Why is Cloud Computing Important these Days?

Before Cloud computing, organizations had to store all of their data and resources on their own hard drives and servers. The larger the business, the more storage was required. This method of handling data was not scalable in terms of speed and reliability. However, Cloud computing provides a significant shift from how organizations have traditionally handled IT resources and data. In this article, we will dig into why cloud computing is so important these days and its benefits.

What is Cloud Computing?

Cloud computing is the provision of computing services that range from servers to storage, databases, analytics, and intelligence via the Internet (the cloud).

There are five essential characteristics of cloud computing, according to the National Institute of Standards and Technology (NIST) U.S. Department of Commerce:

  1. On-Demand Self-Service: Server time, network storage, and other computing services can be requested and provisioned automatically, without the need for manual/human setup and configuration.
  2. Broad Network Access or Internet Access: Business capabilities are available across the network, and users from all over the world can "plug into" the data and applications through an internet connection at any time and from any location.
  3. Resource pooling: A single application is shared by multiple users. Rather than building a duplicate of the application for each user, numerous users, or "tenants," can customize it to their individual needs.
  4. Rapid elasticity: Platforms built on the cloud are adaptable. As demands change, an organization's resource utilization levels can be simply scaled up or down.
  5. Measured service: Typically, an organization only pays for the cloud services it uses, and, as requirements change, is able to lower operational expenses, and run technical infrastructure more efficiently."Consider how a utility company tracks how much water, electricity, or gas is consumed and charges accordingly. The cloud is similar.

Why Is Cloud Computing Important?

Businesses are turning to cloud computing services for:

Cost Saving

Cloud computing reduces the upfront costs of purchasing hardware and software, as well as the costs of building up and running on-site datacenters—server racks, the round-the-clock electricity for power and cooling, and IT experts to manage the infrastructure.


Cloud computing allows businesses to quickly access a wide range of technologies, allowing them to develop faster, and build anything they can envision. Organizations can instantly spin up resources they need to revolutionize their business, including storage, databases, Internet of Things (IoT), machine learning, data lakes, analytics, and much more.


Many cloud providers such as Google Cloud, Amazon Web Services, Digital Ocean, and so on offer a comprehensive set of policies, technologies, and controls to assist organizations to enhance their entire security posture and protect their digital assets and infrastructure against cyberattacks.


Cloud computing eliminates the need for enterprises to over-provision resources/computing services in advance to manage future peak levels of commercial activity. Instead, they can provide the exact amount of resources they require. Then, when the business’s needs change, scale these resources up or down to immediately expand or shrink capacity.

Global Scope & Speed

Cloud computing services provide self-service and on-demand computing resources, allowing businesses to deliver large amounts of computing resources in minutes, generally with just a few mouse clicks, giving them a lot of flexibility and relieving capacity planning strain.

Also, it has the capability to provide the appropriate amount of computing services or resources required at the precise geographic location.


Most cloud computing services are delivered through a global network of secure data centers that are updated regularly with the current generation of fast and efficient computing hardware. This has various advantages over a single corporate datacenter, including lower application network latency and greater economies of scale.

In addition, cloud computing eliminates the need for hardware configuration, software patching, and other time-consuming IT administration tasks, allowing IT professionals to focus on more critical business objectives.

Reliability, Data Backups, and Recovery

Data on the cloud is in duplicates across numerous redundant sites on the network, making data backup, disaster recovery, and business continuity easier and less expensive.

Also, cloud computing allows access to updated features without an on-site infrastructure upgrade.

What are the different types of cloud computing?

Organizations must first choose the type of cloud deployment or cloud computing architecture that best fits their business requirements to implement their cloud services.

Typically, a cloud service can be deployed in one of three ways: public cloud, private cloud, or hybrid cloud.

  1. Public cloud: The most common type of cloud computing deployment is public clouds, which have cloud resources (such as servers and storage) that are owned and maintained by a third-party cloud service provider and distributed over the internet. In a public cloud, the cloud provider typically owns and manages all hardware, software, and other supporting infrastructure. Microsoft Azure, Google Cloud, Amazon Web Services (AWS), and others are examples. Multiple organizations share the same infrastructure, storage, and network devices as cloud "tenants," and they use a web browser to access services and manage their accounts.
  2. Private Cloud: A private cloud is made up of cloud computing resources that are only used by one company or organization. The private cloud can be physically installed on-site at your organization's data center or hosted by a third-party service provider. However, in a private cloud, the services and infrastructure are always kept on a private network, and the hardware and software are dedicated entirely to your organization. Government agencies, financial institutions, and other mid-to large-size enterprises with mission-critical activities that want more control over their environment frequently use private clouds.
  3. Hybrid Cloud: A hybrid cloud is a type of cloud computing that incorporates both a private and public cloud. Data and apps can travel between the two environments thanks to hybrid clouds. Due to business imperatives such as meeting regulatory and data sovereignty requirements, maximizing on-premises technology investment, or addressing low latency challenges, many organizations opt for a hybrid cloud option.

