SAP Basis range of services
The so-called SAP message server also belongs to the application layer. Only one instance of this server exists in the system. It mediates between the services and applications. In concrete terms, this means that the message server takes care of load balancing and determines, for example, on which application server a user logs on. Communication between application servers is also the domain of this message server.
Hosting environments and third-party offerings have also contributed to these improvements. Public cloud environments such as Azure and AWS provide a layer of abstraction that eliminates the difficult task of maintaining the hardware that was required with SAP on-premises.

In order to make a transaction in cryptocurrencies, you do not have to let your bank know about it as you would for "normal" money, but you have to use the Private Key to prove that you own the coins. The transaction looks like a piece of the puzzle. Half of the puzzle piece consists of information about the coin set, time and public address of the sender or receiver. The other half is the signature of the private key belonging to the sent public address. Both halves make this piece unique. Changing only one piece of information would completely change the whole transaction or the appearance of the puzzle piece. This transaction is transferred to the network or to the miner and is checked for correctness first. If everything fits, the transaction will be sent to other miners who will do the same. Otherwise, the transaction is ignored. Miners try to integrate the transactions into a block. This is called mining and we have described it so that the miners put the puzzle pieces together into a puzzle (block). A small part of a block to be integrated follows from the block that was previously mined. If all miners accept the correctness of a completed block, they will all work the next one immediately. The puzzle (block) is fixed and is irrevocably connected to the block before or after. The blocks form a chain and are called blockchain, which contains all the transactions that have ever been made and is visible and unchangeable by everyone. In doing so, blockchain replaces a central institution and avoids double-spending, which ultimately gives value to a cryptocurrency. Smart Contracts The biggest advance compared to Bitcoin and similar applications is that second-generation blockchains, such as Ethereum, use the so-called Turing-Complete script language Solidity. This enables calculations to be made within the blockchain. While Bitcoin allows only rudimentary multi-signature functions, Ethereum opens the door to much more complex operations called smart contracts. Smart contracts are contracts in which a decentralised blockchain ensures their unchangeability and execution.
In order to cope with the digital transformation in general, but also to cope with the changing demands on the SAP basis and its scope of responsibility, it is necessary to revise existing roles and define and establish new roles. These include the roles of the technology architect, new features of the Subject Matter Expert (SME), and the role of the Expert Team Lead in leading a group of experts. Further information can be found in chapter 7.1 and 9.3 of the Master's thesis.
