BTS of Amazon S3

  • In the previous article, we covered a high-level overview of Amazon S3.
  • We understood what exactly S3 is, why should one choose S3, and the top 3 features of Amazon S3.
  • Here, in this article, we will learn about the working of Amazon S3.
  • After that, we will learn how to build, train and deploy a machine learning model with the help of Amazon Sagemaker.
  • So as we know, Amazon Simple Storage Service (S3) is an object storage-based storage service that is massively scalable.
  • It has a very high level of durability, as well as high availability and performance.
  • Data can be accessed from anywhere in the world using the Internet using the Amazon Console, and the powerful S3 API.

Attributes of Amazon S3

  • Buckets: Data can be organized into buckets. Unstructured data can be stored in an infinite number of buckets.
  • Elastic scalability: S3 does not have a storage limit. Individual objects can have a maximum size of 5TB.
  • Flexible data structure: Each object is identified by a unique key, and metadata can be used to organize data in a variety of ways.
  • Downloading data: Data can be easily shared with anyone inside or outside your organization, and data can be downloaded via the Internet.
  • Permissions: To ensure that only authorized users can access data, assign permissions at the bucket or object level.
  • APIs: The S3 API, has become an industry standard and is integrated into a wide range of existing tools.

How Does S3 Storage Work?

  • Objects are used to store data in Amazon S3.
  • This method enables highly scalable cloud storage.
  • Objects can be stored on a wide range of physical disc drives located throughout the data center.
  • To provide true elastic scalability, Amazon data centers employ specialized hardware, software, and distributed file systems.
  • Amazon uses block storage methods to provide redundancy and version control.
  • The Amazon S3 service checks the integrity of the data on a regular basis by examining the control hash value.
  • If there is data corruption, redundant data is used to restore the object.

How to use Amazon S3?

  • The first step would be to create an Amazon S3 account.

  • The user can then build a bucket, add objects to the bucket, view objects, move objects, and delete objects and buckets.
  • Data is stored in Amazon S3 as objects in buckets.
  • An object is made up of a file and any metadata that pertains to that file.
  • To store an object in Amazon S3, the user must first upload the file to be stored in the bucket.
  • If we need to transmit a big amount of data, Amazon provides Import/Export, which allows us to upload and download data in S3.
  • A bucket with objects will be available on Amazon S3.
  • Because the bucket name is always a component of the URL, it should be unique across all Amazon accounts.
  • The concept of folders is also included in Amazon S3’s administration console.
  • A bucket cannot be contained within a bucket, although a folder can be contained within a bucket (grouping of multiple objects).
  • The public URL will be visible whenever a user submits an object.

Typical behaviors marked in S3

  • When a process writes an item to Amazon S3 and then tries to read it all at the same time.
  • Amazon S3 may report “key does not exist” before the update is fully propagated.
  • A procedure creates a new object in Amazon S3 and lists the keys in its bucket right away.
  • The object may not appear in the list until the modification is fully propagated.
  • A process substitutes an existing object and tries to read it right away.
  • Amazon S3 may return the previous data until the update is fully propagated.
  • A procedure deletes an existing object and then tries to read it right away.
  • Amazon S3 may return removed data until the deletion is fully propagated.
  • A process deletes an existing object and lists the keys within its bucket immediately.
  • Amazon S3 may list the removed object until the deletion is fully propagated.

S3 Functionality

  • The user can create, read, and delete objects ranging in size from one byte to five terabytes.
  • There is no limit to the number of things that can be saved.
  • A developer-assigned key can also be used to obtain the objects.
  • The authentication measures are in place to keep data secure against unauthorized access.
  • Objects can be made private or public, and certain users can be granted rights.
  • Uses REST and SOAP (https) interfaces that are meant to interact with any Internet-based toolkit.
  • The BitTorrent Protocol is also supported.
  • Reduced Redundancy Storage (S3) provides less durability at a cheaper cost.

Conclusion:

  • So far in this article, we covered a high-level overview of how does Amazon S3 works.
  • In the next article, we will learn about Amazon Sagemaker.
  • After that, we will learn how to build, train and deploy a machine learning model with the help of Amazon Sagemaker.
