The document describes the architecture of an MMO game called Happy Me. It discusses three key parts of the architecture: an object management system using MVC design, an automatic synchronization framework between server and client, and a custom network message dispatching system. The architecture provides a seamless MVC framework across server and client and addresses common challenges in synchronization for active server games. It also allows the game to easily scale on AWS infrastructure.

A presentation done for my Oral Presentation Skills course. I got the maximum scores for it thus my course is practically done with the best possible mark too :D Again, the explanations and text was said and not included in the slideshow but you still might enjoy the screenshots taken from several games ;) -Qvi

This document provides a high-level introduction to the technology involved in massively multiplayer online (MMO) games. It discusses IBM's role in gaming and provides an overview of MMO architecture patterns, components, and growth considerations. Key systems like economic, game, and support organs are examined at a basic level. Factors like upfront and ongoing costs, user base sizing, and infrastructure scaling are also addressed. The future of MMOs is speculated to include more genres, platforms, user-generated content, and global free-to-play models.

This document discusses the development of a prototype virtual world distributed server in Erlang to analyze the needs of massively multiplayer online game servers. It describes some key problems for MMOG servers, how Erlang was used to quickly prototype solutions, and tests conducted on architectures with different node configurations. The tests aimed to determine the maximum supported number of players and identify issues causing desynchronization between clients and servers. The prototype was found to be effective for rapidly exploring algorithms and architectures for distributed MMOG systems.

Presentation on MMOG architecture given to several app development groups interested in moving into the game design world. Much of this content was inspired by t-machine.org.

Mobile applications nowadays are developed either for a local (native) or for a client-server execution. However, applications in the future will be developed with cloud in mind, i.e. act as native applications, but do the heavy processing and storage in the cloud, deliver only needed parts and data at runtime and able to run offline. In order to better understand how to facilitate the building of mobile cloud-based applications, we have surveyed existing work in mobile computing through the prism of cloud computing principles. We provide an overview of the results from this survey, in particular, models of mobile cloud applications. We also highlight research challenges in the area of mobile cloud computing.

This document summarizes an architecture for a multiplayer online game. It includes three main systems: an object management system to organize game data, an auto synchronization framework to keep server and client data in sync, and a network message dispatching system for server-client communication. It was developed over 12 months by a team of 3 system developers and 4 game developers to support a room-based social game with a web-based Unity3D client.

- Social networks in MMOs can be defined as the social structures and relationships that develop between players through gameplay and interaction tools. They often resemble real-world social networks. - EVE Online exemplifies how robust social networks form in MMOs. Players organize into corporations and alliances that may include thousands of members and function similarly to companies and nations. Communication tools are essential for coordination. - As player groups grow larger, game designers must consider how to support emerging leadership roles and social hierarchies to ensure networks remain fun and don't disrupt new player experiences. The lines between MMOs and social media will continue to blur as virtual communities deepen.

Online gaming is one of the most profitable businesses on the Internet. Of all the genres of online games, MMORPGs (Massive Multiplayer Online Role Playing Games) have become the most popular among network gamers, and now attract millions of users who play in an evolving virtual world simultaneously over the Internet. To gain a better understanding of game traffic and contribute to the economic well-being of the Internet, we analyze a 1, 356-million-packet trace from a sizeable MMORPG called ShenZhou Online. This work is, as far as we know, the first formal analysis of MMORPG server traces. We find that MMORPG and FPS (First-Person Shooting) games are similar in that they both generate small packets and require low bandwidths. In practice, the bandwidth requirement of MMORPGs is the lower of the two due to less real-time game playing. More distinctive features are the strong periodicity, temporal locality, irregularity, and self-similarity observed in MMORPG traffic. The periodicity is due to a common practice in game implementation, where game state updates are accumulated within a fixed time window before transmission. The temporal locality in game traffic is largely due to the game’s nature, whereby one action leads to another. The irregularity, which is unique to MMORPG traffic, is due to the diversity of the game’s design so that the behavior of users can vary drastically, depending on the quest at hand. The self-similarity of the aggregate traffic is due to the heavy-tailed active/idle activities of individual players. Moreover, we show that the arrival of game sessions within one hour can be modelled by a Poisson model, while the duration of game sessions is heavy-tailed.

In this session, AWS shares best practices for mobile, console, and MMO games that can scale from 1,000 to 1,000,000 users. See how to create a game backend using Amazon EC2 and AWS Elastic Beanstalk. Learn about database scaling challenges, and how to use Amazon DynamoDB and Amazon ElastiCache to address them. And, hear how to deliver game assets efficiently using Amazon S3 and Amazon CloudFront. Then, hear from Roope Kangas, Lead Server Developer and co-founder at Grand Cru, about their journey launching and cost-optimizing Supernauts on AWS. Grand Cru used load testing to validate their system before launch, enabling them to reach 1 million users in 6 days. Then, after launch, the team optimized their architecture based on system metrics to cut their AWS costs by more than half.

This document describes the architecture of an MMO casual game. It has a room-based active server architecture with a web-based Unity3D client. It uses three main systems: an object management system, a server-client data synchronization framework, and a network message dispatching system. The object management system uses an MVC pattern to manage game objects in a single system. The auto synchronization framework automatically synchronizes property changes between the server and clients. The network message dispatching system allows easy registration and handling of custom structured messages.
