Cloud Computing - The Basics

Moving to the cloud. Running in the clouds. Stored in the clouds. Reached from the cloud: these days it seems like everything is happening "in the cloud". But what exactly is this absurd idea? Cloud as the name suggests is present at the end of your internet connection, somewhere you can obtain access over apps and services, and where your data can be stored securely.

What is Cloud Computing?

Cloud computing is the practice of using a network of remote servers hosted on the internet to store, manage, and process data, rather than using a local server or personal computer. It allows individuals and businesses to access and utilize computing resources on-demand, such as storage, databases, software, and applications, without the need for physical infrastructure. 

With cloud computing, users can easily scale resources as needed, access data and applications from anywhere with an internet connection, and pay only for the services they use. This flexible and cost-effective approach has revolutionized the way we store and access information, enabling seamless collaboration, improved efficiency, and enhanced data security.

Why cloud computing?

• Flexibility and Scalability: Cloud computing allows for easy scalability, enabling users to quickly adjust their computing resources based on demand.
• Accessibility: Cloud-based services can be accessed from anywhere with an internet connection, promoting remote work and collaboration.
• Cost Efficiency: Cloud computing eliminates the need for on-site servers and infrastructure, reducing capital expenditures. Users only pay for the resources they use, resulting in cost savings.
• Data Security and Reliability: Cloud providers employ robust security measures and backup systems to ensure data integrity and availability.
• Integration and Innovation: Cloud computing facilitates seamless integration with other technologies, enabling businesses to leverage advancements in AI, machine learning, and big data analytics.
• Disaster Recovery: Cloud-based systems offer reliable backup and disaster recovery capabilities, ensuring business continuity in case of unforeseen events.
• Simplified IT Management: Cloud providers handle system maintenance, updates, and security, freeing up resources for other business activities.
• Collaboration and Productivity: Cloud-based tools and applications promote collaboration among teams and enhance overall productivity.
• Environmental Sustainability: Cloud computing reduces the carbon footprint by optimizing server utilization and energy efficiency.
• Competitive Advantage: Adopting cloud computing allows organizations to stay agile, innovate faster, and gain a competitive edge in the rapidly evolving digital landscape.

How does Cloud Computing work?

Cloud service providers enable users to store files and applications on remote servers and access all data via the Internet. This means that the user does not have to be in a certain place to access it, allowing the user to work remotely.

Cloud computing can be both public and private. Public cloud services offer their services online for a certain amount of money. Private cloud services provide services to a certain number of people or a private group. These services are a network of networks that provide hosted services. There is also a hybrid option, which includes both public and private services.

Types of Cloud Computing- services

Cloud computing is not just one piece of technology like a microchip or mobile phone. Cloud computing services are software-as-a-service (SaaS), infrastructure-as-a-service (IaaS), and platform-as-a-service (PaaS).

IaaS - Infrastructure as a service

Infrastructure-as-a-service (IaaS) includes a way to deliver everything from operating systems to servers and IP-based connectivity as part of the desired service. Clients can avoid the need to purchase software or servers, and instead purchase these services from an exported, much-needed service. IaaS provides computer-based computer services hosted by a third party such as Amazon Web Services, Microsoft Azure or Google.

PaaS - Platform as a service

A platform as a service (PaaS) allows organizations to build, operate and manage applications outside of IT infrastructure. This makes it easier and faster to develop, test and distribute applications. Developers can focus on coding and implementing applications without having to worry about time-consuming IT infrastructure tasks such as providing servers, maintenance and backup. PaaS brings additional value to the cloud. It can reduce your management more and reduce your costs. PaaS also makes it easy for you to update and rate your services on demand. Google and Heroku Application Engine, which allows developers to build and run applications fall under PaaS.

SaaS - Software as a service

Software-as-a-service (SaaS) implements a software application license to customers. Licenses are usually issued in a pay-as-you-go model or on-demand. This type of program can be found in Microsoft Office 365. General Option for Independent Users: Customer purchases monthly subscriptions and uses certain software options directly from the provider's platform. The provider is responsible for the installation, configuration and operation of the interface. 

Some examples:

• Square, which operates an online payment
• Google applications such as Google Drive or Calendar
• Slack, which allows interaction and chat between other users

Functions as a service (FaaS)

FaaS is a new and very innovative cloud computing service that works as a game-changer for many businesses. It is a seamless computer concept that allows software developers to develop applications and use each “function”, piece of business idea, or action without saving the server. It increases efficiency as developers do not need to consider server performance because they are trapped externally. 

The major cloud delivery models include:

• Public Cloud
• Private cloud
• Hybrid Cloud
• Community Cloud

Public Cloud

As the name suggests a public cloud is a kind of computing in which a service provider makes resources accessible to the public over the internet. This is a very cost-effective way for organisations that do not wish to invest in IT infrastructure. In the Public Cloud environment, resources are shared among multiple users called 'Employers'. The cost of using Cloud services is determined by the use of IT resources used. 

Private Cloud

Individuals or organizations that adopt Private Cloud obtain dedicated infrastructure that is not shared with another person or organization but is sole to themself. The level of security and control is very high while using a private network. Costs are borne by an individual/organization and are not shared with another person/organization. Private Cloud Management is managed by the user and CSP does not provide cloud management services.

Hybrid Cloud

This cloud deployment model incorporates features of Public and Private Cloud. Hybrid Cloud allows for the sharing of data and applications between the public and private areas of the Cloud. Organizations mainly use the Hybrid Cloud where their On-Premise infrastructure needs more scale, so they use the decline in the Public Cloud to meet the changing business needs. Organizations can store sensitive information in their Privacy Clouds while harnessing the power of the Public Cloud.

Community Cloud

Community Cloud is a cloud infrastructure shared by users belonging to a particular community such as the same industry or similar goals. This cloud infrastructure is built on the understanding of the computer needs of the public as there are many things that involve compliance with security policies that must be included in the public cloud infrastructure.

Cloud Computing Benefits:

1) Backup and restore data

When data is stored in the cloud, it's easy to back up and restore that data using the cloud.

2) Improved interaction

Cloud applications boost cooperation and collaboration by allowing groups of people to swiftly and effortlessly share information in the cloud with shared storage.

3) Excellent accessibility

The cloud allows us to quickly and easily access store information anywhere, anytime in the world, using an internet connection. Internet cloud infrastructure enhances organizational productivity and efficiency by ensuring that our data remains accessible.

4) Low maintenance costs

Cloud computing reduces both the cost of computer hardware and software for organizations.

5) Travel

Cloud computing allows us to easily access all cloud data on a mobile device.

6) Services in the model of payment usage

Cloud computing provides Application Programming Interfaces (APIs) to users of cloud accessibility services and pays for the use of the application.

7) Unlimited storage capacity

The cloud provides us with a large amount of storage space to store our important data such as documents, photos, audio, video, etc. in one place.

8) Data security

Data security is one of the major benefits of cloud computing. Cloud offers many advanced security-related features and ensures that data is stored securely and managed.
