What is Cloud Computing? Here’s what you need to know

Suppose you’re the proprietor of a software development firm and thinking of expanding your scale. However, you will encounter several challenges, including a small crew, limited resources, and demand that is unpredictable. So, that’s where Cloud Computing comes in handy.

Cloud computing is the process of storing and accessing data (such as photographs, videos, documents, and other files) and applications over the internet rather than on your computer’s hard drive or mobile device’s internal storage. Clouds can be restricted to a single company (enterprise clouds) or made open to several companies (public clouds).

It refers to the delivery of on-demand computing services on a pay-as-you-go basis. Cloud computing is used by most businesses of any size or type for data backup, recovery, email, virtual desktops, testing, and other purposes.

Before you can fully comprehend cloud computing, you must first understand the differences between on-premises and cloud-based computing in various aspects.

  1. Scalability

a. On-premises: You will have to pay more merely to obtain a few options here. And once the scale is established, it is extremely difficult to reduce it, resulting in significant financial and infrastructural losses. Cloud-based

b. Computing: It allows you to only play with as much as you need, with faster and easier scaling up and down options.

2. Data Security

a. On-premises: The data security is only secured only by the physical guard or traditional IT sectors resulting in a lower level of protection.

b. Cloud-based Computing: Secured by better security with no constant need for physical security.

3. Server Storage

a. On-premises: They need a lot of space for the servers. The fuss of power and maintenance makes it worse.

b. Cloud-based Computing: It comes with a service provider who manages the servers, saving both time and money. A few of the cloud service providers are Azure, AWS, and more.

4. Data Loss

a. On-premises: If the data is lost, it is nearly hard to restore it at this premise.

b. Cloud-based Computing: They have high-level recovery measures in place to ensure that data is recovered quickly.

5. Maintenance

a. On-premises: They demand a larger workforce for hardware and software maintenance, which increases the cost.

b. Cloud-based Computing: The service provider handles the maintenance in cloud computing, which saves money and resources.

Top Cloud Service Providers & Companies of 2021

  1. Microsoft Azure

Microsoft Azure is a cloud computing service that is used for building testing deploying and managing the application. This process is done in a global network of the Microsoft-managed data center. It is a private as well as a public cloud platform.

It uses virtualization which differentiates the coupling between the operating system and CPU with the help of an abstraction layer known as a hypervisor.

This hypervisor emulates all the functionality of the physical machine such as hardware and server into a virtual one. There is numerous amount of virtual machine available and each virtual machine can run many operating. In the data center of Microsoft, there are many servers and each server consists of a hypervisor through which multiple virtual machines can operate. With the help of Azure, it is easy for developers and IT professionals to manage and deploy their applications and services.

2. Google Cloud Platform

Google cloud platform is one of the leading Cloud Computing services which are offered by Google and it runs on the same infrastructure that Google uses for its end-user products.

The Google cloud platform is basically used for Google search and YouTube. There are various services offered by Google Cloud such as data analysis, machine learning, and data storage.

The data stored in Google Cloud is secure and can access easily. It offers varieties of services from infrastructure as a service to the platform as a service. Google also provides a strong commitment to security and stability.

With the help of the Google cloud platform, the user is free to think about the code and the feature which are needed to develop without worrying about the operations side.

Here most of the services fully manage and details quite easy for the customer to concentrate on their work. In this, machine learning and the use of API are very easy. The API also helps in speech detection language translation very easily. So it prefers among the customers.

3. IBM Cloud Services

IBM Cloud offers services such as platform as a service and infrastructure as a service. This cloud organization can deploy and access its resources such as storage networking and compute power with the help of the internet. Several tools help the customer to draw on deep industry expertise.

The speed and agility of the cloud fulfill the requirement of the customer and make them feel satisfied. A customer using the IBM cloud can easily find growth opportunities, generate new revenue schemes, and improve operational efficiency.

IBM cloud eliminates the complex problem and problems which face by large companies. IBM Cloud computing services are also helping home appliance manufacturers, retailers, and medical supply businesses. It uses it because it offers the best services with the price as low as possible.

Entering the cloud market later than other competitors, Oracle launched Oracle Cloud Infrastructure in 2016. Despite its late start, Oracle has played catch-up aggressively and has gained credibility as a cloud platform.

Oracle is not seen as a full-featured public cloud provider as are, say AWS and Azure. This, despite the company’s clear commitment to building out IaaS and PaaS offerings. Yet its focus is on offering its legacy strength in the database and other core enterprise offerings on a flexible, advanced cloud platform. In essence, it’s Oracle software on the Oracle cloud.

Still, the company is growing its market share significantly, and its cloud platform generally garners positive reviews.

5. Alibaba

A strong player in Asia, Singapore-based Alibaba is the cloud leader in China, and also is succeeding with its sales pitch to clients across the globe. To put it in perspective, Alibaba claims about $6 billion a year in cloud revenue (in contrast to AWS’s $40 billion yearly). The company does not have a significant cloud market share in North America.

In 2020, Alibaba boldly announced that it will spend some $28 billion on its cloud infrastructure over the next three years, adding an array of server, networking, and operating system build-outs. This additional investment will bulk up what is already a robust platform of IaaS and PaaS, a container service, a private cloud offering that’s geared for enterprise customers, and a machine learning platform for AI.

In short, while Alibaba doesn’t have quite the full-featured offering to rival that of the US-based cloud leaders, it is the leader in China and could compete aggressively in many global markets in the years ahead.

Types of Cloud-Computing

There are three forms of cloud computing, each with its own set of controls, management, and flexibility.

  1. Infrastructure as a Service (IaaS)

It provides resources like servers, networks, storage over the internet.

IaaS allows you to have the most freedom and control over your IT resources. It’s very comparable to existing IT resources that many IT departments and developers are already familiar with.

2. Platform as a Service (PaaS)

It’s a business strategy in which a third-party vendor supplies hardware and software tools that the user can utilize directly. This allows you to be more productive because you won’t have to worry about resource procurement, capacity planning, software maintenance, patching, or any of the other undifferentiated heavy lifting that comes with running your app.

3. Software as a Service (Saas)

The third-party provider hosts applications which will be available to users. You don’t have to worry about how the service is maintained or how the underlying infrastructure is managed when you use a SaaS provider. All you have to do now is consider how you’ll use the software.

One of the service providers of cloud computing and as used by Pandalytic Technology is AWS (Amazon Web Services) which is 100% public including the pay-as-you-go model. AWS is an Amazon company that offers metered pay-as-you-go cloud computing platforms and APIs to consumers, businesses, and governments.
