Cloud computing is a term used for anything that includes delivering hosting services across the net. There are 3 main categories of these services like IaaS (infrastructure as a service), PaaS (platform as a service) and SaaS (software as a service). Cloud can be public or private. A public cloud can sell services to anyone on the internet. Whereas, a public cloud is a data centre or a proprietary network that supplies hosted services only to a limited number of people with access and permissible settings. Whether it’s public or private, the goal of cloud computing is to provide scalable and easy access to computing resources and IT services.
The name Cloud Computing was inspired by cloud symbols and is often used for representing the internet in diagrams and flowcharts. Cloud infrastructure includes software and hardware components that are required for proper implementation for a cloud computing model.
How does it work?
Cloud computing allows client devices in accessing data over the internet from databases, computers and remote servers. The internet connection links the front end (that includes accessing client browser, device, network and software applications) with a back end that includes servers, computers and databases. The back end actually operates as a repository, store data that is accessible by the front end. Communication between the front and the back end is handled by a central server. The central server relies on protocols for facilitating the exchange of data and uses both middleware and software for managing the connectivity between the divergent cloud servers and client devices. Usually, there is a dedicated server for every application.
Examples of Cloud Computing
Google Docs, Microsoft Office 365: Accessing Google Docs and Microsoft Office 365 through the internet is easier and more productive as work presentations and spreadsheets can be stored in the cloud and are accessible anytime, anywhere from any device.
Email, Calendar, Skype, WhatsApp: With Cloud, one can access their personal data from emails, calendars, Skype and WhatsApp remotely, from any device and wherever and whenever they want.
Zoom: A cloud-based software zoom is a platform for audio and video conferencing that can be used to record meetings and save them on the cloud. Users can access these recordings anytime from anywhere.
AWS Lambda: With Lambda developers run code for applications and back end services without provision and managing the servers. This pay-as-you-go model scales with the organization for accommodating real-time alterations in data storage and usage.
Why use Cloud Computing?
Self Service Provisioning
The end users spin up compute resources for any kind of workload on-demand. The end-user can provision computing capabilities like server time, network storage and eliminate the need of IT administrators for provision and management of computing resources.
A company can freely scale up and scale down computing needs as per their needs and requirements. This helps to save costs and manage investments according to the need of the hour.
Pay Per Use
The compute resources are managed at a granular level that would help the users to pay based on the resources and workloads that have been utilized.
Service providers implement resources for ensuring resilient storage and also keeps user workload running and moving across multiple global regions.
Broad Network Access
The user can access cloud data and also upload data from anyplace with an internet connection by using any device.
Want to move workloads to different cloud platforms automatically? Then, it’s possible without burning a hole in your pocket and also utilizing new services as they merge.
Multi-tenancy and Resource Pooling
With this feature, multiple customers can share similar physical infrastructure or similar applications without compromising on privacy and data security. With resource pooling, cloud service providers aid multiple customers from similar physical resources. The resource pools are large and flexible for servicing the requirements of numerous customers.
Top Benefits of Cloud Computing
Cost-cutting – With Cloud computing, organizations save on costs and don’t have to spend money on buying and maintaining any equipment. In this way, capital investment costs go down. Additionally, Cloud computing cuts costs related to downtime, as downtime rarely happens, companies don’t need to fix issues related to downtimes like handling cloud data centre operations and the like.
Mobility – When a piece of information is stored in the cloud, it means the data can be accessed from anywhere through any device without any internet connection. Corporate data can be accessed via smartphones enabling remote employees to stay updated with co-workers and clients.
Disaster Recovery – Worried about data loss? Data storage in the cloud guarantees users to access the data quickly in the event of any emergencies like natural disasters and power outages.
