AWS cloud Adaption Framework (AWS CAF)

Six core perspectives of the Cloud Adoption Framework

AWS CAF organizes guidance into six areas of focus, called Perspectives. Each Perspective addresses distinct responsibilities. The planning process helps the right people across the organization prepare for the changes ahead. These are:

1. Business
2. People
3. Governance Perspectives focus on business capabilities, 
4. Platform
5. Security
6. Operations  Perspectives focus on technical capabilities.

Question 1

Which Perspective of the AWS Cloud Adoption Framework helps you design, implement, and optimize your AWS infrastructure based on your business goals and perspectives?
The correct response option is Platform Perspective.

The Platform Perspective  includes principles for implementing new solutions and migrating on-premises workloads to the cloud.

Note:

Business Perspective helps you to move from a model that separates business and IT strategies into a business model that integrates IT strategy.

Operations Perspective focuses on operating and recovering IT workloads to meet the requirements of your business stakeholders.

People Perspective helps Human Resources (HR) employees prepare their teams for cloud adoption by updating organizational processes and staff skills to include cloud-based competencies.

6 Strategies for Migration  

When migrating applications to the cloud, six of the most common migration strategies that you can implement are:

1. Rehosting
2. Replatforming
• involves selectively optimizing aspects of an application to achieve benefits in the cloud without changing the core architecture of the application. 
• It is also known as “lift, tinker, and shift.”
3. Refactoring/re-architecting
• Changing how an application is architected and developed, 
• Typically by using cloud-native features.
4. Repurchasing  
• Move to a different product
• Replacing an existing application with a cloud-based version
5. Retaining
• 
  
6. Retiring
• Removing an application that is no longer used or that can be turned off.

Question 1
Which migration strategy involves moving to a different product?
Repurchasing.
Repurchasing involves replacing an existing application with a cloud-based version, such as software found in AWS Marketplace.

Note: 

Refactoring involves changing how an application is architected and developed, typically by using cloud-native features.

Retiring involves removing an application that is no longer used or that can be turned off.

Replatforming involves selectively optimizing aspects of an application to achieve benefits in the cloud without changing the core architecture of the application. It is also known as “lift, tinker, and shift.”

What is the storage capacity of Snowball Edge Storage Optimized?
The correct response option is 80 TB.
Snowball Edge Storage Optimized is a device that enables you to transfer large amounts of data into and out of AWS. It provides 80 TB of usable HDD storage.

- Innovation with AWS

- Innovate with AWS Services

When examining how to use AWS services, it is important to focus on the desired outcomes. You are properly equipped to drive innovation in the cloud if you can clearly articulate the following conditions: 

The current state

The desired state

The problems you are trying to solve

Consider some of the paths you might explore in the future as you continue on your cloud journey. 

Serverless Applications

With AWS, serverless refers to applications that don’t require you to provision, maintain, or administer servers. You don’t need to worry about fault tolerance or availability. AWS handles these capabilities for you.

AWS Lambda is an example of a service that you can use to run serverless applications. If you design your architecture to trigger Lambda functions to run your code, you can bypass the need to manage a fleet of servers.

Building your architecture with serverless applications enables your developers to focus on their core product instead of managing and operating servers.

Artificial Intelligence 

AWS offers a variety of services powered by artificial intelligence (AI). 
For example, you can perform the following tasks:

• Convert speech to text with Amazon Transcribe.
• Discover patterns in text with Amazon Comprehend.
• Identify potentially fraudulent online activities with Amazon Fraud Detector.
• Build voice and text chatbots with Amazon Lex.

Machine learning

Traditional machine learning (ML) development is complex, expensive, time consuming, and error prone. AWS offers Amazon SageMaker to remove the difficult work from the process and empower you to build, train, and deploy ML models quickly.

You can use ML to analyze data, solve complex problems, and predict outcomes before they happen.
