All You Need To Know About Cloud Computing

You might have heard about Cloud Computing from your friends or colleagues. It wouldn't be wrong to say that Cloud Computing has transformed our IT infrastructure into a helpful tool. Cloud Computing replaces physical computer resources with software and network-based premises. In this article, we will discuss cloud computing and the types of cloud computing platforms.

What is Cloud Computing?

In simple terms, Cloud Computing means shifting your daily computation tasks over the internet instead of a physical hard drive. With Cloud Computing, people can store their valuable data and access them whenever they want from the Cloud. It is riskless, more popular, and an easy solution to reduce workforce pressure on employees. You can get Cloud services on a pay-as-you-go basis over your internet, or you can get on-demand delivery of these services. Cloud Computing includes servers, databases, software, storage, speed, security, and analytics over the internet. It's designed to be scalable, so you can increase or decrease a Cloud's scale according to your wish. Cloud Computing is better, less costly, and runs your business infrastructure more efficiently.

How does it Work?

Keeping a massive track record of your important files and documents can become a troublesome business. If the data you wish to store for backup is in terabytes, keeping it in hard drives would be costlier. So, companies prefer Cloud Computing instead. Your company does not need to own any physical infrastructure or data centers. Instead, they can implement Cloud Computing in the office by renting it. The work is simple. Your company connects to a Cloud Drive storage where you can upload your work, update it or retrieve it any time. There are multiple Cloud Computing services companies can avail of. Cloud can be multi-purpose, and you can implement it for networking, backup, use standard office apps, AI Natural language processing, and many other similar services.

The Types of Cloud Computing Platforms

There are three main types of Cloud Computing platforms. Each of them has a different architecture and implementation. These are:

  • Public 

  • Private

  • Hybrid


Public Cloud

Public Clouds are operated and run by third-party providers. They offer their computing resources in the shape of storage and server. In other words, a Public Cloud is sold on demand.  In Public Cloud Storage, the customers only pay for the bandwidth and storage they consume, making it economical. The best examples are Google Cloud, Amazon Web Services, and IBM.

Private Cloud

A Private Cloud is dedicated and designed for a particular organization or individual and only accessible by the owners. Private Cloud is more secure and offers better service delivery than Public Cloud. If your organization has to save some classified data, intellectual property, personally identifiable information, or something of that sort, then Private Cloud would allow full-fledged privacy and protection. The best examples are OpenStack and VMware.

Hybrid Cloud

Hybrid Cloud is both Public and Private. It is a combination that allows data and other resources to be moved between Public to Private Clouds. A Hybrid Cloud is considered the most flexible with more deployment options and added security. A Hybrid Cloud creates a unified and automated environment like that of the Public Cloud and maintains its control over privacy and data protection at the same time. One of the best examples of Hybrid Cloud is TrueNAS. 

Types of Cloud Computing

Now that we learned about Cloud Computing platforms, it is time to know about their types:

  • SaaS

  • PaaS

  • IaaS

Software-as-a-Service

SaaS provides licensing of a software app. It delivers software apps over the internet with a subscription. The customers buy these licenses through a pay-as-you-go basis or on-demand. In simpler words, SaaS provides applications that are called web services. Users can use SaaS from any device or location via the internet. The users also gain access to databases. A prominent example of SaaS is Nextcloud Hub, Twake, and EGroupware

Platform-as-a-Service

PaaS refers to when Cloud services are supplied on-demand for managing software applications, their development, testing, and delivery included. Developers keen to create web and mobile apps quickly prefer PaaS. It makes it easier for them to set up without managing the background infrastructure like network, storage, database, and servers. OpenShift and CloudFoundry are some common examples.

Infrastructure-as-a-Service

IaaS is the most commonly known Cloud Computing Services. You can rent IT infrastructures like virtual machines, OS, servers, storage, and other services from the Cloud Provider and pay-as-you-go. IaaS is easily customizable and highly preferred by small and large organizations for their workload needs. CloudStack and Nimbus are a few of the best examples of IaaS platforms.

Cloud Computing Challenges

Here are some highlighted challenges that Cloud Computing can face:

Data Privacy

Cloud Computing still has issues with data breaches and leaking of sensitive information.

Costly Proprietary Cloud Computing Software 

The payment models are tough and unpredictable.

Barriers to Training and Development

Many companies lack the resources to update their Cloud and train their employees.

Data Migration Strategy

Migrating data to other Cloud infrastructure is anything but smooth.

Conclusion

Cloud Computing is an ever-emerging field. It shall continue to advance. The challenges it faces are significant, but this wouldn't be an issue anymore in the coming days with constant up-gradation.
