Cloud Microservices for the Stability of Casino Transactions

Thanks to technology development, entrepreneurs can attract users from different regions. The volume of international transfers is growing. Even a minor delay can provoke discontent among players and negatively affect the reputation of entertainment brands.

To ensure the profitability of gambling platforms, it is essential to provide customers with a fast and secure financial transaction experience. Reliable tools help to easily regulate deposits and withdrawals. This has a positive effect on user experience and the level of trust in the project.

Security and stability of transactions, as well as compliance with anti-fraud policies, are key conditions set forth by regulators.

The Smart Money experts emphasise the importance of utilising cloud microservices when conducting digital transfers. We help casino owners build a reliable business with modern settlement methods.

About the Concept

Microservice architecture is a set of small systems. Each element has a special function. This can be operation processing, client verification, etc.

Such components interact with each other via standardised APIs and can be scaled or updated independently.

Among the well-known cloud platforms that are preferable for deploying such a structure, we can highlight the following:

• ARM;
• Google Cloud Platform;
• Microsoft Azure.

The use of cloud tools makes it possible to perform several actions:

• ensure uninterrupted operation;
• scale the service in accordance with its form;
• quickly update modules without stopping the website’s work;
• rationally solve the problem between data centres.

Each microservice has its environment for storing information. Parameters for configuring system security and product logic are provided. This allows entrepreneurs to effectively adapt solutions to possible changes in regulatory requirements or industry transformations.

Microservice architecture is perfect for complex and dynamic projects with a large number of transfers from other countries.

Cross-Border Transactions in the iGaming Industry

Entertainment portals work in foreign markets, attracting users from different jurisdictions. This leads to the need to carry out international operations, the volumes of which are constantly published.

Here are the main characteristics of data on cross-border transfers in the casino niche:

1. The Statista platform predicts that the total gaming market will cross the $132 billion mark by 2029. This will increase the demand for international transactions.
2. Cryptocurrencies play an important role in this area. Among the most notable resources with digital tokens, Stake, Rollbit, and Roobet stand out in particular. In 2024, they generated more than $80 billion in gross gaming revenue. This is 5 times more than in 2022.
3. About 30% of transfers through e-wallets are international ones. Online casino owners must provide customers from other countries with the ability to quickly and securely replenish their accounts or withdraw prizes.
4. Every year, banking institutions spend more than $120 billion on processing cross-border transactions. This indicates the need to optimise operations to reduce costs.

Let us consider how microservices help entrepreneurs carry out international transfers in the iGaming industry.

Different Jurisdictions and Currencies

To make deposits and withdraw funds, players use local money and various settlement methods:

• bank cards;
• e-wallets;
• mobile payments;
• cryptocurrencies, etc.

Operators need to integrate financial gateways that work reliably in different conditions. Besides, each state has its regulatory standards.

Modern systems make it possible to create separate services for each region:

• one channel works with transfers in euros;
• the second solution accepts money from users who live in Latin America;
• the third service handles cryptocurrency transactions from North America, etc.

Each system is updated, scaled, and adapted to changes in market legislation independently of the others.

The Need for Fast Processing

In the gambling niche, it is very important to ensure the efficiency of transfers — both incoming and outgoing. Even minimal delays will lead to a loss of the users’ trust.

The payment service must be available and stable 24/7, even during high-traffic volumes (such as tournament sessions and seasonal draws).

Optimal indicators can be achieved thanks to the following capabilities of cloud microservices:

• parallel transaction processing;
• automatic scaling in a cloud environment (relevant when there is a sharp increase in the number of players);
• rational distribution of the load on the data centre infrastructure depending on the geographic location of clients.

This ensures the absence of malfunctions and a high level of customer confidence.

Increased Protection

Owners of entertainment sites must comply with international security and regulatory standards:

• KYC — user identification and verification policy;
• PCI DSS — protection rules when processing payment cards;
• AML — measures to prevent money laundering.

