Cloud computing brings a lot of benefits that contribute to IT's economy. Some of the most important benefits can be described as follows:
- Small start-up costs: Most cloud-based services are pay-per-use. The services available are considered as rental equipment that are paid for depending on how much equipment is needed, at what time, and with what services it is leased. This renting of infrastructure allows organizations to keep their IT costs low and capital investment virtually zero.
- More effective use of resources: System administrators are mostly concerned about the procurement of hardware. Using cloud-computing architecture allows better and more efficient management of resources, as system admins can access applications only when they are needed and can then stop using them.
- Reducing execution time and response time: Applications that use clouds to perform many different cloud-computing tasks allow them to run on a variety of different servers. For example, performance can be enabled on 1,000 servers and thus speed up the workload.
Processing in this way can be done in one-thousandth of the time that would be needed by one server.
It is important to note that cloud-computing servers are often (but not always) used together with virtualization technologies. Organizations using information technologies understand that virtualization enables them to swiftly and easily copy the existing environments, sometimes including multiple virtual machines to support the testing, development, and storage of activities.
The possibilities that cloud computing can offer to users can be quick and elastic
initiated, in some cases, and automatic, in order to, if necessary, proportionally increase or decrease opportunities when they are no longer needed.
Systems that use cloud computing are automatically checked and optimized for the use of resources.
The use of resources is optimized by the impact on measurement capability abstractions appropriate to the required type of service (for example, data storage, bandwidth, or active accounts).
Also, the use of resources can also be monitored and verified. Reports can be run by providing a transparent insight to service providers' users.
For software as a service (SaaS), the service provider allocates, configures, maintains, and updates software applications on the cloud structure so that the services are equipped as expected.
For platform as a service (PaaS), the service provider manages the platform infrastructure and the cloud software used for platform components, such as databases.
So from this, we can conclude that the PaaS service provider usually develops, implements, and manages PaaS types of clouds. The IaaS service provider has control over physical hardware, and with the cloud software that makes the services of this infrastructure possible, such as physical servers, network equipment, or storage devices. Therefore, from the activities of the provider, we can describe the service as development, management, security, and privacy of clouds.
Let's understand each in detail.
