7 fundamental concepts you should know when learning about Amazon Web Services

When learning about Amazon Web Services (AWS), you should understand and master the basic concepts to effectively leverage the AWS cloud system. Below are some basic concepts you should know as you explore AWS.

7 fundamental concepts you should know when learning about Amazon Web Service

Amazon Web Service (AWS) is not just a simple cloud service but a complex ecosystem with hundreds of different services and concepts. When starting to learn about AWS, it’s important to master the basic concepts. In this article, we will go over 7 basic concepts you need to know when learning about Amazon Web Services.


AWS divides its infrastructure into regions around the world. Each region is a separate geographic area. It consists of one or more data centers. Separating into regions helps AWS provide services with high performance and better reliability. Users need to know about this concept to choose the region that suits their needs.

Users should understand the basic concepts of AWS

Availability Zones (AZs)

Each AWS Region is divided into Availability Zones (AZs) – independent data centers with their own infrastructure and power sources. AZs in the same area are often connected by private networks. It can also provide services with high reliability and stable uptime. Using multiple AZs in the same region helps you build fault-tolerant applications and ensure stable operation even if problems occur at one AZ.

VPC (Virtual Private Cloud)

Virtual Private Cloud (VPC) is a service developed by Amazon Web Services (AWS). It allows users to create a private cloud to deploy their resources and applications in a controlled and secure environment.

VPC is an important concept when learning about AWS

When you create a VPC, you can define the network’s IP, and create routing tables, and firewall rules to control network traffic. In this way, VPC helps you create a virtual network environment similar to a virtual private network in the AWS cloud environment.

EC2 (Elastic Compute Cloud)

EC2 (Elastic Compute Cloud) can help users rent virtual servers, also known as instances, to run the applications in the cloud. EC2 allows you to choose the type of virtual machine with different options for CPU, memory, storage, and networking. You can flexibly increase or decrease the number of virtual machines to meet the needs of your applications: small applications to large and resource-demanding applications. EC2 also provides security and control features, allowing users to manage access to virtual machines and encrypt data.

S3 (Simple Storage Service)

S3 allows users to store and access data from anywhere on the Internet. S3 provides a flexible and sustainable way to store data, from media data like images and videos to media data and big data. Users can upload and download data from S3 through the web interface or AWS API.

S3 also provides security features, including data-at-rest encryption, policy-based access control, and data activity tracking. This helps ensure that your data is stored safely and securely in the AWS cloud.

IAM (Identity and Access Management)

IAM (Identity and Access Management) is an identity and access management service in Amazon Web Services (AWS) that allows users to control and manage access to their resources in the cloud.

IAM allows users to control and manage access to their resources in the cloud

With IAM, you can create and manage users, user groups, and roles, defining their permissions for specific resources on AWS. You can control access to services like EC2, S3, and RDS from AWS.

IAM provides security features, including multi-factor authentication, activity tracking, and logging, to help users protect their resources from security threats and prevent security breaches. At the same time, IAM also helps increase compliance with security regulations and risk management in AWS cloud environments.

RDS (Relational Database Service)

RDS (Relational Database Service) is a service that provides and manages relational databases on the cloud of Amazon Web Services (AWS).

RDS helps users to deploy, manage, and scale relational databases such as MySQL, PostgreSQL, SQL Server, Oracle, and Amazon Aurora on the AWS cloud.

With RDS, you don’t need to worry about database management, like hardware configuration, backing up data, and restoring data from replicas. RDS automatically manages these tasks, saving you time and effort.

Learning about Amazon Web Services (AWS) not only helps you master AWS services but also opens a new door to how to approach cloud technology. By understanding basic concepts such as Regions, EC2, S3, IAM, VPC, and RDS, you will have a detailed overview of how to manage and optimize your infrastructure on the AWS cloud. At the same time, applying this knowledge into practice will also help you improve your skills and work experience in modern information technology.
