Upgrading Aurora PostgreSQL: Blue/Green deployment journey

When it comes to major database version upgrades, downtime is the enemy. Recently, we successfully upgraded our Aurora PostgreSQL cluster from version 13 to version 17 using AWS’s blue/green deployment strategy, achieving an impressive 3 seconds of write downtime.

Designing on-demand ML training infrastructure on AWS: A practical architecture guide

Machine learning projects do not depend only on good models. They also depend on the infrastructure behind them. Training workloads are expensive, unpredictable, and often inefficient when run on static environments. As organizations scale their AI efforts, the ability to provision training infrastructure on demand becomes critical for both cost control and speed of experimentation

The importance of understanding basic front-end development principles for UX/UI designers

Integrating a foundational knowledge of front-end development can elevate your work to new heights.

The evolution of iOS state management

Every iOS developer has lived this moment: you're debugging a screen where a label shows stale data, a button is inexplicably disabled, and somewhere in a 1,500-line view controller, a boolean flag named `isLoading` mocks your attempts to understand what went wrong. State management, the art of keeping your UI in sync with your data, has been the recurring challenge of iOS development since the App Store opened in 2008. Each generation of developers has faced it, solved it differently, and passed new problems to the next.

Swift 6 concurrency: the fundamentals (1/3)

Imagine you're running a restaurant kitchen. You could cook each dish one at a time - chop vegetables for dish A, cook dish A, plate dish A, then start on dish B. This **serial** approach is simple and safe, but customers would wait forever. Or, you could run the kitchen like a real restaurant: multiple chefs working simultaneously - one chopping vegetables, another grilling, another plating. This **parallel** approach serves customers faster, but introduces complexity. What if two chefs reach for the same knife? What if the plating chef starts before the grilling chef finishes?

Swift 6 concurrency: advanced patterns (2/3)

In Part 1, we covered the building blocks of Swift 6 concurrency - async/await, actors, Sendable, and MainActor. Now it's time to put those fundamentals to work. In this second installment, we'll explore the patterns you'll reach for daily: streaming data with AsyncSequence, fine-tuning task priorities, integrating concurrency safely into SwiftUI, and migrating away from Combine. We'll also walk through the most common pitfalls so you can sidestep them before they hit production.

Optimizing mobile app performance with AWS CloudFront and AWS Global Accelerator

Today, we are leveraging various cloud solutions to connect and deliver core functionalities of our apps.

Migrating to Swift 6: a practical guide (3/3)

You've learned the concurrency patterns - now it's time to bring them into your production codebase. This final installment covers the strategic side of Swift 6 adoption: how to assess your codebase, choose the right migration strategy, enable strict concurrency incrementally, and avoid the pitfalls that derail real-world migrations.

Choosing the right IoT platform strategy: build, buy & integrate, or buy off-the-shelf

As businesses increasingly adopt IoT solutions, they face a crucial decision: Should they build their platform from scratch, buy and integrate existing solutions, or purchase an off-the-shelf platform? Each approach has distinct advantages and trade-offs, particularly in cost, flexibility, and time to market. In this blog post, we compare all three approaches, outlining their pros and cons. Finally, we dive deeper into the Buy & Integrate approach using AWS IoT Core and related AWS IoT services.
