PaaS

PaaS (Platform-as-a-Service) is a cloud computing model that delivers hardware, software, and infrastructure tools to the customers through the internet. Usually, providers host development and deployment resources at their data centers which lets companies be more flexible and support web application lifecycle faster and cheaper.

In the article, we identify PaaS advantages and types, and compare it with SaaS. We also provide examples of PaaS and describe their features.

According to Statista, the PaaS market will be worth about 136 billion dollars in 2023, and worldwide spending on PaaS services is growing from year to year. Discover why this model is so popular and find out its benefits below.

• It makes application development and maintenance easier. PaaS hosts hardware and software tools on the remote servers and offloads most management on the provider. It lets companies reduce the number of administrative tasks and serve the platform easier. Also, some PaaS include pre-coded components, which let companies make their apps suitable for multiple platforms in a few clicks.
• It allows remote teams to work together. PaaS provides a shared software environment which makes the development process more flexible. Your employees can access the tools from anywhere they have an internet connection, which lets teams work on the same projects worldwide.
• It provides access to various resources. Typically, PaaS services offer many cloud-based tools, such as operating systems, development tools, databases, etc. You can use them right from the shared software environment, having only an internet connection and subscription to the service. It lets companies save money on the tools in the stack, which may be too expensive to install and manage independently.
• It lets you enter the market faster. Using PaaS helps you save time on purchasing and integrating hardware and software. You need to connect to the cloud-based service to start working on the development. Moreover, pre-coded components simplify your employees’ work a lot so that they can create applications much quicker.
• It is easy to scale. You won’t need to purchase additional hardware and software if more capacity is required. PaaS offers a more scalable approach. You can buy extra capacity right from the service, enlarge infrastructural resources and start using them immediately.
• It helps reduce equipment expenses. PaaS lets you try sophisticated tools without overspending on their purchasing outright. Also, it allows you to reduce costs on building and scaling application platforms, licensing costs, and management ones. A pay-as-you-go model helps you avoid expenses on unnecessary tools and services.
• It lets you avoid risks. You do not need to purchase software specifically to adopt new features. PaaS allows you to test various technologies without huge investments, such as operating systems, languages, databases, and other tools. You can get a vast application stack taking minimal responsibility and opt-out of some features anytime if it is necessary.

These benefits motivate many companies to start using PaaS in their app development. However, it may be difficult to differentiate it from SaaS, as they are rather similar. We compare these models and describe each one’s peculiarities in the next section.

According to BusinessWire, the SaaS market grows by approximately 9% every year. At the same time, PaaS is growing at 21.8% a year, Gartner states. Discover the difference between these two models and why more and more companies start using them.

PaaS (Platform-as-a-Service) offers a cloud-based application stack necessary for performing complex tasks, such as app development and management. Companies don’t need to buy and install any underlying infrastructure because providers host all the components on their servers. However, it is a brand’s responsibility to manage the app’s workload, as PaaS just offers tools to simplify this process. Also, businesses can retain control over the application’s features and associated information which lets consumers be more confident in data security.

SaaS (Software-as-a-Service) is a cloud-based software that you can access and use through the internet. It offers a complete application stack based on the remote servers so that you don’t need to purchase and install your infrastructure. Its main difference from PaaS is that SaaS providers manage workload and underlying IT resources, so companies cannot regulate app features, data storage, and information security. It lets companies save time and resources, but at the same time, they lose control over the critical part of the workflow.

Now you understand the difference between these two cloud computing models. Let’s further discover the types of PaaS you can use in your app development.

It may be difficult for some companies to figure out the peculiarities of different PaaS and choose the most suitable one for their app development. We review the most widespread Platform-as-a-Service types and describe their characteristics below.

• Public PaaS lets companies control software development and reach all other necessary components, such as storage systems, databases, frameworks, etc., through the public cloud. In such a case, providers host all middleware so that you don’t need to purchase and install infrastructure for app development. This type of PaaS may be a good decision for some simple apps, but some companies refuse to use it to avoid the public cloud and ensure greater data security.
• Private PaaS arranges application components into software that you install within the firewall and maintain in your company’s on-premises data center. It can be fully customized to your business requirements and work in a private cloud to provide complete data security. This type of PaaS helps companies be more flexible, reduce cloud sprawl, use internal resources more effectively, and comply with privacy requirements.
• Hybrid PaaS is a combination of private and public ones. It uses a hybrid cloud to provide a mix of different deployment types. This PaaS offers an infinite capacity as the public one and, at the same time, lets you control an internal infrastructure as the private one.
• Communication PaaS (CPaaS) allows developers to add features for users to voice, video, and messages in real-time. You do not need to build an infrastructure for your application and write code to let consumers communicate inside your app. This PaaS already includes programming interfaces and advancement packs.
• Mobile PaaS (MPaaS) offers an integrated environment to simplify mobile app development. It helps improve local applications, such as GPS, calendar, contacts, etc. without coding. MPaaS lets you access them directly through the gadget. You can use this computing model from the public, private or hybrid cloud.
• Open PaaS provides software that doesn’t include hosting. To develop and run your apps, you can use any programming language, operating system, and server. This PaaS lets consumers deploy their applications quickly and run them in an open-source environment.
• PaaS for Artificial Intelligence (AIPaaS) allows you to build applications that include artificial intelligence without purchasing hardware and software directly. It has pre-trained machine learning models that you can customize according to your app’s features. You can also integrate different AI capabilities to empower your application with such complex capabilities as speech-to-text conversion.
• Integration PaaS (iPaaS) lets you connect various applications on the cloud without purchasing additional infrastructure. You can integrate data and workloads across different environments to make your apps work together.

Understanding the main types of PaaS allows you to choose the best one you need to streamline development processes in your company. Continue reading to find out the best Platforms-as-a-Service and discover their features.
