Exercise 11 - On-Premises and CloudIn today’s technology, there’s been an increase in the development of cloud solutions, and two new terms are used a lot: on-premises and cloud. The main difference between them depends on where the organizations keep their hardware and software. In this exercise, you will learn about on-premises and cloud networks. Learning OutcomesAfter completing this exercise, you will be able to: Describe On-Premises and Cloud Networks Your DevicesThis exercise contains supporting materials for Cisco. On-Premises and CloudWhen designing a network, you will first need to decide on the environment that will be used - on-premise, cloud, or even a hybrid (combination of on-premise and cloud). This is a complex process, and there are a number of factors involved that could affect a customer’s decision. In an on-premise environment, everything will be in the datacentre and under your control. This means the company will have a server room where all networking devices will be in place. Also, all datacentre devices, like servers and storage devices, will be connected and placed here. All applications and services that are provided to the users are installed on these devices. In a cloud environment, everything is placed somewhere else. Cloud services are provided by a cloud provider. There are three models of cloud services: SaaS - Software as a Service PaaS - Platform as a Service IaaS - Infrastructure as a Service You can, for example, have servers and storage allocated in cloud provider rooms or you can use the provider's servers and storage to run applications and services. Two key differences between cloud and on-premise are the cost and level of ownership involved. Different cloud services have different levels of ownership. In the IaaS model, the customer is responsible for their applications and data, while the cloud provider is responsible for the customer’s servers, storage and networking. In the SaaS model, the cloud provider is responsible for everything, including applications and data. For smaller companies, cloud is more useful as you will be able to utilize the full functionality of cloud services at a reasonable price . Cloud hardware and software are usually available in a monthly or annual subscription package. These subscriptions cover training, support, and updates. Therefore, cloud services provide users with greater flexibility, efficiency and are cost-effective. Companies like AWS, Azure, and Google provide cloud computing services . On-premises services are usually used by large organizations. It is very expensive to use cloud services in big businesses. In an on-premise environment, the company will be responsible for training, support, and updates . On-premise applications offer complete ownership and control. They are presumed to be more reliable and secure. There are no screenshot items for this exercise. Download 1.21 Mb. Share with your friends:
