Preface

With the popularity of the game market, the game industry is gradually moving towards a pattern of boutique, IP and diversification, which also puts forward higher requirements for game developers. How to ensure the stable performance of the game and provide players with a smooth gang up experience? This double 11, ready to try to use Huawei Cloud services, immersive feel the power of the game cloud deployment solution.

1. Introduction of game architecture

1.1 Server Architecture

Different companies have different game server architectures, so the details of deployment are mostly different, but the basic deployment preparation is still the same. Take a look at our game architecture first to facilitate readers to understand the follow-up preparations.

1.1.1 specific introduction to server roles

Client: game client.

Gate: gateway service, which does not carry the link of the game, but only distributes the address of the game server. Players get the ip and port of the official game server from the gate server.

Game: there is only one main game server for players.

Room: room service. Players will enter the combat suit after entering the battle. If you fight more, you can do dynamic expansion.

Gm: background management server, which can publish events or manage player data.

Redis: mainly used for caching to avoid frequent database access pressure.

Mysql: mainly used for data persistence.

1.1.2 player data flow

Players (client) access the gate server through http to obtain the ip and port of the game service.

Client connects directly to the game server through the ip and the port, so the player can log in to the server.

When the player operates the character to match the battle, after the match is successful, the required data will be passed to the room server, and all battle instructions will be passed to the room service.

When players need to query data, such as to obtain a backpack, game server will first query like redis, if the data does not exist, like mysql query, the data will be stored in the cache after query.

When the player's character data changes, such as getting a new prop, you need to manipulate the database. The game server will update the database first and then update the cache.

Use gm when posting activities and modifying player data, by issuing instructions to the game server.

1.1.3 Inter-service interaction protocol

Http protocol: mainly occurs in places with few access scenarios, between client and gate,game and Gm.

Dubbo protocol: mainly used to exchange data between internal servers, simple and direct, just like manipulating local methods.

Webscoket: mainly used between client and game, because this is a web game server, so use websocket.

1.2 deployment mode

There are several reasons for using docker here:

Standardized application release to avoid problems caused by the environment.

Save time, facilitate rapid deployment and startup.

The team students are more familiar with it and reduce the possibility of making mistakes.

2. Deployment preparation

2.1 Environmental preparation

2.1.1 Machine preparation

Make a table statistics on the configuration of the server, as long as the server is ready. The following table is based on Huawei Cloud official website.

Note: the specific price is actually based on the official website price.

2.1.2 solution composition

Elastic CVM ECS: it is a computing service that is self-available and scalable on the cloud at any time, which helps to create a secure, reliable, flexible and efficient application environment.

Elastic load balancer ELB: automatically distributes access traffic to multiple CVMs to expand the external service capability of the application system and achieve a higher level of application fault tolerance.

Cloud database RDS for MySQL: it has the characteristics of ready-to-use, stable and reliable, safe operation, flexible scalability, easy management, economy and practicality, which enables customers to pay more attention to business development.

Redis version of distributed caching service: the industry's first Redis cloud service that supports both Arm and x86 architectures, supports dual-machine hot backup HA architecture, and provides standalone, master / slave, Proxy cluster, Cluster cluster, and read-write separation instance types to meet the business needs of high read-write performance scenarios and elastic modification.

Cloud log service LTS: provides one-stop log collection, second search, mass storage, structured processing, dump, visual chart and other features to meet application scenarios such as OPS, web log visual analysis, protection compliance and operation analysis.

DDoS defense AAD: provides global services to deal with DDoS attack challenges, provides millisecond attack response, multi-dimensional behavior analysis and machine learning, automatic tuning of defense strategies, and accurate identification of complex DDoS attacks to protect your business continuity.

Elastic public network IP EIP: elastic public network IP (Elastic IP) provides independent public network IP resources, including public network IP address and public network egress bandwidth service. It can be flexibly bound and unbound with elastic cloud servers, bare metal servers, virtual IP, elastic load balancers, NAT gateways and other resources, providing access to public network and being accessed by public network. Have a variety of flexible billing methods to meet the needs of different business scenarios

Document database service DDS: document database DDS is compatible with MongoDB protocol, and provides one-click deployment, auto expansion, disaster recovery, backup, recovery, monitoring and other service capabilities on the basis of Huawei Cloud's high performance, high availability, high security and self-scalability. Currently, three deployment architectures are supported: sharded cluster (Sharding), replica set (ReplicaSet) and single node (Single).

2.2 Mirror preparation

The image is ready to be packaged and pushed to a private repository. You can use some plug-ins, Jenkins, or manual push. Either way, prepare the manual commands that may be needed.

2.2.1 install the docker service

2.2.2 package Image

Copy the jar package to the same directory as dockerfile and execute the following command to package the image.

2.2.3 package the image as a local file

The image is exported as a compressed package, which is convenient for transmission.

2.2.4 unpack the image

After logging in to the server, copy the above file to the local machine and import the image to the current machine using the following command

2.3 deployment script

Note: the above is the development environment, and some environment variables are default, which need to be adjusted dynamically when the formal environment is deployed.

2.4 pay attention.

The gate server needs to activate public network ip.

The excel configuration file should be planned in advance and mounted in the docker script.

The data directory and log directory mounted by docker need to be planned in advance.

The port mapping within each server should be planned in advance.

The environment variables need to be modified in the script, including the mysql and redis database addresses, the server ip and port that need to be linked, and the relevant server configuration.

3. Formal deployment

3.1 Environmental investigation

Game pain points:

New games start, a large number of players are online, and the expansion of high concurrent access is not timely.

The network delay is high, the game stutters and the player is offline.

The self-built cycle is long and the cost is high, so it can not stretch flexibly.

Most game servers are computationally intensive, so game server cloud vendors choose the following core points:

The capacity of resource expansion can be expanded in time, and resources can be purchased flexibly according to demand, so as to achieve dynamic expansion and cost optimization, and support business operation in scenarios such as game launch, expansion, and service.

The computing power is excellent, and the same type of ECS is 15% higher than the competitor. The container is released quickly, and the performance is 20% higher than that of open source. BMS can be released in 5 minutes.
