In computing, a client can be a web browser or desktop application that a person interacts with to make requests to computer servers. A server can be services, such as Amazon Elastic Compute Cloud (Amazon EC2) – a type of virtual server.
The three cloud computing deployment models are cloud-based, on-premises, and hybrid.
Cloud-based deployment model, you can migrate existing applications to the cloud, or you can design and build new applications in the cloud. You can build those applications on low-level infrastructure that requires your IT staff to manage them. Alternatively, you can build them using higher-level services that reduce the management, architecting, and scaling requirements of the core infrastructure.
On-premises deployment is also known as a private cloud deployment. In this model, resources are deployed on premises by using virtualization and resource management tools.
Hybrid deployment, cloud-based resources are connected to on-premises infrastructure. You might want to use this approach in a number of situations. For example, you have legacy applications that are better maintained on premises, or government regulations require your business to keep certain records on premises.
Trade upfront expense for variable expense
Upfront expense refers to data centers, physical servers, and other resources that you would need to invest in before using them. Variable expense means you only pay for computing resources you consume instead of investing heavily in data centers and servers before you know how you’re going to use them.
By taking a cloud computing approach that offers the benefit of variable expense, companies can implement innovative solutions while saving on costs.
Stop spending money to run and maintain data centers
Computing in data centers often requires you to spend more money and time managing infrastructure and servers.
A benefit of cloud computing is the ability to focus less on these tasks and more on your applications and customers.
Stop guessing capacity
