The document discusses cloud computing in the public sector and provides examples of government cloud initiatives. Some key points: - Governments are deploying clouds to fundamentally change business models, increase transparency, and reduce costs. - Examples of government cloud programs include the UK's G-Cloud, Japan's Kasumigaseki Cloud, and the US Federal Cloud Computing Strategy. - Use cases show how the Tunisian government and STEG company could realize efficiencies through cloud adoption, including cost savings and improved productivity. - The document proposes a Tunisia Cloud Store and six-step migration strategy to help public sector organizations transition to the cloud.

Tunisia

3. “In the years ahead, more and more of the information-processing tasks that we rely on, at home and at work, will be handled by big data centers located out on the Internet. The nature and economics of computing will change as dramatically as the nature and economics of mechanical power changed with the rise of electric utilities in the early years of the last century. The consequences for society—for the way we live, work, learn, communicate, entertain ourselves, and even think— promise to be equally profound. If the electric dynamo was the machine that fashioned twentieth century society—that made us who we are—the information dynamo is the machine that will fashion the new society of the twenty-first century.”

WHAT IS CLOUD COMPUTING?
Cloud computingis the delivery ofcomputingas aservicerather than aproduct, whereby shared resources, software, and information are provided to computers and other devices as autility(like theelectricity grid) over anetwork(typically theInternet).
Clouds can be classified as public, private orhybrid.

The “KasumigasekiCloud”: JaponGovernment Cloud
In Japan, the national government is undertaking a major cloud computing initiative, dubbed the “KasumigasekiCloud”. The initiative seeks to develop a private cloud environment that would eventually host all of the Japanese government’s computing(Ng, 2009). According to Japan’s Ministry of Internal Affairs and Communications (MIC) , the KasumigasekiCloud will allow for greater information and resource sharing and promote more standardization and consolidation in the government’s IT resources.
This represents a governmental effort aimed at using IT investments (valued at just under 100 trillion yen) to help spur economic recovery by creating several hundred thousand newIT jobs in the next few years and doubling the size of Japan’s IT market by 2020

UK Government Cloud: G-Cloud
G-Cloudis a UK government program designed to change the way the public sector procures and operates ICT by the adoption of cloud computing services and resources.
By using the cloud, and also opening the market to smaller suppliers and newer technologies, the G- Cloud programmehas the following goals:
Achieve large, cross-government economies of scale
Deliver ICT systems that are flexible and responsive to demand
Deliver faster business benefits and reduce cost
Meet environmental and sustainability targets
Allow government to procure in a way that encourages a dynamic and responsive supplier marketplace.

UK Government Cloud: CloudStore
The CloudStoreis the easy way for the whole of the UK public sector to buy cloud computing commodity and support services. It is an online cataloguecontaining details of each of the G-Cloud suppliers and their services.
All types of cloud services are available in the CloudStore, including Public, Private and Hybrid, with offerings under four Lots:Infrastructure as a Service(IaaS);Platform as a Service(PaaS);Software as a Service(SaaS);andSpecialist Cloud Services(SCS) –so whatever your needs, we’re likely to have something to offer. All the services listed on the store are part of the G-Cloud frameworks so are immediately available for the public sector to procure and use by following the buying guidance under the Customer Zone in the section Explore the store below.

USA FederalCloud Computing
Cloud computing offers the government an opportunity to be more efficient, agile, and innovativethrough more effective use of IT investments, and by applying innovations developed in the private sector, If an agency wants to launch a new innovative program, it can quickly do so by leveraging cloud infrastructure without having to acquire significant hardware, lowering both time and cost barriers to deployment.
This Federal Cloud Computing Strategy is designed to:
Articulate the benefits, considerations, and trade-offs of cloud computing
Provide a decision framework and case examples to support agencies in migrating towards cloud computing
Highlight cloud computing implementation resources
Identify Federal Government activities and roles and responsibilities for catalyzing cloud adoption
