InfotecsTech Builds Custom Kubernetes-Based Traffic Generator for NGFW RnD and Performance Testing
InfotecsTech has detailed the development of its proprietary traffic generator designed to accompany NGFW research, development, and performance validation. The project began with the need to test an active-active NGFW cluster and generate diverse data flows without relying on expensive commercial appliances.
Commercial solutions from IXIA and Xinertel were rejected because of prohibitive pricing at hundreds of gigabits, limited flexibility for testing advanced NGFW features, and geopolitical acquisition barriers. Instead, the team created a scalable, automatable platform that integrates directly into the development workflow.
The architecture runs on Kubernetes with minimal hardware requirements of Debian 12, 8 GB RAM per CPU socket, and 1 Gbit/s network interfaces. A master node provides three core services: Registry for Docker images and metadata, Discovery for managing heterogeneous hardware, and Crux as the REST API operator that orchestrates test execution.
Containerized generators include Cisco TRex for stateless and stateful L3-L7 traffic with DSCP marking, an SIPp-based SIP generator supporting TLS and custom failure scenarios, an FTP generator built on pyftpdlib and aioftp, and a Yandex Tank plus Nginx setup for live TLS sessions using various cipher suites. Additional modules cover APT, DDoS, and web attacks plus Selenium-driven legitimate clients against OWASP Juice Shop.
Real-world test scenarios demonstrated peak VoIP call rates, sustained concurrent connections exceeding 160 million, 400 Gbit/s UDP throughput with 1518-byte packets, 5 million connections per second, and IMIX traffic at 300 Gbit/s with 110 million packets per second. The platform also evaluates behavior under packet loss and integrates Camunda for automated policy application and result collection.

Yandex Black October: How Architectural Flaws and Capacity Mismanagement Turned Data Center Losses Into a 11-Day Fintech Coma
In October 2026 three Yandex data centers in Central Russia were physically destroyed within days, triggering the collapse of Yandex Cloud and multiple core services. Between the first and third site failures engineers had 74 hours to restore quorum and rebalance workloads yet failed to do so because Control Plane components remained tied to the lost zone and spare capacity had been eliminated to cut costs. Core banking and BNPL systems entered Read-Only mode after losing quorum, forcing a complete stop-the-world reconciliation that lasted until 22 October. Backups stored inside the same regional S3 buckets proved unusable, resulting in a seven-day RPO and primary-key collisions after restoration. The incident exposed that Metro-Cluster designs had been incorrectly treated as full Disaster Recovery and that aggressive AP microservice patterns created logical split-brain conditions outside the database layer.
Astra Group Releases Low-Code Astra AI Platform for Building Corporate AI Agents in Closed Environments
Astra Group has launched the Astra AI Platform, a low-code constructor designed for creating corporate AI applications that operate entirely within closed circuits without reliance on foreign clouds. The platform targets small and medium businesses as well as large corporations, enabling rapid deployment of AI secretaries, technical support assistants, and other agents in days rather than months. It forms part of the broader Astra AI ecosystem and includes two main constructors: one for machine learning model training and deployment, and another for LLM-based language assistants, document search, and process automation. Users can assemble scenarios from visual blocks, debug them in real time, or extend functionality with custom Python code when needed. The solution supports RAG-based knowledge bases, integration with external tools such as CRM and ERP systems, and the coordination of multiple agents for distributed task handling. One demonstrated use case involves processing ten pages of engineering drawings and specifications in five minutes to prepare data for downstream systems. The product is already listed in the Russian domestic software registry and available to customers.
Multi-Tenancy Isolation in VictoriaMetrics, VictoriaLogs and Grafana: Building Client Separation in a Shared Stack
Voltir runs a single shared monitoring stack consisting of VictoriaMetrics, VictoriaLogs, Grafana and vmalert for all customers instead of deploying separate instances per tenant. Isolation relies on numeric account IDs enforced at every layer: nginx validates tokens against the platform API before proxying writes, Grafana data sources hard-code tenant accounts, and vmalert rules receive automatic account filters. The team discovered that a single malformed rule or template could break alerting for every tenant because vmalert loads the entire rules directory at once. They also found that Grafana automatically created personal organizations granting Org Admin rights, accumulating hundreds of orphaned organizations and users that consumed disk space and resources. A dedicated cleanup module plus hourly reconciliation now removes rules, organizations, series and users when a tenant is deleted, while isolation tests verify both data and API objects across tenants.
The Real Costs of Using Claude and GPT for Russian Businesses Exposed
Accessing generative AI models like Claude and GPT has become straightforward for Russian companies, yet calculating their true expenses remains complex. Hidden factors such as intermediary commissions, currency conversion rates, taxes, and the often-overlooked costs of model reasoning tokens can double or triple initial estimates. Founder Vitaly Nagay of the Heli service analyzed these financial and organizational risks for Russian firms relying on foreign AI providers. In one example, a support department processing 20,000 monthly queries sees costs rise from $240 to $480 when reasoning tokens are included. Nagay recommends evaluating providers by dividing actual ruble charges by the model's official dollar pricing to reveal hidden markups. Additional concerns involve data control, document compliance, and access history when employees use personal subscriptions. Companies are advised to verify billing details, data storage policies, and issue dedicated API keys with spending limits before procurement.
