HOW TO MIGRATE TO CLOUD ACCORDING TO EXPERTS

Although it often happens, migration doesn't have to be rushed. An undercurrent migration strategy can result in expensive time, data loss and other obstacles when you plan to modernize your company's IT infrastructure.

Following are some ways to migrate to the cloud for your data and applications, which can be selected as your migration strategy. one of the best places to migrate today is MITEL CLOUD.

Choose How to Migrate to the Appropriate Cloud

Migration can occur in both directions, from physical servers to cloud and vice versa, from private cloud to public cloud. Each scenario is different based on your application. In essence, you have to know where to start and where to go.

Option 1: Data Migration Only

several options for how to migrate to the cloud for data and applications. This is usually the right choice for Tier 1 (Interface / ERP) and Tier 2 (Engine / Logical Process) Applications. If you choose to migrate your VM or vApp, this will still change. If your Tier 1 application cannot be too much downtime, the best recommendation is to make a kind of replication. Replication is quite complex, it needs to be detailed in it, but the key to understanding this is useful for identifying data size, rate of change and bandwidth between source and target.

As a general rule, if your change rate is greater than or equal to bandwidth, your migration will tend to fail. That's because of the level of change in spurring everything in the application. This can increase potential problems during the process. Bandwidth speed is needed until the migration process is complete. You need a high enough bandwidth to go through the improvement/change process.

Option 2: Machine Replication

This is best for Tier 1 and 2 Applications which have a higher tolerance for downtime and this will involve stack migration. This scenario will be less in terms of configuring, there will be more data migration activities. This option is ideal if you move to an internal private cloud. You will be able to replicate the entire stack because you have a lot of bandwidth for the transfer process. It is important to note portability on the basis of VMware technology. This is because VMware allows you to package the entire VM / vApp and the entire stack, into OVF. The OVF can then be transported anywhere if it's already a virtualized physical server.

Option 3: P2V Migration

This migration option is usually for non-virtual Tier 2 and Tier 3 (Storage / DB) Applications. This concept involves taking physical applications and virtualizing. VMware has a VMware converter that does P2V, and it's quite easy to migrate from physical to the private cloud using P2V. However, the options are completely different from best practices, and you should do further research to ensure that you have the latest updates on best practices and advice from experts. In option three, there is no replication. However, the application can be sent to public cloud service providers to run in the public cloud after virtualization is complete.

Option 4: Disaster Recovery


A road was often taken by several large companies, usually as a Disaster Recovery (DR) scenario. This process will prepare something to do on the basis of replication from the physical to one machine and to another. You can choose to replicate the entire stack from point A to point B, and then click the failover button.

Now, let's say you have identified the best choice for migrating your application. Before you can really do it, there is still little information for evaluation.

Understand the Potential Risk of Your Data for the Migration Process

When migrating Tier 1 applications from the physical data center to private cloud or public, we must consider the gravity of the data, and the data itself will be the hardest part of the migration process.

There is no easy way to streamline data, so you need to evaluate the volume level of data in your application considering migration. Especially if you are a company that has a high transaction frequency, or if it is a high transaction application, there will be a lot of data to be replicated. Data from the application is 99% of the gravity of the data from the application.

Another aspect that must be evaluated as part of your pre-migration plan is to determine how the VM or VAPP relates to other applications. If you have many applications that are tightly integrated into applications that want to migrate, the cloud may not be an option for that application.

Identify How The Application Is Connected

Does your application have data that needs to be accessed by other applications quickly? If so, the principle of "all or not" data migration is your best choice. If you have applications that are tightly coupled to two or three other systems, you might be able to move them all to the cloud together. Because they are still closely combined, you will not experience latency that will occur if your cloud-host application needs to access the physical server to get the data needed to run.

Identify how many applications are related to the application you want to migrate. After that, the identification of applications that are sensitive to latency problems. How sensitive it must be a consideration, so you can determine whether you will migrate the application or not.

To be able to check the best practices on how to migrate to this cloud from your list, you must be absolutely sure by understanding all the relevance of your application. So you won't be surprised after the migration process.


Every application and migration strategy is unique, so there are no detailed manual instructions that work for everyone. Thus the explanation of several options for migrating to the cloud for your applications and data in order to improve your IT infrastructure. Maybe useful.
