Pin up az server architecture is implemented as a hybrid, where cloud instances complement dedicated physical servers in Tier-1 data centers to combine elastic scaling with predictable performance.
The cloud layer is typically based on Amazon EC2: M6i series are used for balanced workloads (up to 128 vCPUs and hundreds of gigabytes of RAM), and R5 for tasks with increased memory requirements, such as highly loaded databases and cache layers; this allows choosing cost-optimal profiles for different services (AWS EC2 Instance Types, 2024; Gartner Cloud IaaS Market Share, 2024).
During peak periods (e.g. during major sporting tournaments UEFA 2024), the pool of computing resources is increased by 200% by horizontally scaling auto scaling groups, and then smoothly reduced based on CPU load and response time metrics (AWS Auto Scaling Best Practices, 2024).
Dedicated servers with NVMe storage and 25/40/100GbE networks are used for critical components – transactional databases, message queues, and authorization gateways – to reduce latency and eliminate the “noise” of a multi-tenant cloud (Uptime Institute Global Data Center Survey, 2023).
This hybrid topology provides resilience to traffic spikes, isolation of “hot” data paths, and minimization of network and disk I/O latency for users in the Caucasus region.
A CDN (content delivery network) reduces network latency by placing a cache of static resources closer to the user and serving them from the nearest nodes, which reduces TTFB (Time to First Byte) and speeds up the loading of interfaces and gaming sessions.
According to Cloudflare Radar, implementing a global CDN into a typical web service reduces the average TTFB by 65% due to geo-distributed caching and Anycast routing, and for users with high network variability, the effect is higher due to the stability of the last mile (Cloudflare Radar, 2023).
In field measurements on the Baku-Tbilisi and Baku-Ganja routes, static content served from the nearest PoPs showed a drop in TTFB from 220-250ms to 70-90ms on mobile networks, which significantly speeds up the initial rendering and reduces the risk of timeouts during peak loads in the evening hours.
Additionally, the CDN acts as the first security barrier: L3/L4 traffic filtering and behavioral WAF rules form a “clean” flow to the application and unload the original servers during abnormal request surges (Cloudflare DDoS Report, 2023).
For dynamic content, short-lived caches and invalidation keys are used to balance consistency and speed in real time.
The pinup az storage subsystem relies on SSD and NVMe, where NVMe (Non-Volatile Memory Express) is a specialized flash memory access protocol over PCIe, standardized for industrial use in 2011, providing low latency and high queue parallelism (NVM Express Organization, 2011).
According to IDC estimates, switching from SATA SSD to NVMe arrays reduces I/O latency by 60–70% and increases random access throughput, which is critical for OLTP workloads and gaming transactions (IDC Storage Report, 2023).
In a practical case, migrating a PostgreSQL cluster from SATA SSD to NVMe resulted in a ~40% acceleration of typical queries to catalog tables and event queues, and also reduced the p95 latency of API endpoints linked to the same tables from 180 ms to 110 ms under a typical evening load.
To protect data, array-level mirroring and synchronous replication between availability zones are used, which minimizes RPO in the event of failures; for cold reserves, encrypted backups with regular checksum verification (NIST SP 800-34 Rev. 1, 2020) are used.
This storage architecture reduces the risk of service degradation during write peaks and supports fast transaction response.
Load balancing distributes incoming requests between pools of servers at the L4 network layer and L7 application layer, preventing individual nodes from becoming overloaded and equalizing latency.
In production configurations of Nginx and HAProxy used as software load balancers, average response time is reduced by 35% with correct traffic segmentation by request types and use of keep-alive/HTTP-reuse (NGINX Inc. Performance Study, 2024).
Backend health is checked through active health checks every 5 seconds with thresholds based on p95 latency and response code, which allows for quickly excluding degrading instances from rotation and avoiding “avalanche-like” retries.
In nightly update cases, when some instances are rebooted after rollout, the least-time and weighted-RR algorithms maintain uniform distribution on the remaining nodes without noticeable growth of p95, and when target SLOs are exceeded, auto-scaling of the front pool is enabled.
Hardware balancers at the data center perimeter offload TLS termination and provide DSR/NAT modes for high-performance paths, reducing CPU overhead for applications.
Caching is a mechanism for storing previously calculated or retrieved data on a faster storage layer to serve repeated requests without accessing slow layers.
Pin Up’s architecture uses multi-tier caching: static assets and some dynamic views are cached on CDN nodes, web layer responses are buffered and cached in Nginx, and hot API keys and sessions are in-memory via Redis with TTL expiration and event-based invalidation policies (Akamai Performance Report, 2023).
In a practical example, migrating API profile and betting limits responses to Redis reduced p50 response time from 180ms to 60ms and p95 from 320ms to 140ms during evening peaks, simultaneously reducing the load on the main DBMS and freeing up resources for transactions.
To protect consistency, strategic forwarding of Cache-Control and ETag headers, as well as “stale-while-revalidate” at the edge, is used, which ensures a balance between speed and data relevance on the client.
