Beginning AWS, Why and How

AWS does everything. This the first step.

Cloud Platform Models

  • IaaS
  • SaaS
  • Paas
  • Serverless

Infrastructure as a Service (IaaS)

  • Iaas provides access to virtualized computer resources over an Internet connection.
  • IaaS products give you direct access to a provider’s compute, storage, and networking assets.
  • You can use IaaS to replace every physical element in your computing setup except
    • those required to establish and maintain Internet connectivity and
    • those required to provide nonvirtualized services (such as printing)


  1. Billing can become complex because some services are billed at different rates and within different time frames.
  2. Systems-management monitoring becomes more difficult.
  3. A lag often occurs between when a change in service is needed and when the host provides it.
  4. Host downtime is unfixable.

Platform as a Service (PaaS)

  • PaaS is more of a development solution than a production environment solution.
  • It hides the complexity of the infrastructure that runs it
  • For example, Windows is a particular kind of platform. The virtual platform provided by PaaS allows a customer to develop, run, and manage applications of all sorts.

Software as a Service (SaaS)

  • It’s also called software on demand.
  • It’s all about cloud-based applications.
  • It offers services meant to be accessed by end users.
  • A client typically accesses the application using a local application, such as a browser. The browser runs on local hardware, but the application runs on the host hardware.
  • The host, Amazon, maintains the software, provides the required licenses, and does all the other work needed to make the software available.

Serverless workload

  • No need to manage a server
  • Inherent scaling and HA
  • No idle capacity - lower cost
  • Quick deployment and updates
  • Pay-as-you-go model
  • Event/mocroservices architectures

Benefits of Cloud Solution

  1. Infrastructure automation is a big advantage of the cloud compared to hosting on-premises.
  2. Scalability A scalable service will automatically grow in capacity to seamlessly meet any changes in demand.
  3. Elasticity. Services are built to be easily and automatically resized,

What is AWS

Amazon Web Services (AWS) is a platform of web services that offers solutions for computing, storing, and networking, at different layers of abstraction.

  • Computing
  • Storing
  • Networking

Benefits from AWS


Major AWS Competitors

  • Google Cloud Platform: the prominence of machine learning services that aren’t found in AWS.

  • Microsoft Azure has strong SQL database-management support as well as the connection with the Windows platform that businesses may want to maintain.

  • AWS has more to offer in the way of the Internet of Things (IoT), applications, and mobile services.

What AWS Free Tier provides

  • The 12-Month Free Tier
  • Permanently Free Services

The 12-Month Free Tier

Product Pricing

  1. Each AWS service has its own web page dedicated to pricing.
  2. Paying less if buy in bulk
  3. Server licensing costs are included in the hourly EC2 rates.

Product cost calculators

  1. Simple Monthly Calculator
    • http://calculator
    • what running any combination of AWS resources will cost you
  2. Total Cost of Ownership Calculator
    • tco-calculator

Billing and Cost Management

  1. The AWS Billing Dashboard
    • previous
    • current
    • forecast
  2. AWS Budgets

Service Limits

  1. run only 20 on-demand and 20 reserved instances of the EC2 m5.large instance type at any one time within a single AWS Region
  2. protect customers from having automated processes accidentally (or maliciously) launch resources that generate unsustainable costs.
  3. Most service limits are soft (or adjustable)—meaning that you can manually request that AWS increase a limit for your account.

Getting Support on AWS

  1. Support plans: premiumsupport
  2. AWS Professional Services

AWS Infrastructure

Regionally Based Services

  • Locate your infrastructure geographically closer to your users to allow access with the lowest possible latency
  • Locate your infrastructure within national borders to meet regulatory compliance with legal and banking rules
  • Isolate groups of resources from each other and from larger networks to allow the greatest possible security

Globally Based Services

  • AWS Identity and Access Management (IAM)
  • Amazon CloudFront (CDN, content delivery network)
  • Amazon S3 buckets

Availability Zones and High Availability

  • A resource running without backup is known as a single point of failure.
  • The only effective protection against failure is redundancy.
  • Geographically parallel distribute your resources across remote locations. Cloud is easier and cheaper.
  • Autoscaling can be configured to replace or replicate a resource to ensure that a predefined service level is maintained.
  • Load balancing orchestrates the use of multiple parallel resources to direct user requests to the server resource that’s best able to provide a successful experience.

