INTRODUCTION TO CLOUD COMPUTING
In order to provide quicker innovation, adaptable resources, and scale economies, cloud computing is the distribution of computer services over the Internet ("the cloud"), including servers, storage, databases, networking, software, analytics, and intelligence. The word "cloud" describes the software and databases that run on servers that may be accessed over the Internet. Users and businesses can avoid managing physical servers or running software on their own computers by utilizing cloud computing. We have summarized the cloud computing topic in cloud computing course mind map for the easy access of participants.
Because computation and storage occur on servers in a data centre rather than locally on the user device, users may access the same files and programmes through the cloud from nearly any device. This is how a user may continue access their previous Instagram account, complete with all of their old photographs, videos, and chat history, even after their old phone breaks. The same principles apply to cloud storage services like Dropbox or Google Drive as well as cloud email services like Gmail or Microsoft Office 365. By converting to cloud computing, businesses may reduce some of their IT expenses and administrative burdens. For example, they can stop updating and maintaining their own servers because the cloud provider they are using would take care of it for them. This has considerable impact, especially on small enterprises who would not have been able to finance their own internal infrastructure, but can outsource their infrastructure requirements via the cloud at a reasonable cost. The ability of employees and clients to access the same files and programmes from any place may also help businesses function abroad. The technology, services, and applications that are comparable to those on the Internet are taken and transformed into a self-service utility via cloud computing.
The two fundamental ideas are referenced by the word "cloud," Abstraction: Cloud computing shields consumers and developers from the specifics of system implementation. Applications operate on unspecified physical systems, data is kept in unidentified places, system administration is delegated to other parties, and user access is widespread. Virtualization: By pooling and sharing resources, cloud computing virtualizes systems. Resources are expandable with agility, multi-tenancy is supported, charges are calculated on a metered basis, and systems and storage may be added as needed from a centralized infrastructure. A pay-as-you-go, endlessly expandable, and widely accessible system, cloud computing is therefore the outsourcing technology of computer software that allows us to access programmes and data remotely. It doesn't need to be installed or stored on our computer's hard disc. In order to use the services online, we must just register. The delivery of cloud services is possible across both public and private networks (WANs, LANs, and VPNs). Email, video conferencing, and customer relationship management are all cloud-based apps (CRM). The complete information related to cloud computing training mind map, will give us an opportunity to learn.
TYPES OF CLOUD SERVICES
There are two main types of cloud services that we offer: cloud-based services and cloud-based services based on deployment models. You can find out where the cloud is situated and for what purposes from the deployment model. The four deployment models' NIST definitions are presented below. Anyone with an internet connection can utilize the public cloud infrastructure, which is controlled by a company that provides cloud services and is an example of this sort of deployment in the form of AWS, Rackspace, and Azure. The private cloud infrastructure, which is the other sort of cloud service, is run only for an organization's usage. The other type of cloud service, private cloud infrastructure, is solely used by one enterprise. On-premises or off-premises private clouds are also possible. Few instances Eucalyptus Systems, OpenNebula, and OpenStack are a few instances of this deployment approach. A hybrid cloud combines different clouds (private, communal, or public), each of which retains its own distinct identity while being joined as a single entity. Application mobility and standardized or proprietary access to data and apps may both be provided by a hybrid cloud. Examples of this deployment technique include Amazon, Cisco, and NetApp as examples of hybrid clouds. Anyone within a group of businesses may access systems and services thanks to the community cloud architecture. This may assist lower the capital expenditure costs for its establishment because the expenses are spread among the organizations. The organization(s) that make up the community cloud may administer it themselves or via a third party. The United States-based specialized IBM SoftLayer cloud for federal organizations is an excellent illustration of this kind of deployment. The sort of service that the cloud service provider is providing is described by the service models. Remote clients can access these services over the internet. As cloud computing has grown, several manufacturers now provide clouds that come with a variety of services. There are three service categories that are acceptable by all parties: Virtual computers, virtual storage, virtual infrastructure, and other physical assets are made available to clients as resources through IaaS. The customer is in charge of all other deployment-related tasks while the IaaS service provider controls the complete infrastructure. The operating system, programmes, and user interactions with the system might all fall under this category. PaaS offers operating systems, applications, virtual machines, services, transactional frameworks, and control structures. The customer has two options: either employ applications created with tools and languages offered by the PaaS service provider or install their own apps on the cloud infrastructure. The cloud infrastructure, operating systems, and supporting applications are all managed by the service provider. The programme that is being deployed must be installed and managed by the client. SaaS is an all-inclusive operating system that includes management, applications, and the user interface. In the SaaS model, the client receives the application through a thin client interface (often a browser), and the client is only accountable for entering and managing its data and user interaction. The vendor is in charge of everything, including the infrastructure and the application. The complete cloud computing syllabus has been coved in the mind map, which also includes topics such as Networking, Bigdata, AI etc.
The hardware and operating system of a server in a cloud data centre are referred to as the "cloud platform." It enables the distant and widespread coexistence of hardware and software products. Access to computing resources including servers, databases, storage, analytics, networking, software, and intelligence is rented by businesses. As a result, the businesses are relieved of the need to build and maintain data centres and computer equipment. They only pay for the things they consume. The market for cloud platforms and services is expanding quickly. A lot of computational power is required by contemporary technologies like big data analytics, IoT, artificial intelligence, and even hosting for web and mobile applications. Business organizations have an alternative to create their own internal infrastructure thanks to cloud computing and cloud platforms. Anyone who uses the internet may benefit from scalable processing capacity on a plug-and-play basis thanks to cloud computing. This has grown to be a highly popular option since it spares businesses from having to invest in and maintain expensive infrastructure. For the creation, administration, and distribution of apps, numerous businesses provide cloud platforms. The top 5 cloud platforms that one may utilize to efficiently handle an organization's IT requirements will be introduced in this talk.
