CB4UHost is a vendor-neutral hosting comparison and IT services platform by W-Tech. We help you compare hosting options across shared, VPS, cloud, dedicated, GPU, and colocation — and we offer migration, managed services, security, AI infrastructure, and digital transformation services.

Are you affiliated with any hosting provider?

No. We don't resell hosting and we don't take affiliate commissions that bias our recommendations. Our revenue comes from consulting and managed services, not from pushing you toward a specific provider.

Which hosting types do you compare?

Six types: shared, VPS, cloud, dedicated, GPU cloud, and colocation. We compare them apples-to-apples on price, performance, support, and trade-offs.

Is the first consultation free?

Yes. The first 30-minute consultation is free. We'll assess your situation and recommend next steps — whether that's a paid engagement, the free Hosting Calculator, or just pointing you to the right provider.

How do you price engagements?

Most engagements are fixed-fee with defined deliverables. Managed services are month-to-month or annual. We don't do hourly billing — you should know the cost before we start. Typical ranges: migrations $2,000–$25,000, managed services $500–$5,000/month, AI/ML engagements $5,000–$50,000, security assessments $3,000–$15,000.

What is shared hosting and when should I use it?

Shared hosting means multiple websites share a single physical server's CPU, RAM, and storage. It is the cheapest option (typically $1.98–$8/month) but offers no dedicated resources. Use it for low-traffic blogs, brochure sites, personal portfolios, and small business landing pages where uptime and performance aren't mission-critical. Examples: Namecheap Stellar, Bluehost Basic.

What is VPS hosting and how is it different from shared?

VPS (Virtual Private Server) hosting gives you a dedicated slice of CPU and RAM via virtualization. You don't share resources with neighbors, so performance is predictable. Typical price: $4–$20/month. Choose VPS over shared when you need root access, custom software, predictable performance, or are running a SaaS MVP, staging environment, or growing site that has outgrown shared limits.

When should I move from VPS to cloud hosting?

Move to cloud hosting when you need auto-scaling (traffic spikes), pay-per-use billing, multi-region deployment, or managed databases and load balancers. Cloud is best for SaaS in production, spiky-traffic apps, and microservices architectures. Typical price: $8–$80/month. If your workload is steady and predictable, dedicated or VPS will usually be cheaper at the same performance level.

What is a dedicated server and who needs one?

A dedicated server is a whole physical server reserved for you alone. You get 100% of the CPU, RAM, disk, and network bandwidth. Typical price: $50–$500/month. Choose dedicated when you have predictable heavy workloads (large databases, data pipelines, game servers), strict compliance requirements (HIPAA, PCI-DSS), or workloads where the per-hour cost of cloud would exceed a flat monthly fee.

What is GPU cloud hosting used for?

GPU cloud hosting provides instances with NVIDIA or AMD GPUs (A100, H100, L40S, MI300X, etc.) for parallel compute workloads. Use cases: LLM training and fine-tuning, RAG inference, computer vision, video transcoding, scientific simulations (CFD, molecular dynamics), and 3D rendering. Pricing is typically per-hour: $0.50–$3.50/hour depending on GPU model. Providers we compare: CoreWeave, Lambda, RunPod, Vast.ai, AWS p4d, GCP A2/A3, Azure ND-series.

What is colocation and when does it make sense?

Colocation ('colo') means you own the hardware and rent space, power, cooling, and network in a carrier-grade data center. Typical price: $199–$2,000/month per rack unit. It makes sense when you already own expensive hardware, have sovereign data requirements, need specific certifications the cloud can't meet, or have a workload that's so steady that owning beats renting over 24–36 months. Examples: Equinix IBX, Digital Realty, NTT.

What AI and ML infrastructure services do you offer?

Our AI & ML Infrastructure practice covers: GPU cloud brokerage (comparing CoreWeave, Lambda, RunPod, Vast.ai, AWS, GCP, Azure for your workload), LLM fine-tuning on your data, RAG (retrieval-augmented generation) pipeline design, MLOps setup (model registry, CI/CD, monitoring), and production inference optimization. We're vendor-neutral — we benchmark providers against your actual workload, not affiliate payouts.

What does your migration service include?

