Azure enables successful global service of MMORPG title Phantasy Star Online 2
In the present day, good games can be played by anyone, regardless of where the Customer Name players are. However, delivering such games to people around the globe without SEGA Corporation changing what makes the game interesting requires overcoming several technical https://www.sega.co.jp challenges. Product or Service Azure In April 2020, SEGA started the service of a massively multiplayer online role- Azure Ultra Disk playing game (MMORPG) named Phantasy Star Online 2 in North America.

Country Selecting the cloud as a foundation to mitigate Japan risk in a game project with flexible sizing
Published in December 2020 SEGA Corporation is a member of SEGA SAMMY Group. This company develops, manufactures, and sells video games, and is known for creating best games in the industry. Phantasy Star Online (PSO2), one of the largest MMORPGs in Japan, is made and run by this company.
PSO2 is an action role-playing game (RPG). In this game, players can enjoy raising their character, communicating with other players, defeating strong enemies, and exploring for valuable items in the world in which science fiction and medieval fantasy are fused together.
The first Phantasy Star was released in 1987, and its sequels have been loved by many all this time. PSO2 is the newest title in the series, with “infinite adventure” as its concept, meaning it has contents that let players keep playing it for a long time. This game has been released for multiple SEGA Corporation platforms. It was launched as a game for Windows PC, and then for Azure Ultra Disk Storage: Enabling PlayStation Vita and subsequentially for PlayStation 4 (PS4). Later, when the game started its service for Nintendo Switch, it did so as a cloud performance without spoiling gaming service. The year 2020 marked the eighth anniversary of this playability game.. Endo explains that the result of researching cloud services of several companies showed none of them could satisfy the required level of PSO2 had been running its service only in Japan. However, according performance. to Hisashi Endo, Technical Director of 2nd Program Section, 2nd Department of CS R&D No.3, 3rd Division at SEGA, the idea of running “PSO2 relies more heavily on a performance of game server than that its service overseas had been on the developer’s mind for a long time. of client terminals, explains Endo. “We conduct on-premises server operation when servers are in Japan, and we tune servers to shorten “Since the game has been well received in Japan, we had wanted to the response time of queries issued to a database to 1 millisecond or expand its service to overseas markets for a long time,” explains Endo. less. If a platform cannot assure both IOPS and throughput at high “The North American market is particularly large among the global level, it spoils the action element of PSO2. During our first research, we markets. However, to run the service overseas, we must overcome had to conclude that none of cloud services could satisfy our needs.” various difficulties, including operation and maintenance of overseas servers and providing user support that fits with local culture. We had “To start the service of PSO2 in North America, it is difficult to adopt a an ambition for expanding our service to overseas, but it required time cloud service as the game foundation.” That was the gist of the report to embody our plan for that.” Endo began to write for his superiors in October 2018. Just around that time, he heard about Microsoft Azure Ultra Disk Storage (formerly One of the largest technical issues was a game server. The company known as Ultra SSD). could borrow a datacenter in a foreign land, but that would require travelling long distances for maintenance work. According to Mitsunori Ultra Disk Storage is a top-tier disk storage on an infrastructure as a Fujimoto, Manager of the Development IT Support Team at SEGA, service (IaaS) virtual machine (VM) provided by Azure. It supports high because of this, the team started to consider using the public cloud. capacity, high IOPS and high throughput, and enables operation of workload with very high IO demand. “At SEGA, we started to use a cloud service for the foundation of our game in 2008, which was a relatively early period in the history of cloud “At that time, Ultra Disk had not been released yet, but members of computing,” explains Fujimoto. “It is quite hard to predict whether a Microsoft Japan negotiated with their headquarters and prepared game will become a hit before releasing it. Compared with on-premises, an environment for us,” recalls Endo. “We immediately checked its cloud computing allows more flexible sizing, so it can mitigate risk in performance and the result was surprising. It was more than equal to the game project.” the performance of the on-premises server tuned for PSO2. It looked promising, and we became so excited. We could not start our service of Thus, the company started to research public clouds to see if any PSO2 in North America without Azure.” of these services could work as a game server of PSO2. During the research, however, it realized the huge difficulty unique to an online It was the first time that Azure was chosen for the foundation of action RPG. consumer service provided by SEGA. However, Fujimoto says with smile that migrating from on-premises to Azure “did not cause any hardship to us..
