Each model represents a different part of the cloud computing stack because they build on top of one another and build a business service model for the customers as per need. Small and medium businesses that have just started and do not have enough funds to spend on their IT infrastructure can use SaaS. If a data center goes down or a server crashes, the infrastructure remains unaffected. These resources are provided to you through virtualization. The data is made accessible to multiple users via an online service. There are three cloud computing models used for deployment: Owned by a third-party vendor, these cloud services are free to use and openly provided to the public. Cloud Service Models. Organizations use their own platforms and applications within a service provider’s infrastructure. Public cloud can include shared, dedicated and bare metal delivery models. These cloud computing resources are deployed for a particular organization. You also get pre-built tools and APIs to customize your applications. The pay-as-you-go model helps you save costs. Cloud Computing Models. It can be located at the company’s. This provides better flexibility and deployment options to an organization. Examples of IaaS include AWS (Amazon Web Services), DigitalOcean, and Microsoft Azure. or the vendor’s datacenter. You just have to pay for their services to use them. As all your data resides on the cloud, there is no single failure point. As per the size of a business, technical requirements, and budget, companies can choose the service they want. Cloud computing refers to offering computing services from servers in a network. Also Read: 6 Interesting Cloud Computing Project Ideas & Topics For Beginners. After choosing the cloud service model and the cloud type offered by vendors, customers need to plan the infrastructure architecture. It is a computing infrastructure managed over the internet. Fully and partially managed clouds are also options. Popular SaaS products include DropBox and Salesforce. You just have to pay for their services to use them. Figure - Components of Cloud Infrastructure: The hypervisor can be defined as the firmware (a permanent set of instruction or code programmed into the read-only memory & is a low-level program) that acts as a virtual machine manager. This, in turn, leads to better software development and even faster deployment. NIST defines four cloud deployment models: public clouds, private clouds, community clouds, and hybrid clouds.A cloud deployment model is defined according to where the infrastructure for the deployment resides and who has control over that infrastructure. The three models that you will come across are – IaaS, PaaS, and SaaS. So, when it comes to cloud computing vs. conventional IT infrastructure models, the cloud is the better option, if the only aspect of cloud security is taken care of by enterprises, which is possible to deploy CASB solutions, which go hand-in-hand with cloud providers.
