What is cloud computing?
Some of the services offered by cloud computing are servers, databases, storage networking, software, analytics, and intelligence over the Internet. It offers faster innovations, flexible resources and economies of scale.
In the case of a private cloud, It sells its services to anyone on the internet. A private cloud is an exclusive network or data center that supplies hosted services to a confined number of people. The main aim of cloud computing is to contribute an easy, upgraded access to computing resources and IT services. Cloud service providers are third party companies that launch public clouds, administer private clouds, offer on-demand cloud computing components and business applications. It is also known as cloud computing services. Some of the cloud applications that we use in our everyday life are Google Gmail or Salesforce, Streaming media like Netflix, or cloud file storage like Dropbox. Amazon Web Services (AWS) is the world’s most far reaching and widely adopted cloud platform.
Cloud computing architectures
Cloud computing architecture is a technology that allows both large and small organizations to store the information in the cloud. One can access it at any time, from anywhere using internet connection. It is a mixture of service oriented architecture and event driven architecture. The cloud computing architecture is divided into front end and back end. The main components of cloud computing architecture are client infrastructure, application and services.
Types of cloud computing
Public
A type of cloud computing where high-demand computing services and infrastructure are managed by a third-party provider. This is shared with multiple organisations via the public Internet. Public cloud service providers are allowed to offer cloud-based services like infrastructure as a service (IaaS), platform as a service (PaaS), or software as a service (Saas) to users for either a monthly or pay-per-use fee. This also allows the user to eliminate their need to host these services on the site in their own data center.
Private
A private cloud or an internal cloud is a cloud computing environment that dedicates all hardware and software resources to a single customer, which is accessible only by him. It accommodates many of the advantages of cloud computing, including flexibility ,adaptability, and ease of service delivery. A private cloud provides access control, resource customization and security of on-premises infrastructure.
Hybrid
Cloud computing is a combination of storage and service environments. It is made up of on-premises infrastructure, private cloud services, and a public cloud like Amazon Web Services (AWS). A hybrid cloud infrastructure means you have a combination of public clouds, on-premises computing, and private cloud in your data center.
Cloud service providers
A cloud service provider (CSP) is a third party company that offers components of cloud computing. They are mainly classified into infrastructure as a service (IaaS), software as a service (SaaS) or platform as a service (PaaS).
Infrastructure as a service
IaaS is one of the cloud computing services that extend necessary compute, storage and networking resources that are in demand, on a pre-pay basis. One can decrease maintenance of native data centres, save money on hardware costs and can achieve present business insights through IaaS solutions.
Platform as a service
It is a cloud computing service that delivers on-demand conditions for developing, testing, delivering and managing software applications. PaaS is developer friendly service that helps developers to create web or mobile apps without worrying about setting up or managing the underlying infrastructure of servers, storage, network and databases needed for development.
Software as a service
Using this method you can deliver software applications over the internet, on demand and largely on a subscription basis. In this cloud computing service, cloud service providers host and manage the software application and underlying infrastructure. They also handle software upgrades and security patching. A user can connect to the application using a web browser on their phone, tablet, or a PC.
If you are interested in using the cloud in your workplace, at home, or hope to set up a cloud computing network using Google or Amazon Web Service. There are a number of online courses where you can learn cloud computing online.
