In this episode, I tried to explain the concept of Cloud Computing History of Cloud, Cloud Services like IaaS, SaaS, PaaS, DaaS, FaaS etc
The cloud refers to servers that are accessed over the Internet, and the software and databases that run on those servers.
We have Different Cloud Service Providers like Google, Amazon, Microsoft Azure etc.
Amazon Services like EC2(Elastic Computing Cloud). SS3(Simple Storage Service)
Eg of IaaS :DigitalOcean, Linode, Amazon Web Services (AWS), Microsoft Azure, Google Compute Engine (GCE), Rackspace, and Cisco Metacloud.
In this model, a company rents the servers and storage they need from a cloud provider. They then use that cloud infrastructure to build their applications.
For example AWS EC2 which has only the hardware and you select the base OS to be installed. If you want to install Hadoop on that you have to do it yourself, it's just the base infrastructure AWS has provided.
SAAS: Software As a Service
Simple, cost-effective development and deployment of apps
Scalable
Highly available
Developers can customize apps without the headache of maintaining the software
Significant reduction in the amount of coding needed
Automation of business policy
Easy migration to the hybrid model
Eg of SAAS:
Gmail
Google Drive
Google Calendar
Google Sheets
Hangouts
Google App Engine
