What has been discussed?
Now, you know the basic info regarding cloud computing and its basic structures. You see, it’s quite similar to premium hosting plans by Fatality Servers, only that it has tons of useful differences.
Here we will traverse through the various types of cloud computing options that are available. As discussed in the earlier chapter, the cloud structure should now be clear. This classification mainly aims at implementation of cloud services. Based on this the cloud systems are classified as:
- The public Cloud
- The private Cloud
- The hybrid Cloud
- The community Cloud
- The combined Cloud
So in this chapter we will traverse through each of the available options on each classification.
The PUBLIC CLOUD
The publicity on cloud is due to the public cloud domains that are available, starting from Google docs to the windows Azure services platform. You will find public cloud ruling and redefining the way we compute. When a public cloud is defined the resources and applications are provided by the vendor firm and the services are made available either free or pay per use plan. The plus part on public cloud is the scalability it provides. You can be using most of the resources or upgrading resources as per your requirement or your project requirements.
No shortcomings to the public cloud when a generic user is in consideration as they do get what they sign up for and the services are mostly flawless. Ignoring the error percentage based on the successful ones.
The cons for public cloud is the missing feature to be able to customize your software or addition of modules on to the software in use, most providers do keep the popular extensions or add-ons for the services but still there is the missing customization option that is regarded as a trouble to public cloud domain.
The PRIVATE CLOUD
Douglas Parkhill was the first to introduce the idea of a private cloud. Private cloud or an internal cloud is usually the neologisms where an organization maintains a cloud infrastructure over a private or internal network. Usually the private cloud is regarded elite and is more costly than what public cloud offers. This is usually used on high profile projects or government projects which require ultimate security and performance.
The HYBRID CLOUD
Hybrid clouds are new offerings. The idea is to provide cloud computing using dedicated servers, this draws a median between the public and private cloud. Vendors like HP, IBM, Oracle and VMware has now launched products which offers this technology and helps to manage the services. There are still concerns raised over performance, security and privacy of the data that are kept on hybrid clouds. But for the instance this is regarded as the best solution for people who wish to keep out of public cloud systems. The hybrid cloud also puts forward excellent storage solutions which hold data using both public and private clouds. The storage system is manageable using web interface, hence increasing the option of scalability of storage systems with increasing demand.
Web apps are deployed on to hybrid system considering them to be working on both dedicated servers and public cloud. This does help in maintaining the data over cloud and also keeping this restricted to a specific organization and avoiding public domain to be used for sharing sensitive data.
We will be discussing more on hybrid cloud and VMware products shortly in this book.
The COMMUNITY CLOUD
This involves various organizations coming in together to provide cloud services. Since this involves multiple organizations in effect they do help in maintaining a vast option for computing. Also the costs are cut down as each individual organization has to maintain a small or a share of resources for the whole product. The added feature is the lesser participation of public, there will be lesser users compared to the public cloud domains. Also they are interconnected over a secure channel which adds in more security. There are various products that run on this technology and the famous one is the Google Government cloud offering.
The COMBINED CLOUD
Combined clouds are deployed by various providers or provider which does offer options like PCI compliance. They will have tuned applications that will help you cover the PCI guidelines and get clear of the PCI checks. There are different combined clouds available for various requirements that combine features of each individual module to get you work efficiently.
Now that we are aware of various types of cloud, I will take this opportunity to describe few terms that you will be learning further as we move on.
The CLOUD ENGINEERING
The technical definition of cloud engineering goes as ” A systematic, disciplined, quantifiable and inter disciplinary approach and ideation, conceptualization, development, operation and maintenance of cloud computing is known as cloud engineering”.
A cloud engineering team is mostly dedicated in deploying and maintenance of new cloud applications and features.
The CLOUD STORAGE
This is another concept in use with cloud infrastructure; the idea is to store data on multiple servers (virtual servers) hosted on third party storage platforms. The plus about this idea is that data is spread over high count of servers which adds in to security and also helps in recovery in case of a crash on the server.
Another novel concept by Kevin Kelly, where the inter cloud was defined which basically thinks of combining various service providers of public cloud into one single cloud thereby providing endless possibilities to clients and a high set of resources for each user.
As we complete this chapter, the above descriptions was a brief overview on the cloud types in use. We will go further and discuss the pros and cons of cloud computing in coming chapters.
