Q

Security needs vs cloud models

A
  1. maximum control of security => IaaS => provides physical resources but lets manage the operating systems and installed software, including patches and maintenance.
  2. patches and maintenance taken care of automatically => PaaS / SaaS

Q

Management of the cloud

A

managing your cloud resources:

  1. Automatically scale resource deployment based on need.
  2. Deploy resources based on a preconfigured template, removing the need for manual configuration
  3. Monitor the health of resources and automatically replace failing resources.
  4. Receive automatic alerts based on configured metrics, so you’re aware of performance in real time.

Q

IaaS

A
  1. the cloud provider is responsible for maintaining the hardware, network connectivity (to the internet), and physical security.
  2. You’re responsible for everything else: operating system installation, configuration, and maintenance; network configuration; database and storage configuration; installation and configuration, patching and updates, and security.

IaaS - essentially renting the hardware in a cloud datacenter, but what to do with that hardware is up to you.

17
Q

IaaS common scenarios

A
  1. Lift-and-shift migration: You’re standing up cloud resources similar to your on-prem datacenter, and then simply moving the things running on-prem to running on the IaaS infrastructure.
  2. Testing and development: You have established configurations for development and test environments that you need to rapidly replicate. You can stand up or shut down the different environments rapidly with an IaaS structure, while maintaining complete control.
18
Q

PaaS

A
  1. the cloud provider maintains the physical infrastructure, physical security, and connection to the internet.
  2. in addition to IaaS provider also maintain the operating systems, middleware, development tools, and business intelligence services that make up a cloud solution.
  3. don’t have to worry about the licensing or patching for operating systems and databases.
  4. depending on the configuration, you or the cloud provider may be responsible for networking settings and connectivity within your cloud environment, network and application security, and the directory infrastructure.
19
Q

PasS common scenarios

A
  1. Development framework: PaaS provides a framework that developers can build upon to develop or customize cloud-based applications. Cloud features such as scalability, high-availability, and multi-tenant capability are included, reducing the amount of coding that developers must do.
  2. Analytics or business intelligence: Tools provided as a service with PaaS allow organizations to analyze and mine their data, finding insights and patterns and predicting outcomes to improve forecasting, product design decisions, investment returns, and other business decisions.
20
Q

SaaS

A

essentially renting or using a fully developed application
Example: Email, financial software, messaging applications, and connectivity software.

21
Q

SaaS common scenarios

A
  1. Email and messaging.
  2. Business productivity applications.
  3. Finance and expense tracking.
