You manage a Ruby on Rails application that lives on a cluster of EC2 instances. Your website occasionally experiences brief, st

rong, and entirely unpredictable spikes in traffic that overwhelm your EC2 instances' resources and freeze the application. As a result, you're losing recently submitted requests from end users. You use Auto Scaling to deploy additional resources to handle the load during spikes, but the new instances don't spin-up fast enough to prevent the existing application servers from freezing. Which of the following will provide the most cost-effective solution in preventing the loss of recently submitted requests?
A. Keep a large EC2 instance on standby.
B. Increase the size of your existing EC2 instances.
C. Ask AWS support to pre-warm the Elastic Load Balancer.
D. Use Amazon SQS to decouple the application components and keep the requests in queue until the extra Auto-Scaling instances are available."

Discuss how the user-designer communications gap can cause a good project to go bad.
Mila [183]
This gap between user-designer communications <span>can cause a good project to go bad i</span>f the user is not able to process what is required to be fixed in order for the project to run smoothly. The user may have one way of fixing something while the designer has another. In this case, the designer understands how the project fully works while the user does not and this may end up compromising the whole project.

The law that “designers are not users” and “users are not designers” should always be followed.

Complete the steps to evaluate the following
kirill115 [55]

Answer:

log base 3a= -0.631.log a/3 base 3

Now, -log m= log 1/m

hence,

log base 3a= 0.631.log 3/a base 3

log base 3a/log 3/a base 3 =0.631

log base 3 ( a.3/a) =.631 since, log m/logn =log n(m)

log base 3 3=0.631

Hence, answer is log base 3 3=0.631
