Difference between IaaS and PaaS: What You Need to Know

The ability to pay on a recurring or per-use basis enables enterprises to eliminate the capital expenses they traditionally have for on-premises hardware and software. Effectively, PaaS shifts the responsibility for providing, managing and updating key tools from the internal IT team to the outside PaaS provider. Microsoft Azure App Services is designed by Microsoft for building, testing, deploying and managing applications and services through Microsoft-managed data centers. There are numerous underlying infrastructure like middleware, app software and app data at the provider’s data centre.

PaaS explained

When using both services, you depend on a third party to manage the infrastructure, database, and software. However, you have even less control over your development environment when using serverless. Do you have data that you need to share with others in complete privacy? With SYNQION you combine maximum security and privacy with ease-of-use. Just declare any folder in your file system to be a SYNQION Space and invite people you want to share your data with to become members of your SYNQION Team.

In this lightboarding video, I’ll explain the basics of Platform-as-a-Service (PaaS).

So, make sure you trust and like your cloud provider before you choose it. All that leaves for the developer to provide is their data and applications. So, let’s think about what that means in terms of cloud computing and what the vendor provides and what the developer, or “Jane”, provides. 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. Flexibility is paramount ‐ businesses need to be fleet of foot to compete – and using platform services allows for innovation, scalability and affordability for every size of enterprise. Provides the freedom to developers to focus on the application’s design while the platform takes care of the language and the database.

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.

SaaS products are best for companies looking for easy-to-use applications to streamline their business processes. And PaaS is suitable for companies who want to develop their customized applications on an existing platform. Since PaaS provides a platform with built-in software components, you don’t need to develop an app from the ground up. This cuts down on the time, cost, and amount of code you have to write. 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. SaaS companies deliver their products via the internet to the end-users.

What is included in PaaS?

The model also enables DevOps teams to insert cloud-based continuous integration tools that add updates without producing downtime. Furthermore, companies that follow the Waterfall model can deploy an update using the same console they employ for everyday management. These platforms offer compute and storage infrastructures, as well as text editing, version management, compiling and testing services that help developers create new software quickly and efficiently. A PaaS product can also enable development teams to collaborate and work together, regardless of their physical location. 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.

  • These hardware and software services are managed by the provider and delivered to the user according to an agreement.
  • Grammarly uses real-time data insights to power its high-growth business.
  • IaaS is a flexible and scalable solution that enterprises can use to create and shrink resources on an as-needed basis.
  • Another mark of a maturing PaaS industry is the rise of outside integrations and support.
  • As mentioned above, there cannot be a “one size fits all” approach, when it comes to PaaS.
  • Latency and performance issues might occur if you access the software from far-off distances.

As a result, the model is similar to serverless computing and function-as-a-service architectures — meaning the cloud service provider manages and runs the server, as well as controlling the distribution of resources. PaaS technology offers a company virtual infrastructure, such as data centers, servers, storage and network pros and cons of paas equipment, plus an intermediate layer of software, which includes tools for building apps. Of course, a user interface is also part of the package to provide usability. Instead of having to purchase hardware outright, users can purchase IaaS based on consumption, similar to electricity or other utility billing.

The car metaphor for IaaS, PaaS, and SaaS

Navigating deployment alone can be confusing, frustrating, and all around meltdown-inducing. 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. Your files, documents and pictures are important to you, that’s why you want to keep, share and synchronize them.

As a third party manages most of your resources, using PaaS takes away control over your development environment in exchange for convenience. For one, the performance and availability of your application depends on the resources used by your vendors. Using PaaS significantly cuts your coding time because you only need to focus on your application and data, and a third party manages your backend processes and IT infrastructure. All the tools you need are centered on one platform, making it easier to manage your application’s life cycle. PaaS vendors provide and maintain the operating system you work on, and your application will run on. Serverless computing is another computing model that is very similar to PaaS, mainly because both of them take care of the backend processes of a web application for developers.

IaaS can have some drawbacks if the provider chosen is inexperienced or lacks the current market knowledge. Let’s look at what this means when it comes to the benefits and drawbacks of a PaaS database. https://globalcloudteam.com/ It may take considerable time to stand up an IaaS database implementation. If you’re willing to put in the work, IaaS gives you all the power—and the maintenance burden—of a traditional database.

