Cloud computing is quickly becoming the standard way for technology companies to access IT infrastructure, software and hardware resources. The technology enables companies to be able to use applications and other resources managed by third party companies that are stored in high-end server computers and networks. Cloud computing helps businesses to be more efficient and save on software and hardware that are important for different operations.

2. Description of Cloud Computing
Cloud computing is quickly becoming the standard
way for technology companies to access IT
infrastructure, software and hardware resources.
The technology enables companies to be able to
use applications and other resources managed by
third party companies that are stored in high-end
server computers and networks. Cloud computing
helps businesses to be more efficient and save on
software and hardware that are important for
different operations.

3. Types of Cloud computing
Infrastructure as a Service (IaaS): IaaS is the
lowest level of cloud solution and refers to
cloud-based computing infrastructure as a fully-
outsourced service. An IaaS provider will deliver
pre-installed and configured hardware or
software through a virtualized interface. What
the customers accessing the cloud services do
with the service is up to them. Examples of IaaS
offerings are managed hosting and development
environments.

4. Benefits of Infrastructure as a Service (IaaS):
• Reduces total cost of ownership and capital
expenditures
• Users pay for the service that they want, on the go
• Access to enterprise-grade IT resources and
infrastructure
• Users can scale up and down based on their
requirements at any time

5. Types of Cloud computing
Platform as a Service (PaaS): This type of
cloud computing is similar to IaaS but is more
advanced. With PaaS, apart from simply
providing infrastructure, providers also offer a
computing platform and solution stack as a
service. The IT infrastructure may come with a
graphic user interface, run-time system
libraries, programming languages or an
operating system.

6. Benefits of Platform as a Service (PaaS):
• Community: Most of the time, many people are involved in building
cloud applications in PaaS environments. This creates a strong
supportive community that can help your development team along the
way.
• Lower cost: Companies face lower risk since they do not have to make
upfront investment in hardware and software.
• No more upgrades: Companies are not required to update or upgrade
the infrastructure software; instead, the PaaS provider handles all
upgrades, patches and routine software maintenance.
• Simplified deployment: The development team can concentrate on
developing the cloud application without having to worry about the
testing and deployment infrastructure.

7. Types of Cloud computing
Software as a Service (SaaS): When talking about cloud
services, most people think of Software as a Service (SaaS)
providers. SaaS providers provide fully functionally web-
based applications on demand to customers. The
applications are mainly targeted at business users and can
include web conferencing, ERP, CRM, email, time
management, and project tracking among others.

8. Benefits of Software as a Service (SaaS)
• Rapid Scalability
• Accessibility from any location with Internet
• Eliminates infrastructure concerns
• Custom levels of service offerings
• Bundled maintenance and Support

9. Types of Cloud computing
Recovery as a Service (RaaS): Recovery as a
Service (RaaS) solutions helps companies to
replace their backup, archiving, disaster
recovery and business continuity solutions in a
single, integrated platform. RaaS providers
protect and can help companies recover entire
data centers, servers (OS, applications,
configuration and data), and data (files and
databases). RaaS helps businesses to reduce
the impact of downtime when disasters
happen.

10. Benefits of Recovery as a Service (RaaS):
• Prevent temporary or permanent loss of
critical company data
• Prevents permanent loss of physical
infrastructure, including IT infrastructure
• Is a cost-effective way of recovering data
• Enables faster recovery while maintaining
accuracy
• Offer greater flexibility on the type of
backup required (either primary or
secondary backup)
