Cloud Migration Services We Deliver
From cloud readiness assessment and migration strategy through lift-and-shift rehost, application re-platforming, database migration, AWS/Azure/GCP environment setup, hybrid cloud, disaster recovery, cloud cost optimisation, and post-migration managed services.
Cloud Readiness Assessment & Migration Strategy
Structured assessment of your application portfolio — application inventory (infrastructure, dependencies, data volumes, integration points), 6R strategy assignment per application (rehost, replatform, repurchase, refactor, retire, or retain), business case and TCO analysis, migration wave planning, risk identification, and a detailed migration roadmap before any migration work begins.
Lift & Shift Cloud Migration (Rehost)
Migrate applications to cloud VMs as-is with no code changes — fastest path to cloud with minimal risk. We use AWS Server Migration Service, Azure Migrate, and VMware HCX for VM-based migrations, configure equivalent cloud networking and security groups, establish backup and monitoring, validate application functionality post-migration, and decommission source servers. Typical timelines: 1–3 weeks per application group.
Application Re-platforming & Modernisation
Migrate applications to cloud-managed services while preserving the application core — move from self-managed MySQL/PostgreSQL to RDS/Aurora, from on-premises app servers to ECS/EKS containers or Elastic Beanstalk, from Windows services to serverless Lambda functions, and from NFS file shares to EFS/Azure Files/GCS. Reduce operational overhead without rewriting application logic.
Database Migration to Cloud
End-to-end database migration — Oracle, SQL Server, MySQL, PostgreSQL, MariaDB, and MongoDB to AWS RDS, Aurora, Azure SQL Database, Azure Database for PostgreSQL/MySQL, or GCP Cloud SQL. Using AWS Database Migration Service, Azure Database Migration Service, or pg_dump/restore for smaller databases. Homologation testing for data integrity and stored procedure compatibility before cutover.

Our Cloud Migration Process
From discovery and readiness assessment through migration strategy, cloud landing zone setup, wave-by-wave application migration, database migration, and post-migration optimisation with hypercare support.
We begin with a comprehensive assessment of your application portfolio — documenting each application's architecture, dependencies (databases, APIs, messaging), data volumes, performance requirements, compliance constraints (GDPR, HIPAA, PCI-DSS, SOC 2), current infrastructure utilisation, and integration points. We interview application owners and operations teams. Output: a scored application inventory with recommended migration strategy (6R) per application, risk ratings, and dependency mapping.
We produce a migration strategy document covering: target cloud platform recommendation (AWS, Azure, GCP, or multi-cloud) with rationale, cost comparison (current on-premises TCO vs projected cloud TCO with optimisation), wave plan (prioritised migration groups — low-risk rehost applications first, complex refactor applications last), estimated timeline and resource requirements, risk register and mitigation plan, and success criteria for each migration wave.
Before migrating any application, we establish your cloud foundation — multi-account or subscription architecture (AWS Control Tower or Azure Landing Zones), VPC/VNet network topology, private connectivity (Direct Connect or ExpressRoute), DNS configuration, IAM/RBAC policies with least-privilege principles, centralised logging and security event collection, cost budgeting and tagging policies. All infrastructure is written in Terraform and version-controlled in Git.
Migration proceeds in waves — starting with a small pilot wave of 3–5 lower-risk applications to validate the migration process, tooling, and runbooks before scaling to larger waves. Each wave includes: pre-migration checklist, VM or application migration execution, database migration and validation, network connectivity testing, application functional testing, performance baseline comparison to on-premises, and cutover execution with rollback capability.
Database migrations are executed separately from application migrations to minimise risk — pre-migration schema validation, AWS DMS or Azure DMS continuous replication setup (for large databases), homologation testing (row counts, data integrity, stored procedure execution, query performance), parallel-run period with both source and target databases live and synchronised, and final cutover with minimal downtime (typically under 1 hour for DMS-based migrations).
After each wave goes live: cloud cost review and rightsizing, security posture review (public exposure audit, IAM permissions review), performance comparison to pre-migration baseline, monitoring and alerting validation, runbook documentation for common operational tasks, and knowledge transfer to your cloud operations team. We provide a 30-day hypercare period post-migration with heightened monitoring and rapid incident response.
