Hey I just want to know info about the reserved rds instance. Suppose one purchase an reserve rds plan for an year with no up front payment method. And there is no rds instance currently running that matches the same setting like db instance class etc as of the reserved one. Will I am going to charge for it or not, as reserve rds plan is of 1 year.
Thanks
Yes. With reserved instances you pay for it, if you use it or not.

One of my reserved instance is about to expire in near futre.
I'd like to buy the reserved plan for the instance
(I'm not planning to run 2 such instances at the same time)
I just want to extend the reserved period if it makes sense.
How do I do that?
feels like this might be very good fit for stackoverflow, please let me know if there's a better qna site for this.
From Learn How to Renew an EC2 Reserved Instance:
You can queue your Reserved Instance purchases for a specific date and time in the future. To renew your EC2 RI automatically, you can queue an RI purchase for the date and time that your existing RI expires. On the scheduled date and time, AWS automatically purchases the RI for you using your account's default payment method.
Before renewing, I would suggest you also consider AWS Savings Plans, which are more flexible than Reserved Instances. Also, consider whether you want a 1-year term or a 3-year term and, for RIs, whether it is Zonal or Regional.
I lunched a reserved instance for RDS yesterday. I waited for the billing to be updated till today morning (it takes normally 6 hours to a day). Now when I go to the Billing the reserved instance and on-demand instance, both are active and being charged. I was hoping once I created the reserved instance of same instance type, AZ, Tenancy the reserved instance would apply to the on-demand instance.
My on-demand aurora mysql instance look like this:

My Billing overview:
======== Edit
Apparently, It takes 24 hours to takes RI to take effect so that on demand instance can use it. There was nothing wrong with what I've done... just needed some time.
How do i terminate and delete a RDS Instance that is on Amazon Web services . I successfully deleted the rds instance ystd, however it is still incurring charges on me. is it possible that I deleted it wrongly?
If you see charges even after you deleted an RDS instance, make sure:
That you didn't reserved a particular instance type ( see here for more details https://aws.amazon.com/rds/pricing/ )
That you are checking the right region. ( On the UI right top corner, click through them and check if you don't have instances in other regions ).
If something still not clear contact aws support. They are usually pretty good at responding and helping you troubleshoot issues.
One thing to remember is that AWS bills on a monthly basis.
Unless you purchased a reserved instance of some type upfront (which is possible for RDS) you will incur a charge at the end of the month for the actual usage of the instance over the monthly billing period, even if you used it for just a few minutes.
I have little query related to reserved c3.large going to 1 year and it was reserved for 1 year does it will renew automatically or i need to do it manually.
If yes please advise how i can do it.
You don't actually 'renew' a reserved instance - you buy another one. Remember a reserved instance is just a billing construct and has nothing to do with any particular instance that may or may not be running.
So when the term of the reserved instance runs out, any instances you have simply start getting billed at the on-demand rate, unless and until you purchase another reserved instance.
You have to do it manually. From: Reserved Instances
Reserved instances do not renew automatically; you can continue using the EC2 instance without interruption, but you will be charged
On-Demand rates.
The other answers here are correct, but for my use case the easiest thing was to let the instance expire and then "Purchase More Like These". See details here.
We’ve purchased an Amazon Web Services (AWS) reserved instance for an Amazon Elastic Compute Cloud (EC2) instance that is critical to our infrastructure. This instance starts and stops every day at certain time interval.
I see that purchasing a reserved instance 'guarantees' that this instance will reliably start even when AWS is under heavy load, but is there any way to specifically tie this reserved instance to the instance we want to associate with it?
What happens if we add another instance that matches the exact criteria of the reserved instance we’ve purchased?
You don't need to worry or do anything in associating the instance and the purchased Reserved Instance; all those are done automatically by AWS.
The reserved Instance is purely a billing and cost related and it doesn't relate to the technology aspect of an EC2 instance. If any of your running instance matches with any of your purchased Reserved Instance then you benefit from the reduced costing. There isn't any commitment on the SLA or changes at the Instance level which involves Reserved Instance. The same case works when you have 2 reserved instances; if there 2 instances running in your account which matches your reserved instance purchase they the reduced cost would be applied.
Analogy - Super Market Coupon Offer
If the Offer Says, buy 2 units of Product A and get one Product B
absolutely Free. So you look into the offer and take 2 units of
Product A and one Unit of Product B. During the billing as well, the
Point of Sales Person also doesn't look into each and every product
and try to check it offers; rather he or she directly keeps scaning
each and every product against the bar-code scanner and that't it -
when these 3 are scanned, the price for Free-Product is automatically
reversed.
So similarly, you buy the Reserved Instance (Coupon) choosing the AMI,
Region, AZ, Duration etc. You would do all your tech stuff as usual
like deploying, patching, monitoring etc. During the billing, if the
instance(s) you launched matches the Reserved Instance, then the
Reserved pricing would be applied; if not that would be charged at
'On-Demand-Pricing'.
If there is a mismatch between what instance you are running and what instance you have reserved; you will not be using the benefit of Reserved-Instance pricing
and be charged with On-Demand-Pricing. Also you will be wasting the
investment done for the Reserved-Instance
As implied in Naveen's answer, there is no direct way to associate an instance with a reservation.
If you want the reliability, then you must launch instances with unique set of properties (instance type, az and AMI). There is no other way at the moment.
This is supposed to be a comment in Naveen's reply. But as I had no reputation yet to commen, I am adding it as an answer.
