Cloud Hosting for Beginners
Cloud hosting is the buzzword of hosting industry today, if you are from the industry, it is very likely that you will come across this term umpteenth times in a day. But what exactly is cloud hosting and what makes it so popular? Let us try to find the answer.
Cloud hosting is a hosting services that relies on virtual servers and that is the biggest advantage of this hosting. By virtual servers, we mean, that instead of being hosted on a physical hardware/servers with limited capacity, the cloud hosting is hosted on many interconnected machines that are capable of sharing their computing resources whenever needed and perform as a single machine. In this model multiple servers are interconnected and the hosting services derive their computing resources, memory, data storage capacity, etc. using the required portion out of collective capacity of multiple servers.
The best part of cloud hosting is that you get the constant, uninterrupted performance even during the instances of very heavy traffic, high data or other similar situations. For example if on a fine day due to a surge in data your website need more hard disk space than offered by a single server. In this scenario 2 or more connected virtual servers can combine their hard disk capacity to store your data acting as a single machine. The same model of sharing is true with other computing resources too. One advantage here is that your website is flexible to use as less or as much energy as required and you are charged according to usage.
Cloud Hosting is further divided into 3 categories:
As the name suggests the public cloud is hosted on a very large scale by enterprises (Mostly Big Players) catering services to the general public or businesses. The main benefit of this model is low cost due to large volume. But the client does not have the direct control on hosting services nor is he able to monitor the infrastructure or machines. The common resources are shared among all the users and thus each user have limited configuration. Public sharing can also pose security threats to the data.
• Low Cost
• No Hardware Purchase necessary
• Maintenance, Deployment and other services are taken care of by the service provider
• Limited Configuration
• Limited security
• High variations in resource availability
Private cloud is a dedicated hosting for a particular organization and is not shared with any other organization or individual. It can either be hosted in the premises or off-premises. The maintenance services can be looked after by dedicated staff or outsourced to a third party. But in either option, the data is completely secured and the owners have the full control as opposed to public hosting.
• Complete administration Control
• 100% Data Security
• Complete resource availability for better performance
• High Cost
• Maintenance and management of servers is company’s responsibility
• Cost of Hardware and deployment to be borne by the organization, needs higher level of engagement
A perfect balance of the above 2 models, hybrid cloud hosting combines the best features of both public and private clouds. In this model of hosting you can partition the resources in 2 categories. The vital internal data of the company can be hosted on the private cloud while the data of general nature can be hosted on the public cloud hosting. In short it offers you the flexibility of moving between public and private hosting according to the need.
• Enhanced security for vital data
• Flexibility to augment the resources for general data
• Cheaper rates than dedicated hosting while offering the security for your internal data
• Vital company data is supported and managed by internal IT infrastructure
• The process data transferred between public and private cloud is always prone to the security risks
• A proper bridge between private and public cloud hosing needs makes the process of networking quite complex
