The Cloud, Part 1: Deployment
Simply put, cloud computing enables an individual or global organization to avoid investment in physical infrastructure —including servers, storage, databases, networking and software – in favor of a “pay as you go” model. This translates into greater flexibility (up and down) based on need, built-in ubiquitous access and payment for only the services actually used. There is no compromise to security, privacy or control.
Not all cloud environments are the same, however, and no single type of cloud computing is right for every business. The size of your company, the location of your employees, the current setup, future growth plans and budget are all considerations when deciding on the best use and deployment method.
Public clouds are owned and operated by a third-party cloud service providers that provide computing resources (servers, storage, databases, etc.). All that’s required is an Internet connection. Amazon Web Services (AWS), Google Cloud and Microsoft Azure are examples of the leading Cloud providers. Don’t let the word “Public” cloud fool you; just because you use AWS, Google or Azure doesn’t mean your information is available to the public. Quite the contrary. With a public cloud provider, all hardware, software, and other supporting infrastructure is owned and managed by the cloud provider. They lease the use of their environments for a very competitive price. Netflix uses AMS for their Cloud Computing needs.
A private cloud is a cloud computing environment that is used exclusively by a single business or organization. A private cloud’s hardware is physically located on the company’s on-site datacenter or in rented space, but the hardware – and all associated maintenance and support – is the responsibility of the organization.
A hybrid cloud environment combines public and private (on premises) infrastructure, linked together through technology that allows data and applications sharing between them. By allowing data and applications to move between private and public clouds, a hybrid cloud provides businesses greater flexibility, more deployment options, and helps optimize existing infrastructure, security, and compliance.
