Microservices do not fail because the idea is wrong. They fail because teams underestimate the bill.
Not the cloud bill. The cognitive bill:
- versioning across boundaries,
- debugging across hops,
- coordination across ownership,
- and the operational work that used to be "someone else’s problem"
If you do not have the maturity to run them, you will build a distributed monolith and call it progress.

Host your own "Cloud"! Why? Because it is amazing in a sense.
Just, for the first time got the directory of a project shared from a foreign nextcloud instance into my own. Works like a charm.
Strangely I seem to be able to re-share this directory. O_o Now I'll have to see if anyone has exploited this already. 😞 Or, more likely, if it has been called a "feature".
But still, I am positively happy about this simple way to cooperatively work over federated instances. Basically, because the Internet has been designed as such a wonderfully distributed place and all these centralized (web-)services have been destroying this through their (economically motivated) monopolization of the "cyber"space.

I've built a new 2-day hands-on training on Event-Driven Architecture - event design, messaging, failure handling, the practical stuff.
Looking for a first company to do a test run. The deal: your team gets the training for free, I get real-world feedback to refine the material.
In-person, on-site, ideally 6-10 people.

Distributed systems are collections of independent computers that coordinate to act as one system. They exist to scale workloads and tolerate failures across networks.
Debugging distributed systems
Almost every system assumes time is correct. Certificates expire, logs align, databases replicate, caches invalidate. Yet time synchronization is treated as background noise.
I would argue that NTP is one of the most critical services on the internet, and almost no one thinks about it unless it breaks. When it does, failures cascade in ways that look unrelated. Authentication fails. Distributed systems disagree. Debugging becomes guesswork.
Time is infrastructure. It just hides better than most.

Traditional #caching fails to stop "thundering herds" where multiple clients trigger the same work during a miss.
This #InfoQ article, Gabor Koos explores a smarter pattern using Cloudflare Durable Objects, treating in-flight work & completed results as two states of a single cache entry.
By routing to a single owner, systems eliminate redundant work and replace complex locking with simple promises.

Infinite scroll works great
until you add search
until you add “previous page”
until users start copying cursors
This article digs into what actually breaks when cursor pagination meets full-text search—and how to fix it properly with Quarkus and PostgreSQL.
No offsets. No magic. Just systems that don’t lie.

Dự án Cuttlefish đạt độ trễ ~40ns cho tính nhất quán nhân quả mà không cần consensus. Nếu các thao tác giao hoán, hệ không cần đồng bộ; không lock, không heap, dùng bloom vector clock 512‑bit, SIMD‑friendly Rust. So sánh: etcd/Cockroach mất 1‑50 ms. #DistributedSystems #Cuttlefish #Rust #CRDT #CausalConsistency #KỹThuật #HệThốngPhânTán
Distributed computing runs programs across multiple networked machines. It matters because it enables scalable, fault tolerant systems that power cloud services, databases, and global applications.
A lot of “scalability work” is really “making side effects predictable.”
Idempotency, retries, timeouts, and clear ownership of state sound boring until your first incident teaches you they were the product all along.
When a system is calm under failure, it is not because it never fails.
It is because 𝗶𝘁 𝗳𝗮𝗶𝗹𝘀 𝗶𝗻 𝘄𝗮𝘆𝘀 𝘆𝗼𝘂 𝗽𝗹𝗮𝗻𝗻𝗲𝗱 𝗳𝗼𝗿.

“Am I online?” looks like a boolean.
In production Java systems, it’s anything but.
DNS failures, captive portals, startup checks that block pods, and HTTP calls that lie politely. This article walks through why connectivity checks break down and how to think about them correctly.

Chi phí của sự chắc chắn: Vì sao "hoàn hảo" là kẻ thù của quy mô trong hệ thống phân tán. Bài viết khám phá "Thuế chắc chắn" – chi phí để giả vờ thế giới không hỗn loạn. Ví dụ từ Pokémon GO: toán học (mất 22 giờ ngủ/năm), sandbox (lịch sử bắt Pokémon có thể sai), và Định luật Little (sự kiên nhẫn là rủi ro trong hệ thống song song). Nếu từng thực thi PACELC, bạn chia sẻ cách bạn cân bằng giữa nhất quán và mở rộng?
