How do you compare Atlassian Data Center vs Server – what makes them different and how can you tell which one is right for you? Well, to give you some background, in addition to Server and Cloud versions of\u00a0Confluence<\/a>,\u00a0Bitbucket<\/a>,\u00a0Jira Service Desk<\/a>, and\u00a0Jira Software<\/a>, Atlassian also offers Data Center deployments. Data Center is a type of self-hosted deployment. The primary difference on a technical level in a comparison between Data Center vs Server is that Data Center permits multiple application servers running in parallel. Server only permits one application server. We are often asked by customers about\u00a0Atlassian Data Center<\/a>\u00a0vs Server \u2013 and which option specifically is right for them.<\/p>

\u00a0<\/p>

In this post, we will explore the differences between Server and Data Center and provide you with ways to determine which best meets your needs. In short, the answer depends on the size of the deployment and its business importance.<\/span><\/p>

The benefits of Atlassian Data Center<\/strong><\/h3>

\u00a0<\/p>

Atlassian Data Center is designed for large-scale, mission-critical deployments. It costs more than Server, but it provides high availability, performance at scale, deployment flexibility and zero-downtime upgrades.<\/p>

\u00a0<\/p>

What do these benefits mean?<\/p>

\u00a0<\/p>

Performance at scale:<\/strong>\u00a0Atlassian Data Center permits multiple application servers, so for a given specification of server, an instance of Data Center can handle more users than one of Server. Data Center instances can be built which spin up or shut down application servers with fluctuations in demand, which is known as autoscaling.<\/p>

\u00a0<\/p>

High availability:<\/strong>\u00a0Due to multiple application servers, if one were to fail, the others would keep the service running. Server has only one application server; if it fails, the whole application would go down.<\/p>

\u00a0<\/p>

Deployment flexibility:<\/strong>\u00a0Atlassian has developed templates for building complete autoscaling instances of Jira Data Center and Confluence Data Center in Amazon Web Services (AWS) and Microsoft Azure. The templates within Jira Data Center and Confluence Data Center (called \u2018Quickstarts\u2019 in AWS) enable you to create, within minutes, all the required application and database servers, with configurations and ancillary components (such as load balancers) for a complete instance of Data Center.<\/p>

\u00a0<\/p>

Zero-downtime upgrades:<\/strong>\u00a0Data Center allows you to upgrade the version of your Atlassian application without taking the system offline. The upgrade is performed one server at a time. While one server is being upgraded, the others keep the service (e.g. Jira) running. A self-hosted Atlassian application normally requires at least one version upgrade per year in order to stay current. The more expensive downtime is for your organisation, the more valuable zero-downtime upgrades are.<\/p>

Factors to consider<\/b><\/h3>
NB: Atlassian Server has a fixed life remaining in terms of how much longer it will be offered as a solution for Atlassian products. By February 2024 all Server users will need to have transitioned to either Data Center or Cloud. It’s worth bearing this in mind when you consider the longevity of the solution you’re searching for.<\/span>

\u00a0<\/p>

In choosing between Atlassian Data Center vs Server, the main factor is often the additional cost of Data Center versus the additional cost of the outages it would prevent. A secondary factor is whether the required performance can be delivered with a single server. Downtime becomes more of a problem the larger an organisation becomes. Server outage can be caused by something as simple as a lack of processing power, storage or memory. But an hour of Jira downtime, for example, could have significant financial and operational consequences.<\/p>

\u00a0<\/p>

Atlassian Data Center costs more than the Server product, but when the cost of the average downtime in a year approaches the additional cost of Data Center, or the volume of users is beginning to affect performance, that is the time to consider moving to Data Center.<\/p>

\u00a0<\/p>

The point at which organisations choose to move to Data Center varies. According to Atlassian, 45% of current Data Center customers have moved from Server to Data Center at the 500 or 1,000 user tiers \u2013 but this can vary from product to product. For Jira Service Desk, for example,\u00a0Atlassian<\/a>\u00a0found that 50% of Data Center customers upgraded when they reached 50 users.<\/p>

The cost of downtime<\/strong><\/h3>

\u00a0<\/p>

Do you know what an hour of downtime costs you?<\/p>

\u00a0<\/p>

You can normally work it out by counting how many of your employees rely on Atlassian products to get their jobs done. If there was an outage, their productivity would decrease, and an estimate can normally be made from there.<\/p>

\u00a0<\/p>

The cost of your employees\u2019 lost time gives a minimum to the cost of an outage. The true cost may well be higher, because of such factors as:<\/p>
