Overview OF AWS

AWS Introducing 

In 2006, Amazon internet Services (AWS) began providing IT infrastructure services to businesses as internet services—now usually called cloud computing. one in all the key advantages of cloud computing is that the opportunity to interchange up-front capital infrastructure expenses with low variable prices that scale with your business. With the cloud, businesses do not have to be compelled to set up for and procure servers and different IT infrastructure weeks or months before. Instead, they will instantly spin up lots of or thousands of servers in minutes and deliver results quicker.
Today, AWS provides an extremely reliable, scalable, inexpensive infrastructure platform within the cloud that powers hundreds of thousands of companies in a hundred ninety countries around the world.

The AWS Cloud provides a broad set of infrastructure services, like computing power, storage
options, networking, and databases that area unit delivered as a utility: on-demand, on the market in seconds, with pay-as-you-go valuation. From knowledge reposition to readying tools, directories to content delivery, over ninety AWS services area unit on the market. New services will be provisioned quickly, while not the direct capital expense. this permits enterprises, start-ups, tiny and medium-sized businesses, and customers in the public sector to access the building blocks they have to reply quickly to ever-changing business requirements. This whitepaper provides you with a summary of the advantages of the AWS Cloud and introduces you to the services that structure the platform.

Amazon internet Services (AWS) provides on-demand computing resources and services within the cloud, with pay-as-you-go valuation. as an example, we will be able to run a server on AWS that you just can go browsing to, configure, secure, and run even as you'd a server that’s sitting ahead of you. The whole construct builds on prime of the cloud computing principle. It provides IT infrastructure and different services over the web.

And it’s usually used for:
Store public or non-public knowledge.
Host a static website. These websites use client-side technologies (such as markup language, CSS, and JavaScript) to show content that doesn’t modification ofttimes. A static website doesn’t need server-side technologies (such as PHP and ASP.NET).
Host a dynamic website or internet app. 

AWS Cloud formation

These websites embrace classic three-tier applications, with the web, application, and information tiersUsing cook with AWS CloudFormation Whenever you employ AWS CloudFormation to provision Amazon Elastic Cloud cipher (EC2) instances, you have a variety of choices for deploying and configuring computer code applications to those instances. you'll be able to build a custom AMI, run user knowledge scripts, or use a configuration management tool, like cook or Puppet. Each option will have an effect on instance begin time and computer code maintenance problems on those instances. the subsequent walkthrough focuses on victimization cook, a configuration management tool, with AWS CloudFormation. For more information concerning custom AMIs or user knowledge scripts, see Amazon Machine pictures (AMI) or Launching Instances with User knowledge within the Amazon EC2 user guide. With Chef, you'll be able to modify the reading of your computer code applications on Amazon EC2 instances instead of manually building varied scripts. By combining cook with AWS CloudFormation, you'll be able to systematically deploy and piece your AWS resources besides the computer code applications that run on prime of it, all from a single AWS

CloudFormation example.

For example, imagine you wish to deploy a WordPress weblog with a back-end information in AWS. you'll be able to use an AWS CloudFormation example to provide an internet server associated information. victimization identical example, you can also pass in data and commands to your internet server, with that you'll be able to install and run cook. By running Chef, you'll be able to use an instruction to put in and piece WordPress on your internet server. With this single AWS
CloudFormation example, you'll be able to quickly and simply get a WordPress weblog running in AWS. you'll be able to additionally consistently deploy identical setup by reusing identical example. These templates additionally give a history of your setup as you retell your templates.

Before you scan the walkthrough, note the subsequent items:

• If you begin with a bare-bones AMI and have tons of computer code applications to put in, bootstrapping your instances will take time. If you would like to decrease the bootstrapping time, produce a custom AMI that already includes several of the computer code applications that you just need.• the subsequent walkthrough assumes familiarity with cook and isn't supposed to be a tutorial on victimization cook. Also, to demonstrate the way to use cook, we tend to use a WordPress instruction. However, the instruction is meant for demonstration functions solely and isn't maintained by AWS from OnlineITGuru at AWS Online Course
