Cloud IT needs one migration or another

HP 3000s are being displaced because the servers are aging, at least in some managers' views. But moving IT operations of an organization to cloud-based providers also looks attractive to a company that wants to give up on the local datacenter concept. Why make the ongoing investment in staff and new hardware and maintenance, they figure, when a supplier like Amazon Web Services or even HP's Cloud can handle that systems service?

You just need to remember there's two migrations in a cloud transition. There's a new aspect emerging in cloud migration. It's being called Data as a Service. You must separate your application from its data during the migration phase, according to Michael Daconta, VP of advanced technology at InCadence Strategic Solutions. He's the former metadata program manager for the Department of Homeland Security. Metadata tagging is a part of DaaS, he explained in an InformationWeek article.

A 3000 site that's migrating will be counting on replacing its application in order to shut off the local datacenter. That's the ultimate separation of app and data. App replacement is today's popular choice to transition off the 3000. But there's still a migration to made, even if a replacement app can be used instead of doing a lift and shift of code. Companies have to migrate their data to the cloud, too.

Data migration is just as crucial as replicating the business rules and functions of the 3000's app. This migration also introduces the opportunity to employ the powers of Master Data Management. MDM gives the company the path to a One True Source of data. A half-dozen codes for the color black, for example, all ascribed to the same product, can be organized into a consistent view.

You could assume your data is in great shape and migrate it as is -- but you miss this MDM chance to centralize data. MDM lets you create what's called an enterprise data layer. Data in the cloud is a post-MPE strategy. You won't employ the cloud unless you're leaving 3000 apps behind.

At the moment there's no announced solution to host an MPE/iX app at a cloud provider. The general manager of Stromasys, Bill Driest, said in May the company wants to develop such a combination for its CHARON emulator, but so far it's still under consideration. Unannounced products are rich with potential for speculation. However, one reason a product doesn't go into development is because no customer wants to become the test case for the first release.

We've already heard that a New York-based financial services company wants offsite emulation for a disaster recovery option using an emulator. They'll probably be employing a co-location supplier, one that will rack a PC configured for the CHARON emulator. Believe it or not, there's data migration to be done in that instance, too. Hot-switch DR needs data at both locations, updated in real time snychronization.

Data movement tools have been on offer for the the 3000 manager for decades. They will be an essential part of any migration or transition, even to a cloud solution.
