Important definitions
What is AWS region?
AWS Regions are the broadest geographic category that defines the physical locations of AWS data centres. Currently, there are 22 regions dispersed worldwide across North America, South America, Europe, China, Africa, Asia Pacific and the Middle East. All Regions are isolated and independent of one another.
Every region consists of multiple, separate Availability Zones within a geographic area. AWS offers Regions with a multiple AZ design – unlike other cloud providers who see a region as one single data centre. It’s important to pay attention to the services offered in each Region and AZ so you can make sure you are getting the most optimal service in your area.
What is IAM?
Identity and Access Management is a web service that helps you securely control access to AWS resources for your users. You use IAM to control who can use your AWS resources (authentication) and how they can use resources (authorization).
through IAM you can control people authorization.
What is EC2?
Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides secure, resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers. Amazon EC2’s simple web service interface allows you to obtain and configure capacity with minimal friction. It provides you with complete control of your computing resources and lets you run on Amazon’s proven computing environment.
Amazon EC2 offers the broadest and deepest compute platform with a choice of processor, storage, networking, operating system, and purchase model. We offer the fastest processors in the cloud and we are the only cloud with 400 Gbps ethernet networking. We have the most powerful GPU instances for machine learning training and graphics workloads, as well as the lowest cost-per-inference instances in the cloud. More SAP, HPC, Machine Learning, and Windows workloads run on AWS than any other cloud
What is S3?
Amazon S3 (Simple Storage Service) is a basic cloud object storage platform.
How does S3 differ from other cloud storage providers?
- S3 does not behave like a file system, it is an object store which basically means that it treats each file as an object unlike traditional storage. It does not talk the language of block/sector etc.
- You can directly run a static website with the files stored on S3.
- It provides 99.999999999% reliability which makes it super slow for read/writes but super reliable. This essentially rules out using it as a remote attached secondary disk drive. Primarily usable as backup storage.
- You have a lesser redundancy option within S3 for less important backups/cold storage which will reduce the storage cost even further.
- Easily turn on encryption for all your data on S3.
- Easily integrates with a ton of other services within the AWS cloud allowing you to expand your cloud usage without moving data around all the time.
If you ever need any assistance in setting up anything on the cloud, you could reach out to an AWS Managed Service Provider
What is VPC?
Amazon Virtual Private Cloud (Amazon VPC) enables you to launch AWS resources into a virtual network that you've defined. This virtual network closely resembles a traditional network that you'd operate in your own data center, with the benefits of using the scalable infrastructure of AWS.
