Instant activation
Hosts with instant activation usually give very little storage space and bandwidth allowance, and have lots of limitations. The webhosts usually either require the users' web pages to display their banner ads, textlink ads, or popups; or else the users' files to be uploaded through a web-based file manager that display ads to the user uploading files.
Hosts with instant activation are often abused by spammers, which upload pages to these hosts to use for link spamming
Approved activation
Hosts with approved activation offer good space and Bandwidth but low on features. Approved applications are processed by administrators hired by the free hosting company who validate the applications depending on the details provided by the users. The main objective behind manual approval is to prevent spam and phishing websites.
Activation time can be as low as few minutes or as long as a week. Different hosts have different policies for Approval and Activation
Post for hosting
Some free hosts require posting in a forum. Forum-based free hosting requires users to either reach a certain amount of posts before getting a free hosting account, or be an active contributor in the forum. Forum-based free hosting often work on a system of points where posts give points to a user and can be used as credits toward getting a hosting account or more resources. Typically, the forum where users have to post contain advertising as the hosts way of making a profit.
A typical example of this system would be to post to gain "credits" (points). Perhaps every credit is equivalent to 24 hours or a day. So, if you make a post and get 7 credits, Your hosting account would be active for 7 days. While some hosts allow these credits to be distributed, others do not. However, when they are allowed to be distributed, they might be used as a currency in exchange for services.
Forum applications
This method is popular, as the hosts can decide which applications to deny and allow. This is common when a popular forum has free hosting as an add-on service, rather than the other way around
File hosting on Webhosts
Most free web hosts discourage using their services for file or image hosting only, with no web page, since advertising is displayed on the web page. Because of this, hotlinking is usually disallowed on free hosts. Some free webhosts will also disallow files over a certain size (for example, 5 MB). However, there are free file hosting serviceswhich allow large files as well as hotlinking.
Co-branding and resellers
Some services offer co-branding services. These let you brand fixed plans with your own company. Other services, offer WHM or panel reselling. This allows the client to develop his or her own web hosting plans and business.

Clustered Hosting
Clustered hosting technology is designed to eliminate the problems inherent with typical shared hosting infrastructures. This technology provides customers with a “clustered” handling of security, load balancing, and necessary website resources.
A clustered hosting platform is data-driven, which means that no human interaction is needed to provision a new account to the platform.
Clustered hosting "virtualizes" the resources beyond the limits of one physical server, and as a result, a website is not limited to one server. They share the processing power of many servers and their applications are distributed in real-time. This means that they can purchase as much computing power as they want from a virtually inexhaustible source, since even the largest customer never consumes more than a fraction of a percent of the total server pool. Customer account changes (to add new resources or change settings) are propagated immediately to every server in the cluster. This is different from typical shared hosting architectures that usually require changes to a configuration file that becomes live after the server is rebooted during off hours, or are pushed on a cyclic basis every few hours.
Multiple tiers of security are integrated into the clustered hostingplatform. In a typical hosting environment, the security layer is usually not integrated in the platform. The stock solutions used for shared hosting do not solve core issues around integrating security between the application and the operating system. At best, most typical hosts will implement a firewall solution, and weaknesses inherent with the operating system will remain exploitable to those that penetrate the firewall.
Clustered hosting network layer protections employ intelligentrouting, redundant switching fabric and built in firewall and proxytechnology. Clustered hosting provides considerable advantages over traditional hosting architectures in mitigating denial-of-service attacks and other network attacks because such attacks can be dispersed over a large pool of servers, and if individual hardwarecomponents are impacted by such attacks, they automatically fall out of traffic handling during the attack.

Reseller Wbhosing
Reseller hosting is a form of web hosting wherein the account owner has the ability to use his/her allotted hard drive space and bandwidthto host websites on behalf of third parties. The reseller purchases the host's services wholesale and then sells them to his customers for a profit. The certain portion of hard drive and bandwidth is allocated to reseller account. In order to achieve this the reseller may rent a dedicated server from a hosting company or resell shared hosting services. If the latter is the case the reseller is simply given the permission to sell a certain amount of disk space and bandwidth to his own customers without renting a server from a web hosting company he signed for a reseller account with.
The typical web hosting reseller might be a web design firm, web developer or systems integrator who offers web hosting as an add-on service. Reseller hosting is also an inexpensive way for web hosting entrepreneurs to start a company. Most reseller hosting plans allow resellers to create their own service plans and choose their own pricing structure. In many cases, resellers are able to establish their own branding via customized control panels and name servers.
Reseller hosting does not require extensive knowledge of the technical aspects of web hosting. Usually, the data center operator is responsible for maintaining network infrastructure and hardware, and the dedicated server owner configures/secures/updates the server. A reseller is responsible for interfacing with his/her own customer base, but any hardware, software and connectivity problems are typically forwarded to the server provider from whom the reseller plan was purchased.
Through point and click "Control Panels" (as listed below), resellers can set up and manage customer accounts via a web interface. In addition, the ModernBill software is popular among resellers, as it automates account creation and billing. Most of the reseller hosting companies offers different reseller hosting plans as cpwebhosting proposes five of the its reseller hosting plans: 1. Starter Reseller Hosting 2. Beginner Reseller Hosting 3. Professional Reseller Hosting 4. Prime Reseller Hosting 5. Professional Reseller Hosting

