NGINX is the best-in-class load balancing solutions used by high-traffic websites such as Dropbox, Netflix, and Zynga. This is a presentation describing about Load balancing microservices running over container using Nginx, it's use cases and simple configuration.

1. Load Balancing Container with
Nginx
PRESENTED BY:
KUMAR MAYANK
GUIDED BY:
MRS.NEENA ELSA JOSE PRAKASH

2. OverView:
• Containerization
• Handling HTTP Request
• Load Balancer
• Nginx
• Nginx Implementation
• Configuring the Nginx
• Demonstration
• Nginx major clients
• Conclusion
• Reference

3. CONTAINERIZATION
• Containerization is a lightweight alternative to full
machine virtualization that involves encapsulating an
application in a container with its own operating
environment.
• Docker containers are designed to run on everything
from physical computers to virtual machines, bare-
metal servers, OpenStack cloud clusters, public
instance and more.

4. CONTAINERIZATION
• Abstraction of the host system away from the
containerized application.
• Extremely lightweight, isolated execution
environments.
• Simple Dependency Management and Application
Versioning

5. Handling HTTP Request

6. Server
Default port no.: 80
client

7. server
clients
• Increasing load on a single
server.
• Less reliable

8. SOLUTION:
• Load Balancing using multiple Duplicate server.
CHALLENGE:
• Each server will have it’s unique IP.
• Handling multiple IPs.

9. LOAD BALANCER
• Load balancing refers to efficiently distributing
incoming network traffic across a group of backend
servers, also known as a server farm or server pool.
• Distributes client requests or network load efficiently
across multiple servers

10. LOAD BALANCER (cont..)
• Ensures high availability and reliability by sending
requests only to servers that are online
• Provides the flexibility to add or subtract servers as
demand dictates

11. NGINX:
NGINX was written by Igor Sysoev, a Russian
system and software engineer. From the very beginning
NGINX was created with a vision on how the pressure
for content and the increasing number of web and
mobile users will transform the essential infrastructure
elements used by the Internet focused companies.

12. NGINX:
NGINX has been really successful with customers in
a Variety of market areas which include Service
providers, Media & Entertainment, Online Retail, Social
Media and more.
Today over 10% of the top 1,000,000 Internet web
sites and 25% of the top 1,000 web sites run on NGINX,
including Groupon, LivingSocial, Playdom, Zappos,
Hulu, TechCrunch, Dropbox, Yandex, WordPress and
many others.

13. NGINX:
• NGINX is the best-in-class load balancing solutions
used by high-traffic websites such as Dropbox, Netflix,
and Zynga.
• As a software-based load balancer, NGINX is much
less expensive than hardware-based solutions with
similar capabilities.
• The comprehensive load balancing capabilities in
NGINX enables to build a highly optimized application
delivery network.

14. NGINX: (cont..)
The following load balancing mechanisms (or methods) are supported
in nginx:
• round-robin — requests to the application servers are distributed in
a round-robin fashion,
• least-connected — next request is assigned to the server with the
least number of active connections,
• ip-hash — a hash-function is used to determine what server should
be selected for the next request (based on the client’s IP address).

15. Default Nginx load balancing configuration:
The simplest configuration for load balancing with nginx may look like
the following:

16. Nginx Implementation:

17. Multiple
servers
Multiple
clients
NGINX server
• Default port no.: 80

18. Configuring the Nginx

19. Configuring the Nginx
• Create Container for Nginx server
• Start Nginx server Container
• Attach Nginx server Container

20. Configuring the Nginx
• Install Nginx web server
• Open Nginx Configuration file

21. Configuring the Nginx
• Configuration:
• Start or Restart Nginx Service

22. Demonstration :

23. NGINX users:

24. Conclusion:
• NGINX has the lowest memory footprint possible and
optimizes CPU usage while delivering maximum
performance even on a very inexpensive server
hardware.
• NGINX supports all the major standards and
protocols, providing the set of features necessary
today to build a scalable web setup.
• NGINX configuration is logical and flexible and allows
more efficiency and scalability in day-to-day
engineering.
