What is IT Infrastructure Hosting?

The services are acquired from external service providers, including off-site backup, website hosting, cloud services, backup services, virtual desktops, and cloud services. Hosted services can be outbound or inbound. Outbound services are usually paid in nature and require a new collaboration. Inbound services, on the other hand, are in-house services. 

IT Infrastructure Hosting represents a managed or unmanaged hosting service that a person or company can use in business. Usually, the IT infrastructure hosting term is used when we talk about data centers and can be divided into Server/Computer Room IT Infrastructure Hosting, Private Data Centre Infrastructure Hosting, Managed Services/Vendor Owned Infrastructure Hosting, and Vendor/Carrier Neutral Colocation Infrastructure Hosting.

Types of Hosted Services

A hosted service from external sources will be either managed or unmanaged.

What is a Managed Service?

A managed service involves the user installing the application and run the program. The service provider will provide the server and OS, but ultimately, management, running, and installation are upon the end-user. 

What is Un-managed Services?

Un-managed services involve no headache of management. All you have to do is sign up for the service and keep going. An un-managed provider might charge higher, but it also has data backup and security allowances. 

Difference between hosted service & Cloud service

The Cloud computing model offers hosted services. In the public Cloud, tenants or multiple customers have access to a shared server. They use resources and public infrastructure as a service(IaaS). Hosted services can also be private. They are virtualized, scalable resources where not everyone is allowed to access.  

The hosted service and cloud service are very confusing terms. The hosted service can be physical or virtual, while cloud services are usually virtual, like online data recovery tools, SEO services, website development tools. These are all cloud-based services. 

Different variations of Hosted Services 

  1. SAAS – Software as a service.
  2. PaaS – Platform as a service 
  3. DRaaS- Disaster Recovery as a services 
  4. DaaS- Desktop as a service

IT Operating Models 

IT operating models have been categorized into three classes: 


Under the wholly-owned category, the organization holds the rights over hardware and can perform all the functions without any violation. 

Under the partially owned category, the organizations hold partial rights over hardware and cannot exercise any function without informing the third party. 

Under the outsourced category, the organizations outsource the tasks entirely, and the Third-party controls everything. 


The third-party has rights over the data center and platform; it operates and installs the necessary applications. 

Public Cloud 

IaaS, PaaS, and SaaS are the types under the public Cloud category.
