Cloud computing refers to the storage and access of data over the internet. Unlike traditional methods, data is not stored on the hard disk of your personal computer. Instead, it can be accessed from a remote server. Within this, keep in mind, let us proceed and understand the advantages and disadvantages of Cloud Computing.

Advantages of Cloud Computing

Here are the advantages of Cloud Computing.

Reduced IT Costs

The most significant benefit of cloud computing is cost reduction or savings. It allows us to save a significant amount of money on IT expenses since there is no need for physical hardware investments. The cloud service provider takes care of purchasing and managing the equipment. Let us understand how it saves big money in detail.

If you have a business application that you want to make available to online users, you used to have to purchase a physical server along with all the necessary infrastructure to host the application. This was costly due to the high expense of servers, resulting in a large initial capital expenditure for organizations. However, with the advent of Cloud Computing, this has changed.

In order to keep the server running smoothly, we require a secure server room. The server needs to be set up and configured, connected to UPS and the network, and equipped with a proper cooling system. Additionally, the server operating system, anti-virus software, Database server, and any other dependencies needed for the business application (such as the .NET framework or a web server like IIS) must be installed during the initial setup process.

As part of our responsibilities, we must ensure that our servers function properly and maintain good condition. This includes downloading and installing any available updates or security patches on the dedicated server machine. Additionally, in the event of a hardware or power failure, natural disaster, or other emergency, we are responsible for replacing any failed hardware. We also need to manage database backups, implement disaster recovery plans, and set up failover systems. We require a specialized IT workforce for initial setup and ongoing maintenance to accomplish this. It’s important to note that organizations face significant operating expenses on a monthly basis due to these requirements.

By moving to the cloud, organizations can reduce their capital expenditure (Capex) and operating expenses (Opex). They no longer need to invest large sums of money in physical servers, IT infrastructure, specialized IT personnel, or server rooms/data centers. Instead, they can use cloud infrastructure and pay a monthly fee for the required resources and services.

Pay as You Go

When using the cloud, payment is based on usage. This means that you only pay for what you use, similar to how you pay for your post-paid mobile, electricity, and water bills. You will pay more if there is a high demand for your application and you require more cloud resources, such as storage or computing power. Conversely, you will pay less if your business has lower demand and requires fewer resources. In short, cloud resources are metered, and you are only charged for what you use.

Scalability and Flexibility

The cloud offers a variety of options for scalability and flexibility. By simply clicking a button, you can increase the cloud resources, such as memory, processing power, and storage. You can even automate this process by setting a limit. For instance, if you reach 90% of the current storage capacity, you can add another 100 GB to the storage. Similarly, if you are not utilizing the resources, you can scale them down and set a threshold limit for them. With the cloud, you never have to worry about running out of resources. You can easily scale up when you need more power and scale down when you don’t. Additionally, there’s no need to bear the burden of purchasing and installing expensive upgrades since your cloud service provider, such as Azure or Amazon Web Services, handles it all for you.

Global Accessibility

Cloud-based solutions are accessible from anywhere with an internet connection, facilitating remote team collaboration and remote work scenarios.

Business Continuity

Storing your data on your own server poses a risk in the event of hardware failure, power failure, natural disaster, or crisis, resulting in permanent loss of data. This can have a severe impact on business operations. However, storing your data in the cloud offers a solution to this problem, as networked backups ensure that data is not lost in the event of such occurrences.

Automatic Updates

When you host your applications on your own server, it becomes your responsibility to download and install software updates and security patches, which can be both tedious and time-consuming. However, if you choose to use the cloud, the service provider will automatically install all necessary security patches and software updates for you. All you need to do is pay a small monthly fee.

Automatic Software Integration

When you use cloud-based software, integration happens automatically. This means you don’t have to make extra effort to customize or integrate your applications to fit your preferences.


Cloud computing offers great reliability, providing instant updates on any changes made.

Mobility and Collaboration

Both on-site and remote employees have convenient access to all cloud services. This means that teams and team members can easily access, edit, and share files from anywhere and at any time. Everything is stored in the cloud, allowing for better collaboration and teamwork. All that is required is an internet connection.


Using the cloud for resources and services is mostly self-service. With a little bit of learning, you can easily obtain, configure, and utilize cloud resources and services. For example, if you require a server to host your application, there is no need to consult IT experts to determine the size and speed of the server. You can easily obtain a virtual machine from the cloud and host your application with just a few clicks. If you need more processing power, you can scale up, and if you don’t need as much, you can scale down again with a few simple clicks. In our upcoming articles, we will show you how easy it is to create VMs, containers and scale resources up and down.

Unlimited Storage Capacity

With the cloud, you have access to limitless storage space. You can easily increase your storage capacity at any time for a small monthly fee.
