Welcome to our new blog series, The Cloud Helpers. This series will focus on cloud computing topics and help you understand how the cloud can impact your business today and in the future. Out last post focused on private clouds. This week we will address another form of cloud computing, public clouds.
What is a Public Cloud?
Generally the most recognizable model of cloud computing to many consumers is the public cloud model, under which cloud services are provided in a virtualized environment, constructed using pooled shared physical resources, and accessible over a public network such as the internet.
A Public Cloud is one that’s based on the standard cloud computing model where services, applications and storage are made available to users over the Internet ‘as a service’ – typically on a Pay Per Use model. Public Clouds are appealing to many businesses as they reduce complexity and lead times, because the underlying architecture is fixed, there is less scope for customization for security and performance.
There are many types of Public Cloud, the most common being Infrastructure as a service (IaaS), Platform as a service (PaaS), Software as a service (SaaS) and Desktop as a service (DaaS) platforms .The economies of scale afforded by Public Cloud computing are what make this technology highly attractive.
How the public cloud can impact your business:
Public clouds typically deliver a pay-as-you-go model, where you pay by the hour for the compute resources you use. This is an economical way to go if you’re spinning up and tearing down development servers on a regular basis.
Because the public cloud is by definition a multi-tenant environment, your server shares the same hardware, storage and network devices as the other tenants in the cloud.
With the pay-as-you-go utility model, self managed systems are required for this business model to make sense. There is an advantage here for the technical buyers that like to setup and manage the details of their servers, but a disadvantage for those that want a fully managed solution.
Most public cloud deployments are generally used for web servers or development systems where security and compliance requirements of larger organizations and their customers is less of an issue.
