Cloud computing services are changing the way businesses and institutions use information technology. Cloud services are available to meet any IT need requirements. Cloud computing is the delivery of computing services like servers, storage, databases, networking, software, analytics, intelligence and much more over the Internet to offer flexible resources, faster innovation, and economies of scale. You pay only for what you use, cutting down your IT operating costs, run your IT infrastructure more efficiently, and scale as your business needs change.
Business those shift their IT infrastructure into cloud need at least some basic knowledge of how it Cloud Computing works and the benefits they will get after moving to cloud platform. Cloud computing is still a new technology and is expanding in terms of usability and features. The cloud computing is attractive for small, medium & large business but some can say with certainty that they understand the cloud completely? Cloud computing is a big shift from the traditional way of managing and maintaining IT infrastructure. Below are the benefits of cloud computing services and the reason organizations are shifting to cloud:
There are three different ways to deploy cloud computing services: on a public cloud, private cloud, or hybrid cloud.
Public clouds refers to public cloud hosting solutions is cloud computing model are owned and managed by cloud service providers, which deliver their computing resources like virtual machines, servers and storage to general public over the Internet. You access these computing services and manage your account using a web browser. Microsoft Azure, AWS, Google Cloud are an example of a public cloud.
A private cloud refers to private cloud hosting solutions is cloud computing service in which resources used exclusively by a single business or enterprise. A private cloud can be located on the company’s on-premises datacenter. A private cloud is one in which the services and infrastructure are maintained on a private network. Private cloud is a type of cloud computing model that delivers similar advantages to public cloud, including scalability and self-service, but enterprise itself owns and operates the private cloud.
Hybrid clouds refers to hybrid cloud hosting solutions is a mix of both public and private clouds, that allows data and applications to be shared between them. Hybrid cloud gives your business greater flexibility, more deployment options, and helps optimize existing infrastructure, security, and compliance by allowing data and applications to move between private and public clouds.
The wide range of cloud services offered by cloud computing service providers can be categorized into three basic types: infrastructure as a service (IaaS), platform as a service (PaaS), serverless, and software as a service (SaaS). These are sometimes also called the cloud computing stack because they build on top of one another.
IaaS is the basic category of cloud computing services. With IaaS, you rent IT infrastructure – virtual machines (VMs), servers, storage, networks, operating systems from a cloud service provider on a pay-as-you-go basis.
Platform as a service refers to cloud computing services that provides on-demand developing platform layer, for developing, testing, delivering, and managing software applications. PaaS is designed to make it easier for developers to quickly create applications, without setting up or managing the infrastructure of servers, storage, network, and databases, software development kits (SDKs) for various programming languages needed for development.
Software as a service offers software applications tailored to a wide variety of business needs over the Internet, on demand and on a subscription basis. In SaaS, cloud service providers host and manage the software applications and infrastructure, handle maintenance, like software upgrades and security patching. Users connect to the application hosted on cloud over the Internet, usually with a web browser on their mobile, pc or laptop.
