Iaas, SAAS, Paas: Types of Cloud Computing Services - Part 2

Cloud computing didn't lose any users whether they are developers, simply customers, managers and created three types of cloud computing services SaaS, PaaS and IaaS.

SaaS  ( Software as a Service)

--For Customers

The product is maintained by the service provider.

You just have to use the software based on your subscription plans.    

  Why SaaS?

• Users don't have to understand the algorithm behind it use the software and solve your problems.

• Users don't have to buy expensive software, just pay for it if there is some subscription and stop paying if u don't want to use.

• The source code is not available to users so no stealing of data. 

                   Just consume!!!

SaaS examples

•Video watching platforms ( Netflix, Amazon Prime, Hotstar, YouTube)
•Messaging platforms ( Twitter, WhatsApp)
• Google Drive, Dropbox etc.

              

PaaS ( Platform as a Service)

--- For Developers

You have to focus & management of apps created.

Don't worry about the configuring hardware or OS.

Why PaaS?
• It prevents you from buying hardware or software for deploying your apps

• Companies spends more time on software development rather than management and maintenance.

•Deploying apps require a high degree of skill but PaaS reduces in simple steps.

                    Just Build !!!

PaaS examples

Google App engine,Heroku,Force.com etc.

IaaS (Infrastructure as a Service)

-- For Admins

The basic building block of cloud IT provides access to networking, OS, data storage. 

 Don't worry about the IT guys, servers and hardware.

Why IaaS?

•Better for guys hosting their big website/web apps

•You don't have to buy land and get servers, easy setups are available; just buy it, everything will be handled by IaaS providers

•Increased reliability means if one server fails the other server will take over the data.

•No worry about securing your own data centres,  the provider will do that for you.

                        Just Host !!!

IaaS examples

Cloud services used for hosting websites etc. Eg:Amazon Web services,Oracle ...many more
