IaaS, PaaS, SaaS & VPNaaS cloud deployments
Public cloud for scale, private cloud for control, hybrid for both. Changing Technologies designs, migrates, secures and manages cloud infrastructure, platforms, applications and VPN as a Service, sized to your workloads, budget and security requirements.

The four service models, public versus private cloud, and how we move workloads without disrupting your business. Click a chapter to jump to it.
Cloud services
Most organizations use a mix. We help you decide what belongs where, then build it with security, identity, backup and monitoring in place from day one.
On-demand virtual machines, storage and networking, without buying hardware.
Build and run applications while the provider manages servers, patching and runtime.
Business applications delivered in the browser, licensed per user and always current.
Replace aging VPN appliances with cloud-delivered, zero-trust remote access.
The service model decides where your responsibility ends and the provider's begins. Security of your data and identities always stays with you, and CTI helps you carry it.
| Layer | On-premises | IaaS | PaaS | SaaS |
|---|---|---|---|---|
| Data, users & access | You | You | You | You |
| Applications | You | You | You | Provider |
| Runtime & middleware | You | You | Provider | Provider |
| Operating system | You | You | Provider | Provider |
| Servers, storage & network | You | Provider | Provider | Provider |
| Datacenter & power | You | Provider | Provider | Provider |
Public & private cloud
We place each workload where it runs best, based on performance, compliance, cost and how fast it needs to grow.
Public cloud
Private cloud
Hybrid cloud
We deploy and manage Azure virtual machines, storage and file shares, virtual networks, managed databases, app hosting and Kubernetes, with Microsoft Entra ID for identity and single sign-on. Start pay-as-you-go and scale as demand grows.
Run your virtual machines on high-availability clusters with enterprise SAN storage, full console access and scheduled backups, in geographically diverse data centers. Bring an existing VM, or let us convert physical servers for you.
How we deliver
Every deployment includes backup, monitoring and a recovery plan we actually test.
Inventory servers, apps, data and users. Map dependencies, costs and compliance needs.
Choose IaaS, PaaS, SaaS or VPNaaS per workload, and design identity, network and security.
P2V conversions, VM and data moves, and Microsoft 365 migrations, scheduled around your business.
Monitoring, patching, cost reviews, backup checks and help desk support after go-live.

Questions
IaaS rents you the infrastructure (virtual machines, storage, networking) and you manage the operating system up. PaaS adds a managed platform so you only deploy your application and data. SaaS is a finished application, such as Microsoft 365, that you simply sign in to and use.
A cloud-delivered replacement for the traditional VPN appliance. Users connect through the provider's network, and access to each application is granted by identity, device health and policy (zero trust) instead of by being "inside" the office network.
It depends on the workload. Variable or fast-growing workloads usually fit public cloud such as Microsoft Azure. Steady, sensitive or legacy workloads often run better and cost less on dedicated private cloud hosting. Many organizations use both, in a hybrid design.
Yes. We convert physical Windows and Linux servers to virtual machines (P2V), test them, and then run them on private cloud hosting, in Azure or back on your own hardware.
Always. Cloud providers keep their platforms running, but protecting your data is your responsibility. Every CTI deployment includes backup, monitoring and a tested recovery plan.
