I moved from LastPass to 1Password. I'm not happier
I've been a long-time LastPass client. I recently switched to 1Password in an attempt to overcome a few LastPass cons. I solved them, but I'm not sure the situation improved.
Distributed systems evolution: topology changes
Evolving distributed systems architecture is challenging. It's not only a matter of evolving message contracts or processes state. Surprisingly, deployments can play a role in creating more challenges.
Distributed systems evolution: processes state
Evolving distributed systems architecture is challenging. Addressing message evolution is one aspect. Another one is evolving existing processes and their persisted status.
Distributed systems evolution: message contracts
Evolving distributed systems architecture is challenging. If the system is message-based, the first challenge comes from evolving message contracts.
Distributed systems evolution challenges
What are the challenges posed by evolving distributed systems architecture? In this short series of articles, we'll understand the critical factors we should be keeping an eye on and how to address them.
Know your limits. Infinite scalability doesn't exist
There is this myth that we can design today for tomorrow's unknown requirements. Somehow we believe that we can put in place a robust architecture that will scale forever, no matter what. I'm sorry, that's impossible.
Do we need to debug distributed systems?
We're humans. We are designed to apply previous experience and knowledge to new problems. When faced with distributed systems, we want to debug them. Do we need that? And, can we debug distributed systems?