Bandwidth and connectivity
Bandwidth refers to the data transfer rate or the amount of data that can be carried from one point to another in a given time period (usually a second) and is often represented in bits (of data) per second (bit/s). For example, visitors to your server, web site, or applications utilize bandwidth as the traffic moves from your server to the Internet and vice versa. Connectivity refers to the “access providers” that supply bandwidth, or data transfer rate, through various connection points across a network or footprint to one or multiple data centers where dedicated servers are housed.
Bandwidth measurements are defined (per telecom standards) as the following:
First – 95th (measured using average bits and speed of transfer)
Second – Unmetered (measured in speed or bits)
Third – Total Transfer (measured in bytes transferred)
95th Method: line speed, billed on the 95th percentile, average or peak usage, refers to the speed in which data flows from the server or device. Line speed is measured in bits per second (or kilobits per second, megabits per second or gigabits per second).
Unmetered Method: The second bandwidth measurement is unmetered service where providers cap or control the “top line” speed for a server. Top line speed in unmetered bandwidth is the total Mbit/s allocated to the server and configured on the switch level. For example, if you purchase 10 Mbit/s unmetered bandwidth, the top line speed would be 10 Mbit/s. 10 Mbit/s would result in the provider controlling the speed transfers take place while providing the ability for the dedicated server owner to not be charged with bandwidth overages. Unmetered bandwidth services usually incur an additional charge.
Total Transfer Method: Some providers will calculate the Total Transfer, the measurement of actual data leaving and arriving, measured in bytes. Measurement between providers varies and includes one of the following equations:
Method 1: IN TRAFFIC + OUT TRAFFIC = TOTAL TRANSFER
Method 2: IN TRAFFIC = TOTAL TRANSFER
Method 3: OUT TRAFFIC = TOTAL TRANSFER
One of the reasons for choosing to outsource dedicated servers is the availability of high powered networks from multiple providers. As dedicated server providers utilize massive amounts of bandwidth, they are able to secure lower volume based pricing to include a multi-provider blend of bandwidth. To achieve the same type of network without a multi-provider blend of bandwidth, a large investment in core routers, long term contracts, and expensive monthly bills would need to be in place. The expenses needed to develop a network without a multi-provider blend of bandwidth does not make sense economically for hosting providers.
Many dedicated server providers include a service level agreement based on network uptime. Some dedicated server hosting providers offer a 100% uptime guarantee on their network. By securing multiple vendors for connectivity and using redundant hardware, providers are able to guarantee higher uptimes; usually between 99-100% uptime if they are a higher quality provider. One aspect of higher quality providers is they are most likely to be multi-homed across multiple quality uplink providers, which in turn, provides significant redundancy in the event one goes down in addition to potentially improved routes to destinations.
Bandwidth consumption over the last several years has shifted from a per megabit usage model to a per gigabyte usage model. Bandwidth was traditionally measured in line speed access that included the ability to purchase needed megabits at a given monthly cost. As the shared hosting model developed, the trend towards gigabyte or total bytes transferred, replaced the megabit line speed model so dedicated server providers started offering per gigabyte.
Prominent players in the dedicated server market offer large amounts of bandwidth ranging from 500 gigabytes to 3000 gigabytes using the “overselling” model. It is not uncommon for major players to provide dedicated servers with 1Terabyte (TB) of bandwidth or higher. Usage models based on the byte level measurement usually include a given amount of bandwidth with each server and a price per gigabyte after a certain threshold has been reached. Expect to pay additional fees for bandwidth overage usage. For example, if a dedicated server has been given 3000 gigabytes of bandwidth per month and the customer uses 5000 gigabytes of bandwidth within the billing period, the additi

Management
To date, no industry standards have been set to clearly define the management role of dedicated server providers. What this means is that each provider will use industry standard terms, but each provider will define them differently. For some dedicated server providers, fully managed is defined as having a web based control panel while other providers define it as having dedicated system engineers readily available to handle all server and network related functions of the dedicated server provider.
Server management can include some or all of the following:
Operating system updates
Application updates
Server monitoring
SNMP hardware monitoring
Application monitoring
Technical support
Firewall services
Antivirus updates
Security audits
DDoS protection and mitigation
Intrusion detection
Backups and restoration
Disaster recovery
DNS hosting service
Load balancing
Database administration
Performance tuning
Software installation and configuration
User management
Programming consultation
Dedicated hosting server providers define their level of management based on the services they provide. In comparison, fully managed could equal self managed from provider to provider.
Administrative maintenance of the operating system, often including upgrades, security patches, and sometimes even daemon updates are included. Differing levels of management may include adding users, domains, daemon configuration, or even custom programming.
Dedicated server hosting providers may provide the following types of server managed support:
Fully Managed - Includes monitoring, software updates, reboots, security patches and operating system upgrades. Customers are completely hands-off.
Managed - Includes medium level of management, monitoring, updates, and a limited amount of support. Customers may perform specific tasks.
Self Managed - Includes regular monitoring and some maintenance. Customers provide most operations and tasks on dedicated server.
Unmanaged - Little to no involvement from service provider. Customers provide all maintenance, upgrades, patches, and security.
Note: The provider will continue to maintain security on the network regardless of support level.

Limitations
Many providers do not allow IRC (bots, clients or daemons). This is due to rogue IRC users triggering DDoS attacks against the provider, which may overwhelm their networks, lowering service quality for all customers.
Adult content is disallowed by many providers as it may either be of questionable legality or consume large amounts of bandwidth.
Copyright violation Hosting copyrighted material of which you do not own the copyright to is almost always against the terms of service of all hosting companies.
