Too much magic?

A good thinking about the "magic" under some awesomeness that are provided by frameworks or libraries. Although they are good for quicker development, there is good to think a little bit more about how and when use it when we have a software that we aim to last longer and get to the phase of greater maintainability.

É uma maneira bastante eficaz para tarefas repetitivas que precisam rodar em segundo plano, como o envio de notificação, backup de banco de dados, entre outras.

Howto: use one VCL per domain

The Varnish Configuration Language (VCL), I'm sure you know already, is the source of Varnish versatility: by only enforcing the protocol flow and leaving the business logic to the user, Varnish can be easily configured to do things far beyond caching.

However, because the logic of websites is generally focused around hosts, and the VCL thinks in terms of processing steps, configuration may sometimes a bit odd, with the need to place safeguards around your code to ensure that logic for one host isn't applied to another one.

It works, but it can be tedious and unwieldy, so today we are going to have a look at how we can silo our VCL per website to achieve better maintainability.

Understanding the 8 Fallacies of Distributed Systems

Are you working on a distributed system? Microservices, Web APIs, SOA, web server, application server, database server, cache server, load balancer - if these describe components in your system's design, then the answer is yes. Distributed systems are comprised of many computers that coordinate to achieve a common goal.

More than 20 years ago Peter Deutsch and James Gosling defined the 8 fallacies of distributed computing. These are false assumptions that many developers make about distributed systems. These are usually proven wrong in the long run, leading to hard to fix bugs.
