Shared CPU instances draw from a pool of cores that is fairly scheduled between tenants — excellent value for websites, staging and bursty workloads. Dedicated vCPU (Standard, CPU-Optimised, Memory-Optimised and High-IOPS) reserves each vCPU for you alone, so performance stays consistent under sustained load. Use shared for light or spiky work, dedicated for anything in production that customers or staff depend on.

Start from the bottleneck. Mostly idle or bursty: Shared. General production app: Standard. CPU pinned at 100% for long periods: CPU-Optimised. Database or cache that wants more RAM: Memory-Optimised. Disk queue always busy: High-IOPS. If you're unsure, tell us what you run and we'll size it free.

Windows Server 2019, 2022 and 2025, plus Ubuntu, Debian, AlmaLinux, Rocky Linux, CentOS Stream and FreeBSD. Red Hat Enterprise Linux is available on a bring-your-own-licence basis, and you can upload a custom ISO.

Windows Server licensing is available as a monthly add-on priced per two vCPUs, so you never buy a perpetual licence up front. Linux distributions carry no licence charge.

Every plan runs on enterprise NVMe SSD — including the entry Shared plan. High-IOPS instances add large local NVMe for write-heavy workloads, and you can attach extra block storage volumes to any server.

Yes. You can add vCPU, memory or storage from the console without rebuilding the server; a CPU or RAM change needs a brief reboot. You can also move between instance families as the workload changes.

Both. Pay hourly to test or for short-lived environments, or take a monthly plan. Committing to 3, 6 or 12 months saves 5%, 7.5% or 10%. Every invoice is in INR with GST, so you can claim input tax credit.

Each plan includes a generous monthly bandwidth allowance, and we don't bill per GB of outbound traffic within it. If you consistently exceed it, we'll talk to you about a larger allocation before any overage appears.

Servers run in Indian data centres and your data stays in India unless you choose otherwise — useful for DPDP Act obligations and for low latency to Indian users.

Tenants are isolated at the hypervisor, every server gets a stateful virtual firewall and upstream anti-DDoS, and our operations are ISO 27001 certified with 24×7 NOC and SOC oversight. Acronis Cyber Protect adds backup and anti-malware if you want it.

A 99.95% uptime SLA on the platform, backed by redundant power, cooling, network and host hardware, with service credits if we miss it.

Yes, and it's free when you move to XcellHost. We assess the current setup, write a cut-over plan, rehearse it on a copy, and switch over out of hours so users barely notice.

Yes. Deploy Docker hosts or a K3s cluster from the one-click catalogue, connect nodes over private networking, and put a load balancer in front.

Yes — start on hourly billing with no lock-in, prove the workload, and move to a monthly or term plan once you're happy. Ask us about a guided proof-of-concept for larger migrations.

24×7 support by phone, WhatsApp and ticket from XcellHost engineers in Mumbai, in English and Hindi. It's included with every plan — there's no paid tier to unlock a human.
