AWS Migration Methodology

Modernizing IT: Gartner’s 5 Rs

Packaged

Apps

Databases

Custom Apps

Phase out

unnecessary

applications

Leave data or

applications in

place and

extend via new

platform

Replace custom

applications with

modern,

packaged

offerings

Move

application and

data to new

platform without

modification

Create new

applications

AWS Migration Patterns: Path to the Cloud

Phased Migration Strategy

Cloud Assessment Phase

•Assess Costs

•Assess Architecture

•Document current inventory & workloads

•Assess Security

Proof of Concept Phase

•Learn AWS

•Build a pilot

•Build Support within the organization

Data Migration Phase

•Leverage different storage options

•Migrate

Application Migration Phase

•Lift & Shift Migration

•Hybrid Migration

Leverage the Cloud Phase

•Auto-scaling

•Automation

•Elasticity

•High Availability

Optimization Phase

•Utilization

•Monitoring

•Efficiency

•Performance

•Re-engineering

Phase Driven Approach to Cloud Migration

Phase Process Benefits

Cloud

Assessment

• Financial Assessment (TCO calculation)

• Security and Compliance Assessment

• Technical Assessment (Classify application

types)

• Identify the tools that can be reused and the

tools that need to be built

• Migrate licensed products

• Create a plan and measure success

• Business case for migration (Lower

TCO, faster time to market, higher

flexibility & agility, scalability +

elasticity)

• Identify gaps between your current

traditional legacy architecture and

next -generation cloud architecture

Proof of

Concept

• Get your feet wet with AWS

• Build a pilot and validate the technology

• Test existing software in the cloud

• Build confidence with various AWS

services

• Mitigate risk by validating critical

pieces of your proposed architecture

Data

Migration

• Understand different storage options in the

AWS cloud

• Migrate fileservers to Amazon S3

• Migrate RDBMS to EC2 + EBS, or Amazon

RDS

• Redundancy, Durable Storage,

Elastic Scalable Storage

• Automated Management Backup

Phase Driven Approach to Cloud Migration

Phase Process Benefits

Application

Migration

• Understanding the different instance type and

performance characteristics

• Network connectivity and security controls

• Deploy instances and software

• Failure tolerance, optimal capacity

provisioning, high availability

• Scalable compute resources

• Infrastructure automation

Leverage the

Cloud

• Leverage other AWS services

• Automate elasticity and SDLC

• Flexibility and agility

• Automation and improved productivity

• Harden security

• Create dashboard to manage AWS resources

• Leverage multiple availability zones

• Reduction in CapEx in IT

• Flexibility and agility

• Automation and improved

productivity

• Higher Availability

Optimization • Optimize usage based on demand

• Improve efficiency

• Implement advanced monitoring and

telemetry

• Re-engineer your application

• Decompose your relational databases

• Increased utilization and

transformational impact in OpEx

• Better visibility through advanced

monitoring and telemetry

Phase Deep-Dive: Assessment & Discovery

Application/Device MappingA document that relates individual compute instances and

infrastructure to a specific application.

Security You will want to understand any application specific security

requirements, Data Protection mechanisms, authentication

mechanisms and security classification efforts.

Application Architecture DiagramsApplication diagrams that show the relationships between

infrastructure and software for a specific workload.

ComplianceAny compliance regulations will need to ne vetted in order to

meet the organizations audit requirements such as HIPPA,

PCI, DSS, FedRAMP

Integration/Dependency MappingA document that shows the integration points or

dependencies of one application on other applications.

Criticality, RPO/RTO ObjectivesWhat are the application specific criticality rankings,

RPO/RTO objectives and migration efforts will need to

consider application maintenance windows (Recovery Time

Objectives)

Application Load MetricsUnderstanding an applications load profile will help

understand the scale of the infrastructure required to support

the environment.

The Principles of Security Don’t Change Much

• Roles Based Access Control and Least Privilege Apply

• Use Security Groups to filter traffic

Remember You Are Always Working Remote

Deploying a bastion host in each Availability Zone can provide

highly available and secure remote access over the Internet

• Clients can use the Remote Desktop Protocol (RDP) over

HTTPS to establish a secure, encrypted connection

• Bastion hosts can run Windows PowerShell Web Access for

remote command line administration

SQL Server on AWS

SQL Server on Amazon EC2

• You Manage Your Infrastructure

• Advanced Deployments: WSFC +

Amazon RDS for SQL Server

• Fully Managed by AWS

• No Administrative Intervention

• Uses SQL Server Mirroring
