In this third blog will go through Domain 2 in the exam guide

Domain 2: Implementation of SAP workloads on AWS

Different supported deployments of SAP on AWS

1. SAP on AWS
2. SAP RISE on AWS
3. SAP Business Technology Platform (BTP)
   This part of exam guide focuses on SAP on AWS deployment types. if you’re doing manual installation, you’ll need to take care of all best practices and prerequisites, which can be challenging.
   The preferred deployment for AWS is to use launch wizard for sap workloads, where wizard take care of all the steps and deploys a production certified solution in a few steps. Different supported software products are SAP HANA database and NetWeaver stack on SAP HANA database.

2.1 Deploy databases for SAP workloads on AWS.

• Administration of operating systems (for example, Linux, Windows)
  • SAP database operating systems licenses can be one of three (BYOL – AWS Market place – On-demand i.e. license included )
  • SAP HANA Environment Setup on AWS
  • Operating System and Storage Configuration
• File system layout of databases
  • storage IOPs and throughput requirements can be met by striping different EBS volumes from OS level
  • GP3 is 20% lower than gp2 cost per GB
  • Storage Configuration for SAP HANA
  • SAP HANA on AWS: High Availability Configuration Guide for SLES and RHEL
• AWS network concepts
  • SAP on AWS High Availability with Overlay IP Address Routing
  • Internet access for SAP support (SAProuter)
• Database administration and security
  • Patching operating systems and SAP with AWS Systems Manager
  • Backup using AWS Backint Agent to AWS S3

2.2 Deploy SAP applications on AWS

• Administration of operating systems (for example, Linux, Windows)
  • SAP BusinessObjects Business Intelligence Platform on AWS Deployment and Operations Guide for Linux
  • SAP NetWeaver Environment Setup for Linux on AWS
  • SAP NetWeaver on AWS Deployment and Operations Guide for Windows
• File system layout of SAP applications
  • Storage options are explained in domain 1.3 -> Certified block storage solutions for SAP
  • SAP NetWeaver Linux Disk Layout
  • SAP NetWeaver Windows Disk Layout
  • SAP Best Practice 14.1 – Create mount points and volume associations to align with function
• AWS network concepts
  • VPC concepts and subnetting options in domain 1.1, Also Internet Gateways, VPNs, and VPC endpoint configuration as needed.
• SAP Basis and SAP security
  • Network security in building SGs, NACLs
  • Access control using IAM
  • SAP Lens for Security Well-Architected Framework

2.3 Configure high availability for SAP workloads.

• AWS global infrastructure
• Administration of operating systems and databases
• SAP certified high-availability solutions on AWS
  • SAP HANA on AWS: High Availability Configuration Guide for SLES and RHEL
  • General SAP Architecture guidelines and decisions
• AWS networking concepts (for example, Amazon Route 53, overlay IP addresses, routing methods)
• High-availability cluster concepts

2.4 Configure the disaster recovery setup for SAP workloads.

• AWS global infrastructure
  • AWS Global Infrastructure
• Administration of operating systems and databases
  • Configuring database replication (SAP HSR)
• AWS networking concepts (for example, Route 53, routing methods)
  • High Availability of SAP Launchpad Service with Amazon Route 53
  • SAP on AWS High Availability with Overlay IP Address Routing
• RTO and RPO
  • Cloudwhales blog on how to achieve BC in the cloud
• Disaster recovery scenarios (for example, backup and restore, pilot light, warm standby, multi-site)
  • High Availability and Disaster Recovery Options for SAP HANA on AWS
  • Disaster recovery solutions on AWS

2.5 Automate deployments of SAP workloads.

• Infrastructure as code (IaC) (for example, AWS CloudFormation)
  • Use AWS CloudFormation templates (YAML or JSON) to deploy and manage deployments i.e. Stack (A collection of resources managed as a single unit)
  • Deploy SAP NetWeaver on the AWS Cloud with Quick Start
  • SAP HANA Quick Start
  • another option to use AWS Cloud Development Kit
• Configuration management tools (for example, AWS Systems Manager)
  • Use System Manager to install software (for example backint)
  • Use Systems Manager to patch and keep SAP systems updated
• AWS Launch Wizard for SAP
  • – AWS Launch Wizard for SAP
  • The two software now available to use with launch wizard is SAP HANA Database only and SAP NetWeaver on HANA Database.
  • Supported deployment models
    • Production and non-production
    • different OS types
    • Deploy SAP in a single VPC or across multiple VPCs
• DevOps tools
  • DevOps for ABAP development on SAP
  • DevOps for ABAP development on SAP
  • DevOps for Cloud Foundry on SAP BTP

2.6 Validate AWS infrastructure for hosting SAP workloads.

• Administration of operating systems (for example, Linux, Windows)
  • Performing tests with the HANA Hardware and Cloud Measurement Tools (HCMT)
  • Reviewing instance families and sizes
  • Validating dedicated hardware solution benefits (for example, SAP certified Nitro based EC2 instance)
  • Performing license checks for infrastructure for SAP workloads on AWS
• Database file system layout
• AWS network concepts
• Database administration and security
• Performance baseline for SAP
  • Performing storage checks by using the flexible I/O tester (FIO) and the dd command
  • Performing network latency tests
  • Validating infrastructure (for example, Well-Architected Review, SAP OSS Notes, certified operating systems, relational database management system combinations)
