Amazon S3

Commentaires: Before S3 we stored our sensitive files on hard drives where also our web application resides. One day it crashed and the files were gone. We started to use S3 and now our application does not depend on where is resides. We don't worry whether our storage is enough. I also use S3 to store my personal files. It is very cheap.

Avantages: Amazon S3 (Simple Storage Service) is an object storage service for the cloud. You can store any amount of data and access it anywhere in the world. You may stop depending on hard drives for your web applications and start using Amazon S3 to store your media files, log files etc. It provides 99.999999999% durability which means you may lose just one file in 10,000 years. S3 has versioning option which helps you to prevent accidential deletions. Lifecycle policies help you manage and automate the life of your objects in S3, keeping you from leaving your data unnecessarily available. For example, you can set a lifecycle for your log files to be automatically deleted after 30 days. You can host a static website easily and in a cost effective way without worrying about the underlying hardware.

Inconvénients: S3 has buckets to store objects and these buckets have universal names. So for example, you probably won't be able to open a bucket named "photos". Configuring security is a bit tricky. You have to be careful which buckets will be public and which will be private.

Commentaires: Amazon S3 helps to setup the industry level infrastructure with no big investment and do not require the long term commitment as we can buy the storage space on hourly wages. The different storage classes help us to remain within the budget.

Avantages: Amazon S3 is a simple cloud based object storage. The different storage classes are designed to manage the data as per the requirements of the objects. The Intelligent S3 Tiering upgrade or downgrade the storage class based on the access patterns of the object to enhance the availability and durability. The S3 cross region replication helps in replication of the S3 objects in other regions. The multi-factor authentication delete on S3 bucket is really a life saver feature to protect from accidental deletion of objects.

Inconvénients: Amazon S3 is not as simple as its name, the objects locks and versioning features are amazing but not easy as the learning curves sharp. The Storage monitoring provides limited number of notifications under the free tier.
