The Key Differences Between On-Premise, SaaS, PaaS, IaaS

        SaaS, PaaS, and IaaS are three ways to describe how you can use the cloud for your business, each of these models offers a progressive level of abstraction – or management – by the cloud provider. 

as a service


=============================================================================


Platform as a Service (PaaS)

PaaS

    Platform as a Service (PaaS) delivers cloud components to software while being used for applications and other developments. What developers gain with PaaS is a framework they can build on to develop or customize applications. PaaS enables fast, simple and cost-effective development, testing and integration of applications. With this technology, enterprise operations or a third-party provider can manage operating systems, virtualization, servers, storage, networking and PaaS software themselves.
 
    PaaS is designed for developers to quickly build their web or mobile applications without the hassle of setting up and managing the underlying infrastructure of servers, storage, networks and databases required for development. Enterprise PaaS provides a self-service portal to enterprise domain software developers to manage computing infrastructure from centralized IT operations and platforms built on the infrastructure. 
 
    Just like the way you create macros in Excel, PaaS lets you build applications using software components built into PaaS (middleware). Applications using PaaS include cloud characteristics such as scalability, high availability, multi-tenancy, SaaS efficiency, and more. Businesses benefit from PaaS as it reduces the amount of coding required, automates business policy, and helps migrate applications to the hybrid model. 
 
Benefits of PaaS
 
Cost reduction : In the past, developed software was expensive as a result of the required hardware, skills and experience. Instead, PaaS effectively allows users to lease the necessary infrastructure, which it gives for a subscription fee. 
 
Eliminating the skill barrier : PaaS systems are generally easy to use, meaning businesses don't need to employ experts to develop their applications. Rather, an application can only be developed in-house via a web browser. 
 

Increased collaboration : In large businesses, multiple parties may be working on the same application development project. With cloud connectivity, multiple developers in different locations can collaborate on the same project. 


=============================================================================


IaaS – Infrastructure as a Service


    The primary function of Infrastructure as a Service is to provide visual data centers to businesses. This cloud service is suitable for IT administrators. IaaS offers a full infrastructure, the server, and the storage space where new technologies and experiments are conducted over the cloud. With IaaS, you can perform data mining analysis, host a website and software solution, and creating virtual data centers for large scale enterprises.

    In IaaS, the vendor works on networking resources, storage space management, and the dedicated data center. On the other hand, the business is working on specified tools for development, managing apps that are hosted, and deployment of the operating system.

IaaS


Advantages of IaaS

  • It is cost-effective

  • It can still operate even if the server goes down

  • It is flexible enough

  • The main focus of IaaS is how to grow and expand a business

  • There is no need for regular upgrade of software, hardware resources, or even troubleshoot equipment issues. It has on-demand scalability

Disadvantages of IaaS

  • IaaS is highly dependent on third-party or the provider for the data.

  • There is no cloud security control in IaaS

  • Sometimes organizations fail to access to data and applications due to technical issues

  • Some of the businesses software does not get upgraded

  • IaaS restricts customizations and users don’t have privacy

  • The IaaS service provider is sophisticated, hence requires only professionals


=============================================================================


SaaS- (Software as a Service)

SaaS

    

    SaaS offers the complete package of a web application program. A SaaS provider manages all system layers from hardware to applications, so that all a user needs to do is to sign on and use the application. Most SaaS programs allow direct access from a web browser. Software as a Service cloud service is hosted by the service provider, which is available to the consumers based on the pay-as-you-go. SaaS cloud service is suitable for consumers across different localities. The software license is open on either yearly or monthly subscriptions, and it can be accessed via a browser with stable connectivity of the internet.

Some of the business apps that use SaaS include the following:

  • Human resource software management

  • Mobile app development

  • Customer relations management

  • Communication and office software

  • Planning enterprise resource programs

  • Accounting and payroll programs

  • Corporate performance management suites


Benefits of SaaS
 
Elimination of start-up costs: SaaS is often provided on a subscription basis because it eliminates the initial costs traditionally associated with software implementation. SaaS allows breaking the initial cost barrier and enabling easier and more affordable access to sophisticated systems.
 
Payment stops on discontinuation : Another benefit of the SaaS system is that you have the possibility to terminate your contract when a subscription no longer requires the software. 
 
Secure data : By using cloud-connected software systems with SaaS, you eliminate the vulnerability of storing files on a local device. Plus, you always have a digital backup at hand. 
 
Flexibility : One of the main advantages of SaaS is the flexibility it offers. You can access the applications you need wherever you use a simple internet connection.
