The concept of using cloud technology in business is a pretty hot topic for enterprises. If you are planning to switch your business to the cloud, it is important to understand the difference and advantages of various services in the cloud. To start with there are usually three models in cloud service as SaaS, PaaS, and IaaS. These usually go by the name as Software as Service, Platform as Service and Infrastructure as Service. Each of these has its own benefit to choose for your organization.
Now let us see the common examples of SaaS, PaaS, and IaaS:
For Software as Service platform type: Cisco WebEx, Dropbox, Google Apps are the examples of SaaS.
For Platform as Service platform type: Microsoft Azure, AWS Elastic Beanstalk, Google Apps Engine are the common examples of PaaS.
For Infrastructure as Service platform type: Amazon Web Services, Microsoft Azure, Google Compute engine.
Now let us see the advantage of SaaS, PaaS, and IaaS:
SaaS is greatly beneficial for companies and employees where the time and money spent is reduced. There is no need to install, upgrade and manage the software and gives you more time to attend more pressing important issues within the organization.
PaaS has numerous advantages irrespective of the size of your company. PaaS has the ability to develop a customized app without the issue of maintaining the software. This greatly reduces the amount of coding required, automates business policy and makes development and deployment of apps cost effective.
IaaS is the most flexible cloud computing model. This model allows for the automated deployment of storage, networking, and servers. You can purchase the hardware and resources based on the consumption and as per need. Unlike SaaS and PaaS, IaaS users are responsible for managing aspects such as applications, runtime, OSes, middleware, and data.
