Walmart OneOps Won’t Be One-Upped

By: David Geer on May 4, 2016 Leave a Comment

One of the biggest names in retail also is kind of a big deal in DevOps. Walmart has developed its own platform, OneOps, designed to streamline operations and keep its application development schedule in check.

“OneOps is an open source cloud and application lifecycle management technology platform with benefits including cloud portability so developers can seamlessly move applications, databases or entire cloud environments from one cloud provider to another,” says Brian Johnson, VP of Engineering, Platform, Walmart Labs. The latter feature allows developers to leverage the broad selection of cloud environments and pricing schemes to their advantage.

The OneOps platform deploys Walmart website adds/changes, launches new mobile features such as Walmart Pay, and creates APIs so third parties such as Hiku can tap into Walmart’s online grocery offerings, at speed and with a lower investment in the cloud, says Johnson. The OneOps platform once only managed the Walmart.com e-commerce site, but now it also serves individual Walmart stores and supports other initiatives.

According to Johnson, OneOps undergirds and empowers the work of developers as follows:

  • OneOps continuous lifecycle management continuously auto-pilots the process of automating application scaling and repair whenever any unforeseen changes take place.
  • OneOps promotes accelerated innovation so software engineers can spin up new environments for app hosting in minutes, since the DevOps platform skirts the need to specify the intricate details of any one cloud environment by modeling that for the developer.
  • This abstraction of the cloud environment gives developers control over the tools and technologies they select regardless of the cloud provider they use.

Life Before OneOps

“Before OneOps, the process of updating Walmart’s website was so tedious that we rolled out updates only every two months. The process used hundreds of manual steps and required significant resources,” Johnson says. “This was time-consuming and created room for manual errors.”

Before OneOps, A/B testing was expensive and time-consuming, taking months to set up multiple cloud environments and conduct tests. By the time testing was done, the rationale for the new feature had waned and whatever opportunity it was created to take advantage of had passed, he says.

At that time, creating enough virtual machines (VMs) in time to handle peak shopping events and traffic would have taken teams of people months to complete, at the risk of exorbitant operating costs, Johnson adds.

The OneOps Afterlife

OneOps now fully manages the Walmart e-commerce platform such that in a typical day the site sees more than 1,000 new software deployments, which developers execute on demand in a span of minutes on average, says Johnson.

OneOps serves a variety of customers such as consumers of Walmart.com, who on black Friday found their shopping experience supported by the tens of thousands of VMs OneOps was able to spin up across multiple clouds to cradle the peak traffic, Johnson says. OneOps is the DevOps and cloud platform for SamsClub.com as well.

Solving the Single Cloud Provider Dilemma

Walmart targeted OneOps to use multiple cloud providers easily, because of the pitfalls of being locked in to a single provider. “The fear of vendor lock-in is the major challenge to cloud service adoption. Cloud vendors like AWS don’t make it easy for customers to move from one cloud to another. The complexities of cloud service migration mean that many customers stay with a provider that doesn’t meet their needs simply to avoid the cumbersome and expensive process of migration,” says Johnson.

Further vendor lock-in concerns, he notes, include:

  • Contracts of lengthy duration geared toward ensuring higher server utilization, maximum ROI and profitability for the cloud provider but providing little benefit for the cloud customer.
  • Lack of freedom of choice where storage space, processing power, bandwidth and tools and technologies are concerned.
  • Because it is typically difficult to find any two cloud providers that use the same tools, compatibility is an issue. “You can’t simply port your site to a new provider without rebuilding it using the new provider’s toolsets,” says Johnson.
  • “While you build and test your site on the new cloud platform, you are still paying to maintain it on the old provider, doubling your costs,” says Johnson.

This is why OneOps abstracts the use of differing cloud providers, making porting easy.

The Big Question Is …

OneOps solves a unique set of DevOps challenges related to the cloud. Can you name another platform that does something similar?
