Ecommerce Website Hosting India
A website hosting service is a kind of internet hosting service that permits individuals and companies to make their website accessible via the world wide web. Website hosts are companies that offer 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 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 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 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 web site on the internet, a person or company would need their own computer system or server. As not all organizations had the budget or capability to achieve this, web site hosting services started to offer to host users' sites on their own servers, without the customer needing to put together the necessary infrastructure required to operate the web site. The owners of the websites, 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 internet 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, organizations 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 generally delivered to the web "as is" or with minimal processing. Many internet service providers (ISPs) offer this service free to subscribers. Individuals and companies may also obtain web page hosting from alternative 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 generally sufficient for personal web pages. Personal web site hosting is typically free, advertisement-sponsored, or inexpensive. Business web site hosting at times has a higher expense depending upon the size and type of the site.
Larger Hosting Services
Many large 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 website orders.
A complex site 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 programs allow customers 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 web hosting services differs a lot.
Shared Web Hosting Service
One's site is located on the same server as many other websites, ranging from a few websites to hundreds of websites. Usually, 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 quite simple and not flexible in terms of software and updates. Resellers at times sell shared web hosting and web organizations often have reseller accounts to offer hosting for clients.
Reseller Website Hosting
Reseller website hosting allows clients to take on the role of web hosts themselves. Resellers could 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 differentiate 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 supply 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 allocated in a way that doesn't directly reflect the computer's hardware. VPS will generally be allocated resources based on a one server to many VPSs relationship, however, virtualization may be desired for a number of reasons, including the ability to move a VPS container between servers. Users might have root access to their own virtual space. Customers are sometimes responsible for fixing and maintaining the server (unmanaged server) or the VPS provider may provide server admin tasks for the client (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); but, the client typically does not own the server. One type 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 customer is responsible for the security and maintenance of their own dedicated server.
Managed Hosting Service
The user gets their own web 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 customer is not granted full control so that the provider can guarantee the quality of service by not giving the client to change the server or potentially create configuration issues. The client typically does not own the server. The server is leased to the user.
Colocation Web Hosting Service
Similar to the dedicated web hosting service, but the client owns the colocation server; the hosting company provides physical space that the server takes up and manages the computer. This is the strongest and expensive kind of website hosting service. In most cases, the colocation provider may offer little to no help directly for their customer's server, providing just the electrical, internet access, and storage facilities for the computer. In most cases for colocation, the user would have his own administrator go to the data center on-site to do any hardware upgrades or changes. Formerly, many colocation providers would accept any computer 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 modern kind of hosting platform that permits users strong, scalable and reliable hosting based on clustered load-balanced servers and utility billing. A cloud-hosted site may be more reliable than others since other servers in the cloud can compensate 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 not centralized. Cloud hosting also permits providers to bill users just for resources used by the user, rather than a flat fee for the amount the client assumes they may consume, or a fixed cost upfront hardware investment. Alternatively, the lack of centralization may give customers less control on where their information is located, which could be a deal breaker for users with data security or privacy worries.
Clustered Hosting
Having a bunch of servers hosting the same content for better resource utilization. Clustered computers are a great solution for high-availability dedicated hosting, or creating a scalable web hosting solution. A cluster may separate web serving from database hosting capability. (Often 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 acts like a grid and is made of multiple nodes.
Home Server
Sometimes, a single machine situated in a private residence can be used to host one or multiple websites from a generally consumer-grade broadband connection. These can be purpose-built machines or more commonly old PCs. Some ISPs actively attempt to block home servers by stopping incoming requests to TCP port 80 of the customer's connection and by refusing to provide static IP addresses. A common opportunity to get 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 directs to when the IP address changes.
Some specific kinds of hosting supplied 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 offer 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 often 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 during 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 servers. This scheduled downtime is generally 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 computer drops lower than that in the signed SLA, a hosting provider generally will offer a partial refund for time lost. How downtime is calculated varies from provider to provider, therefore reading the SLA is important. 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 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 is encouraged 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 various software. A typical configuration for a Linux server is the LAMP platform: Linux, Apache, MySQL, and PHP/Perl/Python. The website hosting user might want to obtain other services, such as email for their business domain, databases or multimedia services. A user may 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 concerned about the more technical items.
Security
Since web hosting services host sites which belong to their clients, online security is an important worry. When a client agrees to use a web hosting service, they are passing on control of the security of their website to the company that is hosting the site. The level of security that a web hosting service offers is super important to a potential client and can be a major point when considering which supplier a client will choose.
Website hosting server 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, such as stealing credit card data, launching a Distributed Denial of Service Attack (DDoS) or spamming.
