Overview
What Is Cloud Migration and Application Modernization?
A planned move of applications and data to the cloud, with a path to modernize them rather than simply relocating them.
The Need
- Ageing infrastructure that is costly to run and hard to change
- Applications that cannot scale with demand
- Data center contracts or hardware nearing renewal
The Approach
- Assess applications, dependencies and readiness
- Choose the right move for each workload: rehost, replatform or refactor
- Migrate in planned waves, with testing and rollback
Assumptions and Dependencies
- An inventory of applications and their dependencies
- Agreed priorities and business owners for each workload
- A target cloud environment with security and access in place

What It Includes
What the Solution Includes
The main elements and the role each plays. The exact scope is agreed for each engagement.
How It Works
How It Works
A staged approach, so each wave is tested before the next begins.
Assess
Review applications, dependencies, infrastructure and costs.
Design
Agree the target architecture, the move for each workload and the migration waves.
Deploy and Integrate
Prepare the target environment and migrate workloads wave by wave.
Validate
Test functionality, performance and security after each wave.
Operate and Improve
Optimize cost and performance, and continue modernization where agreed.

- Engagement model and ongoing support
Measuring Success
How to Measure Success
Example measures, not results achieved by Signisys. Agree a baseline, and keep targets separate from measured results.
Workloads Migrated
The share of planned workloads moved on schedule.
Migration Downtime
Service interruption during each migration wave.
Run Cost
The cost of running each workload before and after migration.
Release Frequency
How often modernized applications can be updated.

FAQs
Frequently Asked Questions
Common questions about cloud migration and modernization.
What business problem does this solution address?
Infrastructure and applications that are costly, hard to change or unable to scale, and the risk of moving them without a plan.
How does the solution work?
It assesses each workload, chooses how to move it, migrates in tested waves and modernizes applications where that adds value.
Which environments can it support?
On-premises and hosted environments moving to public, hybrid or multi-cloud.
What prerequisites should we assess?
Your application inventory and dependencies, data volumes, downtime windows, licensing and security requirements.
Which services are available to implement it?
Cloud Computing and Platform Engineering, covering assessment, implementation and ongoing improvement where agreed.
How do we know it is working?
Agree a baseline for measures such as workloads migrated, migration downtime, run cost and release frequency, and track them over time.
