DEVTOME.COM HOSTING COSTS HAVE BEGUN TO EXCEED 115$ MONTHLY. THE ADMINISTRATION IS NO LONGER ABLE TO HANDLE THE COST WITHOUT ASSISTANCE DUE TO THE RISING COST. THIS HAS BEEN OCCURRING FOR ALMOST A YEAR, BUT WE HAVE BEEN HANDLING IT FROM OUR OWN POCKETS. HOWEVER, WITH LITERALLY NO DONATIONS FOR THE PAST 2+ YEARS IT HAS DEPLETED THE BUDGET IN SHORT ORDER WITH THE INCREASE IN ACTIVITY ON THE SITE IN THE PAST 6 MONTHS. OUR CPU USAGE HAS BECOME TOO HIGH TO REMAIN ON A REASONABLE COSTING PLAN THAT WE COULD MAINTAIN. IF YOU WOULD LIKE TO SUPPORT THE DEVTOME PROJECT AND KEEP THE SITE UP/ALIVE PLEASE DONATE (EVEN IF ITS A SATOSHI) TO OUR DEVCOIN 1M4PCuMXvpWX6LHPkBEf3LJ2z1boZv4EQa OR OUR BTC WALLET 16eqEcqfw4zHUh2znvMcmRzGVwCn7CJLxR TO ALLOW US TO AFFORD THE HOSTING.

SAP and the change of paradigms

Since its first version of their enterprise software in 1973, SAP has gone through a lot of technological changes. 1973 marks the first milestone with the release of SAP R/1. R stands for “real time data processing”. In 1979 R/2 was released which included major changes in the foundation of the software. R/2 especially changed the way that the data was processed by introducing abstraction of the database as well as the use of a global data dictionary. These fundamental developments ensured the success of SAPs data model over the years and are still visible in todays SAP releases.

SAP R/3 which came out in 1992 marked the biggest milestone so far for SAP. For the first time a client/server architecture was introduced, leaving the mainframe area behind. At the time it was ground breaking to be able to work with SAP on a thin client machine rather than on a large mainframe server.

In the second half of the 90s SAP began to roll out more and more additions to its ERP core system. Two of the biggest products released during this time were the SAP CRM (Customer relationship Management) and SAP BW (business warehouse) systems. The end of the 90s also introduced the topic of service oriented architecture (SOA) to the SAP portfolio. Using SAPs new technology stack SAP Netweaver, which at the time consisted of two different application servers - the so called dual stack (ABAP and Java), SAP launched a fully featured SOA platform and began to roll out business functionality in form of so called enterprise services.

In 2012 SAP announced a major overhaul of the technological basis of their systems. With mobile phones and tablets being strong on the market, offering new UI opportunities and the rising challenge of integrating big data, available to SAP customers through technological advances in areas of manufacturing, sensor data or social media, it was clear that SAP had to rethink their software. The old UI which had not really changed since the R/3 release was not modern enough and the databases and table structures which SAP relied on since R/2 had come to a technological boundary when facing big data challenges. The approach that SAP has taken to overcome these shortcomings can be seen as one of their most radical changes so far, only comparable to the switch from the mainframe to R/3. Not only did they change their whole front end approach by offering an up to date HTML5 framework called SAP UI5 which has started to replace the classic SAP GUI in several areas already, but also the foundation of SAPs success has gone through fundamental changes. The database layer was completely redesigned by using an own developed in-memory database called SAP HANA. With SAP HANA it is now possible to process large amounts of data on the fly, removing the necessity to duplicate data for asynchronous processing within a data warehouse application like SAP BW.

It remains to be seen how SAP customers can cope with all the changes which are being delivered with the latest revisions of SAPs software. Concerning the required infrastructure and hardware for these new products, SAP already began to put a lot more focus in the area of hosted appliances which are known as cloud computing today.
