DDS Delivers Cost Savings and Performance in Mission‑Critical Systems

\n

We frequently highlight the technical strengths of the Data Distribution Service (DDS) standard, but the financial upside is equally compelling. In a landscape of tightening budgets—whether from sequestration or other cost‑cutting pressures—organizations can now adopt a middleware that delivers both higher performance and lower total cost of ownership.

\n

Take the Army’s Joint Battle Command‑Platform (JBC‑P) as a case study. The program set out to track 100,000 positions per second, but after eight years of development and 500 000 source lines of code (SLOC), the deployed system required 21 servers, delivered only 20 000 tracks at peak load, and suffered frequent reliability issues.

\n

When we break down the economics, the numbers become stark. Using a conservative $20 per line estimate, 500 000 SLOC translates to $10 million in development spend. If we look at developer costs—20 engineers at $120 000 per year over eight years—the total reaches $19.2 million. Hardware and software for 26 servers add another $260 000, and ongoing support—30 engineers at $120 000 per year—cost $3.6 million annually.

\n

In total, the legacy solution cost between $10–19 million to build and $3.6 million per year to support, yet it fell short of its performance targets.

\n

Enter DDS. After a rigorous evaluation of scalability, reliability, and cost, the Army selected DDS as the middleware of choice. RTI helped deliver a prototype in under a week, and the resulting DDS‑based system exceeded expectations—processing 250 000 tracks with full redundancy and proving ready to handle 500 000 tracks, five times the original specification.

The savings are substantial, broken down by category:

		Legacy		DDS
	Price	Requirement	Cost	Requirement	DDS	Savings
SLOC	$20/line	500 K lines	$10,000,000	88 K lines	$1,760,000	82 %
Developers	$120,000/year	20 staff	$2,400,000/year	10	$1,200,000	50 %
Hardware	$10,000/server	26 servers	$260,000	2	$20,000	94 %
Support	$120,000/year	30 staff	$3,600,000/year	6	$720,000/year	80 %

These figures are per Network Operations Center (NOC). The Army operates five NOCs—three production and two dedicated to development, training, and backup—so the aggregate savings are even larger.

\n

Beyond sequestration pressures, DDS offers a strategic advantage for any organization seeking a more efficient, cost‑effective solution. For roughly 25 % of your current annual maintenance budget, you can implement a DDS‑based platform that delivers a return on investment within the first year.
