Module 1 Flashcards
What are the Cloud Components
Servers Storage Database Network Software Analytics and intelligence
What are the benefits of Cloud.Describe each Benefit
Cost - eliminates capital costs
Speed. Can provision in minutes
Global Scale. Ability to Scale elastically. More or less computing power,storage, bandwidth right when it is needed;
Performance: Run on world wide network of data centers which are regularly upgraded to fat and efficient hardware
Security: broad set of security controls to protect
Productivity: no more racking and stacking, hardware setup software patching
Reliability: Makes backups and disaster recovery easier and less expensive. Data is mirror to multiple sites
What component is allows creation of users and groups in the cloud
Azure AD
What are the 3 types of Cloud platforms
IAAS,PAAS and SAAS
Describe IAAS
Renting of Servers and virtual machines, Storage and Operating systems.
Describe PAAS
Provides on demand taylormade environments for developing, testing, delivering and managing software applications.
What group is most like to use PAAS
Developers are most likely to use PAAS. it eases the burden of having to configuring operating systems,storage etc so they cna get directly to developing
Describe SAAS
Delivering software over the internet on a subscription basis.
Types of Cloud
Public., Private, Hybrid
Describe Hybrid Cloud
connects one or more public or private clouds. Generally used for transition or to meet security requirements
Describe Hybrid Cloud
connects one or more public or private clouds. Generally used for transition or to meet security requirements
Public Cloud Pros and Cons
Advantages: Highly scalable Pay as you go not responsiable for maintence or updates fo hardware minimal technical knowledge
Disadvantages:
May be issues meeting specifica security requirements
Government or industry/legal standards may not be able to be met
You do not own the hardware or services and give up management control
Hybrid Cloud Pros and Cons
Advantages
You can keep any systems running and accessible that use out of date hardware or operating systems
You have flexibility with what is run locally versus the cloud
You can take advantage of economies of scale
Disadvantages
It can be more expensive then selecting one deployment and involves some Capex
It is more complicated to setup and manage
Private Cloud Pros and Cons
Advantages:
Ensure the configuration and support any scenario or legacy application.
You have control and responsibility over security.
Private clouds can meet strict security, compliance or legal requirements
Economies at scale and integration with Azure Security center
Disadvantages:
Capex, you must purchased all hardware and maintain it
Owning equipment limits agility, you must spend money to expand install , setup new
Require skilled IT personnel that is hard to come by
IAAS know for the exam
Infrastructure as a service (laaS)
laaS is the most flexible category of cloud services.
It gives you complete control over the hardware that runs your
application (IT infrastructure servers and virtual machines (VMS),
storage, networks, and operating systems). Instead of buying
hardware, with laaS, you rent it.
It’s an instant computing infrastructure, provisioned and managed
over the internet.
laaS is commonly used in the following scenarios
‘Migrating workloads
‘Test and development
OStorage, backup, and recovery
