Website Hosting Paypal
Website Hosting Paypal
A web hosting service is a type of internet hosting service that allows individuals and organizations to make their site available via the world wide web. Web hosts are organizations that supply space on a server owned or leased for use by customers, as well as providing internet connectivity, typically 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 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 tiny number of website pages. The world wide web protocols had only just been written and not until the end of 1993 would there be a graphical website browser for Mac or Windows computers. Even after there was some opening up of internet availability, the situation was confused until 1995.
To host a website on the internet, a person or organization would need their own computer or server. As not all organizations had the money or experience to complete this, web site hosting services began to provide services to host users' sites on their own servers, without the customer needing to install the necessary infrastructure neededd to operate the web site. The owners of the sites, also called webmasters, would be able to develop a website that would be hosted on the website hosting service's server and published to the web by the web hosting service.
As the number of users on the world wide web increased, the pressure for companies, both big and tiny, to have an online presence increased. By 1995, organizations such as GeoCities, Angelfire and Tripod were supplying free hosting.
Classification
Smaller Hosting Services
The simplest is aweb page and small-scale file hosting, where files can be uploaded via File Transfer Protocol (FTP) or a web interface. The files are usually delivered to the web "as is" or with minimal processing. A lot of internet service providers (ISPs) provide this service with no cost to subscribers. Individuals and companies may also obtain web page hosting from other service providers.
Free website hosting service is provided by different companies with limited services, generally supported by advertisements, and generally 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 often has a higher expense depending upon the size and type of the site.
Larger Hosting Services
Many big companies that are not internet service providers need to be permanently connected to the web so they can send email, files, etc. to other sites. The organization may use the computer as a website host to provide details of their products and services and facilities for website orders.
A complicated website requires a more comprehensive package that offers database support and application development platforms (e.g. ASP.NET, ColdFusion, Java EE, Perl/Plack, PHP or Ruby on Rails). These facilities allow clients to write or install scripts for applications like forums and content management. Also, Secure Sockets Layer (SSL) is typically used for websites that wish to keep the data transmitted safe.
Types of Hosting
Internet hosting services can run web servers. The scope of website hosting services varies a lot.
Shared Website Hosting Service
One's website is placed on the same server as many other websites, ranging from a few sites to hundreds of websites. Generally, all domains may share a common pool of server resources, such as RAM and the CPU. The features available with this kind of service can be relatively simple and not flexible in terms of software and updates. Resellers generally sell shared website hosting and website organizations sometimes have reseller accounts to supply hosting for clients.
Reseller Web Hosting
Reseller web hosting allows customers to take on the role of web hosts themselves. Resellers can function, for individual domains, under any combination of these listed types of hosting, depending on who they are working with as a reseller. Resellers' accounts may vary quite a bit in size: they may have their own virtual dedicated server to a colocated server. Many resellers offer a nearly identical service to their provider's shared hosting plan and offer the tech support themselves.
Virtual Dedicated Server
This is also known as a Virtual Private Server (VPS), it divides server resources into virtual servers, where resources can be allocated in a way that doesn't directly reflect the underlying hardware. VPS will generally be allocated resources based on a one server to many VPSs relationship, however, virtualization might be desired for varying reasons, including the ability to relocate a VPS container between servers. The users may have root access to their own virtual space. Users are often responsible for patching and maintaining the server (unmanaged server) or the VPS provider may offer server admin jobs 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 customer usually 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 client has full administrative access to the server, which means the client is responsible for the security and maintenance of their own dedicated server.
Managed Hosting Service
The customer gets their own website server but they are not allowed complete control over it (the customer is denied root access for Linux/administrator access for Windows); however, they can control their data via FTP or other remote management tools. The client is not given complete control so that the provider can guarantee the quality of service by not permitting the client to modify the server or possibly create configuration issues. The customer often doesn't own the server. The server is leased to the client.
Colocation Website Hosting Service
Almost the same as the dedicated website hosting service, but the user owns the colocation server; the hosting company supplies 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 assistance 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 go to the data center on-site to do any hardware upgrades or changes. Formerly, a lot of colocation providers would allow 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 relatively modern type of hosting platform that allows users powerful, scalable and reliable hosting based on clustered load-balanced servers and utility billing. A cloud-hosted site might be more reliable than alternatives as other computers in the cloud can take over when a single piece of hardware fails. Furthermore, local power failures or even natural disasters are less of a problem for cloud hosted sites, as cloud hosting is decentralized. Cloud hosting also permits providers to charge users only for resources consumed by the client, instead of a flat rate for the amount the client expects they may use, or a fixed amount upfront hardware investment. Alternatively, the decentralization may provide clients less control over where their information is located, which could be an issue for users with data security or privacy concerns.
Clustered Hosting
Having several servers hosting the same content for better resource utilization. Clustered computers are a sturdy solution for high-availability dedicated hosting, or building a scalable web hosting solution. A cluster may separate web serving from database hosting capability. (Typically website hosts use clustered hosting for their shared hosting plans, as there are a number of pros to the mass managing of clients).
Grid Hosting
This type of distributed hosting is when a server cluster performs like a grid and is composed of multiple nodes.
Home Server
Usually, an individual computer situated in a private residence can be used to host one or more websites from a typically consumer-grade broadband connection. These can be purpose-built computers or more commonly older PCs. Some internet service providers actively try to block residential servers by disallowing incoming requests to TCP port 80 of the client's connection and by refusing to provide static IP addresses. A wonderful way 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 directs to when the IP address changes.
Some specific kinds of hosting supplied 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 can 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 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 when there is a network outage. A hosting provider's Service Level Agreement (SLA) may include a specific amount of scheduled downtime each year in order to perform maintenance on the systems. This scheduled downtime is often 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 lower than that in the signed SLA, a hosting provider generally will provide a partial refund for time lost. How downtime is calculated changes from provider to provider, therefore examining the SLA is not to be taken lightly. Not all providers produce uptime stats. 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 each year.
Obtaining Hosting
Website hosting is at times supplied as part of a complete internet access plan from internet service providers. There are also a lot of free and paid providers offering website hosting.
A customer is encouraged to evaluate the requirements of the application to choose what type of hosting to use. Such considerations include database server software, scripting software, and operating system. a lot of hosting providers offer Linux-based web hosting which provides a wide range of various software. A typical configuration for a Linux server is the LAMP platform: Linux, Apache, MySQL, and PHP/Perl/Python. The website hosting client might want to have other services, such as email for their business domain, databases or multimedia services. A user may also choose Windows as the hosting platform. The customer still can choose from Perl, PHP, Python, and Ruby, but the user may also use ASP.NET or ASP Classic. Website hosting packages generally include a web content management system, so the end-user does not have to worry about the more technical parts.
Security
Because web hosting services host websites belonging to their customers, online security is an extreme item. When a client agrees to use a web hosting service, they are relinquishing control of the security of their site to the service provider that is hosting the website. The degree of security that a web hosting service supplies is super important to a prospective client and can be a major issue when deciding which supplier a client will choose.
Website hosting server can be targeted by malicious users in various ways, including uploading malware or malicious code onto a hosted website. These attacks {may|might| be done for different reasons, such as stealing credit card data, launching a Distributed Denial of Service Attack (DDoS) or spamming.
