Best Website Hosting India
A website hosting service is a kind of internet hosting service that permits individuals and companies to make their site available via the world wide web. Web hosts are organizations that provide space on a server owned or leased for use by users, as well as providing internet connectivity, typically 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 tiny number of web pages. The world wide web protocols had only just been established and not till the end of 1993 would there be a graphical web site browser for Mac or Windows computers. Even after there was some opening up of internet availability, the situation was challenging until 1995.
To host a website on the internet, a person or business would need their own computer or server. As not all companies had the budget or capability to do this, web hosting services began to supply services to host users' websites on their own servers, without the customer needing to install the necessary infrastructure neededd to run the website. The owners of the websites, also known as webmasters, would be able to build a website 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 internet increased, the pressure for companies, both big and small, to have an online presence increased. By 1995, companies such as GeoCities, Angelfire and Tripod were supplying free hosting.
Classification
Smaller Hosting Services
The most simple is awebsite page and small-scale file hosting, where files can be uploaded via File Transfer Protocol (FTP) or a web interface. The files are sometimes delivered to the web "as is" or with minimal processing. Many internet service providers (ISPs) provide this service at no charge to users. People and organizations may also obtain website page hosting from alternative service providers.
Free web hosting service is offered by various organizations with limited services, sometimes supported by adds, and generally limited when compared to paid hosting.
Single page hosting is often 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 large 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 company may use the computer as a website host to supply details of their goods and services and facilities for website orders.
A complex website requires a more comprehensive 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 customers 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 safe.
Types of Hosting
Internet hosting services can manage web servers. The scope of web hosting services varies a lot.
Shared Website Hosting Service
One's site is located on the same server as many other websites, ranging from a few websites 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 kind of service can be relatively simple and not flexible in terms of software and updates. Resellers often provide shared website hosting and web companies generally have reseller accounts to supply hosting for clients.
Reseller Website Hosting
Reseller website hosting permits 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 working with as a reseller. Resellers' accounts may differentiate a fair amount 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 supply 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 handed out 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, but, virtualization may be done for a number of reasons, including the ability to move a VPS container from one server to another. Users may have root access to their own virtual space. Customers are generally responsible for fixing and maintaining the server (unmanaged server) or the VPS provider may offer server admin tasks for the client (managed server).
Dedicated Hosting Service
The client gets their own web server and gets complete control over it (user has root access for Linux/administrator access for Windows); however, the customer generally does not own the server. One kind of dedicated hosting is self-managed or unmanaged. This is generally the least expensive for dedicated plans. The client 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 customer gets his or her own website server but they are not allowed full 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 software. The user is not permitted full control so that the provider can guarantee the quality of service by not permitting the customer to change the server or perhaps create configuration issues. The customer generally does not own the server. The server is leased to the user.
Colocation Website Hosting Service
Similar to the dedicated website hosting service, but the client owns the colocation server; the hosting company provides physical space that the server takes up and takes care of the server. This is the most powerful and costly type of website hosting service. In most cases, the colocation provider may provide little to no help directly for their client's computer, providing just the electrical, internet access, and storage facilities for the server. In most cases for colocation, the client 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 accept any system configuration for hosting, even ones housed in desktop-style minitower cases, but most hosting organizations now require rack mount enclosures and standard system configurations.
Cloud Hosting
This is a relatively modern type of hosting platform that allows users strong, scalable and reliable hosting based on clustered load-balanced servers and utility billing. A cloud-hosted site may be more stable than others since other computers in the cloud can compensate when an individual piece of hardware fails. Furthermore, local power failures or even natural disasters are less problematic for cloud hosted sites, as cloud hosting is decentralized. Cloud hosting also allows providers to charge users just for resources used by the customer, rather than a flat rate for the amount the customer guesses they might consume, or a fixed amount upfront hardware investment. Alternatively, the lack of centralization may give clients less control over where their information is located, which could be a problem for customers with data security or privacy issues.
Clustered Hosting
Having multiple servers host the same content for improved resource utilization. Clustered computers are a wonderful solution for high-availability dedicated hosting, or customizing a scalable web hosting solution. A cluster may separate web serving from database hosting capability. (Sometimes web hosts use clustered hosting for their shared hosting plans, as there are many options to the mass managing of customers).
Grid Hosting
This type of distributed hosting is when a server cluster acts like a grid and is composed of multiple nodes.
Home Server
Often, a sole computer situated in a private home can be used to host one or multiple websites from a usually consumer-grade broadband connection. These can be purpose-built machines or more commonly older PCs. Some ISPs purposefully attempt to block home servers by disallowing incoming requests to TCP port 80 of the client's connection and by refusing to provide static IP addresses. A easy way to keep a reliable DNS hostname is by creating an account with a dynamic DNS service. A dynamic DNS service will automatically change the IP address that a URL directs to when the IP address changes.
Some specific types of hosting offered 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 might also supply 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 does not use a control panel for managing the hosting account, is at times 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 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 such as during network outage. A hosting provider's Service Level Agreement (SLA) might include a reasonable amount of scheduled downtime each year in order to perform maintenance on the computers. 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 below that in the signed SLA, a hosting provider often will offer a partial refund for lost time. How downtime is calculated is different from provider to provider, therefore reading the SLA is imperative. Not all providers publicly display uptime stats. Quite a few 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 every year.
Obtaining Hosting
Website hosting is often offered as part of a general internet access plan from ISPs. There are also a lot of free and paid providers offering web hosting.
A client should 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. Many hosting providers offer Linux-based web hosting which provides a wide range of different software. A usual configuration for a Linux server is the LAMP platform: Linux, Apache, MySQL, and PHP/Perl/Python. The web hosting client may want to acquire other services, such as email for their business domain, databases or multimedia services. A client may also choose Windows as the hosting platform. The client still can choose from Perl, PHP, Python, and Ruby, but the customer may also use ASP.NET or ASP Classic. Website hosting packages at times include a website content management system, so the end-user does not have to be concerned about the more technical aspects.
Security
Since web hosting services host websites which belong to their customers, web security is a vital worry. When a client agrees to use a website hosting service, they are relinquishing control of the security of their website to the company that is hosting the website. The amount of security that a website hosting service offers is extremely important to a prospective customer and can be a major point when deciding which provider a customer should choose.
Website hosting computers can be attacked by malicious organizations in different ways, which include uploading malware or malicious code onto a hosted site. These attacks {may|might| be done for various reasons, including stealing credit card data, launching a Distributed Denial of Service Attack (DDoS) or spamming.