What are the different types of Cloud Computing Services?

Cloud services are Infrastructure, platforms, and software that are hosted by third-party providers and made available to consumers via the internet.

Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) are the three basic categories of as-a-Service solutions. Each allows the transfer of user data from front-end clients across the internet, to the cloud service provider's servers.

  1. Infrastructure as a Service (IaaS): Infrastructure as a Service (IaaS) is a cloud computing service that allows businesses to rent or lease servers in the cloud for computing and storage. Also, users can run any operating system or application on the rented servers without incurring the fees of server maintenance and operation. Another benefit of Infrastructure as a Service is that it allows clients to access servers close to their end consumers. IaaS scales up and down automatically based on demand and offers a guaranteed service-level agreement (SLA) in terms of availability and performance. It eliminates the need for data centers to manually provision and manage physical servers.
  2. Platform as a Service (PaaS): Platform as a Service (PaaS) is a cloud computing setup that assists businesses in implementing a cost-effective cloud-based approach. Customers can use PaaS to develop, run, and manage applications without having to construct and maintain the cloud infrastructure required to develop and launch the application.
  3. Software as a Service (SaaS): Software-as-a-Service (SaaS) is a subscription-based software licensing model in which the software is hosted on external servers rather than in-house servers. Typically, SaaS is accessed via a web browser. Users log in with their username and password. Instead of installing the software on their own computer, users can access the program through the Internet. In addition to cost savings, time-to-value, and scalability, SaaS provides the benefits such as:
    Automatic upgrades: With SaaS, you can take advantage of new features as soon as they are released by the provider, rather than needing to plan an on-premises upgrade.
    Data loss protection: Since your application data is stored on the cloud, you will not lose data if your device crashes or malfunctions.

What are the uses of cloud computing?

Even if you don't realize it, you are using cloud computing right now. If you use an online service to send an email, edit documents, stream movies or TV, listen to music, play games, or store photos and other files, cloud computing is certainly at the heart of it all. Although cloud computing services are only a decade old, it is already commonplace for startups, large enterprises, government agencies, non-profits, for

  • Creating cloud-native applications: cloud computing may be used to easily build, deploy, and scale web, mobile, and API applications. Containers, Kubernetes, microservices architecture, API-driven communication, and DevOps are examples of cloud-native technology and techniques.
  • Storing, backing up, and recovering data: cloud computing is used to efficiently transfer business data over the Internet to an offsite cloud storage solution that's accessible from any location and device to protect business data on a large scale.
  • Streaming audio and video: With high-definition video and audio that is distributed globally, you can connect with your audience anywhere, at any time, on any device using cloud computing.
  • On-demand software delivery, also known as software as a service (SaaS), allows businesses to provide consumers with the most recent software versions and updates.
  • Reducing application development, testing time, and cost.
  • Analyze data: businesses may synchronize data from different teams, divisions, and locations. They can leverage cloud technologies like machine learning and artificial intelligence to discover insights that can help them make better decisions.

What about Cloud security?

Security issues can be a barrier to embracing cloud computing, particularly public cloud services. However, in response to demand, cloud service providers' security is steadily outstripping on-premises security solutions.

Maintaining cloud security requires procedures and skills that are different from the traditional IT framework which involves purchasing, installing, and servicing your IT devices on-site. Cloud security practices include:

  • Security is a shared responsibility: In general, the cloud provider is responsible for cloud infrastructure security, whereas the customer is responsible for data security in the cloud. However, it's also critical to distinguish between private and public third parties when it comes to data ownership.
  • Data encryption: While data is at rest, in transit, and in-use, it should be encrypted. Customers who use the cloud service must have complete control over their security keys and hardware security module.
  • User identity and access management: Customer and IT teams need complete visibility and awareness of the network, device, application, and data access. It enables the organization to watch for signs of intrusion and block unwanted access.
  • Collaborative management: Communication between IT, operations, and security teams, as well as clear, understood protocols, ensures secure and long-term cloud integrations.
  • Monitoring security and compliance: To retain visibility of all data exchanges between public, private, and hybrid cloud environments, start by establishing the regulatory compliance standards applicable to your industry and setting up active monitoring of all connected systems and cloud-based services.

In Summary

Cloud computing is transforming business systems and practices worldwide. Understanding the differences between different forms of cloud computing and determining which one is best for a developing company is critical.

Finally, cloud services will undoubtedly create new options for enterprises trying to innovate and drive business results as they become more widely available.
