Performance Factors Across AWS Storage Services
The course is part of this learning path
This section of the AWS Certified Solutions Architect - Professional learning path introduces you to the core storage concepts and services relevant to the SAP-C02 exam. We start with an introduction to AWS storage services, understand the options available, and learn how to select and apply AWS storage services to meet specific requirements.
- Obtain an in-depth understanding of Amazon S3 - Simple Storage Service
- Learn how to improve your security posture in S3
- Get both a theoretical and practical understanding of EFS
- Learn how to create an EFS file system, manage EFS security, and import data in EFS
- Learn about EC2 storage and Elastic Block Store
- Learn about the different performance factors associated with AWS storage services
Client-Side Encryption with Customer Provided Keys, CSEC. The encryption process is as follows. Using an AWS SDK, such as the Java client, it will randomly generate a plain text data key which is used to encrypt the object data. The customer provided CMK is then used to encrypt this client-generated data key. The encrypted object data and encrypted data key are then sent to S3. S3 will then store the encrypted object data and associate the encrypted data key as metadata of the encrypted object data. The decryption process is as follows. A request is made by the client to S3 to retrieve the object data. S3 sends both the encrypted object data and the encrypted data key back to the client. The customer-provided CMK is then used to decrypt the encrypted data key. The plain text data key is then used to decrypt the object data. You should now have a deeper understanding of the process of encryption and decryption for each of the encryption methods that S3 offers.
It is a simple process to apply encryption, but understanding what's happening behind the scenes, is essential from a security standpoint. Especially when you are responsible for maintaining the integrity of the data stored in S3. Many of us have seen and heard the news whereby large, international organizations have failed to apply either correct level of permissions, or, indeed, an encryption mechanism to customer data which has been accidentally exposed. Causing a detrimental effect to all organizations involved.
To accompany this course, I've also created an infographic which shows all five encryption options and this can be found using the link on screen. I have also added this URL within the transcript of this lecture.
