1.2. Summary

AWS Services:

  • Solution to provide IT resources through internet
  • Provide solutions for your business through internet: other aws services
  • The benefits of Cloud Computing(costs, time, speed and agility)
  • Deployment model: cloud-based, on-premises(private cloud), hybrid(cloud-based + on-premises)

Practition Level


2. Cloud concepts

2.1. Cloud Characteristics


2.2. Regions, Availability Zones, Edge Locations

Region and Availability Zone



  • Fully independent and isolated
  • Resource and service specific

Availability Zones(AZs)

  • Consist one or more physically seperated data centers
  • Connected through low-latency links
  • Fault tolerant
  • Allows for high availability

Edge location


2.3 Summary


2.4. AWS Management

You can manage your AWS Service by:

  • AWS Management Console ( Web Interface )
  • AWS Command Line Interface (CLI)
  • AWS SDKs : to access AWS services from popular programming languages

3. Amazon EC2

3.1. Amazon EC2 Instances

There are 5 types of EC2 Instances

  • General purpose: balanced resources(CPU, Memory, Networking, Storage)
  • Compute Optimized: optimized for CPU - WebServer/Game Server
  • Memory Optimized: optimized for memory - Database
  • Accelerated Computing: use accelerate hardwares, eg: GPU - graphic applications/ streaming
  • Storage optimized: optimize for high frequency online transaction processing(FOTP) and high input output operations per seconds(IOPS) - Data warehouse/Distributed File System



3.2. Amazon EC2 Pricing


4. AWS Compute Services

4.1 AWS Compute Options

There are 3 type of compute options

  • Compute: Amazon EC2
  • Container: EKS(Amazon Elastic Kubernetes Service), ECS(Amazon Elastic Container Service)
  • Serverless: AWS Lambda

4.1.1. Amazon EC2

You should use when you have:

  • compute-intensive or memory-intensive applications
  • application that run more than 15 mins

4.1.2. Container

You should use when you have:

  • compute-intensive workloads
  • a small application that runs under in 15 minutes but is compute intensive

4.1.3. Serverless

You should use when:

  • want to focus only on your code and not on infrastructure
  • applications less compute intensive
  • applications that you are running or building small, simple, or modular
  • using multiple AWS services where one service might need to call another service
  • applications that don’t run longer than 15 minutes.
