Public Cloud
Need help with cloud migration or public cloud deployment? We offer access to all of the major public cloud providers – AWS, Microsoft Azure, Google Cloud and IBM cloud. We also offer multi-cloud solutions and cloud optimization. Call 877-708-8900 to speak with an expert.
A public cloud is one based on the standard cloud computing model, in which a service provider makes resources, such as virtual machines (VMs), applications or storage, available to the general public over the internet. Public cloud services may be free or offered on a pay-per-usage model.
Public cloud is a fully virtualized environment. In addition, providers have a multi-tenant architecture that enables users — or tenants — to share computing resources. Each tenant’s data in the public cloud, however, remains isolated from other tenants. Public cloud also relies on high-bandwidth network connectivity to rapidly transmit data.
Public cloud storage is typically redundant, using multiple data centers and careful replication of file versions. This characteristic has given it a reputation for resiliency.
Benefits of Public Cloud
Utility Pricing Model
One of the most attractive benefits of public cloud computing is that you can pay for your computing by the hour. If you only need a test server to run a 1 hour regression test, you can spin up the server, run your test, and turn down the server for less than $0.10. AWS even sells compute cycles at spot demand prices through an auction process.
API Access
Many public cloud hosts provide APIs (albeit proprietary) which allow users to programmatically spin up and kill servers through API access. These can be very beneficial for systems that need to spin up a massive number of servers such as research and test environments.
Configure and Pay Online
As opposed to a private cloud where the entire infrastructure is designed around a client’s specific requirements, the public cloud can be purchased online, configured and deployed, in most cases, automatically through the provider’s website.
