Cloud computing is the use of cloud-based services for storing, processing, and transmitting data. It refers to any on-demand computing environment that has a significant investment in infrastructure, such as data centers and networks.
Cloud computing came about with some drawbacks of traditional computing. The two largest drawbacks were privacy and security. In the past, companies attempted to minimize the risk of identity theft by storing all their information in a centralized server that was kept in-house (on site). But this restricted the ease of access to data. But with the cloud, any data can be accessed online without the worry of its security. In fact, the cloud computing architecture makes it possible to access a shared pool of adaptable computing resources from anywhere, at any time, and on-demand.
With low operating costs, scalability, and flexibility associated with it, Cloud computing is gaining popularity worldwide. For that reason, top cloud computing companies in India and worldwide have started investing in the cloud for storing and managing their data.
Who is using Cloud Computing?
A recent study found that most companies are moving their networks to the cloud. This has become an important trend in many industries like healthcare, agriculture, finance, public administration, and more. Cloud computing is a big part of future technology development and is becoming an essential component of business operations.
Cloud Computing Deployment Model
There are three major deployment models for Cloud Computing: private, public, and hybrid.
- Private Cloud Model: The most common deployment model is the private model. This is where a company uses a private cloud to host its data and applications.
2. Public Cloud Model: It is the one that is offered by vendors such as AWS, Azure, etc. In this model, data is stored in a cloud datacenter on a shared basis and can be accessed over the internet using authenticated Ids and passwords.
3. Hybrid Cloud Model: The hybrid model combines elements of the private and public models.
Types of Cloud Computing
Three main types of cloud computing solutions are as follows:
Infrastructure-as-a-Service (IaaS): IaaS or Infrastructure-as-a-Service is a popular type of cloud service that allows you to host your own servers on the cloud and allocate the necessary resources like CPU power and storage space.
Platform-as-a-Service (PaaS): PaaS or Platform-as-a-Service is another type of service that allows you to build customized software without having to invest in hardware and operating system.
Software-as-a-Service (SaaS): SaaS or Software-as-a-Service is arguably the most popular service because it helps you use pre-built applications with just a few clicks on your computer or mobile device. It is generally based on a pay-as-you-use model.
Benefits of Cloud Computing
Cloud computing is a technique that allows people to access shared resources over the internet. These resources are typically software, data, and applications. In other words, it is a kind of network-accessible resource which has been provided as a service.
Benefits of cloud computing include:
- Improved speed (user’s data is always in the cloud and accessed remotely)
- Better portability (users can access their data from any location or device)
- More accessibility (the same software can be used by multiple users)
- Reduced need for a company to maintain large IT infrastructure
- Increased flexibility
- Enhanced Security and privacy
- Reduced maintenance costs
- Easily Scalable
