[GAE now] After all, I participated in AppEngine ja night # 1 so I summarized it.

After all AppEngine ja night # 1 by GCPUG @ Nikkei Conference Room

Did you go to a GAE event? My friends love memos! (I don't call it Tokui)

For those who only know the name of GAE Personally, I will list the good points of Google App Engine, the strongest PaaS platform ↑ It may be better to read around first ʕ • ̀ω • ́ʔ✧

Greetings from Kazunori

appengine ja night #1-#10 review @ kazunori279

The flow of the event so far What if the space-filling curve looks like this?

Google App Engine Now and Old ~ GAE Prosperity, Decline and Revival ~

GAE Tsuyomi

** Autoscale, versioning is the default ** It's hard to do with IaaS! ** Use Google Infrastructure **

Rekishi!

Year Additional features Supplement
2008 (Announced at Campfire one) There were many restrictions at first
2009 Paid version
Memcache, Admin Console, image API,
GAE/J, Cron,
TaskQueue, XMPP, Blobstore
This time is the most popular
GAE/J
slim3 used
 Scala, Groovy,The appearance of JRuby is about to happen
Spring Roo,VMWare → There was neither ...
2010 Datastore Cursor, AppStats, Namespace
2011 GAE/Go, backends,
High Reprication Datastore
Price revision (generally price increase)
Price revision CPU time → Instance time
I was hit. It was still cheaper than other PaaS ...
One cause of decline
2012 Channel API, ndb,
Go 1.0, Threads,
GCS, Search API, GCE
ndbIs a masterpiece of Mr. Guido
It was quite developed
2013 socket, php, cloud endpoint,
dedicated memcache, cloud playground
cloud playgroundIs easy
Saikin Relaxation of restrictions, price revision (generally price reduction),
Supports multiple languages within the project
Price revision
Datastore I don't have to worry too much
Think only when you're speeding

The heyday (-2011)

It was cheap, it was cusso scaled, and it was the most played

But the problem is highlighted

Spin-up Java slow (because Java was the most used) supported language Lock-in File system cannot be used Unusable API gar Price revision from (generally price increase)

But it kept evolving

It has become stable with a good feeling (2012-)

HRD (High Replication Data store) has no obstacles The limit is gradually relaxed (in the past, up to 1000 Datastores) Documents have also increased

GCP as a whole

SQL is now available, and big queries are all the rage Various mysterious technologies

GAE Flexible Environment β It's nice to have more freedom, but the back side has changed a lot and it's still stable. It's not GAE anymore (just that)

The times have caught up with GAE! (Now)

Popularization of containers "I was sick" Autoscale has become common sense Fully managed Good flow Lock-in What is it delicious (Oh yeah w) Good compatibility with the recently popular Go

Language comparison

(In Standard Edition)

language Spin up Library Supplement
Python Fast Many good taskletCan be parallelized by using
Lots of Google sample code
Go Detonation velocity Somewhat late Goruchin!
SDK version will follow you for the time being
Java Late As it is Don't worry about hiring
Easy to receive IDE support
slim3 Not recently updated ...
PHP Fast Less Shirane(゜ ⊿ ゜)
Rumors with Onimon

Around the recent GAE

Please note that there is a lot of outdated information ndb, HRD, Services (formerly Modules) are not available

The development of GAE alone is slow. Follow GCP as a whole Machine learning API, Stackdriver, Firebase, etc. ** Tokyo Region ** ktkr Nexuto wktk

Easy to develop with Stackdriver system  Debugger, Trace, Logging

Datastore is not good for anything (old people tend to do it) It's hard for strangers, and now I have Cloud SQL If you want to use it, ask someone who has knowledge. There is a design, it is deep ** @ sinmetal [seems to write] in the technical book of Technical Book 2 (https://twitter.com/sinmetal/status/837522065179566081) ** Yeah?

Practice of multi-tenant web application using Namespace API

(Banner distribution tool that spans multiple services) https://www.slideshare.net/takuyaueda967/namespace-apiweb @tenntenn

(reference) Atte Development Technology: Golang and Google App Engine

Requirements

The language used by Mercari Atte and Mercari is PHP Interference, no specific processing for each service Also used by non-engineers Easy to get rid of

NamespaceAPI For use from multiple apps Settings for each service do not apply to data and code Supports datastore, memcache, TaskQueue, Search

Still

Just look at the Context! There is no function to get Namespace (!), So I wrapped it.

Switch to Namespace with middleware and save in datastore Use the instance part of the URL as a Namespace (use it to ignore other than numbers)

Unify the administrative Namespace Administrative API requires administrator privileges

Handling on the console

datastore namespace and type What to do if memcache namespace is local ...?

Summary

Pros No effect on other services Development environment can be created immediately As soon as you create a Namespace Disadvantages API required for configuration migration between Namespaces Troublesome local debugging

** Easy multi-tenant with GAE ** ** Making in-house tools with GAE is a good idea ** Access control is easy to use in G suite

The strongest PaaS environment Google App Engine

https://speakerdeck.com/yosukesuzuki/appengine-at-nikkei @yosukesuzuki

(reference) Personally, I will list the good points of Google App Engine, the strongest PaaS platform

Nikkei electronic version 500,000 paying members, 300 million monthly

200 requests / sec about 1 million / day ** Usage fee 40-50,000 / month ** Half is out of the internet 6 people if the time difference is large when it comes 3-26 instances

** It's okay to play abandoned ** The big obstacle is about October 2012 in the last 5 years

When I try to do it on AWS (Elastic Beanstalk) ...

No blue-green deployment, slow container startup Jenkins, Rundeck, Sentry, New Relic, etc. are required (= people who can use it are also required)

Future expectations

py3 yet? Search Subtle? Do not scale Difficult to get out of CI

Beer talk

~~ I can't say I didn't make a note even though I like my friends ~~

Try using Vision API / Translation API from GAE

https://github.com/GoogleCloudPlatform/appengine-photoalbum-example enakai00

You can make this kind of thing in less than 200 lines, so by all means

I tried to contribute to the community without permission with GAE

http://www.バ蒲田ニュース.jp/ @tomorier   If you inadvertently try to make Kamata a fool on Twitter, you will have to see Kamata's wonderful information by being fooled, which is a terrifying service.

A story made by Reversi LINE Bot on GAE / Go

https://docs.google.com/presentation/d/1iJHJsRaSgLDU6d0Dqtcs-FVtKEzLzMlfji4MfLPC6NY/edit#slide=id.p @orfeon

LINE API Link in the image With the free version, you can only do 50 places, but it's enough because you only need to hit the hand

Is GAE / Go + Cloud SQL in Demand?

https://github.com/kaneshin/playground/tree/master/gae/go-cloudsql @kaneshin (reference) Go + App Engine + Cloud SQL-based Go language web application development

** Where are you addicted to Cloud SQL 2nd gen! ** ** Specified in the format " project: region: instance " in app.yaml https://cloud.google.com/appengine/docs/standard/go/cloud-sql/#setting-up

I tried GAE in China

https://www.slideshare.net/HayatoYoshikawa/how-to-make-gae-adapt-the-great-firewall @hayatoy

The idea was not

GAE on Scala

@mtoyoshi

I'm doing my best now! It looks like a place We are waiting for good news

Summary

Even if there are quite a lot of access ** quite cheap ** Moreover, it doesn't need any care **, and it's GAE. (Functionally and community-wise) ** The environment is ready ** Now is the time   Expect ** Datastore design articles ** in tech books ~~ Or rather, it's surprising that @sinmetal didn't take the stage ~~

Also ** Pizagochisosa (๑´ڡ`๑) **
