What is Cloud Computing in simple terms?
Do you sometimes think that how does cloud computing work? The cloud, as the name implies, is a kind of gigantic computer memory that hangs over our heads and can be accessed from anywhere.
The idea is to no longer need to be physically in one place to view working documents or holiday pictures. The cloud, everyone does without knowing it. Your email is the cloud. Emails are stored on a server and you copy them to your computer or smartphone for viewing.
Today, it goes further with even more services for individuals and businesses. It is quite abstract but it becomes more concrete soon as we put names on it. For example: OneDrive, iCloud, Google Drive, Dropbox, Orange, SFR or Hubic etc……
Advantages of Could Computing :
Every technology has some advantages and disadvantages. Below are some of the pros and cons of the cloud computing:
- updates and scalability : no need to update all the posts to add new features, just update the network application and all users benefit from new features and corrections. This results in a greater coherence of the working methodology and the documents produced by all the contributors of the organization.
- pooling resources : each user can contribute to enriching the data and experiences of the whole if collaborative tools are put in place. This advantage facilitates knowledge management in companies.
- security : if the documents are no longer present locally (and the user does not save his login credentials on his computer) it avoids the problem of lost or hacked computer and confidential documents lost in nature.
- computing power : the remote system on a network of servers offers a much better computing efficiency than a single station. This feature is developed in the fields of compression or video effects application, more broadly in the video sharing (Youtube etc.) but also in the online game (still in the test state for the big one). public, the bottleneck being the bandwidth of the user). This field is however really interesting in the context of application requiring significant computing power for mobile use.
- mobility : the user can at any time and from any device connect to its applications and workflow. It can access it from any type of device provided that it has a browser.
Disadvantages of Could Computing:
- security : the cloud platform, if it is external (not installed on the internal network or with an external opening) must be sufficiently secure to avoid the risk of intrusion, theft of data by hacking. The other risk is that a user forgets to log out of a device accessible by members outside the organization.In this case, it is necessary to provide for an automatic logout in the event of non-activity of the account and to segment the user rights so that they can only access the data of the projects in which they are involved. More generally, a confidentiality clause and trust in its staff are essential for the data to not leak on a voluntary basis.
- connection : this is the other bottleneck. If the user does not have an internet connection, or an insufficient connection, he will not be able to access his working platform.The idea in this case is to allow work on a local application that then synchronizes the data with the server as soon as the user has access to the network again. The problem of local data security arises again.
The different models of cloud:
Infrastructure as a service (IaaS) is the first cloud model, where:
- the company maintains: applications, runtimes, SOA (Service Oriented Architecture: Service Oriented Architecture) integration, databases, server software;
- the cloud provider maintains: virtualization, server hardware, storage, networks.
Platform as a service (Paas) is the second cloud model, where:
- the company only maintains applications;
- the cloud provider maintains: runtimes, SOA integration, databases, server software, virtualization, server hardware, storage, networks.
Software as a service (SaaS) is the ultimate cloud model, where the cloud provider maintains: applications, runtimes, SOA integration, databases, server software, virtualization, server hardware, storage, networks.
SaaS, often associated with “cloud computing” can be seen as an economic model of application consumption: these are consumed and paid on demand (per user per minute of use for example) and no longer acquired by the user. purchase of licenses. SaaS can therefore be based on a cloud computing infrastructure.
It is important for businesses to keep themselves updated with the latest technologies to remain the winners. But the technologies always come with some limitations or consequences which must be mitigated. Similar way the cloud computing has also its own benefits and limitations. We hope the above discussion about the pros and cons of the cloud computing were useful to you.
