Azure Migration in a Nutshell
Azure migration implies moving to the Azure cloud applications, data warehouses, desktops, etc. to benefit from the reduced costs of IT operations, improved performance and scalability of migrated workloads, and more. Companies that want to migrate some workloads to Azure and keep others on-premises for regulatory compliance or other reasons, can opt for hybrid Azure migration.
ScienceSoft helps IT and non-IT companies migrate their workloads to Azure promptly and risk-free.
Azure migration steps: Defining migration goals scope, migration strategy selection, Azure migration project planning, pilot and full-scale migration, monitoring and optimization of the migrated workloads.
A team for Azure migration: a project manager, a business analyst, an Azure solution architect, a software engineer, a database engineer, a DevOps engineer, an IT security specialist, a QA engineer.
Azure Migration Steps
The Azure migration process depends largely on the number and complexity of workloads to migrate, the chosen migration strategy, and other factors. Below are outlined sample steps we at ScienceSoft take to complete Azure migration projects.
Step 1. Defining migration goals, scope, risks
- Eliciting business requirements and defining migration goals (boosting software resilience and performance, cutting workloads operational costs, etc.).
- Identifying workloads (applications, databases, data warehouses, desktops, etc.) to migrate to Azure.
- Identifying all sensitive information within the selected workloads to further plan appropriate security and compliance measures.
- Checking the compatibility of the to-be-migrated workloads with Azure and assessing their readiness for migration.
- Identifying risks of migrating particular workloads (e.g., long transfer time, issues with pulling data back to on-premises).
Step 2. Selecting an Azure migration strategy
- Choosing an appropriate Azure migration strategy, according to the migration goals. Among the strategies ScienceSoft applies in its migration projects are:
Rehosting (‘lift-and-shift’)
- Relocating workloads to Azure without code alterations.
- Quick and cheap Azure migration with limited cloud-driven capabilities (latency, performance, and scalability).
Best for: Workloads unlikely to be scaled and migration projects prioritizing short-term benefits (e.g., immediate reduction of on-premises infrastructure costs).
Replatforming (‘lift, tinker and shift’)
- Moving applications to Azure after introducing minimal code changes and some enhancements with no architecture changes.
- Increased performance and easy scaling of the migrated apps.
Best for: Applications that experience load jumps and unstable performance.
Refactoring (re-architecting)
- Modifying apps to make them compatible with Azure.
- Leveraging full-fledged cloud capabilities (auto-scaling, high resilience, serverless computing, etc.).
Best for: Making the migrated applications cloud-native.
- Deciding on a cloud deployment model (Azure public cloud, Azure Stack for private cloud deployment, on-premises + Azure deployment).
Step 3. Azure migration project planning
- Estimating the Azure migration project (including migration ROI, TCO).
- Working out the backup and disaster recovery plans to mitigate migration risks.
- Setting KPIs for Azure migration (CPU usage, workloads’ response time, accessibility to end users, node switchover time, etc.).
- Choosing tools for automated Azure migration.
- Designing the target architecture and planning modifications for workloads under migration.
- Planning measures to ensure the workloads’ security in the Azure environment, such as:
- Encryption of data in transit and at rest.
- Data storage access restrictions (Azure firewall and network security groups (NSGs).
- Multi-factor authentication (MFA) and complex passwords.
- API patching.
- Composing a plan for Azure migration with prioritized workloads for each iteration.
Step 4. Running pilot Azure migration (optional)
- Provisioning the testing environment for the workload-to-migrate.
- Replicating a workload to Azure.
- Evaluating the results of pilot Azure migration, making modifications to the workload architecture, configuring the Azure infrastructure (if needed).

BEST PRACTICE: For running test migration, ScienceSoft mainly chooses a non-critical workload that does not operate with business-sensitive data. |
Step 5. Migrating to Azure
Migration activities typically include:
- Preparing a production environment, setting up DevOps processes and tools.
- Migrating the data related to the workloads under migration and the workloads themselves.
- Checking the workloads for functioning as expected after migration.
Step 6. Monitoring and optimizing workloads in the Azure environment
- Configuring Azure monitoring tools (Azure Service Health, Azure Monitor, Azure Advisor, Microsoft Sentinel).
- Tracking the workloads’ performance and health.
- Right-sizing Azure resources in use for cost optimization with Azure Cost Management.
