Amazon Standard Storage
For data that are frequently accessed, such as logs for the last 24 hours or a media file that is being accessed frequently, Amazon Simple Storage offers affordable, highly available storage capacity that can grow as quickly as your organization needs.
Amazon Infrequent Access Storage
Using the S3 interface, monitor and manage resources that are necessary for your operation but are used far less frequently. By designating these buckets as infrequent access, data availability will be 99.9% (amounting to less than 9 hours of downtime in a year) as compared to 99.99% availability (less than an hour of downtime in a year) for standard storage but can be stored for far less cost per gigabyte than Standard Storage buckets.
For deep storage items that must be retained but are rarely used, Amazon Glacier provides long-term archiving solutions. Data stored in Glacier can take hours to retrieve instead of seconds, but the cost is a fraction of standard storage. With redundant data sites all over the world Glacier ensures your archival data is secure and safe no matter what happens.
Amazon Reduced Redundancy Storage
This service allows for the storing of non-essential, easily reproducible data, without the same amount of redundancy and durability as their higher-level storage tiers. Understanding these storage concepts in S3 is essential before building your cloud architecture. You can learn more about the intricacies of S3 here. Now let’s take a look at some of the other AWS services that can be used to build scalable cloud application.
