Description

In this section of the AWS Certified: SAP on AWS Specialty learning path, we introduce you to the various Compute services currently available in AWS that are relevant to the PAS-C01 exam.

Learning Objectives

  • Identify the various Compute services available in AWS
  • Define the different families within AWS Compute services
  • Identify the purpose of load balancers and Elastic Load Balancing
  • Understand how Auto Scaling can enable your Compute resources to scale elastically based on varying levels of demand
  • Identify supported EC2 instance types for SAP 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 Compute services. All of the AWS Cloud concepts introduced in this course will be explained and reinforced from the ground up.

Transcript

Migrating by using an AMI. If you're not able to resize your instance in place, you might also migrate over to a new instance by using an AMI. This is also a pretty simple endeavor that is very similar to the previous method. First, make sure you are running a supported operating system version. Upgrade your operating system if not. Again, the high memory instances are Nitro based where your EBS volumes are presented as NVME block devices. 

So, you'll have to create labels for those devices and mount to those labels. You'll need to make a backup of your source system. You'll need to stop the source instance. You can create an AMI of your source instance. Then we can launch a new High Memory EC2 instance using your AMI. Since the new instance will have a new IP address, you'll need to update all references to the old IP address to this new one. You might need to adjust the storage size of your SAP HANA data, log, shared, and backup volumes. Then you can start your SAP HANA database and perform validation. 

And finally, you'll need to complete any SAP HANA specific post migration activities, AWS post migration activities, and configure SAP HANA systems for High availability.
