Since 2012, ScienceSoft has been providing cloud migration services to help businesses increase their workloads’ performance and reduce IT infrastructure operational costs.
Based on our recent projects, ScienceSoft shares some details on cloud migration:
Migration of a company’s first workload takes from 1-2 months (for small workloads) to 6+ months (for medium and large workloads). Subsequent workloads require less time to migrate due to the gained experience.
The migration costs are $5,000 – 15,000 for small workloads and $20,000 - $500,000 for medium/large workloads.
Key project steps: cloud migration conceptualization, choosing a cloud migration strategy, cloud platform selection, cloud migration planning and design, migrating to the cloud, final testing and optimization of the cloud environment.
Every cloud migration roadmap is different, depending on the scope and scale of your migration project, the chosen migration strategy, the complexity of data storing and processing requirements, and more. Below are described the typical steps we at ScienceSoft take to perform cloud migration.
Cloud migration conceptualization
- Establish cloud migration goals (improving business app performance, reducing IT infrastructure costs, expanding market reach, etc.).
- Determine workloads (e.g., enterprise applications, databases, data warehouses, virtual desktops) to relocate to the cloud.
- Diagram the workloads’ topology and dependencies and perform the workloads' complexity analysis to define the scale of the cloud migration.
Choosing a cloud migration strategy
- Choose a cloud migration strategy (rehost, replatform, refactor, repurchase, retire, retain – or a combination of several strategies):
- Rehosting (“lift-and-shift”):
- Migrating on-premises workloads to IaaS without code modifications.
- Quick and cheap migration to the cloud with limited cloud-driven capabilities (workload resilience, performance and scalability).
- Replatforming (“lift, tinker and shift”):
- Migrating modified workloads to the cloud (no change in the workload architecture is needed).
- Improved performance, fault-tolerance, and scaling of the migrated workloads.
- Refactoring (“rearchitecting”):
- Moving on-premises workloads to PaaS by making them cloud-native (or near native).
- Full scope of cloud capabilities (including cloud auto-scaling, serverless computing, etc.)
- Repurchasing (“drop and shop”):
- Replacing an on-premises solution with a cloud software product (SaaS solution).
- Fast and low-risk cloud adoption.
- Rehosting (“lift-and-shift”):
- Choose a cloud deployment model (single cloud, multi-cloud or hybrid cloud):
- Single cloud:
- Deploying your workloads in a single multi-tenant cloud environment.
- Risks of vendor lock-in.
- Migrating your workloads or their parts to different public clouds.
- Leveraging key advantages of each cloud service provider (e.g., one provider offers higher database speed, while another one offers more advanced AI capabilities).
- Hybrid cloud:
- A combination of public and private (hosted and managed on-premises by the company itself) clouds.
- Placing the workloads with specific security requirements on the private cloud and enjoying the public cloud’s pricing benefits for other workloads.
- Single cloud:
Cloud platform selection
- Choose one or several cloud platforms (AWS, Azure, Google Cloud Platform, etc.).
- Validate the compatibility of the workloads under migration with the cloud and a particular cloud platform with the help of a Proof-of-Concept (PoC).
Cloud migration planning and design
- Calculate cloud computing resource requirements for your workloads to avoid buying redundant resources.
- Develop a risk management plan to anticipate and mitigate such risks as overpaying due to improper workload architecture, compromised data security during data migration, etc.
- Perform cloud migration cost assessment and ROI calculation.
- Establish KPIs for cloud migration (workloads’ response time, availability, error rate, etc.).
- Identify the amount of refactoring needed for the workloads under migration.
- Select tools for automated cloud migration.
- Design the architecture of the workloads to migrate.
- Prepare a cloud migration plan, prioritizing workloads to migrate and outlining a migration schedule.
Migrating to the cloud
Common migration activities include:
- Creating a new production environment based on the new workload architecture.
- Migrating data related to the workloads under migration. To keep the cloud database up-to-date, data migration should be done continuously throughout the migration process.
- Migrating workloads.
- Setting up cloud monitoring tools.
Final testing and optimization of the cloud environment
- Test the performance of the migrated solutions in the cloud environment.
- Conduct penetration testing of the new environment.
- Conduct regulatory compliance assessment (e.g., compliance with HIPAA, GDPR, etc.) and technical audit (to identify operational flaws) of the cloud infrastructure and the migrated workloads.
- Improve security (if needed) and optimize cloud performance.
Switching from on-premises workloads to the cloud
At this stage, the migration is complete, and your cloud environment goes live. Upon going live, you may either turn off the on-premises infrastructure of the migrated workloads or keep it for backup or as part of a hybrid cloud deployment.
