In telecommunication, provisioning is the process of preparing and equipping a network to allow it to provide (new) services to its users. In NS/EP telecommunications services, "provisioning" equates to "initiation" and includes altering the state of an existing priority service or capability.
Network provisioning or service mediation are terms referring to provisioning of the customer’s services to the network elements, mostly used in the telecommunication industry. It requires the existence of networking equipment and depends on network planning and design.
In a modern signal infrastructure employing information technology at all levels, there is no distinction possible between telecommunications services and "higher level" infrastructure. Accordingly, provisioning configures any required systems, provides users with access to data and technology resources, and refers to all enterprise-level information resource management involved.
- give users access to data repositories or grant authorization to systems, network applications and databases based on a unique user identity, and
- appropriate for their use of hardware resources, such as computers, mobile phones and pagers.
As its most central responsibility, the provisioning process monitors access rights and privileges to ensure the security of an enterprise's resources and user privacy. As a secondary responsibility, it ensures compliance and minimizes the vulnerability of systems to penetration and abuse. As a tertiary responsibility, it tries to reduce the amount of custom configuration using boot image control and other methods that radically reduce the number of different configurations involved.
"Provisioning" often appears in the context of virtualization, orchestration, utility computing, cloud computing, and open configuration concepts and projects. For instance, the OASIS Provisioning Services Technical Committee (PSTC) defines an XML-based framework for exchanging user, resource, and service provisioning information, e.g. SPML (Service Provisioning Markup Language) for "managing the provisioning and allocation of identity information and system resources within and between organizations".
Once provisioned, the process of SysOpping ensures that services are maintained to the expected standards. Provisioning thus refers only to the setup or startup part of the service operation, and SysOpping to the ongoing responsibility.
Network provisioning 
The services which are assigned to the customer in the customer relationship management (CRM) have to be provisioned on the network element which is enabling the service and allows the customer to actually use the service. The relation between a service configured in the CRM and a service on the network elements is not necessarily a 1:1 relation. Some services can be enabled by more than one network element, e.g. the Microsoft Media Server (mms://) service.
During the provisioning, the service mediation device translates the service and the corresponding parameters of the service to one or more services/parameters on the network elements involved. The algorithm used to translate a system service into network services is called provisioning logic.
Electronic invoice feeds from your carriers can be automatically downloaded directly into the core of the telecom expense management (TEM) software and it will immediately conduct an audit of each single line item charge all the way down to the User Support and Operations Center (USOC) level. The provisioning software will capture each circuit number provided by all of your carriers and if bills outside of the contracted rate an exception rule will trigger a red flag and notify the pre-established staff member to review the billing error.
Server provisioning 
Server provisioning is a set of actions to prepare a server with appropriate systems, data and software, and make it ready for network operation. Typical tasks when provisioning a server are: select a server from a pool of available servers, load the appropriate software (operating system, device drivers, middleware, and applications), appropriately customize and configure the system and the software to create or change a boot image for this server, and then change its parameters, such as IP address, IP Gateway to find associated network and storage resources (sometimes separated as resource provisioning) to audit the system. By auditing the system, you ensure OVAL compliance with limit vulnerability, ensure compliance, or install patches. After these actions, you restart the system and load the new software. This makes the system ready for operation. Typically an internet service provider (ISP) or Network Operations Center will perform these tasks to a well-defined set of parameters, for example, a boot image that the organization has approved and which uses software it has license to. Many instances of such a boot image create a virtual dedicated host.
There are many software products available to automate the provisioning of servers, services and end-user devices. Examples: HP Server Automation, IBM Tivoli Provisioning Manager, Redhat Kickstart, xCAT, etc. Middleware and applications can be installed either when the operating system is installed or afterwards by using an Application Service Automation tool. Further questions are addressed in academia such as when provisioning should be issued and how many servers are needed in multi-tier, or multi-service applications.
In cloud computing servers may be provisioned via a web user interface or an application programming interface. One of the unique things about cloud computing is how rapidly and easily this can be done. Monitoring software can be used to trigger automatic provisioning when existing resources become too heavily stressed.
In short, server provisioning configures servers based on resource requirements. The use of a hardware or software component (e.g. single/dual processor, RAM, HDD, RAID controller, a number of LAN cards, applications, OS, etc.) depends on the functionality of the server, such as ISP, virtualization, NOS, or voice processing. Server redundancy depends on the availability of servers in the organization. Critical applications have less downtime when using cluster servers, RAID, or a mirroring system.
Service used by most larger scale centers in part to avoid this. Additional resource provisioning may be done per service.
