Blogspot Free Website Hosting
A web 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 organizations that offer space on a server owned or leased for use by customers, as well as providing internet connectivity, typically 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
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 website 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 browser for Mac or Windows computers. Even after there was increased internet access, the situation was convoluted until 1995.
To host a website on the internet, a person or business would need their own computer or server. As not all organizations had the budget or expertise to complete this, web site hosting services began to supply services to host users' sites on their own servers, without the client needing to configure the necessary infrastructure required to operate the website. The owners of the websites, also referred to as webmasters, would be able to design a website that would be hosted on the web hosting service's server and published to the internet by the web hosting service.
As the number of users on the world wide web increased, the demand for organizations, both large and small, to have an online presence grew. By 1995, companies 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 web site interface. The files are usually delivered to the web "as is" or with very little processing. A lot of internet service providers (ISPs) provide this service with no cost to subscribers. Individuals and companies may also get website page hosting from alternative service providers.
Free web hosting service is offered by various organizations with limited services, sometimes supported by advertisements, and often limited when compared to paid hosting.
Single page hosting is at times sufficient for personal web pages. Personal web site hosting is typically free, advertisement-sponsored, or inexpensive. Business web site hosting generally has a greater cost depending upon the size and type of the site.
Larger Hosting Services
Many big organizations that are not internet service providers need to be constantly connected to the web in order to send email, files, etc. to other sites. The organization may use the computer as a website host to provide details of their products and services and facilities for website orders.
A complicated site requires a more expanded package that supplies database support and application development platforms (e.g. ASP.NET, ColdFusion, Java EE, Perl/Plack, PHP or Ruby on Rails). These options allow customers to write 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 website hosting services varies quite a bit.
Shared Web Hosting Service
One's website is found on the same server as many other sites, ranging from a few websites to hundreds of sites. Usually, 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 basic and not flexible in terms of software and updates. Resellers sometimes sell shared web hosting and web organizations at times have reseller accounts to supply hosting for customers.
Reseller Web Hosting
Reseller website hosting permits clients to become website hosts themselves. Resellers can function, for individual domains, under any combination of these types of hosting, depending on who they are affiliated with as a reseller. Resellers' accounts may vary tremendously 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 provide 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 allocated in a way that does not directly reflect the shared hardware. VPS will at times be allocated resources based on a one server to many VPSs relationship, however, virtualization might be desired for a few reasons, including the possibility to relocate a VPS container from one server to another. The users may have root access to their own virtual space. Clients are sometimes responsible for fixing and maintaining the server (unmanaged server) or the VPS provider may provide server administration tasks for the customer (managed server).
Dedicated Hosting Service
The user gets his or her own website server and gets full control over it (user has root access for Linux/administrator access for Windows); but, the customer often 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 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 user gets his or her own website server but they are not allowed full control over the server (the user is denied root access for Linux/administrator access for Windows); however, they are allowed to manage their data via FTP or other remote management software. The client is not given complete control so that the provider can guarantee the quality of service by not allowing the user to change the server or potentially create configuration issues. The user generally does not own the server. The server is leased to the user.
Colocation Website Hosting Service
Similar to the dedicated web hosting service, but the customer owns the colocation server; the hosting company supplies physical space that the computer takes up and takes care of the server. This is the strongest and expensive type of web hosting service. In most cases, the colocation provider may offer little to no assistance directly for their customer's machine, providing only 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 lot of colocation providers would allow 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 relatively new kind of hosting platform that permits customers strong, scalable and reliable hosting based on clustered load-balanced servers and utility billing. A cloud-hosted site might be more stable than alternatives since other servers in the cloud can compensate when a single piece of hardware stops working. Also, local power failures or even natural disasters are less problematic for cloud hosted sites, as cloud hosting is decentralized. Cloud hosting also permits providers to bill users only for resources used by the client, rather than a flat fee for the amount the client thinks they will use, or a fixed amount upfront hardware investment. Alternatively, the lack of centralization may give customers less control over where their information is located, which could be a deal breaker for clients with data security or privacy concerns.
Clustered Hosting
Having a group of servers host the same content for better resource utilization. Clustered computers are a solid solution for high-availability dedicated hosting, or creating a scalable website hosting system. A cluster may separate web serving from database hosting capability. (Generally website hosts use clustered hosting for their shared hosting plans, as there are quite a few pros to the mass managing of customers).
Grid Hosting
This variation of distributed hosting is when a server cluster acts like a grid and is made of multiple nodes.
Home Server
Generally, a single machine situated in a private residence can be used to host one or a few sites from a generally consumer-grade broadband connection. These can be purpose-built servers or more commonly older PCs. Some internet service providers actively work to block residential servers by not allowing incoming requests to TCP port 80 of the customer's connection and by refusing to provide static IP addresses. A well-known way to have 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 points to when the IP address changes.
Some specific kinds of hosting offered by web 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 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 website server that doesn't 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 site 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 during network outage. A hosting provider's Service Level Agreement (SLA) may include a reasonable amount of scheduled downtime each year in order to perform maintenance on the servers. The scheduled downtime is at times excluded from 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 below that in the signed SLA, a hosting provider generally will supply a partial refund for time lost. How downtime is calculated is different from provider to provider, therefore examining the SLA is imperative. Not all providers provide uptime stats. Quite a few hosting providers will guarantee at least 99.9% uptime which will allow for 43 minutes of downtime each month, or 8 hours and 45 minutes of downtime every year.
Obtaining Hosting
Website hosting is sometimes offered as part of a general internet access plan from internet service providers. 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 kind of hosting to use. Such considerations include database server software, scripting software, and operating system. A number of hosting providers offer Linux-based website 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 client may want to obtain other services, such as email for their organization domain, databases or multimedia services. A client might also prefer Windows as the hosting platform. The customer still can choose from Perl, PHP, Python, and Ruby, but the user 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 parts.
Security
Since website hosting services host websites belonging to their clients, internet security is a very important topic. When a customer agrees to use a web hosting service, they are giving up 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 subject when considering which supplier a client should choose.
Website hosting computers can be targeted by malicious users in various ways, which include uploading malware or malicious code onto a hosted site. These attacks {may|might| be done for different reasons, including stealing credit card data, launching a Distributed Denial of Service Attack (DDoS) or spamming.
