The global cloud computing market is expected to reach $1.614 trillion by 2030. This substantial growth in cloud computing adoption reflects its pivotal role as the backbone of many organizations and applications, largely due to the benefits it offers, such as cost reduction, scalability, accessibility, and efficiency.
To better understand this shift, consider the analogy of cloud computing to the transition from owning to renting a car. Just like renting allows individuals to avoid the burdens of maintenance and ownership while enjoying flexibility and lower costs, cloud computing offers businesses the ability to access computing resources without significant investment in infrastructure, allowing for greater agility and resource optimization.
However, like all other forms of technology, cloud computing also comes with its fair share of risks, such as data loss, reduced control, and confidentiality breaches.
In this article, we demystify the advantages and risks of cloud computing in detail, beginning with understanding what cloud computing is, with examples and its types.
Imagine companies making huge capital expenditures to buy physical servers, networking equipment, and storage disks. To make these purchases, organizations need to guess their peak traffic needs, spending significant time, money, and resources, which may often go to waste, as companies tend to buy more than they consume day-to-day.
This is the problem cloud computing solved. Instead of purchasing hardware, companies can rent computing power from cloud service providers, such as Google, AWS, or Microsoft. This converts their enormous capital expenditures into a manageable operational expenditure or a monthly bill, eliminating the guesswork, waiting times, huge costs, and wasted resources.
To illustrate, consider a small bakery in town. By using cloud-based inventory management tools, the bakery can track inventory levels in real-time and receive alerts when stock is low, ensuring they never run out of essential ingredients. Additionally, cloud services can streamline their sales operations by offering point-of-sale solutions that integrate with their accounting software, ensuring accurate and up-to-date financial records without the need for complex software installations or maintenance on local devices.
Hence, we can define cloud computing as a technology that lets you store and access data and applications over the internet instead of your PC’s local server or hard drive.
Moreover, the “cloud” in cloud computing is a global network of remote servers that stores and processes data for other computers and devices.
A simple example of cloud computing is Google Docs. You can access Google Docs anywhere and anytime through the internet, allowing you to work on presentations and spreadsheets at your convenience, enhancing your productivity.
In a more technical example, AWS Lambda allows developers to run application and back-end service code without provisioning or managing servers. This pay-as-you-go model helps them accommodate real-time changes in data usage and storage.
While on-demand self-service, broad network access, resource pooling, scalability, and pay-as-you-go are the core characteristics of cloud computing, it has three types. Let’s explain them next.
The three cloud computing models include public, private, and hybrid clouds. The public clouds are managed by third-party providers, such as Microsoft Azure, Amazon Web Services (AWS), or Google Cloud Platform. On the other hand, private clouds are dedicated to one organization. The hybrid cloud combines the public and private clouds.
Accessible to anyone who has an internet connection, public clouds offer a wide range of services, ranging from storage to applications, over the internet.
Its pay-as-you-go model makes it ideal for startups and small businesses, allowing them to expand their resources without huge investments.
Unlike public clouds, the private cloud data and services are maintained on a private network, ensuring higher control and security.
However, since it involves a higher cost, it is more suitable for large enterprises and organizations that deal with sensitive data, for example, financial institutions.
Combining the advantages of cloud computing for private and public clouds, the hybrid cloud lets organizations store sensitive data in private clouds and use the public cloud for less-sensitive tasks, allowing them to balance security and accessibility.
This greater flexibility and scalability make hybrid clouds a better choice for enterprises needing customized cloud computing for cost optimization, security, and performance according to their individual needs.
On that note, the cloud computing services can also be of four types. The four types of cloud computing include Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Software as a Service (SaaS), and Function as a Service (FaaS).
Infrastructure as a Service (IaaS) lets you access IT tools, such as storage, virtual computers, and networks, via the internet, without buying or managing physical hardware, while paying for only what you use.
