What is Cloud Computing? Everything You Need to Know in 2023

Data has always ruled businesses. And technology has developed in leaps and bounds toward finding effective methods to store and access data. It began with papyrus leaf, then paper, and with the advent of computers, data started being kept in disk drives. We even believed that data stored on servers and drives were the most efficient data storage mechanism. But this thought was overridden by cloud computing technology. 

Here, the word cloud means the Internet, and it’s more like a virtual server where data can be stored and retrieved remotely through the Internet. Data storage was the main intention in the initial stages of Cloud Computing. But with technological advancements, cloud computing companies provide various other services like networking, software, AI, databases, and applications. 

Before cloud storage happened, big industries had to manage their data server centers. Cloud services have made it easy as anyone can rent the space on the server according to one’s needs. 

Benefits of Cloud Computing 

Salesforce was the first organization to start cloud computing services in 1999. AWS followed it in 2002, and then Microsoft and Google joined in. Technology has evolved, providing several advantages to businesses, big and small.

1. Business Agility: A company that operates on a cloud server can work quickly on projects compared to those that rely on physical infrastructure. There are no time-taking server procurement procedures involved. Cloud data can be computed and implemented faster, which has increased trials on experimentations that can improve customer experience. 

2. Reduced Cost: Organizations can save on the amount spent on stacking up hardware and software. Enterprises can also bid farewell to the costs involved in setting up and operating physical data centers. The expense as a whole would be much lower than individual server set-up. 

3. Pay on the go: In cloud computing, businesses can scale up the space as and when required. Similarly, software and applications can also be added to the package on the go. This feature enables even small-scale companies to make use of cloud services. 

4. Easy Migration: Workloads can be easily transferred between organizations or cloud providers. Companies may be urged to switch to a different cloud platform for several reasons, like cost, usability, or features. 

5. Easy Accessibility: Simple examples of cloud storage are Google Drive and Dropbox. Anyone can back up files, photos, and videos without using up hardware space. They can be kept safe without the concern of loss of data. Anyone with an internet connection can use the cloud services with a subscription.

6. Data Mobility: With the remote placement of data, you do not have to carry a USB or CD to access the data. Most cloud providers have enabled users to log in through their smartphones and thus stay connected at all times. Cloud computing has also eased the remote working model. 

7. Speed & Performance: Several secure data centers are involved in cloud space, and the service provider constantly updates it with the latest technology. It reduces the network latency and thus enables vast computing to be done in a few minutes. 

8. Increased Productivity: Companies can save on the human resource spent on setting up the data centers. Cloud providers like AWS and Microsoft have certifications for specialized job roles in cloud computing. By hiring certified professionals, businesses can be assured that they have the best hands on the job. 

Things to Note about Cloud Computing 

Every technology has some downsides, and it is necessary to understand these to analyze the service.

1. Security: When more enterprises are reaching for cloud storage, security remains a significant concern. Data is encrypted, but there are still issues of data breaches, API hacks, or even loss of data due to the loss of the encryption key. 
2. Fluctuating Costs: With the usage-based pay plan, the scaling up of resources can increase the costs. Companies depend on qualified Cloud Administrators to figure out the cost concerns and plan the usage accordingly. 
3. Expertise Shortage: Being a new technology, there is an immensely high demand for skilled and certified cloud professionals. 

The top cloud providers are currently AWS, Google Cloud, and Microsoft Azure. There are also others like Apple, Salesforce, IBM, Alibaba, Oracle, etc. Businesses choose the cloud provider based on their use case, among other common factors. Reliability and security are the predominant deciding factors.
