In today’s article we analyze the first type of cloud: the Public Cloud.
Let’s start with a definition. A public cloud is one based on the standard cloud computing model, in which a service provider makes resources (VPS, IaaS, PaaS or SaaS) available to the public over the Internet. Public cloud services may be free or offered on a pay-per-usage model.
Cloud Computing: Public Cloud
Type of Cloud computing: Public Cloud
As you can see the accent is on where the data (VPS, Infrastructure, Platform or Service) is stored. In case of a public cloud the resources are stored on the service provider’s servers and storage. The customers will be able to use and reach them through the Internet. The services provided are offered to multiple clients who all share the same hardware. Some of the most common real world examples of public cloud services include services like cloud based server hosting, storage services, webmail and online office applications.
One of the main benefits that comes with using public cloud services is near unlimited scalability. The resources are offered ‘on demand’ so any changes in activity level can be handled very easily.
The vast network of servers, storage and datacenters involved in public cloud services means that it can benefit from greater reliability. Even if one datacenter fails entirely, the network simply redistributes the load among the remaining ones making it highly unlikely that the public cloud would ever fail.
The benefits of the Public Cloud:
- Easy scalability
- Cost effectiveness
- Increased reliability
The disadvantages of the Public Cloud:
- Data location
As a conclusion we can say that the Public Cloud is ideal for you if you are not storing sensitive data and you don’t have the need to constantly control, secure and locate your data. In this scenario you depend completely on your provider. If for any reason he looses part of your data and you don’t have a backup of it out of the Public Cloud you are using, there is no way you can get it back or try to restore it, because you do not have access to the physical servers and storages.
How important is the service, data or infrastructure you are hosting on the Public Cloud?
Do you know what SLA your provider is offering you and what are the limits of its responsibilities?
These are questions you should ask yourself before you start using this type of cloud computing. In this scenario, more than in any of the following that we will talk about, it is absolutely important to trust the provider.
