Self-hosted Infrastructure

Self-hosted infrastructure puts you in complete control — of data, costs, and operational decisions. Alchemilla Ventures designs, deploys, and manages self-hosted infrastructure for organisations that value independence from public cloud platforms.

Why Self-Host?

Not every organisation should rush to the cloud. Self-hosted infrastructure offers:

• Complete data control — no foreign jurisdiction exposure, full compliance with data localisation
• Predictable costs — no surprise cloud bills; capital expenditure with known depreciation
• Performance — local network latency, no noisy neighbours, guaranteed resources
• Customisation — choose every component, from hypervisor to monitoring tool
• Independence — no vendor lock-in, no dependency on cloud provider roadmaps

Our Self-Hosted Infrastructure Services

• Infrastructure Architecture & Sizing: We design self-hosted infrastructure scaled to your workloads — from a single hyper-converged node for a small business to multi-rack, multi-site deployments for enterprises. Our sizing methodology uses workload profiling, growth projections, and performance requirements to right-size your investment.

• Hardware Procurement & Deployment: Full lifecycle — vendor selection, configuration, procurement, rack-and-stack, cabling, and commissioning. We work with Dell, HPE, Lenovo, and Supermicro for servers; Cisco, Aruba, and Juniper for networking; Pure Storage, NetApp, and Dell for storage. For clients, we handle logistics, customs (for imported equipment), and on-site installation.

• Private Cloud Implementation: Build your own cloud with OpenStack, Apache CloudStack, or VMware Cloud Foundation. We implement self-service portals, automated provisioning, chargeback/showback, and multi-tenancy — bringing cloud-like experience to your data centre. For government and PSU clients, this enables cloud benefits while meeting MeitY empanelment requirements.

• Virtualisation Platforms: Deploy and manage VMware vSphere (the most widely adopted platform in enterprises), Proxmox VE (open-source alternative gaining popularity ), Microsoft Hyper-V, or KVM/oVirt. We configure high-availability clusters, distributed storage (vSAN, Ceph), and disaster recovery with Zerto or Veeam replication to secondary sites.

• Self-Hosted Kubernetes: Deploy Kubernetes on your own hardware — Rancher RKE2, OpenShift, or vanilla Kubeadm. We configure persistent storage (Longhorn, Rook/Ceph), ingress (NGINX, Traefik), service mesh (Istio, Cilium), and GitOps (ArgoCD, Flux). For enterprises wanting cloud-native agility without cloud dependency, self-hosted K8s is the sweet spot.

• Self-Hosted SaaS Alternatives: Deploy self-hosted alternatives to popular SaaS products — Nextcloud (vs. Google Drive/Dropbox), GitLab (vs. GitHub), Mattermost (vs. Slack), Jitsi (vs. Zoom), Matomo (vs. Google Analytics), and n8n (vs. Zapier). For organisations concerned about data sovereignty, these open-source alternatives provide enterprise-grade functionality without sending data to foreign servers.

• Backup & Disaster Recovery: Comprehensive data protection for self-hosted infrastructure — Veeam Backup & Replication, Proxmox Backup Server, or Borg/Restic for file-level backups. We implement 3-2-1 backup strategies with on-premise, off-site (two geographic locations), and tape/cloud archival tiers. DR drills are conducted quarterly to validate RPO/RTO commitments.

• Monitoring & Management: Full-stack monitoring with Prometheus, Grafana, Loki, and Alertmanager. We set up centralised logging, infrastructure dashboards, and alert routing for our NOC or your internal IT team.

Self-Hosted vs. Cloud: Decision Framework

Factor	Self-Hosted Advantage	Cloud Advantage
Data Sovereignty	Absolute control, no foreign jurisdiction	Requires careful region selection and DPA review
Cost (steady workloads)	3-5 year TCO typically lower	Pay-per-use may cost more for steady loads
Cost (variable workloads)	Must size for peak	Elastic scaling, pay only for what you use
Time to deploy	Weeks for procurement and setup	Minutes
Geographic reach	Limited to your data centre locations	Global footprint with few clicks
Operational overhead	Your team (or us) manages hardware	Cloud provider manages physical infra
Vendor lock-in	Low — you own the hardware and software	Varies; managed services create dependency

Why Enterprises Choose Self-Hosted

• BFSI Sector: financial services companies often self-host core banking and trading systems for latency, compliance, and control reasons.
• Manufacturing: factories self-host MES (Manufacturing Execution Systems) and SCADA — these systems need sub-millisecond response and cannot tolerate internet dependency.
• Healthcare: Hospitals self-host PACS (medical imaging) and EMR (electronic medical records) for data privacy and performance — a chest CT scan is 500MB+ and too large for cloud transfer.
• SaaS Providers: SaaS companies often self-host development/staging environments and use cloud only for production — balancing cost and control.
