With the continuous development of Internet technology, more and more enterprises begin to realize cloud hosting storage of data through cloud technology. Today's IT training will take a look at the learning method of zero-based entry cloud technology.

This article is not to teach you how to develop a website on AWS. Instead, it introduces all the technical services provided by AWS through a website example. You can have a very comprehensive understanding of AWS through conceptual learning and practical operation.

This article will start with a basic Web page, and then build a web application using extremely cheap ASW. Although the website is small, it doesn't matter. It can do anything you want. It can be said that the sparrow is small and complete.

The sample website is called "Daily Fortune". Every time the page is loaded, a wealth value will be displayed randomly, and an input box and a button are provided at the bottom of the page. Through these two components, new wealth data can be added to the random wealth list.

Basic knowledge about accounts.

Create an IAM user for your personal use.

Set MFA for root user and turn off API keys for all root users.

Set up a bill reminder so that you can know in time when the specified price is exceeded.

Use API credentials to configure AWSCLI for users.

Goal of this stage: You can use AWSCLI to query your AWS account information.

Basic knowledge of virtual host

Deploy EC2 virtual machine, and display a simple static web page that says "Daily Fortune Website will be launched soon".

Take a snapshot of the virtual machine, then delete the virtual machine, then deploy a new virtual machine from the snapshot, and select basic disk backup and disk recovery functions.

Goal of this stage: You can view the simple HTML page provided by EC2 instance.

Elastic telescopic configuration

Create an AMI from a virtual machine and put it into an elastic expansion group to ensure that at least one virtual machine is running.

Add an elastic load balancer to the virtual machine and achieve load balancing between the two available areas.

Goal of this stage: You can view simple HTML pages from two EC2 instances. If you close one of them at will, the website can still be accessed.

Database access

Create a DynamoDB database table, and manually perform data insertion and retrieval operations, and then perform the same operation through scripts on the local computer.

Reconstruct your static page into a daily wealth website, and use Node, PHP or Python to read and update the wealth data in AWSDynamoDB data table.
