Public cloud computing provides organizations flexibility, cost reduction, and regular automatic upgrades. Some key benefits of adopting public cloud include flexibility for employees to access data remotely, reduced IT costs as organizations pay only for the resources they use, and automatic software/hardware upgrades managed by cloud providers. However, security is a primary concern for organizations considering public cloud. Service level agreements and ensuring robust security controls, privacy policies, and technical measures can help address these concerns. Migrating workloads to public cloud requires validating applications' technical portability and compliance.

1. What Are The Advantages Of
Adopting Public Cloud?
Quick Summary: Public cloud computing brought a fundamental change from
the conventional norms of an organizational data center to a parameterized
open environment to use by adversaries.
Public cloud can be stated as a stand-alone, or proprietary, an off-premise model
that is run by third-party companies such as Google, Amazon, Microsoft, Salesforce,
and others. Public Cloud Computing is generally a mix of applications from
anonymous consumers on shared infrastructure.
Public Cloud as a Strategic Business
Decision
Public cloud uses Internet-based technologies to deliver dynamically provisioned,
standardized business processes, applications and infrastructure services, and
resources.
Public cloud is typically managed by an off-site, third-party provider to any business.
Some of the renowned public cloud examples are Google Apps, iPhone apps, and
Amazon’s Elastic Compute Cloud (EC2). IBM has united with Amazon to enable
software developers that quickly build pre-production applications based on IBM
software within the Amazon EC2 environment.

With time and experience, enterprises and cloud service providers have become
accustomed to the architectural model and have gained substantial confidence in
delivering the security and access-control technologies available. As a result, we now

2. see public cloud service providers offering services as a third party in a much
seamless and effective way.
What people understand by ‘Public’ is freely accessible, which is not completely
correct. You can say the public cloud has some features free and others less
expensive to use than the other cloud platforms.
Moreover, the public does not mean the data is open for all to view. The public cloud
offers elasticity and cost-effectiveness to deploy solutions, but for entire data
transparency or accessibility, it all depends on the user. The third-party service
provider offers an access control mechanism to those who want to keep their data
hidden.
The reason why SMEs are inclined towards the public cloud is it gives you the
flexibility to pay as you go. This model is the most attractive as it is cost-effective,
where all customers share the same infrastructure but with limited configuration, yet
with security protection and availability variance.
Cloud Computing supports interactive and user-friendly web applications and
dynamic software development. Be it private or public, the cloud has an important
role in innovatively scaling business. The public cloud has the new and improved
capabilities of cloud computing that a conventional IT solution cannot proffer. Along
with minimum infrastructure and resources, there are various other benefits of
integrating the Public cloud within your organization.
Benefits of Adopting Public Cloud In
Your Business
Flexibility
In order to enhance flexibility within the business processes, many companies have
chosen the adoption of cloud computing. Not just in-house, the cloud offers an
employee to freely travel or work remotely while accessing the data via the Internet
through any device. This helps the organization to better handle demands, allow

3. sharing of the documents and files, keeping every employee updated on the
processes of activity, & many more. The identical documents issue can also be
resolved with the cloud as it allows employees to access and update the data at
regular intervals as per their requirement.
Cost-Reduction
Another advantage of cloud computing is a reduction in the exorbitant prices paid by
the organization for resources and infrastructure. With the help of in-house
provisions of the services, the cloud makes the business processes easy and
cost-effective. Cloud asks to pay money for the services that you use when accessing
cloud services instead of whole. The cost-effective feature of the cloud encouraged
45.5% of organizations to adopt the services saving them from huge monthly or
yearly subscription plans. The cloud resources like SaaS, PaaS, and IaaS can be
installed and deployed quickly.
Cloud Service providers are the key to managing, patching, and upgrading cloud as
well as maintaining the services. By engaging service providers, you can easily reduce
the cost and burden of hiring IT staff to manage them.
Regular and Automatic Upgrades
Maintaining and upgrading the current software and hardware was a back-breaking
and arduous job until the cloud emerged. The huge cost was the reason behind most
companies’ negligence in upgrading their hardware and software, which lead to a
negative impact.
After the rise and progression of cloud computing, companies were free from the
exorbitant prices, also able to build better relationships while constantly remaining
in technological advances, enhance profit, provide standardized services to the
customer at a very low price.

Further, reduced cost and improved efficiency encouraged companies to engage in
automatic processes by buying Supply Chain Management and Customer

4. Relationship Management applications. Today, most of the companies are leveraging
these automated applications to ease and pace up the work concerning the demand.
Agile Management
In order to match the competitive world, businesses are forced to speed up their
business processes and development. Highlighting the ways to make your
organization different from others will help the organization to respond to the
customer’s fast-changing needs. And cloud computing has also excelled at this level
by providing the organizations with the ability to reach out to customer’s needs in a
more effective manner. Thanks to the Internet, the cloud is around us 24 hours, 365
days. The three types where cloud computing can increase agility are –
● System Infrastructure – for machines and spare part maintenances
● Backup Policy – for backup management
● Single Application – for software management (upgrades or application
support)
Compared with cloud servers, it just takes minutes for cloud computing to procure
and provision.
Scalability
One of the major benefits of adopting Cloud computing over IT solutions or cloud
servers is scalability, which allows users to adjust the resources based on changes in
business needs. Like the aforementioned, the cloud is interactive, businesses can
expand the computing infrastructure, unlike the ​IT solutions that are inconvenient to
upgrade with changing needs.
Through the scalability feature of the cloud, a business can focus on solving key
problems in less time and increase customer satisfaction.
Cloud computing suggests or makes resources quickly available, which reduces the
capacity planning needs. Moreover, cloud computing allows its users to analyze
immense data in just a few minutes, which is an added advantage for even small

