Terms

Request – Service Level Agreement (SLA)

OLA – Operations Level Agreement – between EGI.eu and Resource Provieder

SLA Sections – Service Level Agreement Sections related to OLA with given Resource Provider

Customer - person signing SLA with Resource Provider

User - person using resources on base of binding SLA (could be Customer itself)

Introduction

The effective usage of IT resources requires from Customers and Resource Provider reaching agreement on how much resources, with some specific requirements will be available to User at specific time period.

In heterogeneous IT environment it is difficult for Customers to find matching resources and for Resource Providers to manage their IT capacity.

The Resource Allocation process, if possible,  facilitates reaching agreement between Customers and Resource Providers.

Starting point are:

  • set of Resource Pools defined by Resource Providers describing in common metrics resources they are willing to deliver to Users
  • set of Customers expectations (Request) describing in common metrics resources they are willing to use

As a result of the process, if the Request was agreed by all parties, there is binding SLA signed, that is basis for resource configuration, allocation usage, support and allocation accounting.

In case there were not matched Requests, the output of the process is report to EGI.eu allowing to manage Pool Capacity (add new resources).
