安排在AWS EC2一个作业 [英] Scheduling A Job on AWS EC2
问题描述
我对AWS EC2上运行一个网站。我需要创建一个生成网站地图文件，上传文件到不同的浏览器夜间作业。我正在寻找在AWS上一个实用工具，允许这项功能。我已经考虑了以下内容：
I have a website running on AWS EC2. I need to create a nightly job that generates a sitemap file and uploads the files to the various browsers. I'm looking for a utility on AWS that allows this functionality. I've considered the following:
1）产生一个请求，以触发它做这个任务web服务器
1) Generate a request to the web server that triggers it to do this task
- 我不喜欢这种方法，因为它占用了一个服务器线程和使用的CPU周期的主机上
2）创建的Web服务器上运行来执行这项任务的机器上的cron作业
2) Create a cron job on the machine the web server is running on to execute this task
- 同样，我不喜欢这种方法，因为它需要CPU周期远离Web服务器
3）创建另一个EC2实例，并成立一个cron作业运行的任务
3) Create another EC2 instance and set up a cron job to run the task
- 这解决了Web服务器资源问题，但为什么付出额外的EC2实例为＆LT运行作业5分钟呢？白花钱！
是否还有其他选择吗？这是ElasticMa preduce工作？
Are there any other options? Is this a job for ElasticMapReduce?
推荐答案
亚马逊刚刚发布了[1]弹性青苗的新功能。现在，您可以创建一个包含cron.yaml的配置计划任务调用和cron语法的URL工人环境：<一href="http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/using-features-managing-env-tiers.html#worker-periodictasks">http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/using-features-managing-env-tiers.html#worker-periodictasks
Amazon has just released[1] new features for Elastic Beanstalk. You can now create a worker environment containing cron.yaml that configures scheduling tasks calling an URL with the CRON syntax: http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/using-features-managing-env-tiers.html#worker-periodictasks
