WHAT IS CLOUD COMPUTING ?
 Cloud computing is a type of computing that relies on sharing computing
resources rather than having local servers or personal Devices to handle
application.
 In cloud computing, the word cloud is used as a metaphor for "the Internet,"
so the phrase cloud computing means "a type of Internet-based computing,"
where different services -- such as servers, storage and applications -- are
delivered to an organization's computers and devices through the Internet
 The cloud is itself a virtualisation of resources such as networks,
servers, applications, data storage and services.
 It can provide the user with many applications and services on
demand via the web

• It is the result of evolution
and adoption of existing
technologies and paradigms.
• Goals of cloud computing
• Virtualization
• Autonomic computing

Failure Cases
• Simulation parameters
• Average bounded slowdown and average per-processor slowdown
• Average waiting time & average weighted waiting time
• Network Error
• Computational Error
• Power Failure
• Queue Overflow

8.
Feedback and Update
• When we get feedback from server that a particular activity
is completed then we can schedule its dependent activity
from waiting queue to its destination server.
• After that each resource table and universal resource table
gets updated.

Flow of Algorithm

10.
• Cloud computing presents enterprises
with significant cost and agility benefits
that IT will struggle to leverage due to
security and control constraints
• If IT doesn’t provide business units with
easy access to inexpensive cloud
services, they will engage with external
providers themselves, bypassing IT
policy and control

11.
Conclusion
• Cloud computing is a really cheap way for companies to
have all the resources they need in once place.
• It’s a much better way to spread your resources, and it
becomes easier to access things from longer distances.
But…
• Is cloud computing really all that safe? For instance,
while cloud computing has backups, if something was to
go wrong… do you have your own personal backup?
• Is cloud computing as private as you think it is? Is your
data secure or can anyone access it?
