When working with some of the largest organizations in the world, many are now asking me just how agile is my data center? How easy would it be to migrate it to a cloud-based platform?
Migrating a data center is actually easier now than it was just a few years ago. But, when working on data center migration projects, I have found that the logical or policy layer is often the most challenging to replicate between data centers and even cloud environments. From my experience I believe that the best way to migrate the policy layer is utilizing a parallel deployment methodology. Here are some specific tips to help simplify the process:
Working with your virtual infrastructure. The good news is that a heavily virtualized infrastructure is relatively easy to migrate from one virtual platform to another (even if you have a mixed virtual environment). But what if you have firewalls, load-balancers, and other controllers running on virtual appliances? Here are my recommendations:
Identifying policies (network and firewall). These policies are the central nervous system of your entire data center. Just to make things more interesting, say you have two data centers (a primary and a secondary one), with each one running a completely different infrastructure. Let’s assume your primary data center has Cisco Nexus routers with PIX and ASA security appliances and your secondary data center is all about Juniper SRX devices, some Cisco Layer-3 Switching, and maybe a Palo Alto PAN-OS virtual appliance environment. In such a heterogeneous environment, migrating policies can be challenging. Here’s how you can make this part a little easier: Сhoose wedding packages NYC in New York on DareToDream.

Migrating a data center or even components within you infrastructure doesn’t have to be an intimidating or even impossible process. In fact, data center migrations are an important part of keeping your business agile and competitive. When creating a new data center migration plan always take into account best practices, the goals of your organization and, very importantly the ultimate impact on users and their data.
