Introduced by Code Wizards
Code Wizards simply introduced it has run, to the most effective of their information, the biggest and most profitable public scale check of a commercially out there backend within the video games business. The information comes on the heels of the general public launch of scale check outcomes for Nakama working on Heroic Cloud. They examined throughout three workload situations, and hit 2,000,000 concurrently related customers (CCU) with no points, each time. They might have gone larger, says Martin Thomas, CTO, Code Wizards Group.
“We’re completely thrilled with the outcomes. Hitting 2 million CCU and not using a hitch is a large milestone, however what’s much more thrilling is realizing that we had the capability to go even additional. This isn’t only a technical win — it’s a game-changer for the complete gaming group. Builders can confidently scale their video games utilizing Nakama — an off-the-shelf product — opening up new prospects for his or her immersive, seamless multiplayer experiences.” Thomas mentioned.
Code Wizards is devoted to serving to sport firms construct nice video games on stable backend infrastructure. They partnered with Heroic Labs to assist purchasers migrate away from unreliable or overly costly backend options, construct social and aggressive experiences into their video games, and implement dwell operations methods to develop their video games. Heroic Labs developed Nakama, an open-source sport server for constructing on-line multiplayer video games in Unity, Unreal Engine, Godot, C++ customized engines and extra with many profitable sport launches from Zynga to Paradox Interactive. The server is agnostic to gadget, platform and sport style, powering all the things from first individual shooters and grand technique titles on PC/Console to Match 3 and Merge video games on cellular.
“Code Wizards has quite a lot of expertise benching AAA video games with each in-house and exterior backends,” Thomas says.
It conducts these exams utilizing Artillery in collaboration with Amazon Net Companies (AWS), utilizing plenty of choices together with AWS Fargate and Amazon Aurora. Nakama on Heroic Cloud was equally examined utilizing AWS working on Amazon EC2, Amazon EKS and Amazon RDS, and suits proper into AWS’s elastic {hardware} scale out mannequin.
Mimicking real-life utilization
To make sure the platform was examined totally, three distinct situations have been utilized, every with rising complexity to finally mimic actual life utilization underneath load. The primary situation was designed to show the platform can simply scale to the goal CCU. The second pushed payloads of various sizes all through the ecosystem, reflecting realtime consumer interplay, with out stress or pressure. And the third replicated consumer interactions with the metagame options inside the platform itself. Every situation ran for 4 hours and between every check the database was restored to an entire clear restore with current knowledge, making certain constant and truthful check runs.
A better take a look at testing and outcomes
State of affairs 1: Fundamental stability at scale
Goal
To attain primary soak testing of the platform, proving 2M CCU was attainable whereas offering baseline outcomes for the opposite situations to match towards.
Setup
- 82 AWS Fargate nodes every with 4 CPUs
- 25,000 purchasers on every employee node
- 2M CCU ramp achieved over 50 minutes
- Every shopper carried out the next widespread actions:
- Established a realtime socket
- State of affairs particular actions:
- Carried out heartbeat “maintain alive” actions utilizing customary socket ping / pong messaging
End result
Success establishing the baseline for future situations. Prime stage output included:
- 2,050,000 employee purchasers efficiently related
- 683 new accounts per second created – simulating a big scale sport launch
- 0% error price throughout shopper staff and server processes – together with no authentication errors, and no dropped connections.

State of affairs 2: Realtime throughput
Goal
Aiming to show that underneath variable load the Nakama ecosystem will scale as required, this situation took the baseline setup from State of affairs 1 and prolonged the load throughout the property by including a extra intensive realtime messaging workload. For every shopper message despatched, many purchasers would obtain these messages, mirroring the usual message fanout in realtime methods.
Setup
- 101 AWS Fargate nodes every with 8 CPUs
- 20,000 purchasers on every employee node
- 2M CCU ramp achieved over 50 minutes
- Every shopper carried out the widespread actions then:
- Joined one in every of 400,000 chat channels
- Sends randomly generated 10-100 byte chat messages at a randomized interval between 10 and 20 seconds
End result
One other profitable run, proving the capability to scale with load. It culminated within the following prime line metrics:
- 2,020,000 employee purchasers efficiently related
- 1.93 Billion messages despatched, at a peak common price of 44,700 messages per second
- 11.33 billion messages acquired, with a peak common price of 270,335 messages per second

Notice
As might be seen within the graph above, an Artillery metrics recording difficulty (as seen on GitHub) led to a misplaced knowledge level close to the tip of the ramp up, however didn’t seem to current a difficulty for the rest of the situation.
State of affairs 3: Mixed workload
Goal
Aiming to show the Nakama ecosystem performs at scale underneath workloads which can be primarily database sure. To attain this, each interplay from a shopper on this situation carried out a database write.
Setup
- 67 AWS Fargate nodes every with 16 CPUs
- 30,000 purchasers on every employee node
- 2M CCU ramp achieved over 50 minutes
- As a part of the authentication course of on this situation, the server units up a brand new pockets and stock for every consumer containing 1,000,000 cash and 1,000,000 gadgets
- Every shopper carried out the widespread actions then
- Carry out one in every of two server capabilities at a random interval between 60-120 seconds. Both
- Spend a few of the cash from their pockets
- Grant an merchandise to their stock
- Carry out one in every of two server capabilities at a random interval between 60-120 seconds. Both
End result
Altering the payload constructions to database sure made no distinction because the Nakama cluster simply dealt with the construction as anticipated, with very encouraging ninety fifth percentile outcomes:
- As soon as totally ramped up, purchasers sustained a top-end workload of twenty-two,300 requests per second, with no important variation.
- Server requests 95% (0.95p) of processing instances remained beneath 26.7ms for the complete situation window, with no sudden spikes at any level.
