What Is Cloud Computing

● Cloud = Internet. The name comes from the use of a cloud-shaped symbol as an abstraction for the complex infrastructure it contains in system diagrams. Cloud computing entrusts remote services with a user's data, software and computation.

● Cloud is the use of computing resources (hardware and software) that are delivered as a service over a network (typically the Internet)

● Cloud Computing" is the current trend and future computing model based on Internet. It is a new way of delivering IT services to customers called IaaS, PaaS, and SaaS where the hardware and software are no longer sold but rented just like utilities such as electricity, etc. All the users need is just a computer with browser, just like accessing Facebook, and all the rest of the hardware such as the server will be on the "Cloud" or somewhere out there at the vendor’s premises

3 Major Services Available on the Cloud

● IAAS (Infrastructure As A Service): Businesses rent the hardware: processor and data storage.

● PAAS (Platform As A Service): Businesses rent the hardware, operating system, and development tool to

run their own developed applications.

● SAAS (Software As A Service): Businesses rent everything namely hardware, operating system, and

application software to run it just using a simple notebook with an internet browser.

● Other services terms such as : MaaS, CaaS, Xaas

Cloud Examples

● SaaS : Public Email (Gmail, YahooMail, Hotmail, etc), social network (Facebook, Twitter, etc) and also Software through cloud (Office365, Adobe Creative Cloud, Google Docs/Drive, etc)

● PaaS : Amazon Web Service, Windows Azure● IaaS : Amazon EC2, BizNet Cloud,

TelkomCloud

What do you Use?● Email on the go

Google, Yahoo

● Online Storage Services Humyo, Microsoft SkyDrive, Amazon S3,

Ubuntu One,

● Working in Virtual Office (Collaboration of Software & Office Suite)

Google Docs, Office Live, Adobe Cloud

● Social Networking Google+, Facebook, etc

Typical Users of Cloud

● Startups (cheap infrastructure, low investment)● Entertainment (highly scalable, temporary

systems; think movie promotional campaigns)● Small businesses (similar motives to startups)● Enterprises (quick and cheap experimentation)● Consumers, Society (as users who demand

high services, cheap payment, almost everywhere access and ease of use of the products and services)

Cloud Deployment

● Public Cloud Public cloud applications, storage, and other resources are

made available to the general public by a service provider. These services are free or offered on a pay-per-use model. Generally, public cloud service providers like Amazon AWS, Microsoft and Google own and operate the infrastructure and offer access only via Internet (direct connectivity is not offered

● Private Cloud Private cloud is cloud infrastructure operated solely for a

single organization, whether managed internally or by a third-party and hosted internally or externally.

Cloud Deployment

● Hybrid Cloud Hybrid cloud is a composition of two or more clouds (private,

community or public) that remain unique entities but are bound together, offering the benefits of multiple deployment models.

● Community Cloud Community cloud shares infrastructure between several

organizations from a specific community with common concerns (security, compliance, jurisdiction, etc.), whether managed internally or by a third-party and hosted internally or externally.

Cloud Impact● Advantages :

Cost Efficient. Cheaper. Easy to Access. Easy to Manage. Environmental Aspect. ● Disadvantages :

Security Issues.

Infrastructure Issues.

● Key Points :

Choosing Reliable Third Party Cloud Providers

Business with cloud services become more efficient and thus profitable. Consumers will have fast, cheap, competitive

services of a Cloud World ( Service Centric World)

Cloud World ( a Service Centric World)

● Cloud created 100,000 new IT jobs in 3 months http://www.nwcet.org/new-job-opportunities-flow-from-advanced-technology/

● Cloud Computing is Converged Infrastructure and Shared Services →

● Cloud computing relies on sharing of resources to achieve coherence and economies of scale similar to a utility (like the electricity grid) over a network

● Cloud Computing as ICT technologies that represents an infrastructure revolution, moving infrastructure use from a capital expense to an operational expense and cutting the overall cost by at least 90 percent. http://pcworld.about.net/od/softwareservices/Who-s-Getting-ROI-From-Cloud-C.htm

● Cloud Computing is part of Internet Infrastructure that playing role of globalization enabler and the ICT Paradigm that provides the opportunity of spaces fot the global development and ”golden era”

Once upon a time..
