Prior to migration, you need to build a virtual datacenter in your cloud, including connectivity, networking, storage, and identity – elements comparable to your on-premises environment.
By building this virtual datacenter, you can ensure that your applications will continue to support the business after migration, without surprises. Building this in the cloud is a streamlined process, as you can leverage available components for fast assembly and configuration. Many excellent tools as well as guidance can help accelerate this step, but below are some of the basics— and why they’re important to migration.
As with your on-premises environment, you need a way for users to be identified and authenticated to ensure secure access to your new cloud resources. In most cases, this means running active directory or a similar solution. You could simply extend your on-premises identity to the cloud to support the migrated workloads. However, many cloud providers have built-in identity solutions provided as a service. These can also integrate with your on-premises identity systems to enable single signon for user convenience. As your workloads will now be stored within the cloud, you’ll also want seamless access for users between your existing on-premises systems and the systems you’ve migrated.
