NPTEL-CC-Week1

Intro ->CC Architecture-> Service Management-> Resource Management-> Data Mangement-> Security-> Case study on open source and Commercial Clouds, cloud Simulator -> Research trend in CC, Fog Computing

Pre-overview: Distributed, Grid, Cluster, Utility & CC

CC -> Defintion, Characteristics ( on demand, Broad network, Resource pool,Measured servic, Rapid Elasticity), Common Charactersitcs( Massice Scale, Resilient, Homegeneity, Geographic distribution, Virtualization, Service Orientation, Low cost s/w, Advanced Security)

CC service Models -> SaaS, IaaS, PaaS

Tpes of Cloud (Deployment models) - > private, community, public, Hybrid

Cloud & Virutatilzation -> Cloud Sourcing - > Storage (Eg: Amazon-EC2 & S3)->Adv&disadv->3 main Reasons still to go r cost, capacity illusion, low utlization in private

IaaS Economics -> Purchase cost, cost/hr for 3yrs can get the cost ratio for cloud/inhouse= Efficiency, cost/hour,power/coiling, mgmt cost give total cost/effective hr as Costratio inhouse/cloud

Benefits of 1. Public., 2. for Small&Medicum businesses, 3. Private

Economics of Paas vs IaaS -> IaaS for servers, PaaS for web appication

PaaS benefits, SaaS benefits , Benefits as perceived by IT, Factors for investment(cost, fexibility and scalability main reasons)

Purpose of CC in organizations:

NPTEL- CC - Week 0

IP datagram -> Header Fields -> Time to Live(TTL)-> Is used to prvent packet looping

Process sate transitions for preemptive scheduling-> a running process can move to ready state, a ready process can move to ready

state, a blocked process can move to ready sate.

System calls in sending SYN packets->connect

Hosts per subnet?

System with 3 processes that has 4 instances of same resource type. Each process request max k intances..deadlock question
