Moving to the cloud offers many advantages as opposed to staying on premise.

• Anywhere access to your Atlassian tools, without exposing your internal infrastructure.
• Availability is no longer your responsibility.
• Cost efficiency: you only pay for what you use and not for what you possibly may need in the future.

Running Atlassian products in a private AWS cloud offers significant advantages:

• Complete control over environment performance and availability, with the ability to scale as needed.
• Limitless integration with internal tools and systems.
• Access to all Data Center apps from the Atlassian Marketplace.

The benefits of multiple nodes versus a single node include:

• Better performance through load distribution across nodes.
• Zero downtime upgrades. Upgrade in place without disrupting end-users.
• Flexibility for maintenance and system/application updates.
