Enterprise IT systems
We design and manage enterprise-grade IT infrastructures focused on availability, resilience, and automation. We provide design, integration, and operations for on-premise, cloud, and hybrid environments, focusing on non-functional requirements (high availability, scalability, security, observability) and operational metrics (service level agreements, RTOs, RPOs).
Scope of services offered
- Assessment and architecture: current state analysis, critical service mapping, definition of non-functional requirements, and target architecture design.
- Cloud migration and integration: lift and shift strategies, refactoring, and replatforming; hybrid and multi-cloud architecture design; cloud networking and cost optimization.
- Network infrastructure and connectivity: LAN/WAN design, VLAN segmentation, SD WAN, BGP routing, site-to-site VPN, and secure remote access.
- Virtualization and containerization: VMware/Hyper V cluster design and management; container orchestration with Kubernetes; distributed storage and persistent volume management.
- Storage and data: block/object/file solutions; integration with S3 or S3-compatible storage; replication and tiering strategies for performance and cost.
- Backup and disaster recovery: RTO/RPO definition, incremental backup solutions, geographic replication, and tested recovery plans.
- Security and identity: IAM implementation, SSO, MFA, PKI certificate management, encryption at rest/in transit, system hardening, vulnerability management, and patching.
- Observability and operational management: monitoring, centralized logging, distributed tracing, alerting, and capacity planning.
- Managed services and support: helpdesk, operational runbooks, patch management, customized SLAs.
Technology components and recommended practices
- Infrastructure as Code: Terraform, Ansible for repeatable and versioned provisioning.
- CI/CD and automation: pipelines for build, test, and deployment; integration with security scanning tools.
- Container Platform: Kubernetes with lifecycle management, ingress controller, optional service mesh for microservices.
- Storage and virtualization: enterprise solutions for high availability and snapshotting; integration with S3 object storage.
- Observability: metrics and alerting with Prometheus/Grafana; log aggregation with ELK/Opensearch; distributed tracing.
- Security: next-generation firewalls, IDS/IPS, endpoint protection, NAC, segmentation, centralized policy management.
- Identity and Access: Active Directory/LDAP, OAuth2/OpenID Connect, privileged management, and role-based access control.
Operational methodology
- Requirements-driven approach: We translate business objectives into measurable technical requirements.
- Modular and repeatable design: architectural blueprints, IaC templates, and operational playbooks.
- Testing and validation: resilience testing, failover, recovery drills, and performance testing.
- Change management: change management with rollback plans and deployment canary/blue green when applicable.
- Documentation and skills transfer: runbooks, network diagrams, recovery playbooks, and operational training.
Security, compliance and continuity
- Multi-layered security model: defense-in-depth, encryption, key management, and privilege segregation.
- Compliance and auditing: support for regulatory requirements and audit trails; log retention and access control for evidence.
- Business continuity: DR plans, geographic replication, and periodic testing to ensure agreed-upon RTO/RPO objectives.
