Key Characteristics of Cloud Computing

Most beneficial characteristics of cloud computing are:

- Speed and Agility λΉ λ₯΄κ³ 민첩ν¨
Cloud resources are provisioned with a few clicks, saving time and providing agility.

- Cost λΉμ©
By reducing the up-front cost to set up the infrastructure, it allows users to focus on applications supporting the business processes. Another beneficial feature of cloud providers is a cost estimator, which assists users in better resource planning.

- Easy Access to Resources μμμΌλ‘μ μ¬μ΄ μ κ·Ό
Users can access the cloud services from any place and device, as long as there is connectivity to the cloud service provider.

All the lights-on maintenance work maintenance work to keep resources up, running, and up-to-date is offloaded onto the provider, and it is no longer the user's concern.

λνΈμ±
Multiple users sharing the same pool of resources, which helps to drive down the costs incurred by each user.

Resources can be hosted in redundant data center locations, to provide increased reliability, resiliency, and high-availability.

- Scalability and Elasticity νμ₯μ± λ° νλ ₯μ±
Self-serviced provisioning coupled with functionality that enables cloud resources to scale upwards (increase in size) and outwards (replication) dynamically to meet clients' demand or to maintain optimal levels of resources' utilization. Downward (size decrease) and inward scaling is also automated.
