On-premise vs. infrastructure as a service

One of the benefits of Atlassian's Data Center products is infra- structure choice. You can deploy on-premise or with infrastruc- ture as a service (IaaS) vendors like AWS and Azure to best suit your company's existing investments. In fact, more and more customers are choosing to deploy Atlassian tools using IaaS providers: 62% of Atlassian’s self-managed customers are choosing to deploy their applications on a virtual architecture.

Consider which option is better for your organization, and read more about your Atlassian products and IaaS on our blog.

Review your disaster recovery strategy

Partial or complete system outage? Avoid chaos and keep business running smoothly with a disaster recovery strategy. With disaster recovery for Atlassian's Data Center products, you can configure index replication, attachment updates, and database synchronization to comply with your DR plan's specific requirements.

No two disaster recovery plans are exactly alike. Learn how to use Confluence Data Center to implement and manage a disas- ter recovery strategy for Confluence in our documentation.
