Integrating NSX ALB With VMware Cloud Director. Know the WHY!

In today’s digital landscape, the demand for scalable and secure cloud infrastructure is at an all-time high. VMware Cloud Director (VCD) is a leading cloud management platform that enables service providers to deliver multi-tenant virtual data centers to their customers. NSX Advanced Load Balancer (NSX ALB), formerly known as Avi Networks, is a powerful application delivery controller that offers advanced load balancing and application delivery capabilities. In this blog, we will explore the integration of NSX ALB with VCD and discuss the benefits it brings to cloud environments.

Understanding VMware Cloud Director

VMware Cloud Director (VCD) is a powerful cloud management platform designed for service providers to deliver infrastructure-as-a-service (IaaS) offerings to their customers. It enables the creation, management, and provisioning of virtual data centers, allowing service providers to offer scalable and customizable cloud environments to their clients.

VCD provides a multi-tenant architecture, allowing service providers to serve multiple customers while maintaining isolation between their resources. It abstracts the underlying infrastructure and provides a self-service portal through which customers can manage their virtual data centers, deploy and manage virtual machines (VMs), storage, networking, and other cloud resources.

Understanding NSX ALB

NSX ALB (NSX Advanced Load Balancer) is a software-defined application delivery controller solution offered by VMware. It provides advanced load balancing, traffic management, and application delivery services for modern applications deployed in cloud and data center environments. Formerly known as Avi Networks, NSX ALB offers a distributed architecture, allowing it to scale horizontally and handle high traffic volumes efficiently. NSX ALB offers advanced load balancing algorithms, SSL/TLS termination, content switching, and application security features, making it an ideal solution for modern cloud-based applications.

WHY NSX ALB and not Legacy Load Balancers?

Legacy Load Balancers   VMware NSX Advanced Load Balancer  
Not Designed for Cloud Operating Model: Manual configs of each appliance, Lacks elasticity, Complex. Built for Cloud Operating Model: Zero tickets, Self Service automation, Elastic auto-scale, Software defined.  
Highly Over-Provisioned: Less than 15% utilization, No active-active.   Optimal Capacity Management: High Utilization, zero touch auto-scale, Active-Active.  
Hard to Troubleshoot: Finger pointing among server, network, and app teams.   Easy to Troubleshoot: Stop the blame game with rich and contextual analytics.  
Not Integrated with VMware Stacks: Complex to deploy, lacks unified automation & visibility. Integrated with VMware Stacks: Validated design; Unified automation workflows & visibility.  

Why NSX ALB and not Legacy Load Balancers?

The Benefit of NSX ALB as a Solution

By leveraging NSX ALB, cloud providers can deliver highly available, scalable, and secure application services to their customers. It empowers cloud providers with advanced load balancing capabilities, simplifies operations, and integrates seamlessly with VMware’s ecosystem, making it a valuable addition to their cloud infrastructure offerings.

Cloud providers can benefit from using NSX ALB (NSX Advanced Load Balancer) for several reasons:

  • Advanced Load Balancing Capabilities
  • Scalability and Elasticity
  • Application Security
  • Simplified Operations and Management
  • Integration with VMware Ecosystem
  • Automation and DevOps Support
  • Visibility and Analytics
  • Vendor Support and Expertise

The Benefits of Integrating NSX ALB with VCD

Enhanced Application Performance: By integrating NSX ALB with VCD, service providers can leverage the advanced load balancing capabilities of NSX ALB to distribute traffic intelligently across multiple application instances. This ensures optimal performance and availability of applications, improving the user experience.

  • Scalability and Elasticity: NSX ALB’s distributed architecture enables automatic scaling based on demand. When integrated with VCD, it can dynamically scale the load balancer resources to accommodate changing traffic patterns, allowing service providers to handle sudden surges in application load without manual intervention.
  • Simplified Operations: The integration of NSX ALB with VCD brings operational efficiencies by providing a single pane of glass for managing the entire application delivery infrastructure. Service providers can leverage VCD’s familiar interface to configure and monitor load balancing services, eliminating the need for separate management consoles.

Opportunity for Cloud Services Providers

What’s in it for me?

Create New Revenue Stream: Creating a new revenue stream is a crucial objective for businesses seeking growth and sustainability. It involves identifying and capitalizing on opportunities to generate additional income beyond existing products or services.

  • Customers Spend Significantly on Load Balancing & Spend is Growing
  • >$3B Competitive Install Base Ready for Refresh w/ Low Barrier to Switch
  • Huge Land and Expand Opportunity
  • Easier Cross-Sell in Same Account
  • Monetize NSX ALB Instead of “Bring Your Own” Load Balancer
  • Differentiate with Managed Services

Implementing NSX ALB leads to a substantial boost in annual revenue, averaging over $13 million, along with an impressive 27% surge in application developers’ productivity. When it comes to Day 2 operations, we excel in the market, achieving a remarkable 90% faster scaling to capacity and experiencing 54% fewer outages in the production environment. Moreover, NSX ALB significantly reduces operational costs, with a return on investment realized in approximately six months and an overall 43% reduction in operational expenses.
