Cloud computing Definition:

At its simplest, cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale.

A cloud computing service has three distinct characteristics that define its category:

It is sold on demand, typically by the minute or the hour.
It is elastic—it can scale up or down, as needed. The user only pays for what they use.
It is provided using a pay-as-you-go model.

Types:

There are three main types of cloud computing:

Infrastructure as a Service (IaaS)

Infrastructure as a Service, or IaaS, is one of the three most common models of cloud computing, along with Software as a Service (SaaS) and Platform as a Service (PaaS). In an IaaS model, a cloud provider delivers computer infrastructure – typically a platform virtualization environment – as a service, allowing businesses to access technology-enabled services without the need for on-premises hardware and software.

IaaS provides a way for businesses to access and use technology resources on an as-needed basis, without having to make the upfront investment in purchasing and maintaining those resources. This can help businesses save money, as they only pay for the resources they use. In addition, IaaS can help businesses be more agile, as they can quickly scale up or down their use of resources as their needs change.

There are a number of different types of IaaS, including public IaaS, private IaaS, and hybrid IaaS. Public IaaS providers make their infrastructure available to anyone who wants to use it, while private IaaS providers make their infrastructure available only to their own customers. Hybrid IaaS providers offer a mix of public and private IaaS, allowing customers to choose which type of infrastructure they want to use.

IaaS providers typically offer a pay-as-you-go pricing model, which can help businesses save money by only paying for the resources they use. In addition, IaaS providers often offer additional services, such as storage, networking, and security, which can help businesses further reduce their IT costs.

If you’re considering moving to a cloud computing model, IaaS is a great option to consider. IaaS can help you save money and be more agile, while still providing you with the ability to use the latest and greatest technology resources.

Platform as a Service (PaaS)

Platform as a Service (PaaS) is a cloud computing model in which a third-party provider delivers hardware and software tools — usually those needed for application development — to users over the Internet. PaaS is one of three main categories of cloud computing services, alongside Infrastructure as a Service (IaaS) and Software as a Service (SaaS).

PaaS offerings include a wide variety of development tools, application servers, database servers and other software that users can access and use to develop, test and deploy their own applications. Providers of PaaS services typically take care of managing and maintaining the underlying infrastructure and software, which frees users from having to do so themselves.

PaaS can be a good option for organizations that want to develop and deploy custom applications without having to invest in the underlying infrastructure and software. It can also be a cost-effective way to scale application development and deployment since users only pay for the resources they use.

Some of the popular PaaS providers include Amazon Web Services (AWS), Google App Engine, Heroku, Microsoft Azure and Salesforce.

Software as a Service (SaaS)

SaaS is a software as a service delivery model. It is software offered by the provider on the web. Customers can access and use the software, typically through a web browser, while the provider manages the infrastructure and security.

SaaS is one of three main categories of cloud computing, alongside infrastructure as a service (IaaS) and platform as a service (PaaS).

SaaS applications are usually designed to be easy to use and are often delivered with a user-friendly interface, such as a web-based portal. They are typically subscription-based, with customers paying a monthly or annual fee.

SaaS providers typically host the software on their own servers and manage all the associated infrastructure, including security, backups, and scalability. This allows businesses to offload the burden of these tasks to the provider, freeing up their own resources to focus on other aspects of their business.

SaaS applications are typically delivered over the internet, using a web browser, and can be accessed from anywhere in the world. This makes them highly convenient and flexible, as users can access the software from any location with an internet connection.

What are the benefits of SaaS?

There are many benefits of using SaaS applications, which is why this delivery model has become so popular in recent years.

Cost-effective: One of the biggest benefits of SaaS is that it is a highly cost-effective solution for businesses. There is no need to make a large upfront investment in hardware or software, as the provider takes care of all of this. Instead, businesses simply pay a monthly or annual subscription fee.
Scalable: SaaS applications are also highly scalable, which means they can be easily expanded or reduced to meet the changing needs of a business. This is a major advantage over traditional on-premise software, which can be difficult and costly to scale.
Flexible: Another big benefit of SaaS is that it is very flexible. Users can access the software from anywhere in the world and from any device with an internet connection. This makes it ideal for businesses with employees who work remotely or travel frequently.
Easy to use: SaaS applications are designed to be easy to use, with a user-friendly interface that requires little to no training. This makes them ideal for businesses with limited IT resources.
Increased productivity: Because SaaS applications are so easy to use, they can help to increase productivity by freeing up employees’ time. This is because employees can spend less time on training and more time on using the software to get their work done.
Security: Security is a major concern for businesses of all sizes. SaaS providers take care of all the security issues, including backups, updates, and patches. This takes the burden off businesses, allowing them to focus on their core tasks.
Reliable: SaaS applications are highly reliable, as they are backed by the provider. This means that businesses can be confident that the software will always be available and up-to-date.
Environmental friendly: SaaS applications are also more environmentally friendly than traditional on-premise software. This is because there is no need for businesses to use their resources to power and cool the servers that host the software.

What are the disadvantages of SaaS?

There are also some potential disadvantages of using SaaS applications that businesses should be aware of.

Dependence on internet connection: One of the biggest disadvantages of SaaS is that it requires a constant internet connection. This can be a problem for businesses with poor internet connectivity or for employees who work offline.
Limited customization: Another potential disadvantage of SaaS is that it can be difficult to customize the software to meet the specific needs of a business. This is because the provider controls the software and its features.
Security risks: There are also some security risks associated with using SaaS applications. Because the software is hosted in the cloud, businesses are reliant on the security of the provider. This means that there is a risk of data breaches and other security issues.
Vendor lock-in: Another potential disadvantage of SaaS is vendor lock-in. This is because businesses can become reliant on the provider for the software and its associated services. This can make it difficult and costly to switch to a different provider if the business is unhappy with the service.
Limited control: Another potential disadvantage of SaaS is that businesses have limited control over the software. This is because the provider controls the software and its features. This can be a problem if the business needs to make changes to the software or wants to add new features.

Which type is right for your business?

The type of cloud computing that’s right for your business will depend on your specific needs and requirements. IaaS is a good option for businesses that want the flexibility to scale their IT infrastructure up or down as needed. PaaS is a good option for businesses that want to focus on their app development, without worrying about the underlying infrastructure. And SaaS is a good option for businesses that want to access and use cloud-based software applications.
