Migration and Innovation in the AWS Cloud

AWS Cloud Adoption Framework

The AWS Cloud Adoption Framework (AWS CAF) organizes guidance into six areas of focus, called Perspectives.

Focus on Business:

Business
People
Governance

Focus on Technical Capabilities:

Platform
Security
Operations

Business Perspective

The Business Perspective ensures that IT aligns with business needs and that IT investments link to key business results.

People Perspective

The People Perspective supports development of an organization-wide change management strategy for successful cloud adoption.

Governance Perspective

The Governance Perspective focuses on the skills and processes to align IT strategy with business strategy. This ensures that you maximize the business value and minimize risks.

Platform Perspective

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

Security Perspective

The Security Perspective ensures that the organization meets security objectives for visibility, auditability, control, and agility.

Operations Perspective

The Operations Perspective helps you to enable, run, use, operate, and recover IT workloads to the level agreed upon with your business stakeholders.

AWS CAF Use Cases

Use the Business Perspective to create a strong business case for cloud adoption and prioritize cloud adoption initiatives.
Use the People Perspective to evaluate organizational structures and roles, new skill and process requirements, and identify gaps.
Use the Governance Perspective to understand how to update the staff skills and processes necessary to ensure business governance in the cloud.
Use the Platform Perspective to understand and communicate the structure of IT systems and their relationships and describe the architecture of the target state environment in detail.
Use the Security Perspective to structure the selection and implementation of security controls that meet the organization’s needs.
Use the Operations Perspective to define how day-to-day, quarter-to-quarter, and year-to-year business is conducted.

Migration Strategies

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

Rehosting

Rehosting also known as “lift-and-shift” involves moving applications without changes.

Replatforming, also known as “lift, tinker, and shift,” involves making a few cloud optimizations to realize a tangible benefit. Optimization is achieved without changing the core architecture of the application.

Refactoring/re-architecting

Refactoring (also known as re-architecting) involves reimagining how an application is architected and developed by using cloud-native features. Now, you’re writing new code.

Repurchasing

Repurchasing involves moving from a traditional license to a software-as-a-service model. This is common for companies looking to abandon legacy software vendors. Repurchasing involves replacing an existing application with a cloud-based version

Retaining

Retaining consists of keeping applications that are critical for the business in the source environment. This might include applications that require major refactoring before they can be migrated, or, work that can be postponed until a later time.

Retiring

Retiring is the process of removing applications that are no longer needed.

AWS Snow Family

The AWS Snow Family is a collection of physical devices that help to physically transport up to exabytes of data into and out of AWS.

AWS Snow Family is composed of:

AWS Snowcone,
AWS Snowball, and
AWS Snowmobile.

example

AWS Snowcone

AWS Snowcone is a small, rugged, and secure edge computing and data transfer device.

It features 2 CPUs, 4 GB of memory, and 8 TB of usable storage.

AWS Snowball

AWS Snowball offers two types of devices:

Snowball Edge Storage Optimized devices are well suited for large-scale data migrations and recurring transfer workflows.
Snowball Edge Compute Optimized provides powerful computing resources for use cases such as machine learning, full motion video analysis, analytics, and local computing stacks.

Device	Storage	Compute
Snowball Edge Storage Optimized	80 TB HDD	40 vCPUs, 80 GiB of memory
Snowball Edge Compute Optimized	42 TB HDD	52 vCPUs, 208 GiB of memory

AWS Snowmobile

AWS Snowmobile is an exabyte-scale data transfer service used to move large amounts of data to AWS.

You can transfer up to 100 petabytes of data per Snowmobile.

AWS Snow Family Use Cases

AWS Snowcone - Customers usually use these devices to ship terabytes of information such as analytics data, video libraries, image collections, backups, and even tape replacement data.
AWS Snowball - The use cases include capturing of streams from IoT devices, image compression, video transcoding, and even industrial signaling.
AWS Snowmobile - It’s ideal for the largest migrations and even data center shutdowns.

Innovation with AWS

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.

Some of the paths you might explore:

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.

Example: AWS Lambda

Artificial Intelligence

AWS offers a variety of services powered by artificial intelligence (AI).

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

AWS offers Amazon SageMaker to remove the difficult work from the process and empower you to build, train, and deploy ML models quickly.

Notes

Common roles in the Business Perspective include: Business managers, Finance managers, Budget owners, Strategy stakeholders.
Common roles in the People Perspective include: Human resources, Staffing, People managers.
Common roles in the Governance Perspective include: Chief Information Officer (CIO), Program managers, Enterprise architects, Business analysts, Portfolio managers.
Common roles in the Platform Perspective include: Chief Technology Officer (CTO), IT managers, Solutions architects.
Common roles in the Security Perspective include: Chief Information Security Officer (CISO), IT security managers, IT security analysts.
Common roles in the Operations Perspective include: IT operations managers, IT support managers.
Edge computing options are Amazon EC2 instances and AWS IoT Greengrass.
Amazon Textract is a machine learning service that automatically extracts text and data from scanned documents.
AWS DeepRacer is an autonomous 1/18 scale race car that you can use to test reinforcement learning models.
The same VMware based infrastructure that you use on prem can be lifted up and dropped onto AWS via VMware Cloud on AWS.
