How to Migrate from Brocade ADC to SKUDONET ADC

Migrate from Brocade ADC to SKUDONET ADC. Overview

Brocade ADX is part of Broadcom Inc products and provides load balancing, traffic management, and security for web applications.

Like most technologies, Brocade ADX has some drawbacks and limitations that the SKUDONET TEAM has analyzed and brought forth solutions for. Some of these drawbacks include:

  1. Complexity: The setup and configuration of Brocade ADX can be complex, especially for users new to networking and load-balancing. This makes it difficult for organizations to get up and running quickly and efficiently.
  2. Scalability: While Brocade ADX is designed to handle high traffic amounts, scaling the solution to meet increasing demands can be challenging, especially in highly dynamic environments.

We gathered more drawbacks, and SKUDONET Team is working resiliently to use all suggestions to improve SKUDONET ADC. However, some of these limitations may depend on your specific deployment scenario.

Prerequisites. Broadcom’s Traffic Manager

To migrate from Brocade ADC to SKUDONET ADC, ensure you accomplish the following first;

  1. Install an instance of SKUDONET on your PC, bare-metal, virtual environment, or at least have an active ZVNcloud account. For on-premise deployment, Request an evaluation.
  2. Ensure you access the Web User interface by following this quick Installation guide.
  3. You must be an active user of Broadcom’s Brocade ADX or virtual Traffic Manager and be familiar with the concepts we will discuss in the section below.
  4. Ensure that you create a virtual server in the SKUDONET load balancer. Here is a quick guide: Layer 4 and Layer 7 Virtual Server Configuration.

Basic Concepts

Service: A program to which clients from the web request access to its resources. This service could be SMTP, HTTP, HTTPS, SSH, RSYSLOG, etc. SKUDONET Services are categorized as Local or Remote. Access and configure services through System >> Services.

Pool: A collection of Nodes delivering the same service and processing requests from the web. With SKUDONET, one may configure a pool through the Backends section in a Farm >> services.

Traffic IP Groups: This is a virtual IP address that listens for external traffic from the Internet. With SKUDONET, create a virtual Interface, then select that IP address as the Virtual IP after creating a Farm.

Virtual Servers: This is the front-facing section of the Brocade ADX. One can assign a port number and a Virtual IP using Traffic IP Group. A virtual server in SKUDONET is the same as a Farm.

Nodes: A node is a member of a pool. It is a backend server placed behind a reverse proxy. It processes user requests and stores their data. A node is the same as a Backend in SKUDONET.

Health Monitor: These programs monitor the availability of backend servers and their services. Health monitors are the same as a Farmguardian in SKUDONET.

SSL Decryption: This functionality enables the load balancer or reverse-proxy to perform SSL Termination on encrypted traffic. Enable SSL Termination/Offloading on an HTTPS profile in SKUDONET by selecting the Cipher as “SSL offloading”.

Service Protection classes: These are settings one specifies to protect the service against a flood of malicious attacks, such as all forms of DDoS. To configure security in SKUDONET, Access the IPDS module.

Activity: This functionality helps an admin keep track of the processes on the ADC. One may visualize all the information through graphs, charts, etc. With SKUDONET, one may view this information through the Dashboard and view statistics and graphs through Monitoring >> Graphs and Monitoring >> Stats, respectively.

Cluster: Used when there is a need to maintain high availability of services even if one of the nodes within a pool fails. With SKUDONET, one may configure a cluster by accessing System >> Cluster.

Example configurations: High Availability

High Availability (HA) ensures that a certain level of operational performance and quality of service is met, despite failures of certain system components. One may achieve HA by setting up multiple redundant components, such as reverse proxies, networks, and storage systems, that provide alternative paths for data to flow if one or more components fail. Each user must have a continued service in the event of component failures.

In this section, we will describe how one may configure High availability in SKUDONET based on configurations of Brocade vTM. We will describe the configurations from either side to make an easier transition.

Brocade configurations

To configure a cluster in Brocade through the Web User Interface, we will take the route of the cluster configurations Wizard. Ensure that you have at least two active nodes with the same configurations.


    1. On the menu, click on the Wizard drop-down menu.
    2. Select the option Join a cluster. A separate window will show up.

Migrate from Brocade ADC to SKUDONET ADC

    1. There are 2 options. Select existing cluster and Manually specify host/port. For these configurations, “Manually specify the host/port” and click Next.

Migrate from Brocade ADC to SKUDONET ADC

    1. Enter the Hostname and Port for the remote Node and click Next


  1. As the Admin, verify the SHA-1 fingerprint by clicking the checkbox beside it.
  2. Enter a username and password for the remote Node and click Next to continue.
  3. Confirm with your settings and click Finish to join the cluster.

SKUDONET configurations

SKUDONET implements HA through clusters. Ensure you have 2 ADCs of the same type and version. Ensure both nodes have similar settings and are active.


    1. Click System >> Cluster.
    2. Select the Local IP address. This will be the IP of the appliance you’re currently using.
    3. Enter the Remote IP address of the other active Node.

Migrate from Brocade ADC to SKUDONET ADC

    1. Enter the Remote Node Password.
    2. Reenter to Confirm remote node password.
    3. Click the Apply button to save the configurations.
    4. During a failover, you might wish the load balancing services to return to the Master when it becomes fully functional. Click the Edit button with the pencil icon.


  1. Click on the Failback* option to configure the Master.
  2. You may specify the Check Intervals for each node heartbeat.
  3. Click the Apply button to save the configurations.

Example configurations: Global Load Balancing

Global Server Load Balancing is a technique that distributes network traffic across multiple servers in different geographic locations. It helps to ensure the high availability and reliability of applications by automatically redirecting traffic to alternate servers in the event of a failure. Admins may configure Global load balancers to serve in either Active-Active mode for fast service delivery or Active-Passive mode for redundancy.

In this section, we will configure Global Server Load Balancing in SKUDONET Based on Brocade vTM configurations.

Brocade configurations

For the brocade traffic manager to perform global load balancing, you must; Define the GLB locations, Create Service Monitors for each of your GLB Locations, create a GLB service to manage DNS queries, configure a Pool for your backend DNS Servers, and create a DNS virtual Server that listens for DNS queries.


Defining GLB Locations

  1. Click Catalogs >> Locations.
  2. Enter a Name to Identify the location in the Create new GLB Location section.
  3. Select the Type “GLB”.
  4. Click Add Location to the GLB Location you created. You will then access the location edit page.
  5. Choose the Position of the GLB from the drop-down that will be shown.
  6. Click Update to save the changes.

Creating a service Monitor

  1. Click Catalogs >> Monitors.
  2. Within the section Create new monitor, enter the Name, Type, and Scope of the Monitor.
  3. Click the Create Monitor button. You’ll get access to the edit page.

  3. Click the Create Virtual Server button. You will have access to the edit page.
  4. Click GLB Services, and access its edit page.
  5. Within the section Add new GLB Service, select from the drop-down menu a GLB service you created earlier.
  6. Set the value for Enabled to “Yes” on the Virtual server edit page.

SKUDONET Configurations

For SKUDONET ADC to perform global load balancing, you must; Create a GSLB Farm, Add a Service, Add Backends, Configure DNS Zones, and Add DNS Security.
