2. IntroductionThis slideshow outlines the various types of web hosting available on the market. For each hosting platform the following slides highlight:featuresbenefitsdrawbacksIt is important to bear in mind what you actually need from yourhosting provider when you weigh these up. Broadly, the twoareas to consider are performance & uptime cost 3. Hosting ConsiderationsDepending on the type of hosting package in question, the otherfeatures to consider are: the ability to control and customise hardware and software ifthe site needs bespoke or non-standard configurations the access to bandwidth - high bandwidth connections allowlarge amounts of traffic to flow quickly to and from the webserver and so are more important for websites which experiencehigh traffic volumes (i.e., page requests) or need to display a lotof content the amount of disk space (i.e., storage) on offer which willdetermine how big the site can grow and how much content canbe stored the digital security of the platform, especially for sites that areobtaining or using sensitive data such as e-commerce sites. 4. Background to Data CentresData centres are purpose built facilities which are designed tohouse servers which meet these aims at affordable costs for theclients. They offer: complex security and safety systems o to ensure that the servers are not compromised whilst theyare running extensive systems in place to generate the optimal conditions o e.g., heat and humidity o for the servers to run smoothly and efficiently 5. Shared HostingThe shared in shared hosting refers to the fact that the web serverthat hosts the site is shared between numerous clients and theirwebsites. It is the typical entry-level option for small scale non-critical and non-sensitive (data) websites.Features: Client rents a portion of a server The shared server also hosts other clients websites 6. Shared HostingBenefits:Inexpensive in comparison to other hosting platformsSimple hosting platform for clients with limited hostingexpertisePhysical security of data center locationPhysical safety of data center locationDrawbacks:o Higher risk of security issues spreading from other websiteso Higher risk of software failures caused activities by other clientsetco Limited physical resources such as bandwidth and disk spaceo Limited scope for configuration of the software platform (operating system etc) 7. Virtual Dedicated ServersUsually shortened to VPS, this type of hosting still shares a singleserver across multiple sites/clients but each site has its ownoperating system partition and so it offers more control andsecurity whilst remaining cost effective.Features: Client rents a virtual partition on a server The shared server also hosts other clients websites on separatepartitions 8. Virtual Dedicated ServersBenefits:Inexpensive in comparison to other hosting platformsAllows greater customisation of each operating systemPhysical security of data center locationPhysical safety of data center locationDrawbacks:o Some risk of security issues spreading from other websiteso Some risk of software failures caused activities by other clientsetco Limited physical resources such as bandwidth and disk space 9. Dedicated HostingDedicated hosting is popular with larger business clients whereperformance and security are paramount and the budget is inplace to do pay for it, because it offers complete control, highsecurity and uncompromised physical resources.Features: Client rents an entire single server Web site has access to all physical resource and connectivity Often comes with managed hosting 10. Dedicated HostingBenefits:Scope for complete control over server configurationNo competition for bandwidth resourceNo competition for processor resourceAccess to entire servers disk spaceNo security threats from other sites/partitions on the serverDrawbacks:o Cost of renting entire servero Potential for wasted capacity if higher spec hardware is rentedthan the site requires 11. Co-locationSometimes referred to as Colocation or simply Colo, this form ofhosting allows clients to reap the benefits of a data centerlocation but still retain ownership of the hardware.Features: Client buys and owns server(s) Servers are housed in a data center Client rents space for servers 12. Co-locationBenefits:Physical security of data center locationPhysical safety of data center locationAccess to high bandwidth connectionsRetained value of the hardware as company assetsDrawbacks:o Initial cost of purchasing serverso Less scalability due to cost of replacing hardwareo Potential for wasted capacity if high spec hardware is purchasedto future-proof the platform 13. Cloud HostingCloud hosting essentially uses a large pool of physical hardware and resource to build virtualised hosting environments which are therefore not restricted to physical limitations. It can provide a solution for those who want a flexible platform where complete control and customisation is not a requirement.Features: Client rents virtual hosting resource Hardware resource taken from multiple servers Hosting resource (bandwidth, disk space etc) supplied ondemand 14. Cloud HostingBenefits:Not reliant on one server - less risk of failures/downtimeClients only pay for what they useSeamlessly scalable - extra virtual resource can be assigned asand when it is requiredDrawbacks:o Limitations on the ability to configure the platformo No scope for customising hardwareo Risk of security issues spreading from other websites 15. Managed HostingManaged hosting is a type of hosting where the features refer tothe support that the client receives rather than the type ofserver it comes with and therefore it can incorporate any type ofhosting/server set up such as shared or dedicated. A fullymanaged platform is effectively the deluxe package for clientswith larger budgets and a shortage of expertise in-house.Features: Expert support and advice Technicians available to make configuration changes Performance monitoring Usually a dedicated server 16. Managed HostingBenefits (depending on the type of support):Access to the expertise and knowledge of hosting providerRound the clock support in case of performance issues ordowntimeProactive and reactive support for changes in the web site orweb site usageHelp to effectively scale and configure platformDrawbacks:o Will tend to be expensive in comparison to self-managedpackages