5. organizations, allowing them to analyze the market and predict customers, their
behavior, and buying habits.
Addressing the Security Concern of
Public Cloud Computing
Cloud Computing emergence promises far-reaching effects on the systems and
networks of the organization. The features that make cloud computing so exciting
and fascinating can become quickly vulnerable to threats as they follow the
conventional security models and controls. Public cloud computing needs to consider
involving robust security and privacy systems.
Organizations, before engaging in a cloud computing solution, must analyze whether
the service provider can meet the security, privacy, and other requirements or not.
Security and privacy are the primary concern for any government or private
organization. Since different organizations have different levels of data privacy and
security objectives, thus the perspective of each organization must be clarified
before instigating cloud solutions.
Service Level Agreements
The specifications of public cloud service and its arrangements are defined within the
SLA. It also notifies the period of the service, conditions of termination, and
disposition of data upon termination. The multi-documented SLA typically consists of
an understanding of the policy, acceptance of use, terms of use, compensation of the
failure of expected and specified level of services to the cloud customer, which is
agreed by the organization and the service provider respectively.
You can either go for the non-negotiable agreement, where the provider can make
modifications to the terms of services without directly notifying the consumer. Or
rest on negotiated service agreements, which is more like a traditional contract that
addresses the organization’s concerns about security, privacy policy, procedures, and
technical controls.

6. Upsides of Security and Privacy
The Cloud Computing paradigm offers opportunities for innovation in provisioning
security and privacy services for improving the overall security of the organization.
However, those that will benefit are likely to be small organizations due to limited
data for concern.
Today, privacy has broader implications concerning organizational, operational, and
technical. Other aspects of privacy can be confidentiality, integrity, and availability
objectives of security.
The potential areas where organizations can derive security and privacy benefits
from transitioning into public cloud computing are –
Staff Specialization – Cloud Service providers can train staff of the large organization
to specialize in security, privacy, and other respective areas of concern. Through such
an opportunity, staff members can take remedial actions, make improvements to
security and privacy more readily.
Platform Strength – ​The structure is typically uniform of any cloud computing
platforms, which allows greater uniformity. The homogeneity facilitates better
automation of security management activities such as configuration controls,
vulnerability testing, security audits, and security patching of components. Cloud
Computing environments meet standards for operational compliance and
certifications for imparting a level of assurance and acceptance criteria.
Resource Availability – The scalability of the public cloud offers greater availability,
redundancy, and disaster recovery capabilities for better resilience. Greater
availability can support privacy by letting individuals access correct records.
On-demand resource capacity can also better resilience when faced with increased
service demands or distributed denial of services, and quicker recovery from serious
incidents.
Backup and Recovery – The policies and procedures of cloud providers allow better
availability, faster restoration, more reliable circumstances, and off-site backup
storage and geographical compliance requirements. Cloud Service provider also

7. provisions an off-site repository for an organization’s data center for backup and
recovery.
Mobile Endpoints – Cloud clients can either have general web browsers or have
special applications thus, the cloud solution extends to client architecture, which can
be used to access hosted applications. Cloud Clients are meant to generally have a
lightweight computation that supports all kinds of devices, benefiting the
productivity of the mobile workforce.
Data Concentration – For smaller and mobile devices, the public cloud may be of
lesser risk to data than the data being dispersed on large computers, removable
media out in the field. Organizations are following their own transition to support
access to data from mobile to improve workflow management and gain operational
efficiencies and productivity benefits.
Migrating To Public Cloud Environment
Public Cloud Computing is a model for enabling resource allocation to dynamic
business workloads in a real-time and cost-effective manner. Offering resources are
a cost-effective price, and dealing with security concerns shouldn’t be the only
criterion when determining business workloads. Migrating to a public cloud
environment requires validation of the business applications and workloads in terms
of technical portability and business compliance in order to deploy them without any
complex customization.
Cloud Decision Support System – An Effective Approach to Migrate Workloads &
Processes
The Cloud Decision Support System is an approach to help the higher management
authorities and teams to automate processes and identify workloads to move to the
public cloud environment cost-effectively.
The CDSS approach automates the classification and categorization of workloads into
different categories, such as business-critical (BC) and non-business critical (NBC)
workloads to identify based on business services within the overall business function.

8. This approach also helps in assessing the public cloud providers based on features
and constraints. Moreover, CDSS provides consideration for industry
compliance/requirements and the price model for hosting the workloads on a
pay-per-use basis.
