Transitioning from on-premise infrastructure to the cloud is a strategic move for businesses aiming to enhance scalability, reduce costs, and improve operational efficiency. This guide provides a comprehensive overview of the migration process, highlighting key considerations and how Wanclouds' solutions can facilitate a seamless transition.
Understanding On-Premise and Cloud Infrastructure
On-Premise Infrastructure: Involves hosting applications and data on local servers within an organization's premises. While offering control, it often requires significant capital investment and ongoing maintenance.
Cloud Infrastructure: Utilizes virtual resources provided by third-party cloud service providers (CSPs) like AWS, IBM Cloud, and Google Cloud. Benefits include scalability, flexibility, and reduced operational costs.
Types of On Prem to Cloud Migration
When planning your on prem to cloud, understanding the different migration types is essential to choose the best approach for your business needs. Each type addresses specific infrastructure setups, workload types, and goals. Below are the primary types of migration commonly used:
1. Physical to Virtual (P2V)
P2V migration involves converting physical servers and on-premises hardware into virtual machines (VMs). This approach helps organizations move legacy systems into a more flexible virtual environment, making future on prem to cloud data migration easier.
- Use case: Companies with outdated physical servers aiming to consolidate and reduce hardware dependency before moving to the cloud.
- Benefits: Simplifies infrastructure management, reduces physical hardware costs, and improves disaster recovery options.
- Wanclouds Advantage: With Wanclouds’ automated assessment tools, your P2V migration can be planned precisely, ensuring minimal downtime and data integrity throughout the migration process.
2. Physical to Cloud (P2C)
The most direct on prem to cloud migration method is P2C, where physical on-premises servers and applications are moved directly into cloud environments like AWS, Azure, or IBM Cloud.
- Use case: Businesses wanting to quickly leverage cloud scalability and cost efficiency without intermediate virtualization.
- Benefits: Reduces CapEx by eliminating physical infrastructure, enables faster scalability, and simplifies maintenance.
- Key Considerations: May require some application refactoring or lift-and-shift strategies to ensure compatibility.
- Wanclouds Support: Wanclouds provides end-to-end services, including detailed pre-migration assessments, hybrid cloud strategies, and secure data transfer to optimize your P2C migration.
3. Virtual to Virtual (V2V)
In V2V migration, virtual machines running on-premises hypervisors (like VMware or Hyper-V) are transferred to similar virtual environments hosted in the cloud.
- Use case: Organizations with existing virtualization that want to move workloads seamlessly to cloud-hosted virtual infrastructure.
- Benefits: Retains existing VM configurations and settings, minimizing application downtime and compatibility issues.
- Wanclouds Edge: Wanclouds ensures seamless V2V migrations using automated orchestration and thorough validation to preserve performance and security.
4. Virtual to Cloud (V2C)
V2C migration moves virtual machines or containerized workloads from on-premises environments directly to cloud-native platforms.
- Use case: Companies transitioning from local virtualization to fully managed cloud services to gain elasticity and cloud-native benefits.
- Benefits: Unlocks cloud scalability, advanced monitoring, and managed service capabilities.
- Wanclouds Expertise: Wanclouds helps optimize V2C migration with refactoring services and cloud cost optimization tools, ensuring efficient workload management post-migration.
Specialized Migration Types
Lift-and-Shift (Rehosting)
A common approach in on prem to cloud migration steps is lift-and-shift, where applications and data are moved “as-is” to the cloud without changes.
- Benefit: Fast and cost-effective migration, ideal for legacy apps needing rapid cloud adoption.
- Limitation: May not leverage full cloud-native advantages like auto-scaling or serverless architecture.
Replatforming and Refactoring
For businesses looking to optimize after migration, replatforming involves small adjustments to improve performance, while refactoring means rewriting parts of applications to be cloud-native.
- Benefit: Enhances scalability, reliability, and cost-efficiency in the cloud.
- Wanclouds Role: We guide clients through these advanced steps with expert consultation and custom development, helping maximize cloud ROI.
Benefits of Migrating to the Cloud
- Scalability: Easily adjust resources based on demand.
- Cost Efficiency: Reduce capital expenditures and pay only for what you use.
- Enhanced Security: Leverage advanced security features offered by CSPs.
- Disaster Recovery: Implement robust backup and recovery solutions
- Accessibility: Access applications and data from anywhere with an internet connection.
Challenges in On-Premise to Cloud Migration
- Data Security and Compliance: Ensuring data protection and meeting regulatory requirements.
- Downtime: Minimizing service interruptions during migration.
- Compatibility Issues: Ensuring applications function correctly in the new environment.
- Cost Management: Avoiding unexpected expenses during and after migration.
Step-by-Step Cloud Migration Process
- Assessment and Planning: Evaluate existing infrastructure, identify applications for migration, and define objectives.
- Choosing the Right Migration Strategy: Select the most suitable approach (e.g., rehosting, refactoring) based on business needs.
- Selecting a Cloud Service Provider: Choose a CSP that aligns with your requirements.
- Designing the Architecture: Plan the cloud environment, considering scalability, security, and compliance.
- Migration Execution: Transfer applications and data to the cloud, ensuring minimal disruption
- Testing and Validation: Verify that applications function correctly and meet performance expectations.
- Optimization: Monitor performance and costs, making adjustments as necessary.
