You have a periodic image analysis application that gets some files in input, analyzes them and
for each file writes some data in output to a text file. The number of files in input per day is high
and concentrated in a few hours of the day.
Currently you have a server on EC2 with a large EBS volume that hosts the input data and the
results. It takes almost 20 hours per day to complete the process.
What services could be used to reduce the elaboration time and improve the availability of the
solution?
A.
S3 to store I/O files, SQS to distribute elaboration commands to a group of hosts working in
parallel, Auto Scaling to dynamically size the group of hosts depending on the length of the SQS
queue.
B.
S3 to store I/O files, SNS to distribute elaboration commands to a group of hosts working in
parallel, Auto Scaling to dynamically size the group of hosts depending on the number of SNS
notifications.
C.
EBS with Provisioned IOPS (PIOPS) to store I/O files, SNS to distribute elaboration commands to
a group of hosts working in parallel, Auto Scaling to dynamically size the group of hosts
depending on the number of SNS notifications.
D.
EBS with Provisioned IOPS (PIOPS) to store I/O files, SQS to distribute elaboration commands to
a group of hosts working in parallel. Auto Scaling to dynamically size the group of hosts
depending on the length of the SQS queue.
