Cloud computing means that whatever hardware or software you use sitting on your desktop computer or on your company's network is made available to you as a service, easily accessible over the Internet.
These services include data storage, servers, databases, networking and software. Data is stored on physical servers managed by cloud service providers.
In cloud computing, computer resources such as storage and computing power are the services with the highest demand. Instead of storing your files on your computer's hard drive, if you store them in the cloud, you can access those files from anywhere, all you need is an Internet connection.
Cloud-hosted services can be divided into two categories, which we call Infrastructure-as-a-service or IaaS, and Software-as-a-service, or SaaS.
According to the deployment model, there can be three types of cloud computing which are called private, public and hybrid. Moreover, the cloud can be divided into two layers i.e. front-end and back-end. The layer with which users interact is called front end. All users access the data stored on the cloud with the help of this layer.
The layer which is made up of hardware and software like computers, servers, central servers, databases etc. is called back end layer. This layer is the core part of the cloud which is responsible for storing information securely.
To ensure smooth communication between connected devices through cloud computing, central servers use software called middleware. which acts as a bridge between database and applications.
Types Of Cloud Computing
Cloud computing can be divided into three types based on the employment model which are private, public and hybrid cloud. And based on the services that the cloud provides, we can divide it into three categories, namely Infrastructure-as-a-service (IaaS), Software-as-a-service (Saas) and Platform-as-a- service (Paas).
In a private cloud, computing services for a specific organization are provided over a private IT network.
A private cloud, also known as an internal, enterprise, or corporate cloud, is typically managed within an organization and is not accessible to anyone outside that particular organization.
A private cloud provides all the same services as a public cloud, but with better security, customization and control.
Private clouds provide a high level of security through company firewalls and internal hosting to ensure that an organization's sensitive data is not accessible to a third party.
However, the downside to a private cloud is that the organization becomes responsible for the organization and maintenance of the entire data center, which can require a lot of resources.
Computing services that are provided by a third party are called public clouds. Unlike a private cloud, services on a public cloud are available to anyone and can be used or purchased by anyone. These services can be either completely free or pay as per the amount of resources used.
A cloud service frees any business from the hassle of purchasing and then maintaining the computer hardware and software assets used in their company. Because all these assets are the responsibility of cloud service providers and they also maintain these resources. In this way, the capital spent on buying digital assets of companies can be saved.
Public Cloud also provides flexible services of RAM and Bandwidth to provide flexible services of storage.
A hybrid cloud combines the features of both public and private clouds. This model, which combines the features of private and public cloud, transforms itself into public or private cloud according to its needs and computing and other resource requirements to share the workload.
As computing and processing demands continue to change, hybrid cloud enable businesses to move their company's computing infrastructure to the public cloud. Along with this, it also ensures that no third party can access the company's data.
We know that based on the service model we can divide the cloud into three types IaaS, PaaS, and SaaS. Let's know about them now.
IaaS is a type of cloud in which cloud service providers provide servers, storage, and networking services to you through a private interface. This service does not require the user to manage the cloud infrastructure, but gives full control over the storage, operating system and installed apps.
In IaaS, a third party hosts the hardware, servers, storage and other infrastructure components instead of the customer. The third-party vendor also manages all of the user's applications and their backups.
PaaS is a type of cloud computing that provides a development and deployment environment in the cloud that allows users to develop and run applications without the complexity of building or maintaining the underlying infrastructure.
It provides users with resources to develop cloud-based applications. In this service, the user purchases services from their vendor (cloud services provider) on a pay-as-you-go model and then accesses them over a secure connection.
In PaaS, users don't need to manage their core infrastructure like network, servers, storage and operating system etc. and they have full control over the installed applications.
It enables companies to focus on deploying and managing their applications by freeing them from the responsibility of software maintenance, planning, and resource procurement.
SaaS allows users to use a vendor's software on a subscription basis. This type of cloud service does not require users to install software on their computers. Instead, the application is hosted on a remote cloud network that users can access through the web or an interface.
In the SaaS model, the service provider manages the hardware, middleware, application software and security. This service, also known as hosted software or on-demand software, helps companies streamline the maintenance and support of these software.۔
Benefits Of Cloud Computing For Large Enterprises
The main reason for the rapid growth of cloud computing is its numerous advantages. Due to this, companies do not need to set up an entire physical IT infrastructure and can save costs and resources. Let's see what benefits the cloud provides us:
- Lesser Cost: IT systems require large capital to maintain, which the cloud helps reduce. By using the resources provided by a cloud service provider, companies no longer need to purchase expensive infrastructure, which reduces their costs.
Because cloud services work on a pay-as-you-go model, companies pay only for the services they use. It does not use any additional services and further reduces costs for companies.
- Scalability: The cloud enables organizations to scale their workforce from a few to thousands in a very short period of time. This enables companies to scale up or down storage requirements as needed, making companies flexible.
- Flexibility & Collaboration: Since data can be accessed from anywhere on the cloud, employees of companies have the convenience of being able to sit and work from anywhere. With the help of cloud you can create your virtual office anywhere.
- Continuity Of Business: The cloud securely stores and protects your data in the event of an outage or crisis. Saving data in such a way makes it possible to resume business immediately whenever the entire system is restored.
- Competitive Edge: The cloud takes care of various business aspects, such as maintaining IT infrastructure, licensing software, or training personnel to manage your data. In this sense it gives you an advantage over your competitor as the resources you spend on these aspects of the business are less than your business rivals.
Cloud computing has almost completely changed the world of IT. In the future, the cloud will bring many new and better ways to create products and services, better serve customers and make new discoveries.
Business leaders who embrace the potential of cloud computing are sure to gain a competitive edge in this changing landscape – in the tools and software they choose, in the cultures they create, or in what they do. In Vali business strategies.