SaaS Limitations & Concerns

Since a one-size-fits-all solution does not exist, users may be limited to specific functionality, performance, and integrations as offered by the vendor. In contrast, on-premise solutions that come with several software development kits offer a high degree of customization options. Due to its web delivery model, SaaS eliminates the need to have IT staff download and install applications on each individual computer. With SaaS, vendors manage all potential technical issues, such as data, middleware, servers, and storage, resulting in streamlined maintenance and support for the business. A PaaS solution typically includes a software development environment, middleware, operating system, database management, and infrastructure needed to maintain its life cycle stages. Of course, before choosing a PaaS for your enterprise, you need to consider and analyze various significant factors.

Cloud computing sounds ethereal and impossibly complex, but at the end of the day, it is simply access to computers. Cloud services are shared resources that provide applications, tools, and data on demand to businesses and individuals, freeing them from the necessity of ownership. It acts like a utility, providing as much or as little power as your business needs – and billing you accordingly. Private PaaS enables an organization to better serve developers, improve the use of internal resources and reduce the costly cloud sprawl that many companies face. Furthermore, private PaaS enables developers to deploy and manage their company’s applications while also abiding by strict security, privacy and compliance requirements. Some small and medium-sized businesses have adopted public PaaS, but bigger organizations and enterprises have refused to embrace it due to its close ties to the public cloud.

PaaS explained

Programmers want to focus on code – not on building and maintaining infrastructure. Offered via a cloud service provider’s hosted infrastructure, PaaS users are traditionally able to access a software development platform via a web browser. Easy access to a suite of development tools means programmers can program – and businesses can quickly deploy new applications. You simply tap into the cloud service provider’s PaaS to begin provisioning resources and developing immediately.

Popular SaaS offering types include email and collaboration, customer relationship management, and healthcare-related applications. 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. With SaaS cloud applications, the programme that runs the app is hosted on servers owned by the vendors not on your own machine. The key advantage of SaaS is that it can be accessed anytime, anywhere. This is great for businesses looking for tools that fulfil modern workplace trends like remote working and flexible working. This is how employees want to work in the 21st century – investing in SaaS can help you attract the best talent.

How does Platform-as-a-Service (PaaS) work?

Cloud computing provides numerous benefits to customers, offering flexibility, reliability, and scaling capabilities that are difficult for most businesses to match with on-site alternatives. Because you’re sharing resources, you don’t have to purchase or maintain that infrastructure, and instead can leave it to the experts. Your provider maintains the hardware and handles security, removing the need for a 24/7 IT technician on your site.

PaaS explained

The specific software development tools often include but are not limited to a debugger, source code editor and a compiler. Private PaaS. A private PaaS option aims to deliver the agility of public PaaS while maintaining the security, compliance, benefits and potentially lower costs of the private data center. This model is usually delivered as an appliance or software within the user’s firewall, which is frequently maintained in the company’s on-premises data center. A private PaaS can be developed on any type of infrastructure and can work within the company’s specific private cloud. PaaS architectures keep their underlying infrastructure hidden from developers and other users.

These could include pretrained machine learning models companies can use as-is or personalize with APIs for integrating specific AI capabilities into an application. PaaS works well for small businesses and startup companies for two very basic reasons. First, it’s cost effective, allowing smaller organizations access to state-of-the-art resources without the big price tag.


IT administrators might be involved with PaaS management, taking responsibility for PaaS setup, configuration, security and monitoring from the user/customer perspective. The fact is, cloud computing is simply becoming computing, and cloud-native design in new architecture is increasingly becoming the norm. IaaS can oftentimes lead to security gaps while also restricting user-privacy and customisation.

This is primarily a result of the large number of regulations and compliance issues that fall on enterprise application development within the public cloud. Platform as a service is essentially a layer between infrastructure as a service and software as a service . While IaaS provides just the pay-as-you-go infrastructure for a company, PaaS steps it up by also providing a variety of tools needed to create applications. Meanwhile, SaaS is ready-to-use software that’s available via a third party over the internet. 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.

PaaS products and solutions are most popular among application developers, as they can focus on the development of the application while the rest of the stack is managed. A PaaS product can also facilitate collaboration between geographically distant team members, allowing them to access the same development environment from separate locations. As an example, the VMware Tanzu Application Platform is expected to provide a suite of highly integrated Kubernetes-based application deployment and infrastructure management tools. This should enable VMware’s cloud-native IT automation products to integrate with the Kubernetes container orchestration platform. It will offer a comprehensive workflow for developers to build apps quickly and test on Kubernetes. PaaS can provide application lifecycle management features, as well as specific features to fit a company’s product development methodologies.
