Workloaded security models are ways of protecting applications, services, and capabilities that run on a cloud resource. Virtual machines, databases, containers, and applications are all considered cloud workloads. There are different types of cloud deployment models, such as public, private, hybrid, and multicloud. Depending on the deployment model, the cloud workload security can vary in terms of responsibility, visibility, and control.
Infrastructure as a service (IaaS) is a cloud deployment model where the cloud provider offers the basic computing infrastructure, such as servers, storage, and networking, as a service. The customer is responsible for installing, configuring, and managing the operating systems, applications, and security of the workloads that run on the cloud infrastructure. IaaS provides the customer with more flexibility and control over the workload security, but also more complexity and overhead.
On-premises is a deployment model where the customer owns and operates the entire IT infrastructure, including the hardware, software, and security. The customer has full responsibility and control over the workload security, but also the highest cost and maintenance. On-premises deployment can offer more security and compliance than cloud deployment, depending on the customer's security posture and practices.

Explanation Explanation The traditional use of the pull model, where the client requests data from the network does not scale when what you want is near real-time data. Moreover, in some use cases, there is the need to be notified only when some data changes, like interfaces status, protocol neighbors change etc. Model-Driven Telemetry is a new approach for network monitoring in which data is streamed from network devices continuously using a push model and provides near real-time access to operational statistics. Applications can subscribe to specific data items they need, by using standard-based YANG data models over NETCONF-YANG. Cisco IOS XE streaming telemetry allows to push data off of the device to an external collector at a much higher frequency, more efficiently, as well as data on-change streaming.

Explanation Explanation Other features are dependent on SSL Decryption functionality, which requires the Cisco Umbrella root certificate. Having the SSL Decryption feature improves: Custom URL Blocking-Required to block the HTTPS version of a URL. ... Umbrella's Block Page and Block Page Bypass features present an SSL certificate to browsers that make connections to HTTPS sites. This SSL certificate matches the requested site but will be signed by the Cisco Umbrella certificate authority (CA). If the CA is not trusted by your browser, an error page may be displayed. Typical errors include "The security certificate presented by this website was not issued by a trusted certificate authority" (Internet Explorer), "The site's security certificate is not trusted!" (Google Chrome) or "This Connection is Untrusted" (Mozilla Firefox). Although the error page is expected, the message displayed can be confusing and you may wish to prevent it from appearing. To avoid these error pages, install the Cisco Umbrella root certificate into your browser or the browsers of your users-if you're a network admin.
