When your site is becoming popular and there is constant growth in the number of visitors, you might want to consider a stronger infrastructure for processing all these requests.
Cloud computing as an IT solution represents dynamically scalable and mostly virtualized resources that are offered as a service over the internet.
Cloud computing can be divided into three different models: public, hybrid, and private. While the three models have common traits, they also have different key features that might make one model a better choice to meet your business’ IT needs than another.
Let’s take a deeper look into these three models in an effort to determine what the best model is depending on your individual needs.
The private cloud is exactly what it sounds like – a privately built and operated cloud for just one company. They are more likely to be deployed by large enterprises than small companies, naturally. Pure private clouds are built and managed on the company’s network by their own IT staff and they require a high degree of expertise in technologies such as virtualization. These kinds of services are far more expensive than public clouds and take more time to get up and running, but they do offer more privacy, greater control over data, and better security.
Enterprises that want to take full advantage of existing IT infrastructure investments often start with an internal cloud. It applies the concept of cloud computing (on-demand resources, pay-as-you-go pricing, and the appearance of infinite scalability) to resources entirely owned by that company. If your business has complex legal requirements with physical controls of data, physical access to sensitive data, enhanced logging or secure access to data using keys or tokens, this is the right cloud model for you. For example, banks will always decide to go with private cloud solutions because of the sensitivity of the data they are working with on a regular basis.
As far as external or public clouds are concerned, the cloud-based service is hosted, managed, and maintained on the cloud provider’s network. Each company gets its own, contained instance of IT service and resources that are accessed through web browsers or through APIs, and offer nearly unlimited capacities on demand at pay-per-use pricing, but with limited customer control. One of the main characteristics of a public cloud is that it is considered multi-tenant, because more than one company can access it.
That is the key reason why some companies have concerns about security and privacy. At the same time, public cloud-based services are flexible, cost-effective, and convenient for many small companies. This model has the ability to support multiple offices and a great number of remote users. Public clouds can often offer greater availability and access to newer technologies than small companies can afford on their own networks. So if your business needs to replace a service or application that you currently run on-site and you are approaching End of Life (EOL) status, a public cloud will give you the infrastructure you need to move forward.
A hybrid cloud combines aspects of public and private clouds with different deployment models. For large companies, a hybrid cloud might include a private cloud that inter operates with a public cloud. For small companies, a hybrid cloud deployment is more likely to be a virtual or hosted private cloud, which gives you access to dedicated resources hosted by a service provider in a public cloud. This hybrid cloud model gives small companies tighter security than a public cloud, but it also offers more flexibility at lower costs than a pure private cloud. This can be a safe and reassuring way for small companies to ease into cloud computing, because they can choose which applications and data are accessible via the cloud.
Times when one computer was enough to process one service are all but gone, and today’s business models demand more resources and much stronger infrastructure than was the case just a few years ago. Cloud services can support your company and provide a continuity of business with automatic redundancy built into everything. Business can benefit from this service by lower costs for IT infrastructure, maintenance and monitoring. And the greatest advantage is that you can access your work from any device, anywhere and at any time.
