3. Introduction: There was a time when... At the high street bank: the only place you could withdraw your money from was the branch with which you held your account. If you weren’t near it… :/ The only way you could draw money from a hole in the wall was to use your bank’s ATM network. It was private. Disconnected from all other bank networks. So if you weren’t near an ATM belonging to the bank you banked with… :/ You could only use the cards you had in the country you lived in. If you had to travel anywhere else… :/ There were no guarantees for what happened if someone impersonated you, if your cards were stolen, or, for that matter, your bank had a problem.  No guarantee schemes.
4. Introduction: But today... Today we can choose who to bank with, draw money from any branch, any ATM, anywhere, anytime. Securely, efficiently, conveniently. Underpinned by the trust that comes from feeling secure, having guarantees. We can store the Kit Jambon in DropBox Thanks Cloud Computing

8. I. What is Cloud Computing? Cloud computing means storing and accessing data and programs over the Internet instead of your computer's hard drive. For it to be considered "cloud computing," you need to access your data or your programs over the Internet Access to your data anywhere, anytime Some numbers: The market is on its way to generating $100 billion a year 80% of the large companies in North America are either looking at using cloud services or already use it. Examples: Google Drive, Dropbox, e-mail, Facebook...

Available an can be accessed as required without the need to upgrade. Cloud services require only the internet and monthly subscription Speed and Convenience Work in the cloud is accessing applications via a web browser Easy and fast to set up. No need of employee training Data storage Great level of security File backups Ability to scale your IT services

20. V. Legislation issue Do you know something about legislationapplied to your data stored in a cloud?
21. V. Legislation issue Considerthat: In the presentationday, the videoswereincluded in the slides. There was no need to copy the videos links into a web browser. Video Link: http://www.youtube.com/watch?v=nKHkT9RWSGI
22. V. Legislation issue What if the hostermakes an improper use of your data? Triangulardiplomacy: States Companies Inter-states relations
23. V. Legislation issue Your data isunder the regulation of the hoster location: Meaning: Legalframeworkthatyou’rehosterissubject to matters « It islawful in the US to conductpolitical surveillance on foreigners’ data accessible in US Clouds. » Quotefrom the Policy Department of the EuropeanParliament
24. Debate time! Does the previousstatementmakesyoureact in anyway? Reminder: « It islawful in the US to conductpolitical surveillance on foreigners’ data accessible in US Clouds. »
25. VI. Embrace the cloud computing revolution – with caution Move everything to the cloud, and use it in an on-demand way?  Not yet Example: Google Docs do many things well enough for non-complextasks. Outages Online databases are vulnerable to hacking One reason the cloud has become so useful is the same reason we should have a "local storage" backup as well: Backup Portable hard disk: 2 terabytes (2 million megabytes) of storage for under $150 Neverthless: disk failure and physical loss
26. VII. A quick view of Cloud providers Apple Icloud: Store your music, photos and documents Works on any Apple Devices or on PC with iTunes Microsoft Skydrive: Virtual hard drive Works on PC, Mac and Windows Phone / RT
27. VII. A quick view of Cloud providers Oracle on demand, Akamai, abiquo, Cloud9 analytics…
28. VIII. Cloud computing: how to get your business ready The cloud strategy: big and small companies there is an extraordinary rush underway to deploy and go live with their cloud offerings Twelve years ago, it took a company six to eight weeks to commission a server Putting your IT into the cloud allows you to have a new server in 30 seconds, and to innovate and grow faster Global economic crisis: more companies use the cloud The price of cheap: standardization and almost no customization
29. VIII. Cloud computing: how to get your business ready Mobile demands The cloud is also the perfect answer to the surge of corporate mobility Using cloud services saves companies from building the expensive infrastructure to support mobile solutions Agile growth Most companies pay good IT money for little return. Their servers usually run at 15% to 25% of capacity at most  extra storage or computing power can be switched on in an instant, and it is this agility and scalability that persuades most companies to venture into the cloud
30. VIII. Cloud computing: how to get your business ready The Cloud check list Check out the reputation of the service provider: How long have they been offering cloud services Security is key. Really understand how secure your data have to be, and ask the vendor how they would solve your security problems Investigate how the cloud provider makes back-up copies of your data, how you can move the data to another provider, and what happens if the provider goes out of business ...
31. VIII. Cloud computing: how to get your business ready Work hard to get a good service level agreement with clear financial penalties to ensure a good service Be wary of industry certifications, because they capture just a moment in time. Do your own research on how the vendor is performing Finally, try the service. The beauty of cloud computing is that it's easy to switch on and off. Obviously don't start your cloud adventure with confidential data or mission-critical systems, but if the service works for you, you can expand.
32. VIII. Cloud computing: how to get your business ready Culture shift The risk is in allowing that small private cloud to grow faster than your organization, people, and processes and business model changes can handle it Moving into the cloud is a cultural shift as well as a technology shift Example: To "onboard" a new employee - putting them on the HR system, sorting their payroll, giving them access to the company's customer relationship management software, providing mobile access to the corporate IT etc - may involve half a dozen cloud services.
33. VIII. Cloud computing: how to get your business ready Companies moving into the cloud will soon require a "cloud aggregation service" that integrates the patchwork of cloud services with a company's core IT systems?
34. IX. Companies that provide enterprise cloud computing platforms should… Transparency: explain their information handling practices and disclose the performance and reliability of their services on their public Web sites. Use Limitation: claim no ownership rights in customer data and should use customer data only as their customers instruct them, or to fulfil their contractual or legal obligations. Disclosure: disclose customer data only if required to do so by the customer or by law, and should provide affected customers prior notice of any legally compelled disclosure to the extent permissible by law.
35. IX. Companies that provide enterprise cloud computing platforms should… Security Management System: maintain a robust security management system that is based on an internationally accepted security framework (such as ISO 27002) to protect customer data. Customer Security Features: provide their customers with a selection of security features to implement in their usage of the cloud computing services. Breach Notification: notify customers of known security breaches that affect the confidentiality or integrity of their customer data promptly.
36. IX. Companies that provide enterprise cloud computing platforms should… Audit: use third-party auditors to ensure compliance with their security management system and with these principles. Data Portability: make available to customers their respective customer data in an industry-standard, downloadable format. Accountability: work with their customers to designate appropriate roles for privacy and security accountability. Make sure you verify al these items before signing a contract with a company that provides cloud computing.
