Online casinos are more popular than ever, and by this point, everyone with access to the Internet has probably come across these platforms.
Those who have used them know that speed is essential in getting a high-quality gaming experience, as latency is the killer of gambling satisfaction.
Even half a second delay can cause issues, and most software games today come with a warning that malfunctions void game outcomes. Hence, getting seamless gaming is of paramount importance for everyone.
Operators boasting high-end server infrastructure that facilitates not only games being enjoyed appropriately, but also provides high transaction processing, is the hallmark of all top and proven secure online casinos.
No one wants to use sites they know may have trouble handling traffic spikes, which can affect the level of service they get.
Game availability, fairness, regulatory compliance, financial safety, and more get influenced by server quality, and having stable servers goes a long way in building customer trust, and not having them can have severe reputational consequences.
Below, we go into the foundation of this infrastructure and how it influences overall gaming fun.
The Core Architecture
For the most part, if not universally, online casinos have distributed architecture. This is a reference to the fact that their services are spread across multiple data centers. This is not something that is done entirely for scaling purposes. No.
It is also done out of legal compliance, as some regulators and laws demand this for safety. Sometimes, demands state that no servers can be located outside a country’s borders, as it is often forbidden for data processing to happen in another jurisdiction.
This is typical for strictly regulated markets, but is something that lax ones allow. For example, most Curacao-licensed casino sites have their servers in this Caribbean nation, but their processing agents are in countries with loose financial laws, such as Cyprus.
In general, casino architecture features multiple layers, with edge servers and content delivery networks at the front reserved for static assets, meaning graphics, animations, CSS, and the like. These nodes cache aggressively, allowing presentation-based elements to load quickly.
Behind the CDN, application servers handle the business logic. Hence, these handle bet processing, game engines, coordinate with payment gateways, and so on.
Below them are databases, which combine in-memory caches and databases for transaction and account records. Note that load balancing occurs at every junction.
Non-Casino Game Servers
Now, here is a mistake that most new to this sphere make. Novices typically believe that their chosen casino sites host the games they play. Usually, this is not the case. Online casinos, as a rule of thumb, are only gateways to products hosted at their partnered providers.
They operate the websites customers use to reach the games, handle their accounts there, offer them bonuses, payment functionality, responsible gambling tools, etc., but the offered games themselves are housed on provider servers.
Top game studios like Play’n GO, NetEnt, and Pragmatic Play feature their gaming creations on their own infrastructure, and they communicate the activity of their games to casinos presenting them through APIs.
This ensures that individual platforms cannot manipulate round outcomes and allows providers to easily deploy bug fixes across the sector.
Though, it has to be highlighted that some big-name operators host their games, and this is traditionally also the case with in-house gaming options. But live casino tables are entirely offered by third-party providers, not individual casino websites.
The Payment Processing Funnel
This works similarly to the game network we explained above. Casinos are responsible for accepting deposits and issuing withdrawals, along with detecting fraud that may have occurred on their platform, running KYC checks, and managing player balances.
Yet, the actual movement of funds happens through payment processor servers. Again, gambling operators are only windows into the infrastructures of these transaction gateways. Think of them as the gaming front end, while processors are the back end.
When someone enters payment details on a casino platform, that site relays that information to the processor, which then contacts the required network and checks to see if the transfer has been approved or declined.
If it has been authorized, the transaction goes through. The money arrives in the casino’s balance, which then credits it to the player’s account.
Now, casinos do not have connections with all banks worldwide; they use trusted third-party processors, which ensure PCI DSS compliance, handle currency conversion, and more.
