Cloud Computing Explained: SaaS, PaaS, and IaaS

You can access a wide range of resources such as OSs, middleware, databases, and development tools that would otherwise be expensive to purchase and own in an on-premises setup. Consider IaaS to be the foundation of every cloud-based service, whether that’s content, software, or a shopping website. Platform as a service allows developers to build apps without having to host them themselves, whereas SaaS refers to software that you can buy or sell to help software companies get things done.

PaaS explained

Any PaaS offering necessarily includes the IaaS resources required to host it, even if those resources aren’t discretely broken out or referred to as IaaS.

Operating systems

You don’t have to keep reinventing the wheel each time you build a new app, which cuts your development costs. Capital costs – money tied up in costly and fast depreciating IT assets – are removed in favour of operational costs that are offset against business ROI. Once you have signed up to PaaS, you can start using the system straight away – no set-up time lag.

  • This eliminates the need for a business to purchase, deploy and maintain that application in-house, enabling the business to reduce its in-house IT footprint.
  • They make it easier for teams to manage their databases through cluster automation tools.
  • What developers gain with PaaS is a framework they can build upon to develop or customize applications.
  • If you lose your computer or it breaks down, you can restore your data easily.

Development tools, servers and programming environments are readily accessible, via the cloud, without the complexity and expense of creating them in-house. Apps can be developed and hosted faster and with very low setup costs, without the risk of delays or inefficiencies caused by infrastructure issues. Put simply, PaaS allows developers to concentrate on what they do best, so they can produce high-quality results, faster.

Building applications on PaaS vs. on-premises

On serverless, you’ll find a less complete toolset than the ones in PaaS. This way, developers can focus on their business and improving their application instead of fussing over the general technical efforts needed for pros and cons of paas back-end processes, such as setting up servers and maintaining a database. PaaS works in tandem with DevOps strategy to continuously deploy applications and increase automation, leading to a reduced time to market.

Many businesses believe that their current IT set up works well for them. However, as more and more businesses move to the cloud and take advantage of the benefits listed above, those that don’t risk falling behind their competitors. With our powerful recommendations and easy-to-use tool, it’s never been easier to reduce your cloud costs. When the data of an app is stored in the cloud, the data can be easily retrieved even if the user changes his device or if the device suffers any damage.

It’s highly likely that this will affect your business and become a big event for your business and customers. Investigating and testing your vendor’s security and compliance policy and any third party is a lot of work, but it’s necessary for your users’ safety. Security and compliance concerns are things you must handle if you’re using a cloud-based system. Some PaaS vendors use a pay-as-you-go system, making it easier to control your finances. Others offer a flat fee like any other subscription-based services, but it’s still limited by how many resources you’re planning to use.

Software updates, maintenance, security, and compliance—it’s all included in the subscription plan. Immensely improve development productivity and application delivery processes with minimal investment. Let’s see how various PaaS offerings differ through the prism of their use cases and supported technologies and how to determine which one will meet your specific needs. Another cost benefit of Platform-as-a-Service is that you don’t have to pay for a full-time system or IT admin to run this app, they can focus on something else. It’s easy to create and delete the resources, which is important for, say, you’re running a proof-of-concept app for a conference and you want to spin it up right before the conference and then delete it right after.

Larger companies may prefer to retain complete control over their applications and infrastructure, but they want to purchase only what they actually consume or need. Although it’s great that you have more time and resources to focus on your application and users, using PaaS means you depend on your vendors. However, most of your resources are managed by a third party, so moving your application might get messy without your vendor’s fair migration policy.

Development teams that choose to use CPaaS can save on infrastructure, human resources and time to market. PaaS is a cloud computing service that uses virtualization to offer an application-development platform to developers or organizations. This platform includes computing, memory, storage, database and other app development services. PaaS solutions can be used to develop software for internal use or offered for sale.

Examples of PaaS providers are SAP, Heroku, Microsoft Azure, VMWare, Google App Engine, and Swisscom. Swisscom has built its New Application Cloud PaaS for Microservices with MongoDB Enterprise Advanced. MongoDB is also the core content management component of SAP’s PaaS offering and VMWare’s PaaS. SaaS solutions are fully managed by the third-party vendor—from the application’s updates to the client’s data to storage. 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.

