A company is launching an ecommerce application that must always be available. The application will run on Amazon EC2 instances continuously for the next
12 months.
What is the MOST cost-effective instance purchasing option that meets these requirements?
For an application that must always be available and is expected to run continuously for 12 months, the most cost-effective instance purchasing option is Savings Plans. Savings Plans offer significant discounts compared to On-Demand Instances by committing to a consistent amount of compute usage over a specified period, typically 1 or 3 years. This option provides flexibility and substantial cost savings, making it ideal for predictable and long-term workloads.
Amazon EC2 Savings Plans enable you to reduce your compute costs by committing to a consistent amount of compute usage for a 1-year or 3-year term. This results in savings of up to 72% over On-Demand Instance costs. Any usage up to the commitment is charged at the discounted Savings Plan rate (for example, $10 an hour). Any usage beyond the commitment is charged at regular On-Demand Instance rates.
what the difference between Saving and Reserved ?
saving plans -- the absence of "reserved instances" in options makes this choice an easy one.
Commitment focus Reserved Instances are built on the commitment to utilize an instance at a specific price over a specific term. Whereas, Savings Plans are built on the commitment to spend a specified dollar amount per hour over a defined period. you can check this link for more details: https://www.nops.io/blog/aws-savings-plan-vs-reserved-instances/
Esse tipo de plano oferece um desconto significativo em relação ao plano sob demanda. Possui vigência de 1 a 3 anos e é ideal para quando sabemos a carga necessária, como o caso. Por outro lado, não pode ser o spot pois a aplicação precisa ficar sempre disponível.
I looked for Reserved Instances. Among the options, the Saving Plans makes the most sense.
Savings Plans are a flexible and cost-effective pricing model offered by AWS. By purchasing Savings Plans, the company can commit to a specific amount of compute usage (measured in dollars per hour) over a one- or three-year term. This allows them to receive significant discounts on their EC2 instance usage compared to On-Demand Instances. Savings Plans provide flexibility in terms of instance type, family, region, and operating system. They apply to EC2 usage regardless of instance size or availability zone, giving the company the freedom to choose the instances that best meet their application requirements.
correct answer
If it was `AWS Partner Network (APN)` B could be another correct answer. There is no service or feature named as `AWS Consulting Partners` so I would not select B. `AWS Managed Services` is the answer and it helps the companies with the migration. https://aws.amazon.com/managed-services/
D. Las instancias bajo demanda son la opción más rentable para ejecutar una aplicación nueva de la cual no conocemos sus requerimientos en el futuro.
B is the suitable in listed.
saving plan is best suited for this. B is Correct
