Cloud migration process
Running your applications in the public cloud has several cost and effort benefits. Many organizations are planning and preparing to move their applications to the cloud to reduce the capital expenses, and the support and administrative costs. Moving into cloud computing requires a lot of planning because you need to determine what it costs to run the same servers in the public cloud before you can finalize the move. Also, after the move, you need to continually focus on how to optimize your cloud-based application in order to increase cost savings.
TrueSight Cloud Cost Control enables you to simulate the migration of the servers in your current infrastructure to the public cloud and provides you with the migration cost estimates. You can use the cost estimates to make an informed decision about moving to the cloud. The simulation algorithm uses one of the most common cloud migration strategy, called Lift-and-Shift.

Key phases of the cloud migration process
The following image shows the five key phases of migrating your servers and applications to the public cloud. The table that follows provides a brief explanation of each phase and how TrueSight Cloud Cost Control supports it.
| Phase | Summary | Using TrueSight Cloud Cost Control |
|---|---|---|
1. Assess | Assess the opportunity to migrate. Analyze the cost and benefits of migrating to the cloud and determine which part of your IT portfolio do you want to migrate. You need to evaluate whether it is beneficial to migrate your architecture, your business service, your machines, or your applications to the cloud. | TrueSight Cloud Cost Control enables you to review and analyze the costs of your current infrastructure. You can simulate the migration of your servers or application (business service) to the cloud, and review and evaluate the migration cost. For example, you can simulate migration of a subset of servers that are currently hosted in your on-premises data center to the public cloud and review the cost difference to evaluate whether they are the right candidates for migration. For more information, see Estimating the cost of migrating servers to the public cloud. |
2. Analyze | Review and analyze the size, resource configuration (vCPUs, memory, disk), and cost of the current infrastructure to identify the servers and applications that are probable candidates for migration. | You can review the currently used servers and business services to decide which can be migrated. For example, you might want to select the most expensive business service that is using servers hosted in your on-premises infrastructure. For more information, see Analyzing and forecasting multi-cloud costs. |
3. Plan | Plan the migration schedule, identify the people who will be involved in the migration, and define the migration specifics. For example, which AWS instance type do you want to choose for your current VM. | The migration simulation results page provides details about the instances that you can provision on the cloud for the servers in your current infrastructure. For more information, see Estimating the cost of migrating servers to the public cloud. |
4. Migrate | Migrate and validate the migration. This is the actual migration phase. | Use the portal of the public cloud provider. TrueSight Cloud Cost Control is not involved in this phase. |
5. Optimize | Optimize the migrated servers to increase cost savings. Regularly review and evaluate the cost of your servers in the public infrastructure. | You can review and analyze the current and projected cost estimates of your current infrastructure by different dimensions such as cloud service, cloud provider, and so on, and evaluate whether there is further opportunity to optimize them. For more information, see Analyzing and forecasting multi-cloud costs. |
Migration simulation strategy
TrueSight Cloud Cost Control uses the Rehosting or Lift-and-shift cloud migration strategy to simulate the migration of a set of servers to the public cloud. With this approach, servers are replicated or re-hosted on the target public cloud without any redesigning. This is one of the most commonly used cloud migration strategies.
The migration simulation algorithm considers the hardware configuration of the servers to be migrated and proposes instance types with the same configuration on the public clouds. If two instance types with the same configuration are available, then the algorithm chooses the cheaper one. For more information, see Estimating the cost of migrating servers to the public cloud.
