There are multiple reasons a growing number of database administrators, enterprise architects, application developers and other technology practitioners are moving to Google Cloud’s various database services.

Some are being driven by missing features in offering from other providers such as AWS. In Gartner’s Magic Quadrant for Operational Database Management Systems, the research and advisory firm points out that, “AWS’s surveyed reference customers scored its overall product capabilities one standard deviation (STD) below the mean. Their responses identified missing features such as multiregion writes and autosharding.”

Others are moving to database services on Google Cloud Platform driven by a few benefits. According to Gartner, “Reference customers repeatedly commented on Google’s ease of use and implementation, reliability and integration (with other services and other systems). Reference customers scored Google a full STD above the mean for satisfaction with GCP’s pricing; it received the second-highest satisfaction score of any vendor in this Magic Quadrant.

If you are looking to leverage the power of Google Cloud database offerings—but were unsure of which database services comes closest to the service you are currently using, here’s a handy map to find your way.

Traditionally, dedicated game servers for real time multiplayer games have used bespoke UDP protocols for communication and synchronization of gameplay among the players within a game. This communication is most often bundled into monolithic game servers and clients, pairing the technical functionality of communication protocols, such as custom network physics synchronisation, security, access control, telemetry and metrics, with the extremely high computational requirements of physics simulations, AI computation and more.

Developed in collaboration with Embark Studios, Quilkin is a UDP proxy, tailor-made for high performance real-time multiplayer games. Its aim is twofold:

1. Pull common functionality, such as security, access control, telemetry and metrics out of monolithic dedicated game servers and clients.
2. Provide this common functionality in a composable and configurable way, such that it can be reused across a wide set of multiplayer games.

This reusable foundation then allows game developers to spend more of their time focusing on building the game-specific aspects of building their multiplayer communication protocols, rather than these common aspects.

Challenges with multiplayer Game Server communication

In fast-paced, multiplayer games, the full simulation of a session of gameplay generally occurs within the memory of a monolithic dedicated game server, whose responsibility covers everything from network physics and AI simulation to communications from client back to server and more.

Since the entire state of the game is memory resident, each client connects directly to the dedicated game server the player is playing on, which presents several challenges:

• Each dedicated game server is a single point of failure. If it goes down, then the whole game session (or sometimes multiple sessions) fails. This makes it a target for malicious actors.
• The IP and port of connection to the game server is public, and exposed to the game client, making it easy to discover and target.
• Multiple aspects of game server simulation and network communication are tightly coupled in the same process, making reuse and modularity more difficult, and expanding risk of performance issues.

If we look at both web and mobile technologies over the past several years, some of these challenges start to look very familiar. Thankfully, one of the solutions to help drive dedicated server workloads to more redundant and distributed orchestration is the utilisation of traffic proxies!

By using a proxy for multiplayer UDP traffic, in front of our dedicated games servers within a low latency network such as what is available on Google Cloud, we can address these key challenges as follows:

• Greater reliability. Proxies provide redundant points of communication entry. UDP packets can be sent to any number of proxies and routed to the dedicated game server. While a dedicated game server will still generally be a single point of failure, proxies improve redundancy and potential failover at the communication layer.
• Greater security. The IP and port of the dedicated game server is no longer public. Game clients may only have visibility into a subset of the proxy pool, limiting a potential attack surface.
• Greater scalability. We start to break apart the single process, as we can move aspects of the communication protocol, metrics, communication security and access control into the proxy. This removes the non-game specific computation out of your game server’s processing loop.

As a result, the entire system is now more resilient as proxies can be scaled independently, not only for performance reasons but also to distribute load in case of malicious actors.

Introducing Quilkin: The UDP proxy for Game Servers

Embark Studios and Google Cloud came together and built Quilkin, to provide a standard, open source solution.  Based out of Stockholm, Embark Studios is a (relatively) new studio made up of seasoned industry veterans.  They were the perfect collaboration partner to create Quilkin with, given their team’s experience with large scale real time multiplayer games.  

