This service is crucial for apps that need fast, low-latency access to their data.
Amazon EFS (Elastic File System)
Amazon EFS offers scalable file storage for Linux-based workloads. Unlike EBS, which connects to a single EC2 instance, EFS can be shared across multiple EC2 instances at once. This makes it good for things like content management systems or developer environments where many users need to access the same files. You can scale your file system up or down without any effort. It simply grows as you add more data.
3. Database Services: Powering Modern Applications
Every application needs a place to store and retrieve data. AWS offers a wide range of database services, managed for you. This frees you up to focus on your app, not on database maintenance.
Amazon RDS (Relational Database Service)
Amazon RDS makes it easy to set up, operate, and scale a relational database in the cloud. It supports popular database engines like MySQL, PostgreSQL, SQL Server, and Oracle. RDS handles tedious tasks like patching, backups, and scaling. For high availability, you can set up Multi-AZ deployments, meaning your database is duplicated in another data center. Learning about read replicas helps you scale for heavy read traffic.
Amazon DynamoDB: NoSQL at Scale
Amazon DynamoDB is a fast and flexible NoSQL database service. It’s perfect for apps that need consistent, single-digit millisecond response times, no matter the scale. Think online gaming, ad tech, or IoT. DynamoDB supports both key-value and document data models. You’ll need to learn how to design your data tables for efficient access patterns. It scales automatically to handle millions of requests per second.
Amazon Aurora: High-Performance Relational Database
Amazon Aurora is an AWS-built relational database that is compatible with MySQL and PostgreSQL. It offers the speed and availability of high-end commercial databases at a much lower cost. Aurora gives you up to five times the performance of standard MySQL and three times that of PostgreSQL. It’s also highly available and durable. Plus, you can even use serverless Aurora for databases that scale capacity up and down based on your app’s needs.
4. Networking and Content Delivery: Connecting and Accelerating
Connecting your cloud resources securely and delivering content quickly to users worldwide is vital. These services build the bridges and speed up your data flow across the internet.
Amazon VPC (Virtual Private Cloud)
Amazon VPC lets you set up your own isolated network in the AWS cloud. You get total control over your virtual network setting, including IP address ranges, subnets, and route tables. Security Groups and Network ACLs act like virtual firewalls, controlling traffic in and out of your instances. Understanding VPC is fundamental for creating secure and organized cloud setups. You’ll also explore ways to connect your own data center to your VPC using VPN or Direct Connect.
Elastic Load Balancing (ELB)
Elastic Load Balancing (ELB) automatically spreads incoming application traffic across multiple targets, like EC2 instances. This makes your applications more fault-tolerant. ELB comes in different types: Application Load Balancers (ALB) for HTTP/HTTPS traffic, Network Load Balancers (NLB) for extreme performance, and Gateway Load Balancers (GWLB) for third-party virtual appliances. Using ELB ensures your apps stay available and perform well even during traffic spikes.
Amazon CloudFront: Global Content Delivery Network (CDN)
Amazon CloudFront is a fast global Content Delivery Network (CDN) service. It securely delivers your content to users with low latency and high transfer speeds. CloudFront uses a worldwide network of edge locations to cache your content closer to your users. This speeds up your website and reduces the load on your origin servers.
