49. PLATFORM FOR CREATING WEB SERVICES
50. THE APP ENGINE WAY
51. THE "CLOUD" WAY
52. LIMITATIONS* can't write in the local disk 60secs deadline to respond to requests 10mins deadline for background threads limited to 1 CPU thread even for concurrent PLs can't customize the serving stack doesn't support installing 3rd party binaries some PL features can’t be used
53. HOW DO YOU MAKE YOUR WEB APP THRIVE IN THE "CLOUD"?
54. STATELESS
55. MICROSERVICES (Recommended)
56. SCALABLE
57. GAE IS A ONE-STOP SHOP FOR EVERYTHING WEB DEV
58. Support for Google Auth Memcache API Cron jobs Task queues Search API (Python, Java and Go) Logs API Image API (Python, Java and Go) Mail API URL Fetch service Sockets API Cloud Storage Cloud Datastore
59. CLOUD DATASTORE
60. DENORMALIZE DATA
61. LESSEN WRITE FREQUENCY Consider all remote ops slow Reads are turbo fast (constant speed corresp result size)
62. INSTALLING GOOGLE APP ENGINE
63. Download the Cloud SDK from https://cloud.google.com/sdk/
64. Extract the archive, move google-cloud-sdk somewhere
65. Run install.sh to con gure $PATH and command completions
66. Open a new shell, run gcloud components list to get a list of available App Engine extensions
67. gcloud components install one of these to start
68. PHP IN GAE PHP 5.5
69. MOST FRAMEWORKS ASSUME USE OF A RELATIONAL DATABASE Frameworks are tightly coupled to the data
70. CLOUD SQL ISN'T FREE
71. AT LEAST TRY USING CLOUD DATASTORE
72. GOOGLE CLOUD DATASTORE LIBRARY https://github.com/tomwalder/php-gds
73. Zend Expressive Silex Slim Any router package (PHP by itself is already a web framework!) FastRoute klein.php https://zendframework.github.io/zend- expressive/ http://silex.sensiolabs.org/ http://www.slimframework.com/ https://packagist.org/packages/nikic/fast- route https://packagist.org/packages/klein/klein
74. TIP IT'S 2016, USE COMPOSER!
75. PYTHON IN GAE Python 2.7
76. VENDORING You can still use pip
77. Python libs with C extensions won't work # appengine_config.py from google.appengine.ext import vendor # Add any libraries install in the "lib" folder. vendor.add('lib') To install third-party libs.. $ # project root $ pip install -t lib <package>
78. Ferris Framework Djangae Flask http://ferris-framework.appspot.com/ http://djangae.org/ http:// ask.pocoo.org/
79. GO IN GAE Go 1.6
80. MISSING LINKS ON LATEST SDK BUILD $ # Warning: Temporary fix! $ cd <sdk-location>/bin $ ln -s ../platform/google_appengine/goapp .
81. GAE SDK SETS ITS OWN GOROOT
82. AND INHERITS THE SYSTEM'S GOPATH
83. BUILD CONSTRAINTS // +build appengine // +build !appengine
84. HYBRID APP THAT RUNS STANDALONE OR IN APP ENGINE
85. app.go package main import ( "fmt" "net/http" ) func init() { http.HandleFunc("/", handler) } func handler(w http.ResponseWriter, r *http.Request) { fmt.Fprint(w, "DevFest Baguio in Go!") }
86. main.go // +build !appengine package main import "net/http" func main() { http.ListenAndServe("localhost:8080", nil) }
87. Datastore import "google.golang.org/appengine/datastore"
88. JAVA IN GAE Java 7

96. ENVIRONMENT TYPES STANDARD vs FLEXIBLE
97. STANDARD Go 1.6 Java 7 PHP 5.5 Python 2.7
98. FLEXIBLE Node.js Python 2.7 & 3.4 Ruby Go PHP Java .NET x y.z (Custom Runtime)
99. DATASTORE EMULATOR https://cloud.google.com/datastore/docs/tools/datastore- emulator
100. TAKEAWAYS
