Website Hosting Uae
A website hosting service is a type of internet hosting service that allows individuals and companies to make their site available via the world wide web. Website hosts are organizations that supply space on a server owned or leased for use by clients, as well as providing internet connectivity, usually in a data center. Web hosts can also offer data center space and connectivity to the internet for other servers located in their data center, called colocation, also known as Housing in Latin America or France.
History
Until 1991, the internet was limited to use only "...for research and education in the sciences and engineering..." and was used for email, telnet, FTP and USENET traffic, but only a small number of website pages. The world wide web protocols had only just been created and not till the end of 1993 would there be a graphical website browser for Mac or Windows computers. Even after there was increased internet availability, the situation was convoluted until 1995.
To host a web site on the internet, an individual or company would need their own computer or server. As not all companies had the money or experience to do this, web hosting services began to supply services to host users' sites on their own servers, without the client needing to assemble the necessary infrastructure neededd to operate the web site. The owners of the sites, also referred to as webmasters, would be able to build a site that would be hosted on the web hosting service's server and published to the web by the website hosting service.
As the number of users on the internet grew, the pressure for companies, both big and tiny, to have an online presence increased. By 1995, companies such as GeoCities, Angelfire and Tripod were offering free hosting.
Classification
Smaller Hosting Services
The most simple is aweb page and small-scale file hosting, where files can be uploaded via File Transfer Protocol (FTP) or a website interface. The files are typically delivered to the web "as is" or with minimal processing. Many internet service providers (ISPs) provide this service free of charge to users. Individuals and companies may also get website page hosting from alternative service providers.
Free website hosting service is provided by various organizations with limited services, often supported by adds, and at times limited when compared to paid hosting.
Single page hosting is at times sufficient for personal web pages. Personal web site hosting is typically free, advertisement-sponsored, or inexpensive. Business web site hosting sometimes has a greater cost depending upon the size and type of the site.
Larger Hosting Services
Many large companies that are not internet service providers need to be constantly connected to the web so they can send email, files, etc. to other sites. The company may use the computer as a website host to provide details of their products and services and facilities for website orders.
A complicated site needs a more comprehensive package that supplies database support and application development platforms (e.g. ASP.NET, ColdFusion, Java EE, Perl/Plack, PHP or Ruby on Rails). These programs allow clients to create or install scripts for applications like forums and content management. Also, Secure Sockets Layer (SSL) is typically used for sites that wish to keep the data transmitted safe.
Types of Hosting
Internet hosting services can manage web servers. The scope of website hosting services differs a lot.
Shared Website Hosting Service
One's website is placed on the same server as many other sites, ranging from a few websites to hundreds of sites. Typically, all domains may share a common pool of server resources, such as RAM and the CPU. The features that are available with this kind of service can be fairly simple and not flexible in terms of software and updates. Resellers sometimes make available shared website hosting and website organizations at times have reseller accounts to provide hosting for clients.
Reseller Web Hosting
Reseller website hosting allows customers to be website hosts themselves. Resellers may function, for individual domains, under any combination of these types of hosting, depending on who they are affiliated with as a reseller. Resellers' accounts may differentiate quite a bit in size: they may have their own virtual dedicated server to a colocated server. Many resellers supply a nearly identical service to their provider's shared hosting plan and offer the technical support themselves.
Virtual Dedicated Server
This is also known as a Virtual Private Server (VPS), it separates server resources into virtual servers, where resources can be allocated in a way that does not directly reflect the server's hardware. VPS will at times be allocated resources based on a one server to many VPSs relationship, however, virtualization may be wanted for a number of reasons, which includes the ability to move a VPS container from one server to another. The users might have root access to their own virtual space. Users are typically responsible for fixing and maintaining the server (unmanaged server) or the VPS provider may supply server admin tasks for the client (managed server).
Dedicated Hosting Service
The user gets his or her own web server and gains full control over it (user has root access for Linux/administrator access for Windows); however, the user typically does not own the server. One type of dedicated hosting is self-managed or unmanaged. This is often the least expensive for dedicated plans. The customer has full admin access to the server, which means the client is responsible for the security and maintenance of their own dedicated server.
Managed Hosting Service
The client gets their own web server but they are not allowed complete control over it (the customer is denied root access for Linux/administrator access for Windows); however, they may control their data via FTP or other remote management software. The client is not given full control so that the provider can guarantee the quality of service by not allowing the client to change the server or possibly create configuration issues. The client usually does not own the server. The server is leased to the customer.
