What Is IaaS, PaaS, and SaaS? Examples and Definitions: A Cloud Report

And the great thing about it is that you don’t have to be an IT expert or software engineer to install and use the SaaS app on each computer. Many of these apps directly run on a web browser, which means you only need a computer, a browser, and an internet connection to access them. Runtime environment provides common facilities on top of the operating system for applications built on a particular programming language to run smoothly. IaaS is a set of compute, networking, and storage resources that have been virtualized by a vendor so that a user can access and configure them any way they want.

However, instead of providing software over the web, it gives necessary development tools, operating systems, and infrastructure to the developers to build apps and software that perform specific functions. Building all of this also requires a lot of resources and experts in each of the fields, adding to the overall project cost. Point-and-click app building ‐ an advanced PaaS solution isn’t just for developers. PaaS empowers business users without coding skills to deliver their own solutions.

Platform-as-a-Service (PaaS) Explained

Although PaaS solutions are reliable, you’re still trading control for speed and convenience. There are some drawbacks you should expect when using PaaS to launch your application. The infrastructure you get includes virtualization, servers, network, and storage.

For example, you work with Python language, which is compatible with your current PaaS solution. Suddenly, the provider launches an update that requires JAVA for further compatibility. Here, you have to either change your programming language or the PaaS provider, consuming a lot of time and money. SaaS tools may not integrate with the apps and services that you already use. Popular SaaS offering types include customer relationship management, email and collaboration tools, sales automation, financial management, and more.

PaaS explained

SaaS vs. PaaS, what’s the difference and why should I care about one over the other. The pros for using Platform-as-a-Service are that it’s generally assumed that it’s quite fast and easy to get an app up and running, which is great. Let’s jump up to the top with Software-as-a-Service—that’s the easy one. Software-as-a-Service is just software that you don’t have to install on your machine and you don’t have to manually update.

Difference between IAAS, PAAS and SAAS

Some large enterprises that are not traditionally thought of as software vendors have started building SaaS as an additional source of revenue in order to gain a competitive advantage. Each as-a-service model offers a unique set of benefits befitting your specific use case. Traditionally, organizations use a mix of these different models for different aspects of the business; for example, an organization may use the Salesforce platform and Google Docs . SaaS is a comfortable service model for applications that are highly interoperable – used by multiple users internally and externally – and for short-term projects.

Cloud providers can deliver PaaS services through public, private, and hybrid cloud types. Integration with other cloud computing components like web services and databases. Provides tools and other software to build applications and a user interface for organizations to work with.

It translates the data moving through your system so applications with different communication methods can understand each other. You can manage every stage of your application’s life cycle through PaaS, focusing your app management on one platform. Leading to a much more convenient and cost-effective solution than if you collect all of them on your own.

PaaS explained

IaaS can have some drawbacks if the provider chosen is inexperienced or lacks the current market knowledge. Mindsight is a technology consulting firm that provides thoughtfully-crafted and thoroughly-vetted perspectives to its Chicago area clients’ toughest technology challenges. The as-a-service label has been utilized in every facet of the technological sphere. In fact, there are some within the industry who advocate for an “everything-as-a-service” model, which is simply suggesting that anything can be commoditized – not the most radical statement ever. When the decisions that led you to choose a specific vendor are no longer relevant, migrating to another vendor might be the logical choice. However they manage your infrastructure, the point is you don’t need to actively get involved.

SaaS Characteristics

Many IaaS providers now offer databases, messaging queues, and other services above the virtualization layer as well. Some tech analysts draw a distinction here and use the IaaS+ moniker for these other options. What users gain with IaaS is infrastructure on top of which they can install any required platform. Cloud platform services, or Platform as a Service , are used for applications, and other development, while providing cloud components to software.

PaaS explained

This frees up plenty of time for technical staff to spend on more pressing matters and issues within the organization. Parallels RAS also extends and streamlines the capabilities of Azure Virtual Desktop—Microsoft’s desktop as a service offering. Enterprises can integrate Parallels RAS deployment with existing or new Azure Virtual Desktops to deliver an all-in-one VDI solution to end users. Scaling the application development infrastructure in an on-premises setup can be wasteful and expensive.

Testing across cloud

Not every vendor follows standard APIs, protocols, and tools, yet the features could be necessary for certain business tasks. Because of the shared software development environment, DevOps teams can access all the tools they need from any location. Developers can access fully-configured environments that automate the application development lifecycle, including integration, pros and cons of paas deployment, testing, and security. However, SaaS companies deliver their software or apps to the end-user, whereas PaaS gives you a platform to build customizable apps. Furthermore, the SaaS provider takes care of all potential technical issues and manages the client’s data, storage, and application updates, resulting in streamlined support and maintenance.

