Satellite offers a fully managed set of core application services that run across cloud environments including IBM Cloud, on-premises and edge. The advancement of virtualization technology has made Cloud Computing an integral part of every industry. Large clouds, predominant today, often have functions distributed over multiple locations from central servers. And sometimes data residing in the cloud and possibly in a different country is an advantage. Public cloud facilitates access to IT resources on a "pay as you go" billing model. You need to test and develop application code. For example, hybrid cloud enables a company to keep sensitive data and mission critical legacy applications (which can’t easily be migrated to the cloud) on-premises while leveraging public cloud for SaaS applications, PaaS for rapid deployment of new applications, and IaaS for additional storage or compute capacity on demand. Its a general perception that public clouds are less secure and data in them can be accessed by anyone. All clouds require operating systems—like Linux® —but the infrastructure can include a variety of bare-metal, virtualization, or container software that abstract, pool, and share scalable resources across a network. In addition, providers have a multi-tenant architecture that enables users -- or tenants -- to share computing resources. Cloud security requires strong access management, encryption for data at rest, in transit, or in use, and excellent visibility to monitor, detect and manage cyberthreats. This type of storage exists on a remote cloud server and is accessible over the internet under a subscription-based utility billing method where the users pay only for the storage capacity being used. Cloud computing has transformed from a niche solution to the standard way of running IT in the enterprise. } The cloud provider also manages the underlying virtualization software. A public cloud is a type of cloud computing in which a third-party service provider makes computing resources—which can include anything from ready-to-use software applications, to individual virtual machines (VMs), to complete enterprise-grade infrastructures and development platforms—available to users over the public Internet.
