Key Aspects of Jira Data Center

Built for enterprise products that are autonomous or self-managing, Data Center is used to meet unique organizational needs for those that have flexibility in choices of infrastructure and controls. 

Now you can modernize your IT infrastructure without compromising on security and control. Data Center is equipped with built-in features to meet complex demands and combines the powerful tools of Jira service management and software by supporting them with the following properties. 

High availability

Active clustering of critical applications ensures uninterrupted access to all users. In the event of unexpected hardware failure, it uses industry-standard shared file systems, load balancing, and database clustering to minimize downtime.

Performance at scale

Nodes are added to the Data Center clusters to increase the concurrency of user capacity and improve the response rate in growing user activity.


Jira Data Center is made up of a chunk of dedicated and connected machines demonstrated in the figure below.

Jira Network and Load Balancer With Cluster Nodes

Once the connection is established, the network is then connected to the load balancer. Under load balancer comes a cluster of nodes that are connected to the shared file system and database.

Load Balancer

The load balancer handles the distribution of requests from the user to the cluster nodes. The critical reason for use is that it detects the failure when the cluster node is down. Within seconds, it automatically directs the requests to other present nodes and ensures data flow efficiency. Any load balancer can be used, but it must support session affinity.

Application Nodes

In nodes of DS, the cluster shares the workload of new or incoming requests. Upon failure of a cluster node, the requests are directed to the other nodes causing virtually no loss of user availability.

Shared database and Storage

Jira Server and Data Center support the same databases. Notable database configurations are Amazon RDS Multi-AZ and Amazon PostgreSQL-Compatible Aurora

Shared file systems are also supported by Data Center and include the following:

  • Plugins
  • Shared caches
  • Import/export files
  • Logo director
  • Any type of data directory that includes the avatars, attachments, and icons

Key Aspects of Jira Cloud

Available for software houses, teams, and developers, Jira Cloud offers high-quality developer tool integrations with features predominantly required for acrobatic software development.

Jira Cloud allows IT companies to leverage their economies of scale, but in addition, provides security, encryption, and performance that would not be possible with on-premises infrastructure budgets.

The Jira Cloud server infrastructure is designed for reliability and optimal performance with failover options and redundancy worldwide. Cloud products are built to take rapid actions on increased customer load and data. This provides predictable and consistent performance that spreads the business on a larger scale and meets customers’ needs. 

Jira Cloud provides product-specific security practices and utilizes high-performance vulnerability scanners to monitor network security of external and internal infrastructure.

Additionally, the Cloud team employs high-tech security consulting firms for security testing on overall infrastructures and high-risk products. Data encryption is completed automatically in transmission/distribution, ensuring reliable availability by guarding against service interruptions and unauthorized accesses. 

Since it is based on Atlassian shared accounts,  users with one account have access to Jira products, bitbucket, and confluence. Software application and single database is shared among customers, but each customer’s data is isolated and inaccessible to other customers. The result is increased customer scalability and availability.

Atlassian leverages a wide number of techniques to achieve high performance in Cloud architecture. These techniques include: 

Global distribution

Because the Cloud is global, customers’ content is closer to end-users, optimizing the performance of users based on the highest traffic location.

Dedicated internal networks

Users are connected to the Cloud via a private dedicated internal network that is nearest to them. This speeds up the connections and runs a smoother user experience.

Content Delivery Networks and caching

Cloud automatically caches the frequently accessed content delivery network to rapidly deliver static content that is common across multiple users.

Breaking down of differences between Jira Data Center vs Jira Cloud

Deployment and administration

In the Jira Cloud, Jira Support hosts, sets up, maintains, and secures the Atlassian site in the Cloud. This requires less administration for installation and configuration on the Cloud.

Conversely, in Data Center, customers are required to host Atlassian products on local hardware or through Cloud hosting services like Amazon Web Services. Users have full control over the database, which means complete authority over administration and customization. 


Because Atlassian manages product upgrades automatically, there is no need for manual upgrades in the Jira Cloud. Users receive immediate access to updated features with security features being a primary beneficiary of this process.

In Jira Center, the administrator is responsible for manually upgrading products upon the release of a new version. Consequently, the administrator is tasked with scheduling, maintaining, and implementing software upgrades.

User management

In Jira Cloud, user accounts are centrally managed through the organization rather than product by product. Access allows you to manage authentication and security policies and offers better affordability to manage user accounts.

In the Data Center, server admins can address user management in various ways. It can be accomplished through Jira by connecting to Atlassian Crowd or on a product-by-product basis.


Backups are generated daily and retained in the server for a maximum of 30 days in the Cloud.

The administrator has to go through a complex process to set up the backup and the admin is solely responsible for maintaining it.

Direct Access to the database

In Jira Cloud, the user does not have direct access to modify the file system, database structure, or other server infrastructure. However, certain extensive REST APIs are provided to access the data.

In the Jira Data Center, the admin is given full access to the database directly.

Mobile Apps

Jira Cloud apps and confluence apps are offered to all Cloud customers for secure and fast collaboration without setting up a VPN.

In Jira Data Centers, if the instance is public and it does not have a firewall, the user will first have to connect to the organization’s VPN to access the products. 

User limit

  • Individual Cloud product support up to 10,000 users
  • In Jira Data Center, there is no certain limit for the users

While there are critical differences between the Jira Data Center and the Jira Cloud, choosing between the two should depend on specific organization’s needs and usage. Check out this blog for a more visual breakdown of how to run Atlassian and in what situations each makes the most sense.
