- [Narrator] Different types of cloud deployment models. Now that we are familiar with Azure and its history, let's learn about types of cloud deployment models. It is important to note that not all clouds are same. Further, there are several cloud computing models that have evolved over time to meet the rapidly changing needs of the industry. Let us learn about three different types of cloud deployment models that are commonly used in the industry: public cloud, private cloud, and hybrid cloud. Now that we are aware about the different types of deployment models, let us learn about each one of them. Firstly, let us start with the public cloud. Public cloud is one of the most common types of cloud deployment model that is owned and operated by a third party cloud service provider. Microsoft Azure is the second largest public cloud provider in the industry. You can access the cloud services and manage your account using a web browser. Azure provides your web portal where you can just log in and use all the public services. Some of the major advantages of using public cloud include: lower operational cost, lesser maintenance overhead, high reliability, and nearly unlimited scalability. Next in line comes the private cloud. Private cloud, popularly known as internal or corporate cloud, is used to host resources that are used exclusively by a single business or an organization. With private cloud, users get additional control, security, and privacy as people outside your organization would not be able to access resources hosted in private cloud. One of the major drawbacks of private cloud is that private cloud requires almost similar staffing, management and maintenance expenses as incurred with traditional data centers because the company's IT department is responsible for managing the cloud. Finally, we have hybrid cloud. Hybrid cloud is a combination of both public and private cloud. It is a cloud computing environment that combines an on-premise data center, also called US private cloud with public cloud allowing data and applications to be shared between them. When computing and processing demands fluctuate, hybrid cloud computing model gives businesses the flexibility to use new cloud first technologies for their new workloads while still keeping their business critical applications and data on premise. Hybrid cloud model is best suited for industries such as banking, finance, healthcare, et cetera, that deal with highly sensitive data and need the data to be kept on premises while still wanting to leverage the advantages of cloud. Let's analyze all of the cloud deployment models in a class. There are several factors that come into picture while choosing a cloud deployment model: Initial setup, scalability, cost optimization, reliability, data security, and privacy are some of the major factors that you have to consider while choosing a cloud deployment model for your organization. It is important to understand that there is no one type of cloud which fits everyone's requirements. Choice of cloud computing model depends on your business needs.
