The terms steady integration and steady shipping and delivery are frequently utilized together and blended into 1 instrument set, but 1 enterprise learned that they have an affect on unique areas of IT as groups undertake new procedures.
Option Hotels started its DevOps transition additional than four a long time back and proven steady integration tests of software code by way of the open source Jenkins instrument early on. Nevertheless, it relied on homegrown scripts to make its steady shipping and delivery pipeline right up until final 12 months, when it sought a additional systematic method.
Previous spring, the hotel chain reviewed CI/CD tools such as XebiaLabs and the AWS CI/CD suite, which involves CodePipeline and CodeDeploy utilities. It also seemed at Netflix’s Spinnaker and tools from Harness.io, which emphasis on steady shipping and delivery pipelines. Finally, it chose to adhere with its present CI procedures, and insert steady shipping and delivery from Harness, a seller that emerged from stealth in late 2017 with the concept that CI and CD are essentially unique disciplines.
“Harness appealed to us because it’s offered via SaaS, so we will not have to babysit the instrument and do its care and feeding,” Judson explained. “But it’s also centered on the deployment piece, which meant we could retain the Jenkins build careers we by now experienced in position.”
Option Hotels was satisfied with the CI system and tests matrix it experienced set up, which integrated tools from SonarQube and Checkmarx with Jenkins. Continuous shipping and delivery pipelines, on the other hand, are additional centered on automating the infrastructure that supports software deployments. This consists of other styles of ability sets, and the everyday work of unique IT personnel — namely, IT ops.
“We’ve found the largest advancement in steady shipping and delivery in data facilities, the place we utilized scripts on load balancers to segment targeted visitors for canary deployments,” Judson explained. “We’re capable to deploy a lot a lot quicker there and we’re a lot additional confident in our deployments.”
Option Hotels is nevertheless rolling out the Harness instrument throughout additional than one,200 unique programs it maintains in the AWS cloud and its data facilities in Phoenix. But for programs the place the instrument is in use, the firm was capable to deploy software updates 20% additional frequently final 12 months, and so much, this 12 months, that raise has been additional than thirty%.
Continuous shipping and delivery pipeline clarifies DevOps roles
Though the addition of a CD instrument has smoothed the workflow that connects software builders and IT ops pros, it has diminished the amount of interaction in between them — in a great way.
For instance, the hotel chain’s IT ops crew can use Harness to automate the patching of its Java applications. In the previous, this necessary handbook labor by both of those builders and ops pros, but with security patching now finished on the fly, that system would not need builders to devote time on it.

“The developer and ops facet have truly come to be additional centered on their different roles, and ops has a dashboard to see what’s coming and how deployments are likely for on their own,” Judson explained.
Every single so frequently, the Option Hotels IT ops crew will have to roll back deployments to solve difficulties, which the Harness instrument also automates. Nevertheless, the crew is nevertheless doing work out the connections in between Harness and its Kafka data pipelines and Terraform infrastructure as code tools to assure that it would not stand up redundant infrastructure to assist new deployments, and that if it does, they can be rolled back smoothly.
Harness involves cloud expense analysis tools with its product or service that monitor the efficiency of software deployments, but these measurements are retrospective. Judson explained he’d like to see Harness offer predictive expense analysis as nicely, based on the historic data.
A Harness spokesperson declined to share unique roadmap details but explained such a characteristic is staying regarded as by the firm.
