I found DevPay & FPS in the documentation, but they don't seem to apply to my account, but rather my customers'. I'd hate to scrape the account screen , but I'll do it, if needed. 回答1: You can't, unfortunately neither AWS nor any other IaaS/PaaS/SaaS vendor I'm aware of does offer API access to their accounting data currently (maybe due to the potential financial/legal implications) - see my longer answer on How can I monitor daily spending on AWS? for an interesting alternative

I read through various articles regarding providing appropriate permissions for mysql to be accessed from external IP addresses, and here are the steps that I followed: Opened port 3306 on my host EC2 instance to allow for external Mysql connection. In the file /etc/mysql/my.cnf, changed the "bind-address" from "127.0.0.1" to "0.0.0.0". Opened mysql using root, and executed the following command: GRANT ALL PRIVILEGES on . to worker@'ec2

However in terms of costs, if using EC2 it probably requires EBS volumes attached to the EC2 instances, whereas AWS just streams in data from S3. So crunching the numbers on the AWS calculator, even though for EMR one must pay for EC2 also, EMR becomes cheaper than EC2 ?? Am i wrong here ? Of course EC2 with EBS is probably faster, but is it worth the cost ? thanks, Matt 回答1: EMR does a lot of things for you that you won't find on standard Hadoop on EC2. Some particularly important

I am running Sinatra on the machine on port 4567 (currently), and have opened that port in my security group to whole world.

One thing I got from the description is that if we are using this service we don't have to pay for the certificate anymore. They are providing certificates for Elastic Load Balancer (ELB) and CloudFront, but I didn't find EC2 anywhere. Is there any way to use the certificate with EC2? 回答1: Q: Can I use certificates on Amazon EC2 instances or on my own servers? No. At this time, certificates provided by ACM can only be used with specific AWS services. Q: With which AWS services can
