. Nowadays, privately held as well as public Cloud computing services
hold the promise to deliver a host of benefits to both public sector organizations and
enterprises, including reduced Capital Expenses, improved performance and
scalability, enhanced reliability, as well as an overall reduced Total Cost of
Ownership for their ICT infrastructures and services. At the same time, the ability to
combine public cloud services could open new horizons for the development of a next
generation of innovative cloud services that fully leverage existing services and APIs.
These benefits are particularly important for public bodies, especially for
governmental agencies, municipalities and regions, all over the EU; the adoption of
public cloud services as part of their numerous e-government transactions is expected
to have a significant economic and social impact

.
Despite these potential benefits, their penetration within public sector
organizations is still low

. Furthermore, cloud use in the public sector is usually
confined to the use of simple on-line back-office services (e.g., document
management, document sharing, mobile access to document), with only few instances
of use of e-government services by European citizens. Furthermore, security and
privacy management mechanisms (along with related policies) are not yet fully
integrated into public cloud services. This is a significant lost opportunity in an era
where governments are under extreme pressure to reduce operational budgets, while
at the same time citizens seek opportunities for increased satisfaction at less time and
lower cost.
However the current state of the art of cloud computing is slowing finding its way
to public sector. Governments are replacing their legacy IT systems with cloud
computing technologies and implementing new cloud-based tools for collaboration
and information sharing across agencies and units. Cloud Computing provides a great
opportunity for enabling reliable e-Governance quickly and at lower costs, while if
the needs have to be covered in-house they will have to cover peak demands (at
specific points of time) paying for over provisioning and leaving part of the
infrastructure unused for significant amounts of time. Cloud computing features like
application virtualisation, end-to-end service management, instant deployment and
ease of maintenance are catalysts, that jumpstart application deployment on the
Cloud. The biggest benefit of the Cloud is that it helps consolidate all data centres and
optimize resource utilisation, reducing support and maintenance costs by more than
half, without compromising on performance, availability and reliability of
applications

Centralising data storage and processing offers economies of scale that even the
largest organisations cannot achieve by themselves. Cloud computing therefore
represents considerable savings in IT budgets, and the end of headaches linked to
older computing methods. Private sector businesses using cloud computing report 10-
20% lower IT costs, while cloud computing can also help the public sector improve
efficiencies and lower costs, according to European Commission

According to European Union Agency for Network and Information Security
(ENISA), public bodies can be a key player in Cloud computing area as it offers
scalability, elasticity, high performance, resilience and security, together with cost
efficiency while at the same time it can enable and simplify citizen interaction with
government by reducing information processing time, lowering the cost of
government services and enhancing citizen data security. Governmental Clouds offer
