What are S3 storage classes?

Amazon Simple Storage Service (S3) provides a powerful and flexible option for users needing to store and manage data in the cloud. With varying levels of access frequency, durability, and cost efficiency, S3 allows users to select from different storage classes tailored to their needs.

Most Suitable For:  Frequently accessed data

The S3 Standard class is considered the main choice and works best for data that is accessed often and needs to be stored reliably, while also having low waiting time. It provides the following:

• 99.999999999% durability
• 99.99% availability over a given year
• High throughput with low latency

Use S3 Standard when saving data for websites, apps, or real-time analytics, as it provides the best performance. Even though this is not the cheapest option, it can be used for business tasks that require timely data to be fetched.

Most Suitable For: Changing or unpredictable access patterns

The Intelligent-Tiering allows businesses to shift their data between the two levels of the hierarchy seamlessly depending on access patterns. This class works best for operations that require varying access levels on a day-to-day basis. It provides the following:

• 99.999999999% durability
• Low latency and high throughput
• Reduction of expenses through automation of data movement

Intelligent-tiering does come with a small expense as data monitoring and automation is required. However, by using this tier, businesses benefit from not needing to stress about where to allocate their data as ladder changes occur and therefore saving money.

Most Suitable For:  Data that is infrequently accessed but needs to be retrieved quickly when required.

This Tier S3 I normally goes best with data not frequently used but is often needed. You pay a lower storage cost compared to the S3 Standard, but you incur retrieval costs. Some of its features are as follows:

• 99.999999999% durability

• Lower cost for storage compared to Standard

• Retrieval costs apply

This class is ideal for infrequently accessed archived information set for retrievals in long-term computerized data restorations or disaster management recovery operations. They can also be used for for long term backups.

Most Suitable For: Data that is infrequently accessed but can be recreated if lost.

S3 One Zone-IA class offers savings over S3 IA while continuing to provide the same benefits. It does this by saving information in one zone only instead of the three available. If the information is not essential and can be recycled, this is the more economical path. It offers:

• 99.999999999% durability within a single availability zone

• Lower storage costs than S3 IA

• Data loss risk in case of a single zone failure

One Zone-IA is commendable for data not needed for day to day business purposes. But, it should be kept on margin for secondary information.

Most Suitable For: Archival information with retrieval time constraints.

Glacier provides long term data archival solutions. S3 glacier allows users to retrieve their data in a duration that ranges from minutes upto hours with much slower retrieval costs. It is also featured with the following:

• 99.999999999% durability
• Options for retrieval include bulk, expedite and standard. These options vary on the urgency of your request.
• Storage costs for users are almost negligble.

Glacier will be of utmost help for businesses with compliance tasks to manage or logging, backups and old records which are regarded as important but are not accessed frequently.

Most Suitable For: long term archiving with minimal access.

S3 Glacier Deep Archive is designed specifically for materials which require long term storage. This is similar to compliance but requires or sensitivity and is needed for archival purposes. It also provides the following:

  Most Suitable For: Keeping data within the company or using hybrid cloud services.

Outposts for S3 utilize the application programming interface (API) of S3, thus giving users the ability to save information and files locally. This is ideal for businesses that need to tightly control where their data is stored and accessed from or for those that work with dozens of large datasets. It is also useful for applications that have tight requirements on data from a specific region and need minimal delay when accessing data.

There are critical factors that should be regarded with respect to the selecting the storage class:

• Diminished Access interval: How frequently will the data be utilized?
• To Acquire Interval: How long will it take to access the data?
• Criticality: Is the data essential or important to the business?
• Estimated Budget: How much does the project cost?

Each S3 storage approach has its particular benefits, and knowing them will assist you save on expenses while ensuring that the resources are used efficiently.
