Migrating to the Cloud Fast and Securely

There are numerous different ways to make your move to the cloud. According to Gartner, the five most common techniques are rehosting, refactoring, revising, rebuilding, or replacing. Yet every one of those options has a few commonalities: you will always need to understand what assets will be involved, how they communicate, and the ways they interact with your broader IT environment.

After helping organizations of all sizes and complexity levels simplify and accelerate their cloud migration projects, Guardicore has identified five simple steps that can streamline those common points. Following these steps helps assure a fast migration while also enabling you to ensure that security and compliance policies extend to the new infrastructure

5 simple steps to a fast and secure cloud migration

Ready for a sneak preview? Check out this short video for the quick overview before diving into the detailed instructions for how to achieve a fast and secure cloud migration.

1. Map application workloads

Typically, 73% of cloud migrations take more than a year to complete1. Even migrating a single application can take as long as four months2. However, with Guardicore, you can drastically speed up the timeline of your project from step one.

Once installed, Guardicore Centra automatically generates a detailed map of activity across all your environments. Process-level activity is correlated with network events, giving you a visual view of all workloads.
You can then drill down for more detail, including granular information on specific assets and processes. This helps you determine what elements you need to consider during your migration, so you can accurately scope your project.

2. Identify service dependencies

Many applications have service dependencies that they rely on to operate, such as DNS, active directory, or update services. These need to be documented and correctly configured as a part of the migration process.

For instance, you may not want your newly migrated cloud application to have access to the on-premises active directory for security or compliance reasons. Therefore, rehosting it or setting up another instance may be a better option for your business.

Guardicore can help you determine what dependencies exist today. Once those dependencies are identified, you can make a proactive and informed decision on how you would like to set up these services before you migrate. In this way you can avoid unplanned delays.

3. Identify business dependences

In addition to ensuring service dependencies are taken care of, other elements in your environment likely require access to the newly migrated asset to keep your business running as usual. One common use case for financial services organizations, for instance, is the need for billing, accounting, and SWIFT applications to communicate with a banking application migrated to the cloud.

In order to ensure that everything continues operating as expected post-migration, Guardicore provides you with the granular visibility you need to understand communication between each relevant element. This includes insights into connections between protocols, ports, and processes.

This visibility lets you plan how to configure for today’s dependencies. It also helps you decide whether or not to make a change moving forward (like creating a cloud instance of an accounting application in order to avoid an on-premises-to-cloud dependency). Moreover, it allows you avoid potential outages that can occur when you decommission on-premises versions of applications after a migration.

4. Migrate your assets to the cloud

Once you’ve gone through the process of mapping assets and thoroughly understanding dependencies, you can confidently begin your cloud migration. During this time, you can also define any segmentation policies needed to further reduce risk and ensure compliance.

Because Guardicore presents real-time and historical network data in a centralized platform, it’s easy to spot communication flows that might increase risk or result in non-compliance. You can then limit exchanges between assets as needed.

There is an additional bonus to defining policies before undergoing a cloud migration. Since Guardicore operates independently of the underlying infrastructure, policies follow the workloads. Thus, existing security controls carry over to the cloud. There, they can be fine-tuned for an asset’s new environment, saving even more time.

5. Check and validate your cloud migration

After you’ve completed your cloud migration, it’s important to do one last thorough check. Now is the time to validate that you have accounted for all dependencies and that the correct security policies are in place.

Once you’ve confirmed everything is as it should be, you can securely shut down any on-premises assets you want to decommission. All that’s left is to toast to a successful migration!

Congratulations on completing your fast and secure cloud migration!