Platform as a Service (PaaS) is where you can develop, test, and run applications through the software and hardware tools offered by third-party providers, such as Amazon Web Services (AWS).
Software as a Service (SaaS) lets you use software over the internet without having to install it on your computer. Another company hosts the software (for example, Google hosts Google Docs), and you can log in to the software through your browser and use it.
Function as a Service (PaaS) lets you run code in response to events without having to manage the complex infrastructure. You can simply write and upload the code; the cloud provider will run the code only when required, and you will pay only when your code runs.
In addition to this cost saving, there are several other benefits of cloud computing. To start exploring these benefits, individuals and businesses can sign up for a free trial with major cloud service providers like AWS, Google Cloud, or Microsoft Azure. Additionally, consulting with a cloud service provider can offer tailored advice to maximize these advantages based on specific business needs.
The advantages of cloud computing include cost-effectiveness, high speed and agility, remote data and application access, effortless scalability, high performance, and efficiency.
Unlike traditional computing setups, cloud computing does not require substantial investment in software licences, hardware, and IT personnel. Moreover, since the service provider bears the major financial burden, and businesses only pay for the resources they consume, cloud computing is a cost-effective option, especially for startups and small businesses.
The on-demand cloud computing services help businesses quickly scale their resources based on demand, leading to faster application development, testing, and deployment. Moreover, businesses can adapt swiftly to market changes, try new ideas and innovations without worrying about the constraints of traditional infrastructure.
Remote accessibility is one of the major advantages of cloud computing. It allows users to access their data and applications from anywhere, anytime, with an internet connection, leading to seamless real-time collaboration and enhanced productivity.
Cloud computing lets businesses scale their resources up or down based on changing business requirements. This flexibility allows the ready availability of resources when the demand is high and prevents over-provisioning and high cost when the demand is low. It makes cloud services especially beneficial for businesses that experience sudden demand spikes, without quality compromises or additional expenses.
Cloud-based apps and services do not experience much downtime, resulting in uninterrupted business operations. Moreover, the world-class data centres and hardware of cloud service providers lead to reliable and top-notch performance for hosted services.
Moreover, if you wonder how secure cloud computing is, cloud services enhance data security with their high availability and redundancy measures for excellent data backup and disaster recovery.
Cloud computing relieves businesses of infrastructure management, software updates, security patches, and hardware maintenance, freeing up resources and allowing businesses to use their time, energy, and manpower on their core business and strategic initiatives, making them more efficient to enhance their growth and competitiveness.
While cloud computing has several benefits, there are also many cloud computing risks.

The potential risks or disadvantages of cloud computing include data loss, security concerns, reduced control, increased complexity, and confidentiality breaches.
Cloud computing requires businesses to trust third-party providers with their sensitive information. It leaves them vulnerable to data loss if the provider encounters breaches, system failures, or other problems due to hardware malfunctions or cyberattacks, leading to reputational damage, financial losses, and, if applicable, legal penalties.
Cloud computing may leave several loopholes for bad actors to exploit and steal your data, as data resides on external servers and is accessible through the internet, increasing the chances of data theft, unauthorized access, and compromised privacy.
Businesses need to entrust their data and applications to third-party cloud service providers, as they depend on these services for security, uptime, and service continuity. This may lead to businesses losing some control over their data and apps. If the provider experiences downtime or discontinues services, it may disrupt operations, hampering productivity and resulting in potential financial loss.
Small organizations with limited IT expertise may find it difficult to migrate to the cloud and manage cloud-based resources. It may be challenging for them to select the most suitable cloud model, optimize resources, perform data integration, and manage cloud-native apps, which may cause potential inefficiencies, misconfigurations, and security vulnerabilities.
Breached confidentiality is not uncommon in cloud computing, especially for businesses that deal with sensitive data. These businesses share data with third-party providers, increasing the risk of unauthorized access to confidential information.
While these are risks associated with cloud computing, there are also ways to manage these risks.