Edge Locations

  • An edge location is a site where AWS deploys physical server infrastructure to provide lowlatency user access to Amazon-based data.
  • Edge locations are smaller set of roles and stock a much narrower set of hardware.
  • the best-known tenant of edge locations is CloudFront, Amazon’s CDN service.
  • Amazon Route 53: Amazon’s Domain Name System (DNS) administration tool for managing domain name registration and traffic routing
  • AWS Shield A managed service for countering the threat of distributed denial-of-service (DDoS) attacks against your AWS-based infrastructure
  • **AWS Web Application Firewall (WAF) **A managed service for protecting web applications from web-based threats
  • Lambda@Edge A tool designed to use the serverless power of Lambda to customize CloudFront behavior

The AWS Shared Responsibility Model

  • Managed Resources: A managed cloud service will “hide” all or some of the underlying configuration and administration work needed to keep things running, leaving you free to focus on the “business” end of your project. Beanstalk handles the instances, storage, databases, and networking headaches—including ongoing patches and administration—invisibly.

  • Unmanaged Resources: think about EC2. if you can edit it, you own it.

AWS Acceptable Use Policy

Amazon reserves the right to suspend or even terminate your use of its services should you engage in illegal, insecure, or abusive activities (including the sending of spam and related mass mailings).

Sign Up

To use AWS, you must have two levels of access:

  1. User: The first level grants you user-level access to the various services.

  2. Developer: The second level, which you must obtain after getting userlevel access, is developer access. Amazon wants to know who is using its service for a number of reasons, including billing, which means you need a developer ID to obtain the required programmatic access to services.

Most used AWS Services

  1. Amazon S3: storing and retrieving the data
  2. EC2 [Elastic Compute Cloud]: develop and deploy applications quickly and effectively for a low cost.
  3. AWS Lambda: run code without any server.
  4. Glacier: online web storage service that provides you with low cost.
  5. Amazon SNS [Simple Notification Service]: manages and delivers the messages or notifications to the users and clients from any cloud platform.
  6. Amazon Elastic Beanstalk: Developers can easily deploy the services and web applications.
  7. DynamoDB: NOSQL DB
  8. Amazon RDS [Relational Database Service]
  9. Amazon ElastiCache: a memory cache system service on the cloud and supports Redis and Memcached.
  10. Amazon Redshift: a fully managed data warehouse service in the cloud.

Official 10-Minute Tutorials


1. Control your AWS Costs

  • AWS Budgets is cost control tool that allows you to create custom cost budgets that alert you when you exceed your budgeted threshold.
  • AWS Budgets has a Free Tier limit of 62 budget days per month
  • It is a best practice to create a total monthly cost budget for each AWS account you use.

In toturail, I created three buget, they’re:

  1. When actual costs exceed 50%
  2. When forecasted costs exceed 100%
  3. When actual costs exceed 100%

2. Launch a Linux Virtual Machine

  • Amazon Elastic Compute Cloud (EC2): create and run virtual machines in the cloud.
  • Amazon Machine Image (AMI)
  • Save your key pair in the .ssh sub-directory from your home directory (ex. ~/.ssh/MyKeyPair.pem).
      mv ~/Downloads/MyKeyPair.pem ~/.ssh/MyKeyPair.pem


  1. Permission issue

    Permissions 0644 for ‘MyKeyPair.pem’ are too open. It is required that your private key files are NOT accessible by others. This private key will be ignored.


     chmod 400 MyKeyPair.pem

3. Deploy Code to a Virtual Machine

  • AWS CodeDeploy, a service that automates code deployments to AWS or on-premises servers
  • To deploy code to virtual machines that you create and manage with Amazon EC2.

4. Deploy and host a ReactJS app

  • AWS Amplify Console will now build your source code and deploy your app at

  • With AWS Amplify Console, you can continuously deploy your application in the cloud and host it on a globally available CDN.

5. Create and Connect to a MySQL Database

  • Amazon RDS
  • If you want to visit db from your local client, need to set Public accessibility to Yes.
