A cloud system which can also be called "cloud computing system" refers to the computing components– infrastructure, hardware, software, that enable the delivery of cloud computing services such as infrastructure as a service(IaaS), software as a service(SaaS) and platform as a service(PaaS).
In simpler terms, cloud system is sharing resources and information through a network–the internet. The cloud is a virtual space that connects users from all over the planet, sharing information through satellite networks. The cloud system can also be called utility computing because consumer usage is Meyers and billed in a similar manner as to water and electricity.
How does cloud system work
The information and data can be stored through physical and virtual servers, which are controlled and maintained by the cloud computing provider. As a cloud computing user you are able to access your stored information on the cloud through an internet connection. When you use the cloud storage, you no longer need to store information on your own hard drive, you will be able to access your information from any location and download it into any device– smartphones , laptops, tablets etc, You can also edit files, such as PowerPoint presentations, word documents making it easier for you to work even while away from the office.
There are different types of cloud computing storage for different needs. Some attend to the needs of individuals who want to store videos, photos, and documents. While some cater to companies who need extensive platforms to develop their programs. As an individual user, you get about 5GB with icloud as an initial amount for free. But if you need an additional storage, you will have to pay a fee. Fees are monthly or yearly rates, Depending on the server you are using, the price may differ.
Types of cloud system
Cloud computing can be described in two ways. It can either be based on the service the cloud is offering or deployment model.
1. Based on the service
Based on the service the cloud is offering, the cloud system or computing can be classified into four groups.
Infrastructure as a Service( IaaS) is one of the most current cloud service because it offers data storage disks and virtual servers. Examples of Infrastructure as a Service (IaaS) companies are Amazon, Rackspace, Flexiscale.
The model known as platform as a Service(PaaS) offers a development platform, this includes operating system, executive environment, database, web server and programming language. Examples of platform as a Service is the Google app engine.
Software as a Service (SaaS), means that users can access various software applications on a pay per use basis. As opposed to buying licensed programs, often very expensive. Examples of such services include widely used GMail, or Google Docs.
Storage, Database, Information, Process, Application, Integration, Security, Management, Testing as a Service.
2. Development Model
Based on a deployment model, cloud computing can be classified as:
Public cloud is the whole infrastructure located on the premises of a cloud computing company that offers cloud services. The location is separate from the customer and the customer has no physical control over infrastructure.
As public clouds use shared resources, they do excel mostly in performance, but are also most vulnerable to various attacks.
Private cloud uses a dedicated private hardware, the private cloud uses a cloud infrastructure solely by one customer or organisation. It is not shared with other people and is remotely located. You can opt choosing an on premise private cloud, it is more expensive and you will have physical control over the network or infrastructure. The security level and control level are the highest while using a private cloud.
With the hybrid cloud, you can use both the public and private clouds, depending on their purposes. Hence the name "hybrid".an example of this, is a public cloud can be used to interact with customers while keeping their data secured through a private cloud.
The community cloud is an infrastructure shared between organisations, a community cloud can be owbed by the government of a country, for example. Community clouds can be located both on and off the premises.
Is my data safe?
Bow know all about the cloud system, you may be wondering if your data is safe.
The issues regarding cloud security are complex and fall into two broad categories:
The cloud computing security offers a range of security options to make sure your data is encrypted and safely stored. Cloud storage providers and enterprises share responsibility for cloud storage security. Cloud storage providers implement baseline protections for their platforms and the data they process, such as authentication, access control, and encryption. Most enterprises supplement these protections with added security measures of their own to ensure cloud data protection and tighten access to sensitive information in the cloud.
Cloud storage risks
Cloud security is immensely tight but that doesn't mean it is infallible. Cybercriminals can get into those files, whether by guessing security questions or bypassing passwords. The bigger risk with cloud storage is privacy. Even if data isn’t stolen or published, it can still be viewed. Governments can legally request information stored in the cloud, and it’s up to the cloud services provider to deny access. Tens of thousands of requests for user data are sent to Google, Microsoft, and other businesses each year by government agencies. A large percentage of the time, these companies hand over at least some kind of data, even if it’s not the content in full.
However, there are some controls in place to reduce attacks ,strengthen the system against incidents and reduce the consequences of an incident.
In conclusion, no system is a hundred percent safe, but cloud infrastructure has almost attained this goal. Data is safe in the cloud.
