Choosing where to host an enterprise application is one of those decisions that feels straightforward until you actually sit down and work through the options. There are more choices available now than at any point in the last twenty years, which is broadly a good thing — but it also means there is more room to get it wrong.
I have deployed applications on everything from a single physical server under a desk (do not judge — it was the early 2000s) to global Azure deployments spanning multiple regions. Here is what I have learned about making the right choice.
The Options at a Glance
Before diving into the detail, here is a high-level comparison of the main hosting approaches for enterprise workloads:
| Factor | Dedicated Server | VPS | Shared Hosting | Azure | AWS |
|---|---|---|---|---|---|
| Upfront cost | High | Low | Very low | None | None |
| Monthly cost | Medium-High | Low-Medium | Low | Variable | Variable |
| Scalability | Poor | Limited | Poor | Excellent | Excellent |
| Control | Full | Good | Limited | Good | Good |
| Management overhead | High | Medium | Low | Low-Medium | Low-Medium |
| .NET integration | Manual | Manual | Limited | Native | Good |
| Reliability (SLA) | Depends on provider | Moderate | Low | 99.95%+ | 99.99%+ |
Dedicated Servers
There was a time when a dedicated server was the obvious choice for anything business-critical. You got your own hardware, full root access, and complete control over the configuration.
Where they still make sense:
- Applications with predictable, constant workloads that do not need to scale up and down
- Situations where data sovereignty requirements mean you need to know exactly where your hardware sits
- Legacy applications that are tightly coupled to specific OS or software versions
Where they fall short:
- Scaling means buying and provisioning new hardware, which takes days or weeks
- You are responsible for everything: patching, backups, hardware failures, network configuration
- Disaster recovery requires a second physical location with duplicate infrastructure
For most new enterprise projects, I would not recommend dedicated servers as a first choice unless there are specific compliance or performance reasons driving the decision.
VPS and Shared Hosting
Virtual private servers occupy a middle ground. You get your own isolated environment without the cost of dedicated hardware. For smaller applications or development environments, they work well enough.
Shared hosting, on the other hand, has no place in enterprise software. I mention it only because I still occasionally encounter businesses running critical applications on shared hosting plans. If that describes your situation, moving to something more appropriate should be a priority.
The Cloud Platforms: Azure and AWS
This is where most of the conversation sits these days, and rightly so. Both Azure and AWS offer genuine advantages for enterprise applications.
Microsoft Azure
For organisations building on the Microsoft stack — and that covers the vast majority of our clients — Azure is the natural choice. The integration between Visual Studio, .NET, SQL Server, and Azure is seamless in a way that AWS simply cannot match for Microsoft workloads.
Specific advantages for .NET applications:
- Azure App Service lets you deploy ASP.NET applications with minimal configuration. CI/CD pipelines from Azure DevOps or GitHub Actions work out of the box.
- Azure SQL Database is managed SQL Server. You get automatic backups, patching, and scaling without employing a DBA. For many of our clients, this alone justifies the move.
- Azure Active Directory integration means single sign-on and identity management tie directly into existing corporate infrastructure.
- Hybrid connectivity through Azure ExpressRoute or VPN gateways allows gradual migration rather than a risky big-bang approach.
The pricing model takes some getting used to. Azure costs are variable by nature, and if you do not configure spending alerts and right-size your resources, bills can surprise you. I always recommend starting with a thorough cost estimate using the Azure Pricing Calculator and reviewing actual spend monthly for the first six months.
Amazon Web Services
AWS has the larger market share overall and a broader range of services. If you are running Linux workloads, containerised applications, or have a team with existing AWS expertise, it is an excellent platform.
For .NET workloads specifically, AWS has improved significantly in recent years. You can run .NET applications on Elastic Beanstalk or ECS, and SQL Server runs perfectly well on RDS. But the tooling and integration will always feel slightly less native than Azure for Microsoft technology.
Where AWS has the edge:
- Global infrastructure is marginally more extensive in some regions
- Certain specialist services (particularly around machine learning and IoT) have more mature offerings
- Pricing for compute-heavy workloads can be more competitive with reserved instances
Making the Decision
In practice, the decision often comes down to a few key questions:
1. What is your technology stack?
If you are a Microsoft shop running .NET, SQL Server, and Active Directory, Azure is the path of least resistance. The native integration saves significant development and operational time.
If your stack is mixed or Linux-heavy, AWS or a multi-cloud approach might make more sense.
2. What does your team know?
The best platform is one your team can actually operate. If your infrastructure engineers have five years of AWS experience, switching to Azure for a single project introduces risk. Factor in the learning curve and the cost of mistakes made during that curve.
3. What are your compliance requirements?
Both Azure and AWS offer extensive compliance certifications, but the specifics vary. For UK public sector work, Azure generally has a slight advantage with its UK Government certification and UK-based data centres. Check the specifics for your industry.
4. What is your budget model?
Cloud platforms shift expenditure from capital to operational. For some organisations, this is a significant advantage. For others — particularly those with existing hardware investments — the transition needs careful financial planning.
A Word on Multi-Cloud
There is a trend towards multi-cloud strategies, running workloads across Azure and AWS simultaneously. For very large organisations with specific resilience requirements, this can make sense. For most mid-sized enterprises, it adds complexity without proportional benefit. You end up needing expertise in two platforms, two sets of tooling, and two billing models.
My recommendation: pick one primary platform and use it well. You can always introduce a second platform later if genuine requirements emerge.
Our Recommendation
For the majority of our clients — organisations running enterprise applications on Microsoft technology — Azure is the right choice. The integration is superior, the UK data centre presence is strong, and Microsoft’s investment in the platform shows no sign of slowing.
That said, the right answer depends on your specific circumstances. If you are evaluating hosting options for an enterprise application and want an honest assessment, we are always happy to have that conversation. No hard sell — just practical advice based on what we have seen work over the years.
