Cloud computing is the delivery of computing services like servers processing, storage disks, networking components, software services, data analytics and other components over the Internet or Web (aka cloud). Companies offering these computing services are called cloud providers and typically charge for cloud computing services based on usage, similar to how you are billed for your mobile phone usage.
Cloud computing is a big shift from the traditional way businesses think about IT resources. What is it about cloud computing? Why is cloud computing so popular?
Here are some of few common reasons organizations are turning to cloud computing services:
1. Cost optimization: Cloud computing eliminates the capital expenditure by eliminating need of buying hardware and software and setting up and running on-site datacenters—the racks of servers, the round-the-clock electricity for power and cooling, the IT experts for managing the infrastructure. It adds up fast.
2. Speed enhancement: Provision vast amounts of computing resources with few clicks, giving businesses a lot of flexibility and taking the pressure off capacity planning.
3. Global availability: Delivering the right amount of IT resources like computing power, storage, bandwidth—right when it’s needed and from the right geographic location.
4. Improved productivity: Cloud computing removes the need for many of these tasks, so IT teams can spend time on achieving more important business goals.
5. Performance boost: With worldwide network of secure datacenters, you can benefit with reduced network latency for applications and greater economies of scale.
6. Reliability of applications: Cloud computing makes data backup, disaster recovery and business continuity easier and less expensive, because data can be mirrored at multiple redundant sites on the cloud provider’s network.
Most cloud computing services fall into three broad categories: infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (Saas). These are sometimes called the cloud computing stack, because they build on top of one another. Knowing what they are and how they are different makes it easier to accomplish your business goals.
Infrastructure-as-a-service (IaaS): The most basic category of cloud computing services. With IaaS, you rent IT infrastructure—servers and virtual machines (VMs), storage, networks, operating systems—from a cloud provider on a pay-as-you-go basis.
Platform as a service (PaaS): Platform-as-a-service (PaaS) refers to cloud computing services that supply an on-demand environment for developing, testing, delivering and managing software applications.
Software as a service (SaaS): Software-as-a-service (SaaS) is a method for delivering software applications over the Internet, on demand and typically on a subscription basis.
InnovaPoint can help you with three different ways to deploy or migrate your existing or new applications over cloud: public cloud, private cloud and hybrid cloud.
Public cloud: Public clouds are owned and operated by a third-party cloud service provider, which deliver their computing resources like servers and storage over the Internet. You access these services and manage your account using a web browser.
Private cloud: A private cloud refers to cloud computing resources used exclusively by a single business or organization. A private cloud can be physically located on the company’s on-site data center.
Hybrid cloud: Hybrid clouds combine public and private clouds, bound together by technology that allows data and applications to be shared between them. By allowing data and applications to move between private and public clouds, hybrid cloud gives businesses greater flexibility and more deployment options.
