#beginners #aws #s3 #cloud

Hi folks,
Been a while you read from me, I have just been heating up the stove.
Today I will be writing on one of the most popular and exciting cloud computing services offered by Amazon, The Amazon S3. The S3 is also known as Simple Storage Service and it is one of the services used by Netflix to store videos and deliver content to users round the world(before building their own CDN).
S3 is one of the main building blocks of Amazon web services and it is known for its infinity scaling storage. Most website use the Amazon S3 at its back bone. The S3 is known for its reliability, scalabity and avalability.

Use cases of Amazon S3

1-Popular for its storage and backup
2-Disaster recovery purposes
3-Archieving and retrieving of files
4-Hybrid cloud storage
5-Application hosting
6-Media hosting
7-Data lakes & big data analytics
8-Hosting of static website

Lets take a deep dive with Amazon S3
The S3 was built to allow people store files into what is known as buckets which is seen as top level directories. The files stored in the S3 buckets is known as objects. When creating and naming buckets in S3, the name of the bucket must be a globally unique one(i.e it must be named differently from what anyone has used before). The S3 is a global service, however, the buckets are created in a region.
There are things to consider when naming a S3 bucket
1-No use of special character such as underscore, capital letters
2-The name must start with a lower case or number
3-The name is usually between 3-63 characters long

The S3 object files contain what is called key which are very long names with slashes and are made up of prefix+object name. The maximum object size that can be uploaded to the S3 bucket is 5TB.

I will be showing you how to make use of the Amazon S3 through this hands on project, follow along.
