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

In today’s digital landscape, the demand for scalable and secure cloud infrastructure has never been higher. 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 high-performance application delivery controller that provides 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 deployment of virtual data centers and enables service providers to offer scalable and customizable cloud environments to their customers.

VCD provides a multi-tenant architecture that allows 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, provision 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 from VMware. It provides advanced load balancing, traffic management and application delivery services for modern applications deployed in cloud and data center environments. NSX ALB, formerly known as Avi Networks, provides a distributed architecture that enables horizontal scaling and efficient handling of high traffic volumes. 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 Balancer?

Older load balancers VMware NSX Advanced Load Balancer
Not designed for the cloud operating model: Manual configurations of each appliance, lack of elasticity, complex. Built for the cloud operating model: ticket-free, self-service automation, elastic auto-scaling, software-defined.
Highly disproportionate: Less than 15% utilization, no active-active. Optimal capacity management: High utilization, touch-free auto-scaling, active-active.
Hard to fix: blame game between server, network, and app teams. Easy troubleshooting: Stop the blame game with rich, contextual analysis.
Not integrated with VMware Stacks: Complex to deploy, lacks unified automation and visibility. Integrated with VMware Stacks: Validated Design; Unified automation workflows and transparency.
Why NSX ALB and not Legacy Load Balancer?

The benefits of NSX ALB as a solution

By leveraging NSX ALB, cloud providers can provide highly available, scalable, and secure application services to their customers. It provides cloud providers with advanced load balancing capabilities, simplifies operations, and integrates seamlessly with the VMware 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 the VMware ecosystem
  • Automation and DevOps support
  • Visibility and analysis
  • Vendor support and expertise

The benefits of integrating NSX ALB with VCD

Improved application performance: By integrating NSX ALB with VCD, service providers can leverage NSX ALB’s advanced load balancing capabilities to intelligently distribute traffic across multiple application instances. This ensures optimal application performance and availability and improves the user experience.

  • Scalability and Elasticity: NSX ALB’s distributed architecture enables automatic scaling as needed. When integrated with VCD, it can dynamically scale load balancer resources to accommodate changing traffic patterns, allowing service providers to handle sudden increases in application load without manual intervention.
  • Simplified operations: The integration of NSX ALB with VCD ensures operational efficiency 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 balancers, eliminating the need for separate management consoles.

Opportunity for cloud service providers

What’s in it for me?

Create a new revenue stream: Creating a new revenue stream is a critical goal for companies seeking growth and sustainability. This involves identifying and exploiting opportunities to generate additional revenue beyond existing products or services.

  • Customers are spending significantly on load balancing and expenses are increasing
  • Competitive install base valued at over $3 billion, ready to upgrade with low barrier to transition
  • Huge land and expansion possibilities
  • Easier to cross-sell in the same account
  • Monetize NSX ALB instead of bringing your own load balancer
  • Differentiate yourself with managed services

Implementing NSX ALB results in a significant increase in annual revenue, averaging over $13 million, as well as an impressive 27% increase in application developer productivity. When it comes to day two operations, we stand out in the market by achieving a remarkable 90% faster scaling to capacity and experiencing 54% fewer outages in the production environment. In addition, NSX ALB significantly reduces operating costs as the return on investment is achieved in approximately six months, reducing overall operating costs by 43%.
