Cloud Computing

• Goal: – Understand basics of the Cloud technologies– Understand what potential it has from the business perspective– Understand types of Cloud Services– Understand the enablers, risks, benefits of the Cloud business


Content

• History of Cloud• Cloud infrastructure• Benefits/risks of Cloud• UDNC (User-Defined Network Cloud) high level overview• SaaS – software as a service• PaaS – platform as a service• IaaS – infrastructure as a service


History of Cloud

Sharing computing capabilities– One device – multiple terminals for users– Schools, offices, government buildings

VM (virtual machines)– One device – more operating systems performing different tasks used by multiple users

VPNs and Public internet– Providing products and services over the

internet to consumers– Providing products and services to business

over the VPN


History of Cloud

Cloud growth– big companies entering this business segment– IBM, Google, Microsoft, HP, Equinix, Amazon– taking customers from TELCOs, ISPs

Cloud “hyper-growth”– Since 2009, the Cloud business grew 400 % and is currently

worth 70 billion dollars annually• Used for business applications• Development of applications• Servers• Storage

Benefits of Cloud

Advantages• Cost:

– Fully utilized hardware– Lower power, real estate cost– Lower people cost– Lower up-front capital needs– Redundancy

• Access from any computer or device with an Internet connection– this device can be “dumb”

• Compatible with most computers and operating systems• Updates occur across the service• Rising competition in the market place• Pay per usage


Risks of Cloud

Disadvantages

• Possible downtime• Security Issues (internet vs VPN)• Compatibility• Terms of Service• Privacy Policies


UDNC (User-Defined Network Cloud) high level overview

• The User-Defined Network Cloud is a transformative initiative. Integrated through our Wide Area Network (WAN) and utilizing Network Function Virtualization (NFV) and Software Defined Networks (SDN), as well as modern architectural and operational approaches, we plan to simplify and scale our network by:

Separating hardware and software functionality;

Separating network control plane and forwarding planes; and

Improving management of functionality in the software layer.

PaaS – platform as a service

• Platform as a Service (PaaS) is a way to rent hardware, operating systems, storage and network capacity over the Internet.

• Provided environment can be used to develop applications• The service delivery model allows the customer to rent virtualized servers

and associated services for running existing applications or developing and testing new ones.

• Facebook (from Developer Community standpoint)• BMW (virtual wind tunnel facility)


IaaS – infrastructure as a service

• Infrastructure as a Service (IaaS) is a provision model in which an organization outsources the equipment used to support operations, including storage, hardware, servers and networking components.

• User can move their existing datacenter into cloud provider shared datacenter

• User can rent hardware to establish their own platform, development environment

• Any company that wants to move its existing IT infrastructure into providers Cloud environment


AT&T business model for Cloud

• What is AT&T’s business?

• Is AT&T a true competitor for the big Cloud players?

• What needs to be done to get a bigger share of the Cloud business?
