Article ITNEXT · 2y Why is gRPC so much faster than a JSON-based REST API? gRPC is faster than a JSON-based REST API primarily due to its use of HTTP/2 and Protobuf. HTTP/2 reduces request wait times through asynchronous requests and connection reuse. Protobuf, being binary-based, is more compact and faster during serialization/deserialization compared to JSON. While gRPC offers significant performance benefits, it also introduces complexities in load distribution, troubleshooting, and managing contracts. It's recommended for scenarios needing high performance and capable of handling its complexities, though REST + JSON remains a viable option. 119 1 2. 2 [](https://daily.dev/posts/a-few-unshakable-principles-for-writing-better-code-pcgxjox0w "A Few Unshakable Principles for Writing Better Code") Article ITNEXT · 2y A Few Unshakable Principles for Writing Better Code Explore essential principles for writing better, cleaner code.

Each pattern relaxes or enforces certain constraints such as type, identity, and temporal order of data packets, allowing for flexible data processing and transformation in various use cases. Pipes and Filters involve strict stepwise processing, while EDA and CQRS introduce complexity and flexibility by aggregating and storing events. MVC entirely abandons type and identity constraints in favor of broader functionality. 72 1 5. 5 [](https://daily.dev/posts/middleware-ymvwpwo9e "Middleware") Article ITNEXT · 2y Middleware Middleware acts as a low-level layer providing connectivity and communication for a system of services, improving scalability and error recovery.

Basic metapatterns like Monolith, Shards, Layers, and Services provide foundational structures, while extension and specialized patterns such as Middleware, Shared Repository, Proxy, and others offer more intricate designs to address specific needs. Understanding these parallels can enhance creativity and flexibility in software design. 42 8. 8 [](https://daily.dev/posts/hexagonal-architecture-ao5at2inp "Hexagonal Architecture") Article ITNEXT · 2y Hexagonal Architecture Hexagonal Architecture isolates business logic from external dependencies using two-way adapters, protecting from vendor lock-in and allowing late changes of third-party components. It supports cross-platform development and eases testing but may hinder performance optimizations and requires careful preliminary API design. 33 9. 9 [](https://daily.dev/posts/fuzz-testing-go-http-services-utrurxxqh "Fuzz Testing Go HTTP Services") Article ITNEXT · 2y Fuzz Testing Go HTTP Services Fuzz testing, or fuzzing, is an automated software testing technique used to find bugs, crashes, and security vulnerabilities by inputting large amounts of random data into a program. It is now integrated into Go’s standard library as of Go 1.18, making it part of the regular testing package. Fuzz testing can reveal bugs that traditional testing might miss and is a recommended practice for improving the robustness of code, including HTTP services. The post provides step-by-step instructions for creating fuzz tests in Go, including an example for fuzzing HTTP handlers using Go's \`httptest\` package. 30 1 10. 10 [](https://daily.dev/posts/mesh-y45cyxivq "Mesh") Article ITNEXT · 2y Mesh Mesh is an architectural pattern that uses interconnected, layered shards as middleware, enhancing scalability and fault tolerance in distributed environments. It supports dynamic scaling and high availability but may introduce communication artifacts and performance overhead. Meshes vary significantly by structure, connectivity, and layers, and are implemented in various forms such as Peer-to-Peer Networks, Leaf-Spine Architecture, Actors, and Service Meshes. 22 11. 11 [](https://daily.dev/posts/how-the-cka-certification-has-changed-from-2021-to-2024-pbqw3pifj "How the CKA Certification Has Changed from 2021 to 2024") Article ITNEXT · 2y How the CKA Certification Has Changed from 2021 to 2024 The CKA certification has undergone some changes from 2021 to 2024\. The cost increased from $299 to $399, and the certification validity period was shortened from three years to two.
