It encourages the use of cloud-native and serverless services in real-world use cases, providing guidance on choosing suitable integration technologies. The article further examines design patterns for achieving success in serverless microservices. It notes that well-established patterns, such as CQRS (Command Query Responsibility Segregation) and Event Sourcing, are crucial for decoupling and scaling systems effectively. Event Sourcing, for instance, stores data as a series of events rather than direct data store updates, allowing microservices to replay events to compute their data stores' state. The post also touches upon how data access patterns can influence polyglot persistence, which involves using multiple data storage technologies within an application based on their suitability for different types of data and access patterns. Practical demonstrations and examples from the AWS console are provided to illustrate these concepts. Finally, the blog post addresses the critical issue of avoiding overload in distributed systems, particularly when a smaller service is subjected to a large influx of requests from a larger client service, such as a data plane overwhelming a control plane. Drawing insights from the Amazon Builder’s Library, the authors discuss the risks associated with disproportionate service scaling and offer mental models and design strategies to prevent system overload. One suggested approach involves the control plane polling an Amazon S3 bucket, where data plane servers periodically write their operational state, to stay updated and prevent overwhelming the smaller service. These strategies are beneficial for teams working on microservices architectures to ensure system stability and performance. #MicroservicesArchitecture #DistributedSystems #AmazonVPCLattice #AsynchronousCommunication #ServerlessMicroservices #EventSourcing #DesignPatterns #AWSCloud #SystemScalability

After operating his architecture practice from a home office for several years, architect Randy Bens sought to expand his workspace in New Westminster, British Columbia. Rather than opting for a traditional commercial rental, Bens decided to utilize his backyard, creating a new office that maintained close proximity to his residence. This innovative solution involved converting a modified shipping container into a self-sufficient architectural studio. The shipping container, a substantial corten steel unit measuring 40 feet in length, 11.5 feet in width, and 9.5 feet in height, was designed and constructed offsite. It arrived at its final location approximately 95% complete, requiring minimal onsite installation. This prefabrication approach streamlined the construction process and allowed for precise control over the design and build quality. The robust construction of the container ensures its durability and also provides the flexibility for relocation, should the firm decide to move in the future. To accommodate the new structure, a smaller foundation was strategically built, allowing the 350-square-foot shipping container to cantilever. This design choice creates the visual impression that the studio is floating, adding an element of architectural interest and lightness to the otherwise heavy structure. The original 1930s house on the property serves as the primary utility hub, supplying the office with essential services including water, sanitary lines, power, and data connectivity. These connections were carefully run underground, maintaining a clean aesthetic and integrating the new studio seamlessly with the existing property. Externally, the shipping container is clad in yellow cedar paneling, a design decision prompted by local city regulations that mandate coverage for shipping containers used as permanent structures. These vertical cedar panels, along with the integrated window and door frames, are expected to naturally weather over time, developing a soft grey patina that will blend harmoniously with the surrounding environment. The steel stairs leading to the entrance have already begun to rust after one winter season, indicating a natural aging process that contributes to the building's character. Inside the studio, the design emphasizes a clean yet warm aesthetic, achieved through the extensive use of birch plywood for interior surfaces. This material choice provides a bright and inviting atmosphere, complementing the natural light entering the space. A prominent feature of the interior is a 19-foot-long desk, meticulously crafted from Douglas Fir. This expansive desk offers ample workspace for employees and provides a focal point for the open studio layout. The overall design aims to create a productive and inspiring environment, facilitating client meetings and collaborative work while maintaining the architect's connection to his home. This project exemplifies a creative and practical approach to expanding a professional practice within a residential setting, utilizing unconventional materials to achieve a functional and aesthetically pleasing result. #ArchitectureStudio #ShippingContainer #HomeOffice #ModularDesign #SustainableArchitecture #NewWestminster #ArchitecturalInnovation #SmallSpaceDesign
