Hoa Website Hosting Companies
A website hosting service is a kind of internet hosting service that permits people and organizations to make their website available via the world wide web. Web hosts are organizations that provide space on a server owned or leased for use by clients, as well as providing internet connectivity, usually in a data center. Website hosts can also provide 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
Up till 1991, the internet was restricted 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 tiny number of web pages. The world wide web protocols had only just been written and not till the end of 1993 would there be a graphical web browser for Mac or Windows computers. Even after there was some opening up of internet access, the situation was convoluted until 1995.
To host a web site on the internet, a person or organization would need their own computer or server. As not all companies had the budget or capability to complete this, web site hosting services started to offer to host users' websites on their own servers, without the client needing to install the necessary infrastructure required to run the website. The owners of the sites, also called webmasters, would be able to construct a website that would be hosted on the web hosting service's server and published to the internet by the web hosting service.
As the number of users on the internet increased, the pressure for companies, both large and tiny, to have an online presence grew. By 1995, companies such as GeoCities, Angelfire and Tripod were supplying free hosting.
Classification
Smaller Hosting Services
The most basic is awebsite page and small-scale file hosting, where files can be uploaded via File Transfer Protocol (FTP) or a web site interface. The files are often delivered to the web "as is" or with very little processing. Quite a few internet service providers (ISPs) offer this service at no charge to users. Individuals and companies may also acquire web page hosting from other service providers.
Free website hosting service is supplied by different companies with limited services, generally 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 at times has a greater investment depending upon the size and type of the site.
Larger Hosting Services
Many big companies that are not ISPs need to be constantly connected to the web to send email, files, etc. to other sites. The organization may use the computer as a website host to supply details of their products and services and facilities for internet-based orders.
A complex site requires a more expanded package that provides 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 develop 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 more secure.
Types of Hosting
Internet hosting services can run web servers. The scope of web hosting services varies a lot.
Shared Website Hosting Service
One's site is found on the same server as many other websites, ranging from a few websites to hundreds of websites. Generally, all domains may share a common pool of server resources, such as RAM and the CPU. The features that are available with this type of service can be quite basic and not flexible in terms of software and updates. Resellers sometimes provide shared website hosting and website organizations often have reseller accounts to offer hosting for clients.
Reseller Web Hosting
Reseller web hosting allows clients to take on the role of website hosts themselves. Resellers may function, for individual domains, under any combination of these following types of hosting, depending on who they are working with as a reseller. Resellers' accounts may vary tremendously in size: they may have their own virtual dedicated server to a colocated server. Many resellers provide a nearly identical service to their provider's shared hosting plan and offer the technical support themselves.
Virtual Dedicated Server
Also known as a Virtual Private Server (VPS), it divides server resources into virtual servers, where resources can be handed out in a way that doesn't directly reflect the underlying hardware. VPS will sometimes be allocated resources based on a one server to many VPSs relationship, however, virtualization may be chosen for different reasons, which includes the possibility to relocate a VPS container between servers. Users might have root access to their own virtual space. Clients are sometimes responsible for patching and maintaining the server (unmanaged server) or the VPS provider may provide server administration jobs for the customer (managed server).
Dedicated Hosting Service
The user gets their own web server and gains full control over it (user has root access for Linux/administrator access for Windows); however, the client generally doesn't own the server. One kind of dedicated hosting is self-managed or unmanaged. This is sometimes the least expensive for dedicated plans. The customer has full admin access to the server, which means the user is responsible for the security and maintenance of their own dedicated server.
Managed Hosting Service
The user gets his or her own website server but is not allowed full control over it (the user is not given root access for Linux/administrator access for Windows); however, they may manage their data via FTP or other remote management tools. The user is not permitted full control so that the provider can guarantee the quality of service by not granting the customer to modify the server or possibly create configuration issues. The user often doesn't own the server. The server is leased to the customer.
