Here, space based web hosting system refers to the web hosting service according to sharing the space on the server. The different types of space based web hosting system perform differently on the web. We have covered the basic information about a range of space based web hosting system and their relevant pros and cons.
According to space sharing, the types of web hosting are:
1. Dedicated Web Hosting
Dedicated hosting is somewhat complicated but best suitable for those who want to manage their own entire server free from sharing with others. This is because the user is the owner of the entire server and does not share with another company. It also helps the user to have access to all its resources to host one or more websites. Unlimited database, unlimited email addresses as well as unlimited bandwidth of 500 GB to 1 TB per month are some of the qualitative features of dedicated hosting. Thus it is good for those who want more storage and bandwidth and control over the server. Except some lacunae like expensiveness and higher skill that it requires, it is good for big business houses having excellent features such as high traffic, high quality physical infrastructure, high speed internet connectivity, multiple domain names and powerful database support.
Types of Plans:
There are four types of dedicated web hosting plans:
a) Managed — it is controlled by the hosting company.
b) Unmanaged — this is complicated and takes more time, but allows the user to have greatest amount of control and flexibility as user is the server administrator.
c) Fully Managed — it is a completely hands-off plan that helps customers with facilities like monitoring, software updates, reboots, security patches and operating system upgrades. Customers are completely hands-off.
d) Self Managed — customers are provided most operations and tasks include regular monitoring and some maintenance.
Operating System Support
Depending upon the availability, price and employee familiarity a range of operating systems are offered on dedicated servers viz., Linux, Microsoft Window Server etc. Customers are not charged for using variations of Linux (open source OS). Microsoft Windows Server, a commercial operating system is provided through a special program called Microsoft SPLA. This apart, other OS are available from the open source community at no charge include CentOS, Fedora Core, Debian, and other Linux distributions or BSD systems viz., FreeBSD, NetBSD, OpenBSD.
Operating system updates and support depends on the level of management offered with the particular dedicated server plan. The range of supports include updates to the core operating systems, which include Kernel upgrades, service packs, application updates and security patches that keep server secure and sage.
2. Virtual Private Server (VPS) Hosting
A Virtual Private Server (VPS) is a segment of a single server but performs and executes like a stand-alone server. In other way, a VPS is a method of partitioning a physical server into multiple servers in such a way that each has the appearance and capabilities of running on its own dedicated machine. A VPS allows each virtual server to run its own operating system, reboot independently, and has its own root access, IP addresses, memory, processes, files, applications, system libraries and configuration files.
A VPS combines the benefits of both shared hosting and dedicated hosting, gives the same level of root access as a dedicated server, virtually run your own server but all these benefits are available at a fraction of the cost. The full root access allows you to wholly customise the virtual server, add or change modules and install any software that runs on the OS.
Each virtual server acts as its own and the host server manages the access of each private server to hardware resources such as RAM, CPU, Disk Space, Memory, Network throughput etc.
Most of the virtual private server plans are hosted on Linux or FreeBSD operating system as well as Windows too.
Earlier, partitioning of a single server into many was a common practice with mainframe computers only but with the development of virtualization software and technologies the virtual private server has been common for other architectures too.
Benefits of VPS:
Cost savings – The cost of a virtual server is low because a single physical server is shared among several users. It also saves your cost on hardware by sharing system resources.
Guaranteed performance — You always get the resources you deserve.
Easy administration — Full root-level access and Plesk 8.6.1 control panel and Virtuozzo Power Panel makes everyday administration easier.
User friendly — Reboot your system online, and repair and restore from backups.
Flexibility — Install whatever software you need. Host other services like mail server, FTP server or any other that you want.
Security – A VPS keeps your system completely safe and secure.
The physical server boots normally. It then runs a program that boots each virtual server within a virtualization environment. The virtual servers have no direct access to hardware and are usually booted from a disk image.
Kind of Virtualizations:
a) Software based — the virtual machines share the same kernel and require the main node's resources. The tools of quota incrementing and decrementing in real time without restarting the node are the key advantage of software base virtualizations. For examples: Xen, Virtuozzo, Vserver, and OpenVZ.
b) Hardware based — the mechanism partitions the real hardware resources. No real time quota modification is possible. Limits are hard and can be modified by restarting a virtual machine instance. Its security is dependent on the correctness of a larger and more complicated trusted computing base. Primarily used in enterprise and commercial deployments. For example: Microsoft Virtual Server, VMware ESX Server, and Xen.
3. Managed Web Hosting
Managed web hosting is the most popular and user friendly type of dedicated web hosting designed particularly for those businesses and individuals who need an enterprise level web hosting, best suits to their interest. Managed web hosting is normally sold to individuals who runs large and important websites, or to businesses that want to host mission critical websites with their chosen web hosting provider. Such individuals or businesses should purchase a fully managed dedicated server which allows them to upload all the website files they need but at the same time leave their server to run without any hitch.
