The Zombie Apocalypse and Other Cloud Infrastructure Concerns
By Liz Durst

Last month, I returned from an overseas trip to a friend’s wedding to find the zombie apocalypse happening in my neighborhood near downtown San Jose. People of all ages and demographics united together in what looked like strange cult gatherings in public parks, stumbling around the streets of the South Bay with eyes glued to their phones and occasionally yelling something strange like, "OMG I hatched a Nidoking!" Cars would come to abrupt halts in front of me at unexplained times—I half expected a scene from the movie Zombieland to unfold where Woody Harrelson would leap out from an SUV ready to give me the nickname Minnesota and help navigate safely back to my parents’ farm.

Pokémon Go was released in the US on July 6, 2016. Unless you've been living off the grid in a yurt (in which case you won't be reading this blog post), you've probably observed that this was much more than a game release and more like the dawn of a new way of life for some people. While there have been well-publicized challenges as the game has scaled to reach millions, it's an amazing use of cloud that's enabled multiplayer game scalability to connect an unprecedented number of users in only a few weeks.

From a technology standpoint, it's interesting to think about how games and other popular mobile applications can launch seemingly overnight at scale with millions of users. While in the past many gaming companies may have run out of their own data centers or traditional hosting centers, the most common pattern emerging from the industry makes use of a few key Cloud building blocks for gaming servers: load balancers, firewalls and network routing; VMs or containers for the game logic; a scalable document style database; and sometimes SQL databases and a caching tier. Looking at just the last two years, many of these companies have shifted from proprietary architectures to the same patterns and have started speaking at developer and ecosystem events such as the OpenStack and Docker conferences. The appeal of Cloud, and technologies like OpenStack and Docker for the gaming industry, is that they can rely on the scalability of the infrastructure in many layers of the game server architecture for not only scale, but also use a combination of the programmable network/routing layer and load balancers to implement rapid deployment of the game logic layer.

The one spot where I've seen a lot of concern/sensitivity to relying 100% on public Cloud providers in the gaming industry is in protecting their in-game economy servers or their login, authentication and authorization systems, in addition to securing their dev/test environments, and protecting those servers with an extra layer of security. Such game studios have been interesting partners for the IBM / Blue Box team, since they still need the flexibility to scale up their game, but they don't want to have the specialized skills of managing a traditional data center for a couple pieces of their game platform. Cost is also obviously a big sensitivity-even with auto-scaling, public solutions may cost significantly more to meet I/O database performance demands significantly above a well-architected hybrid cloud solution.

Whether or not Pokémon Go is here to stay or is just a fad like collecting Beanie Babies, it's clear that game development is leading the way to vet out next generation Cloud architecture and performance demands (something that all industries should be paying attention to for these use cases). As someone who's a big believer in communities and a gamer, it's awesome to see this type of collaborative approach to pushing the boundaries of open source projects by pairing the intensely technical game development community with technical advocates focused on server side infrastructure such as the IBM Cloud team!

With more than 30 Kubernetes solutions in the marketplace, it's tempting to think Kubernetes and the vendor ecosystem has solved the problem of operationalizing containers at scale or of automatically managing the elasticity of the underlying infrastructure that these solutions need to be truly scalable. Far from it. There are at least six major pain points that companies experience when they try to deploy and run Kubernetes in their complex environments. In this presentation, the speaker will detail these pain points and explain how cloud can address them.
The deluge of IoT sensor data collected from connected devices and the powerful AI required to make that data actionable are giving rise to a hybrid ecosystem in which cloud, on-prem and edge processes become interweaved. Attendees will learn how emerging composable infrastructure solutions deliver the adaptive architecture needed to manage this new data reality. Machine learning algorithms can better anticipate data storms and automate resources to support surges, including fully scalable GPU-centric compute for the most data-intensive applications. Hyperconverged systems already in place can be revitalized with vendor-agnostic, PCIe-deployed, disaggregated approach to composable, maximizing the value of previous investments.
When building large, cloud-based applications that operate at a high scale, it's important to maintain a high availability and resilience to failures. In order to do that, you must be tolerant of failures, even in light of failures in other areas of your application. "Fly two mistakes high" is an old adage in the radio control airplane hobby. It means, fly high enough so that if you make a mistake, you can continue flying with room to still make mistakes. In his session at 18th Cloud Expo, Lee Atchison, Principal Cloud Architect and Advocate at New Relic, discussed how this same philosophy can be applied to highly scaled applications, and can dramatically increase your resilience to failure.
Machine learning has taken residence at our cities' cores and now we can finally have "smart cities." Cities are a collection of buildings made to provide the structure and safety necessary for people to function, create and survive. Buildings are a pool of ever-changing performance data from large automated systems such as heating and cooling to the people that live and work within them. Through machine learning, buildings can optimize performance, reduce costs, and improve occupant comfort by sharing information within the building and with outside city infrastructure via real time shared cloud capabilities.
