Cloud Computing - TRAI Report

Cloud Computing four attributes:

• Data Intensive - focus is on data rather computation, (I/O) is more important resource metric than CPU utilization
• Resource Pooling - instance of program to serve different consumers (multi-tenancy)
• Scalability & Rapid Elasticity - Scalability - automated ability of cloud to scale IT resource, Elasticity is scalability supported with optimized utilization of resources as well as cost optimization
• On demand access - freedom to selfprovision these resources, pay-as-you-go approach with no upfront commitments

Top Verticals such as Retail, Railways, Manufacturing, Banking, Education and Healthcare using cloud like

• Public cloud
• Private cloud
• Community cloud
• Hybrid cloud

for

• Content, Communication and Collaboration (CCC)
• Customer Relationship Management (CRM)
• Enterprise Resource Planning (ERP)
• Supply Chain Management (SCM)
• Other Integrations

through Service Models:

• Software as a Service (SaaS)
• Platform as a Service (PaaS)
• Infrastructure as a Service (IaaS)

also Other:

• Data as a Service (DaaS)
• Identity and Policy Management as a Service (IPMaaS)
• Network as a Service (NaaS)
• Video as a Service (VaaS) 
• Hardware as a service (HaaS)

Supply-Side Economies of Scale:

• Cost of power
• Infrastructure labour costs
• Security and reliability cost
• Cost of architecture - Operators

Market Predictions for Cloud Computing

• Smart city technologies will drive up demand for Internet of Things (IoT)
• Public cloud
• Software-as-a-Service (SaaS) market
• Social, Mobility, Analytics and Cloud

Interoperability Requirements: Data Portability, System/Application Portability

Ensuring Quality of the Cloud : High availability, Performance, Security, Resilience, Reliability, Self-service Portals, Response time & Customer support, Metering/Billing Accuracy, Support in Compliance of Regulations

Compliances: Loss of Service, Audit, Service Conformity

Key Parameters of QoS in Cloud: Availability, Performance, Response time, Scalability through dynamic provisioning of Resource, Metering and Billing/Charging performance.

Major Threats:  (i) Abuse and Nefarious Use of CloudComputing, (ii) Insecure Application Programming Interfaces, (iii) Malicious Insiders, (iv) Shared Technology Vulnerabilities, (v) Data Loss/Leakage, (vi) Account, Service & Traffic Hijacking and (vii)Unknown Risk Profile.
