SaaS and cloud computing are two related technologies that business leaders consider when evaluating technology options to build software to run their businesses.
Despite not precisely being a chicken-and-the-egg paradox, Software as a Service (SaaS) wouldn’t be possible without the cloud.
Even yet, SaaS and cloud computing are two phrases that people frequently conflate.
Overall, the term “Cloud Computing” is an umbrella term that refers to on-demand access to a variety of computing resources consisting of IaaS, PaaS, and SaaS which benefits businesses in terms of flexibility and cost saving.
SaaS Vs Cloud Computing
The delivery of scalable and elastic IT-enabled capabilities as a service through the internet is known as “cloud computing.”
Software that is owned, supplied, and managed remotely by one or more providers is known as software as a service (SaaS).
In a one-to-many approach, the provider delivers software that is consumed at any time by all of the contracted clients on a pay-per-use basis or as a subscription depending on use metrics. — Gartner Glossary
SaaS and cloud computing both provide similar advantages to users and are offered via the Internet.
They don’t exist on the user’s computer or a company server, therefore they don’t need tedious installations or ongoing maintenance.
On the “server side,” all software updates, installations, ongoing maintenance, etc. issues are handled.
SaaS and cloud computing are both available by subscription and are instantly accessible from any location where a user has an Internet connection.
SaaS Development and Cloud Computing: Here’s How they Relate?
SaaS is a subset of cloud computing. It’s crucial to remember that not all SaaS solutions are cloud-based.
Applications or SaaS products can be created locally and then deployed to a cloud-based server.
A web browser is used to access and use the actual product. Cloud software has three subcategories: IaaS, PaaS, and SaaS.
Products that are SaaS-based have two essential characteristics. The software is immediately served to you, hosted, pre-configured, and ready to use; this is the first characteristic.
This drastically decreases entry-level barriers to the market because there is nothing to install, buy, or worry about the hardware.
You do not own the software, which is the second characteristic.
With SaaS, you are paying for a service rather than buying the software altogether.
This usually applies to a subscription model, where you pay for the service on a monthly or annual basis.
Faster installation times and the hosting company would take care of any necessary upgrades in the future are two benefits of SaaS applications. Gmail, a mail service offered by Google, is a great example.
On the other hand, cloud computing provides solutions that can be utilized to create a unified approach to cloud-based data storage, as well as services similar to SaaS apps.
It can include PaaS products that developers can use to design, test, and deploy software as well as IaaS solutions or an IaaS model that permits the use of servers, data centers, and security resources to manage essential business activities.
These opportunities come together as one when a whole cloud computing solution is implemented rather than existing as separate elements.

People tend to use the terms SaaS vs Cloud services as interchangeable notions and this is wrong. The first thing you need to remember is that Cloud and SaaS are not equivalent.
SAAS means the software as a service.
The service is used for providing third-party host applications by using a software distribution model.
It ensures the features’ availability to the customers on the internet.
It has three classifications; cloud computing, infrastructure as a service (IAAS) and platform as a service (PAAS).
It is used for an application service provider (ASP) and software delivery models.
IaaS-based cloud web hosting platforms provide customers with complete control over their web hosting experience, with emphasis put on the operating system used and the resources of virtual machines.
eNlight from ESDS is a prime example of an IaaS implementation because our cloud hosting clients are able to develop their virtual machines with the resource that they wish to see, as opposed to choosing a pre-defined web hosting plan as outlined by other forms of web hosting.
IaaS implementations can provide businesses of all sizes with a variation of benefits such as:The pay per use configuration of this cloud platform basis ensures that customers are only billed for the resources that they are using, along with any additional features purchased to support their VMsScalability is offered through the option to order additional capacity for your virtual machines as demand increases; with eNlight you will also find that auto-scaling is supported providing vertical and horizontal scalingReliability and security are two features that IaaS can offer as additional control can be offered to clients, putting them in a position similar to what a dedicated server provides.Additional control of particular networking components is also a possibility because to some degree it is important for businesses to have control over factors external to their cloud virtual machines.
Popular options chosen by larger users of cloud web hosting can include:Setting up a virtual LAN between multiple virtual machines in the cloud can create a secure communications channel between these serversAccess to routers can be provided to offer load balancing in the cloud for websites that experience high volumes of trafficAPIs can be built into the software layer to offer advanced control of virtual machines from third-party interfaces, whether these are desktop applications or web applications.ESDS utilizes the concept of IaaS with our eNlight cloud hosting services, one of the most advanced cloud hosting platforms available today.
We also offer private cloud solutions for situations where a shared cloud doesn’t provide the desired level of control.Platform as a Service (PaaS)PaaS services related to applications or services that are hosted in a central location where the user doesn’t have control over the operating system layer or any of the hardware involved.
The best example of PaaS is where hosted Microsoft Exchange email Server is offered within the context of a shared platform where multiple users share the same Exchange server environment; here the consumer will have no control over the hardware, OS or application layers, but can create additional email accounts that can access and use the Exchange environment.