Colocation Web Hosting Service
Similar to the dedicated website hosting service, but the customer owns the colocation server; the hosting company offers physical space that the server takes up and manages the computer. This is the most powerful and expensive kind of web hosting service. In most cases, the colocation provider may provide little to no support directly for their client's server, providing just the electrical, internet access, and storage facilities for the computer. In most cases for colocation, the client would have their own administrator visit the data center on-site to do any hardware upgrades or changes. Formerly, many colocation providers would accept any computer configuration for hosting, even ones housed in desktop-style minitower cases, but most hosting organizations now demand rack mount enclosures and standard system configurations.
Cloud Hosting
This is a new kind of hosting platform that permits users powerful, scalable and reliable hosting based on clustered load-balanced servers and utility billing. A cloud-hosted site may be more reliable than others since other servers in the cloud can take over when a single piece of hardware fails. Also, local power failures or even natural disasters are less of a problem for cloud hosted sites, as cloud hosting is not centralized. Cloud hosting also allows providers to bill users just for resources consumed by the user, instead of a flat rate for the amount the client guesses they may consume, or a fixed rate upfront hardware investment. Alternatively, the decentralization may give clients less control on where their data is located, which could be a deal breaker for clients with data security or privacy worries.
Clustered Hosting
Having several servers host the same content for stable resource utilization. Clustered computers are a amazing solution for high-availability dedicated hosting, or customizing a scalable web hosting solution. A cluster may separate website serving from database hosting capability. (Usually web hosts use clustered hosting for their shared hosting plans, as there are a number of benefits to the mass managing of customers).
Grid Hosting
This type of distributed hosting is when a server cluster acts like a grid and is made of multiple nodes.
Home Server
Generally, a sole machine located in a private residence can be used to host one or a few web sites from a typically consumer-grade broadband connection. These can be purpose-built computers or more commonly old PCs. Some internet service providers purposefully attempt to block residential servers by blocking incoming requests to TCP port 80 of the customer's connection and by refusing to supply static IP addresses. A good method to attain a reliable DNS hostname is by obtaining an account with a dynamic DNS service. A dynamic DNS service will automatically update the IP address that a URL directs to when the IP address changes.
Some specific kinds of hosting provided by web host service providers:
- File hosting service: hosts files, not web pages
- Image hosting service
- Video hosting service
- Blog hosting service
- Paste bin
- Shopping cart software
- Email hosting service
Host Management
The host may also offer an interface or control panel for managing the website server and installing scripts, as well as other modules and service applications like email. A web server that doesn't use a control panel for managing the hosting account, is sometimes referred to as a "headless" server. Some hosts specialize in certain software or services (e.g. e-commerce, blogs, etc.).
Reliability and Uptime
The availability of a site is measured by the percentage of a year in which the website is publicly accessible and reachable via the internet. This differs from measuring the uptime of a system. Uptime refers to the system itself being online. Uptime does not take into account being able to reach it as in the event of a network outage. A hosting provider's Service Level Agreement (SLA) might include a reasonable amount of scheduled downtime per year in order to perform maintenance on the servers. The scheduled downtime is generally not included in the SLA timeframe and needs to be subtracted from the Total Time when availability is calculated. Depending on the wording of an SLA, if the availability of a system drops below that in the signed SLA, a hosting provider generally will provide a partial refund for lost time. How downtime is calculated is different from provider to provider, therefore understanding the SLA is not to be taken lightly. Not all providers release uptime statistics. Most hosting providers will guarantee at least 99.9% uptime which will provide for 43 minutes of downtime each month, or 8 hours and 45 minutes of downtime per year.
Obtaining Hosting
Website hosting is sometimes provided as part of a larger internet access plan from internet service providers. There are also a number of free and paid providers offering web hosting.
A client should evaluate the requirements of the application to choose what kind of hosting to use. Such considerations include database server software, scripting software, and operating system. Many hosting providers offer Linux-based web hosting which offers a wide range of different software. A typical configuration for a Linux server is the LAMP platform: Linux, Apache, MySQL, and PHP/Perl/Python. The web hosting client might want to obtain other services, such as email for their business domain, databases or multimedia services. A user might also prefer Windows as the hosting platform. The client still can choose from Perl, PHP, Python, and Ruby, but the client may also use ASP.NET or ASP Classic. Web hosting packages sometimes include a website content management system, so the end-user doesn't have to worry about the more technical items.
Security
Since website hosting services host websites belonging to their clients, web security is a very important worry. When a client agrees to use a web hosting service, they are passing on control of the security of their site to the provider that is hosting the site. The degree of security that a website hosting service provides is very important to a possible customer and can be a major component when deciding which provider a client will choose.
Web hosting server can be targeted by malicious users in various ways, including uploading malware or malicious code onto a hosted site. These attacks {may|might| be done for various reasons, such as stealing credit card info, launching a Distributed Denial of Service Attack (DDoS) or spamming.
