Cloud Computing :
Cloud computing is a large data storage place where we can store a very large amount of data, and access services like networking, servers, databases, and online software applications development, and many other web development services. These types of services are provided by many cloud computing companies. when we compare to traditional data storage services like local drives, physically available data centers nearby, which are really the costliest ideas and also user need to be near to data center to access the services. and whereas Cloud computing services, it is the most efficient and cost-effective approach for data storage and also for web development services. In cloud computing services we can use the service, that how much we want to use the services only that much we need to pay. it is very easily accessible and we can use the service from anywhere and even from any remote areas also, it just needed an internet connection. and cloud computing is really good at performance, security, speed, and productivity.
There are three main types of cloud computing services :
1.SAAS (software as a service)
2.PAAS (platform as a service)
3.IAAS (infrastructure as a service)
Saas :
Software as a service is commonly used by small businesses, small organizations, or a single user. The saas cloud services, a user doesn't need to take care of regular updates, networking, and maintenance. This is simply that, if they are subscribing to a particular service for a certain period of time, for the product, or if they want to install a web application. They could just directly use the service with an internet connection without installing. Gmail is one of the well-known saas applications.
Paas :
Platform as a service is a cloud computing service that is very significant for the application development process. Developers don't need to stress about servers, storage, and networking and also about operating systems, software updates, infrastructure, PaaS service provides various tools and software components to design, create, and building of applications. It is highly scalable and also cost-effective for the development and deployment of applications and any changes can be made easily, and it's a virtual technology, multiple users can access the PaaS service in real-time.
Iaas :
Infrastructure as a service where users can access the services like servers, storage, networking. it's a cost-effective service for organizations like those who don't have data centers or can't afford a data center on their own. it is very convenient to score the data storage user doesn't need to invest in buying and maintaining hardware.
Types of cloud computing :
1.Public cloud computing
2.Private cloud computing
3Hybrid cloud computing
1.Public cloud computing :
In public cloud computing, the companies provide multiple renting systems. Where anyone can store their data as per their requirements. Consumers can use services like networking, servers, databases, online software application, and data storage. It has various models which provide, storage of data as per usage and as compare to private cloud computing public cloud computing is very cost-efficient, being a third-party hosting it is scalable on-demand its resources. public cloud computing services are more actively accessible to new technologies like AI and machine learning or any other IT industry technology and also easily get any updates in applications, because of their huge data structure and multiple tenant methods. And public cloud companies can be accessed from anywhere. It has remote access. Users could use services remotely with a high bandwidth connection.it is scalable in nature as volumes of storage increase public cloud computing provides the fastest way of calling up storage.
2.Private Cloud Computing :
The private cloud computing model works only for a single organization. private cloud computing is also known as internal cloud computing as well as corporate cloud computing because of its nature, the whole infrastructure of the data center is set up at the premises of the users and these entities have direct control over it. These are much more virtualized than the public cloud computing model, because of its security regulations. Private cloud computing is much more sensitive when it comes to security issues. Private cloud computing is quite expensive when compared to public cloud computing.
3.Hybrid Cloud Computing :
In this cloud computing model, the services of both public cloud computing and private cloud computing are put together is called hybrid cloud computing. The very nature of this hybrid cloud computing is to attain the best features of public and private cloud computing together. This cloud computing mostly prefers by the financial sector, security agencies, govt offices, and many more whose requirements are more dependent on security issues. The security issues concerns covered by private cloud computing while the other information which is not that much affects the sensitive nature of business. so, this type of data could be store in public cloud computing. In hybrid cloud computing, we can easily transform workloads from one another computing models.
