What Is Cloud Computing?
Cloud Computing is a big shift from the traditional way of busines think about IT sector. cloud computing eliminates the capital expense of buying hardware and software and setting up and running on site datacenters. Cloud Hosting is the use of software and hardware to deliver a service over a network with users can files and can useapplications from any device that can access the internet. An example of a Cloud Computing is Google’s Gmail.
BENEFITS OF CLOUD COMPUTING:-
The benfits of cloud ccomputing services include the ability to scale elastically. that means delivering the right amount of IT resouces for example computer power , storage ,bandwidth ,geographic location etc.The biggest cloud computing services run on a worldwide network of secure datameters which are regularly upgraded to the latest genertion of fastand efficient computing hardware. Most cloud computing services are provided self service and on demand so even vast amunts of computing resources can be provisioned in minutes.
Different Types Of Cloud Computing Services :-
We know very well that cloud computing has changed over tie it has been divided into three broad categories mainly:- infrastructer as a service categories,platform as a service andsoftware as a service.
SAAS:- Asotware distribution model in whicha third party provider hosts applications and makes themavailable to customers over the internet.
PAAS:- A model in which a third party provider hosts application developement platforms and tools on its own infrastructer and makes them available to customers over the internet.
LAAS:- A model in which a third party provider hosts servers, storage and other virtualized compute resources and makes them available to customers over the internet.
Cloud Computing Security:-
Cloud computing security adresses both logical and physical security issues across all the different service models of software,platform and infrastructure. cloud securit achitecture is effective only if the correct defensive implementations are in the place. these control are put in in place to safeguard any weaknesses in the system and reduce the effect of an attack.The Cloud Security Alliance, a nonprofit of industry specialists,has developed a pool of guidelines and fameworks for implementing and enforcing security within a cloud operating environment.
Cloud Computing Security Features:-
When a user searches for a cloud service provider then he or she needs to make sure that it must have these fetures in clud computing security.
All IT security compliance standars must involve the buisnesses to have a means that which can track and record there all type of intrusion attempts.there are some cloud providers who offer IDS monitoring service and update the security rules for their firewells in order to counter the threat signals and malicious IP adresses and which are detetcted for all cloud user.
Many usersthink are my files safe in the cloud? while no storage solution is 100% safe but cloud storage providers can you offer good deal and safer deal and more accessible place for companies to store data than traditional computing methods.
The cloud is not a fluffy white mass up of tinny water droplets which is floating in cyberworld. the cloud is not impacted by weather changes like barometric pressure.While having a strong perimeter firewell can block external attacks ,internal attacks and external attacks are still a major threat.
The physical hardware used to run a cloud environment represents one last opportnity for industries and hackers spies to steal your most importat data.hackers should never have this oppotunity to hack your personal data.
Private Cloud And Public Cloud :-
public clouds are the most commonway of searching cloud computing.in a pubic cloud you share the same software, storage,hardware and network devices with other organisations or cloud tenats.you acess services and manage any account using a web browser.
public cloud deployments are frequently used to provide web based email,storge and personal data etc.
Some advantages of public cloud :-
your sevice provider provides all the maintenance and service.
no need to purchase software or hardware and you pay only for the service you use.
a vast networkof servers ensures against failure.
What Is a Private Cloud:-
A private cloud is one based on the standard cloud computing featue. In which a service provider makes rearrange such as virtual machines 3d animations available to the general public over the internet. public cloud services may be free or offere on a pay per usage model.
the private cloud can be physically located at your organisation onsite datacenter or it can be hosted by a third party service provider.A private cloud can make it easier for an organisation to customise its reources to meet specific.
Advantages of private clouds:-
More flexiblity:- your organisation can customise its cloud environment to meet specific business need and opportunity to get something new in this feature.
private clouds still afford the scalablity and efficiency of a public cloud.
resources are not shared with others, so higher levels of control and secuity are possible to archieve.
