Cloud computing is a type of computing where files and programs are stored on
remote servers accessed over the internet, instead of on a local server or personal
computer. The cloud computing model allows users to access their data and
applications from any device or location, as long as they have an internet connection.
In the past, users would have to save their documents and files to a physical hard
drive, USB drive, or disk. With cloud computing, there is no need for any physical
hardware component.
Cloud computing services are classified into three broad categories:
software-as-a-service (SaaS), platform-as-a-service (PaaS), and
infrastructure-as-a-service (IaaS).
SaaS is the most prevalent type of cloud service. A lot of us use it on a regular basis.
SaaS delivers software over the Internet through an app or web browser. Some SaaS
solutions are free but many come with a monthly or yearly subscription fee to
continue using the service.
Requiring no hardware installation or management, SaaS solutions are a big
hit in the business world. Notable examples include Salesforce, Dropbox or
Google Docs.
Platform as a Service
PaaS is a cloud-based environment that helps with web application development
and deployment. It supports the full lifecycle of applications, from building to testing
to deploying to managing and updating. The service also includes development
tools, middleware and business intelligence solutions. Some notable examples of
PaaS providers are Windows Azure, AWS Elastic Beanstalk and Google App Engine.
Infrastructure as a Service
IaaS can be thought of as the foundation that other cloud services are built on. It
provides users with capabilities like data storage and servers, which are all housed in
the cloud. This type of service is appealing to businesses because it gives them
access to large programs and applications without having to invest in a physical
infrastructure. Some well-known IaaS providers include DigitalOcean, Amazon EC2
and Google Compute Engine.
Mechanism Of Cloud Computing
The cloud is a great place to store and share information. It's accessible from
anywhere there is an internet connection and it's relatively safe and secure. Cloud
applications have a host, which is the company responsible for maintaining the data
centers that provide the security, storage capacity and computing power needed to
maintain all of the information users send to the cloud.
The cloud is a major player in the hosting market, with companies like Amazon
(AWS), Microsoft (Azure), Apple (iCloud) and Google (Google Drive) being the most
prominent. However, there are also many other hosting companies, both large and
small. These companies can sell the rights to use their clouds and store data on their
networks. In addition, they offer users an ecosystem that can communicate between
devices and programs. For example, you can download a song on your laptop and it
will be instantly synced to iTunes on your iPhone.
It follows three delivery models:
1) Public
This is the most common and all of the players mentioned above (Amazon,
Microsoft, Apple & Google) run public clouds accessible anywhere with login
credentials and the right web app.
2) Private
This model offers the same kind of flexibility as the public cloud, but with the
infrastructure needs (hosting, data storage, IT staff, etc.) provided by the
companies or users of the service. Additionally, the restricted access and
hands-on management of hosting gives the private model an extra layer of
security.
3) Hybrid
Hybrid cloud computing is a combination of the public and private models.
The two cloud types are linked over the internet and can share resources
when needed (e.g., if the private cloud reaches storage capacity or becomes
corrupted, the public cloud can step in and save the day).
Cloud Application Development
Cloud application development is the process of building a Cloud-based app. This
process involves various stages of software development, which readies your app to
be launched. The best teams implementing Cloud app development use DevOps
practices and tools, such as Kubernetes. However, an experienced app development
company should be able to build your Cloud app using any technology you prefer.
The majority of apps built with Cloud technology are highly dependent on the Cloud
to function.
Application development on Cloud infrastructure has many benefits for businesses,
including reduced development costs, the ability to work with remote teams, and
shorter project timelines when used in conjunction with software development
methodologies like Agile. However, not all companies have the experience necessary
to perform all of the complex aspects of app development using the Cloud. As such,
businesses that are looking to develop digital products like web-based Cloud
applications need to ensure that they partner with a reputable and experienced
Cloud app development company.
Examples of cloud based applications
1) Miro
A virtual board is a great tool for collaborating with other users. You can use it
to share ideas, get feedback, and work together on projects in a number of fun
and creative ways.
2) Figma: a powerful Cloud-based design app that is gaining many fans thanks
to its collaborative nature.
3) Dropbox or Google Drive: easily store your files on the Cloud and make them
available for others, wherever they are.
Most Cloud-based apps don't lack any collaboration features. One major advantage of
Cloud apps is the ability to collaborate with users all over the world, even in real-time.
Advantage of cloud based applications
In cloud application development, the app’s data is stored in the cloud infrastructure
and could be partly cached on a user’s device. This means there are minimum
requirements for devices to run the application.
The cloud infrastructure can temporarily store information on a user’s device to allow
the user to access it while offline. Once the user is online again, the cloud app is
updated and uploads the generated data from offline to the cloud storage location.
You can set up backup schedules as well data optimization, compression and
encryption as a user in any way you want.
A cloud application can be accessed with the help of any internet-connected device,
including desktop, tablet, and mobile. This helps the user to get independent of
browser capacities.
Cloud-based applications also offer access to third-party cloud computing
