Daniel Bryant referred to the work done by David Parnas in the 1970s, and Michael Nygard’s more recent book, Release It!, as good sources for ideas regarding circuit breakers, timeouts, retries, and other fundamental requirements for a resilient system. In many ways, the ideas being implemented are not new-just becoming more important as distributed systems and modular architectures are more common. In 2021, four areas we feel architects are concerned with are designing for resilience, designing for observability, designing for portability, and designing for sustainability.ĭesigning for resilience is vital for modern, distributed systems, where any individual component could fail, and the overall system should remain available. A software architect is responsible for the cross-cutting concerns and making sure that individual components of a large system can work together seamlessly to meet overall objectives. We start by looking at which “-ilities” are most important to architects. The editors were joined by Holly Cummins, an innovation leader on IBM’s corporate strategy team, and a previous speaker at QCon. This year, we’re letting you listen in to the discussion, on an episode of the InfoQ podcast. The next generation of GraphQL features, notably GraphQL Federation and GraphQL Microservices, are showing where to go next after companies have strong adoption of GraphQL.Įach year, the InfoQ editors discuss the current state of software architecture and design, and identify the key trends to watch, resulting in this report and the accompanying graph.In fully-remote work environments, architects are finding new ways to communicate with their teams, and finding replacements for the water cooler chats which were useful for gathering knowledge.As a result, architects are relying on well-established patterns and designs that focus on high cohesion and low coupling, regardless of the underlying technology. The pendulum seems to be coming to rest, after swinging to extremes between monoliths and microservices.Dapr and the Open Application Model are two ways to make building distributed systems easier, and it will be interesting to watch how they are adopted in the future.Innovative architects are designing for resilience, observability, portability, and sustainability. In a cloud-native world, architects are reprioritizing the -ilities they consider most important.
