1 GRNET-4 Offering Cloud Services to the Greek R&E Community Yannis Mitsos 1 Panos Louridas 1 1 Greek Research and Technology Network October 2010

2 Presentation's structure Cloud services overview, Our currently offered services, Future initiatives/commitements,

3 Cloud services' categories The SPI model Figure: Cloud services' categories Software-as-a-service (SaaS) offerings are finished applications, Platform-as-a-service (PaaS) is a build-deploy-manage environment, Infrastructure-as-a-service (IaaS) is an on-demand virtual hosting environment. Source: Forrester

4 Cloud services' taxonomy Figure: A Taxonomy Of Cloud Computing Services Source: Forrester

5 Market analysis Figure: Cloud services' categories Source: Forrester

6 Rebuttal: Cloud's dark side Why companies remain reluctant adopting cloud computing? 1. Data privacy 2. Security 3. Licensing 4. Applications' redesign 5. Interoperability 6. Compliance 7. SLAs 8. Network monitoring

7 GRNET cloud service concept Enabling the Future Service-Oriented Internet A centralised services provisioning system Virtual working enviroment services Services targeted to the academic, scientific, research community while provide support to production / administration services as well

8 Current Services Do we offer any kind of Virtualised/Cloud services? GRNET Virtual Machine (ViMa) Service GRNET AAI Federation HellasGrid infrastructure Pithos online storage service. ViMa Scope.. Core services hosting Virtual Private Server (vps) hosting for our clients.

9 ViMa Service: after some rounds of redux Prerequisites: Actual cluster management A firm hypervisor Web frontend for OOB access / power control Open architecture :) Deployment: KVM Google's Ganeti project with GRNET NOC contributions Custom web frontend in Django (under development)

10 Ganeti: Shared-nothing Cluster No SPoF in the cluster Master node: cluster control, master IP address Master candidate: cluster configuration copy as master candidate Simple node: only as node controller If master fails: master failover to a master candidate. Our contribution.. Shared block-storage support (working migrations and failover), Changes in the KVM backend to support boot from HTTP and support of VNC. forwarding Google's presentation:

11 Coming Services Based on our experience with IaaS we will offer additional SaaS facilities: Scientific Software as a Service Labs / Science 2.0 Environments as a Service Administration Software as a Service Database as a Service Storage as a Service Grid as a Service (cf. StratusLab) Private cloud as a Service Hydrib cloud as a Service Disaster recovery as a S Data archiving / curation as a Service Backup as a Service

12 Science 2.0 Environments as a Service Web 2.0 applications, namely, logging, tagging and social networking, lead to the Open Science model. A new paradigm swift? Data-Intensive Science (aka repositories), Collaborative platforms, Virtual research environment: Desktop based workflow management system, Scientific tools sharing.

13 Project facts Kick-Off: September 1st, Budget: 10m (cost for a diversity of hardware is anticipated), Green disaster recovery site is envisaged, Open-source biased, Differentiate from currently available commercial services, following standard (?) commercial APIs, Quick time to deliver (as always),

14 Conclusions There are many supporting currents in our view of cloud computing: Economies of scale (favourable economic / market environment) Lack of sysadmin talent Quick to market (production) Long-term experience with providing quality services to the academia Excellent cooperation with the public sector / government, possible to exploit synergies (e.g., disaster recovery).
