CLOUD TECHNOLOGIES
Cloud technology is one of the most popular technology in the internet era. which allows the entire world to work from any where. Before the implementation of cloud technologies the entire world was moving through the old physical server based development.
After founding the technology most of the development activities have adapted the technology. Which makes the development easier and cost effective. Instead of the physical systems and the physical servers , the world adapted the virtual systems and the virtual servers. which allows the world to move their services to clouds.
Advantages of using the cloud technologies.
Main advantage of implementing the cloud technology in to the project is flexibility of work. Just think about how the deployment was done before. Everybody needs to be in the office Infront of the server . if something happens to the physical server should be worried about the backup and the data lose. But now everything has changed. By sitting on the room using a user name and password it is able to deploy a build. that is the main advantage of the cloud technologies. Everything which you need to work for a product comes under a cloud. you don’t need to worry about the physical damage. Instead of that you can focus on your work . which will increase the productivity .
SaaS, PaaS, IaaS comes together in the cloud technologies . These three services gives you the complete solution to develop and maintain the product.
SaaS : Software as a service, which allows you to access the service through the internet by entering your unique username and password. dropbox is an example for SaaS
IaaS: Infrastructure as a service, Which allow yo to access the virtual machines and servers. The main advantage of the IaaS is the Scalability. When we need to scale out system or the service , Just a click is enough to do the big task.
Disadvantages of Cloud technologies
Still there is a question rise , Is our data is secured in the cloud. That is the Main disadvantage of cloud technology. There is a possibility of data leak. An expert who could hack the cloud is enough to destroy the entire trust on the cloud.
Types of cloud
Public cloud : Which runs under the public internet. AWS is an example of public cloud
Private cloud: which runs under a private network. The login and the authentication is done by the private network firewall.
Hybrid cloud: Both the combination of public cloud and private cloud is known as hybrid cloud.
Key values of cloud technologies
1.Scalability : Its easy to scale the size of the requirement in a single click.
2.Maintainability : Easy to maintain the server and the virtual machines through internet.
3.Pay money for usage only : pay for your needs only. If you need 10 Gb of space need to pay only for 10 Gb . No need to buy a 100 Gb for the future. Instead you have the option to scale it . So when the requirement comes you can scale it. Until The lesser space is enough for you. It save your money.
4.Migration : Easy migration from cloud to cloud technologies.
Conclusion
Here it concludes that the cloud technologies are the future of information technology. Physical work places will be replaced in the future with cloud technologies completely.
