Cloud Concepts

Question 1

High availability

Answer 1

Refers to a set of technologies that minimize IT disruptions by providing business continuity of IT services through redundant, fault-tolerant, or failover-protected components inside the same data center. In our case, the data center resides within one Azure region

Question 2

Fault tolerance

Answer 2

Fault tolerance is a process that enables an operating system to respond to a failure in hardware or software. This fault-tolerance definition refers to the system’s ability to continue operating despite failures or malfunctions.

Question 3

Disaster recovery

Answer 3

Disaster recovery is the process of restoring application functionality in the wake of a catastrophic loss. In the cloud, we acknowledge up front that failures will happen. Instead of trying to prevent failures altogether, the goal is to minimize the effects of a single failing component.

Question 4

Scalability

Answer 4

Scalability is the ability of a system to handle increased load. Services covered by Azure Autoscale can scale automatically to match demand to accommodate workload. They will scale out to ensure capacity during workload peaks and scaling will return to normal automatically when the peak drops.

Question 5

Elasticity

Answer 5

Elasticity is the ability to fit the resources needed to cope with loads dynamically usually in relation to scale out

Question 6

Agility

Answer 6

The ability to rapidly develop, test and launch software applications that drive business growth
