The roadmap to federated Cloud

UK NGS Cloud Activities (2010 – 2012)
• NGS Agile Deployment Environments
EPSRC funded, 2 years
• Staff:
– David Wallom (OeRC, Oxford);
– David Fergusson (NeSC, Edinburgh);
– Steve Thorn (NeSC, Edinburgh);
– Matteo Turilli (OeRC, Oxford).
• Goals:
– EC2 compatible, open source solution;
– Small physical systems physically distributed
– development of a dedicated pool of images, supporting both end
user and NGS requirements such as training;
– collecting data about feasibility, costs, stability;
– identify use cases and gather further requirements.

NGS Cloud Usage
• >120 registered users: uptake has been very fast
and users stayed engaged throughout the whole
testing period;
• 26 institutions: 23 HEI both universities and colleges,
3 companies;
• 30 projects;
• 10 research areas.

Exemplar Case Studies
• Evolutionary Genomics: “analysis and Information management of
Next Generation Sequencing (NGS) of Genomic data poses many
challenges in terms of time and size. We are exploring the translation of
high quality NGS scientific analysis pipelines to make best use of Cloud
infrastructure”;
• Geospatial Science: “geospatial data is a mix of raster and vector data.
As rasterizing is CPU-hungry process, and all maps displayed on the
screen of the final user are rasters, it is more efficient to do the process on
the server side. I am investigating how this process can be dispersed
across many, if not unlimited instances in a cloud”;
• Agent-based modelling of crime: “at the moment I have a tomcat
server that hosts some web services used to run social simulation model, it
needs access to the file system to run fortran scripts, create files etc. There
are loads of problems with running our own server at uni and I think a
virtual machine that I could have control over would be much better”.

Flexible Services for the Support of Research (FleSSR)
6 Partners
• Academic and industrial;
• 3 cloud infrastructures.
Goals
Building federated cloud infrastructure,
extending the use of UK NGS central services
with cloud brokering and accounting.
Use cases
• Multi Platform Software Development;
• On demand Research data storage.

FleSSR Infrastructure
• Local/Global: services depends either on local or global
access. Cloud brokering is not mandatory for AWS-like
service access;
• Multiple identities: every user may have multiple identities,
both local and global;
• Only personal identities: group identities are not
implemented. The management of every single identity is
left to the legally responsible user;
• Multiple AA technologies: AA may differ depending on
local and global policies/technologies;
• Multiple accounting: every single identity is accounted for
its usage. Every individual may get multiple invoices.

FleSSR Output
Code
• Instance configuration and build manager: Perl command line
utility + Java client utilising the Zeel/I API;
• Personal EBS volume manager: web-based, Java client for EBS
volumes handling + tailored VM image with multiple data interfaces
(SFTP, WebDAV, GlusterFS, rsync, ssh);
• Eucalyptus open-source accounting system: Perl aggregators
and parsers for standard eucalyptus open-source log files +
MySQL accounting database + PHP accounting client.
Use cases
• SKA community testing of Use case;
• Institutional ICT team testing WEB-DAV, GridFTP & GlusterFS
solution as Use case 2.

Federated Cloud solution
The Federated Cloud Solution is providing access to digital
resources on a flexible environment, using common standards to
support data- and computing intensive experiments:
• a set of independent cloud services presented coherently as a
single system using common standards.
• allows the user to choose freely among a broader range of service
providers
• allow use of applications already developed by people within their
own community whom they trust, and from other communities who
have an independent badge of quality.
Target groups:
• individual researchers
• larger research communities or groups
25

Principles of Federation
• Standards and validation: Recommended and
common open standards for the interfaces and images
– OCCI, CDMI, OVF, GLUE2, AAI
• Resource integration: Cloud Computing to be
integrated into the existing production infrastructure.
• Heterogeneous implementation: no mandate on the
cloud technology.
• Provider agnosticism: the only condition to federate
resources is to expose the chosen interfaces and
services.

Conclusions
• Utilisation of virtual infrastructure is the only scalable method to support large number
of disparate user communities with widely differing application models,
• Federation as robust and scalable model of national/European cloud infrastructure for
research, though part of an ecosystem of e-infrastructure not e-infrastructure alone.
• Federation is only possible by the availability of open standards,
• Successful pilot tests of multiple prototypes of cloud infrastructure allowed a quicker
development of the final model for EGI,
• EGI Federated Cloud is attracting new communities belonging to various scientific
domains
– 26 communities and 59 use cases currently supported, 5 from commercial organisations
• Paving the way for a global federated cloud marketplace led through European
Innovation
– Established best practice
– Illustrating leadership
– Open standards, open technology
– Open membership, open processes
– Open competition
• Oxford and OeRC has led this activity from its inception in 2010 through to now