While customers can run legacy apps in the cloud, the infrastructure may not be designed to deliver specific controls to secure the legacy apps. Minor enhancement to legacy apps may be required before migrating them to the cloud, possibly leading to new security issues unless adequately tested for security and performance in the IaaS systems. Cloud infrastructure services, known as Infrastructure as a Service , are made of highly scalable and automated compute resources.

Without that connection, end users can’t access their data, their applications, or anything else that’s not also locally available. This isn’t necessarily a huge concern for every business, but it does require a little more care when planning out business operations. While the average person typically encounters SaaS more than PaaS or IaaS, it’s Infrastructure-as-a-Service that probably springs to mind when you think about cloud computing. IaaS is, as the name suggests, a way of providing infrastructure to users as an on-demand service.

You can choose the pay-as-you-go pricing model where you pay only for the resources consumed or pay a fixed fee for a specified amount of resources developers need. Even the definition of this cloud computing service model is quite vague today. Commonly, it is described as a cloud hosting platform with a set of deployment and scaling automation, application management, and DevOps tools that can be run on shared infrastructure or on-premise. Also, PaaS eliminates the complexity of building and maintaining the underlying infrastructure. PaaS helps developers and business users focus on build great apps with clicks & code without having to worry about infrastructure and operating systems.

Most SaaS applications can be run directly from a web browser without any downloads or installations required, although some require plugins. PaaS has been a life-saver for developers and programmers and is mostly used by them. With PaaS, users can develop, run and manage their apps without having their own infrastructure and platforms. And just like IaaS, PaaS also offers a convenient pay-as-you-go system. Platform-as-service or PaaS takes your cloud computing game a level higher. With more services available through the cloud, PaaS allows organisations to focus only on applications and data and better ways to grow their business.

PaaS explained

You can use PaaS’s inbuilt tools to analyze and mine organization data, discovering insights and patterns that can help the business improve forecasting, investment returns, and other decisions. Since the PaaS company stores your sensitive data, it can pose security risks and concerns to your app’s users. You can easily create large, complex applications without downloading the related infrastructure. Ensure that your PaaS provider allows you to import/export data easily without any lock-in. As the digital environment matures, a number of drivers are strengthening the rationale for adopting cloud computing.

Two Types of Cloud Computing Service Models

Mid abstraction level PaaS platforms have the main objective of letting the developers design the code without worrying about infrastructure configuration and management. Most commonly, such PaaS solutions offer load balancing, auto-scaling, backup, high-availability, CI/CD, disaster recovery, and other such product lifecycle management features right out of the box. Cloud-based technology gives users control, flexibility, and tools that on-premise software simply cannot provide. Whether you need cloud service for monitoring your business operations or a smooth platform to create customized applications—there is a cloud-based solution for everything. Platform as a Service or PaaS is a set of cloud based services that enable business users and developers to build applications at a speed that on-premise solutions cannot match. As it’s a cloud based service there’s no need to worry about the set-up and maintenance of servers, patching, upgrades, authentication, and so on, users can just focus on creating the best user experience possible.

It translates the data moving through your system so applications with different communication methods can understand each other. If you’re planning to build a web application, a PaaS solution should be something you’re considering, given the benefits it brings to the table. Some examples of PaaS providers are EngineYard, Heroku, Microsoft Azure, AWS Elastic Beanstalk, and Google App Engine. Some of the major PaaS players that work with MongoDB Atlas are AWS, Microsoft Azure, Heroku, and Google Cloud, amongst others.

A popular consumer app can easily overwhelm a data centre, and your brand can take a big hit if the end-user experience suffers. Services like Instagram and Twitter process millions of posts each minute. While business apps are less likely to boom to this extent, if your app does exceed expectations, a cloud-based solution means you’ll be able to take advantage of the situation. Upfront costs are reduced, since there’s no need to build anything before you begin developing. Using a platform like Salesforce also helps with the standardisation and consolidation of resources and app components.

What Is PaaS?

Most of us already use SaaS to some extent without even realising it. The apps that we use through the internet; like Microsoft office 365 is a form of SaaS. Out of the 3 main cloud services available, IaaS allows the most accessibility to businesses. With IaaS, you can hire a provider — with a pay-as-you-go convenience — to help you with infrastructure services like storage, network, servers and virtualisation through the internet.
