In the previous parts, we discussed the basics of networking on AWS, setting up and configuring a VPC on AWS, advanced networking concepts on AWS, best practices for networking on AWS, and monitoring and troubleshooting networking on AWS. In this part, we will discuss some common networking use cases on AWS.
Load Balancing
Load balancing is a common networking use case on AWS. You can use Elastic Load Balancing (ELB) to distribute incoming traffic across multiple instances in a single availability zone or across multiple availability zones.
ELB automatically routes traffic to healthy instances and monitors the health of instances. This ensures that traffic is always routed to healthy instances and that your application remains available in the event of an instance failure.
Highly Available Applications
Another common networking use case on AWS is creating highly available applications. To create highly available applications, you can use multiple availability zones, Amazon Route 53, and Elastic Load Balancing.
By using multiple availability zones, you can ensure that your application remains available in the event of an outage in one availability zone. Amazon Route 53 allows you to route traffic to healthy instances in multiple availability zones, while Elastic Load Balancing distributes incoming traffic across multiple instances.
This ensures that your application remains available and performs well, even in the event of an instance failure or an outage in one availability zone.
Private Connectivity
Private connectivity is another common networking use case on AWS. You can use Amazon VPC peering to connect multiple VPCs and enable private connectivity between them.
Amazon VPC peering allows you to connect VPCs in the same region or in different regions. This enables you to create a secure and private network between multiple VPCs and share resources and data between them.
Conclusion
In conclusion, load balancing, highly available applications, and private connectivity are common networking use cases on AWS. By using tools and services such as Elastic Load Balancing, Amazon Route 53, and Amazon VPC peering, you can create highly available and secure architectures for your applications on AWS.
It is also essential to keep up-to-date with the latest features and best practices on AWS to ensure that your deployment remains secure and compliant with industry standards. By following these best practices and using these common networking use cases, you can create a highly available and secure architecture for your applications on AWS.
