As of now, we have talked about cloud computing and its different models. Today, I will talk about another cloud computing model which is called PaaS. So let's try to know What is PaaS model, and what does PaaS stands for?
Let's answer your first question. PaaS stands for Platform as a Service. The name states itself, PaaS is a cloud computing model in which we use a platform as a service. Now, we will see the answer of our second question, which was actually the first question that is "What is PaaS model"?
What Is PaaS? What Does It Mean To Use A Platform As A Service?
As we know, PaaS stands for Platform as a Service. PaaS is a cloud computing model that provides clients with both the platform and infrastructure to develop cloud applications over the Internet.
PaaS services typically include IT infrastructure such as data centers, servers and networking, and management of app development tools such as middleware, operating systems, runtime, virtualization and databases.
Cloud users have the option to choose from three different types of cloud host models which are as follows:
- Private cloud: For a single user
- Public cloud: For general public
- Hybrid cloud: A mix of both private and public cloud
PaaS services providers offer their services on a monthly fee or pay-as-you-go basis, as we have already discussed.
How Does PaaS Model Work?
We have talked about what is PaaS model, now we will see its working.
PaaS model generally has three components:
- Cloud infrastructure: Which includes virtual machines, operating system software, storage, networking and firewalls.
- A software to develop, manage and install the applications
- Graphical user interface: Where development teams can perform all their tasks throughout the application lifecycle.
Since PaaS provides all standard development tools through an online interface, developers can log in from anywhere to collaborate on projects, test new applications, or roll out finished products. Applications are developed and designed in the PaaS with the help of middleware.
PaaS services providers manage most of your cloud computing services, such as servers, runtime and virtualization. As a PaaS customer, your company maintains applications and data management.
What Is PaaS?: A Look At Its Uses
From developing to launching and updating an application, PaaS helps its users throughout the application life cycle. We will talk about some of its uses here.
1. Application Development
PaaS's computing resources, infrastructure, and predefined workflows provide software development teams with tools that reduce the coding required for web applications.
2. Developing And Managing APIs
PaaS model is useful for the businesses that develop and manage APIs and offer micro services.
3. Database Management
PaaS services providers can be used to create and manage a company's database, so that it has automated provisioning and administration functions that make it easier for clients to use the database.
4. IoT Processes
Internet of Things refers to all the devices that are connected with internet. PaaS supports all the programming languages, features that are required for IoT processes.
What Is The Difference Between PaaS, IaaS & SaaS
SaaS, IaaS, and PaaS are the three basic cloud computing models, related to cloud services providers, which provide customers with access to their own cloud-hosted data centers.
1. What Is SaaS?
SaaS vendors offer a cloud service and handle all aspects of software and hardware management. In SaaS model, users don't have to monitor the security upgrade, support and maintenance. SaaS is useful for new businesses that want to get off the ground quickly with low costs.
2. What Is IaaS?
IaaS services providers host physical data centers and manage servers, storage, virtualization machines, firewalls and security. Unlike SaaS, end users of IaaS must control and operate their own hosted applications, development management tools, and database management tools.
When different businesses need data storage and backup, web hosting and high performing computing resources, IaaS is their first priority.
What Is PaaS?
PaaS services providers give their clients a platform to develop, deploy and control business applications without the complex IT infrastructure required. In short, PaaS providers manage every thing for their users except applications and services.
When the businesses need development framework or data analytics to do informed business decisions, they can use PaaS.
What Are The Advantages Of PaaS Model
Additional tools and features of the PaaS model have several advantages:
1. PaaS Speeds Up Development Process
A PaaS vendor automates database provisioning and back-end processing so development teams can optimize their coding time and develop their applications faster.
2. PaaS Services Can Be Accessed Remotely
As PaaS is a cloud computing model, so the development teams can access it from any where. This way, they can access development environment remotely.
3. PaaS Services Are Cost-effective
Companies can avoid paying the high costs associated with purchasing and maintaining physical data centers.
4. PaaS Services Improve Scalability
With PaaS, businesses can easily scale up or down their resources because they don't need to buy as much hardware. Also, they don't have to waste unnecessary hardware due to fluctuations in demand.
What Is PaaS?: Final Words
Platform as a Service (PaaS) is a cloud computing model that provides a platform for the development, installation and management of applications and services. PaaS eliminates the need for businesses to invest in and maintain expensive hardware and software infrastructure. This helps developers to focus only on the development and installation of their applications.
With its scalability, ease of use, and affordability, PaaS has become a popular choice for organizations looking to develop and launch new applications quickly and efficiently.
