Internet can be said to be the most revolutionary invention till date which connected the whole world, in an abstract way. As a result of the speedy evolution of internet technology, the world witnessed an IT boom. And today, everything is present there on the cloud! Cloud is the technology which uses virtualization platform from distributed servers or computers that ensures no impact on data security. Because it is connected to multiple servers, failure of one server will not have any impact on the data as rest of the them in the cluster will manage the failover. Cloud allows wide data accessibility, data can be accessed from anywhere anytime. There is a wide range of Cloud solutions offered by data center services providers.
Based on deployment technology, there are three types of Cloud:
Public Cloud vs. Private Cloud vs. Hybrid Cloud
|Public Cloud Hosting||Private Cloud Hosting||Hybrid Cloud Hosting|
|The network is opened for public use||Single-tenant environment, operated for one client||Combination of both private and public cloud|
|Access is through internet||Resources are managed internally or even outsourced in private cloud hosting||It offers the advantages of both models of cloud deployment-private and public|
|Negligible fee||Huge Capital investment||Payment needs to be done for extra resources used|
|Security is only compromised if web activities are carried on non-trusted networks, else it’s secured model||Resources are not shared with anyone else, so it’s greatly secured.||It’s secured but needs to comply with applications used by the enterprise|
|In relation to the negligible investments made, fair deal of ROI is earned||Dedicated computing, storage and networking definitely bring High ROI for businesses||High ROI|
Moreover, following are the three important layers of cloud, distinguished based on the form of services they offer.
SaaS: Short for Software-as-a-service, it is the most popular cloud service model. Applications like CRM enables unified communications in SaaS cloud model. The users do not need to install the software applications on the computer due to which there is lesser need for support and maintenance. The billing and payment is based on pay-per-use system, making it a cost-efficient cloud solution.
PaaS: Platform-as-a-service, is all about cloud computing platform that allows developers to use it for managing their IT applications with fully control on the configuration settings like OS, database, web services, programming language etc. to host applications.
IaaS: Infrastructure-as-a-service, is related to offering virtualized computing resources on web. In IaaS model, the cloud provider will manage and host the infrastructure including storage, hardware etc. on behalf of the users.
Choosing the right cloud technology decides your enterprise’s business operations. Whether to go for (Private cloud hosting or public cloud hosting or hybrid cloud hosting) completely depends upon your scale of operations, IT budget, security needs and other such IT infrastructure and resource factors.
