15 - S3 storage classes (AWS Certified Cloud Practitioner CLF02)

Summary

In this video, Ahmed El-Fakharany explains AWS S3 Storage Classes, focusing on their types, pricing, and ideal use cases. He covers the default S3 Standard class, its high availability and higher cost, and contrasts it with the more affordable S3 Standard-IA for infrequent access. He also introduces S3 One Zone-IA for secondary backups, Intelligent Tiering for flexible cost management, and other specialized options. The video emphasizes how AWS provides users with flexibility in choosing the right storage class based on data access needs and cost considerations, essential knowledge for cloud professionals preparing for AWS certification.

Takeaways

• 😀 S3 Standard is ideal for frequently accessed data with high availability (99.99%).
• 😀 S3 Standard-IA (Infrequent Access) is best for data that is accessed less often but needs quick retrieval when needed.
• 😀 S3 One Zone-IA offers a lower-cost solution for infrequent access data stored in a single availability zone.
• 😀 S3 Intelligent-Tiering automatically moves data between two access tiers based on access patterns to optimize storage costs.
• 😀 The S3 Standard class provides the fastest retrieval speed and is the most expensive in terms of storage costs.
• 😀 S3 Standard-IA is cost-effective for data that is accessed rarely, with retrieval costs higher than the Standard class.
• 😀 S3 One Zone-IA offers a 99.5% availability but is cheaper than other S3 classes, suitable for secondary backup data.
• 😀 S3 Intelligent-Tiering allows AWS to manage your data by shifting it to the appropriate storage class based on usage frequency, saving costs.
• 😀 When designing cloud storage solutions, it's important to understand the data's access frequency and storage needs before selecting the storage class.
• 😀 AWS S3 offers flexibility in cost and retrieval options, giving users control over how they manage and optimize their data storage strategies.
• 😀 Cost efficiency can be achieved by using the right storage class for the right data type (e.g., backups or logs) while balancing retrieval needs and availability.

Q & A

What is the main focus of the video?

The video focuses on explaining AWS S3 Storage Classes, including their differences, pricing, availability, and use cases.

What are AWS S3 Storage Classes?

AWS S3 Storage Classes are different levels of storage provided by AWS to manage data with varying access frequencies, durability, and costs.

What is the S3 Standard Storage Class used for?

The S3 Standard Storage Class is used for frequently accessed data that requires high availability and quick retrieval, such as user profile pictures.

How does the pricing of S3 Standard compare to other storage classes?

S3 Standard is the most expensive storage class because it provides the highest availability and fast retrieval of data.

What is the S3 Standard-IA (Infrequent Access) Storage Class?

S3 Standard-IA is used for data that is infrequently accessed but needs to be available when required. It is cheaper than S3 Standard but has a slightly reduced availability.

What does S3 One Zone-IA offer, and when should it be used?

S3 One Zone-IA offers lower-cost storage in a single availability zone. It is used for data that can tolerate being lost if the zone fails, such as secondary backups.

How does S3 Intelligent-Tiering work?

S3 Intelligent-Tiering automatically moves data between storage classes based on its access patterns, helping reduce costs while maintaining availability.

What was the purpose of the deprecated RRS (Reduced Redundancy Storage) class?

RRS was used for less critical data that didn't require the same level of redundancy. However, this class has now been deprecated and is no longer available.

What is the availability percentage of S3 One Zone-IA?

S3 One Zone-IA offers 99.5% availability, which is lower than the other storage classes due to its use of a single availability zone.

Why should you use Intelligent-Tiering, and how is it priced?

Intelligent-Tiering is useful for situations where you're unsure about data access patterns. AWS automatically adjusts storage based on usage. Pricing varies based on the frequency of access and how AWS moves data between tiers.
