What is Multivalue routing? | ContextResponse.com

what is failover routing? Failover routing lets you route traffic to a resource when the resource is healthy or to a different resource when the first resource is unhealthy. The primary and secondary records can route traffic to anything from an Amazon S3 bucket that is configured as a website to a complex tree of records.

Subsequently, one may also ask, what is weighted routing?

Weighted Routing Policy Weighted routing policy enables Route 53 to route traffic to different resources in specified proportions (weights) for e.g., 75% one server and 25% to the other during a pilot release. Weights can be assigned any number from 0 to 255.

Why is failover important?

Failover is an important fault tolerance function of mission-critical systems that rely on constant accessibility. Failover automatically and transparently to the user redirects requests from the failed or down system to the backup system that mimics the operations of the primary system.

What is the difference between failover and failback?

Failover and failback operations. The failover operation is the process of switching production to a backup facility (normally your recovery site). A failback operation is the process of returning production to its original location after a disaster or a scheduled maintenance period.

How does a DNS server work?

It is, in short, a system of matching names with numbers. The DNS concept is like a phone book for the internet. Instead, you just connect through a domain name server, also called a DNS server or name server, which manages a massive database that maps domain names to IP addresses.

How are Reserved Instances different from On Demand DB Instances?

The only difference between the two is that a Reserved Instance is one you rent (“reserve”) for a fixed duration, and in return you receive a discount on the base price of an On Demand instance. Standard Reserved Instances lock you into using one instance family, on the same operating system.
