In this section of the AWS Certified: SAP on AWS Specialty learning path, we introduce you to the various Storage services currently available in AWS that are relevant to the PAS-C01 exam.
Learning Objectives
- Identify and describe the various Storage services available in AWS
- Understand how AWS Storage services can assist with large-scale data storage, migration, and transfer both into and out of AWS
- Describe hybrid cloud storage services and on-premises data backup solutions using AWS Storage services
- Identify storage options for SAP workloads on AWS
Prerequisites
The AWS Certified: SAP on AWS Specialty certification has been designed for anyone who has experience managing and operating SAP workloads. Ideally you’ll also have some exposure to the design and implementation of SAP workloads on AWS, including migrating these workloads from on-premises environments. Many exam questions will require a solutions architect level of knowledge for many AWS services, including AWS Storage services. All of the AWS Cloud concepts introduced in this course will be explained and reinforced from the ground up.
Hello and welcome to this short lecture, which will provide a high-level overview of how you can import on-premise data into EFS. If you're looking to use EFS, then it's likely that you already have a dataset in mind that you think would be better served using this service. For example, your home directories for your employees that might be served on local file servers on-premises. So how would you go about moving this data into EFS to use the benefits that it offers?
The recommended course of action is to use another service called AWS DataSync. This service is specifically designed to help you securely move and migrate and synchronize data for your existing on-premises site into AWS Storage Services such as Amazon EFS or Amazon S3 with simplicity and ease. The data transfer can either be accomplished over a direct connect link or over the internet. To sync source files from your on-premises environment, you must download the DataSync agent as a VMware ESXi to your site. The agent is configured with the source and destination target and associated with your AWS account, and logically sits in between your on-premise file system and your EFS file system.
DataSync is also very useful if you want to transfer files between EFS file systems either within the same AWS account or cross-account and owned by a third-party. To help with the management and implementation of this transfer, AWS has created an AWS DataSync in-cloud quick start and scheduler, which can be found here on GitHub.
Within the overview documentation of this tool, the following use cases are provided. You can migrate an NFS file system from Amazon EC2 to Amazon EFS within the same AWS region. Replicate an NFS file system from Amazon EC2 in one AWS region to an Amazon EFS file system in a different AWS region for disaster recovery. You can migrate an Amazon EFS file system from EFS standard with no lifecycle management to an EFS file system with lifecycle management enabled.
File systems with lifecycle management enabled will automatically move to a lower-cost Infrequent Access storage class based on a predefined lifecycle policy. You can migrate an Amazon EFS file system from one performance mode to another performance mode within the same AWS region, and replicate an Amazon EFS file system from one AWS region to another Amazon EFS file system in a different AWS region for disaster recovery. The configuration and implementation of the AWS DataSync tool is out of scope of this course. However, you can find more information on this service here.
That brings me to the end of this lecture.