Migration engagements cover four workstreams: infrastructure migration (servers, networking, DNS), application migration (code refactoring, containerization), data migration (databases, file stores, ETL pipelines), and email migration (Google Workspace, Microsoft 365, Zoho). Each migration includes a pre-migration assessment, runbook, cutover plan, rollback plan, and 30 days of post-migration hypercare. Typical engagement: 2–6 weeks, $2,000–$25,000 fixed-fee.

Do you offer 24/7 managed services?

Yes. Our Managed Services practice includes 24/7 NOC monitoring, patch management, backups (with tested restore drills), performance optimization, incident response, and quarterly business reviews. We support Linux (Ubuntu, RHEL, Debian), Windows Server, Kubernetes, and all major clouds (AWS, GCP, Azure, DigitalOcean, Hetzner). Pricing: month-to-month or annual, $500–$5,000/month per workload depending on complexity.

What security and compliance services do you provide?

Our Digital Security & Compliance practice offers: VAPT (Vulnerability Assessment and Penetration Testing) covering web, API, network, and cloud, ISO 27001 implementation and audit support, SOC 2 Type II readiness, GDPR and DPDP compliance reviews, and security architecture design (zero-trust, SASE, IAM). All assessments include a remediation roadmap. Typical VAPT: $3,000–$15,000 fixed-fee. ISO 27001 readiness: 3–6 months, $15,000–$40,000.

Can you help with DevOps and digital transformation?

Yes. Our Digital Transformation practice covers DevOps automation (CI/CD pipelines, GitOps, Infrastructure as Code with Terraform), containerization (Docker, Kubernetes, Helm), legacy application modernization (monolith to microservices), observability stacks (Prometheus, Grafana, OpenTelemetry), and platform engineering. We focus on knowledge transfer — your team leaves each engagement stronger, with runbooks and code you own.

Do you offer FinOps and cloud cost optimization?

Yes. Our FinOps service includes: a baseline audit of current cloud spend, identification of waste (idle resources, oversized instances, unattached volumes, egress charges), right-sizing recommendations, reserved instance / savings plan strategy, and a quarterly cadence to keep costs in check. Typical engagement saves 20–40% on cloud spend. Fixed-fee audit: $3,000–$8,000. Ongoing FinOps: $1,000–$3,000/month.

How does your hosting comparison methodology work?

Every comparison follows a 7-step methodology: (1) workload profiling, (2) provider shortlisting, (3) apples-to-apples normalization (per-spec, per-month, per-unit), (4) trade-off analysis (price vs. performance vs. support vs. lock-in), (5) 12-month and 36-month TCO calculation including migration and egress, (6) vendor-neutral recommendation, (7) optional paid migration plan. We publish the methodology so you can challenge any recommendation.

Which hosting providers do you compare?

We compare plans from: Namecheap, A2 Hosting, Contabo, Bluehost, CoreWeave, Equinix, AWS, Google Cloud, Microsoft Azure, DigitalOcean, Hetzner, OVHcloud, Lambda Labs, RunPod, Vast.ai, Vultr, Linode (Akamai), Hostinger, SiteGround, InMotion Hosting, and others. We add providers on request and based on market relevance. We do not accept payment from providers to be listed or featured.

How long does a typical migration take?

Migration timelines depend on workload complexity. A simple shared-to-VPS migration: 3–5 days. A monolith app to Kubernetes on cloud: 4–8 weeks. A multi-region database migration with zero downtime: 6–12 weeks. We give you a fixed timeline after the assessment phase, and we stick to it — every engagement includes a written cutover plan.

Do you sign NDAs and BPAs?

Yes. We sign mutual NDAs as standard before any technical discussion. For larger engagements we sign Business Partnership Agreements (BPAs) and Master Service Agreements (MSAs) with defined SLAs, escalation paths, and termination clauses. We carry professional indemnity insurance.

What regions do you operate in?

Primary: India, Middle East (UAE, Saudi Arabia), Southeast Asia (Singapore, Indonesia, Vietnam). Secondary (remote): US, EU, UK, Australia. We staff engagements across 4 time zones and offer follow-the-sun support for managed services clients. All engagements are delivered in English; Hindi and Arabic available on request.

What is the difference between cloud and VPS?

