Migrating Your Messaging Infrastructure to the Cloud
Migrating your messaging infrastructure to the cloud
As you can see, these five items are highly interrelated and interdependent. Enterprises can use the following checklist-which includes business requirements and examples I've recently observed-when considering the move to cloud computing.
1. Outsourcing the External Gateway Filtering Layer
Compare the bandwidth and infrastructure costs to the service and support costs. What security sacrifices need to be made to put mail cleansing in the cloud? What complex policies exist internally today that cannot be done in the cloud?
2. Outsourcing the Groupware Layer
What is your comfort level with enterprise data being stored externally? Can your data retention and archiving needs be met and guaranteed? How does existing data get migrated?
3. Outsourcing the E-mail Backbone Layer
Is this achievable for your enterprise? Are you comfortable with not only the data exposure but the lack of control in doing so?
In the end, who is responsible for your e-mail? Think about your own messaging infrastructure. If you use cloud services or are considering a move to the cloud, it's important to understand that. While the promises of cloud computing can be potentially realized by migrating different layers of the messaging infrastructure to the cloud, it's also critical to address the risks involved.
