Before we take you to the ride of SaaS or PaaS or IaaS, you should understand which giant companies are using which platform. Find the example below for each cloud computing:

SaaS – Companies like Cisco WebEx, Google Apps, Hubspot, Dropbox, Mailchimp, ZenDesk, Salesforce using SaaS platforms. 

PaaS – Companies Magento Commerce Cloud, OpenShift, Windows Azure, AWS Elastic beanstalk, Force.com uses PaaS platform. 

IaaS – Google Compute Engine, Digital Ocean, Amazon Web Services (AWS), Magento 1 depends on IaaS. 

Best Option SaaS or PaaS or IaaS?

Generally, online computing is divided into three categories and we are going to elaborate on each one below. 

SaaS: Software as a Service

Software as a service (SaaS) that works as a software distributor models. One of the software gets installed on the SaaS service and then any of the users can take access to it by using the browsers. 

In this method, the end-users don’t require to download and install the software on their personal computer. Instead of that, the same file can be accessed by any users who are on the same network. 

Third-party companies who provide the software, contact the cloud computing companies such as Saas to host the application there. An end-user doesn’t have to think about the infrastructure and setup because these platforms depend on the internet mainly. 

Advantage Of SaaS:

  • Infrastructure is not required as it works on the browsers. 
  • Save IT team cost, and work smoothly. 
  • Anyone from the same credential is able to access the data. 
  • You can access the documents from any computer, as long as you have the credentials.

The disadvantage of SaaS:

  • End-users have no control over the server so if something goes wrong then the only thing you have to do is WAIT. 
  • Lack of data security because all comes from the servers and goes into the server.
  • Lack of performance because everything works on the browser so sometimes it may reflect a lack of performance.  

PaaS: Platform as a Service

PaaS is a platform that enables you to develop any kind of application, database management, middleware, or analytics. Using PaaS cloud computing enables you to build software on the cloud server. 

For this, you have not required a set of computers, servers, and heavy storage devices because everything happens online here. For developing big software such as operating systems, heavy databases you will be required a heavy system, but PaaS made it easy for the users. Your data will be stored on the internet. 

These kinds of cloud computing support multiple languages. You can give a hand to all these if you need to. The only problem with the PaaS system is, nothing will be in your hand, so if anything goes unexpectedly then you won’t be able to do anything. 

Advantage Of PaaS:

  • Users can build multiple different projects using PaaS, as it supports various languages. 
  • No need to keep a server or storage device locally, as all the datastore on the cloud server. 
  • Files and documents can be accessed by multiple users.
  • Budget-friendly, multiple device support (Mobile, Desktop)

Disadvantage of PaaS:

  • Users should be familiar with the coding skills to work on the PaaS. 
  • If you are stuck somewhere on technical stuff, you hardly get any customer support. 
  • Less control over the server, so for any server issues you can’t do anything. 
  • Multiple users on the shared server. 

IaaS: Infrastructure as a Service

IaaS works on the pay-as-you-use model so it can be useful for all types of business (Small, Medium, or Large) in these platforms you pay-as-you-go storage. So it opens the windows for the business to take the required space from the IaaS. 

Using the IaaS on the business enables you to access the computing infrastructure such as operating systems, servers, storage, network, through virtualization technology. 

As in the SaaS and PaaS, everything is managed by the providers but here in the IaaS client takes the responsibility to manage all the things such as applications, middleware, OSes, runtime, and data. 

But the hardware parts like hard drives, network infrastructures, storage, and virtualization are managed by the service providers. 

Advantage of IaaS:

  • IaaS enables pay-as-you-go storage for the users. 
  • Handy for all kinds of businesses. 
  • Highly scalable and more flexible. 
  • Resources can be purchased as the user’s requirements. 
  • Pay only for that, you used. 

The disadvantage of IaaS:

  • You still would need the technical team to manage all these pieces of stuff. 
  • Security at risk because all the data stores on the cloud-based server so security threats are always at risk.
  • Lack of flexibility over the data.
