AWS Service Overview Introduction
1. What is AWS?
Amazon Web Services (AWS) is a cloud platform provided by Amazon.com that provides services such as computing, storage, database, machine learning, security, and analytics. AWS makes resources available on demand to businesses and individuals without owning servers or data centers.
1.1 Global Infrastructure
AWS has data centers spread all over the world, which are divided into “regions” and “availability zones.” Regions are geographically independent, and Availability Zones exist within a region and are made up of different data centers. This allows AWS to provide high fault tolerance and availability.
2. AWS Main Construction and Operation Services
2.1 Amazon EC2
Amazon Elastic Compute Cloud (Amazon EC2) provides scalable computing power. Users can launch virtual machine instances on demand and scale them up or down.
Instance Type
EC2 offers a variety of instance types, optimized for different use cases. Examples include compute-optimized instances, memory-optimized instances, and storage-optimized instances.
Scaling and Load Balancing
You can use Auto Scaling and Elastic Load Balancing to automatically scale up or down instances based on application load.
2.2 Amazon S3
Amazon Simple Storage Service (Amazon S3) provides a scalable object storage service. Data is stored as “objects” within “buckets”.
Data Integrity and Durability
S3 provides high data integrity and durability, allowing you to store data without loss.
Data Lifecycle Management
You can set data lifecycle policies to automatically archive and delete objects.
2.3 AWS Lambda
AWS Lambda is a serverless computing service that allows you to run code directly. No need to provision or manage servers.
Event Driven
Lambda is event-driven and can execute functions in response to events such as new object uploads in S3 or table updates in DynamoDB.
Scaling
Lambda functions scale automatically and can process multiple events at the same time.
3. AWS Database Service
3.1 Amazon RDS
Amazon Relational Database Service (RDS) is a managed relational database service that supports multiple database engines including MySQL, PostgreSQL, MariaDB, Oracle, and Microsoft SQL Server.
Easy Management
RDS automates patch management, backup, recovery, and failover, reducing administrative overhead.
Scalability
Easily resize your database instance or add read replicas to improve read performance.
3.2 Amazon DynamoDB
Amazon DynamoDB is a fast, scalable NoSQL database service that delivers data at arbitrary scale with single-digit millisecond performance.
Fully Managed
DynamoDB is serverless and automatically handles hardware provisioning, setup, configuration, patching, backups, and cluster scaling.
Scalability and Performance
DynamoDB supports autoscaling and automatically adjusts capacity as traffic increases or decreases.
4. AWS Monitoring and Management Services
4.1 Amazon CloudWatch
Amazon CloudWatch provides monitoring of AWS resources and applications. Gain visibility into resource utilization, operational performance, and overall execution environment health.
Log Management
You can collect, monitor, analyze, and store log data using CloudWatch Logs.
Alarm
You can set alarms based on metrics and receive notifications when you detect unusual activity or conditions.
4.2 AWS Config
AWS Config is a service that assesses, monitors, and automates the configuration of AWS resources. Setting History
You can track resource configuration changes and view configuration history.
Compliance Assessment
Automatically assess and report on your organization’s compliance requirements.
5. AWS Security and Identity Services
5.1 AWS Identity and Access Management (IAM)
AWS Identity and Access Management (IAM) is a service for securely controlling access to AWS resources.
Users and Permissions
You can use IAM to create users and set policies that allow or deny access to specific AWS resources.
Roles and Access Management
You can use IAM roles to securely delegate permissions for AWS services to access other resources.
5.2 AWS Key Management Service (KMS)
AWS Key Management Service (KMS) is a service that securely creates and manages data encryption keys.
Key Management
KMS can be used to manage the lifecycle of encryption keys and audit key usage.
Using Keys
You can use KMS to encrypt and decrypt your data and integrate with other AWS services to increase the security of your data.
6. AWS Cost Management
6.1 AWS Cost Explorer
Use AWS Cost Explorer to perform detailed analysis of your AWS usage and costs and identify cost savings opportunities.
Usage and Cost Visibility
Understand cost and usage trends and identify cost drivers and savings opportunities.
Forecast and Budget
Forecast future costs and usage and set budgets for better cost control.
7. AWS Developer Tools
7.1 AWS CodeCommit
AWS CodeCommit is a fully managed source control service that allows enterprises to host Git repositories.
Security
You can control access to your repositories using AWS Identity and Access Management (IAM).
Scalability
Provides fast performance regardless of repository size.
7.2 AWS CodeBuild
AWS CodeBuild is a fully managed build service that compiles your source code, runs tests, and generates build artifacts.
Scalability
Build quickly, regardless of the size or complexity of your build project.
Alignment
You can integrate with other AWS services such as AWS CodePipeline to build continuous integration and delivery pipelines.
7.3 AWS CodeDeploy
AWS CodeDeploy is a service that automates application deployment, reducing errors and releasing new features faster.
Automatic Deployment
You can automatically deploy your application whenever there is a code change.
Scalability
It provides a consistent deployment process for applications of any size.
8. Other AWS Services
8.1 Amazon VPC
Amazon Virtual Private Cloud (VPC) is a virtual network for defining your network environment and launching resources within the AWS Cloud.
Security
Use VPC to control network traffic and leverage security groups and network ACLs to manage access to resources.
Customization
You can customize IP address ranges, subnets, routing tables, and network gateways.
8.2 AWS Lambda
AWS Lambda provides serverless computing and provides a platform for running your code.
Event Driven
You can execute code in response to events.
Scalability
Code runs in separate containers and scales automatically.
