Cloud computing

Cloud computing has revolutionized the world of IT and there are a variety of services that are available as a result. Computing services have been broken down into five categories, which is formally known as NIST model. In this article, we will compare and contrast SaaS, PaaS, IaaS, and FaaS, So that you can choose the right solution for your needs.

Cloud computing has revolutionized the world of IT and there are a variety of services that are available as a result.

Cloud computing services can be grouped into five categories: SaaS, PaaS, IaaS (Infrastructure-as-a-Service), FaaS (Functional as a Service) and DaaS (Deployment as a Service).

Computing services have been broken down into five categories, which is formally known as NIST model.

The NIST model is a standard for cloud services. It consists of five categories: SaaS, PaaS, IaaS, FaaS and DAAS (or “Data as a Service”). Each category contains sub-categories that differentiate them further.

For example: SaaS refers to software as a service; PaaS refers to platform as a service; IaaS refers to infrastructure as a service and so on.

We will compare and contrast SaaS, PaaS, IaaS, and FaaS so that you can choose the right solution for your needs.

SaaS, PaaS, IaaS and FaaS are the four cloud computing models that can be used to build a software-as-a-service (SaaS) application or a platform-as-a service (PaaS) application. Each model has its own advantages and disadvantages but in general all the four types of solutions share some common features like:

  • Flexibility – You can create new features easily within minutes compared to days or weeks if you start from scratch using traditional approaches.
  • Scalability – The number of users will grow over time without any additional effort because all your code runs on different virtual machines managed by an infrastructure provider like Amazon Web Services (AWS), Microsoft Azure etc..
  • Cost savings – As compared to starting from scratch with building your own infrastructure or hiring contractors who may charge high rates per hour they spend working on it during development stages themselves which would increase costs significantly over time due to inflation factor among other things involved in running these operations like maintaining servers etc…

Software as a service (SaaS)

Software as a service (SaaS), is a cloud-based solution where subscribers gain access to application software via web browsers or API. The SaaS model involves the delivery of software and services over the Internet, typically by means of a web browser. Unlike traditional software licenses, which require installing and registering each new copy of an application, SaaS allows users to access their applications from any computer connected to the Internet.

The term “software as a service” (SaaS) was coined by David Jelinek in February 2002. He defines it as “a combination of hardware and software that can be accessed remotely over the internet.”

Platform as a service (PaaS)

Platform as a service (PaaS) is a cloud computing model where developers can develop, run and manage applications without worrying about building infrastructure.

In this article, we will discuss the advantages of each solution based on their features and how they compare to each other.

Infrastructure as a service (IaaS)

Infrastructure as a service (IaaS) includes all the components that are needed by an organization to develop, test and deploy its applications on the cloud platform.

Infrastructure as a service (IaaS) is a cloud computing model where the provider delivers all the necessary infrastructure to the users, including servers and storage. In this model, users can deploy their own applications on top of these resources without having to worry about managing them themselves.

IaaS provides virtual machines and storage on demand; it allows users to choose from different platforms based on their needs or preferences. For example, if you want your application to run on Linux but not Windows then you would need an operating system provider who will provide VMs with appropriate software preinstalled onto them so that they can run any type or version of the operating system without having any issues with compatibility issues or performance issues associated with using just one specific type/version per user account (which would mean having multiple copies).

Function as a service (FaaS)

Function as a service (FaaS) grows in popularity with serverless architecture.

Serverless architecture is a way to deploy applications without having to manage the infrastructure. It’s like running your code in a cloud, but with no servers or cloud-hosted resources.

FaaS (function as a service) is a subset of serverless architecture that allows you to run code without having to manage the underlying infrastructure—that means less cost and risk for customers who want their apps up and running faster than before.

Data as a service (DaaS)

Data as a service (DaaS) is an IT delivery model that allows users to access data through cloud-based APIs. It’s different from other cloud services because it doesn’t require you to buy or manage hardware or software. Instead, you simply use the API to get what you need without having any downtime or downtime costs.

Benefits of using DaaS include:

  • Improved business processes by providing better access to information across multiple applications and devices
  • Reduction in costs associated with running traditional data centers by eliminating operating expenses such as electricity bills, maintenance fees, personnel costs and more

Summary

SaaS, PaaS and IaaS are three different approaches to cloud services that offer varying levels of abstraction.

  • SaaS is a fully managed service that provides all the tools you need to build and run applications in your own private data center. This can include application development tools as well as database management systems, email servers and content delivery networks (CDNs).
  • PaaS allows developers to build, test and deploy applications without worrying about infrastructure. It also provides access to open source software such as Ruby on Rails or PHP frameworks so they can quickly build their own applications without having to write code from scratch.
  • IaaS offers the ability to develop, test and deploy applications on the cloud platform using APIs provided by either Amazon Web Services (AWS) or Microsoft Azure

End Thought

Cloud computing has changed the traditional model of managing IT infrastructure. SaaS, PaaS, IaaS and FaaS are all types of cloud services that offer varying levels of abstraction. SaaS is a web-based solution where you get access to applications via web browsers or API (application programming interface).

PaaS is a cloud-based model where developers can develop minimum viable product (MVP), run and manage applications without worrying about building infrastructure. IaaS includes all the components that are needed by an organization to develop, test and deploy its applications on the cloud platform while FaaS grows in popularity with serverless architecture. Data as a service (Daa Service) is an IT delivery model that allows users to access data through cloud-based APIs
