SAP on AWS Pricing Fundamentals - General SAP Guides

SAP on AWS Pricing Fundamentals

AWS currently offers over 165 different products and services. The following is an overview of the pricing characteristics for the AWS services that are most relevant for the deployment and operation of SAP systems on AWS.

AWS Region Pricing

AWS service pricing varies between different AWS Regions. The first step in estimating any SAP environment on AWS is to select which AWS Region you will deploy your SAP environment in.

Compute Pricing

Instances

Amazon Elastic Compute Cloud (Amazon EC2) provides a wide selection of instance types that provide varying combinations of CPU, memory, storage, I/O, and networking capabilities. You are charged by the hour for each running instance. The hourly fee of an instance is based on a combination of the following characteristics:

  • Instance type – Specific virtual machine and bare metal configurations that offer different CPU, memory, storage, I/O, and networking capabilities. For more information about Amazon EC2 instance types, see Amazon EC2 Instance Types.

  • Operating system – You can choose to buy an operating system license from AWS or bring your own operating system license or subscription. If you choose to buy the operating system license from AWS, the license fee is included in the EC2 instance fees. For more information, see SAP on AWS Overview and Planning.

  • Monitoring – You can use Amazon CloudWatch to monitor your Amazon EC2 instances. Basic monitoring is included in the hourly cost of an instance and provides metrics at five-minute intervals. For an additional cost, you can use detailed monitoring, which provides metrics at one-minute intervals. Detailed monitoring is required for production SAP systems on AWS. For more information about Amazon CloudWatch pricing, see Amazon CloudWatch pricing.

  • I/O throughput – Amazon EC2 instance types offer different levels of I/O throughput. For production SAP systems, either Amazon Elastic Block Store (Amazon EBS)-optimized instances or instances with 10 gigabit network connectivity are recommended. For more information about Amazon EBS-optimized instances and instances with 10 gigabit network connectivity, see Amazon EC2 Instance Configuration.

Purchasing Options

Amazon EC2 offers multiple purchasing options that give you flexibility to optimize your costs. The On-Demand, Reserved Instance, and Dedicated Host purchasing options are most appropriate for SAP systems.

On-Demand

With the On-Demand option, you pay for compute capacity by the hour with no long-term commitments or upfront payments. You can increase or decrease your compute capacity depending on the demands of your application, and pay only the specified hourly rate for the instances you use.

Recommended for:

  • Initial purchasing option for SAP on AWS projects

  • Temporary SAP systems for testing, upgrades, trials, demos, and proof of concepts (POCs)

  • Temporary SAP systems for scaling to handle increased load

Reserved Instances

The Reserved Instance purchasing option provides you with a significant discount (up to 75%) compared to On-Demand instance pricing. In addition, when Reserved Instances are assigned to a specific Availability Zone, they provide a capacity reservation, which enables you to launch instances when you need them.

For applications that have steady state or predictable usage, Reserved Instances can provide significant savings compared to On-Demand Instances. For more information, see How to Purchase Reserved Instances.

Recommended for:

  • Permanent SAP systems such as production, quality assurance, and development systems

  • Consider for any SAP system that will be online more than 60% of the time.

Dedicated Hosts

A Dedicated Host is a physical Amazon EC2 server dedicated for your use. Dedicated Hosts enable you to use your existing server-bound software licenses, including Windows Server and SQL Server.

Note

Dedicated Hosts are required for Amazon EC2 High Memory instances (6 TB, 9 TB, and 12 TB of memory) and Amazon EC2 bare metal instances.

For more information about Amazon EC2 purchasing options, see Amazon EC2 Pricing.

Storage Pricing

AWS provides flexible, cost-effective, and easy-to-use data storage options for your SAP systems. Each option has a unique combination of performance and durability. This section provides an overview of the primary components of AWS storage pricing.

Primary Storage

Amazon Elastic Block Store (Amazon EBS) provides persistent, block-level storage volumes for SAP systems that run on Amazon EC2. Each SAP Amazon EC2 system requires one or more Amazon EBS volumes to store system components, such as the operating system, SAP software, SAP database data and log files, and local backup storage. For information about Amazon EBS pricing, see Amazon EBS Pricing.

Backup Storage

Multiple options are available to back up your SAP system on AWS. For an overview of options, see SAP on AWS Backup and Recovery Guide. Each option stores backup files in Amazon Simple Storage Service (Amazon S3) to provide highly durable storage that is independent of primary storage. For information about Amazon S3 pricing, see Amazon S3 Pricing.

The amount of backup storage required depends on the backup method, backup frequency, system size, and backup retention. How to calculate the amount of backup storage you require is not included in this guide.

Network Pricing

Amazon VPC Connectivity

There is no additional cost for using Amazon Virtual Private Cloud (Amazon VPC) over the standard Amazon EC2 usage charges. If a secure connection is required between your on-premises network and Amazon VPC, you can choose one of the following connectivity options.

Hardware VPN Connection

When you use hardware VPN connections to your Amazon VPC, you are charged for each VPN Connection-hour that your VPN connection is provisioned and available. For more information about hardware VPN connection pricing, see Amazon VPC pricing.

Private Network Connection

With AWS Direct Connect, you can make a dedicated network connection from your on-premises network to AWS. AWS Direct Connect is billed by port hours and outbound data transfer rate. For more information about AWS Direct Connect pricing, see AWS Direct Connect pricing.

Data Transfer

There is no charge for inbound data transfer to Amazon EC2. Charges do apply for data that is transferred out from Amazon EC2 to the internet, to another AWS Region, or to another Availability Zone. For details on AWS data transfer pricing, see the On-Demand section of the Amazon EC2 Pricing page.

AWS Support Pricing

AWS offers different levels of support, so you can choose the right level of support for your environment. AWS Basic support is included with all AWS services at no additional cost. If you require a deeper level of support, you can subscribe to Developer, Business, or Enterprise-level support. For more information about the different AWS support plans and pricing details, see AWS Support.
