There are differing types of cloud computing and it's important for us to be ready to recognize them
Infrastructure as a service (IaaS)
This is to produce the building blocks for cloud IT.
This iaas we're visiting provide networking computers and data space for storing in its raw form and using these building blocks deals building legos we're visiting tend a really high level of flexibility and that we can easily understand how we will migrate from traditional on-premises IT to the cloud
Platform as a Service (PaaS)
This we're visiting remove the requirement for your organization to manage the underlying infrastructure and you'll just specialize in the deployment and management of your applications so one step even further is software as a service or sas this can be a completed product that's visiting be run and managed by the service provider.
Let's take an example on premises you are going to manage everything so your applications, your data, your runtime your middleware the software, virtualization, servers, storage and networking and that is plenty.
Iis so infrastructure as a service (Iaas) we're visiting manage the applying the info the runtime the middleware and therefore the os but all the virtualization servers storage and networking are visiting be managed by others and in our case aws.
Platform as a service (PaaS) we manage even less so everything from the runtime to the networking is managed by aws and therefore the only thing we care about once we use a platform as a service is our application and our data.
Finally well if you're using software as a service (SaaS) everything goes to be managed by aws.
Example of Cloud Computing Types
Infrastructure as a service (Iaas) Well how does it translate well with IIS we will use amazon ec2 on Aws but we've got other services like Google, Cloud, Azure Rackspace, Digital Ocean & Lynode which is able to provide us a cloud computing infrastructure as a service
Platform as a service (PaaS) platform as a service also exists on aws with elastic beanstalk and we'll see of these services obviously during this course and out of doors of aws we've heroku, google app engine and windows azure.
Software as a service (SaaS) software as a service we even have this on aws that represents many services of aws as an example recognition once we want to try to to some machine learning but we've been using it furthermore within the world with google apps like gmail or dropbox or zoom for your meetings.
The clouds have different flavors but one thing is common is that the pricing is incredibly different.
You know aws has three pricing fundamentals.
It will follow the pay as you go pricing model.
So for the compute which represents various services we're visiting pay money for the precise compute time.
The storage we're visiting get the precise amount of information stored within the cloud.
The networking we're visiting only pay when the info leaves the cloud any data that goes into the cloud is free.
This solves the expensive issue of traditional IT.
