When you stream your favorite album online, shop at an e-commerce store or answer your work email from your home computer, you’re reaping the benefits of cloud computing.
Cloud computing is a form of computing in which networks, data storage, applications, security and development tools are all enabled via the Internet, as opposed to a local computer or an on-premise server in your organization.
If you use a computer or mobile device at home or at work, you almost certainly use some form of cloud computing every day, whether it’s a cloud application like Google Gmail or Salesforce, streaming media like Netflix, or cloud file storage like Dropbox. According to a recent survey, 92% of organizations use cloud today and most of them plan to use it more within the next year.
Public cloud is a type of cloud computing in which a cloud service provider makes computing resources available to users over the public internet. These resources might be accessible for free, or access might be sold according to subscription-based or pay-per-usage pricing models.
The public cloud provider owns, manages, and assumes all responsibility for the data centers, hardware, and infrastructure on which its customers’ workloads run, and it typically provides high-bandwidth network connectivity to ensure high performance and rapid access to applications and data.
Private cloud is a cloud environment in which all cloud infrastructure and computing resources are dedicated to, and accessible by, one customer only. Private cloud combines many of the benefits of cloud computing, including elasticity, scalability, and ease of service delivery, with the access control, security, and resource customization of on-premises infrastructure.
A private cloud is typically hosted on-premises in the customer's data center. But a private cloud can also be hosted on an independent cloud provider’s infrastructure or built on rented infrastructure housed in an offsite data center.
Hybrid cloud is just what it sounds like, a combination of public and private cloud environments. Specifically, and ideally, a hybrid cloud connects an organization's private cloud services and public clouds into a single, flexible infrastructure for running the organization’s applications and workloads.
Multicloud is the use of two or more clouds from two or more different cloud providers. Having a multicloud environment can be as simple as using email from one vendor and image editing from another. But when enterprises talk about multicloud, they're typically talking about using multiple cloud services from two or more of the leading public cloud providers. In one survey, 85% of organizations reported using multicloud environments.
Hybrid multicloud is the use of two or more public clouds together with a private cloud environment.
Traditionally, security concerns have been the primary obstacle for organizations considering cloud services, particularly public cloud services. In response to demand, however, the security offered by cloud service providers is steadily outstripping on-premises security solutions.
