Cloud Computing

Given below are some of the challenges of cloud computing applications and services:

• Security Concerns: With many companies participating in cloud computing practices, it is a tedious task to ensure the safety of the data being shared or operated on these platforms.
• Increasing cost: Cloud computing services are often accompanied by huge bills, making them unaffordable for many.
  High Dependence on Network: Cloud computing services can only be accessed when good quality network connectivity is available at all times.
• Lack of Expertise: Due to the complex nature and high demand for research, working with the cloud often ends up being an extensive task. Even the professionals need to stay updated. Sometimes it can be quite a task to keep up with the ever-changing and evolving technologies.
  
  
  

There are three main types of services provided by cloud computing such as IaaS (Infrastructure-as-a-Service), PaaS (Platform-as-a-Service), and SaaS (Software-as-a-Service):-

• IaaS: IaaS provides the customers virtualized computing resources through the internet, example: servers, storage, etc. Customers can use these type of resources without worrying about the physical hardware or maintenance. Thus, providing greater flexibility as well as cost-effectiveness compared to traditional on-premise solutions.
• PaaS: PaaS provides customers a platform for the purpose of developing, running, and managing their applications. The platform includes elements like infrastructure, tools, and services for development, deployment, and maintenance.
• SaaS: SaaS provides customers with access to software applications over the internet without having to install them on their computers. Customers pay a fee to access the software, usually on a subscription basis. Thus, it is very efficient for small organizations or individuals who want to use software without the hassle and cost of setting it up and maintaining it themselves.
