This is draft of procedure and related work instructions for User, Provider and Broker


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).


Resource Allocation Process activities:

  1. Pool creation - P : Creation of Resource Pool instruction (for Resource Providers)
  2. User Request creation - C : Creation of Request instruction (for Customers)
  3. User Request validation - C and B
  4. OLA creation based on pool matching - B
  5. OLA (re)negotiation - P and B
  6. OLA confirmation/rejection  - P
  7. SLA creation/updating  - B
  8. SLA negotiation step - B and C
  9. SLA confirmation/signing - C


Resource Allocation Procedure (draft)

Request validation (non blocking 3 days, executed in parallel)

Broker checks that Customer has valid x.509 certificate supported by EGI.eu. (e.g. EGI EUGridPMA organization). If not, Broker suggest Customer to obtain certificate.

Broker checks that Customer  is member of VO. If not, Broker points Customer to documentation on creation of new Virtual Organization (VO): https://wiki.egi.eu/wiki/PROC14

Broker notifies EGI.eu (support@egi.eu Gergely Sipos). Veto to request(with explanations) should be e-mailed to resource-allocation-support at mailman.egi.eu as soon as possible, no more than 3 days. This description will be sent to Customer.


Request vs resource pool matching (executed in parallel)

Broker matches resources. Broker choose pool according to https://wiki.egi.eu/wiki/Resource_Pool scenario (Free hands, Right to revoke, Negotiated)


SLA/OLA negotiations

Broker checks wheter there was EGI.eu veto announced. If yes, Request is Rejected and Customer notified about reason.

If not, Broker sends to Customer SLA proposal.

Customer and Broker negotiate values of the metrics. If needed Broker and Provider negotiate related OLA.

If agreement is reached, Customer signes SLA and the offer is binding for both parties.

Binding OLA configured on site (VO on site, resource allocation)

Resource Provider configures resources according to the binding Request.