Colocation Web Hosting Service
Similar to the dedicated web hosting service, but the user owns the colocation server; the hosting company offers physical space that the computer takes up and takes care of the computer. This is the most powerful and costly kind of website hosting service. In most cases, the colocation provider may supply little to no support directly for their user's computer, providing only the electrical, internet access, and storage facilities for the server. In most cases for colocation, the user would have his own administrator visit the data center on-site to do any hardware upgrades or changes. Formerly, a number of colocation providers would allow any server 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 modern type of hosting platform that permits customers strong, scalable and reliable hosting based on clustered load-balanced servers and utility billing. A cloud-hosted site might be more reliable than others as other servers in the cloud can compensate when an individual piece of hardware stops working. Furthermore, local power disruptions or even natural disasters are less problematic for cloud hosted websites, as cloud hosting is not centralized. Cloud hosting also permits providers to charge users just for resources consumed by the customer, instead of a flat rate for the amount the user thinks they will use, or a fixed rate upfront hardware investment. Alternatively, the lack of centralization might give clients less control on where their information is located, which could be a deal breaker for clients with data security or privacy concerns.
Clustered Hosting
Having a bunch of servers host the same content for stable resource utilization. Clustered servers are a great solution for high-availability dedicated hosting, or customizing a scalable website hosting system. A cluster may separate website serving from database hosting capability. (Usually website hosts use clustered hosting for their shared hosting plans, as there are many benefits to the mass managing of clients).
Grid Hosting
This form of distributed hosting is when a server cluster acts like a grid and is composed of multiple nodes.
Home Server
Usually, an individual machine situated in a private residence can be used to host one or multiple websites from a typically consumer-grade broadband connection. These can be purpose-built machines or more commonly old PCs. Some internet service providers purposefully work to block residential servers by stopping incoming requests to TCP port 80 of the customer's connection and by refusing to supply static IP addresses. A wonderful method to have a reliable DNS hostname is by creating an account with a dynamic DNS service. A dynamic DNS service will automatically update the IP address that a URL points to when the IP address changes.
Some specific types of hosting provided by website 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 might also supply an interface or control panel for managing the web server and installing scripts, as well as other modules and service applications like email. A website server that does not use a control panel for managing the hosting account, is generally 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 website is measured by the percentage of a year in which the site is publicly accessible and reachable via the internet. This is different 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 when there is a network outage. A hosting provider's Service Level Agreement (SLA) may include a reasonable amount of scheduled downtime per year in order to perform maintenance on the computers. This scheduled downtime is sometimes excluded from 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 at times will provide a partial refund for time lost. How downtime is determined changes from provider to provider, therefore reading the SLA is not to be taken lightly. Not all providers publicly display uptime information. Most hosting providers will guarantee at least 99.9% uptime which will allow for 43 minutes of downtime per month, or 8 hours and 45 minutes of downtime per year.
Obtaining Hosting
Web hosting is generally offered as part of a complete internet access plan from internet service providers. There are also a lot of free and paid providers offering web hosting.
A customer must 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. A number of hosting providers offer Linux-based website 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 user may want to acquire other services, such as email for their business domain, databases or multimedia services. A customer might also prefer Windows as the hosting platform. The user still can choose from Perl, PHP, Python, and Ruby, but the client may also use ASP.NET or ASP Classic. Web hosting packages generally include a web content management system, so the end-user doesn't have to be bothered about the more technical items.
Security
Since website hosting services host sites belonging to their customers, web security is a vital worry. When a client agrees to use a web hosting service, they are giving up control of the security of their site to the company that is hosting the website. The level of security that a web hosting service supplies is very important to a possible client and can be a major point when deciding which provider a client should choose.
Website hosting computers can be targeted by malicious people in various ways, including uploading malware or malicious code onto a hosted site. These attacks {may|might| be done for different reasons, including stealing credit card data, launching a Distributed Denial of Service Attack (DDoS) or spamming.
