An Overview of Amazon Web Services
                     An Overview of Amazon Web Services:
Amazon Web Services(AWS) is the market leader in IaaS (Infrastructure-as-a-
Service) and PaaS (Platform-as-a-Service) for cloud ecosystems, which can be 
combined to create a scalable cloud application without worrying about delays 
related to infrastructure provisioning (compute, storage, and network) and 
management.
With AWS you can select the specific solutions you need, and only pay for 
exactly what you use, resulting in lower capital expenditure and faster time to 
value without sacrificing application performance or user experience.
AWS allows doing the following things
 To run web and application servers in the cloud and host dynamic 
websites
 Store all types of files securely on the cloud and access them anytime 
and anywhere
 With Content Delivery Network (CDN),deliver files across the world 
quickly
 Use PostgreSQL, MySQL, Oracle or SQL Server databases to store 
information
 Send bulk email to customers
Server configuration and hosting
Deploy your army of servers with Amazon EC2. In just minutes bring virtual 
machines–called instances–online. Select AMI’s with operating system of your 
choice (Linux or Windows) and start deploying your clusters. There are three 
popular instance types when creating EC2 instances:
 Compute optimized. Used for instances that will require extremely high 
request rates, this configuration leverages industry leading processors.
 Memory optimized. These instances are built with the most efficient per-
GB memory cost.
 Storage optimized. Storage optimized EC2 instances access extremely 
fast SSD storage to serve data retrieval requests with lightning speed.
The title says that it's the hard way to learn to AWS, but it's actually not. By the 
end of this course, you will have the tools and concepts needed to begin 
learning more complex AWS topics. If you work hard, take your time, and build
skills, you willlearn how to deploy and manage your infrastructure 
on AWS cloud.
AWS EC2 Uses:
The main difference between  Amazon   EC2  and S3 is that EC2 is a computing 
service that allows companies to run servers in the cloud. While S3 is an object 
storage service used to store and retrieve data from AWS through the Internet.
Getting Started with AWS:
There is much more to the AWS universe than a short guide can detail. But 
familiarity with the above fundamentals prepares you to expand your 
organization’s infrastructure to the cloud, build an entirely new environment, 
and master the art of data logging to ensure compliance and security.