So, if you want to host an advanced website but are not sure whether you will be able to manage your web hosting package then managed web hosting ensures you that your web hosting package will be managed on your behalf. It however can leave you without some of the freedom that you have on an unmanaged web hosting package of any sort.
Managed web hosting providers provides full support round the clock, round the calendar to the clients who are incapable of managing such a web hosting packages. The support team manages the web hosting package, which in most cases is a server, on behalf of the client. Web hosting support teams are normally very experienced so they can solve any problems that you may have.
As it is more or less infeasible for smaller web hosting companies to offer such a high cost service, it are the professional web hosting companies that provide large and organised support teams capable of dealing with high support demand which allows them to manage clients web hosting packages on their behalf.
The only drawback that managed web hosting can be said to have is in terms of its cost which is more than unmanaged or semi-managed web hosting for the simple reason that web hosting providers have to pay for an experienced support team that helps you receive the right level of customer service that you deserve.
Moreover, the hosting company takes responsibility of everything in case of the managed web hosting in comparison to the unmanaged web hosting where you are though provided bandwidth, physical security and rack space but there you are responsible for maintenance, monitoring and upgrades of your system too.
So if you are completely new to web hosting or feel that you are destitute of the required knowledge or confidence to manage a web hosting package then managed web hosting is the best hosting option for you that will allow you to upload your website and leave it to run without a second thought.
Benefits of managed web hosting:
4. Shared Web Hosting
As the name suggests the shared web hosting aka virtual hosting means that a plethora of accounts run from a singer server, sharing the capacity as well as the bandwidth. In other way, the user's website gets its own domain name, and is hosted on a powerful server together with many other websites. Shared hosting is inexpensive and supports the user with multiple software solutions such as email, database and different editing options.
In comparison to the dedicated hosting where there is a single owner and one account gets all the capacity and all the bandwidth, shared hosting deals with multiple accounts and all the users share all the capacity and the bandwidth but run from a single server.
Some of the good features of the shared web hosting are low cost as cost is shared with others, multiple software options, own domain name, good technical support which makes it a good web host option for small business and average traffic.
It has some bad features too that restricts its growth. Some of these can be counted as reduced security owing to many sites on one server, restricted data base support, restricted software support and restrictions on traffic volume, among others.
The IPS provider is generally responsible for managing servers, installing server software, security updates, technical support, and other aspects of the service. A large portion of the shared web hosting market is driven through pay per click (PPC) advertising or Affiliate programs.
Most servers are based on the Linux operating system and LAMP (software bundle), which is driven by the low cost of open source software. But some providers offer Microsoft Windows-based or FreeBSD-based solutions. Versions for either OS generally have very similar interfaces and functionality, except for OS-specific differences; for instance, ASP.NET, SQL Server and Access support under Windows while MySQL under Linux.
Two ways to get shared web hosting:
a) Name based – aka shared IP hosting, the virtual hosts serve multiple host names with a single IP address. When a web browser requests a resource from a web server using HTTP/1.1, the server in turn uses this information to determine which website to show the user.
b) IP-based – aka dedicated IP hosting, each virtual host has a different IP address. On getting request from a web browser for a resource, the web server software uses the IP address the clients connect to in order to determine which website to show the user.
5. Collocation Hosting
Collocation hosting is something like running your own server in your office but physically house your hardware and equipments at a place better designed for it, preferably a service provider's premises. A host of resources include a secured cage or rack, regulated power, dedicated Internet connection, high bandwidth, security and support are provided by the hosting company for the collocation hosting.
Companies that offer collocation are being set up at various points globally to provide services to the mushrooming web hosting and e-commerce marketplace with offering facilities such as video surveillance, fire detection and extinguishing devices, multiple connection feeds, backup power generators which is also mandatory for them to provide to their customers. A safe and secure collocation facility helps you to get rid of menace of fire, theft or vandalism, chances of which is much greater in your office or warehouse where you keep your server.
The good features of collocation hosting can be counted as high bandwidth, high up time, high security and unlimited software options. This apart some other characteristics are fast Internet connection, high bandwidth, large amount of storage space, the servers are fast, powerful and high-capacity, update/upgrade at will, greater control over web server administration, less dependency on external customer support devices, greater flexibility etc.
Despite these features one should not opt for collocation hosting if it does not possess the resources to administer the web server, maintain and upgrade the web server as it requires higher skills and tougher to configure and debug, and most of all is expensive too. Besides, the insufficient knowledge of hardware components, performance, and scalability can hinder your growth potential. Hardware may become outdated quickly; and the web server administration is your responsibility.
The basic difference between a collocation and dedicated server is pertaining to the physical appearance. While the former provides an Internet connection to your server and allows you physical access to your own server, the latter does not allow you to have physical access to the server. The dedicated server is owned by the web host. You can customize the server as well as can rent the server but can have remote access only.
