Website Hosting In Mumbai
A website hosting service is a kind of internet hosting service that allows people and organizations to make their site available via the world wide web. Web hosts are companies that supply space on a server owned or leased for use by clients, as well as providing internet connectivity, typically 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
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 web pages. The world wide web protocols had only just been put together and not till the end of 1993 would there be a graphical web site browser for Mac or Windows computers. Even after there was additional internet availability, the situation was complicated until 1995.
To host a website on the internet, an individual or business would need their own computer or server. As not all companies had the money or capability to complete this, website hosting services began to provide services to host users' sites on their own servers, without the client needing to install the necessary infrastructure neededd to run the web site. The owners of the websites, also known as webmasters, would be able to build 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, companies such as GeoCities, Angelfire and Tripod were offering free hosting.
Classification
Smaller Hosting Services
The most basic is aweb page and small-scale file hosting, where files can be uploaded via File Transfer Protocol (FTP) or a web site interface. The files are sometimes delivered to the web "as is" or with very little processing. Many internet service providers (ISPs) supply this service at no charge to subscribers. Individuals and companies may also obtain website page hosting from alternative service providers.
Free web hosting service is provided by different companies with limited services, often supported by adds, and generally limited when compared to paid hosting.
Single page hosting is sometimes sufficient for personal website pages. Personal web site hosting is typically free, advertisement-sponsored, or inexpensive. Business web site hosting sometimes has a higher cost depending upon the size and type of the site.
Larger Hosting Services
Many large organizations 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 offer details of their products and services and facilities for internet-based orders.
A complicated website calls for a more comprehensive package that supplies database support and application development platforms (e.g. ASP.NET, ColdFusion, Java EE, Perl/Plack, PHP or Ruby on Rails). These facilities allow customers 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 greatly.
Shared Website Hosting Service
One's site is placed on the same server as many other websites, ranging from a few sites to hundreds of websites. Usually, all domains may share a common pool of server resources, such as RAM and the CPU. The features available with this type of service can be fairly basic and not flexible in terms of software and updates. Resellers sometimes make available shared website hosting and website organizations at times have reseller accounts to offer hosting for customers.
Reseller Website Hosting
Reseller website hosting allows customers to be website hosts themselves. Resellers may 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 provide a nearly identical service to their provider's shared hosting plan and provide the technical 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 does not directly reflect the server's hardware. VPS will generally be allocated resources based on a one server to many VPSs relationship, however, virtualization may be chosen for different reasons, which includes the option to relocate a VPS container between servers. The users may have root access to their own virtual space. Customers 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 customer gets his or her own web server and has full control over it (user has root access for Linux/administrator access for Windows); however, the user typically 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 user 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 website server but is 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 tools. The user is not given complete control so that the provider can guarantee the quality of service by not allowing the customer to modify the server or potentially create configuration problems. The client sometimes doesn't own the server. The server is leased to the customer.
Colocation Website Hosting Service
Almost the same as the dedicated website hosting service, but the client owns the colocation server; the hosting organization provides physical space that the computer takes up and manages the computer. This is the most powerful and costly type of website hosting service. In most cases, the colocation provider may supply little to no support directly for their user's computer, providing only 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 hosts now insist on rack mount enclosures and standard system configurations.
Cloud Hosting
This is a relatively modern kind of hosting platform that allows customers strong, scalable and reliable hosting based on clustered load-balanced servers and utility billing. A cloud-hosted website may be more reliable than alternatives as other servers in the cloud can take over when a single piece of hardware stops working. Furthermore, local power outages or even natural disasters are less problematic for cloud hosted websites, as cloud hosting is decentralized. Cloud hosting also permits providers to bill users only for resources used by the client, rather than a flat rate for the amount the customer thinks they may consume, or a fixed cost upfront hardware investment. Alternatively, the decentralization may provide users less control on where their data is located, which could be challenging for customers with data security or privacy worries.
Clustered Hosting
Having a number of servers host the same content for improved resource utilization. Clustered computers are a wonderful solution for high-availability dedicated hosting, or building a scalable website hosting system. A cluster may separate website serving from database hosting capability. (Sometimes web hosts use clustered hosting for their shared hosting plans, as there are a lot of pros to the mass managing of customers).
Grid Hosting
This form of distributed hosting is when a server cluster performs like a grid and is made of multiple nodes.
Home Server
Sometimes, an individual computer located in a private residence can be used to host one or a few web sites from a typically consumer-grade broadband connection. These can be purpose-built servers or more commonly older PCs. Some internet service providers purposefully work to block home servers by blocking incoming requests to TCP port 80 of the customer's connection and by refusing to offer static IP addresses. A common 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 directs to when the IP address changes.
Some specific types of hosting provided 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 might 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 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 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 such as during network outage. A hosting provider's Service Level Agreement (SLA) might include a certain amount of scheduled downtime per year in order to perform maintenance on the systems. This 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 server drops lower than that in the signed SLA, a hosting provider often will offer a partial refund for lost time. How downtime is determined changes from provider to provider, therefore going through the SLA is important. Not all providers release uptime stats. A lot 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 every year.
Obtaining Hosting
Web hosting is generally provided as part of a larger internet access plan from internet service providers. There are also a number of free and paid providers offering web hosting.
A client must 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 number of 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 website hosting customer may want to acquire other services, such as email for their business domain, databases or multimedia services. A client 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 at times include a web content management system, so the end-user doesn't have to be concerned about the more technical parts.
Security
Because web hosting services host websites belonging to their clients, web security is a vital issue. When a customer agrees to use a website hosting service, they are relinquishing control of the security of their website to the provider 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 issue when considering which supplier a client may choose.
Website hosting server can be targeted by malicious users in different ways, including uploading malware or malicious code onto a hosted site. These attacks {may|might| be done for various reasons, including stealing credit card information, launching a Distributed Denial of Service Attack (DDoS) or spamming.
