3. What are the different deployment models?
Answer: Cloud computing supports several deployment models, each has its own services and operation to a cloud environment. A larger organization uses a private cloud where small businesses utilize the public cloud, below are some of the deployment models:
1.Private Cloud: It is provided for a single organization having multiple business units. Private cloud is owned, managed and operated by the organization. It may reside in on or off-premises. Organizations opt for private cloud for sensitive and critical information as it provides security, reliability, service and it has the ability to scale.
2.Community Cloud: It is provided to be accessible by a group of an organization as it shares infrastructure between which belongs to a particular community, i.e. bank and trading firm. It can be managed and operated by the company, a third-party, or a combination. It may reside either on-premises or in a remote data center and it can be hosted internally or externally.
3.Public Cloud: Public cloud infrastructure is open for use by the public. It is more secure than accessing information via the internet. It is managed and operated by a government organization or business and it exists on the cloud provider.
The public cloud provides functions like collaboration, CRM, Storage, and social networking.
4.Hybrid Cloud: It is a combination of two or more different cloud deployment model that remains unique entities and they are bound tоgеthеr bу ѕtаndаrdizеd or proprietary tесhnоlоgу thаt еnаblеѕ data аnd application роrtаbilitу (е.g. сlоud bursting for load-balancing between clouds).

Answer: Scalability is a characteristic of cloud computing through which increasing workload can be handled by increasing in proportion the amount of resource capacity. It allows the architecture to provide on-demand resources if the requirement is being raised by the traffic. Whereas, elasticity is being one of the characteristic provide the concept of commissioning and decommissioning of a large amount of resource capacity dynamically. It is measured by the speed by which the resources are coming on demand and the usage of the resources.
11. What is cloud computing?
Answer: cloud computing is computing which is completely based on the Internet. It can also be defined as the next stage in the evolution of the Internet. Cloud computing uses the cloud (Internet) that provides the way to deliver the services whenever and wherever the user of the cloud needs. Companies use cloud computing to fulfill the needs of their customers, partners, and providers. Cloud computing includes vendors, partners, and business leaders as the three major contributors. The vendors are the one who provides applications and their related technology, infrastructure, hardware, and integration.
The partners are those who offer cloud services demand and provide support service to the customers. The business leaders are the ones who use or evaluate the cloud service provided by the partners. Cloud computing enables companies to treat their resources as a pool and not as independent resources.
