CCRC'08 Service Map

Overview

The CCRC'08 ServiceMap is a tool for displaying different aspects of the service readiness of the WLCG Computing Infrastructure. the list of services are those provided by the WLCG experiments.

There are currently three different view components:

  • Service Readiness - An evaluation of the service against a list of common deployment questions
  • Service Availability - Availability of a service
  • Experiment supplied data - this is data provided by the experiment frameworks to show their view of different aspects of the service e.g. reliability, throughput, usage, etc...

Components

Service Readiness

The Service Readiness map is designed to show how ready a service by looking at the maturity of the software, the service in general in terms of documentation, process and procedures and the specific deployment at a site. Each question is scored between 0 and 1 (or - if not relevant), and the overall readiness is the average of the individual questions. The questions are in three sections, each dealing with a different aspect:
  • Software Readiness
  • Service Readiness
  • Site Readiness

Software Readiness

Question Comments Sorted descending
High-level description of service available? with architecture diagam
Code released and packaged correctly? Repository + Tagging process, rpms/tarballs
Middleware dependencies and versions defined? OS deps, M/W deps, platforms supported
Certification process exists?  
Admin Guides available? Installation, monitoring, problem determination
Automatic Configuration code exists? e.g. Yaim, NCM, …

Service Readiness

Question Comments
Disk, CPU, Database, Network requirements defined?  
Monitoring criteria described?  
Problem determination procedure documented  
Support chain defined (2nd/3rd level)?  
Backup/restore procedure defined?  

Site Readiness

Question Comments
Suitable hardware used  
Monitoring implemented  
Test environment exists  
Problem determination procedure implemented  
Automatic configuration implemented  
Backup procedures implemented and tested  

Service Availability

The Service Availability map shows availability for the VO Critical services.
