Yola Website Hosting
Yola Website Hosting
A web hosting service is a kind of internet hosting service that permits people 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 customers, as well as providing internet connectivity, typically in a data center. Website 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 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 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 greater internet access, the situation was complicated until 1995.
To host a web site on the internet, an individual or business would need their own computer or server. As not all organizations had the money or expertise to complete this, web hosting services started to supply services to host users' websites on their own servers, without the customer needing to build the necessary infrastructure neededd to operate the web site. The owners of the sites, also known as webmasters, would be able to build a site 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 demand for organizations, both big and tiny, 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 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 usually delivered to the web "as is" or with minimal processing. A lot of internet service providers (ISPs) supply this service free to users. Individuals and companies may also obtain web page hosting from alternative service providers.
Free website hosting service is offered by different companies with limited services, at times supported by adds, and generally 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 sometimes has a higher expense depending upon the size and type of the site.
Larger Hosting Services
Many big organizations that are not ISPs 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 offer details of their products and services and facilities for online orders.
A complicated site needs a more inclusive 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 write 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 website hosting services varies quite a bit.
Shared Website Hosting Service
One's site is placed on the same server as many other websites, ranging from a few websites to hundreds of websites. Typically, all domains may share a common pool of server resources, such as RAM and the CPU. The features available with this kind of service can be quite simple and not flexible in terms of software and updates. Resellers often sell shared website hosting and website companies sometimes have reseller accounts to supply hosting for clients.
Reseller Web Hosting
Reseller website hosting allows clients to become web hosts themselves. Resellers can function, for individual domains, under any combination of these listed 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 offer a nearly identical service to their provider's shared hosting plan and supply the technical 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 doesn't directly reflect the server's hardware. VPS will generally be allocated resources based on a one server to many VPSs relationship, but, virtualization may be chosen for a number of reasons, including the ability to relocate a VPS container from one server to another. The users might have root access to their own virtual space. Customers are sometimes responsible for patching and maintaining the server (unmanaged server) or the VPS provider may supply server admin jobs for the customer (managed server).
Dedicated Hosting Service
The user gets their own website server and gains complete control over it (user has root access for Linux/administrator access for Windows); however, the user usually 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 customer 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 his or her own web server but they are not allowed complete control over the server (the client is not given root access for Linux/administrator access for Windows); but, they may manage their data via FTP or other remote management software. The client is disallowed complete control so that the provider can guarantee the quality of service by not permitting the client to modify the server or perhaps create configuration issues. The customer typically does not own the server. The server is leased to the client.
Colocation Web Hosting Service
Similar to the dedicated web hosting service, but the client owns the colocation server; the hosting company offers physical space that the server takes up and manages the computer. This is the most powerful and costly kind of web hosting service. In most cases, the colocation provider may provide 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 their 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 companies now expect rack mount enclosures and standard system configurations.
Cloud Hosting
This is a new kind of hosting platform that allows clients strong, scalable and reliable hosting based on clustered load-balanced servers and utility billing. A cloud-hosted site may be more reliable than alternatives as other servers in the cloud can take over when an individual piece of hardware fails. Furthermore, local power disruptions or even natural disasters are less problematic for cloud hosted websites, as cloud hosting is decentralized. Cloud hosting also allows providers to invoice users just for resources used by the client, rather than a flat fee for the amount the client assumes they will consume, or a fixed cost upfront hardware investment. Alternatively, the lack of centralization may provide users less control over where their information is located, which could be an issue for customers with data security or privacy issues.
Clustered Hosting
Having a number of servers hosting the same content for stable resource utilization. Clustered servers are a amazing solution for high-availability dedicated hosting, or creating 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 quite a few pros to the mass managing of customers).
Grid Hosting
This type of distributed hosting is when a server cluster acts like a grid and is made of multiple nodes.
Home Server
Often, a single machine situated in a private residence can be used to host one or a few websites from a generally consumer-grade broadband connection. These can be purpose-built machines or more commonly older PCs. Some internet service providers purposefully try to block home servers by stopping incoming requests to TCP port 80 of the client's connection and by refusing to offer static IP addresses. A good method to have a reliable DNS hostname is by obtaining 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 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 can 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 website server that does not use a control panel for managing the hosting account, is sometimes 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 site 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 when there is a network outage. A hosting provider's Service Level Agreement (SLA) might include a specific amount of scheduled downtime per year in order to perform maintenance on the servers. 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 computer drops below that in the signed SLA, a hosting provider at times will supply a partial refund for time lost. How downtime is determined changes from provider to provider, therefore understanding the SLA is important. Not all providers publicly display uptime statistics. Most 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 each year.
Obtaining Hosting
Website hosting is at times offered as part of a larger internet access plan from ISPs. There are also a number of free and paid providers offering web hosting.
A customer needs to 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 lot of hosting providers offer 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 web hosting customer may want to acquire other services, such as email for their organization domain, databases or multimedia services. A user might also prefer 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 often include a web content management system, so the end-user does not have to be bothered about the more technical components.
Security
Since website hosting services host websites which belong to their clients, internet security is an important topic. When a customer agrees to use a web hosting service, they are handing over control of the security of their website to the company that is hosting the site. The level of security that a web hosting service provides is very important to a possible client and can be a major component when considering which supplier a client may choose.
Website hosting computers can be targeted by malicious people in different 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 information, launching a Distributed Denial of Service Attack (DDoS) or spamming.
