Website Hosting Thailand
Website Hosting Thailand
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 organizations that provide space on a server owned or leased for use by users, 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 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 website browser for Mac or Windows computers. Even after there was additional internet availability, the situation was complicated until 1995.
To host a web site on the internet, an individual or organization would need their own computer system or server. As not all companies had the money or experience to do this, web site hosting services began to supply services to host users' sites on their own servers, without the customer needing to get the necessary infrastructure required to run the web site. The owners of the sites, also called webmasters, would be able to build a website that would be hosted on the web hosting service's server and published to the web by the website hosting service.
As the number of users on the world wide web grew, the pressure for organizations, both large and small, to have an online presence grew. By 1995, organizations such as GeoCities, Angelfire and Tripod were providing 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 sometimes delivered to the web "as is" or with minimal processing. A lot of internet service providers (ISPs) offer this service with no cost to users. Individuals and companies may also obtain web page hosting from other service providers.
Free web hosting service is supplied by various companies with limited services, at times supported by advertisements, and often limited when compared to paid hosting.
Single page hosting is at times sufficient for personal website pages. Personal web site hosting is typically free, advertisement-sponsored, or inexpensive. Business web site hosting generally has a higher investment depending upon the size and type of the site.
Larger Hosting Services
Many big companies that are not internet service providers need to be permanently 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 internet-based orders.
A complicated website will have a more expanded 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 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 manage web servers. The scope of website hosting services varies greatly.
Shared Website Hosting Service
One's site is found on the same server as many other sites, ranging from a few websites to hundreds of websites. Generally, 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 sometimes have reseller accounts to provide hosting for customers.
Reseller Web Hosting
Reseller web hosting permits clients to be web 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 differentiate 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 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 often be allocated resources based on a one server to many VPSs relationship, however, virtualization might be chosen for different reasons, including the ability to move a VPS container from one server to another. Users might 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 client (managed server).
Dedicated Hosting Service
The user gets his or her own website server and has complete control over it (user has root access for Linux/administrator access for Windows); but, the customer generally 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 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 they are not allowed complete control over it (the user is not given root access for Linux/administrator access for Windows); but, they are allowed to control their data via FTP or other remote management software. The customer is not given full control so that the provider can guarantee the quality of service by not granting the client to modify the server or potentially create configuration problems. The user often doesn't own the server. The server is leased to the client.
Colocation Website Hosting Service
Almost the same as the dedicated website hosting service, but the user owns the colocation server; the hosting company supplies physical space that the server takes up and manages the server. This is the strongest and expensive kind of web hosting service. In most cases, the colocation provider may supply little to no support directly for their user's computer, providing just 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 system configuration for hosting, even ones housed in desktop-style minitower cases, but most hosting companies now insist on rack mount enclosures and standard system configurations.
Cloud Hosting
This is a 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 site may be more reliable than others as other servers in the cloud can take over when an individual piece of hardware goes down. Furthermore, local power outages or even natural disasters are less problematic for cloud hosted sites, as cloud hosting is decentralized. Cloud hosting also allows providers to charge users only for resources consumed by the client, instead of a flat rate for the amount the user expects they will use, or a fixed rate upfront hardware investment. Alternatively, the decentralization may provide clients less control on where their information is located, which could be a deal breaker for customers with data security or privacy issues.
Clustered Hosting
Having a few servers host the same content for stable resource utilization. Clustered servers are a fantastic solution for high-availability dedicated hosting, or creating a scalable web hosting system. A cluster may separate web serving from database hosting capability. (Often web hosts use clustered hosting for their shared hosting plans, as there are a lot of pros to the mass managing of clients).
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 single server located in a private residence can be used to host one or a number of web sites from a usually consumer-grade broadband connection. These can be purpose-built servers or more commonly older PCs. Some internet service providers purposefully attempt to block residential servers by disallowing incoming requests to TCP port 80 of the customer's connection and by refusing to offer static IP addresses. A good method 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 directs to when the IP address changes.
Some specific types 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 can also provide 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 doesn't 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 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 computers. This 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 lower than that in the signed SLA, a hosting provider generally will offer a partial refund for lost time. How downtime is determined varies from provider to provider, therefore going through the SLA is crucial. Not all providers produce uptime statistics. A lot of hosting providers will guarantee at least 99.9% uptime which will provide 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 many free and paid providers offering web hosting.
A client should 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 various 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 obtain other services, such as email for their organization domain, databases or multimedia services. A user may also choose 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 does not have to be bothered about the more technical parts.
Security
Since web hosting services host websites belonging to their customers, internet security is an extreme worry. When a client agrees to use a web hosting service, they are handing over control of the security of their website to the service provider that is hosting the website. The amount of security that a web hosting service offers is very important to a prospective customer and can be a major subject when deciding which supplier a client should choose.
Web hosting server can be attacked by malicious organizations in various ways, including uploading malware or malicious code onto a hosted website. These attacks {may|might| be done for different reasons, such as stealing credit card data, launching a Distributed Denial of Service Attack (DDoS) or spamming.
