I\u2019ve been a developer\/architect for most of my professional life, mainly in the Java\/Spring ecosystem. Even at that time, I was interested in the other side: operating, monitoring, etc. what today would be called DevOps. Last year, I steered my career in another direction and became a Developer Advocate.<\/span><\/p>\n<p><span style=\"font-weight: 400\">I\u2019m working for a company called <\/span><a href=\"https:\/\/www.exoscale.com\/\"><span style=\"font-weight: 400\">Exoscale<\/span><\/a><span style=\"font-weight: 400\">. We are a European Cloud Provider, offering Infrastructure-as-a-Service resources. There\u2019s no denying Cloud hosting is gaining a lot of traction, and the microservices architecture is particularly well-suited to Cloud hosting. Hence, using my experience as a developer, I worked a lot on the integration of different themes that make sense together: configuration management, resilience across services, logging, monitoring, etc.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><b>What will you be talking about at Voxxed Days Microservices?\u00a0<\/b><\/p>\n<p><span style=\"font-weight: 400\">My talk is about resilience: when one migrates from a standard API call to a service call, one can easily believe in the fallacies of distributed computing. Chief among those fallacies is \u201cthe network is reliable\u201d. Hence, for some reason, the required service could be unavailable. Fortunately, there\u2019s the timeout; unfortunately, if the caller needs to wait for the timeout, chances are it\u2019s going to be flooded by requests, and be unavailable itself.<\/span><\/p>\n<p><span style=\"font-weight: 400\">In those kinds of architecture, a failure can quickly propagate all over the place, and put the whole system down. For that reason, smart people came up with the Circuit Breaker pattern. Just like a household circuit-breaker protects the electrical system from power surges, the pattern protects the architecture. However, one must be careful as \u201cCircuit Breaker\u201d is quite a general term. Libraries implement it, service meshes implement it. Those are not interchangeable!\u00a0<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><b>Microservices architecture are using more and more asynchronous messaging and streaming, therefore circuit breakers tend to decline. Do you see a trend here, what about the future of the circuit breaker pattern ?\u00a0<\/b><img loading=\"lazy\" class=\" wp-image-1999 alignright\" class=\"lazyload\" data-sizes=\"auto\" data-srcset=\"https:\/\/i1.wp.com\/voxxeddays.com\/microservices\/wp-content\/uploads\/sites\/54\/2019\/07\/Capture-d\u2019e\u0301cran-2019-07-15-a\u0300-15.59.13-300x187.png?w=75&resize=75 75w, https:\/\/i1.wp.com\/voxxeddays.com\/microservices\/wp-content\/uploads\/sites\/54\/2019\/07\/Capture-d\u2019e\u0301cran-2019-07-15-a\u0300-15.59.13-300x187.png?w=100&resize=100 100w, https:\/\/i1.wp.com\/voxxeddays.com\/microservices\/wp-content\/uploads\/sites\/54\/2019\/07\/Capture-d\u2019e\u0301cran-2019-07-15-a\u0300-15.59.13-300x187.png?w=150&resize=150 150w, https:\/\/i1.wp.com\/voxxeddays.com\/microservices\/wp-content\/uploads\/sites\/54\/2019\/07\/Capture-d\u2019e\u0301cran-2019-07-15-a\u0300-15.59.13-300x187.png?w=240&resize=240 240w, https:\/\/i1.wp.com\/voxxeddays.com\/microservices\/wp-content\/uploads\/sites\/54\/2019\/07\/Capture-d\u2019e\u0301cran-2019-07-15-a\u0300-15.59.13-300x187.png?w=320&resize=320 320w, https:\/\/i1.wp.com\/voxxeddays.com\/microservices\/wp-content\/uploads\/sites\/54\/2019\/07\/Capture-d\u2019e\u0301cran-2019-07-15-a\u0300-15.59.13-300x187.png?w=500&resize=500 500w, https:\/\/i1.wp.com\/voxxeddays.com\/microservices\/wp-content\/uploads\/sites\/54\/2019\/07\/Capture-d\u2019e\u0301cran-2019-07-15-a\u0300-15.59.13-300x187.png?w=640&resize=640 