Cloud Migration Services

Overview

Many organizations begin cloud migration due to infrastructure constraints, rising operational costs, slow delivery, or the need to scale globally. However, migrations fail when they are treated as purely technical tasks rather than business programs with risk, governance, and operational ownership.

A successful cloud migration delivers measurable outcomes: faster release cycles, reduced downtime, stronger security posture, predictable costs, and improved customer experience. We support cloud migrations to AWS and Azure and ensure your cloud environment is ready for long-term operations by integrating with cloud managed services and delivery enablement such as Azure DevOps services.

If your target platform is AWS, we align the migration approach with AWS cloud services including architecture design, security controls, and FinOps optimization.

What Cloud Migration Actually Includes

Cloud migration includes much more than copying workloads from on-premise to cloud. It typically involves application assessment, data migration planning, security and networking design, environment standardization, deployment automation, and operational transition. In practice, most organizations are migrating a portfolio of systems with dependencies, shared databases, integrations, and compliance constraints.

Our cloud migration program treats your migration like a delivery pipeline: repeatable, predictable, and scalable. We build a “migration factory” approach where patterns, templates, and runbooks are reused across workloads to reduce risk and accelerate delivery.

Key Service Areas

Scope

Our cloud migration services are modular and can be delivered end-to-end or in targeted phases depending on your cloud maturity and internal capabilities. Typical deliverables include:

• Discovery & Application Portfolio Assessment: workload inventory, dependency mapping, readiness scoring
• Migration Strategy: rehost, replatform, refactor, re-architect, retire, retain (6R/7R model)
• Target Architecture & Landing Zone: secure baseline networking, IAM, logging, tagging, policies
• Migration Execution: phased migration with rollback strategy and validation gates
• Data Migration: replication patterns, cutover planning, integrity validation
• Modernization: containerization, microservices, managed databases where it provides value
• DevOps Enablement: pipelines, deployment automation, release governance via CI/CD pipeline implementation
• Infrastructure as Code: repeatable provisioning via Infrastructure as Code services
• Container Adoption: Kubernetes migration and operationalization aligned with Kubernetes consulting services
• Post-Migration Stabilization: observability, performance tuning, incident readiness
• Operational Handover / Managed Ops: transition into cloud managed services

Typical timelines vary by scope. A “foundation + first wave” migration can be delivered in 4–8 weeks, while a broader enterprise portfolio migration typically spans 3–9 months depending on complexity, dependencies, and modernization requirements.

Approach

Our approach is designed to control risk and deliver results quickly. We focus on early wins while building reusable patterns that accelerate subsequent migration waves.

Phase 1: Assessment & Roadmap

We build an application inventory and map dependencies across services, databases, integrations, and network flows. Each workload is assessed for cloud readiness and categorized into a migration strategy. The output is a prioritized roadmap with migration waves, risk considerations, and expected benefits.

Phase 2: Landing Zone & Governance

Before migrating workloads, we build the cloud landing zone: network segmentation, IAM, logging, monitoring, tagging, policy baselines, and secure connectivity. This is the foundation that prevents future cost and security chaos.

Phase 3: Migration Factory Setup

We standardize tooling and create repeatable migration patterns and runbooks: templates for provisioning, standard deployment pipelines, and validation checklists. This reduces time per workload and improves quality.

Phase 4: Migration Execution (Waves)

We migrate in waves, starting with low-risk workloads to validate the approach, then moving to higher-criticality systems. Every migration wave includes cutover planning, rollback strategy, data validation, and post-migration testing.

Phase 5: Stabilization & Optimization

After cutover, we stabilize performance, implement monitoring dashboards, tune scaling rules, enforce security controls, and optimize cost. We then transition into long-term operations and improvement through cloud managed services.

Migration Strategies (The 6R/7R Model)

Not every workload should be refactored. We choose a strategy per application based on ROI, risk, and timelines:

• Rehost: quickest path—move as-is with minimal changes
• Replatform: small changes for better efficiency (e.g., managed DB)
• Refactor: significant code changes for cloud-native benefits
• Re-architect: redesign into modern architecture (microservices, event-driven)
• Retire: decommission systems with low value
• Retain: keep on-premise due to constraints
• Relocate: move VM clusters (common in certain enterprise setups)

Security, Compliance & Risk Management

Cloud migration introduces new security and governance requirements. We implement security-by-default and compliance readiness through IAM controls, encryption, network segmentation, logging and auditing baselines, and vulnerability management integration.

For enterprises with critical business platforms (ERP, integration middleware, financial systems), cloud migration is often tied to broader modernization initiatives and governance programs like SAP consulting services.

What You Gain After Migration

A successful cloud migration delivers real business outcomes:

• Higher availability and improved disaster recovery
• Faster releases through automation and standardized environments
• Elastic scaling for demand spikes without overprovisioning
• Improved security posture and auditability
• Cost transparency and optimization potential

Why Choose Global Technology Services

We migrate workloads with enterprise realism: dependencies, governance, compliance constraints, and operational ownership. Our priority is predictable delivery with controlled risk—not risky “big bang” migrations.

• Structured methodology: assessment → landing zone → migration factory → waves → stabilization
• Automation-first: CI/CD and IaC patterns built in from day one
• Security-by-default: IAM, logging, encryption, and governance baselines
• Operational transition: post-migration support via cloud managed services
• Flexible execution: project-based delivery or long-term acceleration via dedicated development team

FAQ

How long does a cloud migration take?

A first-wave migration can take 4–8 weeks, while enterprise portfolio migrations typically span 3–9 months depending on complexity, dependencies, and modernization requirements.

Should we refactor everything to cloud-native?

Not necessarily. We choose a strategy per application. Many workloads are rehosted or replatformed first, then modernized later when ROI justifies it.

What happens after migration?

After cutover, we stabilize the environment, implement monitoring and governance, and transition operations into cloud managed services for long-term reliability and optimization.

Can you migrate workloads to AWS?

Yes. We migrate to both AWS and Azure. For AWS migrations, we align the target architecture with AWS cloud services and implement security and cost controls.
