- 1Shared Responsibility Model Solution to well managed security. Diff service models influence ways in which responsibilities are shared among customers.Creates a secure and compliant computing environment in Azure cloud.
- 2IaaS - Renting servers, VM's, storage, networks and operating systems - Most flexible, gives control over hardwareAdvantages
- Flexibility; control to configure & manage hardware running applications
- Skills; no need for technical, can use cloud provider to ensure workloads are secure, safe & highly available - 3- Agility; applications accessible quickly & deprovisioned where needed - Management; user manages & maintain services, cloud provider manages & maintains cloud infrastructure (shared responsibility model) - OpEx modelExample; In Azure rapid deployment of new compute devices (VM's)
Cloud provider keeps hardware up to date, operating system maintenance & network configuration up to cloud tenant. - 4PaaS - Managed hosting environment - Cloud provider manages VM's & networking resources, cloud tenant deploys applications into the managed hosting environmentExample;
Azure App services; developers upload web applications without worrying about physical & software requirements - 5Advantages - Productivity; Platform can be accessed globally, good for distributed teams. Users focus on application development, cloud provider handles platform management.Cloud benefits; access to more cutting edge development tools, can be applied across applications lifecycle.
- Agility; more agile than IaaS, users don't configure servers for running applications - 6- No technical skills - OpEx model Disadvantage - Platform Limitations; can affect how an application runsSaaS
- Cloud provider manages all aspects of application environment (VM's, networking, data storage & applications). Cloud tenant only provides data to the application - 7- Centrally hosted & managed, usually uses one version of application for customers Example; Microsoft 365 provides working version of Microsoft Office that runs in the cloudAdvantages
- PAYG pricing model; users pay for software on subscription model
- Agility; Users can provide staff with latest software quickly & easily - 8- Flexibility; Users can access same application data from anywhere - Skills; no technical skills - no CapExDisadvantage
_ Software Limitations; might affect how users work, don't have direct control of features - 9Server less Computing This allows developers to build applications faster as the cloud service provider manages the infrastructure required to run the code.- Similar to PaaS
- Highly scalable & event driven. Only use resources when triggered
- Helps businesses be more productive & focus on innovation