In the end, serverless offers an infrastructure-free experience, where you don’t have to think about your infrastructure at all. Meanwhile, PaaS automates the management of your infrastructure, but you still need to understand it and make some changes now and then. Thanks to its task-based model, serverless computing scales automatically. With Paas, you need to configure it beforehand to make it scale automatically and can’t scale as quickly. Although it seems like serverless computing is more cost-effective, that’s not always the case.

Without these savings, the development costs of creating apps that keep pace with the market is fast becoming prohibitive. App development is faster because your IT and developers are no longer responsible for the hardware and software used to build, maintain and protect your application development platform. PaaS is part of a family of cloud computing tools which includesSoftware as a Service , Infrastructure as a Service , and Everything as a Service . The cloud computing model allows organisations to outsource computing services so they can dedicate more energy to their core business. Red Hat OpenShift is an open-source container-based platform focused on the private PaaS market. OpenShift provides developers with an integrated development environment for building and deploying Docker-formatted containers, with the target deployment platform being Kubernetes.

Additional resources and training may be required for the workforce to learn how to effectively manage the infrastructure. Customers will be responsible for data security, backup, and business continuity. Due to inadequate control into the infrastructure however, monitoring and management of the resources may be difficult without adequate training and resources available inhouse. While the customer is in control of the apps, data, middleware, and the OS platform, security threats can still be sourced from the host or other virtual machines . Insider threat or system vulnerabilities may expose data communication between the host infrastructure and VMs to unauthorized entities. Businesses can leverage Parallels RAS on Azure IaaS to deploy and scale their VDI workloads on-demand, rendering faster provisions and streamlining IT management.

The move to PaaS

On the contrary, PaaS customers get complete control over the application, and other menial tasks such as load balancing, software updates, etc., are left to the providers. As we move up the cloud computing layers from IaaS to PaaS to SaaS, there is more abstraction and less complexity for the cloud service users. PaaS offers a good balance of application control and abstraction for developers. Platform-as-a-service products are provided as web-based services via an interface. PaaS helps developers and business users focus on build great apps with clicks & code without having to worry about infrastructure and operating systems. Development tools, servers and programming environments are readily accessible, via the cloud, without the complexity and expense of creating them in-house.

  • Enterprise PaaS provides line-of-business software developers a self-service portal for managing computing infrastructure from centralized IT operations and the platforms that are installed on top of the hardware.
  • In this regard, IT teams must ensure that applications and OSs are working perfectly to achieve the utmost security.
  • If you’re looking for a platform where you can develop your application through all of its development stages and still have some control over your development environment, PaaS is the right choice.
  • Furthermore, the SaaS provider takes care of all potential technical issues and manages the client’s data, storage, and application updates, resulting in streamlined support and maintenance.
  • However, with PaaS, you buy only the additional capacity and begin to use it immediately.
  • IaaS is a flexible and scalable solution that enterprises can use to create and shrink resources on an as-needed basis.

However, with PaaS, you buy only the additional capacity and begin to use it immediately. The major drawback of leveraging IaaS is that IT teams are still responsible for ensuring the security of the infrastructure. In this regard, IT teams must ensure that applications and OSs are working perfectly to achieve the utmost security.

Use cases for PaaS

This enhances productivity as cross platform apps can be easily developed. PaaS delivers some pre-coded application components that can help users to reduce the time and efforts of typing individual codes. Some examples of IaaS service providers are AWS, Microsoft Azure and Google Cloud. Your provider will also assure that your infrastructure is reliable and meets service-level agreements . The complications and complexities that come with storage management can be completely avoided with IaaS.


Cloud computing services provide the speed, flexibility, and scalability that allows organizations to develop, innovate, and support IT operations. Infrastructure as a service , platform as a service , and software as a service are the three primary cloud computing services. Developing and testing apps in a hosted environment may be the most common use for PaaS, but it’s certainly not the https://globalcloudteam.com/ only one. PaaS tools also allow businesses to analyze their data, access business process management platforms, add communication features to applications and maintain databases. Simply put, with IaaS you’ll buy, install, configure and manage your own software—including operating systems, middleware and applications and then the cloud provider will manage this infrastructure for you.

Vendor lock-in

For example, scaling options should be one of the requirements you consider when picking a PaaS solution for your app. Don’t rush and defer thinking about the growth of your application and the future of your company. As PaaS is accessed through the internet, developers can work on their projects from anywhere worldwide using just their web browsers. If you need something to quickly and conveniently develop your application, there is a lot to gain from using a PaaS solution.
