In the dynamic realm of software development, successful industry leaders share a common proficiency in four pivotal metrics: Deployment Frequency, Lead Time for Changes, Time to Restore Service, and Change Failure Rate. Yet, achieving high performance in these areas within the mobile world presents unique challenges. This talk delves into the depth of best practices and innovative technologies within React Native and mobile DevOps ecosystems, all aimed at our ultimate goal: the continuous delivery of value to our users.
Mastering Mobile DevOps: Leveraging React Native for High Performance
AI Generated Video Summary
Today's Talk explores mobile DevOps and how React Native simplifies mobile releases. Key metrics for DevOps performance include deployment frequency, lead time for changes, time to restore service, and change failure rate. React Native allows over-the-air updates, eliminating the need for resubmission. Overdue updates offer advantages like bypassing app store validations and quick updates, but have limitations. Other options to consider are in-app models for forced upgrades, EAS Build and Submit, Repack for micro-frontends, and upcoming server components in React Native.
1. Introduction to Mobile DevOps
Today, we'll dive into mobile DevOps and see how React Native can simplify mobile releases. Let's clarify what DevOps means. It's the art of producing top-tier software seamlessly and effectively. We'll focus on continuous delivery and its unique aspects in mobile development. Let's delve into four key metrics: deployment frequency, lead time for changes, time to restore service, and change failure rate. These metrics highlight our DevOps performance. The elite performers can make deployments on demand and changes in production under a day. Now, let's explore the unique realm of mobile challenges, starting with device fragmentation.
First, let's clarify what DevOps really means. Its definition remains consistent, whether for mobile or other platforms. I define DevOps around four key pillars, continuous integration, continuous delivery, continuous feedback, and lastly, collaboration. In any DevOps journey, unity is key. It is art of producing top-tier software seamlessly and effectively.
Today, we'll focus on continuous delivery and its unique aspects in the context of mobile development, as this is where it diverges significantly from web development. But first, remember that we can only enhance what we can measure. In DevOps, this is the cornerstone for making the right choices.
Let's delve into four key metrics that can help us identify release processes, trends, and areas for growth. The first one is deployment frequency. It's a measure of your team's agility and ability to deliver new features, updates, or fixes. Next, we have lead time for changes. It measures the speed from code commit to code deployment. The third one is time to restore service. This metric is crucial for assessing your team's responsiveness and capability in handling incidents. The shorter time to restore service is indicative of robust incident management and quick problem solving abilities. Lastly, we have the change failure rate. A lower rate indicates robust testing and quality checks. Together, these four key metrics paint a clear picture of our DevOps performance, highlighting both our strengths and areas to enhance.
The 2023 state of DevOps report compares thousands of companies across these four key metrics. The elite performers can make deployments on demand and changes in production under a day. They have just a 5% failure rate and can recover within an hour. And 18% of participants achieved this. While these stats are eye-catching, the true worth is in the journey, the learnings and the constant refining of your DevOps practices.
Now that we set up our goal, let's delve into the unique realm of mobile challenges. The first one is device fragmentation.
2. React Native and Over-the-Air Updates
Think about it, we have so many device models out there and making sure our apps works well on all of them is tough. The second one is app upgrades. Think about releasing an app version and discovering crashes for all your users and like websites you can't easily roll back and you can't force users to update their apps. Your only path is to fix the issue, roll forward and hope your users upgrade.
Finally, store reviews is another pivotal aspect of mobile development. Most of the time, they take between 24 to 48 hours, but they can last until one week. Once we submit, we are on the store's clock. And remember, given the elite standards, mobile development is challenging. Hitting these benchmarks feels like impossible.
3. Advantages and Impact of Overdue Updates
We're nearing the conclusion. If you're hungry for more, you can consider checking out for example in-app models for forced upgrades. They are invaluable, especially when addressing critical security issues. You can also check EAS Build and Submit. It's user-friendly, making app releases a breeze even if you're not a seasoned mobile developer. For a fresh perspective on micro-frontends in React Native, you can explore Repack and its integration with Webpack and Module Federation. And finally, keep an eye out for server components, as they are coming in React Native too.
