[For AWS beginners] Easy to understand! What is Amazon S3?

Hello!
This is Inoue, a Persian cat from Beyond Shikoku Office.

I would like to give you a quick explanation S3 ], which is one of the Amazon Web Services

What is storage service [S3]?

S3 is an abbreviation for " Simple Storage Service ".
A cloud-based intelligent object storage service .
In other words, it's like a rental warehouse for storing data in the clouds.
Files (text and images) called objects are saved in containers called buckets.
Since data can be retrieved in object units, data can be stored flexibly as needed.

■S3 overview

1. Static website hosting (can be easily turned into a web server)
2. S3 Select (Query function allows you to easily aggregate S3 data)
3. You can easily scale up and scale down.

■Features of S3

1. Scalability
2. Availability/durability
3. reliability
4. Rich management functions
5. intelligent features

■Explanation of the features of S3
① Since it is an object storage, it is easy to scale up and down.
Multiple storage classes are available depending on the usage situation, and
lifecycle policies can be used to automatically migrate.
it can be scaled up or down depending on usage conditions,
and there is no need to worry about capacity limits.
②It claims data durability of 99.999999999% (eleven nines) and is strong against threats such as failures and errors.
S3 objects are automatically replicated and stored in at least three Availability Zones.
Therefore, even if one of them fails, you can continue using it.
③ It has encryption functions and access management tools to protect data from attacks.
④ Various management functions such as storage class analysis and life cycle policy are available.
Using the management function, you can select a storage class that fits your actual usage.
⑤ There is a function or service that executes data queries.

Also, the amount of data that can be stored is unlimited.
There is a limit of 5TB for one file, but it
is rare to frequently access data larger than 5TB, so there is no need to worry about the 5TB limit.

■S3 pricing system
There are five conditions under which charges will be incurred:

1. storage
2. Request and data retrieval
3. data transfer
4. Management and analysis
5. replication

What is a storage class?

Storage class refers
to the type of storage S3 offers a variety of storage types that you can rent.
Storage class can be changed depending on the situation.
You can change the storage class manually, but you can also change it automatically by setting a lifecycle policy.

summary

S3 is like a rental warehouse for storing data in the cloud, so
if you store data in a conveniently located rental warehouse, you can retrieve the data immediately, but
since it is in a good location, it is difficult to store it. However, it is costly.
When storing data in a rental warehouse in a faraway location like Glacier,
the location is poor, so it can be stored at a low cost.
However, since the rental warehouse is far away, it takes time and effort (cost) to retrieve the items.
With this in mind, it seems possible to decide on the storage class that is suitable for your operation.

This time, I gave a rough explanation of [S3], but
I would like to learn more about AWS and write another blog.

Growing every day, moving forward every day.
I have to update myself every day! ! !
Thank you for reading to the end.
