What is Amazon S3?

Amazon Simple Storage Service or commonly called Amazon S3 or S3 " plain " is a simple object storage service. The objects are stored in "buckets" that if we extrapolate it, it would become a folder (which it is not). We have to imagine it as the containers of the ships and inside it full of objects of different sizes, colors, shapes ...

It also uses the same Amazon infrastructure .. (yes the store).

Its main use is data storage, but later they incorporated new functionalities, such as the possibility of using it as a static web server.

characteristics

One of the first specifications that Amazon S3 has is its simplicity of use, "it serves what it serves", storing information at different levels of access and availability, and they are the market leaders in terms of some of its characteristics.

Performance
Speed of access to your data, with multiple simultaneous connections.

Scalability
Increases and decreases storage resources, depending on business needs.

Availability
Data always available at any time, day, week, month, year. Forget about having to administer an SLA.

Durability
Offers a data integrity of 99.999999999999% (11 nines), you make sure your data is safe.



Storage classes

S3 Standard
High durability, availability, and performance storage for high-frequency access data.

Its use, from static websites, to big data.

S3 Smart
Class that has the ability to change the type of storage of objects as needed, to save costs but without impacting the performance of the application.

Standard S3 - Infrequent access
Data storage infrequent but with fast access, processing and low latency than the standard Amazon S3. Ideal for backups and disaster recovery files.

S3 One Zone - Infrequent Access
Storage 20% cheaper than standard Amazon S3, for infrequent access but quick access when required. It is only stored in one geographic area as opposed to the 3 used by the standard Amazon S3.

Its typical use, for data that can be easily recreated. Thumbs, from images of a web administrator (CMS).

S3 Glacier
Low-cost storage for data archiving, for example logs.

S3 Glacier Deep Archive
New class of storage coming soon. Amazon S3 Glacier Deep Archive is the cheapest way to store on Amazon S3, optimized for
very long-term storage data, such as 7-10 years. Useful for complying with regulations for companies in the health or financial sector and for backups.



How do we use it?

At Dreams, we use Amazon S3 in different storage classes for the different projects that we have developed, in the different environments (DEV, PRE, QA, PROD ..).

The main use is common in the industry, backups, and data dump from different sources. (Infrequent data storage, and dynamic classes)

Another use we give it, as a static web server, we have several projects that compile everything dynamic into static that is later “deployed” against Amazon S3 and served with Amazon CloudFront (CDN). (Standard data storage)

Also to save configuration files and preferences, which is accessed on certain occasions and must be available in all infrastructures. (Infrequent access).
