 Cloud design

There is no single ideal cloud architecture or infrastructure. All clouds require operating systems, such as Linux® , but the cloud infrastructure can include multiple bare metal , virtualization, or container software systems that extract, pool, and share scalable resources on a network. That is why it is better to define clouds by what they do , and not by what they are made of . You can be sure that you created a cloud if you configured an IT system with the following characteristics:

Other computers can access it over a network.

Contains a repository of IT resources.

It can be quickly deployed and expanded.

You can design a private cloud on your own or use a pre-defined cloud infrastructure such as OpenStack® . There are thousands of cloud providers around the world, and these are some of the best known:

Building a hybrid cloud requires a certain level of portability, organization, and workload management. Application programming interfaces (APIs) and virtual private networks (VPNs) are the standard ways to create these connections. Many of the major cloud providers even offer customers a preconfigured VPN as part of their subscription packages:

Google Cloud offers Dedicated Interconnect

Amazon Web Services offers Direct Connect

Microsoft Azure offers ExpressRoute

OpenStack offers OpenStack Public Cloud Passport

Another way to create a hybrid cloud is to simply run the same operating system in all environments and design container- based cloud-native applications that are managed by a universal orchestration engine such as Kubernetes . The operating system extracts all the hardware, while the management platform extracts all the applications. In this way, you can deploy almost any application in virtually every environment without having to renew the application, retrain staff, divide management, or sacrifice security cloud administrator.

Infrastructure as a service (IaaS)

Infrastructure as a Service (IaaS) provides users with cloud resources, such as computing, networks, and cloud storage , through a network connection. The rise of big data , mobile apps, and the Internet of Things (IoT) has increased the number of IaaS data storage providers such as DropBox.