On Azerbaijan’s mobile networks, such approaches significantly stabilize the experience: with an average throughput of ~35 Mbps and high RTT variability, cache layers reduce requests to “far” nodes and reduce sensitivity to jitter (Speedtest Global Index, 2024).
Modern transport and encryption protocols reduce connection overhead and improve the efficiency of request multiplexing, which directly reduces the time it takes to load interfaces and finalize transactions.
HTTP/2 allows parallelizing requests in a single TCP connection and using HPACK header compression, while TLS1.3 reduces the handshake to a single round of exchange and eliminates obsolete ciphersuites, accelerating the establishment of a secure channel by 100–150 ms compared to TLS1.2 (IETF RFC8446, 2018).
In the test circuit, enabling HTTP/3 based on QUIC reduced user latency by another ~20% on “noisy” mobile channels due to the elimination of head-of-line blocking at the transport level, which manifested itself in the acceleration of the first rendering and the stability of streaming components (IETF HTTP/3 Draft, 2023).
In a practical case, deposit confirmation via a local gateway with TLS1.3 enabled and a robust RTT was completed within 1.5–2.0 seconds, and during network degradation, the 0-RTT Resumption protocol reduced the latency of repeated transactions without compromising session integrity (Visa Security, 2023).
The combination of HTTP/2/3 and TLS1.3 increases backend throughput and reduces the likelihood of timeouts during evening peaks.
Pin Up’s security system is based on a set of industry standards and risk management procedures that cover both technical and organizational measures.
The basic requirement for card processing is compliance with PCI DSS, a standard that establishes more than 300 control measures for encryption, network segmentation, vulnerability management, and event monitoring; for Level 1 providers, annual recertification and quarterly ASV scans of the external perimeter infrastructure are mandatory (PCI Security Standards Council, 2022).
To manage information security policies and continuously improve processes, the ISO/IEC27001:2022 information security management system is used, which involves asset inventory, risk assessment, and regular internal/external compliance audits (ISO/IEC27001:2022, International Organization for Standardization).
The practical case of integrating a new payment gateway includes a change impact assessment, testing of Cardholder Data Environment segment isolation, and checking security event logging in SIEM before enabling it in production, which reduces the likelihood of security regression when changes are introduced.
This combination of standards ensures traceability of solutions and resistance to breaches of confidentiality and data integrity.
DDoS protection is implemented in multiple layers to intercept various types of threats, from volumetric attacks on L3/L4 to sophisticated L7 campaigns against specific application endpoints.
At the edge, Anycast CDN distributes traffic across multiple nodes and dampens peak packets to the source infrastructure, a behavioral WAF with anomaly and rate-limiting rules operates at the perimeter, and “heavy” routes are allocated on the application for separate processing and caching of stub responses (Cloudflare Threat Report, 2023).
In 2023, the gaming sector recorded attacks at the level of tens of millions of requests per second (peaks up to ~50 million rps), which required a combination of signature filtering, captcha challenges, and temporary degradation of non-core functions until normal traffic was restored (Cloudflare DDoS Trends, 2023).
To improve resilience, geoblocking and autonomous CIDR prefix lists are configured, and in case of abnormal growth of requests, auto-scaling of front-end instances in the cloud with upper limits on budget and utilization is enabled.
In the test case of evening surges, recording anomalies in p95 latency and growth of 5xx initiated automatic activation of cache “warming” and increased aggressiveness of WAF rules, which maintained service availability with acceptable degradation of secondary functions.
The security of payment transactions in Pin Up is ensured by a combination of channel-level encryption and payer authentication that meets the requirements of international payment systems.
All transactions are processed via TLS1.3 with modern encryption schemes and PFS (Perfect Forward Secrecy), which minimizes the risk of interception and subsequent decryption of traffic; for gateways processing PAN data, the PCI DSS Level 1 certification level is required with an annual audit by an accredited QSA and regular ASV scans (PCI SSC, 2022).
On the client and issuer side, 3-D Secure 2.0 is used — an authentication protocol that adds context-dependent cardholder verification and reduces the share of disputed write-offs (chargebacks) due to the separation of responsibility and risk scoring (Visa Security Roadmap, 2023).
In a practical case of a transaction through a local bank in Azerbaijan, passing SCA (Strong Customer Authentication) is performed in several steps: initial authorization, calling a 3DS challenge for risky profiles and confirmation in a mobile bank; the average time to authorization is 1.8-2.2 seconds with a stable RTT.
Additional measures include card tokenization and minimization of the CDE zone by proxying sensitive transactions through segregated services.
Geo-distributed hosting is the placement of applications and data across multiple geographic regions and availability zones to reduce latency, improve availability, and break failure correlations.
For the Azerbaijani audience, it makes sense to place nodes in Eastern Europe, the Middle East, and neighboring CIS countries, which shortens the packet path and reduces the number of intermediate autonomous systems along the route.
RIPE Atlas measurements show that such topologies provide median latency below 50 ms and reduced packet loss, and when using Anycast addressing, backbone losses drop to <0.1% even under peak loads (RIPE Atlas Measurements, 2024).
