This section of the Solution Architect Associate learning path introduces you to the core storage concepts and services relevant to the SAA-C03 exam. We start with an introduction to the 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
- 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 services available in AWS to optimize your storage
- Learn how to use AWS DataSync to move data between storage systems and AWS storage services
In this lecture I am going to answer the question, what is AWS DataSync? If you’ve been working with different AWS storage services for any length of time then you may have already come across this service. AWS DataSync is a service that allows you to easily and securely transfer data from your on-premise data center to AWS storage services. It can also be used to manage data transfer between 2 different AWS storage services too, so it’s a great service to help you migrate, manage, replace and move data between different storage locations.
At the time of writing this course, AWS DataSync supports the ability to work with data stored on Network File Systems shares, Server Message Block shares, and any self-managed object storage, in addition to the following AWS services:
- Amazon S3
- Amazon Elastic File System
- Amazon FSx for Windows File Server
- AWS Snowcone
When performing data transfer operations, whether this be from on-premises or between AWS storage services, DataSync support AWS VPC Endpoints and so its able to utilise the high bandwidth, low latency AWS network to it’s advantage, this helps to both simplify the management of the request and automate your data transfer across secure infrastructure. For more information on AWS Endpoints, please see our AWS Networking lecture found here: https://cloudacademy.com/course/aws-networking-features-essential-for-a-solutions-architect/vpc-endpoints/
With data transfer speed a being a key factor for a data transfer services, AWS Data Sync comes with its own purpose-built data transfer network protocol in addition to a parallel and multithreaded architecture to rapidly perform data transfer, this means that each DataSync task has the potential of utilizing 10 Gbps over a network link between your own on-prem data center and your AWS environment.
Obviously when working with data, especially when moving it between 2 points, security is a key concern. As a result AWS DataSync provides 2 levels that provide end-to-end security, these being encryption, in addition to data validation.
From an encryption perspective, encryption in transit is implemented by encrypting the data using the Transport Layer Security (TLS) protocol. When data reaches an AWS service, it also supports encryption at rest mechanisms that EFS and FSx for Windows service offers, in addition to the default encryption at rest option for Amazon S3.
The 2nd point, Data Validation, ensures that your data arrives at its destination in one piece, exactly as it was when it left the source ensuring that it wasn’t compromised or damaged in any way during its transit. This additional check helps to validate the consistency of your data that was written to the AWS storage service, and that its a perfect match from when it left its source location.
From a cost perspective, AWS DataSync usesa flat pricing strategy based on a per-gigabyte of data transferred, this makes it easy to predict avoiding any unexpected costs.
