What are cloud migration services?

Cloud migration services move your applications, databases, files and infrastructure from on-premise servers, colocation or older hosting to a cloud platform such as AWS, Azure or Google Cloud. A complete service covers assessment and discovery, migration strategy, a secure landing zone, the migration itself, testing, cutover and post-migration optimization. Some workloads move as they are, while others are modernized with managed databases, containers or serverless functions along the way. The goal is lower running costs, better uptime, easier scaling and stronger security without disrupting the business while the move happens.

How much do cloud migration services cost?

A single application migration usually costs $8,000 to $25,000, while multi-application or full data center migrations range from $40,000 to $150,000 or more. The main cost drivers are the number of workloads, the strategy chosen (rehost is cheapest, refactor costs most), data volumes, legacy technologies, integrations and compliance needs such as HIPAA or PCI DSS. A typical assessment costs a small share of the total and often pays for itself by finding workloads to retire. We provide a fixed quote after assessment, and our cloud migration services include optimization so savings start sooner.

How long does a cloud migration take?

A simple application can move to the cloud in 2 to 4 weeks. Larger migrations with many systems usually take 3 to 9 months, delivered in waves so the business keeps running. A typical timeline includes 2 to 4 weeks of assessment and planning, 2 to 3 weeks to build the landing zone, then migration waves of a few weeks each, followed by optimization. Timelines depend on data volumes, application complexity, change freeze periods and how quickly your team can test. Refactoring to cloud-native takes longer than lift and shift but delivers bigger long-term gains.

Which is better for migration: AWS, Azure or Google Cloud?

There is no single best platform. AWS offers the broadest set of services and the largest partner ecosystem. Azure suits businesses already using Microsoft 365, Active Directory, SQL Server and Windows Server, especially with license benefits. Google Cloud is strong for data, analytics, Kubernetes and AI workloads. As a cloud migration company we recommend the platform based on your workloads, team skills, existing licenses, compliance needs and budget, and we model costs on each option. Some businesses deliberately run a multi-cloud setup, which we can also design and manage.

Will there be downtime during cloud migration?

Most applications can be migrated with zero or near-zero downtime. We use continuous data replication, parallel environments, DNS-based switching and planned cutover windows in your quietest hours, so users barely notice the move. Some legacy systems need a short planned outage, often under an hour, for a final data sync. Before every cutover we agree acceptable downtime, success checks and a tested rollback plan with your team. This is one of the main reasons to use professional cloud migration services instead of moving systems ad hoc.

What are the 6 Rs of cloud migration?

The 6 Rs are the common strategies for each workload: rehost (lift and shift with no changes), replatform (small changes such as moving to a managed database), refactor (re-architect for cloud-native services), repurchase (replace with a SaaS product), retain (keep on-premise for now) and retire (switch off what is no longer needed). Some frameworks add a seventh, relocate, for moving VMware workloads as they are. As part of our cloud migration consulting we assess each application and choose the strategy that balances speed, cost and long-term value.

Is cloud migration secure?

Yes, when it is done properly, the cloud is often more secure than an ageing on-premise setup. We build a secure landing zone with identity management, multi-factor authentication, encryption at rest and in transit, network segmentation, logging and backups before any data moves. Data is transferred over encrypted channels, and access is limited to named engineers. We align the setup with HIPAA, PCI DSS, SOC 2 or GDPR where needed, and Webshark follows ISO 27001 certified processes throughout every cloud migration project.

Can you reduce our cloud costs after migration?

Yes. After migration we right-size instances, add autoscaling, use reserved instances or savings plans for steady workloads, move suitable jobs to serverless and tune storage tiers and data transfer. We also clean up idle resources and set budget alerts. FinOps reporting with proper tagging shows spend by team, product and environment, so you can track and cut costs month by month. Many businesses that simply lift and shift overspend in the cloud, so optimization is built into our cloud migration services rather than sold as an afterthought.

Which technologies do you use?

For cloud migration we work across AWS, Microsoft Azure and Google Cloud, using native tools such as AWS Application Migration Service, Database Migration Service, Azure Migrate and Google Migrate to Virtual Machines. Infrastructure is written as code with Terraform, CloudFormation or Bicep. For modernization we use Docker, Kubernetes, serverless functions and managed databases such as Amazon RDS, Azure SQL and Cloud SQL. Our engineers also work with application stacks including Node.js, Java Spring Boot, .NET, Python and PHP, so we can update code where a workload needs it.

Who owns the source code and IP?

You do. All infrastructure code, scripts, architecture diagrams, runbooks and any application code we change during your cloud migration project belong to you, and IP ownership is set out clearly in the contract. Cloud accounts are created in your name and billed to you, so you keep full control of your environment and data. We sign NDAs before discovery starts and hand over all credentials and documentation at the end. There is no lock-in, so you can manage the cloud in-house or move support to another provider at any time.

