Learnings from Spotify Cellular Engineering’s Latest System Migration

Not too long ago, the Spotify Mobile Engineering Group elaborated on their practical experience with a recent system migration. Doing work on an initiative beneath the Cellular Engineering Method software, the crew migrated their Android and iOS codebases to create with Bazel, Google’s open up-supply establish technique.

Mariana Ardoino and Raul Herbster from the Spotify Cell Engineering staff pondered on the learnings from migration in a blog put up. The migration energy impacted extra than 100 squads across Spotify. Acknowledging that migrations of different dimensions and complexity will be “the norm” in the long run, the crew set the context by highlighting the have to have to define the scope of migration.

Frequently when the extent of migration is unknown, it can make feeling to concentration on values and realize the ambitions of the migration. The staff recommends starting up modest with proof of concepts (POCs) and validating it with stakeholders as an alternative of pinpointing all probable scenarios at the start. It is also practical to understand the wants of stakeholders with this migration by collaborating with them in these early phases.

When there is a substantial range of squads impacted, and the development is sluggish, comprehensive infrastructure and architecture changes may well seem not possible. This sort of scenarios connect with for a greater stage of stakeholder engagement. Staying in speak to with stakeholders by means of Slack/e-mail groups, and sharing the progress through publication and place of work posts may perhaps re-emphasize the importance of migration. On the lookout for automation opportunities may well support for the duration of the migrations. Reserving time for analysis spikes is also a very good option to consider, which can consist of swarming with groups to work on the migration.

As a facet, emphasizing the facet of collaboration in the context of Agile / DevOps transformations, Nigel Kersten, CTO at Puppet claimed,


Basically the difficulty is that all of these transformations have a large people today-interaction element, and the even larger and older you are as an corporation, the far more challenging it is to improve how men and women interact, and the increased up the chain you have to go to produce organizational adjust.


The Spotify Mobile Engineering group outlined that competing priorities are a “simple fact of daily life” for any platform crew associated in migrations. Whether or not a migration includes adopting new technological innovation or cutting down the tech financial debt, the inspiration stage of the team may get afflicted thanks to gradual development on migration. The crew endorses analyzing the development of migration continuously, motivating the staff by displaying the favourable effects of migration, and tweaking the methods to realize specific aims of migration.

Lastly, talking about the aspect of accountability, the Spotify Cell Engineering group advises not to hope inside/external alignment on driving improve more than the study course of time. Using dashboards, retaining a migration timeline, and using details or trend graphs may well support visualize the progress and highlight required changes.
