A Phased Driven approach to Cloud Migration

Includes:
Financial Assessment (TCO/ROI Analysis)
Security and Compliance Assessment
Technical Assessment
Choosing the right candidate
Migrating Licensed products
Identifying the tools that you can reuse
Functional/Architectural assessment

Security and Compliance Assessment
You own the data, not AWS.
You choose which geographic location to store the data. It doesn’t move unless you decide to move it.
You should consider the sensitivity of your data and decide if and how you will encrypt your data while it is in transit and while it is at rest.
Involve your Security Teams early in the process

Create a Dependency Tree of your IT Assets
Dashboard
Report
CRM
Search
DB
logs
Service
LDAP
Auth
Web
Engine
OLAP
ERP
List all your IT assets
Identify upward and downward dependencies
Start classifying your IT assetsinto different categories:
Applications with Top Secret, Secret, or Public data sets
Applications with low, medium and high compliance requirements
Applications that are internal-only, partner-only or customer-facing
Applications with low, medium and high coupling
Applications with strict, relaxed licensing

How to choose the right candidate for the cloud?
Dashboard
Report
CRM
Search
DB
logs
Service
LDAP
Auth
Web
Engine
OLAP
ERP
Search for under-utilized IT assets
Applications that has immediate business need to scale
Applications that are running out of capacity
Low-hanging fruits (Examples):
Web Applications
Batch Processing systems
Build/QA/Test systems
Content Management Systems
Digital Asset Management Systems

Includes:
Get your feet wet with Amazon Web Services
Learning AWS
Build reference architecture
Be aware of the security features
Build a Prototype/Pilot
Build support in your organization
Validate the technology
Test legacy software in the cloud
Perform benchmarks and set expectations

Get your feet wet – In the cloud in 5 minutes

Includes:
Learning about different database storage options available today
Uploading/Moving your data in Batches
Analyzing your database/datasets
Build necessary toolsand scripts to migrate data
Security of your data (Encryption)

Leverage different storage options in cloud

Includes:
Decide a strategy (Forklift/Hybrid)
Automate your processes by creating AMIs
Build “cloud-aware” layers of code for tightly coupled apps
