“If someone asks me what cloud computing is, I try not to get bogged down with definitions. I tell them that, simply put, cloud computing is a better way to run your business.”
—–Marc Benioff, CEO of Salesforce.com
Microsoft defines Cloud Computing as the delivery of computing services—servers, storage, databases, networking, software, analytics, intelligence and moreover the Internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale. You typically pay only for cloud services you use, helping lower your operating costs, run your infrastructure more efficiently and scale as your business needs change.
So we can just say that Cloud computing is the on-demand availability of computer system resources, especially data storage and computing power, without direct active management by the user.
Since we are all now clear with the basic definition of Cloud Computing, let’s get into details like “Why we need Cloud Computing?”, “How Cloud works?”, “Types of Cloud Computing” and finally “Top Cloud Computing Service Providers in 2019.”

Why We Need Cloud Computing?
We are seeing technology moving to the cloud more and more every day. It is not just a trend — the shift from traditional software models to the internet has steadily gained momentum over the last 10 years. Looking ahead, the next decade of cloud computing, it promises new ways to collaborate everywhere, through mobile devices.
So why this shift? What exactly does Cloud Computing offers? Why we need Cloud Computing?
Well, Traditional business applications have always been very complicated and too expensive. With the amount and variety of hardware and software required to run them are formidable. You need a whole team of experts to install, configure, test, run, secure, and update them. Here are the six common reasons organizations are turning to cloud computing services:
Cloud Computing’s main advantage is that it eliminates the capital expense of buying hardware and software and setting up and running an on-site datacenter. The services are free from capital expenditure. There are no huge costs of hardware in cloud computing. You just have to pay as you operate it and enjoy the model based on your subscription plan.
Most of the cloud computing services provide self-service and on demand, so even huge amounts of computing resources can be provisioned in minutes, typically with just a few mouse clicks, giving businesses a lot of flexibility and taking the pressure off of capacity planning thus, saving a lot of valuable time.
3. Global Scale:
Cloud computing offers yet another advantage of working from anywhere across the globe, as long as you have an internet connection. Even while using the critical cloud services that offer mobile apps, there is no limitation of the device being used.
Cloud Computing allows your department to be more flexible and collaborative and make available all the latest data so that quotes and forecasts are more accurate. One of the biggest contributors to productivity is the 35-40% increase in productivity that large companies like British Telecom, Best Buy and Dow Chemicals have experienced when allowing employees to work remotely which is possible only with the introduction of Cloud Computing.
Scalability can be defined as the ability of any system to accommodate larger loads just by adding resources either making hardware stronger (scale up) or adding additional nodes (scale out). Now, with the Internet of Things, it is essential that software functions across every device and integrates with other applications. Cloud applications can provide this.
Data loss is a major concern for all organizations, along with data security. Storing your data in the cloud guarantees that data is always available, even if your equipment like laptops or PCs, is damaged. Many cloud providers offer a broad set of policies, technologies and controls that strengthen your organization’s security posture overall, helping in protecting your data, apps and infrastructure from any potential threat.
Let’s get straight onto our next discussion – “How Cloud Works?”
How Cloud Works?
Cloud Computing is a kind of outsourcing of computer programs. Cloud storage works by enabling users access and to download data on any chosen device, such as a laptop, tablet or smartphone. Cloud storage users can also edit documents simultaneously with other users as well, making it easier to work away from the office.
To understand how exactly cloud computing works, it can broadly be divided into front-end and backend.
The front end will enable a user to access data that is stored in the cloud using an internet browser or a cloud computing software. However, the primary component of cloud computing – responsible for securely storing data and information – is the backend. It will comprise of servers, computers, databases, and central servers.
The central server will facilitate operations by following a set of rules known as protocols. It uses a software, middleware, to ensure connectivity between devices/computers linked via cloud computing. Cloud computing service providers usually maintain multiple copies of the data to mitigate instances of security threats, data loss, data breach, etc.
Types of Cloud Computing:
Generally, Cloud Computing services are classified into three types: infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS). These are sometimes called the cloud computing stack because they build on top of one another.
1. Infrastructure as a service (IaaS):
Infrastructure as a service (IaaS) is a form of cloud computing that provides virtualized computing resources over the internet. With IaaS, you rent IT infrastructure—servers and virtual machines (VMs), storage, networks, operating systems—from a cloud provider on a pay-as-you-go basis. It is the most basic category of cloud computing.
2. Platform as a service (PaaS):
The Platform as a service (PaaS) service delivery model allows a customer to rent virtualized servers and associated services used to run existing applications, or to design, develop, test, deploy and host applications.
3. Software as a Service (SaaS):
Software as a Service (SaaS) is a method for delivering software applications over the Internet, on demand and typically on a subscription basis. With SaaS, cloud providers host and manage the software application and underlying infrastructure and handle any maintenance, like software upgrades and security patching.
