Cloud technology is a common word, for the delivery of hosted services, more than the internet, it is all over, while, same of cloud computing is accessing , and storing data and program over the internet. It’s just a metaphor for the internet. It is a process of delivering the elastic software services using the internet, it provides scalable software services.
Benefits of cloud technology
a) Pay per use – allow users to pay only resources.
c) Self-service provisioning
Models of cloud technology
a) Private – In this the services are delivered from a business. It’s preserving the organization, manage and protection general to local data centers.
b) Public–This is sold on-demand. In this, the third party delivers the cloud services more than the internet. Clients only pay for the CPU cycles, storage or bandwidth what they are consumed.
c) Hybrid- It is the combination of public and private cloud computing. It is cloud creates the scalable, automated and combined environment.
Cloud technology offers many cloud-based services
1. Iaas (infrastructure as a service)
2. Paas (platform as a service)
3. Saas (software as a service)
4. Utility services
5. Managed services
6. Mbaas(Mobile backend as a service)
1. Infrastructure as a service(Iaas)
Organizations make use of the unlimited storage, a capacity of the cloud infrastructure. It can increase and reduce in size their, storage space as needed without having to worry about dedicated servers on site.
Examples of Iaas (Cloud technology) : Virtual private servers (VPS), load balancers, network in and out, storages.
While,This service can provide a large storage to users.
Users can use the unlimited storage of the cloud infrastructure. They can extend their storage as needed. Therefore, we can use this service to maintain and upgrades the tools and database system etc.
As a result , networking services of Iaas (infrastructure as a service) are:
a) Operating system
b) Virtualisation process
c) Data center
d) Networking security and firewalls
e) Storage and services
2. Platform as a service (Paas)
Cloud technology can provide the service , the main function of this service is building the cloud applications and services. Its provide the platform for developing, such applications and services. They find various development tools, such as database management system, application servers, and business analytics.
The main advantage of this service is, there is no need to manage backups. Only one variation extra in Paas, that is database management system and development tools. Probably, the organization is responsible for upgrades of software developed. Therefore, a user can also host and access the PaaS services, in the cloud with their web browsers over the internet.
Hence, Companies can run their applications software, on the cloud technology service’s plan without having a worry, about maintaining hard drives and servers.
Examples– Website hosting, web servers, database, and software development tools etc.
3. Software as a service (Saas)
The applications are hosted in “the cloud” and, both individuals and organizations can use a wide range of tasks . Saas is an on-demand software service. Also,there are many functions of software as services are:
a) File Transfer
b) Custom Install
d) View Individual Data
e) Collect Data
4. Utility services
It is the process of providing a service through on-demand, pays per use method.
