moving from cloud to on-prem
Asked by Packiaraj Dhandapani:

Hi, we have cloud subscription for 300 seats and we acquired new company and they also running JIRA cloud instance.

we wanted to merge the accounts into one and need to increase 100 more seats. When we compare the prices between cloud and on-prem seems to be a best bet for us.

We have users across the globe and have a dedicated MPLS lines to all the sites.

if we want to go for an on-prem server, should we go for the standalone server or cluster mode and why.

Also our current sign-in method is SSO through Azure. how do we achieve the SSO with on-prem

We do have quite a bit of material written to help you decide if Jira Server or Jira Data Center (what you mentioned as cluster mode) are right for you. [Here's a great intro blog post on the topic](https://www.atlassian.com/blog/jira-software/server-vs-data-center-whats-right). If you'd like a full feature comparison between Jira Server and Jira Data Center, [we've got that too](https://confluence.atlassian.com/enterprise/jira-server-and-data-center-feature-comparison-953651628.html).

Since you mentioned you've got Azure and SSO, I'll quickly go over some reasons you might consider Data Center based on the info you provided:

1. Data Center comes with **Atlassian-supported SAML** capabilities (for SSO). You can get this on Server, but only through [separately-licensed third party plugins](https://marketplace.atlassian.com/search?hosting=server&product=jira&query=saml).
2. **Deployment templates** for Azure are available for Data Center. You mentioned you are thinking about running on-prem, but you may also consider using the Azure templates for easy set-up since you're currently having us run all your infrastructure in Jira Cloud.
3. **Zero downtime upgrades** are a killer feature for admins (and for your users since there's no downtime!) that help ensure you can keep working while installing upgrades.

Our instructions for [configuring SSO with Jira Data Center are here](https://confluence.atlassian.com/enterprise/saml-single-sign-on-for-atlassian-data-center-applications-857050705.html). If you opt for Jira Server and use a plugin, the instructions vary by the plugin you select. Each plugin page should have information on how to get started.

Hope that helps!  
Daniel

body: Hi Daniel, Thanks for your response. i got some idea between the Jira Server and Data center. Looks like we may plan the Jira Server. Can we use ADFS for our single sign-on ?
