Best Website Hosting Company In India
A website hosting service is a type of internet hosting service that permits people and companies to make their website available via the world wide web. Website hosts are companies that offer space on a server owned or leased for use by users, as well as providing internet connectivity, usually in a data center. Web 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
Until 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 website pages. The world wide web protocols had only just been created and not until the end of 1993 would there be a graphical web site browser for Mac or Windows computers. Even after there was additional internet access, the situation was challenging until 1995.
To host a web site on the internet, a person or business would need their own computer or server. As not all companies had the budget or expertise to achieve this, web hosting services began to provide services to host users' sites on their own servers, without the client needing to own the necessary infrastructure neededd to run the website. The owners of the websites, also known as webmasters, would be able to create a website that would be hosted on the website hosting service's server and published to the internet by the website hosting service.
As the number of users on the internet grew, the demand for companies, both large and small, to have an online presence grew. By 1995, organizations such as GeoCities, Angelfire and Tripod were supplying 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 often delivered to the web "as is" or with very little processing. Many internet service providers (ISPs) offer this service at no charge to subscribers. Individuals and companies may also acquire web page hosting from alternative service providers.
Free website hosting service is provided by different organizations with limited services, sometimes supported by adds, and sometimes limited when compared to paid hosting.
Single page hosting is often sufficient for personal website pages. Personal web site hosting is typically free, advertisement-sponsored, or inexpensive. Business web site hosting sometimes has a higher expense depending upon the size and type of the site.
Larger Hosting Services
Many large organizations that are not ISPs need to be constantly 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 supply details of their products and services and facilities for website orders.
A complex site demands 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 facilities allow clients to create 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 more secure.
Types of Hosting
Internet hosting services can run web servers. The scope of web hosting services differs a lot.
Shared Website Hosting Service
One's website is found on the same server as many other sites, 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 relatively simple and not flexible in terms of software and updates. Resellers generally make available shared web hosting and website organizations generally have reseller accounts to provide hosting for clients.
Reseller Website Hosting
Reseller website hosting permits clients to be website hosts themselves. Resellers can 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 vary a lot 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 tech 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 does not directly reflect the computer's hardware. VPS will at times be allocated resources based on a one server to many VPSs relationship, however, virtualization may be wanted for varying reasons, which includes the ability to relocate a VPS container from one server to another. Users might have root access to their own virtual space. Clients are usually responsible for patching and maintaining the server (unmanaged server) or the VPS provider may supply server admin tasks for the customer (managed server).
Dedicated Hosting Service
The customer gets his or her own web server and has absolute 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 often the least expensive for dedicated plans. The client has full admin access to the server, which means the customer is responsible for the security and maintenance of their own dedicated server.
Managed Hosting Service
The client gets their own web server but is not allowed full control over the server (the client is denied root access for Linux/administrator access for Windows); but, they can manage their data via FTP or other remote management tools. The client is not allowed full control so that the provider can guarantee the quality of service by not permitting the user to modify the server or potentially create configuration problems. The user typically 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 customer owns the colocation server; the hosting company provides physical space that the server takes up and manages 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 machine, 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 kind of hosting platform that allows users strong, scalable and reliable hosting based on clustered load-balanced servers and utility billing. A cloud-hosted website might be more reliable than alternatives since other computers in the cloud can take over when an individual piece of hardware fails. Also, 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 invoice users only for resources used by the client, rather than a flat fee for the amount the user thinks they may use, or a fixed amount upfront hardware investment. Alternatively, the lack of centralization might give clients less control over where their information is located, which could be an issue for clients with data security or privacy issues.
Clustered Hosting
Having a bunch of servers hosting the same content for stable resource utilization. Clustered computers are a fantastic solution for high-availability dedicated hosting, or customizing a scalable web hosting system. A cluster may separate web serving from database hosting capability. (Often website hosts use clustered hosting for their shared hosting plans, as there are quite a few pros 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
Generally, an individual machine placed in a private residence can be used to host one or a few websites from a typically consumer-grade broadband connection. These can be purpose-built computers or more commonly older PCs. Some internet service providers actively attempt to block residential servers by blocking incoming requests to TCP port 80 of the user's connection and by refusing to offer static IP addresses. A easy opportunity to have a reliable DNS hostname is by having an account with a dynamic DNS service. A dynamic DNS service will automatically change 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 can 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 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 available 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 certain amount of scheduled downtime each year in order to perform maintenance on the systems. The scheduled downtime is at times 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 sometimes will supply a partial refund for lost time. How downtime is determined is different from provider to provider, therefore understanding the SLA is imperative. Not all providers show uptime stats. A number of hosting providers will guarantee at least 99.9% uptime which will allow for 43 minutes of downtime every month, or 8 hours and 45 minutes of downtime each year.
Obtaining Hosting
Website hosting is sometimes provided as part of a larger internet access plan from ISPs. There are also a lot of free and paid providers offering web hosting.
A client needs to 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 provide 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 website hosting customer 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. Website hosting packages sometimes include a website content management system, so the end-user doesn't have to be concerned about the more technical items.
Security
Since web hosting services host sites belonging to their clients, internet security is a vital concern. When a client agrees to use a web hosting service, they are passing on control of the security of their site to the organization that is hosting the site. The amount of security that a website hosting service offers is super important to a possible client and can be a major point when deciding which provider a client should choose.
Web hosting computers can be targeted by malicious people in different 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 information, launching a Distributed Denial of Service Attack (DDoS) or spamming.
