Why developer like cloud computing

benefits of cloud computing

What is cloud computing, in easy terms?

Cloud computing is the delivery of on-demand computing services – from servers, storage, databases, networking, software, analytics, power, processing to intelligence – typically all over the internet and on a pay-as-you-go basis.

It is like renting an apartment in a campus having all the facilities like gym, pool, spa, stores etc. instead of building your own, you need not have to invest to build them instead you enjoy as you pay in shared mode.

Benefits of cloud computing

Elasticity

When your application or IT services are growing or having unpredictable demand then Cloud-based services are ideal for you. You can scale up horizontally or vertically – that means delivering the right amount of IT resources —for example, more or less computing power, storage, and bandwidth.

Disaster recovery

Majority of companies should be investing in robust disaster recovery, but for smaller companies the lack of required cash and expertise sometimes bar them to invest. Cloud is now helping all size of organizations buck that tendency.

Automatic software updates

In changing world software are also upgrading with faster pace which require organizations to put time and efforts, but good news is – Cloud provider take care of these type of recurrent activities for you and roll out regular software updates – including security patches. Leaving you free to focus on the things that matter, like growing your business, handling customers.

Low Cost

Cloud computing reduces the high cost of hardware. You simply pay as you go and enjoy a subscription-based model that helps you to cut down you capital expanses – Research by Oracle found that two thirds of cloud users said using online infrastructure makes it easier to innovate, had cut their time to deploy new applications and services and had significantly cut on-going maintenance costs.

Increased collaboration

People can collaborate more when they can access, edit and share documents, data, code etc. anytime, from anywhere, and do it in better way. Cloud enabled them to make edit, updates and deploy in real time and gives them full visibility of their cooperation.

Security

Many cloud providers offer a range of policies; technologies and controls that strengthen security posture overall, helping protect data, apps and infrastructure from potential threats. Even losing your laptops doesn’t matter as your data is stored in the cloud, you can access it no matter what happens to your device.

Global landscape

With cloud it is possible to scale up and reach out to the customers in global space with consistent performance of your application across geo locations. Different CDN services, Cache algorithms, translation and internationalization components help to create world class applications.

Environmentally friendly

While the above points imply benefits of cloud computing for your organization, moving to the cloud isn’t an entirely self-interested act. The environment gets a little benefit too. When your cloud needs push, your server capacity scales up and down to fit, you only use the energy you need and you don’t leave oversized carbon footprints.

Types of Cloud

Public cloud

Public clouds are owned and managed by third-party cloud service providers, which deliver their computing resources like servers, storage and several services over the Internet. Microsoft Azure, Amazon Web Services (AWS), Google Cloud Platform (GCP) are some examples of a public cloud. You just need to access these services and manage your account using a web browser.

Private cloud

A private cloud refers to cloud computing resources used entirely by a single business or organization. A private cloud can be physically placed in the company’s premise or inside on-site datacenter. Some companies also pay third-party service providers to host their private cloud. A private cloud is one in which the services and infrastructure are maintained on a private network.

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, a hybrid cloud gives your business greater elasticity, more deployment options and helps optimize or control your existing infrastructure, security and compliance.

Cloud Services

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 refers to cloud computing services that supply an on-demand environment for developing, testing, delivering and managing software applications. PaaS is designed to make it easier for developers to quickly 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 (SaaS)

Software as a service is a method for delivering software applications over the Internet, on demand and typically on a subscription basis. With SaaS, cloud providers host and manage the software application and underlying infrastructure and handle any maintenance, like software upgrades and security patching. Users connect to the application over the Internet, usually with a web browser on their phone, tablet or PC.

Serverless computing

Overlapping with PaaS, serverless computing focuses on building app functionality without spending time continually managing the servers and infrastructure required to do so. The cloud provider handles the setup, capacity planning and server management for you. Serverless architectures are highly scalable and event-driven, only using resources when a specific function or trigger occurs.
