DEVNET-1127 Unifying Application Logic with Datacenter Automation
1 like677 views
The document discusses the convergence of application logic and datacenter automation, highlighting the evolution from physical networks to virtualized environments. It explores the concept of microservices and emphasizes the challenges of opaque 'black box' systems that hinder agility and flexibility. The suggested solution is a 'clear box' approach that enables visibility and control over system behaviors to enhance orchestration and service provisioning.

Cisco PublicDevZone 0058 – Unifying Application Logic with Datacenter Automation Conway's Law 7 that this task will fall to others, probably affects some design choices which the individual designer is cailed upon to make. Most design activity requires continually making choices. Many of these choices may be more than design decisions; they may also be personal decisions the designer makes about his own future. As we shall see later, the incentives which exist in a conventional management en- vironment can motivate choices which subvert the intent of the sponsor.! stages of design The initial stages .of a design effort are concerned more with structuring of the design activity than with the system itsel£.2 The full-blown design activity cannot proceed until certain preliminary milestones are passed. These include: 1. Understanding of the boun9aries, both on the design activity and on the system to be designed, placed by the sponsor and by the worltl's realities. 2. Achievement of a preliminary notion of the system's organization so that design task groups can be mean- ingfully assigned. We shall see in detail later that the very act of organiz- 1 A related, but much more comprehensive discussion of the behavior of system-designing organizations is found in John Kenneth Galbraith's, The New Industrial State (Boston, Houghton Mifflin, 1967). See especially Chapter VI, "The Technostructur<!." 2 For o discussion of the problems which may arise when the design activity takes the form of o project in a functional environment, see C. J. Middleton, "How to Set Up o Project Organization," Harvard Business Review, March-April, 1967, p. 73. 28 4. Coordination among delegated tasks. 5. Consolidation of subdesigns into a single design. It is possible that a given design activity will not pro- ceed straight through this list. It might conceivably reorga- nize upon discovery of a new, and obviously superior, design concept; but such an appearance of uncertainty is unflattering, and the very act of voluntarily abandoning a creation is painful and expensive. Of course, from the Dr. Conway is manager, pe- ripheral systems research, at Sperry Rand's Univac Div., where he is working on recog- nition of continuous speech. He has previously been a research associate at Case Western Re- serve Univ., and a software consultant. .He has an MS in physics from CaiTech and a PhD in math from Case. :C»ATAMATION "Any organization that designs a system will produce a design whose structure is a copy of the organization's communication structure".
