What DevOps and Cloud Services Does CelloIP Offer?

CelloIP Technologies provides end-to-end DevOps and cloud infrastructure services including Kubernetes cluster management, CI/CD pipeline setup with GitHub Actions and GitLab CI, Docker containerization, cloud architecture on AWS and GCP, infrastructure-as-code with Terraform, monitoring with Prometheus and Grafana, and cloud migration for VoIP and web platforms.

How Does Kubernetes Help VoIP Infrastructure Scaling?

Kubernetes enables VoIP platforms to auto-scale media servers, SIP proxies, and WebRTC gateways based on call volume. CelloIP deploys FreeSWITCH, Kamailio, and LiveKit on Kubernetes with horizontal pod autoscaling, persistent volume claims for CDR storage, and health-check probes for zero-downtime deployments.

What Cloud Providers Does CelloIP Work With?

CelloIP builds cloud infrastructure on AWS (EC2, EKS, RDS, S3, CloudFront), Google Cloud Platform (GKE, Cloud Run, Cloud SQL), and on-premise Kubernetes clusters using bare-metal servers. We also configure hybrid cloud architectures where on-premise SIP infrastructure connects to cloud-hosted media servers.

How Much Do Cloud and DevOps Services Cost?

Cloud and DevOps engagements start from $5,000 for CI/CD setup and containerization projects, ranging to $100,000+ for full multi-region VoIP infrastructure builds. Ongoing DevOps retainer packages start from $4,000/month.

Our Cloud Engineering Process

Five structured phases from audit to fully operational observability stack.

01

Infrastructure Audit

We assess your current stack — cloud spend, bottlenecks, security posture, deployment frequency, and incident response capability.

02

Architecture Design

We design a cloud-native target architecture with multi-region topology, network segmentation, and service mesh where applicable.

03

IaC Foundations

All infrastructure is codified in Terraform or CDK with remote state, modular design, and policy-as-code from day one.

04

CI/CD Implementation

Build, test, and deploy pipelines wired to your Git workflow. Feature branches, PR previews, and environment promotion gates.

05

Monitoring & Runbooks

Full observability stack deployed, dashboards built per service, alert routing configured, and DR runbooks documented and tested.

Why CelloIP for Cloud Infrastructure

Twelve years of VoIP expertise, applied to the full cloud-native stack.

VoIP-Native Cloud Expertise

We know the unique challenges of running FreeSWITCH and Asterisk on Kubernetes — StatefulSets, RTP port ranges, SIP NAT traversal, and sticky session handling in containerised environments.

GitOps-First Philosophy

Every infrastructure change flows through Git. No click-ops, no tribal knowledge. Pull requests, code reviews, and automated plan diffs for every change, forever.

IaC From Day One

We never provision infrastructure manually. Terraform or CDK from the very first resource — so your infrastructure is auditable, reproducible, and disaster-recoverable from the start.

Full Observability Stack

We deploy the complete Prometheus/Grafana/Loki/Jaeger stack and build custom dashboards for your specific workloads — not generic templates. You always know what is happening inside your system.

Multi-Cloud Without Lock-In

We design workloads to be cloud-portable. Kubernetes as the abstraction layer, Terraform as the IaC foundation, and open-source tooling that runs identically on AWS, GCP, and Azure.

SRE-Grade Reliability

Sub-15-minute RTO via automated failover, circuit breakers, and runbook automation. We define SLOs, measure error budgets, and build reliability into the platform from the architecture stage.

Running VoIP Workloads on Kubernetes

VoIP on Kubernetes is fundamentally different from stateless web services. RTP media streams require predictable latency, not just availability. FreeSWITCH and Asterisk maintain in-memory call state — making StatefulSets, sticky sessions, and graceful shutdown hooks essential, not optional.

We handle RTP port range mapping via hostPort or NodePort, disable SIP ALG on cloud load balancers, tune kernel network buffers (net.core.rmem_max / wmem_max), and implement SIGTERM-aware pre-stop lifecycle hooks to prevent mid-call teardowns during pod evictions. Our blue-green deployment strategy for VoIP services routes new calls exclusively to the new pod version while allowing in-flight calls on the old pod to complete gracefully before decommissioning.

Media servers benefit from CPU affinity and NUMA-aware scheduling. We configure pod QoS as Guaranteed (not Burstable) for FreeSWITCH pods, ensuring the Kubernetes scheduler does not preempt RTP processing threads under memory pressure. These are details most generic DevOps teams miss — and they cause hard-to-diagnose one-way audio bugs in production.

Infrastructure as Code Philosophy

We treat every cloud resource the same way software engineers treat application code: version-controlled, peer-reviewed, and continuously tested. The principle is that if a resource was not created by code, it effectively does not exist — because it cannot be audited, reproduced, or reliably recovered in a disaster scenario.

Our Terraform modules are structured for composability — VPC, EKS cluster, RDS, and IAM roles are separate modules that can be composed per environment without duplication. Remote state is stored in encrypted S3 with DynamoDB locking, and Atlantis provides PR-level plan previews so infrastructure changes go through the same review workflow as application code. OPA Conftest policies enforce naming conventions, tagging requirements, and security baselines before any plan is applied.

Frequently Asked Questions

Common questions about cloud infrastructure engagements.

Can you migrate our existing infrastructure to Kubernetes without downtime?
Yes. We use a phased migration approach: containerise services one at a time, run them in parallel with the legacy environment, shift traffic progressively via weighted load balancing, then decommission old infrastructure only after stability is confirmed. Zero-downtime migrations are standard practice for us.
Do you support all three major cloud providers?
Yes — AWS, GCP, and Azure. We can deploy to a single provider or architect a true multi-cloud topology with workload-specific placement. Our Terraform modules are provider-agnostic where possible, reducing long-term lock-in risk.
How do you handle VoIP workloads specifically on Kubernetes?
VoIP on Kubernetes has specific challenges: StatefulSets for session persistence, hostPort or NodePort for RTP, kernel-level tuning (net.core.rmem_max, SIP ALG disabling), and graceful shutdown hooks to prevent mid-call drops. We have solved all of these in production environments.
What does your monitoring setup look like post-deployment?
You get Prometheus for metrics, Grafana for visualisation, Loki for log aggregation, and Jaeger for distributed tracing. We build per-service dashboards, configure alert thresholds, set up PagerDuty/Opsgenie routing, and document runbooks for every critical alert.
Can you help us achieve SOC2 or ISO 27001 compliance on cloud?
Yes. We map infrastructure controls to SOC2 Type II and ISO 27001 requirements — IAM least-privilege, encryption at rest and in transit, audit logging, secrets management, network segmentation, and vulnerability scanning. We prepare evidence documentation and work alongside your compliance auditor.
What is your typical engagement timeline?
Cloud Starter engagements typically take 4–6 weeks. Production Cloud setups with full observability and CI/CD run 8–12 weeks. Enterprise Cloud projects with multi-cloud, VoIP infrastructure, and compliance work are typically 3–6 months. We deliver in fortnightly sprints with weekly check-ins.