What Our Cloud Migration Clients Say
Engineering and IT leadership teams across the US, UK, and Australia trust 1Solutions to plan and execute their cloud migrations — from single application moves to full data centre exit programmes.
1Solutions migrated our 40-application portfolio from an ageing VMware data centre to AWS in 9 months. They ran the full programme — assessment, wave planning, IaC with Terraform, rehost migrations, two re-platform projects (moving to RDS Aurora), and our Oracle database migration. Zero data loss, zero production outages. Our infrastructure bill dropped from $180K/month to $72K/month in year one.
We had 18 months to exit our on-premises data centre before the lease expired. 1Solutions delivered a 3-wave Azure migration covering 60 workloads — including our SQL Server databases to Azure SQL Managed Instance, our Windows Server applications to Azure VMs, and our file servers to Azure Files. They finished in 14 months with two months to spare. The Azure ExpressRoute connectivity and hybrid DNS setup they designed is rock solid.
1Solutions conducted our cloud readiness assessment and helped us avoid a $2M mistake. We were planning to lift-and-shift our entire monolith to EC2 instances and we would have had the same operational overhead with a cloud bill on top. They redesigned our approach — a targeted replatform of three components to serverless and ECS containers, with the rest staying on-premises until we refactor. We saved 18 months of wasted cloud spend.

Cloud-agnostic expertise across AWS, Azure, and GCP, assessment-first approach, wave-based migration delivery, zero data loss record, FinOps built in, security-first architecture, IaC for everything, and post-migration managed services available.
Cloud-Agnostic — AWS, Azure & GCP Certified
We are platform-agnostic and experienced across AWS, Microsoft Azure, and Google Cloud. We recommend the right cloud for your specific requirements — not the platform we prefer or are commercially incentivised to recommend. We hold AWS Solutions Architect, Azure Administrator, and GCP Professional Cloud Architect certifications on our team.
Assessment-First — No Migration Without a Plan
We never start migrating before we understand the full picture. Every engagement begins with a structured cloud readiness assessment — application inventory, dependency mapping, 6R strategy, risk assessment, cost modelling, and wave planning. The assessment prevents surprises mid-migration and ensures the business case is sound before commitment.
Wave-Based Migration — Value From Sprint One
We do not take a 12-month "big bang" approach to migration. We migrate in waves — prioritising low-risk, high-value applications in early waves to deliver quick wins and validate tooling before tackling complex workloads. You see applications running in cloud within weeks, not months.
Zero Data Loss Record
Database migration is the highest-risk element of any cloud migration. Our methodology — continuous DMS replication, parallel-run validation, data integrity checksums, stored procedure parity testing, and final cutover under 1 hour — has achieved zero data loss across all database migrations we have delivered. We do not cut corners on database validation.
FinOps Built In From Day One
Cloud migrations that do not plan for cost optimisation often result in cloud bills higher than the on-premises spend they replaced. We implement rightsizing, Reserved Instance planning, auto-scaling, storage tiering, and tagging from the start — our cloud migrations typically achieve 30–50% total infrastructure cost reduction compared to on-premises equivalents.
Security-First Cloud Architecture
Every cloud environment we build is security-first — least-privilege IAM, no public S3 buckets, encrypted storage and transit, CloudTrail/audit logging, Security Hub or Azure Defender, VPC security groups and NACLs, WAF for public-facing applications. We conduct a security posture review before each wave goes live and again 30 days post-migration.
IaC for Everything — No Console Sprawl
All cloud infrastructure — networks, security groups, compute, databases, S3 buckets, IAM roles — is provisioned via Terraform or AWS CDK, never manually in the cloud console. You inherit a Git repository containing your complete cloud infrastructure definition, applied via CI/CD. Console-created resources are tech debt from day one.
Post-Migration Managed Services Available
The migration is not the end — cloud environments need ongoing management, cost optimisation, security review, and architecture evolution. We offer post-migration managed services on a monthly retainer, providing monitoring, cost reviews, patch management, incident response, and architecture advisory as your workloads grow and evolve.
