Deploy your apps using Google Cloud service, App Engine. It is server-less service for deploying apps. You don't need worry about hardware, installation, operation and maintenance. You only focus with your business and application.

7. What is App Engine?
Service for building highly
scalable applications on a fully
managed serverless platform by
Google Cloud.
“Scale your applications from zero to planet
scale without having to manage
infrastructure”

8. What is Serverless?
 No upfront provisioning
 No management of servers
 Pay only what you use
 Dynamically scale as needed

9. App Engine Key Feature
1. Fully managed environment (lets you focus on code).
2. Automatic load balancing, and scaling.
3. Application versioning, and traffic splitting.
4. Custom runtimes allow to bring any library and
framework.
5. Manage resources from the CLI, debug source code,
and run API.

10. App Engine Structure
& Configuration

11. Region
Specific geographical location where you can host your resources. Regions
have three or more zones.

12. App Engine Structure
GCP Project

13. Setting Configuration via app.yaml
File that contains information
about app's settings, which
acts as a descriptor for its
deployment.

14. Setup App Engine Application on
Project
Setup application first using
Console, Google Cloud SDK,
or Cloud Shell. GCP Project

15. GCP Project
Deploy Application on App Engine
Deploy app using Google
Cloud SDK/Cloud Shell.

16. Deploy New Versions
gcloud app deploy --version=v1-2 --no-
promote
--no-promote
to deploys
without routing
to new version

17. Migrate Traffic Between Versions
gcloud app services set-traffic service --splits

--migrate
to gradually
migrate traffic

19. Resource Scaling
•Automatic
• Creates
instances based
on request rate,
response
latencies, and
other metrics.
• You can specify
thresholds for
the metric and
min instances.
Basic
• Creates
instances when
your app
receives
requests.
• Each instances
will be shut
down when the
app becomes
idle.
Manual
• Specifies the
number of
instances that
continuously run
regardless of the
load level.

20. App Engine Standard vs Flexible

21. Standard
• Application instances run in a sandbox.
• Specific versions of the supported
programming languages, i.e. Python 2.7 &
3.7-3.9, Java 8 & 11, Node.js 10, 12, 14,
16, PHP 5.5, 7.2-7.4, Ruby 2.5-2.7, Go
1.11-1.16.
• Run for free at limited quota or at very low
cost.
• Sudden and extreme spikes of traffic.
Flexible
• Application instances run within Docker
containers on Compute Engine.
• Any version of the supported programming
languages, i.e. Python, Java, Node.js, Go,
Ruby, PHP, or .NET.
• Custom runtime or source code written in
other programming languages.
• Accesses the resources that reside in the
Compute Engine network.

22. Feature Comparison
Feature Standard Flexible
Instance startup time Seconds Minutes
Deployment time Seconds Minutes
Scaling Manual, Basic, Automatic Manual, Automatic
Scale to zero Yes No, minimum 1 instance
SSH debugging No Yes
Writing to local disk Write access to
the /tmp directory except
Python 2.7 and PHP 5.5
Yes, ephemeral (disk
initialized on each VM
startup)
Installing third-party binaries Limited Yes
