What Is Platform as a Service PaaS? Definition, Examples, Components, and Best Practices

Google generally provides a set of highly capable servers that can cope with growing volumes of queries. Developers, however, have raised concerns regarding Google App Engine’s services. Some of the prominent issues include lack of support in some language environments, inadequate development tools, and failure to plug-and-play some applications, besides many others. Today’s digital world is constantly bombarding organizations with newer technologies and data.

PaaS users, like developers, can deploy their applications on the PaaS provider’s infrastructure and platform. Modern businesses are driven by fast-paced and highly agile environments that can adapt to real-time scenarios and bring about change immediately. It allows organizations to build customized applications and solutions with the aid of advanced tools and software machinery. Fundamentally, PaaS adoption avoids the reinvention of the cartwheel and reuses existing processes.

MWaaS provides a suite of integrations needed to connect front-end client requests to back-end processing or storage functions, enabling organizations to connect complex and disparate applications using APIs. MWaaS is similar in principle to iPaaS in that the focus is on connectivity and integrations. In some cases, MWaaS can include iPaaS capabilities as a subset of MWaaS functions, which can also involve B2B integration, mobile application integration and IoT integration.

Designing apps for millions of connected devices creates potential scalability and security challenges. 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.

Benefits of PaaS for Businesses and Developers

Security-conscious developers can identify and fix potential flaws in the application design by using threat modeling practices and tools. The Open Web Application Security Project has information on threat modeling and Microsoft offers a free threat modeling tool and information. This is because the provider controls the underlying infrastructure, which often impacts what can be done. This can lead to problems if there are changes or disruptions in the service.

Therefore, one needs to proceed cautiously and reach out for help whenever needed. Ultimately, Platform as a Service eliminates the expense and complexity of evaluating, buying, configuring, and managing all the hardware and software needed for custom-built applications. Multi-language development ‐ Multi-language support means developers can use and build on their existing skills, with apps written in the language that best suits their delivery and business goals.

The service is usually leased with pricing per month, varying according to the number of included devices and supported features. 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.

Development environments automatically provision, so teams can focus on work that adds value rather than on routine infrastructure management. IBM Cloud Pak for Applicationshelps you modernize existing applications, embed additional security, and develop new apps that unleash digital initiatives. It offers cloud-native development solutions that can quickly deliver value, along with flexible licensing that can be tailored to your specific needs. PaaS, or Platform-as-a-Service, provides a complete, flexible and cost-effective cloud platform for developing, running and managing applications.


This calls for knowledge, skill, and probably, some experience on a few cloud migrations. Hence, being an experienced CIO, seasoned IT professional, or software developer alone won’t serve the purpose. Results of the implemented pilot will allow businesses to forecast and predict the total cost. Otherwise, parameters such as incorrect autoscaling, failure in accurate forecasts leading to buying on-demand capacity, and automatic turning on certain services can lead to higher expenditure. Hence, working out the exact picture related to the cost and how to operate the PaaS platform is important.

  • PaaS architectures keep their underlying infrastructure hidden from developers and other users.
  • By leveraging PaaS, organisations can redirect a significant portion of their budgets from “keeping the lights on” to creating applications that provide real business value."
  • Cloud based services benefit from highly skilled teams who focus exclusively on security.
  • Furthermore, private PaaS enables developers to deploy and manage their company's applications while also abiding by strict security, privacy and compliance requirements.
  • It takes care of application integration, scalability, and load balancing.
  • These solutions are also commonly seen at businesses within virtually every industry.

Vendor lock-in is another common concern because users cannot easily migrate many of the services and data from one PaaS platform to another competing PaaS platform. Users must evaluate the business risks of service downtime and vendor lock-in when they select a PaaS provider. Both models provide access to services often based in a cloud, so it's worth drawing the distinction between platforms and software. SaaSis application software you use via the cloud, as if it were installed on your computer .

What is Platform as a Service (PaaS)?

