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.
Cloud-based solutions are accessible from anywhere with an internet connection, facilitating remote team collaboration and remote work scenarios.
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.
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.
Back-Up and Restore Data
When data is stored in the cloud, retrieving and recovering backups becomes easier. This process can be time-consuming if done on-premises.
One of the benefits of cloud computing is its ability to deploy your system quickly. This means that once you make the decision to use the cloud, your entire system can be up and running in just a few minutes. However, the speed of deployment will vary depending on the technologies utilized in your business.
Cloud providers offer a wide range of managed services, reducing the burden of infrastructure management and enabling organizations to focus on core business activities.
Innovation and Experimentation:
Cloud platforms provide tools and services for experimenting with new technologies, fostering innovation, and accelerating time-to-market for new products and features.

Cloud providers handle software updates, patches, and maintenance, ensuring applications and services run on the latest versions and are secure.
Cloud computing optimizes resource utilization and energy consumption, leading to a reduced carbon footprint compared to traditional on-premises data centers.
Disadvantages of Cloud Computing
Here are the disadvantages or risks of using Cloud Computing.
Loss of Cloud Data and Services
Having a reliable internet connection is essential for utilizing cloud computing. Without an internet connection, accessing the cloud is impossible. Typically, cloud data and services can be accessed through the Internet. The speed at which you can access these services and data depends on your internet connection speed. Losing your internet connection will result in a loss of access to cloud data and services.
When using cloud computing, it’s crucial to consider the potential for downtime. The servers or network at the cloud service provider’s end may experience issues such as power failures, weak internet connectivity, or service maintenance, resulting in loss of access to your cloud data and services. However, cloud service providers offer Service Level Agreements (SLA), which guarantee 99.9% uptime. In the event that they don’t meet this agreement, you will receive compensation.
Performance Can Vary
When working in a cloud environment, your application runs on a server that also provides resources to other businesses. If your tenant exhibits greedy behavior or experiences a DDOS attack, it could impact the performance of the shared resource.
Storing sensitive data in the cloud raises security and privacy concerns, especially in public cloud environments. Organizations need to ensure proper security measures are in place.
It’s important to consider the security risk when using cloud computing services. It’s crucial to understand that by adopting cloud technology, you’ll be sharing your company’s sensitive information with a third-party provider. Hackers could potentially access this information, so it’s important to proceed with caution.
By storing your data in the cloud, you rely on the cloud service provider to keep your business data secure. Providers such as Microsoft Azure and Amazon Web Services devote significant resources and funds to enhance cloud security. However, placing your data in the cloud rather than keeping it in-house still poses security risks.
It’s important to realize that storing your data in the cloud means that you are entrusting your data protection to your cloud service provider. The security of your data is only as good as the security measures implemented by your provider. Nevertheless, there are some best practices that can help minimize security risks, such as encryption, two-factor authentication, auditing, and regularly reviewing and rotating access keys and credentials.
Compliance and Legal Risks
When moving to the cloud, it is important to consider compliance risks. Compliance and legal risks are not a concern if you are storing personal data such as emails or photos. However, organizations dealing with financial, healthcare, credit card, or other regulated data are responsible for protecting that information by law. It is crucial to know where the data is stored, who has access to it, and the measures in place to safeguard it. Numerous local and international regulations must be adhered to, including GDPR and HIPAA.
Several cloud storage service providers, such as AWS, Microsoft Azure, and Google Cloud Platform, have bandwidth usage limits for their users. If your organization exceeds these limits, you may face substantial additional charges.
