[2021 AWSome Day] Summary of lecture contents

Lecture 1. Introduction to AWS Cloud

In this lecture, you will learn about the definition and value of cloud, the benefits of cloud computing, cloud deployment models, and AWS global infrastructure. - Ji-seon Kim, technical trainer, AWS

Cloud deployment model

On-premise, hybrid (on-premise + cloud), cloud

When migrating everything is a burden >> Hybrid

Regions and Availability Zones

Region is the location where AWS is hosted. Currently, there are 25 regions. Regions must consider data governance and latency. Service costs, service availability, and cost must be considered.

Availability Zone (AZ) is the availability zone of the data center, and one region consists of 2 to 3 availability zones. This is to protect against power outages and earthquakes.

Using the Seoul region means that the data center is located in the availability zone, not in actual Seoul.

Edge location POP >> Route 53, Cloud Front available

Connected to AWS’s global backbone network

AWS Edge Infrastructure

AWS Outposts, AWS Local Zones, AWS Wavelength

Interface to interact with AWS

AWS Management Console, AWS Command Line Interface (AWS CLI), Software Development Kit (SDK)

Automation of work becomes possible.

* Infrastructure as Code (IaC)

Lecture 2. Introduction to AWS Cloud Core Services 1: Computing

Learn about the most basic computing services of the AWS cloud. Introducing the world's most reliable computing services that help you develop, deploy, run, and scale applications. - Kibaek Lee, technical trainer, AWS

EC2

Supports work done on-premises as it is, can secure new server instances and reduce capacity by shortening boot time, provides only actual usage costs

Comparison of virtual machines and physical servers

Unlike physical servers that have load or traffic issues through over-provisioning, the infrastructure can be configured flexibly while statelessly checking the EC2 infrastructure through Cloudwatch.

You can access the necessary resources and expand or contract them.
There is no management overhead during control.
Can be flexibly combined with ELB, S3, and RDS.
99.9% availability
Low cost and secure
It is easy to run and use when needed.
It is easy to use through the AWS interface.

Instance family type classification

If you don't know which one to use, spend some time testing with general purpose (A1, T3, T3a, T2, M6g, MS) and then select the family type you need.

Amazon ESC

Container-based applications can be used with a simple API call.

* Kubernetes

AWS Lambda

You can also configure fully managed compute services, serverless services, and backend services, execute stateless code, and use lambda functions in response to events.

*Source bucket and destination bucket

Lecture 3. Introduction to AWS Cloud Core Services 2: Storage, Database

This lesson provides an overview of storage and introduces the various durable and cost-effective storage options that AWS offers. You will also learn about the benefits of purpose-built databases available through AWS. - Ji-seon Kim, technical trainer, AWS

storage

S3: Static web content can be stored and distributed. It is widely used in data lake and big data analysis.

EBS: A block storage service designed for use on EC2. Snapshots can be stored in S3 to prevent data loss, and snapshots can be shared for disaster recovery at any time.

database

AWS databases by purpose can be divided into relational, key-value, non-relational, non-relational in-memory, non-relational graph, and non-relational ledger. These include RDS, Aurora, DynamoDB, etc.

Lecture 4. Introduction to AWS Cloud Core Services 3: Networking, Security

This course introduces Amazon Virtual Private Cloud, networking, including Elastic Load Balancing, and security, which is a top priority for AWS. This module also covers the Shared Responsibility Model, which is an AWS service that is highly automated, highly available, and designed with a recognized security posture. - Kibaek Lee, technical trainer, AWS

networking

Amazon Virtual Private Cloud (VPC): A virtual network dedicated to your account. You can create a subnet and deploy services such as EC2 into that subnet. A public subnet is also possible, and must be a subnet with a public IP address. There is a layered defense.

ELB( Elastic Load Balancing ), Route53

security

Shared responsibility model, security in the cloud (AWS) and security in the cloud (customer) AWS IAM: Credentials and access, enforces security for AWS resources, no additional cost, no tracking of user activity AWS CloudTrail: Continuously tracks user activity and API. Trust Ad visor

Lecture 5. Innovate with AWS

In this course, you will learn about the various innovation opportunities available on the AWS Cloud through topics such as AWS machine learning, Internet of Things (IoT), and edge computing. Additionally, the course concludes with resources to take your learning journey to the next level and information on how to get started building on AWS. - Ji-seon Kim, technical trainer, AWS

Internet of Things (IoT)

Analysis services, connectivity and control services, device software, IoT GreenGrass

machine learning

Artificial Intelligence >> Machine Learning >> Lip Learning, SageMaker

blockchain

Data distributed processing technology, groups blocks in a chain over time. Distributed transaction ledger.

Distributed storage method, no need for middle managers

Amazon Managed Blockchain: ex) Nestle’s chain of origin case

*QLDB

Ground Station, Wavelength

Mobile Edge Computing:

A method of providing services by locating data close to users who want to use communication services, shortening transmission time
