Compute in the Cloud

What is Amazon Elastic Compute Cloud (Amazon EC2) ?

• Amazon Elastic Compute Cloud (Amazon EC2) provides secure, resizable compute capacity in the cloud as Amazon EC2 instances.

• Amazon Elastic Compute Cloud (Amazon EC2) provides on-demand, scalable computing capacity in the Amazon Web Services (AWS) Cloud.

• Ability to run serverless applications.

• AWS management of operating system patches.

What is savings plans?

• Savings Plan offers low prices on EC2 usage in exchange for a commitment to a consistent amount of usage measured in dollars per hour for a one or three-year term.

• Savings Plan offers low prices on EC2 usage in exchange for a commitment to a consistent amount of usage measured in dollars per hour for a one or five-year term.

• Savings Plan offers low prices on EC2 usage in exchange for a commitment to a consistent amount of usage measured in dollars per hour for a one or four-year term.

What is On-Demand?

• You only pay for the duration that your instance runs for. This can be per hour or per second, depending on the instance type and operating system you choose to run. Plus, no long-term commitments or upfront payments are needed.

• You only pay for the duration that your instance runs for. This can be per hour or per second, depending on the instance type and operating system you choose to run. Only six months commitments or upfront payments are needed.

• You only pay for the duration that your instance runs for. This can be per hour or per second, depending on the instance type and operating system you choose to run. Upfront payments are needed.

What are Reserved Instances?

• Reserved Instances are suited for steady-state workloads or ones with predictable usage and offer you up to a 75% discount versus On-Demand pricing. You qualify for a discount once you commit to a one or three-year term.

• Reserved Instances are suited for steady-state workloads or ones with predictable usage and offer you up to a 75% discount versus On-Demand pricing. You qualify for a discount once you commit to a one or six-year term.

• Reserved Instances are suited for steady-state workloads or ones with predictable usage and offer you up to a 75% discount versus On-Demand pricing. You qualify for a discount once you commit to a one or four-year term.

What are Spot Instances?

• Spot Instances, and allow you to request spare Amazon EC2 computing capacity for up to 90% off of the On-Demand price. The catch here is that AWS can reclaim the instance at any time they need it.

• Spot Instances, and allow you to request spare Amazon EC2 computing capacity for up to 80% off of the On-Demand price. The catch here is that AWS can reclaim the instance at any time they need it.

• Spot Instances, and allow you to request spare Amazon EC2 computing capacity for up to 60% off of the On-Demand price. The catch here is that AWS can reclaim the instance at any time they need it.

What is Amazon EC2 Pricing?

• With Amazon EC2, you pay only for the compute time that you use. Amazon EC2 offers a variety of pricing options for different use cases.

• With Amazon EC2, you pay only for the compute time that you use. Amazon EC2 offers four variety of pricing options for different use cases.

• With Amazon EC2, you pay only for the compute time that you use. Amazon EC2 offers five variety of pricing options for different use cases.

What are Dedicated Hosts?

• Dedicated Hosts are physical servers with Amazon EC2 instance capacity that is fully dedicated to your use.

  You can use your existing per-socket, per-core, or per-VM software licenses to help maintain license compliance.

• Dedicated Hosts are virtual servers with Amazon EC2 instance capacity that is fully dedicated to your use.

  You can use your existing per-socket, per-core, or per-VM software licenses to help maintain license compliance.

• Dedicated Hosts are physical backups with Amazon EC2 instance capacity that is fully dedicated to your use.

  You can use your existing per-socket, per-core, or per-VM software licenses to help maintain license compliance.

What is scalability?

• Scalability involves beginning with only the resources you need and designing your architecture to automatically respond to changing demand by scaling out or in.

• Scalability involves beginning with only the resources you need and designing your architecture to automatically to changing demand every year.

• Scalability involves beginning with only the resources you need and designing your architecture to automatically to changing demand every two years.

What is Amazon EC2 Auto Scaling?

• Amazon EC2 Auto Scaling enables you to automatically add or remove Amazon EC2 instances in response to changing application demand.

• Amazon EC2 Auto Scaling enables you to automatically add or remove Amazon Reserved Instances in response to changing application demand.

• Amazon EC2 Auto Scaling enables you to automatically add or remove Amazon Spot Instances in response to changing application demand.
