OpenStack Cloud Hosting: Escape Vendor Lock-In and Cut Cloud Bills by Up to 40%

You know that feeling when you open your monthly cloud invoice and the number stares back at you like it's personally offended you? You're not alone. Somewhere between the compute charges, the storage fees, the bandwidth line item, and the DDoS protection add-on you had to buy separately, the bill quietly ballooned into something that needs its own spreadsheet to decode. That's the moment a lot of people start typing "openstack cloud hosting" into a search box, looking for a way off the treadmill.

And honestly, that search is the right instinct. OpenStack has been quietly running serious infrastructure for telecoms, research labs, retailers, and a growing crowd of developers and small-to-mid businesses for over a decade. The reason it keeps showing up in conversations about cost control and data sovereignty isn't hype. It's because the whole project was built around a simple idea: your cloud shouldn't own you.

This piece walks through what OpenStack cloud hosting actually gives you, why people choose it over the big hyperscalers, and how one provider in particular, Sharktech, has turned that open-source foundation into a hosting product worth a serious look.

What OpenStack Cloud Hosting Actually Is

OpenStack is an open-source cloud operating system. Instead of one company owning the platform and locking you into proprietary APIs, pricing, and tooling, OpenStack is maintained by a global community and built on open standards. You get a set of services, each named after something memorable, that together let you manage compute, storage, and networking as a pooled, programmable resource.

The core services you'll hear about include Nova for compute, Cinder and Swift for block and object storage, Neutron for networking, and Keystone for identity. Together they expose RESTful APIs, which means you can automate pretty much everything, from spinning up a virtual machine to building out a full network topology, without ever touching a GUI if you don't want to.

In a hosted OpenStack setup, a provider runs the control plane and the physical infrastructure for you. You get the flexibility of a private cloud without the capital expense of buying servers, renting rack space, and hiring a team to keep it all alive. For anyone who has ever priced out a real on-premise deployment, that last sentence alone should be worth the price of admission.

Why People Keep Choosing OpenStack Over the Hyperscalers

The conversation around OpenStack vs AWS, Azure, or GCP usually comes down to a few things that show up again and again in independent comparisons and community discussions.

Cost predictability. Hyperscaler pricing is famously complex. Egress fees alone can turn a quiet month into a nasty surprise. OpenStack providers tend to bill more transparently, often with much lower outbound bandwidth charges and free inbound traffic. Independent TCO analyses, including ones published by Mirantis and DreamHost, consistently point to 25–40% savings once a workload scales past a few hundred virtual machines, and sometimes significantly more.

No vendor lock-in. Because OpenStack runs on open standards, your workloads, your images, and your automation scripts are portable. You're not rewriting your infrastructure code every time you think about moving. If you want to take your disk image and walk, you can.

Data control. For organizations that care about data sovereignty, regulatory compliance, or simply not having their workloads sitting inside a giant multi-tenant platform they can't fully inspect, OpenStack's multi-tenancy model and deployment flexibility matter. You can run it hosted, hybrid, or fully on your own hardware, and the same APIs work in all three.

Open-source economics. No expensive per-socket licensing fees baked into your bill. The platform is free; you pay for the infrastructure and the expertise to run it, which is exactly what a hosted provider handles for you.

A common pattern, and one that shows up repeatedly in community threads on Reddit and the OpenStack forums, is starting on a hyperscaler for speed and migrating to OpenStack once the bill gets serious. The math flips somewhere around sustained, predictable usage, and OpenStack is what people reach for when it does.

Where Sharktech Fits In

Sharktech is a Las Vegas-based infrastructure provider that has been running its own network since 2003. They operate as their own ISP (AS46844), peer at major Internet Exchange Points, and run five data centers across Los Angeles, Las Vegas, Denver, Chicago, and Amsterdam. Their OpenStack cloud is built on Virtuozzo Virtual Hybrid Infrastructure and is listed in the official OpenStack marketplace as a hosted private cloud option.

What makes Sharktech's OpenStack cloud worth a closer look isn't any single feature. It's the way a handful of decisions add up.

It's a real OpenStack, not a re-skinned VPS. You get the actual OpenStack APIs, the actual services, and the actual freedom that comes with them. You can upload your own qcow or ISO images, run your own cloud-init scripts, and download your disk images whenever you want. That last point is bigger than it sounds. It means there is no exit tax. Your data is yours, and you can prove it by pulling it off the platform any time you like.

Hyper-converged high availability. Your resources run across multiple servers and storage nodes simultaneously, so a hardware failure doesn't take your services down with it. Automatic failover and redundancy are built in, and Sharktech backs this with a 99.999% uptime guarantee on their cloud infrastructure.

