A cloud migration strategy is a plan an organization develops to move its data and applications from an in-site architecture to the Cloud. Not all workloads benefit from running on cloud-based infrastructure, so checking out the most effective ways to prioritize and migrate applications before startup is essential. Having a systematic and documented strategy is crucial.
Cloud Migration Process
Your accurate roadmap for migrating to the Cloud depends on the size and complexity of your environment. These are the basic steps:
Planning your migration: Before you begin, you should be clear about your reasons for moving and the strategy that best supports it. Start by assessing your current environment. It’s essential to calculate cloud server requirements based on current application resource requirements to avoid buying more than you need.
At this crucial stage, you’ll need the resources and expertise of a specialist. An application performance management solution can provide complete real-time visibility of your environment and all its dependencies during strategy execution as part of the package.
What Are The Types Of Cloud Migration Strategies?
These are the six most common approaches, widely known as the “Six Approaches to Deportation”:
1. Rehosting (“Upload and Move”)
As the name suggests, that includes uploading your sequential offer and moving it from on-site hosting to the Cloud. You’re transferring a replica of your existing environment without making large-scale changes to achieve the fastest ROI. Companies with a conservative culture or that don’t have a long-term strategy to exploit the potential of the advanced Cloud are well suited for rehosting.
2. Transfer Apps
As a variation of lifting and moving, moving applications involve making additional adjustments needed to improve the horizontal position of the Cloud. Once again, the application infrastructure remains the same. It is also a good strategy for conservative organizations that want to build trust in the Cloud while realizing benefits, such as increasing system performance.
It means moving your apps to a new native cloud product, the most popular SaaS platform (for example, moving CRM to Salesforce). The challenge is to lose familiarity with the current code and train your team on the new platform. However, repurchase may be your most cost-effective option if you move from the old, highly customized horizontal mode.
Reanalysis (or replanning) means rebuilding your apps from scratch. It is driven by your company’s need to take advantage of cloud capabilities not available in your current environments, such as automatic scalability on the Cloud or serverless computing. Reanalysis is generally the most expensive option, but it’s also compatible with future releases.
Once you’ve evaluated your application portfolio for cloud readiness, you may find that some apps are no longer helpful. In this case, disable it. The resulting savings may enhance your company’s status for migration-ready applications.
For some organizations, using the Cloud doesn’t make sense yet. Can’t you pull data from the company’s website for compliance reasons? Probably not ready to prioritize a recently upgraded app? In this case, I plan to revisit cloud computing later. It would be best if you only migrated what makes sense for your business.
What are the Benefits of Migration to the Cloud?
On a fundamental level, the power of the Cloud lies in its resilient infrastructure. This feature manifests itself in several different ways, including but not limited to:
Low hosting costs: In the Cloud, you don’t have to worry about the costs and conditions of keeping existing physical servers running. A third-party data centre manages servers often located on a subscription-based model and reduces capital expenditures.
Flexibility and scalability: The CIO classifies process speed as a critical driver of cloud adoption, according to Gartner. Cloud-based services automatically expand capacity to suit growing or volatile demand and allow teams to collaborate on app updates or issues from anywhere rather than from location. This level of continuity can give companies a real competitive advantage.
Reduced space: As server capacity increases and decreases to suit your cloud needs, you only use the energy and resources you need. You can even reduce your data centre set to one or even zero to minimize the environmental impact.
Disaster Recovery: This is important for businesses of all sizes, but it has historically proven to be expensive for small businesses. Today, the Cloud is helping more organizations implement time-consuming backup and recovery solutions and upfront investments.
Security: The Cloud provides more excellent protection than data centres by centrally storing sensitive data and applications. Most cloud service providers also prevent unwanted traffic from accessing your data by rolling out regular security updates, protecting you from security threats, and giving you the freedom to take care of what’s essential to your business.
