Question

How much capacity should I buy?

Answer

The capacity needed would depend on each customer use case and various evaluation parameters. Evaluation parameters include the number of network elements, number of topologies to run, the duration of the project, and so forth. Use the Junosphere Capacity Calculator to find the most cost-effective SKU for individual usage available in the Junosphere Toolbox.

 

There are two types of capacity you can order:

 

  • Regular capacity, which is based on a specific number of VM units that are ordered on an as-needed basis and used through reservations.
  • Annual plan capacity, which provides a fixed number of VM units for a full year. Topologies can be run as frequently or rarely as needed. There is no need for a reservation and no need to purchase additional capacity. This plan also provides additional overflow capacity of a fixed VM unit amount.

    In the Annual Plan, overflow capacity is supplemental regular capacity that allows a customer to go beyond the daily limit of the Annual Plan for a fixed amount of time. For example, the 100 VM unit Annual Plan has 2000 VM units of overflow capacity. This allows you to run a topology of 200 VM units (100 VM units included in the Annual Plan and 100 VM units from the overflow capacity) for 20 days, 150 VM units for 40 days, 110 VM units for 200 days, and so on. It is expended on the same pay-per-use basis as other regular Lab and Classroom (non-annual plan) capacity.