Multi-tier storage you actually choose. Instead of being handed whatever storage the provider feels like giving you, you allocate between HDD, SSD, and NVMe based on what each workload needs. Estimated performance per volume, published by Sharktech, runs roughly 120MB/s and 3,000 IOPS for HDD, 350MB/s and 6,000 IOPS for SSD, and 1.2GB/s and 18,000 IOPS for NVMe. That's the difference between an archive bucket and a database that actually feels fast.

Networking that's simple but not dumb. Private networks, security groups, virtual routers with NAT, floating IPs, load balancers, integrated VPN for hybrid setups, and IPv4 plus IPv6 support are all part of the platform. The whole thing sits on a 40G/100G backbone with built-in DDoS scrubbing, which is not the kind of thing most OpenStack hosts include in the base price.

Developer-first by design. Full RESTful APIs across Nova, Cinder, Swift, Neutron, and Keystone mean anything you can do in the portal you can also do in code. Weekly-updated official Linux cloud images, support for custom Bash and cloud-init scripts at launch, and the ability to bring your own image make it a real platform for people who deploy with automation, not a web form.

Public Cloud vs Dedicated Cloud: Two Ways to Pay for the Same Platform

One of the more refreshing things about Sharktech's setup is that Public Cloud and Dedicated Cloud run on the exact same OpenStack infrastructure. The only difference is how you're billed. You pick the model that fits your workload, not the model that fits the provider's margin.

Public Cloud is the pay-as-you-go option. Each plan includes a fixed base of resources, and when you exceed that base you pay hourly for the extra. To keep you from accidentally lighting your budget on fire, plans (except Enterprise and Custom) come with a maximum resource cap, so your bill has a ceiling. This is the right pick for workloads with spiky or unpredictable demand, dev and test environments, and anything where you want the option to burst.

Dedicated Cloud is the prepaid model. You order a fixed pool of resources and pay a flat monthly rate for exactly that pool. If you pay for 8 cores, you get 8 cores, no more, no less, and no surprises. This is the right pick for steady-state production workloads where predictable billing matters more than the ability to burst.

Both models give you the full resource-pool approach that makes OpenStack hosting feel different from a traditional VPS. Instead of buying a fixed VM preset, you buy CPU, RAM, and storage that you can carve up across as many virtual machines as the pool allows. An allocation of 8 vCPUs, 8GB RAM, and 300GB SSD can be one big VM, four small ones, or anything in between, and you can redeploy it as your needs change.

How the Pricing Actually Works

Sharktech publishes hourly resource rates for the Public Cloud side, which makes it possible to estimate costs without guessing. The rates currently listed on their cloud page are:

• CPU: $0.0025 per core per hour

• RAM: $0.0035 per GB per hour

• NVMe storage: $0.000090 per GB per hour

• SSD storage: $0.000060 per GB per hour

• HDD storage: $0.000020 per GB per hour

On top of that, bandwidth is unlimited inbound and includes 5,000GB outbound per month, with additional outbound billed at $0.002 per GB. Every cloud service comes with one free public IPv4 address, and additional IPv4 addresses are $1.50 per month each. That ingress-free, low-egress model is a direct counter to the hyperscaler bandwidth fees that catch so many people off guard.

Sharktech states that their cloud delivers at least 40% cost savings compared to AWS, Azure, or GCP for equivalent configurations, and their public cloud pricing page goes further, claiming 50–80% savings in many cases. Those are provider claims, but they line up with what independent OpenStack-vs-hyperscaler TCO analyses have found at scale.

For the Dedicated Cloud side, pricing is a fixed monthly rate based on the resource pool you choose. If you need something beyond the standard tiers, including higher compute, storage, or network capacity, Sharktech's sales team will put together a custom quote.

Public Cloud Plans at a Glance

The Public Cloud line ranges from a starter tier up to Enterprise and Custom configurations. Here's how the main tiers break down, based on what Sharktech publishes on their cloud page.

Small. The entry point, starting at $7.95 per month. Designed for testing, staging, and light workloads where you want the OpenStack platform without committing to a large resource pool. Good for a developer spinning up their first cloud VM or running a small internal tool.

Medium. A step up in committed resources for production workloads that need more headroom but still benefit from the pay-as-you-go ceiling. Suitable for a small web application, a modest database, or a CI runner.

Large. More CPU, RAM, and storage for heavier applications, multi-service deployments, or busier production environments. The resource cap still applies, so you keep the predictability of the Public Cloud model.

Enterprise. The top standard tier, configured for serious workloads. Third-party listings put this around 64 CPU cores, 128GB RAM, 5TB SSD storage, and 20TB of outgoing bandwidth, at roughly $499 per month, though you should confirm exact specs and pricing on the order page since configurations can shift. This is where the Public Cloud model stops capping resources and you get full scalability.

