API gateway and Load Balancer Integration is very vital to render scalable and robust infrastructure. The API gateway is the first point of contact for the internet and protocol-specific traffic, the api gateway is the gateway where user identity, TLS offloading, metrics, and traffic monitoring takes place.
The API gateways are integrated with WAF; WEB ACCESS FIREWALL is a very vital component of the API Gateway that ensures the safety and security of the systems that are part of web infra. WAF keeps the malicious and black hat traffic at bay and ensures the systems are safe and secure at all times.
The load balancer will handle the packets sent through the API gateways. The packets can be either HTTPS or HTTP-based. If the TLS offloading is activated, then the traffic handled by the load balancer will be HTTP-based. Both Api gateway and Load balancer are tightly coupled with each other in distributed systems to ensure HQ traffic flow without packet loss.
Nowadays, API gateways and load balancing work together to handle workloads at scale. This promotes higher efficiency, cost-effectiveness, and lower latency.
The load Balancer will have auto-scaling groups, the auto scaling groups consist of healthy servers that will be able to take the workload once the servers hit a certain threshold, the auto scaling group needs to be assigned as manual scaling can induce latency and error during real-time operations and real-time load, it is always advised to keep the load balancing system automated and assign right set of auto-scaling groups to ensure smooth operation and lower failure over rates.
In short, the API gateways will pass the sanitized traffic to the load balancer which will then send the traffic to the targets; the targets are services, APIs, containers services, serverless infra, Servers, H/W devices, etc.
API GATEWAY —> LOAD BALANCER —> AUTO-SCALING GROUP –> HEALTH SERVER POOL (traffic redirection)
NOTE: The gateway load balancer will direct packets to other systems for further processing, such as IPS, firewalls, packet inspectors, and packet manipulators.
