o Hybrid Cloud is comprised of both public cloud and private cloud. In a
hybrid cloud, data and information can be transferred for better flexibility.
Here we can say that the public cloud is used for where less security
persists like webmail, whereas private cloud used when security is at peak
and for critical business operations. A hybrid cloud is used for better
control and cost-effectiveness that it provides.

How does IaaS Works?

IaaS points to an infrastructure either physical or virtual that is provided by the
cloud provider. IaaS has lots of resources such as network, server, storage,
virtualization, so it depends upon the customer to choose its resources wisely and
as per need. Apart from the management of the infrastructures, it provides billing

management too, where the user is billed as per the services rendered.

Benefits of IaaS
IaaS offers lots of benefits to its customers ensuring affordability and business
growth. Given below are few benefits:
o IaaS provides a “pay per use” scheme, which says the services provided
can be used as per needed, and users need to pay only for the services
utilized.
o The services provided by IaaS are quite scalable as they make sure that
the resources are available to the users at the desired time and demand
and also ensure that there is no wastage of capacity if left out.
o It saves a lot of time and cost as the cloud service provider is responsible
for setting and maintaining the physical hardware.
o The service provided is unaffected and remains constant, even though any
hardware failure occurs.

quickly as per the needs of customers.
o IaaS mostly focuses on business growth as there any hardly any time is
spent on technological and business decisions and how to maintain the
infrastructure. IaaS takes care of all of these.
o IaaS cloud computing platform provides secure data centres with
24/7/365 availability.
