Cloud migration is the process of moving digital business operations from legacy infrastructure or an on-premises data center either partially, or wholly, into the cloud. However, the term can also apply to moving from one cloud to another cloud.
Cloud migration is critical for achieving real-time efficiency, improved performance, and ease of expansion. Having a checklist ensures can make transition of business applications as smooth as possible.
So what is the 10-step cloud migration process?
Step 1: Designate a Cloud Migration Architect
Cloud migration architects are responsible for preparation and implementation of all aspects of cloud migration. These include creating the right migration framework and cloud-solution requirements during the migration process while recommending a suitable architectural solution to potential migration constraints. Before migrating to cloud, determine who will assume the migration architect role as this will entail many technical planning and decisions that is critical to the success of the project.
Step 2: Choose a Suitable Cloud Integration Level
Moving on-premises business applications to the cloud is through two methods: shallow cloud integration or deep cloud integration. Shallow integration allows minimal to zero changes to the servers, just moving or shifting business applications ‘as is’ which is why it is called lift-and-shift or forklift approach. Deep integration may entail auto-scaling (scale-on-demand approach) or using a serverless computing capabilities such as Azure functions or AWS Lambda.
Step 3: Choose the Right Platform and Provider
There are three levels of cloud platform services:
Software as a Service (SaaS): The service provider manages everything from development to management. Users have access via a web browser without downloading.
Platform as a Service (PaaS): You are responsible for creating the apps; the service provider only manages within the cloud platform.
Infrastructure as a Service (IaaS): Applications and software are built and managed in-house. The service provider oversees storage and infrastructure capabilities.
Step 4: Choose a Single or Multi-Cloud Approach
Discuss the pros and cons of using a single or multiple cloud providers. The best cloud platform for an organization is based on the following factors:
- feature set
- ease of platform
- cloud provider’s history
The option of running business applications across multiple cloud service providers will allow businesses to utilize key advantages on offer.
Step 5: Establish Cloud KPIs
Key Performance Indicators (KPIs) are metrics for measurement and assessment of task performances when it comes to achieving goals and expectations. These are the essential cloud KPIs for organizations of all types and in any industry:
- Duration: Estimated time for each phase of migration
- Disruption: The level and duration of downtime and delays to critical services, data centers, and day-to-day operations
- Cost: Capital investment, employee labor hours, and all expenses associated with the migration project
- Infrastructure: Hardware and network usage
- User Experience: Application’s availability, load balancing capacity, length of user sessions
Step 6: Establish performance benchmarks and baselines
Performance benchmarks and baselines provide an in-depth understanding of how workloads are functioning pre-migration. This is crucial for evaluation of post-migration implementation including what improvements are needed or how to tackle problems that arise.
Step 7: Create a Cloud Roadmap
Take inventory of business applications and generate dependency diagrams before deciding whether to leave the enterprise data center all at once or not and in what order. Migrate those with the fewest dependencies and adopt an incremental approach to those that are business-critical, have strict geographic stewardship requirements, or have high throughput.
Step 8: Migrate Data
Data migrations typically involve three basic steps: extract, transform, and load. Determine quality and stability of data before and after the move. Data back-ups are non-negotiable but also test if these work as expected.
Step 9: Evaluate Security Considerations
Cybersecurity is essential to protect sensitive data. An integrated cybersecurity plan to your cloud migration strategy will ensure that there is no risk of breaches or leaks during the entire process.
Step 10: Perform Any Necessary Refactoring
Refactoring is the process of running business applications on cloud infrastructure. This will help the applications to acclimatize to the new environment and function as effectively and efficiently as possible.
