Introduction The sizing and design of a SAP Business One Cloud Landscape is influenced by: Microsoft technical sizing guidelines SAP Business One specific sizing guidelines Sizing a SAP Business One Cloud Landscape is not an EXACT science! It is influenced by: Number of customers Number of users per customer User concurrency SAP Business One Cloud Extensions Transaction volumes, Etc. 2013 SAP AG. All rights reserved. 3
Sizing the hardware required for the Microsoft components Microsoft Windows Server 2008 R2 Active Directory Services RAM required per concurrent user 1MB 1000 concurrent users per CPU core Microsoft Remote Desktop Services: Remote Desktop Gateway RAM required per concurrent user 0.7MB ~300 (or better) concurrent users per CPU core Remote Desktop Connection Broker Remote Desktop Session Host(s) RAM required by OS 2GB Microsoft SQL Server Microsoft SQL Server Instance RAM required by OS 2GB 2013 SAP AG.

Sizing the hardware required for the SAP Business One components SAP Business One SQL Instance for a Service Unit Contains both Common and Tenant databases Typically a SQL instance is limited by CPU processing power rather RAM when it comes to SAP Business One, CPU cores could be estimated to around 20-25 users per core but monitor in your active environments RAM required per concurrent tenant database 2GB RAM required per concurrent tenant database for reporting 0.5GB (this figure can vary, and can be adapted according to experience) SAP Business One extensions could impact on SQL Server CPU and memory requirements and should be considered in sizing SAP Business One SQL Instance for System Landscape Directory Lightweight access, low requirement for processing power/ram beyond standard SQL recommendations If you have multiple SQL instances on a server ensure you consider the combined requirements! 2013 SAP AG.

Sizing the hardware required for the SAP Business One components SAP Business One Client 8 concurrent SAP Business One users per CPU core RAM required per concurrent SAP Business one user 300MB SAP Business One Extensions (Add-ons) SAP Business One Cloud extensions could impact on SQL and Presentation Server CPU and memory requirements and should be considered in sizing Each one will be different and should be checked with the developer SAP Business One Integration Framework If standard scenarios (e.g. Mobile and Dashboards) are being used monitor the server that the B1i is installed on to check any performance impact If additional developed scenarios are used that are higher in intensity the recommended approach is to install the B1i on a separate server (per Service Unit) 2013 SAP AG.

Sizing the hardware required for the SAP Business One components SAP Business One Cloud Storage Storage will vary greatly by customer and their line of business Average tenant database (on-premise/cloud) size reported by SAP is 5GB Need to consider any space used in shared folders Need to consider space required for backups SAP Business One Central Management Server (Cloud Control Center) No user concurrency considerations Lightweight in use SLD Agent used to process tasks (e.g. upgrades) this is when the consumption of processing power/ram will increase Consider an average specified server to begin with, monitor and adapt accordingly (especially during maintenance timeframes) 2013 SAP AG.

Introducing the SAP Business One Cloud Sizing Spreadsheet The sizing spreadsheet provides an indication of the size of the landscape you will need to provision based on key input parameters It should not be viewed as a definitive design for your landscape but rather a suggested landscape based on the best information we have today Not all factors have been considered in this spreadsheet, e.g. individual tenant requirements Option for customization of some of the sizing metrics in the Variables tab (hidden by default) 2013 SAP AG.

Starting Point Deployment Key Information All servers in the SAP Business One Cloud Landscape are virtualized The Domain Controller role is isolated on a dedicated server Data files for database, files and backups are located in network storage Benefits TCO - No failover servers reduce the cost of licensing and infrastructure Monitoring - Virtualization provides day to day server monitoring Availability - Domain Controller is isolated to avoid impact of system downtime Failover - Hardware failure can be handled via virtualization technology Flexibility - Provisioning of additional server instances to extend landscape can be achieved easily Potential Issues Dependency Tolerance of failover depends on recovery of snapshot Database Recovery relies on using SQL Server engine Virtualization TCO is increased through the use of virtualization technology Storage No failover storage facilities in case of disaster 2013 SAP AG.

Improved Availability and Scalable Deployment Key Information No local disk but network storage with backup routines for database and virtual machines SQL Server is deployed in a failover cluster New server instances introduced to provide load balancing and stabilization Benefits Stability Presentation Server Farm provides increased stability and loadbalancing for remote access Scalability Increase in SQL Server specification to allow support of more tenants Availability Backup Domain Controller and SQL Server Cluster provide services 24*7 with minimum disruption Storage Isolated storage for data files and virtual machine images Potential Issues TCO Increased cost through the introduction of failover instances Maintenance Backup of virtual machine images and data files have to be done at VM and storage level 2013 SAP AG.

High Availability Deployment Key Information Load balancing on IIS and RDS Gateway servers to achieve high availability of remote access More Presentation Servers in server farm built for load balancing when single point failure. Redundant network devices provide fault-tolerance. Benefits Stability IIS Web Server Farm provides increased stability and loadbalancing for web access Clustering Ensure deployment of virtual machines over multiple physical machines to build on failover clustering at virtualization level Availability Redundancy of servers and devices installed with high availability provides fault tolerance Storage Isolated storage for data files and virtual machine images Potential Issues TCO Much higher cost of infrastructure Management Landscape becomes more complex which increases the amount of data center management 2013 SAP AG.
