Website Hosting In Delhi
A web hosting service is a type of internet hosting service that allows individuals and companies to make their site accessible via the world wide web. Website hosts are organizations that offer space on a server owned or leased for use by customers, as well as providing internet connectivity, usually in a data center. Website hosts can also supply 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 small number of web 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 greater internet availability, the situation was complicated 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 expertise to do this, web site hosting services began to offer to host users' sites on their own servers, without the client needing to own the necessary infrastructure neededd to operate the web site. The owners of the websites, also called 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 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 offering free hosting.
Classification
Smaller Hosting Services
The simplest 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 generally delivered to the web "as is" or with almost no processing. Quite a few internet service providers (ISPs) provide this service with no cost to users. People and organizations may also acquire web page hosting from alternative service providers.
Free web hosting service is provided by different companies with limited services, at times supported by adds, and at times limited when compared to paid hosting.
Single page hosting is generally sufficient for personal website pages. Personal web site hosting is typically free, advertisement-sponsored, or inexpensive. Business web site hosting sometimes has a greater investment 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 in order to send email, files, etc. to other sites. The company may use the computer as a website host to supply details of their products and services and facilities for online 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 options allow clients to develop 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 manage web servers. The scope of website hosting services differs a lot.
Shared Website Hosting Service
One's website is located on the same server as many other websites, ranging from a few sites to hundreds of sites. 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 fairly basic and not flexible in terms of software and updates. Resellers sometimes provide shared web hosting and web organizations generally have reseller accounts to provide hosting for customers.
Reseller Web Hosting
Reseller website hosting allows customers to be website hosts themselves. Resellers can 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 quite a bit in size: they may have their own virtual dedicated server to a colocated server. Many resellers supply a similar service to their provider's shared hosting plan and offer the tech support themselves.
Virtual Dedicated Server
Also known as a Virtual Private Server (VPS), it separates server resources into virtual servers, where resources can be split up in a way that does not directly reflect the underlying hardware. VPS will sometimes be allocated resources based on a one server to many VPSs relationship, but, virtualization might be chosen for a number of reasons, which includes the option to move a VPS container between servers. Users may have root access to their own virtual space. Customers are often responsible for fixing and maintaining the server (unmanaged server) or the VPS provider may supply server administration jobs for the customer (managed server).
Dedicated Hosting Service
The client gets his or her own web server and has complete control over it (user has root access for Linux/administrator access for Windows); but, the client usually doesn't own the server. One kind of dedicated hosting is self-managed or unmanaged. This is usually the least expensive for dedicated plans. The customer has full administrative access to the server, which means the user is responsible for the security and maintenance of their own dedicated server.
Managed Hosting Service
The customer gets his or her own web server but they are not allowed complete control over the server (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 customer is not given full control so that the provider can guarantee the quality of service by not permitting the user to change the server or perhaps create configuration issues. The client sometimes does not own the server. The server is leased to the user.
Colocation Website Hosting Service
Almost the same as the dedicated website hosting service, but the client owns the colocation server; the hosting organization offers physical space that the server takes up and manages the server. This is the strongest and costly kind of web hosting service. In most cases, the colocation provider may offer little to no assistance directly for their user's machine, providing just the electrical, internet access, and storage facilities for the computer. In most cases for colocation, the customer would have his own administrator visit the data center on-site to do any hardware upgrades or changes. Formerly, a lot of colocation providers would accept any server configuration for hosting, even ones housed in desktop-style minitower cases, but most hosting organizations now insist on rack mount enclosures and standard system configurations.
Cloud Hosting
This is a relatively modern kind of hosting platform that allows clients strong, scalable and reliable hosting based on clustered load-balanced servers and utility billing. A cloud-hosted website might be more stable than others since other computers in the cloud can compensate when a single piece of hardware breaks. Furthermore, local power outages or even natural disasters are less of a problem for cloud hosted websites, as cloud hosting is decentralized. Cloud hosting also allows providers to charge users only for resources consumed by the customer, instead of a flat rate for the amount the user expects they will consume, or a fixed rate upfront hardware investment. Alternatively, the lack of centralization might provide users less control on where their information is located, which could be an issue for clients with data security or privacy concerns.
Clustered Hosting
Having multiple servers host the same content for improved resource utilization. Clustered servers 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. (Often web hosts use clustered hosting for their shared hosting plans, as there are quite a few benefits to the mass managing of clients).
Grid Hosting
This variation of distributed hosting is when a server cluster performs like a grid and is composed of multiple nodes.
Home Server
Typically, a sole server located in a private home can be used to host one or a few sites from a usually 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 not allowing incoming requests to TCP port 80 of the customer's connection and by refusing to offer static IP addresses. A wonderful method to keep 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 points to when the IP address changes.
Some specific kinds of hosting supplied by website host service providers:
- File hosting service: hosts files, not website pages
- Image hosting service
- Video hosting service
- Blog hosting service
- Paste bin
- Shopping cart software
- Email hosting service
Host Management
The host could also provide an interface or control panel for managing the web 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 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 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 during network outage. A hosting provider's Service Level Agreement (SLA) may include a certain amount of scheduled downtime per year in order to perform maintenance on the servers. The scheduled downtime is sometimes 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 sometimes will supply a partial refund for time lost. How downtime is calculated changes from provider to provider, therefore reading the SLA is crucial. Not all providers show uptime statistics. A number of 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 sometimes offered as part of a larger internet access plan from ISPs. There are also a lot of free and paid providers offering website hosting.
A customer 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 provides 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 might want to have other services, such as email for their organization domain, databases or multimedia services. A client might also choose Windows as the hosting platform. The user still can choose from Perl, PHP, Python, and Ruby, but the user may also use ASP.NET or ASP Classic. Website hosting packages often include a web content management system, so the end-user doesn't have to be concerned about the more technical components.
Security
Since website hosting services host websites which belong to their customers, internet security is a vital item. When a customer agrees to use a website hosting service, they are passing on control of the security of their website to the service provider that is hosting the site. The degree of security that a web hosting service provides is super important to a potential customer and can be a major subject when deciding which supplier a client may choose.
Web hosting server can be attacked by malicious users in various ways, which include uploading malware or malicious code onto a hosted website. These attacks {may|might| be done for different reasons, such as stealing credit card information, launching a Distributed Denial of Service Attack (DDoS) or spamming.
