1. Cloud Computing
Cloud Computing, as name suggests, is collective combination of configurable system resources and advanced service that can be delivered quickly using internet. It simply provides lower power expenses, no capital costs, no redundancy, lower employee costs, increased collaboration, etc. It makes us more efficient, more secure, and provide greater flexibility. 

Advantages of Cloud Computing :

  • Scalability: Cloud computing allows organizations to easily scale their computing resources up or down as their needs change, without having to purchase and manage additional hardware.
  • Cost Savings: Using cloud computing can be more cost-effective than maintaining on-premises IT infrastructure, as it eliminates the need for costly hardware, software, and maintenance expenses.
  • Accessibility: Cloud computing enables remote access to applications and data, allowing users to work from anywhere with an internet connection.
  • Reliability: Cloud providers offer high levels of uptime and redundancy, ensuring that applications and data are available even in the event of hardware failure.
  • Flexibility: Cloud computing offers a wide range of deployment options, including public, private, and hybrid clouds, which can be tailored to meet the unique needs of an organization.

Disadvantages of Cloud Computing :

  • Security: Cloud computing involves sharing sensitive data with a third-party provider, which raises concerns about data security and privacy.
  • Dependence: Organizations that rely on cloud providers for their computing infrastructure are vulnerable to service disruptions or data loss in the event of provider outages or other issues.
  • Internet Dependency: Cloud computing requires a reliable and fast internet connection to access applications and data, which can be a challenge in some areas.
  • Technical Issues: Technical issues with cloud services, such as compatibility problems or software bugs, can sometimes be difficult to resolve and can result in downtime or lost productivity.
  • Lack of Control: With cloud computing, organizations have limited control over the infrastructure and services they use, which can make it difficult to customize or optimize the environment for their specific needs.

2. Traditional Computing : 
Traditional Computing, as name suggests, is a possess of using physical data centers for storing digital assets and running complete networking system for daily operations. In this, access to data, or software, or storage by users is limited to device or official network they are connected with. In this computing, user can have access to data only on system in which data is stored.

Advantages of Traditional Computing :

  • Control: With traditional computing, an organization has full control over the hardware and software it uses, allowing for customization and optimization of the computing environment.
  • Security: Traditional computing offers a high level of data security, as sensitive data can be stored on-premises and protected by firewalls, encryption, and other security measures.
  • Reliability: Traditional computing is not dependent on internet connectivity, making it less vulnerable to service disruptions or data loss.
  • Compatibility: Traditional computing environments can be tailored to meet the specific needs of an organization, ensuring compatibility with existing software and systems.
  • Data Ownership: With traditional computing, an organization owns and controls all of its data, reducing concerns about data privacy and regulatory compliance.

Disadvantages of Traditional Computing :

  • Cost: Traditional computing can be more expensive than cloud computing, as it requires significant capital expenditures for hardware and software, as well as ongoing maintenance and support expenses.
  • Scalability: Traditional computing can be difficult to scale up or down to meet changing needs, as it requires additional hardware or software to be added to the environment.
  • Accessibility: Traditional computing may not allow for remote access to applications and data, limiting the ability of users to work from anywhere.
  • Maintenance: Traditional computing environments require ongoing maintenance and upgrades to ensure security and performance, which can be time-consuming and expensive.
  • Limited Storage Capacity: Traditional computing environments may have limited storage capacity, requiring organizations to periodically purchase additional hardware to accommodate growing data volumes.

    Difference between Cloud Computing and Traditional Computing :

Cloud Computing

Traditional Computing 

It refers to delivery of different services such as data and programs through internet on different servers. It refers to delivery of different services on local server. 
It takes place on third-party servers that is hosted by third-party hosting companies.   It takes place on physical hard drives and website servers.  
It is ability to access data anywhere at any time by user.   User can access data only on system in which data is stored.  
It is more cost effective as compared to tradition computing as operation and maintenance of server is shared among several parties that in turn reduce cost of public services.  It is less cost effective as compared to cloud computing because one has to buy expensive equipment’s to operate and maintain server.  
It is more user-friendly as compared to traditional computing because user can have access to data anytime anywhere using internet.  It is less user-friendly as compared to cloud computing because data cannot be accessed anywhere and if user has to access data in another system, then he need to save it in external storage medium.  
It requires fast, reliable and stable internet connection to access information anywhere at any time. It does not require any internet connection to access data or information.  
It provides more storage space and servers as well as more computing power so that applications and software run must faster and effectively.   It provides less storage as compared to cloud computing.  
It also provides scalability and elasticity i.e., one can increase or decrease storage capacity, server resources, etc., according to business needs.   It does not provide any scalability and elasticity.  
Cloud service is served by provider’s support team.   It requires own team to maintain and monitor system that will need a lot of time and efforts.  
Software is offered as an on-demand service (SaaS) that can be accessed through subscription service.   Software in purchased individually for every user and requires to be updated periodically.
