Cloud Migration to AWS, Azure, or GCP

The best cloud platform depends on your specific requirements, existing tech stack, and business goals. AWS offers the broadest service catalog and global reach. Azure integrates seamlessly with Microsoft technologies and hybrid cloud scenarios. GCP excels in data analytics, machine learning, and Kubernetes-based workloads. We conduct a thorough assessment of your needs, evaluate TCO across platforms, and recommend the optimal choice based on technical fit, cost efficiency, and long-term scalability requirements.

Lift & Shift (rehosting) involves moving applications to the cloud with minimal changes, offering faster migration and lower initial costs but limited cloud-native benefits. Re-Architecture (refactoring) redesigns applications to leverage cloud-native services like serverless, containers, and managed databases, providing better performance, scalability, and cost efficiency but requiring more time and investment. We evaluate each application and recommend the optimal approach based on business criticality, technical debt, and ROI potential.

Migration timelines vary significantly based on application complexity, data volume, and chosen strategy. Simple lift-and-shift migrations of small applications can complete in 4-6 weeks. Mid-sized migrations with moderate re-architecture typically take 3-6 months. Large-scale enterprise migrations involving dozens of applications and extensive re-platforming can take 12-18+ months. We provide detailed project timelines during the planning phase, with phased migration approaches that deliver incremental value while minimizing business disruption.

We design migrations to minimize or eliminate downtime through proven strategies including blue-green deployments, database replication, DNS cutover, and parallel run periods. For most applications, we achieve zero-downtime migrations by running old and new environments simultaneously and switching over during low-traffic periods. Critical applications may experience brief planned maintenance windows (typically 1-4 hours during off-peak times). We work closely with your team to schedule migrations around business requirements and implement rollback procedures for maximum safety.

Security is paramount throughout our migration process. We implement encryption in transit using TLS/SSL and encryption at rest for all data. Data transfers occur over secure VPN connections or direct connect links. Access controls follow least-privilege principles with multi-factor authentication required. All migration activities are logged and auditable. We conduct security assessments before and after migration, implement network segmentation, configure security groups and firewalls, and ensure compliance with relevant standards (SOC 2, HIPAA, PCI-DSS, GDPR) based on your industry requirements.

Cloud migration actually enhances disaster recovery capabilities. We design cloud architectures with multi-region redundancy, automated backups, and faster recovery times than traditional on-premises solutions. Your existing DR requirements inform our cloud architecture design, and we implement cloud-native DR solutions including automated snapshots, cross-region replication, and infrastructure-as-code for rapid recovery. We test all DR procedures thoroughly and provide updated runbooks and recovery documentation aligned with your cloud infrastructure.

Migration costs include one-time migration services and ongoing cloud operational costs. Migration services typically range from $50,000-$500,000+ depending on application count, complexity, and re-architecture requirements. Ongoing cloud costs vary based on usage but often decrease 20-40% compared to on-premises infrastructure when properly optimized. We provide detailed cost estimates during assessment, including TCO analysis comparing on-premises vs. cloud over 3-5 years. Our optimization services ensure you maximize cloud ROI by rightsizing resources, implementing reserved instances, and eliminating waste.

Absolutely! Hybrid cloud approaches are common and often recommended. We can migrate specific applications or workloads while keeping others on-premises based on technical constraints, compliance requirements, or business priorities. We design hybrid architectures with secure connectivity between cloud and on-premises environments, implement consistent management and monitoring across both, and create phased migration roadmaps that allow you to move incrementally as your team builds cloud capabilities and confidence.

Post-migration support includes immediate hypercare support (30-90 days of intensive monitoring and optimization), cloud operations training for your team, documentation including architecture diagrams and runbooks, cost optimization reviews and recommendations, performance monitoring and tuning, security posture reviews, and ongoing managed services if desired. We ensure your team is fully capable of managing the cloud environment independently or provide flexible managed services for continued operational excellence.

Legacy applications require special consideration and multiple approaches. Options include containerization to encapsulate dependencies and improve portability, refactoring specific components while maintaining core functionality, implementing API layers to enable cloud integration while keeping legacy backends, using cloud-based virtual machines that closely replicate on-premises environments, or maintaining hybrid architectures where legacy apps remain on-premises with cloud integration. We assess each legacy application individually and recommend the most cost-effective modernization path that balances technical feasibility, business value, and risk tolerance.
