Agenda

• Introduction• What is Cloud Computing ?• Economics of Cloud Computing• Major Issues in Cloud Computing• Security Issues• Next Generation Cloud Computing

What Is Cloud ?????• Old ideas:

– Grids, vector supercomputers– Software as a Service (SaaS)

• Def: delivering applications over the Internet

• Recently: “[Hardware, Infrastructure, Platform] as a service”– Poorly defined so we avoid all “X as a service”

• Utility Computing: pay-as-you-go computing– Illusion of infinite resources– No up-front cost– Fine-grained billing (e.g. hourly)

What Is Cloud ?????

Types Of Cloud

• Private Clouds Typically owned by the respective enterprise • Public Clouds Outsource services to others• Hybrid Clouds Outsource part of services to others

Types Of Cloud

Unused resources

Economics of Cloud Users• Risk of over-provisioning: underutilization

• Huge sunk cost in infrastructure

Static data center

Economics of Cloud Users

Unused resources

• Pay by use instead of provisioning for peak

Very hard to provision for spiky workloads

Risk of underutilization if

peak predictions are too optimistic – Wasted CapEx

Benefits Of Using Cloud

• Cost reduction • Pay per use• Improved time to market • Return of Investment (RoI)• Turning CAPEX into OPEX

Major Issues in Cloud Computing

• Manageability• Privacy & Security• Data Management• Federation• Interoperability• Virtualization, Elasticity and Adaptability• APIs, Programming Models & Resource

Control

Interoperability Issues

Solutions• Open Cloud Platform• Regulations• Global protocols• Interoperability

Next Generation Cloud Computing

Intel Cloud 2015 Vision

Features of Intel Cloud Vision

• Federated: easy movement between different cloud infrastructures

• Automated: resource scaling management is automatic

• Client-aware: dynamically sense and take advantage of client device platform

Features of Intel Cloud Vision