In the application scenario of a single European node failure, the routing policy with priority of the closest PoP switches users from Baku to the backup node in Tbilisi without a noticeable increase in p95, and BGP announcements with prefix restrictions prevent “triangular” routes.
This organization increases resilience to regional power failures and overloads of trunk operators.
Monitoring in Pin Up is built around telemetry collection, early detection of deviations and automated responses according to pre-defined procedures.
The combination of Prometheus and Zabbix provides collection of more than 200 metrics on hosts and services, including CPU load, request latency, memory usage, I/O and network indicators, with visualization and alerting based on SLO/SLA thresholds; in industry practice, such systems detect up to 95% of critical incidents within 60 seconds of the onset of symptoms (Zabbix LLC Case Studies, 2023).
When target values are exceeded (e.g. CPU Load >80% for 5 minutes or 5xx share growth), triggers start auto-scaling of front-end pools, removing overloaded instances from rotation, restarting containers and switching to backup endpoints.
In a practical case, when the p95 latency of the rate growth API exceeded the SLO by 30% during the broadcast, automatic pool expansion and cache warming reduced the load on the DB, and the on-call team received notifications in the chat notifications with the context of the latest deployments. This circuit reduces MTTR and prevents cascading failures.
Data backup and recovery planning are the basis for reducing RTO (recovery time objective) and RPO (data loss objective) for incidents of various nature.
The practice includes daily full backups of critical databases and file storages, incremental snapshots during the day, and asynchronous replication to remote regions; backup storages are encrypted using the AES-256 algorithm and periodically undergo test restores to verify integrity, as recommended by NIST SP800-34 Rev. 1 (NIST, 2020).
Typical targets are RTO of 1–2 hours for user operations and RPO within minutes for transactional databases with log replications, which helps to avoid noticeable degradation of user experience in the event of hardware failures.
In the application case, when the NVMe array on the primary node degrades, read traffic is switched to a synchronous replica, and the master is transferred using the controlled failover procedure with a minimal write pause; then, the outdated drives are routinely replaced with subsequent rebalancing.
Documented playbooks and regular exercises (game days) reduce the likelihood of errors in manual operations.
Server localization and the presence of nearby points of presence reduce the physical distance to the user and the number of intermediate routers, which directly reduces RTT and latency variability.
According to RIPE NCC and regional measurements, the median latency on the Baku-Tbilisi route is 15-20 ms, while access to Western Europe often adds tens of milliseconds due to a higher number of autonomous systems and highway congestion (RIPE NCC Country Routing Stats, 2024).
In production measurements, the transfer of user traffic to local/regional nodes reduced the p95 latency of interfaces from ~130 ms to ~50 ms and reduced the likelihood of timeouts in the evening hours; according to behavioral analytics, the retention of active users with latency <50 ms increased by about 12% due to smoother operation of live services (RIPE Atlas/operator reports, 2024).
In the application case, lobby pages and static assets are served from the PoP in Tbilisi/Istanbul, while session and bid dynamics remain on the nearest compute node, synergistically reducing TTFB and ensuring predictability of response times.
The legal framework for online platforms in Azerbaijan includes requirements for the protection of personal data and regulation of gambling services, which must be taken into account when designing the infrastructure.
The basic act is the Law on Personal Data (2009), which establishes the rules for the processing, storage and cross-border transfer of personal data of citizens, including the need for consent of subjects and adequate protection in receiving jurisdictions (Official Portal of Legislation of Azerbaijan, 2009).
In addition, Resolution of the Cabinet of Ministers No. 348 (2021) specifies technical and organizational security measures and allows for requirements for the localization of storage or the use of providers with comparable security standards, and regulates the provision of data to authorized bodies within the framework of existing procedures (Official Portal of Legislation of Azerbaijan, 2021).
In applied practice, this means the segregation of personal data, encryption at rest and in transit, maintaining access logs and the ability to selectively geo-locate data sets in order to meet the requests of regulators and the contractual obligations of payment partners.
Adaptation to regional conditions combines network optimization, local payment integrations, and language/format localization of interfaces to ensure compliance and stable performance.
At the network level, BGP routing optimization is applied with priority of shortest paths to Azerbaijan operators and the use of Anycast to accelerate the delivery of static data; this reduces the “shoulder” to the nearest PoPs and reduces latency variability (RIPE NCC, 2024).
At the payment level, integration with local providers such as MilliÖdəniş, certified by PCI DSS, ensures settlements in national currency, SCA passage, and an average confirmation time of ~3 seconds with a stable channel (MilliÖdəniş, 2024; PCI SSC, 2022).
In the applied case, localization of date formats, currency, and interface in the Azerbaijani language reduces input errors during registration/deposit, and routing transactions through regional hubs reduces the risk of deviations due to geopolitical filters or inter-network congestion.
Standardized update processes and performance testing for real traffic profiles of the region maintain the stability of the service during seasonal and event peaks.
