In this era, Cloud Computing is the most authoritatively mandating, upcoming, and trending technology. Every technology has its history i.e., before the last 50 years people are storing data on floppy disk and punch cards. After 10 years they were commenced storing data in CDs, DVDs that occupy a lot of physical storage. Likely the crises commenced of storing a substantial quantity of data, then we moved on to utilize pen drives, card readers, hard disks, etc but it comes to a quandary of data integrity.
Then an incipient concept arises that is “Cloud Computing” where data authenticity, integrity, scalability, availability is highly concern. Data are stored virtually on servers i.e. BIG DATA, where both structured and unstructured data is available. Sundry frameworks are acclimated to solve the quandaries cognate to data.
This has been an incipient process for everyone located at a distance they can facilely access the software and their accommodations through cyberspace. There is no desideratum for vendors to distribute software and get It installed. This is an incipient process which is called Software as an Accommodation or SAAS. As everybody kens that substantial magnitude of data can be facilely transferred from one location to another location with the avail of the internet.
Why people have commenced transferring their data via the internet it is to maintain the celerity and time and the reliability that is gained through the internet.
Most of the people are getting discombobulated towards their contrivance so, let me explicate it very conscientiously. Cloud Computing can avail you to transit your data but your data will get stored in your desktop, computers, and laptops. Each data have to be stored in a particular database. But yes several computers who are located different locations can be interconnected by a network where these functions are performed by engineers. Here are sundry switches and servers connected accordingly.
How data is getting stored?
All these data are stored on a cloud. Cloud refers to the accommodation that can be accessed anytime with the avail of the internet. All the software and database run over the servers.
Where the cloud servers are located?
It is located at data centres. There are many companies and utilizer who don’t have to manage their physical servers by themselves and all these quandaries are minimized by cloud computing.
In cloud computing, you can access your files and application like where you are accessing your files and application on your contrivance. In other words, you can verbalize that this is your own cloud space. No essentiality to update and maintain their servers now and then. Cloud has its functionality and it auto-update itself.
Advantages of cloud computing
1. You can facilely backup and renovate your data
Once the data is there on the cloud, you can facilely access it according to your requisites and the data gets stored. As it automatically recuperates your data after getting updated.
2. Cloud has ameliorated the collaboration
The application of cloud computing has amended a collaboration to an extent, and it sanctions people to expeditiously access as per their desiderata and they can additionally share that data to their clients.
3. Frugal maintenance cost
Cloud Computing does not require any physical store and all data are stored on the server so it does not require any hardware or software maintenance cost. Cloud itself has a sizable voluminous server presented in an online platform.
4. Mobility
This is one of the good advantages of all the users utilizing Cloud Computing as they can facilely access their data utilizing desktop applications, laptop applications, tablets, and Smartphones.
5. Illimitable data storage capability
In cloud computing, there is no constraint in storing your data. Anyone can keep their data if they have. Data can be facilely stored as many as you want or it is verbalized that illimitable data are stored on the cloud. Besides storing data in the cloud, it additionally secures the information of the people to be safe and for fended.
Disadvantages of cloud computing
1. Access to internet connections
This is the prior option to access any data from the Cloud. As it requires good internet connections so that you can facilely access the data, files, folders, image, audio, and video that requires a loading time on the server. Having good internet, you can fetch data in seconds.
2. Inhibited control of access
Everybody kens that the cloud computing platform is owned and monitored by the servers. As we ken the Cloud Computing platform provides sundry accessibility of users level and then authentication level so the control is only allocated to utilizer level.
3. There is an abundance of third-party vendors that are connected to a cloud computing infrastructure due to which security issue is one of the most highly accessible quandaries because the intermediates vendors can sell out your data. There are a lot of security issues when it comes to cloud computing.
FAQ’s
1. How does Cloud Computing ensure data security?
Cloud providers implement strong security measures such as:
- Encryption – Protects data in transit and at rest.
- Access Control – Restricts unauthorized access through authentication and authorization mechanisms.
- Firewalls & DDoS Protection – Defends against cyber threats and unauthorized access.
- Regular Backups – Ensures data availability and recovery in case of failures.
2. How does Cloud VPS differ from Dedicated Servers?
| Feature | Cloud VPS | Dedicated Server |
| Cost | More affordable (shared resources) | Expensive (dedicated resources) |
| Scalability | Easily scalable | Requires manual hardware upgrade |
| Performance | Good, but shared with other VMs | High performance, dedicated CPU, RAM, and storage |
| Security | Secure, but shared infrastructure | Highest security with dedicated hardware |
3. What are the security risks associated with Cloud Computing?
- Data breaches – Unauthorized access to sensitive data.
- Lack of control – Users rely on third-party cloud providers.
- Compliance issues – Some cloud providers may not meet regulatory requirements.
- Shared infrastructure risks – Multi-tenant environments increase the risk of attacks.
4. What is the difference between Cloud VPS and Traditional VPS?
| Feature | Cloud VPS | Traditional VPS |
| Infrastructure | Hosted on a cloud environment with multiple servers | Hosted on a single physical server |
| Scalability | Easily scalable by adding resources | Limited scalability |
| Redundancy | High availability with failover support | Single-point failure risk |
| Pricing Model | Pay-as-you-go | Fixed pricing |
| Performance | Dynamic resource allocation | Fixed resource allocation |
5. What are the major security challenges in Cloud Computing?
- Data Breaches – Unauthorized access to sensitive data.
- Misconfiguration – Poorly configured cloud settings can expose data.
- DDoS Attacks – Cyber attacks that overwhelm cloud servers.
- Insider Threats – Employees or vendors misusing access.
- Third-party Risks – Untrusted cloud service providers mishandling data.
6. What is the best way to secure a Cloud VPS?
- Use Firewalls & Security Groups – Block unauthorized access.
- Enable Encryption – Encrypt data in transit and at rest.
- Implement Strong Authentication – Use MFA and strong passwords.
- Perform Regular Backups – Keep snapshots for recovery.
- Monitor Logs & Activity – Detect suspicious behavior early.
7. What are the benefits of using Cloud Storage?
Remote Accessibility – Access data from anywhere.
Scalability – Store unlimited data as per need.
Cost Savings – No physical storage hardware required.
Data Redundancy – Automatic backup to prevent data loss.
Collaboration – Share files easily with multiple users.
8. How does Cloud Computing handle Disaster Recovery?
- Automated Backups – Regular snapshots of data.
- Geo-Redundancy – Data stored in multiple locations.
- Failover Mechanisms – Auto-switching to backup servers.
- Disaster Recovery as a Service (DRaaS) – Cloud-based recovery solutions.
9. What is the role of Virtualization in Cloud Computing?
Virtualization is the backbone of cloud computing, allowing multiple virtual environments to run on a single physical machine. It improves efficiency, reduces costs, and enables on-demand resource allocation. Technologies like KVM, VMware, Xen, and Hyper-V are widely used for virtualization.
10. What is KVM Hypervisor, and why is it popular in Cloud Computing?
KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux systems. It converts a Linux host into a hypervisor, enabling multiple virtual machines (VMs) with dedicated CPU, memory, storage, and network resources.
Why is KVM Popular?
Open-source and cost-effective. Supports multiple OS types (Windows, Linux, etc.). Offers high security and performance.
