Hybrid or cloud: How to make the right choice

Share this post:

Nowadays, it’s very common for the CTO or CIO of a company to think about moving an on-premise solution to cloud.  Of course, there are also many questions involved:

  • What are the options?
  • Which option best fits my needs?
  • How do I make sure all the information/content will be migrated?

Let’s take the example of an IBM Domino client deciding on moving their email solution to cloud. IBM has a SaaS-based solution called IBM SmartCloud for Social Business.

The first decision is to choose which scenario will be adopted. For this, we have to discuss  the options and consider some of the following questions:

    • Does the customer have IBM Domino administration skills?
    • Does the customer have applications running on IBM Domino?
    • Does the customer want to keep some on-premises servers?
    • Does the customer need some users (for example, VIPs) to remain on-premises and others move to cloud?

If the questions above were answered with yes,  then the best solution may be  a hybrid environment (cloud plus on-premises), where some pieces of the solution will still be in the company (on-premises), leveraging the current environment and investment in existing Domino architecture. Other services will be hosted in the cloud.

If the questions above were answered with no the best solution may be a  cloud-based environment, where all the email systems would be hosted.

In the service-only environment, the administration is performed using a web browser user interface. Company administrators don’t need to have a a lot of skill in mail systems and the company doesn’t need to take care of the infrastructure where the system is running.

In the hybrid environment, it’s possible to have a flexible administration model, where the administrator person will have more control using administration tools ( Domino Administrator Client and Domino Directory). For example, the administrator can choose if the email account will exist on-premises or in cloud, or to define the management (creation or deletion) of users and groups, as well as whether it will be performed as before in the on-premises environment.

From a  user perspective, they can’t tell if they’re accessing their email from a local system or from a cloud system.

After this decision, for the migration data (email), the companies have some alternatives regarding the migration process.  They can use business partner assets/solutions or use IBM offerings to move the data, but we will discuss this topic in another post.
