A major broadcasting company that requires continuous availability to streaming content needs to be resilient against DDoS attacks. Which of the following Is the MOST important infrastructure security design element to prevent an outage?
A.
Supporting heterogeneous architecture
B.
Leveraging content delivery network across multiple regions
C.
Ensuring cloud autoscaling is in place
D.
Scaling horizontally to handle increases in traffic
B. Leveraging content delivery network across multiple regions.
A content delivery network (CDN) is a network of servers distributed around the world that deliver content to users based on their geographic location. This can help to improve performance and reduce latency, but it can also help to mitigate DDoS attacks by distributing the traffic across multiple servers.
To specifically defend against DDoS attacks and ensure continuous availability to streaming content, the most direct and effective infrastructure security design element would be:
B. Leveraging content delivery network (CDN) across multiple regions.
B. Leveraging content delivery network across multiple regions
To prevent an outage due to DDoS attacks, leveraging a content delivery network (CDN) across multiple regions is the most important infrastructure security design element. Here's why:
DDoS Mitigation: A CDN can distribute traffic across multiple servers and data centers, making it more resilient to DDoS attacks. It can absorb and mitigate the impact of a large-scale attack by distributing the load.
Geographic Redundancy: By utilizing multiple regions, even if one region experiences a DDoS attack, the content delivery can be maintained from other regions, ensuring continuous availability.
