Colocation colocation

In colocation your hosting provider provides you (rack) space to place your own servers and it comes with metered or unmetered bandwidth.在colocation您的託管服務提供商為您提供（機架）空間的地方，您自己的服務器和它附帶的水錶或unmetered帶寬。 You are responsible for purchasing and configuring the server to your requirements.你是負責採購和配置服務器，以您的要求。 This offers maximum flexibility in configuring your hardware and software.這提供了最大的靈活性，配置您的硬件和軟件。 Conversely in some way it is also the hardest to configure or maintain.相反，在某種程度上，這也是最難的配置或維持。 You definitely need a good system administrator.你一定要有一個好的系統管理員。 It is also normally the lowest priced of the hosting types discussed here.這也是通常價格最低的主辦類型在這裡討論。 Your hosting provider is responsible for maintaining the networking layer and data center layer.您的託管服務提供商，是負責維護網絡層和數據中心層。 You are responsible for the operating system, application infrastructure and business process software.你是負責操作系統，應用基礎架構和業務流程的軟件。

Dedicated Web Hosting專用虛擬主機

Dedicated web hosting can be managed or unmanaged.專用虛擬主機可以管理或無人管理。 I am talking here about unmanaged dedicated web hosting .我在這裡談論非託管專用Web託管 。 Here your web hosting provider will sell you a certain hardware configuration along with bandwidth for a fixed monthly price.在這裡您的Web託管服務提供商將出售給您一定的硬件配置，隨著帶寬為每月固定的價格。 Normally they will configure the server with your preferred choice of operating system and some essential software like Apache or MySQL.通常他們會配置服務器與您的首選作業系統和一些必要的軟件一樣， Apache或MySQL的。 After the initial configuration, your are pretty much on your own.後的初始配置，您是非常對自己的。 You will even have to (in most cases) configure your own firewall.你甚至會要（在大多數情況下）配置自己的防火牆。 This is pretty flexible in terms of configuration as you can pretty much do anything on your own server.這是相當靈活的條款的配置作為您可以非常做任何事對您自己的服務器上。 You are on your own.您對您自己。 Your web hosting provider is responsible only for the device layer, networking layer and data center layer.您的Web託管服務提供商只負責設備層，網絡層和數據中心層。 They may do a operating system reload for a fixed fee.他們可能做的作業系統裝入一個固定的費用。 The pain with web hosting providers is that they will charge you every month for items with fixed cost like networking card or harddisk.疼痛與Web託管服務提供商的是，他們將收取你每個月都為項目的固定成本，像網絡卡或硬碟。 However a good dedicated web hosting provider will change your defective hardware components on a short notice.但是一個良好的專用Web託管服務提供商將改變您的有缺陷的硬件組件對在短期內，恕不另行通知。

Managed Web Hosting管理虛擬主機

I am explicitly talking here about managed dedicated web hosting.我很明確地在這裡談論管理的專用網絡託管。 Normally they cost significantly higher than unmanaged dedicated web hosting.通常他們的成本顯著高於非託管專用Web託管。 For example Rackspace few days ago gave me a quotation which is more than three times higher than a similar configuration from LayeredTech unmanaged dedicated web hosting offer.例如rackspace前幾天給我的報價是3倍以上高於類似配置從layeredtech非託管專用虛擬主機提供。

In addition to device, layer, networking layer and data center layer, managed web hosting also covers your application infrastructure layer (JBoss, Java EE, ASP.net, SQL Server, MySQL etc. ) and operating system layer (Fedora Core, Red Hat Enterprise Linux, Microsoft Windows etc.).此外，設備，層，網絡層和數據中心層的，有管理的虛擬主機也包括您的應用基礎設施層（ JBoss公司，華電子工程專輯， asp.net中， SQL Server ， MySQL和等）和操作系統層（淺頂軟呢帽核心，紅帽企業Linux ，微軟的Windows等） 。 As you go up in the spectrum of managed services you also potentially lose flexibility in selecting and changing your infrastructure.正如你去了，在頻譜的管理服務，你也可能失去彈性，在選擇和改變您的基礎設施。 Think shared web hosting on steroids.認為共用網絡託管類固醇。

Service is key to both managed web hosting and fully outsourced services.服務的關鍵是雙方管理網站託管和完全外包服務。

Full outsourced services全面外包服務

Fully outsourced service providers like IBM not only takes care of all of the above layers but also takes care of your Application layer and Business process layer.完全外包服務供應商如IBM ，不僅照顧到所有上述層，但也照顧到您的應用層和業務流程層。 In short you lose much control over your system for the benefit of someone else taking care of it for you.在短期內你失去控制，您的系統為造福別人照顧它給你。 If you make the right choice of service provider and have a good SLA agreement in place (ensure that there are sufficient penalty clauses in the agreement as vendors like IBM may not automatically add them) then you may be fine and can focus on your core competencies.如果您作出正確的選擇服務提供商和有一個良好的SLA協議，已到位（確保有足夠的懲罰條款在協議中，作為廠商，如IBM公司可能不會自動將它們添加） ，那麼您可能會被罰款，並可以更加專注於您的核心能力。

What to choose? 有什麼選擇呢？
What you choose depends upon your unique needs, infrastructural requirements and monetary capabilities.什麼您選擇，取決於您的特殊需求，基礎設施的要求和貨幣的能力。 Personally I prefer unmanaged dedicated servers with in-house dedicated system administrator to look after it.我個人喜歡非託管專用服務器，與在內部專用的系統管理員，以照顧它。
