Q

An organization has multiple AWS accounts and uses a mixture of on-demand and reserved instances. One account has a considerable amount of unused reserved instances. How can the organization reduce their costs? (choose 2)

  1. Redeem their reserved instances
  2. Use Spot instances instead
  3. Create an AWS Organization configuration linking the accounts
  4. Switch to using placement groups
  5. Setup consolidated billing between the accounts
A
  1. Create an AWS Organization configuration linking the accounts
  2. Setup consolidated billing between the accounts
  • AWS organizations allow you to consolidate multiple AWS accounts into an organization that you create and centrally manage. Unused reserved instances (RIs) for EC2 are applied across the group so the organization can utilize their unused reserved instance instead of consuming on-demand instances which will lower their costs
  • You cannot redeem your reserved instances. You can sell them on the AWS marketplace however
  • Using placement groups will not lower their costs
  • Spot instance pricing is variable so it is not guaranteed to lower the cost and it is not suitable for workloads that cannot be unexpectedly terminated by AWS

  5. Reserved instances for applications with flexible start and end times
A
  1. On-demand for ad-hoc requirements that cannot be interrupted
  2. Reserved instances for steady state predictable usage
  • Typical use cases for the pricing models listed are:
  • On-demand: Good for users that want the low cost and flexibility of EC2 without any up-front payment or long-term commitment. Applications with short term, spiky, or unpredictable workloads that cannot be interrupted
  • Reserved: Applications with steady state or predictable usage or that require reserved capacity
  • Spot: Applications that have flexible start and end times and that are only feasible at very low compute prices. May be terminated
  • Dedicated hosts: Useful for regulatory requirements that may not support multi-tenant virtualization. Great for licensing which does not support multi-tenancy or cloud deployments
43
Q

A company wants to utilize a pay as you go cloud model for all of their applications without CAPEX costs and which is highly elastic. Which cloud delivery model will suit them best?

  1. Public
  2. Private
  3. Hybrid
  4. On-premise
A
  1. Public
