Cloud Application Migration
Network:34


I have a large, hybrid Cloud application migration starting. Can anyone point me to some good guides and workbooks on Cloud application migration? My client hasn't decided on a Cloud technology vendor yet, but I would like to start getting the application assessment going. Any suggestions would be appreciated. Thank you.

I lead the same time ago. I can write several lines but the critical success factor is thinking about the organizational/enterprise architecture (business, application, technology, security, information layers) to take into account all impacts. If you think is a technical matter then the chances to fail are high. Regarding to vendor or service provider (just in case you will decide to use one) contract is the hardest component. For example, when you take into account the enterprise architecture, who the vendor will assure the business continuity or the security?. Take into account that you can not put all data into cloud due to sensible data created for some people into your company (we use an hybrid model for example).

You are welcome. I can not say to much because it was an strategical (real strategical) initiative but I wrote what I beleive is critical to take into account.

We are in the process of moving healthcare data from self hosted to cloud environment. So, I'm very interested to learn more from this thread. Anyway for healthcare business associate agreement (BAA) is very critical, since HIPAA BAA will protect us from data breaches and compliance issues.

Thanks for posting this, Lon.

Are you migrating from bare metal to cloud? Or are changing cloud providers? Realistically, the cloud is just another way to store data. Managing a bare metal application migration isn't much different. Standing up a cloud environment, once the infrastructure is in place is actually easier, theoretically.

As mentioned in posts, protecting data (PCI, SPI, HIPAA) can be challenging on the cloud.

Hi Bob,

It's a financial institution with a combination of virtual and physical platforms. They want to move to a hybrid cloud but haven't decided for sure on the vendor. The migration challenge seems to be in profiling each of their 9000 applications and figuring out which ones will do well in the cloud and then deciding where to put it, private or public cloud. The second challenge will be convincing security and governance to let us migrate into the cloud. (always a good time) Lastly, the 9000 apps are scattered around the world. Trying to find them and mapping their dependencies and upstream/downstream data flows will be tough.

I'm thinking the forward challenges once we start, will be post-migration security and data integrity and performance monitoring, and then trying to ramp up so the 9000 apps don't take forever to complete.

I'm on a 10 month contract with them that starts next week, so that will also be a constraint, especially if I want to be renewed, I will need to show a lot of progress within the 10 month window. The unfortunate reality is that a person can easily spend 10 months just trying to figure out the specifics of all 9000 applications, their locations and data mappings.


Thanks for the great replies. Happy holiday's everyone.

9000 apps? Standing up the cloud environment will be the easy part. So they are going to keep some things in the current environment and move some apps to the cloud?

One challenge will be security for customer facing apps in the cloud. Will there be adequate protection for PCI/SPI data with the vendor you choose, can they build private DMZ's that will 'quarantine' your sensitive data from others that share the same VM cluster?

Another will be the interfaces between apps in the hybrid environment. As well as having the time to set up the Development, Test, Stage and Production environments.

When do they want the cloud environment to go live?

All excellent questions Bob. Those will be the same sort of questions that I will be asking once I get onboard.

By getting the low hanging fruit first, I can get them some ROI fairly quickly. I'm putting a lot of faith that the vendors discovery and migration tools are mature and robust.

Exactly!! Find the apps that are not mission critical and test them in the cloud first, then migrate them. You will get some early wins and that will keep the sponsors happy.

I would suspect that the vendor will be able to work your migration. Perhaps don't give them all the work up front, just part of it...with the incentive to get the rest of the work if they are successful with the initial work?.

Also, I would definitely do this in phases.

I love your idea of giving them a 2-3 application migration audition before giving them the big contract. Thanks!