It is imperative to take into account local financial and fiscal legislative acts.

Failure to comply with the conditions set by regulatory authorities will result in fines, operational blocking, and even the revocation of a licence.

Cloud tools have made it possible to move away from centralised verification. Each function (for example, monitoring of transactions to prevent money laundering or identity control) is implemented as a separate service.

The use of modern systems for international transfers allows casino owners to perform the following actions:

• adapt to new regulatory requirements without problems and delays;
• neutralise unauthorised logins;
• conduct a detailed audit in each area to compile accurate reports.

Cloud platforms meet key security standards, which has a positive effect on the overall level of portal protection.

Advantages of Cloud Microservices for Casinos

Such solutions bring the following benefits to operators:

Scaling Depending on Traffic

Systems quickly and automatically expand services without the need to stop work. This is very important for iGaming resources during:

• increased peak load (on weekends, holidays, or in the evenings);
• burst of activity in certain regions (on national celebrations);
• marketing campaigns (when many new users come to the website).

Thanks to scaling, transactions are processed without delays, regardless of the traffic volume. At the same time, entrepreneurs do not need to increase the cost of infrastructure maintenance.

Global Availability

Well-known cloud platforms have an extensive network of data centres, which improves the casino’s operation:

• microservices are located closer to clients, which contributes to the speed of transactions;
• separate modules are formed, divided by geography, due to which fault tolerance indicators are significantly improved;
• if a failure occurs in one of the regions, the system from another area “picks up” the tasks, which guarantees continuous work;
• important information from different countries is synchronised online, regardless of time zones.

All these features have a positive effect on the speed of cross-border transaction processing.

Built-In Security and Backup Services

The cloud environment includes the functions necessary to ensure the stability and protection of provided personal details. For safety, the following solutions are used:

• firewalls;
• data encryption;
• role-based access;
• centralised key management.

All operations are monitored in real-time. After the emergence of any anomaly or problem, the system immediately signals violations. The operation to collect and analyse official information is launched.

All data is backed up periodically, which guarantees its quick recovery in case of force majeure.

In What Way Cross-Border Transfers Are Performed

Let's consider a hypothetical scenario of how the cloud architecture of microservices works when processing transactions of this type. Let us assume that online casino servers are located in the countries of the European Union and Canada.

Transfer Initiation

When players need to replenish their accounts, they select the desired option on the website. At this point, the request is sent to the API gateway. Based on the data on the specifics of transactions and the gamblers’ location, the system redirects it to the appropriate payment microservice.

Transaction Processing

The gateway, designed to interact with Canadian users, performs the following actions:

• checking for the availability of funds in the people’s account;
• data validation;
• the sum’s conversion into euros at the current exchange rate.

The system promptly sends the corresponding requests to third-party APIs to collect the necessary information.

Compliance

Another microservice checks for adherence to AML and KYC policies:

• examines personal data;
• analyses previous transfers;
• investigates whether the account has been generating suspicious activity.

Since all processes occur in parallel, the likelihood of a delay in operations is minimised.

Transaction Closing

Once all tests have been performed, another microservice is activated. Its tasks are to:

• save information about the transfer;
• update the gambler's balance in an online casino;
• send a confirmation of the deposit to the user.

Information is exchanged between data centres of the European Union and Canada. This is necessary to comply with local requirements for the processing and storage of personal details. The transfer lasts only a few seconds.

The Main Things about Cloud Microservices in Digital Casinos

For efficiency and ease of interaction with customers from different countries, business owners need to integrate cross-border transaction tools. Cloud microservices can help with this.

Key aspects that entrepreneurs should take into account:

• Systems automatically increase capacity when the load on the platform intensifies. Due to this, the probability of failures becomes minimal.
• Each function is assigned to a separate component of the solution, which makes the transfers more efficient.
• The presence of multiple microservices enables operators to comply with the regulatory requirements of each country and respond promptly to changes in the legislative framework.