Quilkin is an open-source, non-transparent UDP proxy specifically designed for use with large scale multiplayer dedicated game server deployments, to ensure security, access control, telemetry data, metrics and more.

Quilkin is designed to be used behind game clients as well as in front of dedicated game servers, and offers the following major benefits:

• Obfuscation. Non-transparent proxying of UDP data, making the internal state of your game architecture less visible to bad actors.
• Out of the box metrics. For UDP packet traffic and communication.
• Visibility. A composable set of processing filters that can be applied for routing, access control, rate limiting, and more.
• Flexibility. Ability to to be utilised as a standalone binary, with no client/server changes required or as a Rust library, depending on how deep an integration you wish for your system and/or custom processing Filters you wish to build.
• Compatibility. Can be integrated with existing C/C++ code bases via Rust FFI, if required.
• Onboarding. Multiple integration patterns, allowing you to choose the level of integration that makes sense for your architecture and existing platform.

Until now, these sorts of capabilities are only available to large game studios with resources to build their own proprietary technology. 

We think leveling the playing field for everyone in the games industry is an important and worthy endeavor. That’s why we collaborated with Google Cloud and initiated this project together.

At Embark, we believe open source is the future of the games industry and that open, cross-company collaboration is the way forward, so that all studios, regardless of size, are able to achieve the same level of technical capabilities. —Luna Duclos, Tech Lead, Embark Studios

Google Cloud is excited to announce Quilkin as the latest entry in our portfolio of open-source solutions for gaming.  Quilkin complements our existing OSS solutions including Agones for game servers, Open Match for matchmaking, and Open Saves for persistence.  These are designed to work together as an open and integrated ecosystem for gaming.  We’re proud to include Embark Studios as our latest open source collaborator for gaming along with Ubisoft, Unity, and 2K Games.  Google Cloud will continue to work closely with our partners in industry and the community to offer planet-scale solutions to power the world’s largest games. —Rob Martin, Chief Architect, Google Cloud for Games

Getting started with Quilkin

While Quilkin can support more advanced deployment scenarios like above, the easiest way to get started with Quilkin is to deploy it as a sidecar to your existing dedicated game server. This may initially limit some of the benefits, but it’s an easy path to getting metrics and telemetry data about your UDP communication, with a very low barrier to entry and the ability to expand over time.

While Quilkin is released as both binaries and container images, and is not tied to any specific hosting platform, we’ll use Agones and Google Cloud Game Servers as our game server hosting platform for this example.

First we will create a ConfigMap to store the yaml for a static configuration for Quilkin that will accept connections on port 26001 and route then to the Xonotic (an open source, multiplayer FPS game) dedicated game server on port 26000:

  apiVersion: v1
kind: ConfigMap
metadata:
  name: quilkin-config
data:
  quilkin.yaml: |  # quilkin configuration
    version: v1alpha1
    proxy:
      port: 26001
    static:
      endpoints:
        - address: 127.0.0.1:26000

Second, we’ll take the example container that Agones provides for the Xonotic dedicated game server, and  run Quilkin alongside each dedicated game server as a sidecar, in an Agones Fleet of game servers like so:

  apiVersion: "agones.dev/v1"
kind: Fleet
metadata:
  name: xonotic-sidecar
spec:
  replicas: 2
  template:
    spec:
      container: xonotic
      ports:
        - name: default
          containerPort: 26001
          container: quilkin
      health:
        initialDelaySeconds: 30
        periodSeconds: 60
      template:
        spec:
          containers:
            - name: xonotic
              image: gcr.io/agones-images/xonotic-example:0.8
            - name: quilkin  # quilkin sidecar
              image: us-docker.pkg.dev/quilkin/release/quilkin:0.1.0
              volumeMounts:
                - name: config
                  mountPath: "/etc/quilkin"
              livenessProbe:
                httpGet:
                  path: /live
                  port: 9091
                initialDelaySeconds: 3
                periodSeconds: 2
          volumes:
            - name: config
              configMap:
                name: quilkin-config

Once applied, when we query the cluster for the running GameServers, everything looks the same as it would without Quilkin! Nothing else in our system needs to be aware that the traffic is being intercepted, and we can freely take advantage of the functionality of Quilkin without adjusting either client or server code.

