- Introduction of AWS Services
- Practice Exams
1.1. What is cloud computing?
A solution to provide IT resources through internet
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
Region
- 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
Note:
- The root user should only be used once and be protected with MFA
2.5. Questions and Answers
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.
