Modern Apps Require a Modern Architecture
What holds you back… … and propels you forwards
Three-tier, J2EE-style architectures
Complex, formal protocols (HTML, SOAP)
Persistent deployments
Fixed, static Infrastructure
Big-bang releases
Silo’ed teams (Dev, Test, Ops)
Microservices
Lightweight, informal (REST, Messaging)
VMs, Containers, Functions
Infrastructure as Code
Continuous Integration / Continuous Delivery
DevOps Culture

Reality Check…When the Cloud not right for you?
• You have sufficient resource and expertise to host services yourself; Cloud
may be more expensive
• Compliance Reasons mean data must remain on-premises
• Cloud Provider can’t meet your internal security or forensics requirements
• You’re not comfortable with the SLA provided for critical apps
• Your application is hardware-bound, or has performance requirements that
can’t be met on the cloud (e.g. it can only be scaled vertically)
![Page 18: Driving Success in the cloud with NGINX - Amazon Web …...• “Set up a highly available, secure AWS environment, and launch NGINX Plus automatically to load-balance scalable webapps”](https://reader034.vdocuments.site/reader034/viewer/2022042221/5ec7f4530874e9695b486b13/html5/thumbnails/18.jpg)
Moving to the Cloud with NGINX

Why use NGINX in cloud environments?
• It’s lightweight – requires very little CPU/Memory
• It’s portable – it will run anywhere
• It’s easy to deploy and configure
• It’s rock-solid reliable
• It’s the HTTP endpoint of choice for many of the world’s
biggest, most high-profile services

Begin with a partial migration?

Begin with a partial migration
• Use Different Domains◦ Clients connect directly to the
location of the service they are
using
• Use X-Accel-Redirect◦ All traffic is handled through the
same NGINX cluster, and
internally routed to cloud
• You need to route traffic to the correct datacenter:
![Page 22: Driving Success in the cloud with NGINX - Amazon Web …...• “Set up a highly available, secure AWS environment, and launch NGINX Plus automatically to load-balance scalable webapps”](https://reader034.vdocuments.site/reader034/viewer/2022042221/5ec7f4530874e9695b486b13/html5/thumbnails/22.jpg)
X-Accel-Redirect• A more sophisticated alternative to a simple
proxy_pass
• Request goes to local server
• Local server internally redirects to remote
server
Ideal for moving content to cloud storage or
serverless, while retaining NGINX-based
authentication and logging .
Client can never access remote server directly.

Now focus on the cloud…

![Page 24: Driving Success in the cloud with NGINX - Amazon Web …...• “Set up a highly available, secure AWS environment, and launch NGINX Plus automatically to load-balance scalable webapps”](https://reader034.vdocuments.site/reader034/viewer/2022042221/5ec7f4530874e9695b486b13/html5/thumbnails/24.jpg)
How do we deploy NGINX HA in a cloud?
Four methods:
• External DNS-based load balancing – GSLB
• Use Cloud Provider’s load balancer
• Keepalived with Elastic IP addresses
• External serverless monitoring (AWS Lambda)
![Page 25: Driving Success in the cloud with NGINX - Amazon Web …...• “Set up a highly available, secure AWS environment, and launch NGINX Plus automatically to load-balance scalable webapps”](https://reader034.vdocuments.site/reader034/viewer/2022042221/5ec7f4530874e9695b486b13/html5/thumbnails/25.jpg)
Sometimes the Cloud Load Balancer does not cut it…
• NGINX developed Keepalived and Serverless monitoring
solutions because sometimes AWS CLB or ALB could not
meet users’ needs:
◦ Reliance on Route53 for DNS; necessary for root domain names
◦ Can be slow to scale, dropping traffic, when traffic levels increased
◦ Often needed to fall back to TCP-based load balancing
![Page 26: Driving Success in the cloud with NGINX - Amazon Web …...• “Set up a highly available, secure AWS environment, and launch NGINX Plus automatically to load-balance scalable webapps”](https://reader034.vdocuments.site/reader034/viewer/2022042221/5ec7f4530874e9695b486b13/html5/thumbnails/26.jpg)
