PaaS, or platform as a service, is a cloud computing model that helps organizations operate efficiently. It makes use of third parties to offer hardware and software tools to users all over the internet for application development. The developers rent everything they need to build an application, install in-house hardware and software to develop new applications, and rely on a cloud provider for development tools, infrastructure, and operating systems.
Platform as a service enables the customers to develop, run, and manage the application without much effort and time. It further assists with building and maintaining the cloud infrastructure required to develop it. Simply put, platform as a service (PaaS) helps simplify web application development. In addition, it provides organizations with efficient application development so they can focus on the application itself.
Though different vendors offer different services, some of the core PaaS services are listed below:
- Development tools
- Middleware
- Operating systems
- Database management
- Infrastructure
- Application design
- Testing
- Deployment
Working of platform as a service (PaaS)
Platform as a service is a cloud computing software offered through a service provider’s hosted cloud infrastructure. PaaS can be made accessible through private, hybrid or public clouds. When using a public cloud PaaS, the customer manages the software deployment process while the cloud provider offers all the essential IT infrastructure required to host applications. Servers, storage units, networks, operating systems, and databases are a few examples of these components. PaaS is often provided as software or an appliance in a customer’s on-premises data center, behind the customer’s firewall, with a private cloud offering. Hybrid cloud PaaS offers a combination of the two types of cloud services.
PaaS offers essential services like application hosting or Java development instead of replacing the whole IT infrastructure of an organization for software development. It may also involve database integration, information security, and collaboration among development teams. PaaS comprises several underpinning elements of cloud architecture, such as servers, networking gear, operating systems, storage services, middleware, and databases.
The service providers are responsible for owning, running, configuring, and maintaining these technological solutions. Hence, customers can avoid spending money on these essential IT building blocks that they might not utilize to their best potential. PaaS also comprises frequently used resources, including database management systems, libraries, containers, programming languages, and other tools.
Benefits of platform as a service
PaaS hardware and software offer numerous benefits, such as streamlining development tools, reducing the cost of infrastructure, working on multiple operating systems and much more. Here is a list of the benefits of using PaaS:
- Faster time to market
PaaS allows developers to create applications more quickly than they could if they had to worry about creating, configuring, and supplying their platforms and backend infrastructure. Instead, they only need to write the code and evaluate the application using PaaS. The vendor is accountable for the rest.
- One environment from start to end
PaaS enables programmers to create, test, debug, host, deploy, and update applications all within the same environment. This facilitates the application development lifecycle and allows developers to verify that a web application will work as intended before it is released.
- Price
In many instances, using PaaS is more economical than using any other solution. For example, because PaaS users do not have to manage and provision virtual machines, overhead expenses are decreased. Additionally, some service providers offer a pay-as-you-go pricing model, where the vendor raises bills only for the application’s computing resources. This typically results in cost savings for the client. However, the pricing plans of each vendor vary, and some platform providers impose a flat monthly fee.
- Licensing ease
PaaS providers manage all licensing for operating systems, development tools, and other platform components.
- Easy and cost-effective solution
Scaling on an on-premises platform is always costly and occasionally insufficient. You must purchase more computing, storage, and networking capacity before high-traffic periods because they need to be expanded quickly enough to oversee sudden increases in demand. You can acquire more PaaS capacity and use it immediately.
- Flexibility for development team
With the support of PaaS services, development and operations teams can gain access to all the tools they would require with a stable internet connection. PaaS services provide a common software development ecosystem.
Use cases for PaaS
PaaS can facilitate or advance several IT projects by offering an integrated and ready-to-use platform. It allows businesses to delegate infrastructure administration to the cloud provider and concentrate on developing, deploying, and managing applications. These initiatives include –
- API development and management
- Internet of things (IoT)
- Agile development and dev-ops
- Cloud migration
- Hybrid cloud strategy