VPS gives you a fixed slice of one server — predictable but not elastic. Cloud gives you on-demand, auto-scaling resources across many servers — elastic but potentially more expensive. Choose VPS for steady, predictable workloads where cost control matters. Choose cloud for spiky traffic, microservices, and SaaS in production where elasticity is worth the premium.

How much does GPU cloud hosting cost per hour?

GPU cloud pricing per hour (as of 2025): NVIDIA A100 80GB ~$1.50–$3.50/hr (CoreWeave, Lambda), NVIDIA H100 80GB ~$2.50–$4.50/hr, NVIDIA L40S ~$1.00–$1.80/hr, NVIDIA A10G ~$0.75–$1.20/hr (AWS, GCP), AMD MI300X ~$2.00–$3.50/hr. Spot/preemptible pricing can be 50–70% lower. We compare real provider pricing in our Hosting Calculator.

What is RAG and do you implement it?

RAG (Retrieval-Augmented Generation) is an architecture that combines an LLM with a knowledge store (typically a vector database like Pinecone, Weaviate, or pgvector) so the model can cite your private data when answering. We implement RAG end-to-end: document ingestion, chunking strategy, embedding model selection, vector store setup, retrieval tuning, and production monitoring. Typical engagement: 4–8 weeks, $10,000–$40,000 fixed-fee.

What is TCO in cloud computing?

TCO (Total Cost of Ownership) is the full 12- or 36-month cost of running a workload, including compute, storage, network egress, support, migration, training, and opportunity cost. Cloud list prices understate TCO by 30–60% because they ignore egress, snapshots, NAT gateways, load balancers, and team time. We calculate real TCO for every comparison on CB4UHost.

What does VAPT stand for and what does it include?

VAPT stands for Vulnerability Assessment and Penetration Testing. VA is automated scanning to find known weaknesses (CVEs, misconfigurations, weak ciphers). PT is manual exploitation by a human tester to find business-logic flaws, privilege escalation, and chained exploits. Our VAPT covers web apps, APIs, networks, cloud configurations, and mobile apps. Deliverables: technical report, executive summary, remediation roadmap, and a retest after fixes. Typical cost: $3,000–$15,000.

How do I get started with CB4UHost?

Three ways: (1) Use the free Hosting Calculator to compare plans yourself, (2) Read our blog and knowledge base for vendor-neutral guides, (3) Book a free 30-minute consultation through the Contact page. After the consultation, if we can help, we send a fixed-fee proposal within 48 hours.

Do you work with startups or only enterprises?

Both. About 40% of our clients are seed-to-Series-B startups (typical engagement: migration, VPS-to-cloud, basic DevOps), 40% are mid-market (managed services, FinOps, security assessments), and 20% are enterprise (multi-cloud strategy, ISO 27001, AI infrastructure). Every engagement is scoped and priced individually after a free 30-minute consultation — no minimums, no hourly billing.

Real-World Scale — How Big Are These Providers, Really?

Our map shows publicly-disclosed region endpoints (one dot per region, not per physical building). Each region typically houses multiple datacenter facilities and availability zones. The numbers below are the actual provider-reported scales — so the 18 AWS dots you see above represent 900+ physical facilities.

Facility counts are industry estimates from provider sustainability reports and public filings. AWS, Azure, and GCP figures come from each provider's most recent sustainability disclosures. "Region" = a distinct geographic deployment area; each region contains 1-6 availability zones, and each availability zone contains 1+ physical datacenter buildings.

EstimatesPUE values from provider sustainability reports and industry estimates. Actual values may vary by season and load. Renewable energy % and grid carbon intensity are approximate.

About this tool

Where you host matters. A datacenter in Sweden running on hydro power has a fraction of the carbon footprint of one in Singapore running on natural gas — even if the cloud provider is the same. PUE (Power Usage Effectiveness) measures how efficient the datacenter building is; grid carbon intensity measures how clean the electricity is.

Our Global Datacenter Efficiency Map shows 284 cloud datacenters across 14 providers (AWS, GCP, Azure, Oracle, OVHcloud, DigitalOcean, Hetzner, IBM Cloud, Alibaba, Tencent, Linode/Akamai, Vultr, Scaleway, UpCloud) on a world map, color-coded by PUE.
