Cloud and infrastructure: Your infrastructure. Ready for what’s next.

We start with how your application works, its workload and how it will be operated.

• Virtual machines and compute: Virtual machines (VMs) and compute services provide the resources needed by systems and applications.
• Containers: Docker and Podman run applications in containers. Kubernetes orchestrates containerized workloads when the project’s complexity justifies it; it does not guarantee high availability on its own.
• Microservices: We organize communication, dependencies and deployments when a microservices architecture suits the project.

These services are not interchangeable. The choice depends on queries, volume, data consistency and the features your application uses.

• Databases: SQLite is embedded in the application; MySQL, MariaDB and PostgreSQL run as database servers. D1 is Cloudflare’s managed service built on SQLite, with its own limits and access methods.
• Caches and key-value storage: Redis and Valkey support caching and other application uses. Compatibility depends on versions, commands and modules. Workers KV is distributed, eventually consistent key-value storage, not a direct replacement for Redis or Valkey or a transactional coordination service.
• Connections: Hyperdrive accelerates access to an existing database through connection pooling, with configurable query caching. It is not a database; engines, drivers and features must be compatible.

We distinguish public-facing services from resources that should be accessible only to authorized systems and people.

• Private networks: Virtual private clouds (VPCs), private subnets, traffic filtering rules and VPNs connect components using the provider’s available capabilities. A VPN can also connect your offices or local storage to the cloud, depending on your needs.
• Service access: DNS, TLS certificates and load balancing direct connections to the right services. Access rights and secrets are managed with the selected tools.
• Web protection: A web application firewall (WAF) can filter certain malicious requests. It complements patching and application security rather than replacing them.

It aims to limit interruptions caused by failures anticipated in its design. Its scope reflects your priorities and available budget.

• Resilience: Redundancy, health checks and failover mechanisms are defined for the relevant components. Dependencies and failure scenarios also need assessment.
• Limits: High availability is not a guarantee of uninterrupted service. An update, incident or failure outside its design can still affect service.
• Backup and recovery: Replication and high availability do not replace backups. Copies, retention, restoration and recovery objectives are defined separately.

We select information that helps explain the environment and guide action, rather than accumulating alerts without context.

• Observability: Monitoring, logs, metrics and alerting provide visibility into service health. Their destinations, access and retention periods are defined.
• Capacity and costs: Resource usage and provider spending help identify limits, overprovisioning and opportunities for optimization.
• Response: Alert recipients, responsibilities and response arrangements are set out in the management scope.

We prepare dependencies, access and checks before changing the environment. Cutover is planned with a rollback path where one is possible.

• Migration: An inventory, testing, data transfers and post-cutover checks give the change a clear structure. Anticipated interruptions are discussed beforehand.
• Infrastructure as code: Versioned configurations and CI/CD processes can make infrastructure changes reproducible, with appropriate checks and access controls.
• Application responsibilities: Nuagerie handles the infrastructure and agreed automation. Business logic, features and application maintenance are covered by a separate engagement, with your team or Nuagiciel.

Yes. You keep your environment and provider accounts; we take on management, clarify access and organize ongoing care. We can also help you choose a platform that fits your applications, budget and data-location requirements.
