Sizing

Overview

Correct sizing is crucial to ensuring an optimal user experience. As an administrator, it is imperative to adhere to established guidelines to provide all users with the best possible user experience (UX).

Factors Influencing Sizing

A strong sizing plan helps calculate your infrastructural needs. Some of the factors influencing sizing are broadly listed here.

  1. End-user: To create a sizing plan, determine the total number of end users and the maximum concurrent users. This information will help accurately calculate the required Disk size, vCPUs, and RAM.
  2. VDI per User: These sizing guidelines assume each user can access one VDI. To ensure optimal UX, contact support@accops.com if there are any deviations from this assumption or if you have any special needs.

  3. User Access Mode: The capacity planning will be affected by your user’s access modes. There are two modes of access:

    1. Web Browser: In other words, HyLite Portal-based access. When the user accesses the resources through a web browser, the HySecure Gateway is responsible for most of the processing; hence, the workload is higher.
    2. Native Client: In other words, HySecure/Workspace/ clients are installed on endpoint devices like laptops and mobiles. When this access mode is chosen, the endpoints handle most of the processing, reducing the workload on the HySecure Gateway.

HySecure Sizing Guidelines

This section gives details of the terminologies used and the HySecure sizing.

Terminologies Explained

Let us look at the terminologies used in the sizing to understand better.

  1. Concurrent User Count: Number of simultaneous users logged into the HySecure cluster.

  2. Nodes: There are three types of nodes:

    1. Active Nodes:

      • The Active node hosts the database in active mode and is responsible for load balancing.
      • Apart from database role and load balancing, this node also serves the user requests for HySecure.

    2. Standby Nodes:

      • The Standby node hosts the database and load balancer in passive mode. If the Active node goes down, it will take on the role of database and load balancer.
      • Apart from the database role and load balancing in passive mode, this node also serves the user requests for HySecure.

    3. Real Nodes:

      • The Real node does not have a database and load balancer; it depends on the active node for policy configuration.
      • This node is purely used to serve user requests for HySecure.

  3. vCPU per Node: The required vCPU per node.

  4. RAM per Node: The required RAM in GB per node.
  5. Storage per Node: The required storage space in GB per node.

  6. Load Balancer: There can be two types of load balancers.

    • Built-in: A Built-in load balancer means this deployment does not need a separate load balancer; the HySecure Active node will act as a load balancer.
    • External: An external load balancer will be required in larger deployments. HySecure Active and Standby nodes will only act as a database and will not be used for load balancing and serving the user request.

  7. HySecure Config Node: The Config Node has two primary functions: maintaining the database and user load balancing.

    • Built-in: When we say built-in node, in that case, Active and Standby nodes will act as databases, perform load balancing, and handle user requests.
    • Additional: When we say "Additional," the Active and Standby nodes will only act as a database; an external load balancer will be used. These nodes will also not serve the user request.
