load Balancing

Setup of GSLB configurations for multi-site environments—with health-based DNS routing, geographic load balancing, and automatic failover in the event of site failure.

Kubernetes Ingress Controller Integration

Avi as a native Ingress Controller for VKS and Kubernetes environments, with dynamic virtual service creation, automatic certificate management, and full lifecycle integration.

Self-Service & Automation Integration

Connecting Avi to VCF Automation so that application teams can independently and compliantly procure load balancer resources via the service catalog.

Tech-Deep-Dive

The architecture behind IT

Avi Control Plane & Service Engines

The Avi architecture consistently separates the control plane and the data plane: The Avi Controller handles central configuration, analytics, and lifecycle management—as a highly available cluster deployment integrated into VCF. The Service Engines handle the actual data path: They are dynamically provisioned as VMs, scale automatically with traffic volume, and are orchestrated by the controller. evoila scales both layers based on specific performance and availability requirements.

L7 Intelligence: More Than Just Load Balancing

Avi operates natively at Layer 7—enabling content-based routing, HTTP header manipulation, cookie-based session persistence, and application-specific health checks that verify the actual application status, not just the TCP connection. Combined with the integrated WAF, this provides a complete Application Delivery Controller function without the need for separate products.

Analytics & Visibility Engine

Avi features a built-in analytics engine that provides complete visibility into application performance, latency distribution, error rates, and security events—by virtual service, by client, and by backend pool. evoila configures dashboards and alert thresholds that enable operations teams to proactively monitor applications without additional APM tools.

GSLB Architecture for Multi-Site

VMware Avi GSLB implements DNS-based global load balancing with active health monitoring of all site endpoints. In the event of a failover, DNS resolution is automatically redirected to available sites—with configurable TTL values and persistence mechanisms. evoila designs GSLB topologies for active-active and active-passive scenarios and integrates them into existing DNS infrastructures.

Kubernetes-Integration: Avi as AKO

In Kubernetes environments, Avi acts as a native ingress controller via the AVI Kubernetes Operator (AKO). AKO automatically translates Kubernetes ingress and service objects into Avi virtual services, dynamically and without manual intervention. This gives application teams full self-service control over load balancing and SSL termination directly via Kubernetes-native manifests.