Can I hire a dedicated team instead of a fixed-price project?

Yes. Instead of a fixed-price project you can hire dedicated cloud and DevOps engineers on monthly contracts, from one engineer to a full team with a project manager and QA. This works well for long, multi-wave migrations, for businesses that want to modernize applications after moving them, or for teams that need ongoing cloud capacity without hiring in-house. You set priorities and the team works in your tools and ticketing system. Many clients start with a fixed-price assessment and then continue with a dedicated team. See our hire full-stack developers page.

Do you provide support after launch?

Yes. After go-live our managed cloud support covers monitoring and alerting, patching, backup checks, security updates, cost reviews, incident response and infrastructure changes, with response times agreed upfront by severity. Our team overlaps with US business hours for planned work and calls, and critical alerts are handled as a priority. You receive monthly reports on uptime, incidents, spend and recommendations. If you prefer to run the cloud yourself, we train your team and provide full documentation, and we can stay on a light retainer for complex changes.

Why Choose Our Cloud Migration Company

Cloud migration goes wrong when it is treated as a server copy. We treat it as a business project with clear cost, risk and performance goals.

Cost Control Built Into the Plan

Many businesses move to the cloud and see bills rise. We forecast costs before migration, right-size instances, use reserved and spot capacity where it fits, and set up budgets and alerts from day one. After migration, monthly reviews find savings in storage, compute and licensing, so the move pays for itself instead of becoming a new overhead.

Zero-Downtime Cutover Planning

Your customers should not notice the move. We plan migrations in waves, replicate data continuously, test in parallel environments and schedule cutovers in low-traffic windows with clear rollback plans. Database replication, DNS strategies and blue-green deployments let most applications switch over with zero or near-zero downtime.

How Our Cloud Migration Services Work

A proven five-phase cloud migration process keeps scope, cost and risk under control from assessment to optimisation.

Assessment and Discovery

Every engagement of our cloud migration services starts with knowing what you have. Over two to four weeks we inventory servers, applications, databases, integrations and licenses, measure current performance and hosting costs, and map dependencies between systems. Interviews with IT and business teams uncover constraints such as compliance rules, peak seasons and data residency. You receive an application inventory, a dependency map, a complexity score for each workload and a business case with expected savings.

Strategy and Migration Plan

For each workload we choose the right cloud migration path: rehost (lift and shift), replatform (small changes such as managed databases), refactor (re-architect for cloud-native), repurchase (move to SaaS), retain or retire. We group applications into migration waves, design target architectures on AWS, Azure or Google Cloud, and agree timelines, success criteria and rollback plans with your team. The deliverable is a wave-by-wave migration plan with costs, owners and risk ratings.

Landing Zone and Security Setup

Before moving anything, we build a secure cloud foundation, usually in two to three weeks: accounts and subscriptions, network design, identity and access management, encryption, centralized logging, backups and budget alerts. Everything is defined as code with Terraform or native tools such as CloudFormation and Bicep, so environments are repeatable and auditable. Requirements such as HIPAA, PCI DSS, SOC 2 or GDPR are built into this landing zone, not bolted on after data has already moved.

Migration Execution

We migrate applications and data wave by wave, starting with lower-risk systems to prove the process and build confidence. Tools such as AWS Application Migration Service, Azure Migrate and database replication keep source and target in sync, while automated tests and parallel runs confirm everything works. Each cutover follows a written runbook with clear go and no-go checks, scheduled in your quietest window, and our engineers stay on hand to resolve issues before users notice them.

Testing and Validation

After each wave we validate functionality, data integrity, performance and security. Row counts and checksums confirm that no data was lost, load tests prove the new environment handles peak traffic, and monitoring dashboards compare response times and error rates with the old setup. Vulnerability scans check the new configuration. Business users test their own critical workflows and sign off formally before we decommission old servers, so nothing is switched off until everyone is confident.

Optimisation and FinOps

Cloud migration is the start of savings, not the end. In the weeks after cutover we right-size instances, add autoscaling, move suitable workloads to serverless or managed services, tune storage tiers and buy reserved capacity or savings plans where usage is steady. Tagging and FinOps reports show cost by team, product or environment, so you see exactly where money goes each month. Many businesses find their biggest savings in this optimization phase rather than on day one.

Managed Cloud Support

After migration we can run your cloud for you with round-the-clock monitoring, patching, backups, security updates, cost reviews and incident response, under response times agreed upfront. Alternatively, we train your team over a few weeks and hand over documentation, runbooks, architecture diagrams and all infrastructure code. Many clients choose a mix, keeping us on call for complex changes. Either way, you end up with a stable, secure and cost-efficient cloud environment your team understands.
