Asp Net Core Website Hosting
Asp Net Core Website Hosting
A web hosting service is a kind of internet hosting service that allows individuals and companies to make their website accessible via the world wide web. Website 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 offer 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 small number of website pages. The world wide web protocols had only just been put together and not until the end of 1993 would there be a graphical web browser for Mac or Windows computers. Even after there was additional internet availability, the situation was convoluted until 1995.
To host a web site on the internet, an individual or company would need their own computer system or server. As not all organizations had the budget or expertise to complete this, website hosting services started to supply services to host users' websites on their own servers, without the customer needing to configure the necessary infrastructure neededd to operate the website. The owners of the websites, also referred to as webmasters, would be able to create a website 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 internet grew, the pressure for companies, both big and small, to have an online presence grew. By 1995, companies such as GeoCities, Angelfire and Tripod were offering free hosting.
Classification
Smaller Hosting Services
The simplest is awebsite page and small-scale file hosting, where files can be uploaded via File Transfer Protocol (FTP) or a website interface. The files are usually delivered to the web "as is" or with very little processing. A lot of internet service providers (ISPs) offer this service free of charge to users. People and companies may also obtain web page hosting from alternative service providers.
Free website hosting service is provided by various organizations with limited services, sometimes supported by advertisements, and at times limited when compared to paid hosting.
Single page hosting is sometimes sufficient for personal web pages. Personal web site hosting is typically free, advertisement-sponsored, or inexpensive. Business web site hosting generally has a greater expense 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 provide details of their goods and services and facilities for internet-based orders.
A complicated site calls for a more comprehensive package that offers database support and application development platforms (e.g. ASP.NET, ColdFusion, Java EE, Perl/Plack, PHP or Ruby on Rails). These programs allow clients to develop 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 safe.
Types of Hosting
Internet hosting services can manage web servers. The scope of website hosting services varies quite a bit.
Shared Web Hosting Service
One's website is placed on the same server as many other sites, ranging from a few sites 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 fairly basic and not flexible in terms of software and updates. Resellers sometimes make available shared web hosting and web companies at times have reseller accounts to supply hosting for clients.
Reseller Web Hosting
Reseller web hosting permits 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 differentiate tremendously in size: they may have their own virtual dedicated server to a colocated server. Many resellers supply a similar 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 generally be allocated resources based on a one server to many VPSs relationship, but, virtualization might be desired for different reasons, which includes the possibility to relocate a VPS container from one server to another. Users might have root access to their own virtual space. Customers are often responsible for fixing and maintaining the server (unmanaged server) or the VPS provider may provide server admin jobs for the customer (managed server).
Dedicated Hosting Service
The customer gets their own website server and has complete control over it (user has root access for Linux/administrator access for Windows); however, the client often doesn't own the server. One type of dedicated hosting is self-managed or unmanaged. This is often the least expensive for dedicated plans. The customer has full admin access to the server, which means the user is responsible for the security and maintenance of their own dedicated server.
Managed Hosting Service
The customer gets his or her own website server but is not allowed full control over it (the user is denied root access for Linux/administrator access for Windows); but, 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 permitting the customer to change the server or potentially create configuration problems. The client typically doesn't own the server. The server is leased to the user.
Colocation Website Hosting Service
Similar to the dedicated website hosting service, but the client owns the colocation server; the hosting company offers physical space that the computer takes up and manages the server. This is the most powerful and costly kind of web hosting service. In most cases, the colocation provider may supply little to no assistance directly for their client's machine, providing just the electrical, internet access, and storage facilities for the server. In most cases for colocation, the customer 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 server configuration for hosting, even ones housed in desktop-style minitower cases, but most hosting companies now require rack mount enclosures and standard system configurations.
Cloud Hosting
This is a relatively new type of hosting platform that allows clients powerful, scalable and reliable hosting based on clustered load-balanced servers and utility billing. A cloud-hosted website may be more stable than alternatives since other servers in the cloud can compensate when a single piece of hardware goes down. Also, local power outages or even natural disasters are less problematic for cloud hosted sites, as cloud hosting is decentralized. Cloud hosting also permits providers to charge users only for resources consumed by the client, rather than a flat amount for the amount the customer expects they might use, or a fixed amount upfront hardware investment. Alternatively, the decentralization might give clients less control on where their data is located, which could be a deal breaker for clients with data security or privacy concerns.
Clustered Hosting
Having a bunch of servers hosting the same content for improved resource utilization. Clustered servers are a sturdy solution for high-availability dedicated hosting, or building a scalable website hosting solution. A cluster may separate web serving from database hosting capability. (Typically web hosts use clustered hosting for their shared hosting plans, as there are quite a few benefits to the mass managing of clients).
Grid Hosting
This variation of distributed hosting is when a server cluster performs like a grid and is composed of multiple nodes.
Home Server
Often, a single server situated in a private home can be used to host one or a number of web sites from a usually consumer-grade broadband connection. These can be purpose-built computers or more commonly older PCs. Some internet service providers actively try to block residential servers by stopping incoming requests to TCP port 80 of the customer's connection and by refusing to offer static IP addresses. A quick way to keep 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 directs to when the IP address changes.
Some specific types 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 may 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 web 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 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 as in the event of a 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 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 system drops below that in the signed SLA, a hosting provider often will offer a partial refund for lost time. How downtime is calculated changes from provider to provider, therefore understanding the SLA is important. Not all providers show uptime information. Quite a number of 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
Web hosting is at times provided as part of a general internet access plan from ISPs. There are also a lot of free and paid providers offering website hosting.
A client 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. Most hosting providers provide 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 web hosting user may want to have 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 generally include a web content management system, so the end-user does not have to be concerned about the more technical components.
Security
Because website hosting services host websites which belong to their clients, web security is a vital concern. When a client agrees to use a web hosting service, they are handing over control of the security of their website to the provider that is hosting the site. The level of security that a website hosting service provides is very important to a prospective client and can be a major subject when considering which supplier a client may choose.
Website hosting computers can be attacked by malicious users in different ways, including uploading malware or malicious code onto a hosted site. These attacks {may|might| be done for different reasons, such as stealing credit card info, launching a Distributed Denial of Service Attack (DDoS) or spamming.
