Hosted infrastructure services and IaaS
Some applications need control of the operating system and installed software. Infrastructure as a Service can provide cloud computing, storage and networking while leaving you that control.
We help assess whether it suits your workload and the work needed to run it. Supplying resources and managing the systems on them are separate parts of the decision.

Choose IaaS for a reason, not just a different location
An application may need a particular server configuration or access that a managed application platform does not offer. That can make IaaS a useful option, provided the software, licences and dependencies fit the proposed environment.
Simply recreating an existing server in the cloud can move its old problems into a new billing arrangement. We look at what the workload actually needs and where the current design may need attention before it is moved.
A larger virtual machine is not the answer to everything
Storage behaviour, network paths and data movement can matter as much as processor or memory capacity. Resource choices need to reflect peak demand and how the application uses the infrastructure around it.
Consider consumption alongside availability and growth. Some resources run continuously, others vary with demand, and some charges sit outside the headline computing cost. The design needs to make that wider picture understandable.

Put names against the work above the physical infrastructure
The provider operates the underlying infrastructure, but the systems you deploy still need care. Operating-system maintenance, installed applications, access controls and network configuration do not lose their owners because the server is virtual.
Monitoring, incident investigation, backup and restoration also need to be assigned. Where Proxar is to carry out that work, we include it explicitly in the service. Cloud management explains the ongoing administration of customer-held environments.
Think about restoring the application, not just a machine
Recovery needs the data, dependencies and checks that make a service usable again. Replacing a virtual machine may be only one step. Work through the business priorities and who will verify the restored application before relying on the plan.
Platform as a Service may remove some operating tasks where the application fits its capabilities. Comparing that option with IaaS is about control, compatibility and continuing work, not assuming one model is always simpler or better.

Before you decide
Your questions, answered
Would PaaS leave us with less to maintain?
It may remove some infrastructure and operating-system work, depending on the platform. The application must fit the supported features, versions and limits. You still need owners for application configuration, access, data and other retained responsibilities. We compare those practical differences against the workload rather than assume PaaS is automatically the right choice.
Can IaaS come with a managed service?
Yes. Resources can be combined with agreed management, support and maintenance work. The proposal needs to identify exactly which layers are covered, including applications and recovery where relevant. The term IaaS on its own describes a resource model, not a complete promise to operate everything deployed on it.
Can we move an existing server without changing it?
That depends on the software, licensing, compatibility and dependencies. An apparently straightforward move can carry over unsupported components or inefficient resource use. We review the workload before choosing the approach so the migration does not simply relocate a known problem without addressing its cause.
Does cloud hosting remove the need for a recovery plan?
No. You still need to know how a usable application and its data would be restored, who can perform that work and how the result is checked. Backup and recovery responsibilities depend on the services selected. They should be reviewed against the business requirements rather than assumed from the hosting location.
