Based on Webinar content / known FAQs specify a number of sub-topics, like

  • Costs
    • An estimate for the cost for a basic/medium-sized Delft-FEWS system in the cloud would de around 12k€- 15k€ .
      This is an estimate and will differ per Delft-FEWS system. Important cost variables are:
      • data (size and egress)
      • size of the whole Delft-FEWS system (sizing of the VM's, number of the VM's, number of Delft-FEWS components per VM)
      • the number of users (depending on the location of the Operator client; in the cloud v.s. on-premise)
      • requirements regarding redundancy, High Availability, Disaster Recovery, performance 
    • Data ingress and egress (egress exits the cloud and ingress enters the cloud)
      Ingress and data traffic in the cloud environment is often free of cost.
      Egress however is not free. The egress cost depend on the type of connection and on the amount of egress data.
      Some examples/comparisons for Azure can be found on this webpage: How to calculate the right Azure outbound capacity and choose the best egress option
    • Type and number of machines
      The price difference between for example a 32GB virtual machine and two 16GB virtual machines (VM) is quite the same. However, depending on your requirements, each separate VM requires additional and individual services like for example back-up and security. 
    • Data storage
      Data can be stored in different cloud solutions each with it's own price and functionalities. Depending on your requirements you can add managed disks to your machine or a dedicated storage solution like Azure files or Blob storage solutions
    • Managed v.s unmanaged
      Cloud providers offer managed services like for example a managed database. The price for a managed solution is higher than an unmanaged solution. However, a managed solution requires a lot less of your own IT-staffing hours regarding managing the system.