“It was the first time for us to use Azure on a massive scale, but we actually started that quite smoothly,” notes Fujimoto. “PSO2 had been running on a Windows server, so we had expected that the game would be compatible with Ultra Disk as well, and it was even better than that. Because Ultra Disk showed very high performance, we did not have any trouble in the migration and the tuning. Of course, we found a difference in usability between on-premises server and Ultra Disk, but thankfully, we received immediate support from Microsoft for our technical questions. If I have to speak of any hardship I experienced, it would be that since Ultra Disk was a very popular service, at the start of SEGA Corporation
our using it we had difficulty in securing instances.” concurrent accesses per one world, depending on hardware ability,” explains Endo. “If a number of accesses exceed this maximum number, we need to replace a hardware. However, Ultra Disk has a function to dynamically change setting capacity, IOPS, and throughput. This is why at the time of releasing this game in North America, we could change the setting for the number of concurrent accesses to three times more than that of the Japanese version, without stopping our service. Even after that, we have repeatedly optimized the sizing of the cloud as the number of users increased or decreased̶thus reducing the cost without spoiling our services.”
Release of PSO2 in North America had been anticipated by gamers in the region. When it was announced at Xbox E3 Briefing 2019, audiences became so excited. Using Ultra Disk Storage as the game foundation Handling server accesses three enabled SEGA to provide this game to the users without letting them times more than expected, thus down. living up to fans’ expectations Fujimoto evaluated the operation of Azure with the perspective of administrator. In 2020, PSO2 finally started its service in North America. It was released for Xbox One on April 14, and for Windows PC on May 27. “I had an impression that it is more stable than other cloud services. Even when a failure occurs, it provides us detailed information,” says “Of course, we had done research to see how many players would play Fujimoto. “It reports the cause of a failure very quickly and with details, the game,” says Endo, “but in the end, we would never know until the which helps those of us who operate the cloud service a lot. Also, we game went live. Right after its release in North America, the number of found that Azure has an excellent dashboard. Even when we changed players was three times more than our expectation.” a configuration, it showed us clearly the cost, such as ‘How much is the price related to this project?’ This kind of usability for administrators should be advertised more by Microsoft salespeople.”
“When I first heard the explanation about it,” recalls Fujimoto, “I thought that the pricing plans were too complicated and proposed prices were not cheap at all. I began not liking it, and even thought that ‘I would never use this service’. However, as I heard more about it, I gradually started to think ‘this may be good, after all’.”
Fujimoto continues about why his impression was changed.
“The biggest reason was the salespeople,” Fujimoto continues. “They often visited us and repeatedly made explanations and proposals. People from Microsoft did not finish their explanation with ‘We are sorry, but we have to follow the decisions made by headquarters’, and instead responded to our requests flexibly as a provider of enterprise computing products. I started with the worst impression of your service, Endo continued, saying that because of the functions of Ultra Disk but ended up introducing it to our product. Isn’t that like a romance Storage, the company could handle this unexpected number of drama, with marriage as the final episode?” accesses flexibly.
“The Japanese version of the game, which is run with on-premises operation of the server, is designed to limit the maximum number of SEGA Corporation
we aim to release it in not only Japan and North America, but countries around the world as well. To handle this kind of huge project, I will need to learn more about how to operate Azure.”
SEGA became the first company to adopt Ultra Disk Storage in the video game industry, and succeeded in releasing widely in the game world-. In 2020, the company celebrated its 60th anniversary since its foundation, and it will continue providing innovative content to the world.

In July 2020, a Microsoft online conference called “Xbox Games Showcase” was streamed, and during the streaming, it was revealed that PSO2 will evolve even further.
Endo concludes, “In 2021, we will start Phantasy Star Online 2: New Genesis, which is the l updated version of PSO2. It is the newest one in the series with a renewed game system and graphics engine. Of course,