Custom. When none of the standard tiers fit, Sharktech's sales team will build a plan around your specific compute, storage, and network requirements. This is also the route for anyone who wants a tailored SLA or a particular deployment across specific data centers.

Dedicated Cloud Plans at a Glance

If predictable monthly billing is more your style, the Dedicated Cloud side offers fixed resource pools billed at a flat monthly rate. The tiers run from small starter pools up to large production-grade allocations.

Tiny. The smallest Dedicated Cloud pool, for a single lightweight workload or a dev environment that you want on a fixed bill. Same OpenStack platform, same features, just a smaller commitment.

Small. A modest bump in resources for a small production app or a handful of internal services. Good fit for a startup that wants predictable cloud costs from day one.

Medium. A mid-range pool that can host several VMs across a small fleet of services. Suitable for a growing team that needs staging and production side by side under one bill.

Large. A serious pool for production workloads that need consistent performance and no surprises. The kind of tier you pick when downtime costs you money and you want the Dedicated Cloud's fixed-resource guarantee.

Huge, Giant, and Colossal. The upper end of the Dedicated Cloud line, for organizations running dense multi-VM environments, larger applications, or infrastructure that needs to scale horizontally within a fixed budget. Exact specs and pricing for these tiers are configured at order time, so confirm the current numbers on the deployment page.

The DDoS Protection Angle

This is the part where Sharktech genuinely separates from most OpenStack hosts. Their entire network was built around the assumption that attacks are routine, not edge cases. Every cloud plan includes built-in DDoS scrubbing as part of the base price, not as a paid add-on or a "contact us for a quote" line item.

Their global network capacity runs into the terabit range, traffic is scrubbed at the edge using BGP and Anycast, and the standard protection per IP is 60Gbps, which covers the vast majority of real-world volumetric attacks. For larger targets, 100Gbps protection is available, and enterprise deployments can go higher. If your workload is anything that attracts malicious traffic, game servers, fintech endpoints, public APIs, anything exposed to the open internet, this matters a lot more than a marketing bullet point suggests.

The Cloud Accelerator Program

For MSPs, SMBs, and startups thinking about migrating onto OpenStack, Sharktech runs a Cloud Accelerator Program that's worth knowing about. It includes a free current-infrastructure assessment, strategic cloud planning, a cloud migration blueprint, public or private cloud setup, and cloud credits to help offset the move. The consultation is free, and it's a genuinely useful starting point if you're trying to figure out whether a migration makes financial sense before you commit to anything.

Who This Is Really For

OpenStack cloud hosting in general, and Sharktech's version of it in particular, is a strong fit for a few specific crowds.

Developers and DevOps teams who want real APIs, real automation, and the ability to bring their own images and scripts. If you deploy with Terraform, Ansible, or raw OpenStack CLI calls, you'll feel at home here.

SMBs and MSPs looking to escape hyperscaler pricing without giving up enterprise-grade infrastructure. The predictable billing, lower egress fees, and open-source foundation make the math work in a way it often doesn't on the big platforms.

Teams migrating off AWS, Azure, or GCP because the bills got out of hand. Sharktech's 40%+ savings claim, their no-exit-tax image portability, and their migration support are all aimed squarely at this scenario.

Anyone running DDoS-prone workloads. Game servers, public-facing APIs, fintech, and anything that gets attacked regularly. The built-in protection is not a checkbox here, it's the foundation the company was built on.

Organizations that care about data sovereignty and avoiding lock-in. OpenStack's open standards and Sharktech's "your data is always yours" policy mean you can pull your images and walk at any time, with no proprietary format to convert and no exit fees to pay.

It's less of a fit if you need a fully managed platform where someone else handles your OS patches, your database tuning, and your application stack. Sharktech's cloud is self-managed by design. The support team is technically competent and available 24/7, but they're not going to administer your servers for you. If you want hand-holding through basic Linux, this isn't the product. If you want real infrastructure at an honest price with the keys handed to you, it is.

The Bottom Line

OpenStack cloud hosting exists for a reason, and that reason is that the hyperscaler model has a ceiling. Once your workload is big enough, predictable enough, or sensitive enough, the open-source path starts to make more sense on cost, on control, and on portability. The trick has always been finding a provider that runs it well, prices it honestly, and doesn't quietly strip out the features that make OpenStack worth running in the first place.

Sharktech checks those boxes. Real OpenStack APIs, hyper-converged high availability, multi-tier storage, a real network with real DDoS protection, transparent hourly or fixed pricing, no vendor lock-in, and a track record that goes back over two decades. If "openstack cloud hosting" is what brought you here, this is one of the better places that search will lead you.
