Zorluk: OrtaHigh Availability, Scalability, and Elasticity

Is the following statement true or false?

Deploying a web application across multiple Azure Availability Zones to protect against localized data center outages achieves high availability, while configuring an autoscale rule to dynamically add virtual machine instances when application traffic increases achieves elasticity.

Cevap: Cevap

Cevap

True
The statement is true because deploying across Availability Zones mitigates localized physical failures, ensuring service continuity (high availability), while configuring autoscale rules dynamically adjusts the count of virtual machines in response to load variations (elasticity).

Adım Adım Çözüm

1
Analyze the first clause regarding deploying a web application across multiple Azure Availability Zones.
Deploying across multiple zones ensures that if a single zone experiences an outage, the application remains operational in other zones. This redundancy directly provides high availability.
To determine if the high availability concept is correctly defined by zone distribution.
2
Analyze the second clause regarding configuring an autoscale rule to dynamically add instances as traffic increases.
Autoscale rules allow compute resources to scale out (and scale in) automatically based on real-time application load. This automatic and dynamic allocation of resources defines elasticity.
To determine if the elasticity concept is correctly defined by dynamic autoscaling.
3
Evaluate the combined statement to determine its truth value.
Both clauses are accurate mappings of their respective cloud concepts, making the overall statement true.
To synthesize the findings and select the correct answer.
