Best Php Website Hosting
Best Php Website Hosting
A web hosting service is a kind of internet hosting service that allows people and companies to make their website accessible via the world wide web. Web hosts are companies that provide 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 established and not until the end of 1993 would there be a graphical web site browser for Mac or Windows computers. Even after there was increased internet availability, the situation was challenging until 1995.
To host a web site on the internet, a person or organization would need their own computer system or server. As not all companies had the money or capability to do this, web site hosting services started to offer to host users' sites on their own servers, without the client needing to configure the necessary infrastructure required to run the website. The owners of the sites, also called webmasters, would be able to create a site 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 world wide web increased, the demand for companies, both big and tiny, to have an online presence grew. By 1995, organizations such as GeoCities, Angelfire and Tripod were offering 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 site interface. The files are typically delivered to the web "as is" or with almost no processing. Many internet service providers (ISPs) provide this service free to users. Individuals and organizations may also get website page hosting from alternative service providers.
Free website hosting service is offered by different companies with limited services, sometimes supported by adds, and often 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 sometimes has a higher investment depending upon the size and type of the site.
Larger Hosting Services
Many big organizations that are not ISPs need to be permanently connected to the web to send email, files, etc. to other sites. The company may use the computer as a website host to offer details of their goods and services and facilities for online orders.
A complex website will have 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 web hosting services varies greatly.
Shared Web Hosting Service
One's site is found on the same server as many other websites, ranging from a few sites to hundreds of sites. Typically, 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 fairly simple and not flexible in terms of software and updates. Resellers at times sell shared web hosting and web companies at times have reseller accounts to offer hosting for clients.
Reseller Web Hosting
Reseller web hosting allows customers to take on the role of 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 fair amount 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
This is also known as a Virtual Private Server (VPS), it divides server resources into virtual servers, where resources can be split up in a way that doesn't directly reflect the shared hardware. VPS will sometimes be allocated resources based on a one server to many VPSs relationship, but, virtualization might be done for different reasons, which includes the option to move a VPS container from one server to another. Users might have root access to their own virtual space. Clients are often 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 client gets their own web server and gains absolute control over it (user has root access for Linux/administrator access for Windows); however, the client generally does not own the server. One kind of dedicated hosting is self-managed or unmanaged. This is typically the least expensive for dedicated plans. The client has full administrative access to the server, which means the client is responsible for the security and maintenance of their own dedicated server.
Managed Hosting Service
The client gets his or her own website server but is not allowed complete control over the server (the customer is denied root access for Linux/administrator access for Windows); however, they may manage their data via FTP or other remote management software. The customer is not granted complete control so that the provider can guarantee the quality of service by not giving the user to change the server or potentially create configuration problems. The customer generally does not own the server. The server is leased to the customer.
Colocation Website Hosting Service
Almost the same as the dedicated web hosting service, but the client owns the colocation server; the hosting organization offers physical space that the computer takes up and manages the computer. This is the strongest and costly type of web hosting service. In most cases, the colocation provider may offer little to no assistance directly for their customer's server, providing only the electrical, internet access, and storage facilities for the computer. In most cases for colocation, the user would have their own administrator go to the data center on-site to do any hardware upgrades or changes. Formerly, many colocation providers would allow any server configuration for hosting, even ones housed in desktop-style minitower cases, but most hosting organizations now expect rack mount enclosures and standard system configurations.
Cloud Hosting
This is a relatively modern type of hosting platform that permits clients powerful, scalable and reliable hosting based on clustered load-balanced servers and utility billing. A cloud-hosted website may be more reliable than others since other servers in the cloud can take over when a single piece of hardware goes down. Furthermore, local power failures or even natural disasters are less of a problem for cloud hosted sites, as cloud hosting is decentralized. Cloud hosting also allows providers to invoice users only for resources used by the customer, instead of a flat rate for the amount the customer assumes they may consume, or a fixed cost upfront hardware investment. Alternatively, the lack of centralization may give users less control over where their information is located, which could be a deal breaker for customers with data security or privacy issues.
Clustered Hosting
Having multiple servers host the same content for stable resource utilization. Clustered servers are a amazing solution for high-availability dedicated hosting, or having a scalable web hosting system. A cluster may separate web serving from database hosting capability. (Typically website hosts use clustered hosting for their shared hosting plans, as there are many pros to the mass managing of customers).
Grid Hosting
This form of distributed hosting is when a server cluster acts like a grid and is made of multiple nodes.
Home Server
Sometimes, a sole machine placed 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 computers or more commonly older PCs. Some ISPs actively work to block home servers by not allowing incoming requests to TCP port 80 of the user's connection and by refusing to provide static IP addresses. A quick way to have a reliable DNS hostname is by creating an account with a dynamic DNS service. A dynamic DNS service will automatically update the IP address that a URL points to when the IP address changes.
Some specific kinds of hosting offered 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 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 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 site is publicly available 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 certain amount of scheduled downtime per year in order to perform maintenance on the servers. This scheduled downtime is generally 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 sometimes will offer a partial refund for lost time. How downtime is determined changes from provider to provider, therefore examining the SLA is imperative. Not all providers produce uptime statistics. 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 per year.
Obtaining Hosting
Website hosting is generally provided as part of a complete internet access plan from internet service providers. There are also a number of free and paid providers offering website 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. Most hosting providers supply Linux-based website 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 client might want to acquire other services, such as email for their business domain, databases or multimedia services. A user might also choose Windows as the hosting platform. The client still can choose from Perl, PHP, Python, and Ruby, but the user may also use ASP.NET or ASP Classic. Web hosting packages sometimes include a web content management system, so the end-user doesn't have to worry about the more technical parts.
Security
Because website hosting services host websites belonging to their customers, web security is a very important item. When a client agrees to use a website hosting service, they are giving up control of the security of their website to the provider that is hosting the website. The amount of security that a website hosting service supplies is quite important to a prospective client and can be a major item when deciding which supplier a customer may choose.
Website hosting server 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, including stealing credit card data, launching a Distributed Denial of Service Attack (DDoS) or spamming.
