The Cloud9solution Platform Architecture
Nine explained layers of our infrastructure stack. Use the toggle on any layer to switch between plain-language summaries and technical engineering specifications.
Compute & Hypervisor Layer
We run your applications on enterprise physical servers divided into secure virtual slices. Each server has guaranteed memory and processor capacity so other tenants never slow down your site.
KVM hypervisor clustering with virtio interfaces, NUMA-aware core scheduling, and direct host memory mapping. Hardware scheduling ensures minimal CPU steal time under peak concurrency.
Storage Fabric
Your files and database tables live on ultra-fast solid-state drives. Every piece of data is duplicated across multiple disks so a drive failure causes zero data loss.
Striped NVMe PCIe Gen4 arrays in RAID 10 alongside Ceph distributed block storage clusters communicating across dual 25G interfaces with 3x synchronous data replication.
Transit & Private VPC Subnets
We connect your servers to low-latency Indian internet networks and keep backend databases in private internal networks hidden from the public internet.
Multi-homed BGP routing with direct peering at the National Internet Exchange of India (NIXI). Software-defined VXLAN overlay fabrics provide isolated RFC1918 private subnets.
Perimeter Defense & OS Hardening
We guard the front door against automated attack bots and lock down server ports so only authorized team members can access administrative consoles.
Stateful nftables packet filtering, automated upstream volumetric flood throttling, CIS-benchmark Linux kernel parameter hardening, and mandatory Ed25519 SSH key authentication.
Automated Snapshot Protection
Every night, automated snapshots capture your entire system and database, sending encrypted copies to a separate physical building for safe keeping.
Point-in-time QEMU/KVM snapshot integration coordinated with fsfreeze filesystem quiescence, compressed, encrypted with AES-256-GCM, and streamed to isolated off-site storage pools.
Continuous Telemetry & Proactive Alerts
Automated sensors check your server and website every minute. If CPU usage spikes or a service stops responding, an engineer is alerted immediately.
Prometheus-compatible node collectors transmitting system metrics over mTLS, paired with distributed external synthetic HTTP probes monitoring SSL validity and response latencies.
Horizontal & Vertical Scaling
As your user base grows, you can expand server CPU and RAM without rebuilding your system, or add more parallel servers behind a traffic distributor.
Hot-plug virtual memory expansion, live dynamic storage volume resizes, and automated configuration management templates for deploying identical worker nodes behind HAProxy.
High Availability (HA) Clustering
We pair servers in redundant teams. If one physical node experiences a hardware fault, traffic automatically reroutes to the surviving node in seconds.
Active-passive and active-active clustering utilizing Corosync/Pacemaker virtual IP failovers or Patroni etcd consensus for PostgreSQL, executing primary cutover in under 3 seconds.
Disaster Recovery Standby
A complete standby replica of your environment maintained in a secondary facility, ready to take over live traffic if a catastrophic facility event occurs.
Asynchronous cross-datacenter block replication and database transaction log shipping paired with automated DNS health-check failover to standby pilot-light compute.
