Cloud computing is a model in which computing resources such as servers, storage, databases, and software applications are provided over the Internet. With cloud computing, businesses and individuals can access powerful computing resources without investing in expensive hardware or infrastructure. Alternatively, they can rent computing resources from cloud service providers for a fee on pay-as-you-go basis.

Cloud computing offers several advantages over traditional local computing. First, it provides scalability and flexibility, allowing users to scale up or down their computing resources quickly and easily as needed. Second, it reduces the need for capital investment in hardware and infrastructure, reducing costs and freeing up resources for other purposes. Third, it increases flexibility, allowing users to rapidly deploy new applications and services.

Before we explore more on cloud computing, lets look at the issues on on-prem environments.

On-Premises Computing Issues

On-premises computing can present several challenges, including the need for a large initial investment in hardware and infrastructure, the need for ongoing maintenance and support, and the risk of downtime or data loss in the event of hardware failure or other problems.

Businesses can face many challenges when it comes to on-premises IT issues. These include:

1. Cost: On-premises computing requires significant investments in hardware and infrastructure, and is expensive for businesses to acquire and maintain.

2. Scalability: Adding or removing computing resources in an on-premises environment can be time-consuming and require extensive planning and coordination.

3. Security: Managing the security of on-premises infrastructure can be challenging, especially for small organizations that do not have a dedicated security staff.

4. Disaster recovery: Home infrastructure is vulnerable to disasters such as fires, floods and power outages. Businesses must have a robust disaster preparedness plan in place to ensure they can quickly recover from any disruption.

Cloud Computing Advantages

There are many advantages to using cloud computing, including:

1. Scalability: Cloud computing allows users to easily expand or contract their computing resources as needed without requiring large investments in hardware and infrastructure. This makes it easy for companies to quickly respond to changing requirements or implement new applications.

2. Cost savings: Businesses can save on capital expenditures by leasing IT resources instead of investing in hardware and infrastructure. In addition, cloud computing often offer pricing models that allow businesses to pay only for the resources they use.

3. Agility: Because cloud computing resources are available on demand, it is easier for businesses to experiment with new applications or services. This can help companies innovate faster and stay ahead of the competition.

4. Improved security and reliability: Cloud computing providers typically invest heavily in security and reliability measures, such as encryption, data backup, and disaster recovery. This can give companies more confidence in the security and availability of their data.

Cloud Computing Risks

While cloud computing has many benefits, there are also some challenges and risks to be aware of. These include:

1. Provider Assurance: Because cloud providers use proprietary technologies and services, it can be difficult to change providers or migrate data to another platform.

2. Data Security and Privacy: Storing data in the cloud raises security and privacy issues, especially when sensitive data is involved. Cloud service providers may also be subject to different laws and regulations than local computing.

3. Trained personnel: Managing and operating cloud infrastructure requires specialized skills and knowledge. Companies may need to invest in training or hire new employees to manage their cloud resources effectively.

Cloud Computing Types

Cloud computing can be divided into three main types:

Infrastructure as a Service (IaaS): IaaS allows users to access virtualized computing resources, such as servers, storage, and networks, on a pay-per-use basis. This allows users to create their own virtual data centers in the cloud.

Examples:

• Amazon Web Services (AWS)

• Microsoft Azure

• Google Cloud Platform

• DigitalOcean

• Linode

Platform as a Service (PaaS): PaaS provides users with a platform to develop, test and deploy cloud applications. A platform usually includes an operating system, a programming language, and other tools for building and managing applications.

Examples:

• Heroku

• Google App Engine

• AWS Elastic Beanstalk

• Microsoft Azure App Service

• OpenShift

Software as a Service (SaaS): SaaS allows users to access software applications over the Internet without having to install and run the applications on their own devices. Examples of SaaS applications include email, CRM software, and project management tools.

Examples:

• Salesforce

• Microsoft Office 365

• Dropbox

• Slack

• Zoom

Cloud Computing Models

Cloud computing can also be implemented through a variety of models, including:

• Public cloud: In a public cloud deployment, computing resources are owned and operated by a third-party provider and made available to the public. Users usually access resources over the Internet.

• Private cloud: In a private cloud deployment, computing resources are assigned to one organization and not shared with other organizations. This can provide better control and greater data security.

• Hybrid cloud: Hybrid cloud deployment combines public cloud with private cloud resources, allowing organizations to take advantage of the scalability and cost savings of public cloud while maintaining control over sensitive data.

Cloud Providers

There are many cloud computing providers in the market, including:

1. Amazon Web Services (AWS): AWS is one of the most popular cloud computing platforms, offering a wide range of services such as computing, storage and databases.

2. Microsoft Azure: Azure is Microsoft’s cloud computing platform that offers a variety of services, including virtual machines, storage, and networking.

3. Google Cloud Platform (GCP): GCP is Google’s cloud computing platform, which provides computing, storage, machine learning and other services.

4. IBM Cloud: IBM Cloud is IBM’s cloud computing platform that provides services such as computing, storage, and artificial intelligence.

5. Oracle Cloud: Oracle Cloud is Oracle’s cloud computing platform, offering services including compute, storage, and databases.

As of 2021, AWS dominates the cloud computing market with approximately 32% market share. Microsoft Azure is the second largest provider with around 20% market share, followed by Google Cloud Platform with 9% market share.