640w, https:\/\/i1.wp.com\/voxxeddays.com\/microservices\/wp-content\/uploads\/sites\/54\/2019\/07\/Capture-d\u2019e\u0301cran-2019-07-15-a\u0300-15.59.13-300x187.png?w=800&resize=800 800w, https:\/\/i1.wp.com\/voxxeddays.com\/microservices\/wp-content\/uploads\/sites\/54\/2019\/07\/Capture-d\u2019e\u0301cran-2019-07-15-a\u0300-15.59.13-300x187.png?w=1024&resize=1024 1024w, https:\/\/i1.wp.com\/voxxeddays.com\/microservices\/wp-content\/uploads\/sites\/54\/2019\/07\/Capture-d\u2019e\u0301cran-2019-07-15-a\u0300-15.59.13-300x187.png?w=1280&resize=1280 1280w, https:\/\/i1.wp.com\/voxxeddays.com\/microservices\/wp-content\/uploads\/sites\/54\/2019\/07\/Capture-d\u2019e\u0301cran-2019-07-15-a\u0300-15.59.13-300x187.png?w=1600&resize=1600 1600w\" data-src=\"https:\/\/i1.wp.com\/voxxeddays.com\/microservices\/wp-content\/uploads\/sites\/54\/2019\/07\/Capture-d\u2019e\u0301cran-2019-07-15-a\u0300-15.59.13-300x187.png\" alt=\"\" width=\"302\" height=\"188\" srcset=\"https:\/\/i1.wp.com\/voxxeddays.com\/microservices\/wp-content\/uploads\/sites\/54\/2019\/07\/Capture-d\u2019e\u0301cran-2019-07-15-a\u0300-15.59.13-300x187.png 300w, https:\/\/voxxeddays.com\/microservices\/wp-content\/uploads\/sites\/54\/2019\/07\/Capture-d\u2019e\u0301cran-2019-07-15-a\u0300-15.59.13-160x100.png 160w, https:\/\/voxxeddays.com\/microservices\/wp-content\/uploads\/sites\/54\/2019\/07\/Capture-d\u2019e\u0301cran-2019-07-15-a\u0300-15.59.13.png 405w\" sizes=\"(max-width: 302px) 100vw, 302px\" \/><\/p>\n<p><span style=\"font-weight: 400\">My personal opinion is that one should be very cautious about trends. Most companies do use microservices. Even worse, most companies are even hardly suited to use them. I love this image from Martin Fowler\u2019s blog:<\/span><\/p>\n<p><span style=\"font-weight: 400\">Microservices offer a lot of benefits, but also have very strong requirements. Most people only see the benefits, and conveniently forget about the requirements&#8230; until they come to bite them where it hurts. Likewise, asynchronicity makes it harder to reason about the code, and increases by a non-trivial amount the workload in two areas related to software development: debugging and testing.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">I\u2019m a big fan of continuous improvement myself and I believe that trying to implement asynchronous microservices from day 1 is a sure recipe for disaster. Remember that Twitter started with Ruby on Rails. This pragmatic no-nonsense way should be the way to go for every company which wants to be successful. Start with a monolith, then if necessary, migrate to macro-services, then refine them (if necessary) to microservices, then introduce asynchronicity where it makes sense, etc.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><b>Good, see you soon then\u00a0<\/b><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400\">#devops #resilience #circuitbreaker<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><b>My contact information<\/b><\/p>\n<p><span style=\"font-weight: 400\">Twitter: <\/span><a href=\"https:\/\/twitter.com\/nicolas_frankel\"><span style=\"font-weight: 400\">https:\/\/twitter.com\/nicolas_frankel<\/span><\/a><\/p>\n<p><span style=\"font-weight: 400\">Blog: <\/span><a href=\"https:\/\/blog.frankel.ch\/\"><span style=\"font-weight: 400\">https:\/\/blog.frankel.ch\/<\/span><\/a><\/p>\n<p><span style=\"font-weight: 400\">GitHub: <\/span><a href=\"https:\/\/github.com\/nfrankel\"><span style=\"font-weight: 400\">https:\/\/github.com\/nfrankel<\/span><\/a><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Hi Nicolas, tell us who you are and what lead you into microservices?
