Cloud Readiness Assessment: What It Is, What It Covers, What It Costs

What Is a Cloud Readiness Assessment?

A Cloud Readiness Assessment is not a one-time checklist or a standardised questionnaire. It is a multi-dimensional analysis that evaluates your organisation across six perspectives — aligned with the AWS Cloud Adoption Framework (CAF):

Business Perspective

Strategic objectives, business case, prioritisation criteria for migration, executive sponsorship, and governance structures.

People Perspective

Cloud competency in the team, training needs, change management capability, organisational structure, and role clarity.

Governance Perspective

Cloud governance framework, compliance requirements (GDPR, BSI, NIS2), risk management, audit capability, and reporting structures.

Platform Perspective

Infrastructure architecture, network design, existing cloud workloads, technology stack, dependencies, and integrations.

Security Perspective

Identity management, data protection, threat models, security automation, and incident response capability.

Operations Perspective

Monitoring, automation, operating model, SLAs, incident management, and DevOps maturity.

The result is not a technical document for architects, but a management-ready readiness report with clear traffic-light ratings, recommendations, and a prioritised migration plan.

What Does a Full Cloud Readiness Assessment Cover?

A professional Cloud Readiness Assessment at Storm Reply consists of four integrated modules:

Module 1: Discovery and Inventory

The process starts with automated capture of your IT footprint. The AWS Application Discovery Service (agent-based or agentless) captures servers, dependencies, performance data, and network connections — without manual inventories. This is supplemented by structured interviews with application owners, architects, and operations teams.

Module 2: Application Portfolio Analysis (7R Classification)

Each application is evaluated by:

1. Business criticality (from support systems to mission critical)
2. Technical complexity (dependencies, database types, integrations)
3. Licence and lifecycle status (end of support, vendor lock-in)
4. Migration strategy per the 7R Framework

The result is a complete application portfolio with migration strategy per application, effort estimate, and recommended position in the migration roadmap.

Module 3: TCO Analysis with AWS Migration Evaluator

The AWS Migration Evaluator analyses your current infrastructure costs and projects cloud costs post-migration — including compute, storage, network, managed services, and licence optimisation. Typical findings show 20–40% TCO reduction over three years, depending on current hardware age and utilisation levels.

Module 4: Migration Roadmap and MAP Application

Results from the first three modules produce a prioritised migration roadmap with migration waves, milestones, resource requirements, and business case. Storm Reply simultaneously manages the AWS MAP application process, so assessment results can be used directly as MAP evidence.

How Long Does a Cloud Readiness Assessment Take?

Duration depends primarily on three factors: number of applications to analyse, availability of subject matter experts on the client side, and completeness of existing inventory data. Storm Reply uses automation (AWS Application Discovery Service, Migration Evaluator) to accelerate discovery phases.

What Does a Cloud Readiness Assessment Cost?

Costs for a Cloud Readiness Assessment vary significantly — depending on scope, application count, and desired level of detail. Rather than specific day rates (which depend on project size and industry context), the decisive cost perspective is: what does an assessment cost compared to a misdirected migration?

Cost-Reducing Factors

AWS MAP Funding (Migration Acceleration Program)

As an AWS Premier Consulting Partner, Storm Reply can apply for MAP funding for qualified clients. MAP provides financial support for the Assess phase — a significant portion of assessment costs is thereby covered by AWS. Contact Storm Reply to check your MAP eligibility.

Automated Discovery

The AWS Application Discovery Service replaces manual inventories, significantly reducing runtime and therefore consulting effort — particularly for large application landscapes.

Phased Approach

A Cloud Screening as an entry point costs a fraction of a full assessment but provides sufficient data for an initial go/no-go decision and prioritises where deeper assessment creates the most value.

The ROI of an Assessment

A thorough assessment typically identifies 20–30% of applications as Retire candidates — systems that can be decommissioned and require zero migration effort. A further 15–20% are identified as Retain candidates that stay on-premises for now. This reduces actual migration scope by 35–50% compared to the initial "migrate everything to cloud" approach. The savings regularly exceed assessment costs by a large margin.

What Does a Cloud Readiness Assessment Concretely Deliver?

At the end of a professional assessment with Storm Reply, you receive the following deliverables:

1. Cloud Maturity Score: Assessment of your organisation on a multi-level maturity scale (Ad-hoc to Optimised) across all six CAF perspectives — presented as a radar chart with industry benchmark comparison.
2. Application Portfolio Report: Complete 7R classification of all analysed applications with effort estimate, dependency map, and migration priority.
3. TCO Comparison: Three-year cost projection on-premises vs. AWS, produced with AWS Migration Evaluator, with scenarios for various Reserved Instance options and Savings Plans.
4. Migration Roadmap: Prioritised wave plan with migration waves, milestones, resource requirements, and recommended AWS services per application group.
5. Compliance Gap Analysis: Identified compliance gaps (GDPR, BSI, NIS2) with concrete remediation steps and AWS-native controls.
6. MAP Application Documentation: Complete documentation for the AWS MAP funding application (where applicable).

Frequently Asked Questions About Cloud Readiness Assessments

Can we run an assessment in parallel with ongoing operations?

Yes. A Cloud Readiness Assessment does not require system downtime or production interventions. The AWS Application Discovery Service typically runs agentlessly and non-invasively. Interviews with application owners are coordinated in block appointments to minimise operational disruption.

What happens after the assessment?

The assessment concludes with an Executive Readout session presenting findings and recommendations. Storm Reply can then accompany the Mobilize phase — landing zone, governance setup, pilot migrations. The assessment is deliberately structured to be usable as the basis for the MAP Mobilize application.

How many staff do we need to provide for the assessment?

Depending on scope, we need access to: an IT architect or CTO (for overall architecture), application owners (1–2 hours per application group), a CISO or security lead (for security review), and an IT operations manager (for operations assessment). Typically, 10–30 person-hours of client effort per assessment type should be planned.

Do we need an assessment if we already know what we want to migrate?

Even then an assessment is worthwhile — particularly for TCO validation, the MAP application, and compliance analysis. An assessment often uncovers additional applications missed in initial planning or identifies dependencies that affect the migration plan.
