Cloud migration means moving your data, software, and applications from your old computer systems or local servers to internet-based servers (the cloud). It is similar to transferring files from your personal device to Google Drive or iCloud so that you can access them anytime from any device.
Earlier, companies stored data and software on their office servers. This limited accessibility and required heavy maintenance. After cloud migration, the same data and systems shift to online cloud platforms such as AWS, Microsoft Azure, or Google Cloud. Employees and customers can then access everything securely from anywhere with an internet connection.
Why is cloud migration important ?
Cloud migration is important because it improves operational efficiency, scalability, agility, and security while reducing hardware and maintenance costs. With cloud platforms, businesses get modern infrastructure, automated updates, disaster recovery systems, and global access.
Migrating to the cloud helps organizations:
- Modernize IT systems and avoid hardware limitations
- Reduce cost related to servers and data centers
- Improve security through advanced cloud protection tools
- Enable remote work and global collaboration
- Adopt emerging technologies such as AI, data analytics, and automation
Cloud adoption allows IT teams to focus on innovation rather than maintaining physical machines and servers.
Why companies do cloud migration
- To save money on hardware and maintenance
- To increase speed and performance
- To access data and apps from anywhere
- To improve security and backup
- To scale easily as the business grows
- To enhance customer experience with fast applications
- To prepare for digital transformation and AI innovations
Understanding Cloud Migration Strategies:
When planning a cloud migration, organizations typically follow one of these proven strategies:
1. Rehosting (Lift and Shift)
Applications are moved to the cloud as-is using cloud migration solutions like automated VM transfer. It’s fast and low-risk, ideal for legacy systems, but may lead to higher long-term operational costs without cloud-native optimization.
2. Replatforming (Lift, Tinker, and Shift)
Cloud migration solutions help make minor changes—like switching databases or OS—to improve scalability. This approach balances speed and performance without full redevelopment, making it suitable for medium-complexity applications.
3. Repurchasing (Drop and Shop)
Organizations replace old software with SaaS platforms using cloud migration solutions to transfer data. It reduces maintenance work and offers modern features, though user training is required.
4. Refactoring (Re-architecting)
With advanced cloud migration solutions, applications are redesigned into cloud-native structures using microservices and automation. It offers maximum scalability and efficiency but demands high skills and time.
5. Retiring
Using cloud migration solutions, companies identify outdated applications and remove them to save storage, costs, and effort. This prevents unnecessary migration tasks.
6. Retaining
Some applications stay on-premises, and cloud migration solutions help integrate them into hybrid environments. This is necessary for compliance, data security, or low-latency needs.
7. Relocating
Cloud migration solutions enable full infrastructure movement with minimal changes that is ideal for datacenter exits. It speeds large-scale migration but may require optimization later for better cost and performance.
Types of Cloud Deployment
- Public Cloud
- Private Cloud
- Hybrid Cloud
- Multi-Cloud
Businesses choose these models based on security needs, cost structure, and scalability requirements.
Migration Service Models
- Software as a Service (SaaS) – Ready-to-use applications accessed via browser
- Infrastructure as a Service (IaaS) – Virtual servers, storage, and networking resources
- Platform as a Service (PaaS) – Development platforms with built-in tools and services
Common Cloud Migration Solutions and Challenges
| Challenge | Solution |
| Downtime during migration | Use phased migrations and maintain parallel environments |
| Data loss or corruption | Implement robust backup and validation procedures |
Skills gap in cloud technologies | Invest in training and partner with cloud experts |
Unexpected costs | Use cost estimation tools and implement budget alerts |
Application compatibility issues | Conduct thorough testing in pre-production environments |
| Security vulnerabilities | Follow cloud security frameworks and best practices |
| Vendor lock-in concerns | Design with portability in mind and use open standards |
Cloud Migration Planning: Essential Steps
1. Assessment and Discovery
- Inventory all applications, databases, and workloads
- Identify dependencies and integration points
- Evaluate current infrastructure performance and costs
- Determine which workloads are cloud-ready
2. Business Case Development
- Calculate total cost of ownership (TCO)
- Define success metrics and KPIs
- Identify potential ROI and payback period
- Secure stakeholder buy-in and budget approval
3. Cloud Provider Selection
- Compare AWS, Azure, Google Cloud, and other providers
- Evaluate pricing models and available services
- Consider geographic availability and compliance certifications
- Assess support and service level agreements
4. Security and Compliance Planning
- Define data governance policies
- Implement identity and access management (IAM)
- Plan for encryption at rest and in transit
- Address regulatory requirements (GDPR, HIPAA, SOC 2, etc.)
5. Migration Execution
- Create detailed migration runbooks
- Set up cloud landing zones
- Migrate in phases starting with low-risk workloads
- Maintain rollback plans for critical systems
6. Post-Migration Optimization
- Monitor performance and costs continuously
- Right-size resources to avoid over-provisioning
- Implement cloud cost management tools
- Train teams on cloud-native best practices
Automating Cloud Migration with Zasya Solutions
Cloud migration becomes faster and more reliable when businesses use automation. Cloud migration solutions, combined with smart automation tools, help companies move applications, data, and systems to the cloud with less manual effort and fewer errors. At Zasya Solutions, we use automated cloud migration solutions and techniques to ensure the entire process stays smooth, secure, and scalable.
Key Automation Methods We Use
1. Backup and Restore Automation
We take a secure backup of your current systems and restore them on the cloud. This method helps move your workloads quickly without making big changes.
2. Scan and Re-Create Automation
We scan your existing environment to understand its structure and settings. Then we rebuild the same setup in the cloud automatically to ensure consistency.
3. Infrastructure as Code (IaC)
We create and manage cloud infrastructure using code instead of manual steps. This ensures faster deployment, easy scaling, and consistent environments.
Popular IaC tools we leverage:
- Terraform for multi-cloud infrastructure provisioning
- AWS CloudFormation for AWS-specific deployments
- Azure Resource Manager (ARM) templates
- Ansible for configuration management
4. Automated Testing and Optimization
After migration, we run automated checks to ensure everything works correctly. We then optimize performance, security, and costs to get the best results from the cloud.
5. Continuous Migration Pipeline
We establish automated pipelines that enable ongoing migrations and updates, ensuring your cloud environment evolves with your business needs.
Conclusion
Cloud migration is essential for modern businesses that want to improve efficiency, reduce costs, and stay competitive.
