There is no “Agile” outcome if the network “isn’t”.

I must start this blog with an apology (sorry) – the grammatical form of the title would have me struck down by my primary school English teacher, however I can find no other way to convey my meaning. “Agile” is the current next big thing and rightly so for many organisations whether development, operations or both. If speed of development (application), accelerated time to market and potentially reduced development costs are the primary aims of the enterprise, “Agile” delivers immense value.

But the euphoria seems to drive a mushroom cloud of activity involving selected internal operational and technology areas, for example servers, storage and compute. It’s clear “Agile” discussions ignite wholesale changes in those common areas, but has been slow to affect others most notably networking & security – and there lies a problem. At present application development teams, IT operations functions and most importantly the line of business teams are proactively gravitating towards each other as the “Agile” train pulls into the station. The cultural, emotional and operational shift required to make “Agile” a reality is now very real with green shoots of benefit now starting to appear.

But I challenge the effectiveness of the current “Agile” momentum due to a major elephant remaining in the room – network readiness. At present I view first hand many organisations with “Agile” transformation a fundamental element of their corporate manifesto but continuing with a network that may be highly reliable and functional but one not lubricating or accelerating the agile journey. Does this instantly fast forward to a software defined networking discussion – my heart says no but finally my head overrules with yes. Software defined networking is NOT networking without hardware – unless everything we know is physics is to be rewritten or eliminated that will never happen. But it is networking optimised by the use of software to increase programmability (and therefore personalisation) and automation (and therefore consistency and efficiency).

The benefit software defined ideals deliver to networking outcomes are many fold but must notably security benefits, speed and consistency of change which in turn makes the network agile. Surely this must signpost a notable change of priority, to shift network transformation further up the business technology priority list to enable tangible business value – if your network is not agile “is the business truly delivering agile operational or workload outcomes”.

Agile development is here to stay and with businesses now operating at warp speed agile is helping to drive organisations into the brave new ever changing world. But a network however stable, ridden with complexity and human latency MUST now change to be the optimum transport of digital change. It’s time to ask your organisation if the network is really making the business agile – if not, now is the time for change.
