Sizing

Sizing means determining the hardware requirements of an application, such as the network bandwidth, physical memory, CPU processing power, and I/O capacity. Hardware and database size is influenced by both business aspects and technological aspects. You must take into account the number of users using the various application components and the data load they put on the server.


Benchmarking

Benchmarks provide basic sizing recommendations by placing a substantial load on a system during the testing of new hardware, system software components, and relational database management systems (RDBMSs). All performance data relevant to the system, user, and business applications are monitored during a benchmark run and can be used to compare platforms.


Initial Sizing

Initial sizing refers to the sizing approach that provides statements about platform-independent requirements of
the hardware resources necessary for representative, standard delivery applications. The initial sizing guidelines
assume optimal system parameter settings, standard business scenarios, and so on.

Expert Sizing

Expert sizing refers to a sizing exercise where customer-specific data is analyzed and used to put more detail on the sizing result. The main objective is to determine the resource consumption of customized content and applications by comprehensive
measurements.

Configuration and System Landscaping

Hardware resource and optimal system configuration greatly depend on the requirements of the customer-specific project. Considerations include the implementation of distribution, security, and high availability solutions by different approaches using various third-party tools. In the case of high availability through redundant resources, for example, final resource requirements must be adjusted accordingly. Some best practices may be valid for a specific combination of operating system and database.

An SUP system which uses MBO based Applications can handle traffic as below.

Category
Request Response Per Hour
Sizing
Memory in GB
Small
30,000
4
Medium
60,000
4
Large
90,000
8

The number of registered users in the system has a relatively minor impact on sizing or performance.

How to create Component-preload.js files for Fiori Applications

-
1           Creating Component-preload.js file 1.1       Use of Component-preload.js: Component-preload.js is a minified , obfuscated and uglified file that gathers all the sources of an application to minimize server requests and drastically reduce the application size. Once the development of an application is finished, the resources should be compressed into that file and deployed on the server.   Creating the file: The steps required to create the file could be found on http://scn.sap.com/community/mobile/blog/2014/12/10/building-fiori-like-app-in-component-preloadjs . Below is a summary of the steps, plus an additional step which I found necessary to make things work. 1-     Download and install Node.js   http://nodejs.org/download/ . Once the installation is complete you can check it by running the following command in the command prompt: npm –v 2-     I...

Building Cost Effective Enterprise Mobile Applications

Mobile apps, designed to run on smartphones like Android or iOS-based phones, are ubiquitous in today’s enterprises. Every enterprise wants to build one or needs one. However, not everyone knows what it costs, or the efforts involved in building it. In this blog, we will attempt to decode the costs & efforts involved in building an enterprise-grade mobile app. These apps are available through the native distribution platforms app stores such as Apple App Store, Google Play Store and other third-party app stores like Amazon Appstore or Samsung's Galaxy Apps. Some enterprises have internal app stores for employees and do not distribute the apps via the native app stores. Based on the number and complexity of desired features, a decent enterprise-grade mobile app’s development and deployment cost anywhere between $25,000 to $500,000. This cost includes the effort of developing a single app for one platform: iOS or Android. The app development cost and effort include the fol...