User provisioning 
User provisioning refers to the creation, maintenance and deactivation of user objects and user attributes, as they exist in one or more systems, directories or applications, in response to automated or interactive business processes. User provisioning software may include one or more of the following processes: change propagation, self-service workflow, consolidated user administration, delegated user administration, and federated change control. User objects may represent employees, contractors, vendors, partners, customers or other recipients of a service. Services may include electronic mail, inclusion in a published user directory, access to a database, access to a network or mainframe, etc. User provisioning is a type of identity management software, particularly useful within organizations, where users may be represented by multiple objects on multiple systems.
Self-service provisioning for cloud computing services 
On-demand self-service is described by the National Institute of Standards and Technology (NIST) as an essential characteristic of Cloud computing. The self-service nature of cloud computing lets end users obtain and remove cloud services―including applications, the infrastructure supporting the applications, and configuration― themselves without requiring the assistance of an IT staff member. Cloud users can obtain cloud services through a cloud service catalog or a self-service portal. Because business users can obtain and configure cloud services themselves, this means IT staff can be more productive and gives them more time to manage cloud infrastructures.
Mobile subscriber provisioning 
This refers to the setting up of new services, such as GPRS, MMS and Instant Messaging for an existing subscriber of a mobile phone network, and any gateways to standard Internet chat or mail services. The network operator typically sends these settings to the subscriber's handset using SMS or WAP as mobile operating systems accept.
A typical example of provisioning is the BlackBerry services. A mobile user who is using voice services wishes to switch to BlackBerry services as his emails and data is very crucial for him to carry, his BlackBerry services are "provisioned" and thus he is able to stay connected through push emails and other features of BlackBerry services.
Device Management players such as Sicap ensures that end-users benefit from plug and play data services, whatever device they are using. Such a platform automatically detects devices in the network and sends them settings for immediate and continued usability. The process is fully automated, keeps history of used devices and sends setting only to subscriber devices which were not previously set. Sicap DMC ( Device Management Centre ) achieves this by filtering IMEI/IMSI pairs. Some operators ( see example from Vimpelcom Group subsidiary Kartel) report DM activity of 50 over-the-air settings update files per second.
Mobile content provisioning 
This refers to delivering mobile content, such as mobile internet to a mobile phone, agnostic of the features of said device. These may include operating system type and versions, Java version, browser version, screen form factors, audio capabilities, language settings and a plethora of other characteristics. As of April 2006, an estimated 5000 permutations are relevant. Mobile content provisioning facilitates a common user experience, though delivered on widely different handsets.
Internet access provisioning 
When getting a user / customer online, beyond user provisioning and network provisioning, the client system must be configured. This process may includes many steps, depending on the connection technology in question (DSL, Cable, Fibre, etc.). The possible steps are:
- modem configuration
- authentication with network
- install drivers
- setup Wireless LAN
- secure operating system (primarily for Windows only)
- configure browser provider-specifics
- e-mail provisioning (create mailboxes and aliases)
- e-mail configuration in client systems
- install additional support software
- install add-on packages purchased by the customer
There are four approaches to provisioning an internet access:
- Hand out manuals. Manuals are a great help for experienced users, but inexperienced users will need to call the support hotline several times until all internet services are accessible. Every unintended change in the configuration, by user mistake or due to a software error, results in additional calls.
- On-site setup by a technician. Sending a technician on-site is the most reliable approach from the provider’s point of view, as the person ensures that the internet access is working, before leaving the customer’s premises. This advantage comes at high costs – either for the provider or the customer, depending on the business model. Furthermore it is inconvenient for customers, as they have to wait until they get an installation appointment and because they need to take a day off from work. For repairing an internet connection on-site or phone support will be needed again.
- Server-side remote setup. Server-side modem configuration uses a protocol called TR-069. It is widely established and reliable. At the current stage it can only be used for modem configuration. Protocol extensions are discussed, but not yet practically implemented, particularly because most client devices and applications do not support them yet. All other steps of the provisioning process are left to the user, typically causing lots of rather long calls to the support hotline.
- Installation CD. Also called a "client-side self-service installation" CD, it can cover the entire process from modem configuration to setting up client applications, including home networking devices. The software typically acts autonomously, i.e. it doesn’t need an online connection and an expensive backend infrastructure. During such an installation process the software usually also install diagnosis and self-repair applications that support customers in case of problems, avoiding costly hotline calls. Such client-side applications also open completely new possibilities for marketing, cross- and up-selling. Such solutions come from highly specialised companies or directly from the provider’s development department.