Until the advent of PaaS, IT often had to manage individually licensed products. This meant having an individual process for any number of actions, including product evaluation, purchasing, integration, deployment, patching, upgrading, and so on. Frequently these products were sourced from multiple vendors, each with a unique approach to licensing, logistics, and security, making management increasingly complex and often resulting in gaps that created risk.

MPaaS solutions typically come with a wide range of features and services, such as push notifications, user management, and analytics. However, it can be more expensive than other types of PaaS, and it can be more difficult to find a provider that offers the features and services you need. With Red Hat paas saas iaas difference OpenShift, you can automate life-cycle management for increased security, tailored operational solutions, and app portability. You can also standardize developer workflows, streamline delivery, support multiple environments, and enable continuous integration alongside automated release management.

More about cloud computing

Examples of platform-as-a-service are AWS Lambda, Microsoft Azure PaaS, Google App Engine, Apache Stratos, and, which is a development platform for Salesforce customers. There are database-specific PaaS providers, for instance, as well as an emerging type called high productivity application PaaS , which features a graphical, low-code approach to development. There are three main cloud computing service models, namely SaaS (software-as-a-service), PaaS (platform-as-a-service), and IaaS (infrastructure-as-a-service). When an organization purchases PaaS from a cloud provider, they also get IaaS by default. For cloud-native development use cases, a Kubernetes-based PaaS can function as the platform on which container-based applications can run, scale, and be managed. For example, the cloud services editions of Red Hat® OpenShift® are managed PaaS offerings.

Other business leaders, such as legal compliance officers, can also be involved in PaaS decisions to ensure that PaaS use adheres to business continuance and regulatory requirements of the organization. The CIO/CTO can drive a PaaS initiative, directing staff to examine and evaluate PaaS as a supplement or alternative to locally managed tool sets.

Datto continuity for Microsoft Azure is an enterprise-grade business continuity solution that helps protect and recover Microsoft Azure workloads. It offers hourly replication to the secure and private Datto cloud that minimises single-cloud risk and ensures instant recovery during downtime, cyber attacks and outages. Middleware as a Service is something businesses use to help deploy middleware in a cloud environment. Messaging, queuing, and caching are some of the most commonly seen features. Integration Platform as a Service enables organizations to quickly and easily integrate their applications with other applications and data sources.

At the core, however, a platform ecosystem can be a central tool that supports transformation in meaningful ways. For your security, if you're on a public computer and have finished using your Red Hat services, please be sure to log out. Your Red Hat account gives you access to your member profile, preferences, and other services depending on your customer status.

All these are virtualized using a hypervisor, and managed by the cloud provider. Platform-as-a-service is a complete, scalable development and deployment environment that is sold as a subscription service. An organization can develop and deploy custom cloud applications without needing to invest in hardware or development tools. Likewise, an organization can use PaaS to extend or re-architect their existing applications in the cloud.

PaaS examples: Products and vendors

The main difference between them is that PaaS enables organizations to develop and deploy applications quickly and easily. IaaS enables organizations to provision and manage infrastructure in the cloud. SaaS enables organizations to use software applications in the cloud. In either case, the provider handles tasks such as capacity planning, patching, and system administration. This allows developers to focus on building applications and services.

Typically IaaS customers can choose betweenvirtual machines hosted on shared physical hardware or bare metal servers on dedicated physical hardware. Customers can provision, configure and operate the servers and infrastructure resources via a graphical dashboard, or programmatically throughapplication programming interfaces . Organizations need to be aware of the PaaS provider’s security measures to ensure that the systems and data are not vulnerable to an attack, even for a few minutes. Additionally, security during cloud migration should also be considered.

In terms of disadvantages, however, service availability or resilience can be a concern with PaaS. If a provider experiences a service outage or other infrastructure disruption, this can adversely affect customers and result in costly lapses of productivity. However, PaaS providers will normally offer and support relatively high uptimes -- though availability is governed by the provider's service-level agreement . Many cloud, software and hardware vendors offer PaaS solutions for building specific types of applications, or applications that interacting with specific types of hardware, software or devices. Because PaaS delivers all standard development tools through the GUI online interface, developers can log in from anywhere to collaborate on projects, test new applications, or roll out completed products.
