AWS Storage Essentials

• In 1($), data is stored as files in a hierarchy.
• In 2($), data is stored in fixed-size blocks.
• In 3($), data is stored as objects in buckets

• 1($) in the cloud is analogous to direct-attached storage (DAS) or a storage area network (SAN). 
• 2($) systems are often supported with a network-attached storage (NAS) server. 

You have taken a backup from your EBS volume last night, and it was 10 GB.  You made some changes in some files, which size 2 GB.

The next snapshot to take will write 10 GB to Amazon S3.

To protect data, Amazon S3 automatically encrypts all objects on upload and applies server-side encryption with S3-managed keys as the base level of encryption for every bucket in Amazon S3 at no additional cost.

you're a developer and you plan to build out an application to transcode large media files like videos. You will be using an AWS Lambda function to perform the transcoding, but you need a place to store both the original media files and the transcoded media files. Due to regulations, you need to store these files for at least a year.

Which of the storage services below are more suitable?

You're an architect for an ecommerce company that wants to run their MySQL database on an EC2 instance. This database needs a storage layer to store their order and customer information. The database will frequently be accessed and updated, so the storage layer needs to respond quickly. It's important that the storage is fast and durable.

Which AWS storage service should you use? 

You have a web application that needs to write to disk in order to perform certain calculations. The application will store temporary data during the calculation. The most important aspects of this architecture are speed and cost.

which storage solution would you choose? 

You're creating a WordPress site on multiple instances. By default, WordPress stores user uploads on the local file system. Since you want to use multiple instances, you will need to move the WordPress installation and all of the user customizations into a shared storage platform. Which storage option would you use? 

• 1($) is the raw storage capacity you purchase.  This is what you pay for and what is needed to calculate the operating costs and data center requirements.
• 2($) is the reduced capacity after allocating part of the raw capacity to system's operations (e.g. formatting and operating system, hardware failure protection overhead).
• 3($) is the available capacity from the formatted capacity after accounting for data protection services, such as snapshots, and space performance overhead.
• 4($) The actual capacity that you need for your data.

Your organization is running compute-intensive workloads that require high throughput, low-latency file access, and parallel processing for applications such as machine learning and high-performance computing (HPC). Which Amazon FSx file system is the best choice?
