Core AWS Services Explained

Compute Services

Alright, let's kick things off with the compute services. These are the workhorses of AWS, providing the raw power you need to run your applications. The compute services are designed to handle the core operations of any program or software. The compute services is important for users to understand because this is the place where all the program processes happen. You can have multiple compute services depending on your needs. The compute services can run applications such as games, websites, software, etc. It is important to know about EC2, Lambda, Elastic Beanstalk, and ECS/EKS

  • Amazon EC2 (Elastic Compute Cloud): Think of EC2 as virtual servers in the cloud. You can choose the operating system, storage, networking, and more. It's like having your own physical server, but with the flexibility and scalability of AWS. With EC2, you're in control of your instances, deciding when to start, stop, scale, and configure them to fit your workload. It is a fantastic option when you need direct control over your server environment.

    • Instances: These are the virtual servers themselves, available in various sizes and configurations (like t2.micro or c5.large) to suit different needs. You can choose from many instance types optimized for different workloads, such as general-purpose, compute-optimized, memory-optimized, and storage-optimized instances.

    • AMIs (Amazon Machine Images): These are pre-configured templates that you use to launch EC2 instances. AMIs include an operating system, application server, and applications.

    • Auto Scaling: This feature automatically adjusts the number of EC2 instances based on demand. If your website traffic spikes, Auto Scaling can spin up more instances to handle the load, ensuring your application remains responsive.

  • AWS Lambda: This is a serverless compute service that lets you run code without provisioning or managing servers. You only pay for the compute time you consume. Lambda is ideal for event-driven applications, such as processing image uploads or responding to changes in your database. With Lambda, you upload your code, and it runs in response to triggers like changes in data, website clicks, or updates to database tables. Lambda handles all the underlying infrastructure.

  • AWS Elastic Beanstalk: This is a platform-as-a-service (PaaS) that makes it easy to deploy and manage web applications. You upload your code, and Elastic Beanstalk handles the capacity provisioning, load balancing, auto-scaling, and application health monitoring. Beanstalk supports many programming languages and platforms, simplifying the deployment process.

  • Amazon ECS (Elastic Container Service) and Amazon EKS (Elastic Kubernetes Service): These are container orchestration services. ECS is a fully managed container service, while EKS lets you run Kubernetes on AWS. Both services allow you to easily run, stop, and manage containers on a cluster of EC2 instances. This is great for modern application development.

    • Containers: These are packages of software that contain all the necessary components to run your application. They provide a consistent environment across different infrastructures.

Storage Services

Storage is a fundamental aspect of any cloud setup. AWS offers various storage options to meet diverse needs, from simple object storage to block storage and archival storage. The storage services are designed to address a variety of data storage requirements. The types of storage depend on the application usage. The storage is often very inexpensive, depending on how often the data is accessed. It is important to know about S3, EBS, EFS, and Glacier.

  • Amazon S3 (Simple Storage Service): S3 is object storage designed for storing and retrieving any amount of data. It's highly scalable, durable, and cost-effective. S3 is perfect for storing files, images, videos, and other digital assets. You can easily store, retrieve, and manage your data with S3. It's the go-to choice for backing up data and hosting static websites.

    • Buckets: These are containers for your objects in S3. You organize your data by creating buckets and then uploading objects (files) to them.

    • Object: This is the fundamental storage unit in S3. An object consists of the data itself, metadata describing the data, and a key (unique identifier).

  • Amazon EBS (Elastic Block Storage): EBS provides block-level storage volumes for use with EC2 instances. You can think of it as virtual hard drives that you attach to your EC2 instances. EBS is ideal for applications that require frequent access to data, such as databases and file systems. It offers high performance and durability.

    • Volumes: These are the actual storage devices you create and attach to your EC2 instances. You can choose from various volume types based on performance and cost requirements.

  • Amazon EFS (Elastic File System): EFS provides a fully managed, scalable file system that can be used with EC2 instances. It's designed for workloads that require shared access to files. EFS is an excellent choice for applications like content management systems, web serving, and big data analysis.

  • Amazon Glacier: This is a low-cost storage service for data archiving and long-term backup. It's designed for data that is infrequently accessed. Glacier offers very low storage costs, but retrieval times can vary depending on the retrieval option you choose.

Database Services

Databases are the backbone of many applications, and AWS offers a wide range of database services to meet various needs. The database services are used to store, manage, and retrieve data. The database services often require dedicated infrastructure. It is important to know about RDS, DynamoDB, and Aurora.

  • Amazon RDS (Relational Database Service): RDS makes it easy to set up, operate, and scale relational databases in the cloud. It supports various database engines, including MySQL, PostgreSQL, Oracle, and SQL Server. RDS handles database administration tasks, such as patching and backups, so you can focus on your applications.

    • Database Instances: These are the virtual database servers you create using RDS. You can customize the instance type, storage, and other settings to meet your needs.

  • Amazon DynamoDB: This is a fully managed NoSQL database service that provides fast and predictable performance. It's designed for applications that require low latency and high scalability. DynamoDB is a great choice for applications like gaming, mobile apps, and IoT.

    • Tables: These are the containers for your data in DynamoDB. Each table consists of items, which are collections of attributes.

  • Amazon Aurora: This is a MySQL and PostgreSQL-compatible relational database built for the cloud. It offers significantly improved performance and availability compared to traditional databases. Aurora is a great choice for mission-critical applications.

Networking and Content Delivery Services

These services help you connect your applications to the internet and deliver content to users quickly and efficiently. The networking and content delivery services help your application to be deployed efficiently. The services have many security mechanisms. It is important to know about VPC, CloudFront, and Route 53.

  • Amazon VPC (Virtual Private Cloud): VPC lets you provision a logically isolated section of the AWS Cloud where you can launch AWS resources. You have complete control over your virtual networking environment, including the selection of your IP address range, creation of subnets, and configuration of route tables and network gateways. VPC provides a secure and private network for your AWS resources.

    • Subnets: These are subdivisions of your VPC's IP address range. You can use subnets to segment your network and isolate resources.

    • Security Groups: These are virtual firewalls that control inbound and outbound traffic to your EC2 instances.

    • Network ACLs (Access Control Lists): These are another layer of security that controls traffic at the subnet level.

  • Amazon CloudFront: This is a content delivery network (CDN) service that delivers content to users with low latency and high transfer speeds. CloudFront caches your content at edge locations around the world, so users can access it quickly. It is optimized to speed up the loading of your web pages and applications.
