What is cloud computing?
Why cloud computing?
HealthCare in the cloud Computing Evolution : Computing Evolution Now 70’s 80’s 40’s Mobility explosion
High level of interconnection between users
Web platform growing
Pressure over companies data centre. What is cloud computing : What is cloud computing “Cloud” is actually a metaphor for the Internet.
User do not have or need knowledge, control, ownership in the computer infrastructure.
Users simply rent or access the software, paying only what they use What is cloud computing : What is cloud computing Cloud computing is using the Internet to access someone else’s software running on someone else’s hardware in someone else’s data centre while paying only for what you use. Cloud anatomy : Cloud anatomy SaaS = Software as a Service
(eg: Gmail, Google Calendar,...)
PaaS = Platform as a Service
(eg: Google Apps)
IaaS = Infrastructure as a Service
(eg: Amazon EC2) Cloud architecture : Cloud architecture Private Cloud Cloud architecture : Cloud architecture Public Cloud Cloud architecture : Cloud architecture Hybrid Cloud Why cloud computing : Why cloud computing Data centres are notoriously underutilised, often idle 85% of the time
Insufficient capacity planning and sizing
Improper understanding of scalability requirements etc
including thought leaders from Gartner, Forrester, and IDC—agree that this new model offers significant advantages for fast-paced startups, SMBs and enterprises alike.
Cost effective solutions to key business demands
Move workloads to improve efficiency Why cloud computing - Traditional IT : Why cloud computing - Traditional IT Why cloud computing - Cloud : Why cloud computing - Cloud Why cloud computing : Why cloud computing Instant Elasticity
Scale up / down
Reduce IT Cost
Pay only what you use
Green / CO2 footprint reduced
The servers unused are switched off automatically.
No need any more powerful computer to run powerful software Healthcare in the cloud : Healthcare in the cloud IT requirements
functional and non-functional are more complex.
We care about where the data are stored and who take care of them.
The public cloud cannot really meets these needs.
The cloud vendor can keep our data anywhere.
The private cloud could pretend to be more secure but the maintenance's cost of the infrastructure is still present. Healthcare in the cloud : Healthcare in the cloud The hybrid cloud could be the solution.
The private side could only be used to process, store sensitive data.
The public side could be used to compute non sensitive data.
BUT difficult to implement.
Strong policies rules must be implemented to target the both cloud. Healthcare in the cloud : Healthcare in the cloud Understanding that cloud infrastructure brings many advantages for the hospitals nevertheless the public cloud architecture, most economic with endless resources cannot really be enjoyed by hospitals.
The best solution could be to introduce a new cloud architecture which could take only advantages of the 3 existing architecture.
The government could create their own private cloud and propose IaaS/ PaaS / SaaS to the UK hospitals. Healthcare in the cloud : Healthcare in the cloud Protected Cloud Who already used the cloud : Who already used the cloud Peter Harkins at The Washington Post: 200 EC2 instances (1,407 server hours), convert 17,481 pages of Hillary Clinton’s travel documents within 9 hours
The New York Times used 100 Amazon EC2 instances + Hadoop application to recognise 4TB of raw TIFF image into 1.1 million PDFs in 24 hours ($240)
The U.S. Defense Department is offering now cloud computing services. Thank you : Thank you
