Cloud Computing


IAAS (Infrastructure as a Service)

By this, you get to access the Operating Systems because when you get a cloud server by the provider, you choose an operating system on which you get 100 % access on that cloud server. It means you can do anything with the server without managing or monitoring it. All you have to take care of applications, data, runtime, middleware, and operating systems and the rest they will like virtualization, storage, network, and servers.

PAAS (platform as a Service)

In this only you need is a platform to perform although you don’t get the access over the cloud computing server in this but you all you have to do is simply upload your website on it, without any installation or handling any file under of any kind of cloud computing software.

All you need to manage is your data and applications.

 

SAAS (Software as a Service)

In this, you don't get a server nor user interface but a software. You don't need to manage anything and can use your software as you want to. Only the software you get you to have to pay for that. E.g., Salesforce Company.  

Deployment Models in Cloud Computing.

In these concepts of models tells how to deploy or upload your applications to some other place in the cloud or in what ways you lock and load your apps on the cloud .

1.Public Cloud

2.Hybrid Cloud

3.Private Cloud

 
  • Public Cloud

  When you start sharing your server by launching it or with a host with different people. By this, your server can be shared with lots of users.In this most of the time, your data is not safe because of sharing your server to many people. But some companies have some rules or policies that data is completely confidential and cannot be hosted to everyone on the public cloud.    
  • Hybrid Cloud

  Hybrid word in itself means a mixture or a mixed bag of many qualities. This kind of Architecture is basically a combination of public and private cloud in short. So if you use any app when you use both public and as well as private cloud both you come up with a Hybrid Cloud in Cloud Computing. In this manner, if you host a website so this can be done in Public Cloud.whereas at the same time you have some confidential data as well that you don't want to bring to light on the internet. Here you get the prerogative of using both the models at the same time. E.g., Idera Company.  
  • Private Cloud

  It is the kinda standalone system they give you your server in private or individually. They only deploy your operating System. And it's completely safe where we firstly care about data privacies. Here you have the privilege to host your servers privately. You buy your cloud and set up accordingly, and you can deploy your applications on it.
