The question of moving, no matter whether migrating to a well-known public cloud service vendor of the type as Amazon Web Services (AWS), Google Cloud Platform (GCP), or Microsoft Azure, or from one cloud platform to another one, is always the problem that the businesses are facing and they should find solutions to it.
Nevertheless, if a strategic cloud migration plan is deployed, numerous perks include enhanced agility, scalability, and cost savings, propelling organizations toward digital transformation and innovation.
What is a Cloud Migration Strategy?
A cloud migration strategy is a complex approach commonly used by organizations and businesses in information technology to move their digital assets, including applications, data, and IT resources, from on-premises or colocated infrastructures to cloud environments.
It generally consists of the steps, approaches, and factors needed to get the migration going and ensure the experiences are good.
1. Preparation
Firstly, the project’s fundamental part involves evaluating the deployment ecosystem, including applications and the data backing the organization’s current IT infrastructure.
It involves identifying the appropriate migrating assets, understanding the dependencies between the systems, analyzing the security and compliance requirements, and designating the migration goals and timelines.
2. Planning
Organizations will design an in-depth route in the planning stage leading to an efficient migration process.
Moreover, selecting a relevant cloud service provider and deployment model (public, private, or hybrid cloud) and the formation of the reasons for movement (lift-and-shift, re-platforming, or re-architecting).
Estimating the expenses, setting the priorities, and the dates of movement are among the means chosen to achieve this goal.
3. Migration
The first phase is the migration itself, where carefully devised migration activities will take place, covering data transfers, application configurations, and network and security policy frameworks.
The duration of this transitional game depends on what migration scheme is selected. It can be more accessible, as in the case of just data transfer, or more complex, as in the case of complete migration of applications.
4. Operation
Once we have moved to the cloud, we will focus mainly on efficient and correct management of the cloud environment. This involves managing resources, responding to errors, installing backup and data recovery procedures, and adhering to security and governance guidelines.
5. Optimization
Consistent enhancement should then be considered to best reveal the long-term benefits of cloud migration.
Organizations carry out risk assessments of their cloud environment, identify areas for improvement, and make the necessary changes to achieve better performance, cost-effectiveness, and scalability.
Such processes can be implemented by downsizing the resources, optimizing cloud-native services, automating processes, and developing best practices.