  $ kubectl get gameservers
NAME                          STATE   ADDRESS         PORT   NODE           AGE
xonotic-sidecar-gdpgn-2pfkc   Ready   34.95.106.201   7929   gke-0f7d8adc   25m
xonotic-sidecar-gdpgn-c8bds   Ready   34.95.106.201   7028   gke-0f7d8adc   25m

If this has piqued your interest, make sure to have a look at the walkthrough, where we step through this same scenario and then extend it to compress UDP packets from the game client to server, without having to change either programs.

This just scratches the surface, however: there’s even more to Quilkin, including an xDS compliant admin API, a variety of existing Filters to manipulate and route UDP packets and more.

What’s next for Quilkin

Quilkin is still in its early stages, with this 0.1.0 alpha release, but we’re very happy with the foundation that has been laid.

There are a variety of features in the roadmap, from enhanced metrics and telemetry, new filters and filter types, and more.

If you would like to try out this release, you can grab the binaries or container images from our releases page, step through our quickstarts and review different integration options with your dedicated game servers.

Indonesia is leading the way for digital transformation in Southeast Asia. According to Google’s e-Conomy South East Asia report, the country’s 2030 Gross Merchandise Value – the value of online retailing to consumers –  could be twice the value of the whole of Southeast Asia today.  

This growth means that many companies need more qualified IT graduates and employees with digital skills than they have today. Fast-growing tech companies need more qualified IT graduates, and employees with digital skills. According to the World Bank, Indonesia needs an additional nine million people with digital skills by 2030. The shortage of technical talent reiterates the need to invest in a reliable skills pipeline.

Following years of digital talent developments in Indonesia, Google has become a supporter of Bangkit, an academy designed to produce high-caliber technical talent for Indonesian technology companies and startups. Bangkit has facilitated a multi-stakeholder collaboration between Google, government, industry, and universities across Indonesia. 

Last year, the President of Indonesia and the Ministry of Education and Culture, Research, and Technology, acknowledged Bangkit’s significant impact, with 3,000 students completing nearly 15,000 courses and specialisations. 

Building on last year’s success, Bangkit started its 2022 program in February, offering three learning paths to students:

• Cloud computing with Google Cloud, preparing students for the Google Associate Cloud Engineer certification. Some of the course components are also available online 
• Mobile development with Android, preparing students for the Google Associate Android Developer exam. An online version is available here. 
• Machine learning with Tensorflow, getting students ready to take the Tensorflow Developer certification. Some of the online courses are available here for others.

Bangkit 2022 has enrolled 3,100 university students who will take a five month study course, obtaining university study credit, as well as industry certifications. The program accepts diverse cohorts of people who are passionate about preparing for a tech career in the near future, with support and encouragement for women, people with disabilities, and students from across Indonesia to apply. 

Since its pilot in 2019, Bangkit has been guided by three principles:  

• Industry-led: provides curriculum and instructors from industry experts, including Google, GoTo and Traveloka. Instructors include key figures such as Laurence Moroney (Google, Lead AI Advocate), Google Developer Experts, and other committed professionals. 
• Immersive: combines online learning methods conducted in both individual and group settings.  
• Interdisciplinary: contains knowledge and best practices in tech, soft skills, and English to provide complete career readiness. 

The program runs from February to July 2022, and has a 900-hour curriculum throughout the 18-week learning experience. 

Benefits for students participating in Bangkit include:

• Study credit conversion 
• Job opportunities at our career fair
• Google Cloud, TensorFlow and AAD exam vouchers
• Incubation funds and mentorship support from industry

Towards the end of Bangkit 2022, students will team up for the Capstone Project challenge to propose solutions to some of the nation’s most pressing problems, such as environmentalism, accessibility, and more. The top 15 teams will be selected to receive funding to incubate their capstone projects. These education and career-preparedness offerings are provided at no cost.

Google is partnering with industry, governments, universities, and employers to help meet the skill demands of today.
