Redundant and multi‑write databases

Multi‑primary topologies with logical replication/write certification, quorum and fencing. Target: RPO ≈ 0 and RTO < 60s in planned or unplanned failures.

PostgreSQL multi‑primary

Bidirectional logical replication with Spock/BDR/pglogical for multi‑site and geo‑distributed topologies.

  • • Replicación lógica (decoding: pgoutput/wal2json), slots y gestión de colas.
  • • Resolución de conflictos: last‑update‑wins, columnas monotónicas, reconciliación basada en versión/TS.
  • • DDL replicate y filtrado por esquema/tablas con mantenimiento en caliente.
  • • Particionado nativo y shard keys para escalado horizontal.
  • • HA local con Patroni/etcd + VIP (keepalived) y STONITH para evitar split‑brain.
  • • Backups PITR con WAL‑G, basebackups incrementales y políticas de retención S3/OSS.
  • • Observabilidad: pg_stat_* , pg_stat_statements, pg_wal_inspect, exporters Prometheus.

MySQL multi‑write

Percona XtraDB Cluster (Galera) or MySQL InnoDB Cluster (Group Replication) in multi‑primary mode.

  • • Certificación de writes (WSREP) y control de flujo; quorum y write‑set replication.
  • • SST/IST, wsrep_provider_options ajustado a latencia intra‑DC (<2ms) y tamaño de transacción.
  • • Capa de acceso: ProxySQL/MySQL Router con split RW, pinning de sesión y read scalability.
  • • Backups consistentes con Percona XtraBackup; DR asíncrono con GTID/binlog a sitio remoto.
  • • Failover orquestado y fencing para prevenir divergencias.
  • • Métricas: wsrep*, performance_schema, exporters Prometheus y alertas SLO.

Access and consistency architecture

  • • Capa L4/L7: HAProxy/Envoy con health‑checks transaccionales, tiempo de drenaje y retries idempotentes.
  • • Políticas de consistencia: fuerte vs. eventual; read‑your‑writes y causal reads por etiqueta.
  • • Esquemas multi‑región: sincrónicos intra‑AZ, semi‑sync/async inter‑región con tolerancia a partición.
  • • Auditoría y cifrado: TDE/at‑rest, TLS mTLS, rotación de claves y row‑level security (PostgreSQL).

Infrastructure and High Availability

Mission-critical architectures with advanced clustering and enterprise virtualization.

HA Clusters

HA architecture and active-active / active-passive load balancing with Pacemaker, Corosync and DRBD. Automatic failover in seconds.

  • • Clustering Linux empresarial
  • • Replicación síncrona DRBD
  • • Failover automático
  • • Disaster recovery (DRS)

Advanced Virtualization

Proxmox VE, KVM and VMware ESXi with distributed storage Ceph, GlusterFS and ZFS for maximum resilience.

  • • Proxmox VE clusters
  • • KVM con SR-IOV
  • • VMware vSphere
  • • Snapshots incrementales

Hybrid Cloud and Containers

Container orchestration and multi-cloud deployments with advanced security.

Kubernetes & Docker

Orchestration with Docker Swarm and Kubernetes. Declarative deployments with Helm and Kustomize.

Multi-tenant Security

Namespaces, RBAC, network policies and service mesh (Istio, Linkerd) for secure environments.

Multi-cloud

AWS, Azure, GCP and OpenStack integration with Terraform for infrastructure as code.

Enterprise Networks and SD-WAN

Advanced Protocols

MPLS, BGP, OSPF with VLAN segmentation and L2/L3 tunneling. QoS and traffic policies.

Corporate VPN

High-performance IPsec, WireGuard and OpenVPN with SD-WAN (Fortinet, Cisco, Mikrotik, pfSense).

Monitoring

NetFlow, SNMPv3 and Zabbix for proactive performance and availability monitoring.

Edge Computing

Distributed deployments with service mesh for minimal latency and local processing.

Automation and Operational AI

Infrastructure as code, CI/CD pipelines and predictive observability with AI.

IaC & DevOps

Ansible, Terraform and SaltStack for infrastructure as code. CI/CD with GitLab, Jenkins and ArgoCD.

Observability

Prometheus, Grafana and Loki for proactive monitoring. Predictive alerts and custom metrics.

Operational AI

Anomaly detection, resource optimization and dynamic autoscaling. Integrated ChatOps and AIOps.

IP Telephony and Unified Communications

Enterprise VoIP platforms with high availability and real-time monitoring.

VoIP Platforms

Asterisk, FreePBX, 3CX with SIP trunk, WebRTC and SRTP integrations for secure communications.
