You do not have permission to edit this page, for the following reasons:

This IP address has been blocked from editing Wikipedia.
This does not affect your ability to read Wikipedia pages.
Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 34.205.0.0/16 has been blocked (disabled) by ‪ST47‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider. To prevent abuse, web hosts may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a web host's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and they should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 05:44, 30 September 2026.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

((Governance))
'''SOA Governance''' is a set of processes used for activities related to exercising control over services in a [[service-oriented architecture]] (SOA). One viewpoint, from IBM <ref>IBM SOA pages, [http://www-01.ibm.com/software/solutions/soa/gov/ Definition of SOA Governance]</ref> and others, is that SOA governance is an extension (subset) of [[IT governance]] which itself is an extension of [[corporate governance]]. The implicit assumption in this view is that services created using SOA are just one more type of IT asset in need of governance, with the corollary that SOA governance does not apply to IT assets that are "not SOA". A contrasting viewpoint, expressed by blogger Dave Oliver <ref>Dave Oliver's Blog, [http://geekswithblogs.net/SabotsShell/archive/2007/02/04/105428.aspx What is SOA Governance?]</ref> and others, is that service orientation provides a broad organising principle for all aspects of IT in an organisation — including IT governance. Hence SOA governance is nothing but IT governance informed by SOA principles. 

The focus of SOA governance is on those resources to deliver value to the business.<!-- what other ones are there? --> SOA systems require IT support processes as well as organizational processes that will also involve the business leaders. SOA needs a solid foundation that is based on standards and includes policies, contracts, and service level agreements. The IT community is expected to use services to quickly automate new and changing business processes. To do so, services should be produced with several design qualities, such as composability, loose-coupling, autonomy, data representation standardization. In addition, a SOA governance infrastructure should be in place to support the service delivery life-cycle, which includes a registry of services to enable service discovery. Consequently, SOA increases the need for [[good governance]] as it will help assign decision-making authorities, roles, and responsibilities and bring focus to the organizational capabilities needed to be successful.

== Definition ==
The definitions of SOA governance agree in its purpose of exercising control, but differ in the responsibilities it should have. Some narrow definitions focus on imposing policies and monitoring services, while other definitions use a broader business-oriented perspective.

Anne Thomas Manes defines governance as: “The processes that an enterprise puts in place to ensure that things are done [...] in accordance with best practices, architectural principles, government regulations, laws, and other determining factors. SOA governance refers to the processes used to govern adoption and implementation of SOA.”
<ref>Anne Thomas Manes, [http://www.intelligententerprise.com/showArticle.jhtml?articleID=164301126&pgno=3 The Elephant Has Left The Building], 1 July 2005</ref>

The specific focus of SOA governance is on the development of services that add value to the business, effective SOA governance must cover the people, processes, and technologies involved in the entire SOA life cycle from business point of view and connectivity and reuse from IT point of view, thus aligning business with IT. 

To quote Anne Thomas Manes again: “SOA is about behavior, not something you build or buy. You have to change behavior to make it effective.”
<ref>Philip J. Windley, [http://akamai.infoworld.com/pdf/special_report/2006/04SRsoagov.pdf SOA Governance: Rules of the Game] ((webarchive|url=https://web.archive.org/web/20080724200254/http://akamai.infoworld.com/pdf/special_report/2006/04SRsoagov.pdf |date=2008-07-24 )), InfoWorld.com, 23 January 2006</ref>

[[Gartner]] defines SOA Governance as “Ensuring and validating that assets and artifacts within the architecture are acting as expected and maintaining a certain level of quality.” <ref>Gartner, Magic Quadrant for SOA Governance, 2007</ref>

[[ISO 38500]] describes a framework with six guiding principles for corporate governance of information technology and a model for directors to govern IT with three main tasks: evaluate, direct and control. ISO 38500 differentiates between "Governance", "Management" and "Control".

== Scope  ==
Some typical governance issues that are likely to emerge in a SOA are:
* ''Delivering value to the stakeholders'': investments are expected to return a benefit to the stakeholders - this is equally true for SOA.
* ''Compliance to standards or laws'': IT systems require auditing to prove their compliance to regulations like the [[Sarbanes–Oxley Act]]. In a SOA, service behavior is often unknown.
* ''Change management'': changing a service often has [[unforeseen consequence]]s as the service consumers are unknown to the service providers. This makes an impact analysis for changing a service more difficult than usual.
* ''Ensuring quality of services'': The flexibility of SOA to add new services requires extra attention for the quality of these services. This concerns both the quality of design and the quality of service. As services often call upon other services, one malfunctioning service can cause damage in many applications.
Some key activities that are often mentioned as being part of SOA governance are:
* Managing the portfolio of services: planning development of new services and updating current services
* Managing the service lifecycle: meant to ensure that updates of services do not disturb current service consumers
* Using policies to restrict behavior: rules can be created to which all services must conform, ensuring consistency of services
* Monitoring performance of services: because of service composition, the consequences of service downtime or underperformance can be severe. By monitoring service performance and availability, action can be taken instantly when a problem occurs.
* Managing how and by whom services are used<ref>Wohl Associates, SOA Governance An IBM White Paper, October 2006 (http://www-01.ibm.com/software/solutions/soa/Amy_Wohl_SOA_Governance_Analyst_White_Paper.pdf)</ref>
