EVOLUTION OF THE "SOFTWARE-DEFINED" CONCEPT

V. B. Egorov

Abstract

The "software-defined" concept was born in relation to networks. Software-defined networking (SDN) assumed centralized automation of network administration and replacement of expensive routers with cheaper switches. The SDN has undergone significant changes when it was extended from university labs to data centers and provider networks. As a result, in practice, SDN networks represent traditional IP networks with full-featured routers, only supplemented with SDN functionality. Following networks, the "software-defined" concept has penetrated the data storage area where the software-defined storage (SDS) has acquired a new important feature - service orientation. With the further extension of the "software-defined" concept to entire software-defined data centers (SDDC) and software-defined clouds, this feature became dominant. It can be expected that the success of SDDCs would make redundant independent SDNs and SDSs. However, the widespread implementation of SDDCs is hindered by difficulties of creating specific orchestration software. Therefore, for an ordinary data center owner, the only opportunity to acquire an SDDC is the purchase of an integrated turnkey solution with ready orchestration software from a reliable supplier.
