The only thing I can figure is a) he wants to schedule a script or b) an instance will be powered off normally, but he wants it to come on at a specific time.

Which is weird. You pay even if it’s off. So just bring up instances when you need them.

Right I read a post the other day someplace where the OP was wanting to turn off Azure servers after hours. You still pay for those until they are destroyed.

But the OP in that thread mentioned something about some agreement you can get that you pay less for powered off servers.

I wonder what the use case is for that vs just bring them up when you need them?

Automatically creating/destroying cloud instances on an as-needed basis would be a great thing to automate, actually.

Ya here's a sample:

---
- name: create aws instances
  hosts: localhost

  tasks:
    - name: create ec2 instance
      ec2:
        key_name: centos
        instance_type: t2.micro
        image: ami-ae7bfdb8
        wait: yes
        group: dns
        count: 1
        instance_tags:
          type: dns
        region: us-east-1
      register: ec2

    - name: wait for SSH
      wait_for:
        host: "{{ item.public_dns_name }}"
        port: 22
        delay: 30
        timeout: 320
        state: started
      with_items: "{{ ec2.instances }}"

Creating and destroying is not turning on and off.

Right, turning on and off doesn't make much sense. Just create destroy as needed.

May be he is looking for something like https://aws.amazon.com/answers/infrastructure-management/ec2-scheduler/

I don't get that. It seems less flexible than an ELB and you would have to continually calculate what you would need. Why not just pay for the ELB and have it automatically do this?

If you really don't need this type of infrastructure, then just use something like Vultr or DO.

I'm gonna have to read up on the ELB. Looks like exactly the thing I've been wondering why nobody had.

Ya they're pretty awesome. You need to use their monitoring to get the most out of it, but if you are operating at that scale it's worth it anyway.

Hi, I need to configure every day the server need to be powered on automatically some time and the same need to be powered off in the evening. Power off i was done through scheduled task in windows. But powering on is the challenge. I tried with lambda option but having some error

This really just rephrasing the OP. What is this server doing?

bigbear

It would make sense for an app running on another Amazon Virtual Machine as @travisdh1 particularly in telecom where you create and destroy servers on the fly to handle call bursts, or to just eliminate a dorked server that is having trouble.

Turning on and off though, probably he is after something else.

However, as awesome as it is you have to take into account the vendor lock in you are accepting. Chances are you won’t just be able to migrate to another provider if you need to without significant retooling.

Instead of turning the server on and off, might it make sense to just turn the service on and off?

Are you trying to save some money on the amount of hours the server is powered on a month?

Here I thought that was the whole point of using things like EC2.

Best that you found out now. It's a common misconception that it is about "powered on" versus "existing." The point of cloud computing is creating / destroying to save money, not powering on and off. The later we could do before cloud.

Yes, I'm very aware of this, which is why I brought up the automated create/destroy so much earlier in this thread!
