Pre-requisites of migration

1. Future prospect of the business- Before migrating to the cloud, the company should definitely foresee all the future prospects of the business with the help of the researchers and analyzers. The envision of future needs will only be the deciding factor whether your business requires cloud migration or not. Hence a strategy must be prepared and each concerned person must be fully aware of the circumstances and results. To come up to the best decision, the company should go through the pros and cons of cloud migration and get proper feedback from already cloud migrated enterprises for better understanding.
2. Outlining the cloud model – Once the business gets migrated to the cloud, roles and responsibilities change for many team members of the organization. Hence, each member must be properly informed about the changes in the infrastructure. In this way, the duties are separated and business activities are ensured. It also involves identifying and understanding the workloads and what are their supporting systems. The best way of doing this is by discovering elements like application to application, application to VM and VM to physical machine dependencies. After this has been done, deciding for the number of accounts a company will have or should be given grant access to.
3. Training the staff – Migrating to the cloud is not the end solution making your staff adaptable to the cloud environment is also a sole responsibility for any company. Once the whole staff gets that required technical expertise, things become more smooth and at a fast pace. But this should happen at a very early stage as any delay in this may lead to disruptions at the organizational level.
4. Capturing current and targets by KPIs- Capturing current performance and what can be the future capabilities. Though this might require coordination with different stakeholders and other issues involved. In spite of these issues, understanding the current performance baselines should be the immediate action for any enterprise which is going for cloud migration. In the middle of this not forgetting about the targets that you would have dreamt of for your company should not be ignored. Setting the KPIs (Key Performance Indicators) would be the approach to this. The staff that has expertise in the domain should look out whether the targets are aligned with the new cloud environment and if not then what changes are required.
5. Selecting the best cloud service provider- Once you have gone through all the prerequisites, the major step comes of selecting the best and most suitable cloud service provider for your business. There is no harm in trying out multiple options before deciding for that one.

Steps during migration

1. Automation- Any cloud platforms’ dexterity can be tested through automation. Try to automate most of the operations and if possible all. To achieve the highest level of automation, the structure of the organization should be consistent and transparent and this might demand a stretched time.
2. Transform the internal processes- To enjoy the maximum efficiency of any cloud service it is very important that the conventional internal processes must be transformed accordingly. More the number of processes will be transformed and aligned to the cloud platform; more empowered will be your business. All the BI applications must be migrated along with the custom reporting tools and data applications.

Post migration

1. Monitoring is mandatory- Even after the migration has been successfully done, the system requires 24/7 monitoring to ensure whether all the processes are in line with the architecture. Even a single ignorance within the infrastructure can lead to future losses.
2. Ensure cloud-native monitoring tools– Although there are multiple tools available, an expert like cloud needs the best cloud-native monitoring tool so as to find the bestway to fit into the business.
3. Keep the single point of contact- If you have purchased the cloud-based service from a reputed cloud service provider, and then it would be for the best that a single point of contact should be kept with the support centre of your cloud service provider.

All these steps performed at the right time during cloud migration can literally bring miracles in your business. Cloud migration must be carried out in accordance with the best practices. But apart from all this, the onus lies on you to keep a track of the records and results, benchmarks to be set and what would be the deviations. All this together will ensure a successful cloud migration and your company reaching the optimum level of ROI.
