How ostrmn.com works

• Before we start you do your best to gather relevant information about your infrastructure:
  • What does your infrastructure do?
  • Can you provide documentation about your infrastructure?
  • Which service providers do you currently use?
  • Do you have all credentials to your systems available?
  • Is there a technical point of contact in your organisation?
• Free of charge: Allow ostrmn.com to have a look around your infrastructure in a 2-step process. Make arrangements to allow sufficient time for the second step.
  • In a first step, show where you currently are with your infrastracture. This usually involves a shared screen session. Credentials to your systems are not yet strictly necessary but might be helpful.
  • If you are ready to continue you would grant access to your systems in a technical sense. This second step helps to get an idea of the necessary steps to make your infrastructure maintainable in a standardised way.
• ostrmn.com will let you know about a possible course of action. This is free of charge. The aim is to create an environment where your infrastructure can be maintained in a standardised way and with a predictable price tag.
  • Maintaining your infrastructure in a standardised way is usually preceded by creating documentation or migrating your systems.
  • ostrmn.com keeps you independent. There will never be artificial barriers that prevent you from switching to another IT service provider.
• As soon as your infrastucture is in a state where it can be maintained in a standardised way the pricing example may apply.
