Gluttony is the overindulgence and overconsumption of anything to the point of waste.

Memory, Disk, Network

people arguing against fat JARs (only ship the business logic), but perfectly ! ne with containers - shipping even the JVM ! #RigaDevDays — https://twitter.com/xeraa/status/864122131768119296

640K ought to be enough for anybody

Microservices Nano, Pico, Femto, Atto, Yocto

Don’t forget - having legacy software is often a sign of success. Your business was successful to last long enough for your software to become legacy. — https://twitter.com/samnewman/status/ 929622273065136130

Yes, it helps if too many people too many dependencies not scalable

SOA done right?

We replaced our monolith with micro services so that every outage could be more like a murder mystery. — https://twitter.com/honest_update/status/ 651897353889259520

Here's a diagram of two microservices and their shared database. — https://twitter.com/mathiasverraes/status/ 711168935798902785

OH: "replace your shared monolithic DB with a shared monolithic stream store" — https://twitter.com/ntcoding/status/928902644764200960

...don’t even consider microservices unless you have a system that’s too complex to manage as a monolith. The majority of software systems should be built as a single monolithic application.

Do pay attention to good modularity within that monolith, but don’t try to separate it into separate services. — http://martinfowler.com/bliki/MicroservicePremium.html

If you want to implement microservices, the 1st thing you need to do is implement aggregated logging. The 2nd is implement correlation IDs — https://twitter.com/samnewman/status/ 862255875125366786

Microservices can help large number of people go faster by allowing more autonomy. I remain to be convinced it does the same for small teams — https://twitter.com/samnewman/status/ 778118760226062336

Containerizing legacy applications

Microservices + containers Cargo cult

cargo culting comes from received but not integrated knowledge.because one doesn't grasp how a thing works, one simply goes through the motion of how one was told to do it. — https://twitter.com/GeePawHill/status/ 931941663886454784

If you are only picking Kubernetes because that's the way Google does it, then you should also consider writing your own ! lesystems. — https://twitter.com/kelseyhightower/status/ 741310392756887552

We've been so beaten into thinking we need to care about the speed-of- delivery with containers, we lost focus somewhere on prod reliability — https://twitter.com/danveloper/status/858372256174669824

What's wrong here? For a stateful production service $ docker run -p 9200:9200 -p 9300:9300 -e "http.host=0.0.0.0" -e "transport.host=0.0.0.0" -e "discovery.zen.ping.unicast.hosts=..." docker.elastic.co/elasticsearch/elasticsearch
