AWS 5 main computing services

  1. Amazon Elastic Compute Cloud (EC2)
  2. AWS Lambda
  3. Amazon Elastic Container Service (ECS)
  4. Amazon Elastic Kubernetes Service (EKS)
  5. Amazon Elastic Beanstalk

All of these services run on EC2 but are configured to certain needs.


  • A virtual server where you can run applications and host services.
  • This is the most basic, flexible, and configurable service that Amazon provides.
  • Choose EC2 if AWS has no other service for your needs or if you want to manage your infrastructure


  • Event-driven computing service made for serverless applications
  • You don’t need to manage any servers.
  • Lets you write code in the form of Lambda Functions to perform a task in response to events.
  • Known as a FaaS (Function as a Service)


  • A container orchestration service that supports Docker containers
  • Has good integration with other AWS Services ( IAM, CloudWatch, ELB)
  • More managed than EC2 but less complex than EKS
  • Amazon’s platform for cluster management infrastructure (like Kubernetes but simpler)


  • This is Amazon’s managed Kubernetes service. Kubernetes is an open source container orchestration platform
  • Great choice to avoid AWS lock-in which makes it great for a multi-cloud strategy
  • makes it easy to run Kubernetes on AWS without needing to set up your own Kubernetes control plane or nodes.

Elastic Beanstalk:

  • A platform as a service (PaaS) that makes it easy to create applications in multiple languages
  • Automatically handles capacity provisioning, load balancing, and application health monitoring.
  • Easiest and simplest Solution

  2. Amazon Elastic Block Store (EBS)
  3. Amazon Elastic File System (EFS)
  4. Amazon Glacier
  5. AWS Storage Gateway

All of these services, except for Storage Gateway, run on S3 but are configured to certain needs.


  • A scalable object storage service for data archiving and backup.
  • Can store any type of objects which includes data lakes, and/or big data analytics.
  • S3 is often used as the data store for cloud-native applications, as well as for backups and big data projects.
  • Data is organized into buckets and identified within each bucket by a unique, user-assigned key.
  • Provides features like lifecycle management, encryption, and a robust permissions model.


  • A block storage service designed for use with Amazon EC2 instances.
  • Particularly good for databases or any workload that requires frequent reads/writes to storage.
  • Can be attached to an EC2 instance and used like a physical hard drive.


  • Managed file storage service that makes it easy to set up and scale file storage in the Amazon Cloud.
  • EFS is designed to be used with EC2 instances, and multiple instances can connect to the system at once.
  • Good for applications that require shared access to files and require a file system interface and file system semantics.


  • A secure, durable, and low-cost storage service for data archiving and long-term backup.
  • Designed to be really durable
  • Used to move infrequently accessed data off to a low-cost storage service.

Storage Gateway:

  • A hybrid cloud service that allows on-premises applications to access virtually unlimited cloud storage with the AWS cloud storage
  • Also good for local caching for low-latency access to hot data, then sync to AWS for durable storage.


AWS 5 main database services

  1. Amazon Relational Database Service (RDS)
  2. Amazon DynamoDB
  3. Amazon Redshift
  4. Amazon ElastiCache
  5. Amazon Neptune


  • Managed relational database service that supports several database engines (MySQL, PostgreSQL)
  • Automatically takes care of routine database tasks
  • Suited for applications that require complex queries and transaction capabilities.


  • A NoSQL database service for applications that need high-performance at any scale.
  • Has built-in security, backup and restore, and in-memory caching for internet-scale applications
  • Supports both key-value and document data models


  • A fully managed, petabyte-scale data warehousing service.
  • Used in conjunction with data analytics tools to allow analytical queries involving large datasets.
  • It has fast query due to columnar storage and parallel queries across multiple nodes


  • A fully managed in-memory data store service
  • improves the speed of web applications by allowing you to retrieve information from fast, managed, in-memory caches
  • Good for caching, session storage, gaming, geospatial services, real-time analytics, and queueing.


  • A managed graph database service
  • For applications that work with highly connected databases
  • Could be used to create knowledge graphs, fraud detection systems, recommendation engines, etc.


AWS 5 main network services

  1. Amazon Virtual Private Cloud (VPC)
  2. Amazon Route 53
  3. AWS Direct Connect
  4. Elastic Load Balancer (ELB)
  5. Amazon API Gateway


  • Provides an isolated virtual network where you can launch AWS resources to the AWS Cloud.
  • You can define your own IP address range, create subnets, configure route tables, and network gateways.
  • Has both IPv6 and IPv4 for most resources.

Route 53:

  • A Domain Name System (DNS) web service.
  • It’s has domain registration, domain routing, and health checking of resources within your environment.
  • It connects user requests to infrastructure running in AWS, like EC2 instances, or S3 buckets.
  • Also has domain registration services that allows you to transfer or register domain names.

Direct Connect:

  • Establishes a dedicated network connection from your premises to AWS.
  • In comparison to internet-based connections it can it reduces your network costs, increases bandwidth throughput, and provides just a more consistent network experience.


  • A load balancer for AWS targets (EC2, Containers, IP addresses, Lambda functions)
  • It ensures the delivery of the right amount of traffic to each target based on the capacity that you set.
  • Has three different load balancers: Application Load Balancer, Network Load Balancer, and Classic Load Balancer.

API Gateway:

  • A service for APIs.
  • Handles all the tasks (traffic management, authorization and access control, monitoring) involved in accepting and processing thousands of concurrent API calls.
  • Essentially the “front door” for applications in your backend.


AWS 5 main security services

  1. AWS Identity and Access Management (IAM)
  2. AWS Certificate Manager (ACM)

Trusted Advisor:

  • A resource that can help you reduce cost, increase performance, and improve security by optimizing your AWS environment
  • Provides real time guidance to help you provision your resources.

There are many other services provided by AWS across various domains, like IoT, Machine Learning, etc., which are not covered here.
