[[What is cloud computing and its advantages?]] Cloud computing refers to sharing information , software, resources through a network. This is the process of using series of remote servers that are hosted on the internet which are used to store, manage the data, instead of using local servers. Let us discuss in detail : It is can be described as the delivery of computing services over the internet. Mostly the computing services include servers, databases, analytics, networking, storage,etc… Through this you can store and access the information over the internet. There are some organizations that render cloud services they are known as cloud service providers. Especially there shall be cloud service architect(https://www.fieldengineer.com/skills/cloud-services-architect ) who shall take care of services. We use cloud for our daily activities such as email services, watching movies, listening to music, other online activities,etc…. Advantages of Cloud Computing: Today many organizations are shifting towards cloud due to the following benefits: Performance: They should be upgraded based on the development changes, computing hardware & new innovations. Dependability: Cloud Computing supports data backup thus preventing data loss and it helps to recover the data(Business Information). It's more affordable. Reduces Infrastructure Costs: With the help of cloud computing operational cost is reduced compared to other traditional methods. Typically IT infrastructure involves Servers, network switches & licensing fees. In addition to this it requires other hardware components , installation of secure systems, etc…. With the help of cloud computing we can avoid these costs and a system administrator is enough to look after theses things & also there are a lot of automation processes involved. Speed & Efficiency: It drives a speedy response environment which is very important for IT sector. It helps to achieve the prerequisites of IT service. Thus it helps developers to spend time in crucial business objectives. Classification of cloud Computing: Cloud computing is classified into 3 types: Infrastructure as a service (IaaS) Platform as a service (PaaS) Software as a service (SaaS) Infrastructure as a Service (IaaS): This supports in renting IT infrastructure. Eg: virtual machines, servers, storage,networks,etc.. Platform as a Service (PaaS): This helps in supplying OnDemand platform (https://www.fieldengineer.com/) that supports in developing, testing delivering & managing software APPS. It helps developers in building software APPS and web design. Software as a service (SaaS): It allows cloud providers to host and manage software APPS. Article Source: https://bit.ly/2kG2053
