I have a Standard reserved instance for almost 7 months now and planning to switch the Standard reserved to convertible RI, In the beginning i have signed up for 3 years contract, if i convert the standard RI to Convertible now (after 7 months) will my term will start over again from month 1 or will it continue from month 7.
I'm using a burstable T3 instance on-demand, and thinking about converting to a reserved instance as it would save me quite a lot in the long run. Will Amazon charge me for bursts the same way as with the on-demand instance, and simply add that on top of my monthly dues?
I'm looking at purchasing a reserved instance to access a GPU on AWS. It's likely that a few month down the line i will need to migrate the workload elsewhere.
Can i still see the RI on the marketplace, even if i am only paying for it monthly with no upfront costs, to get out of the agreement?
I have 2 RDS databases size db.t2.medium. I went to AWS recommendations and got this:
So far I've done only EC2 reservations. I am not sure how to proceed from here. First I guess I have to make the reservation on RDS menu for 8 db.t2.micro reserved instances...
And after?
How can I modify existing databases to assign them 4 db.t2.micros to each one?
- I see where to change the instance type.... but I will be replacing one database db.t2.medium with another one db.t2.micro...
- Maybe storage auto-escaling will do the trick?
Should be another easy one here, but I need clarification on what they define as "heavy utilization" for Reserved Instance types. From their Website:
Heavy Utilization RIs – Heavy Utilization RIs offer the most absolute savings of any Reserved Instance type. They’re most appropriate for steady-state workloads where you’re willing to commit to always running these instances in exchange for our lowest hourly usage fee. With this RI, you pay a little higher upfront payment than Medium Utilization RIs, a significantly lower hourly usage fee, and you’re charged that lower hourly rate for every hour in the Reserved Instance term you purchase. Using Heavy Utilization RIs, you can save up to 41% for a 1-year term and 58% for a 3-year term vs. running On-Demand Instances. If you’re trying to find a break-even utilization, you’re economically advantaged using Heavy Utilization RIs (vs. On-Demand Instances) if you plan to use your instance more than 43% of a 1-year term or 79% of a 3-year term.
I'm assuming that, if I'm planning on running a 24/7 Web Server, then regardless of how many resources I consume (bandwidth, cpu cycles, memory), I would want to go with a Heavy Utilization Reserved Instance? This one Web Server in particular will likely barely budge the cpu, but it needs to be up and running 24/7.
Not 100% on what they're defining as "heavy".
