Secure Access Service Edge is a cloud computing service. Hence, delivers a wide area of network and security controls to the point of connection rather than a data center. Digital identification, real-time context, and organizational and regulatory compliance standards all contribute to security.
What is cloud computing?
Cloud computing is the delivery of computing services over the Internet. Allowing you to use applications, storage, and processing resources as you need them. The three basic forms of cloud computing are Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).
Infrastructure as a Service (IaaS)
Infrastructure as a Service (IaaS) is the ability to deploy virtual resources into an on-demand environment. IaaS is also what we know as virtualization. This form of cloud computing allows you to create, manage, and process infrastructure components. Such as servers, storage, networks, and applications in an on-demand environment. We can also use IaaS to deploy server workloads. Further, that provides scalability and flexibility by leveraging the elasticity characteristics of the cloud. To provision IaaS resources in Windows Azure.
Platform as a Service (PaaS)
Platform as a Service (PaaS) is a type of cloud computing service. Hence, that lets clients avail, establish, run, and handle a modular bundle. Further, that includes a computing platform and one or more applications. Even without the burden of managing the facilities usually associated with creating and initiating the application(s); and enabling people to design, develop, and package such app bundles.
Software as a Service (SaaS)
Software as a Service (SaaS) is the delivery of a computing platform and/or application software over the Internet. A SaaS solution can be accessed by users using a thin client via a web browser. Also, a user can use Web 2.0 technologies, such as AJAX, to create rich Internet applications. The user does not manage or control the underlying cloud infrastructure, network, servers, operating systems, or storage. Or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.
SaaS is a model for enabling ubiquitous, convenient, on-demand network access. Further, to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications and services). Also, that can be rapidly provisioned and released with minimal management effort or service provider interaction.
What are the four major characteristics of cloud computing?
Cloud computing has four major characteristics: elasticity, pay-for-use pricing model, self-service provisioning model, and virtualization of resources. elasticity
What is elasticity?
Elasticity is the ability to scale out or in based on demand. So, elasticity allows you to quickly burst additional resources into your cloud infrastructure. Even during peak times while also easily releasing unused cloud services when they are no longer needed. Pay-for-use pricing model
What is a pay-for-use pricing model?
A pay-for-use pricing model allows you to only pay for what you use. And not a flat rate for all resources. Moreover, this pricing model is ideal for organizations that have unpredictable usage patterns throughout the year. And those with large spikes in demand during certain times of the year. Self-service provisioning model
What is a self-service provisioning model?
A self-service provisioning model allows you to quickly deploy new servers into your cloud infrastructure. Also, when needed without having to go through lengthy procurement cycles. Or request approval from someone else in your organization. Virtualization of resources.
What is virtualization?
Virtualization allows you to abstract computer resources. So that they look like real resources but your underlying physical infrastructure can change without impacting applications running on top of them. Further, elasticity allows you to quickly burst additional resources into your cloud infrastructure during peak times. Also easily releasing unused cloud services when they are no longer needed.
