Mainframe computing and the trendy agile improvement methodology known as DevOps don’t must be mutually unique. The Virginia Division of Motor Autos is displaying why.
The company, which providers 6.2 million licensed drivers and identification card holders and processed 16.8 million transactions final 12 months, has efficiently adopted DevOps and its steady integration and improvement processes with out abandoning the database administration system and high-level programming language that has served it for 30 years.
“Agile provides us a a lot, a lot clearer view of what merchandise we need to construct,” Joshua Elkins (pictured), a Virginia DMV software program developer, mentioned throughout a presentation earlier this week on the Software program AG Worldwide Consumer Teams convention in Dublin, Eire.
Maintaining with the occasions
A lot of the division’s purposes are primarily based on Adabas, an inverted record database from 1971, and about 80% had been written within the companion Pure programming language, which was launched in 1979. Though cloud-native improvement is usually related to extra up to date info expertise infrastructure, Software program AG has continued modernizing Adabas and Pure to maintain them according to cloud-native constructs. The corporate has mentioned it would help each not less than by means of 2050.
The newest language model, NaturalOne, integrates with the favored Eclipse improvement atmosphere and might expose and use purposes through utility programming interfaces. That allows the DMV to tie into back-end providers reminiscent of verifying passports, capturing pictures of driver’s licenses, sharing information with the Nationwide Legal Data Middle, and permitting drivers to handle their EZ-Move accounts. It’s adopting automated testing and mobile-first improvement.
Elkins mentioned the steadiness of the mainframe again finish has accelerated the shift to DevOps. “We’ve been capable of accomplish fairly a bit in a brief interval,” he mentioned. “It’s quite a bit simpler as a result of we have now a dependable mainframe on the again finish. It’s not typically we have now to inform clients we will’t assist them.”
Virginia DMV’s expertise challenges generally held beliefs that legacy platforms can’t evolve with the occasions. Software program AG has migrated Adabas and Pure to Linux for each on-premises and cloud deployment. Each can run inside software program containers, connect with NoSQL and information lake storage and deal with streaming information.
“The workforce has advanced Adabas and Pure for the long run,” mentioned Stefan Sigg, Software program AG’s chief product officer. “You’ll be able to keep in your mainframe, migrate to Linux or combine along with your cloud technique.”
Tradition problem
Elkins mentioned expertise has been much less of a problem to reaching the DMV’s agile improvement targets than tradition. When he joined the event group, he mentioned, “I used to be 23, and nobody else on the workforce was underneath age 60. It was a shock to log right into a green-screen terminal.”
On the time, utility improvement adhered to the “waterfall” methodology, wherein necessities had been outlined upfront, and builders and enterprise customers not often interacted. In these early days, code typically wasn’t delivered for months, and there was little latitude for change as soon as specs had been finalized, Elkins mentioned.
“Previous to transferring to agile, we struggled with prioritization,” he mentioned. “Agile provides us a a lot, a lot clearer view. It permits for extra adaptive planning and has taught us the right way to negotiate” with the enterprise aspect.
However shifting to agile “isn’t as simple as you’ll assume,” he famous. “It takes iterative workflows and multidisciplinary groups. It isn’t an A-to-Z path. It’s a must to eradicate siloes and egos.”
Pace dividend
The payoff has include a quicker and extra nimble supply schedule that has reduce wait occasions in DMV places of work, elevated motorists’ use of self-service web site options, and boosted scores on each buyer and worker satisfaction surveys.
The event workers has benefited from broader abilities and deeper involvement with the enterprise. “Many individuals are on the trail to changing into full-stack builders, whereas earlier than, they might have been app builders alone,” Elkins mentioned.
The initiative has even helped entice latest College of Virginia graduates who would possibly by no means think about working in a mainframe store. “Agile has been incredible as a result of it’s a chance for the true specialists to take a seat with these new folks,” Elkins mentioned. “It’s collaborative and steady.”
Don’t be too fast to tug again the covers on the mainframe, he suggested. Referring to the cryptic Job Management Language that manages processing on huge iron, he mentioned, “You’ll be able to think about their response after they had to have a look at JCL.”
