Each Amazon S3 object has data, a key, and metadata. The object key (or key name) uniquely identifies the object in a bucket. Object metadata is a set of name-value pairs. You can set object metadata at the time you upload it.
An Amazon S3 bucket is a public cloud storage resource available in Amazon Web Services' (AWS) Simple Storage Service (S3), an object storage offering. Amazon S3 buckets, which are similar to file folders, store objects, which consist of data and its descriptive metadata.

How To Get Amazon S3 Access Keys
- Click on “My Account/Console” and select “Security Credentials”.

- Click “Show User Security Credentials” once the user is created.
Amazon EC2 uses public key cryptography to encrypt and decrypt login information. The public and private keys are known as a key pair. Public key cryptography enables you to securely access your instances using a private key instead of a password.
Amazon S3 is an object storage capable of storing very large objects, upto 5TB in size. Objects in S3 can be archived to Amazon Glacier which is a very cheap archival service. DynamoDB on the other hand is a NoSQL database that can be used as a key value or a document(schema less record) store.
Amazon Simple Storage Service (Amazon S3) is a scalable, high-speed, web-based cloud storage service designed for online backup and archiving of data and applications on Amazon Web Services.
Using Amazon S3
The Amazon S3 stores data as objects within buckets. An object consists of a file and optionally any metadata that describes that file. To store an object in Amazon S3, the user can upload the file that he/she wants to store in the bucket.The S3 cloud storage service gives a subscriber access to the same systems that Amazon uses to run its own websites. S3 enables customers to upload, store and download practically any file or object that is up to five terabytes (TB) in size, with the largest single upload capped at five gigabytes (GB).
With the AWS Free Usage Tier*, you can get started with Amazon S3 for free in all regions except the AWS GovCloud Region. Upon sign-up, new AWS customers receive 5 GB of Amazon S3 Standard storage, 20,000 Get Requests, 2,000 Put Requests, 15GB of data transfer in, and 15GB of data transfer out each month for one year.

Amazon Simple Storage Service (Amazon S3) is a scalable, high-speed, web-based cloud storage service designed for online backup and archiving of data and applications on Amazon Web Services. Amazon S3 was designed with a minimal feature set and created to make web-scale computing easier for developers.
AWS S3 is a key-value store, one of the major categories of NoSQL databases used for accumulating voluminous, mutating, unstructured, or semistructured data. S3 is capable of storing diverse and generally unstructured data, but it's also suited for hierarchical data and all kinds of structured information.
To check whether an object is encrypted or not you can use lambda. Using S3 client from boto3 get all object keys and then on object call the key. server_side_encryption. This will return AES256, aws:kms or none dependning upon the encryption.
The objects are encrypted using server-side encryption with either Amazon S3-managed keys (SSE-S3) or customer master keys (CMKs) stored in AWS Key Management Service (AWS KMS). When you use server-side encryption, Amazon S3 encrypts an object before saving it to disk and decrypts it when you download the objects.
All you need to do is enable server-side encryption in your object metadata when you upload your data to Amazon S3. As soon as your data reaches S3, it is encrypted and stored. Your data is always encrypted when it's stored in Amazon S3, with encryption keys managed by Amazon.
Within Amazon S3, Server Side Encryption (SSE) is the simplest data encryption option available. SSE encryption manages the heavy lifting of encryption on the AWS side, and falls into two types: SSE-S3 and SSE-C.
SSE-KMS (AWS managed CMK)
The only difference is that the secret key (aka AWS managed Customer Master Key (CMK)) is provided by the KMS service and not by S3. The S3 service is called from the same AWS account to encrypt/decrypt using the CMK. IAM in the same AWS account to use authorize read-only API actions.S3 encrypts the object with plaintext data key and deletes the key from memory. The encrypted object along with the encrypted data key is then stored in S3. While retrieving the object S3 sends the encrypted data key to KMS. S3 then retrieves the object by decrypting the object with this plaintext data key.
Server-side encryption protects data at rest. Amazon S3 encrypts each object with a unique key. Amazon S3 server-side encryption uses one of the strongest block ciphers available to encrypt your data, 256-bit Advanced Encryption Standard (AES-256).
Server-Side Encryption with Customer Master Keys (CMKs) Stored in AWS Key Management Service (SSE-KMS) is similar to SSE-S3, but with some additional benefits and charges for using this service. SSE-KMS also provides you with an audit trail that shows when your CMK was used and by whom.
Multipart Upload allows you to upload a single object as a set of parts. After all parts of your object are uploaded, Amazon S3 then presents the data as a single object. With this feature you can create parallel uploads, pause and resume an object upload, and begin uploads before you know the total object size.
Object storage
Amazon S3 is not a file system, it is an object store – it's a flat structure of objects and their containers (buckets). Again, AWS S3 has buckets of objects. There is no folder, subfolder or hierarchical structure.To optimize performance, we recommend that you access the bucket from Amazon EC2 instances in the same AWS Region when possible. This helps reduce network latency and data transfer costs. For more information about data transfer costs, see Amazon S3 Pricing .
Sign in to Amazon Web Services and go to your S3 Management Console. 2. Click on the name of the S3 bucket from the list. If it's still in its default access state, it should say “Buckets and objects not public” next to it.
A prefix list ID is required for creating an outbound security group rule that allows traffic from a VPC to access an AWS service through a gateway VPC endpoint. Currently, the services that support this action are Amazon S3 and Amazon DynamoDB. describe-prefix-lists is a paginated operation.
