Cloud Migration Strategy Guide | NorthBridge Technology

Executive Summary

Cloud migration has become a business imperative, with organizations worldwide moving workloads to cloud environments to increase agility, reduce costs, and enhance scalability. However, without a strategic approach, cloud migrations can lead to cost overruns, security vulnerabilities, and operational disruptions. This whitepaper outlines a comprehensive framework for planning and executing successful cloud migrations that maximize ROI while minimizing risks and business disruption.

NorthBridge Cloud Migration Framework

Our proven framework for cloud migration consists of five phases designed to ensure success while minimizing business disruption.

Phase 1: Assessment & Planning

Comprehensive evaluation of current environment, application dependencies, and business requirements to create a detailed migration strategy.

Phase 2: Design & Architecture

Design target cloud architecture, security controls, and operational processes aligned with business objectives and cloud best practices.

Phase 3: Proof of Concept

Validate migration approach with a pilot project, testing technical feasibility, performance, and operational processes before full-scale migration.

Phase 4: Migration Execution

Execute migration in waves using appropriate migration strategies, with continuous monitoring and rollback plans to minimize business impact.

Phase 5: Optimization & Operations

Optimize cloud environment for performance and cost, establish operational processes, and implement continuous improvement practices.

Cloud Migration Strategies

Selecting the right migration strategy for each workload is critical to success. We employ the AWS 6R framework, adapted for multi-cloud environments.

Rehost (Lift-and-Shift)

Moving applications without modification. Ideal for stable applications with minimal cloud optimization needs.

Best for: 40-50% of workloads

Replatform (Lift-Tinker-and-Shift)

Making minor optimizations to leverage cloud capabilities while maintaining core architecture.

Best for: 20-30% of workloads

Refactor / Rearchitect

Significantly modifying or completely rearchitecting applications to be cloud-native.

Best for: 10-15% of workloads

Repurchase

Moving to a different product, often switching to SaaS versions of applications.

Best for: 5-10% of workloads

Retire

Decommissioning applications that are no longer needed.

Identifies: 10-20% of applications

Retain

Keeping some applications on-premises, typically for compliance, latency, or dependency reasons.

Applies to: 5-10% of applications

Cloud Cost Management

Without proper cost management, cloud spending can quickly spiral out of control. Organizations waste significant amounts on cloud spend due to various inefficiencies.

Cost Management Challenges

Only 30% of organizations know where their cloud budget goes
41% cite lack of needed skills as biggest waste factor
Overprovisioning resources ranks as second biggest issue
Orphaned resources not being decommissioned

NorthBridge Cost Optimization

Implement cloud financial management practices

Right-size resources based on utilization metrics

Leverage auto-scaling and reserved instances

Establish tagging standards for cost allocation

Projected to save 21% on infrastructure spend

Security & Compliance

Cloud security is a shared responsibility between the provider and the customer. Misconfigurations remain the leading cause of cloud data breaches.

Security Risks

Misconfigured cloud storage and services
Average of 43 misconfigurations per cloud account
Inadequate identity and access management
95% of organizations concerned about cloud security posture
