Description

** Not all content covered in the course introduction has been added to the course at this time. Additional content is scheduled to be added to this course in the future. **

In this section of the AWS Certified: SAP on AWS Specialty learning path, we introduce you to strategies for configuring high availability and disaster recovery for SAP workloads on AWS.

Learning Objectives

  • Understand how to configure high availability with Amazon RDS
  • Identify backup and disaster recovery strategies using the AWS Cloud
  • Describe various approaches for business continuity and diaster recovery 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. All of the AWS Cloud concepts introduced in this course will be explained and reinforced from the ground up.

Transcript

The Well-Architected Framework. The Well-Architected Framework is the document provided by AWS where best practices and lessons learned are documented for all customers to benefit from the collected know-how. It is organized around six pillars which focus on the ideas of Security, Reliability, Operational Excellence, Performance Efficiency, Cost Optimization, and Sustainability. There is a general overview document of all six pillars and a separate document focusing on each of these pillars individually. 

The goal of the Well-Architected Framework is to enable you to assess and improve your AWS architecture implementation by providing a catalog of questions around each of these pillars, where you can perform a discovery process and define fundamental issues that are often neglected in AWS implementations. The idea is to better understand the business impact of design decisions by evaluating your architecture using a consistent set of best practices. 

The framework is not about implementation details or architectural patterns, but it's a set of questions centered around helping you perform and understanding and gain clarity of your architectural decisions. The AWS services involved and finally, the references to consult for details. In a nutshell, the AWS Well-Architected Framework is a set of questions developed by AWS Experts to help you evaluate your architecture and in general ask, how does my infrastructure follow best practices with regards to the following six general categories? 

The categories are: 

Number 1, the Security pillar speaks to protecting your data and your systems. 

Number 2, the Performance Efficiency pillar speaks to using compute resources efficiently while minimizing over-provisioning as utilization fluctuates. The Cost Optimization pillar speaks to eliminating unneeded expenses. The Operational Excellence pillar speaks to running your workloads with enough automation and visibility to gain insights into day-to-day operations and be able to refine procedures. The Sustainability pillar speaks to energy consumption and environmental impact by directly acting on reducing your resource utilization. 

Last but not least, the Reliability pillar speaks to dynamically acquiring compute resources to meet demand. This is done using fleets of EC2 instances configured in an auto-scaling configuration according to your definitions for increasing and decreasing the size of the fleet. Reliability also speaks to Recovery from infrastructure or service failures by implementing enough redundancy, backup, restore, and recovery procedures. It is important to mitigate disruptions such as misconfigurations by using as much automation as possible. Our discussion will focus on backup and restore procedures for SAP on AWS as well as the different disaster recovery scenarios.
