Metric collection. If you enable cross-zone load balancing, each load balancer node routes requests to the healthy targets in all enabled Availability Zones. You add one or more listeners to your load balancer. CloudWatch enables you to retrieve statistics about those data points as an ordered set of time-series data, known as metrics. Security scalability, meet cloud simplicity. Network Load Balancer is now able to terminate TLS traffic and set up connections with your targets either over TCP or TLS protocol. For network acceleration, AWS Global Accelerator provides static IP addresses that act as a fixed entry point to your application endpoints in AWS. A load balancer serves as the single point of contact for clients. AWS Global Accelerator vs Amazon CloudFront In this day and age, your site speed performance is an important factor when it comes to user experience. Network Load Balancer routes traffic to targets within Amazon VPC and is capable of handling millions of requests per second while maintaining ultra-low latencies. Amazon Elastic Load Balancing (ELB) allows websites and web services to serve more requests from users by adding more servers based on need. Additional hops within your cloud network such as load balancers, WAF protection, and jumps between multi-tiered app layers. The just-announced general availability of the integration between VM-Series virtual firewalls and the new AWS Gateway Load Balancer (GWLB) introduces customers to massive security scaling and performance acceleration – while bypassing the awkward complexities traditionally associated with inserting virtual appliances in public cloud environments. ELB Load Balancing Traffic Latency. The AWS Application Load Balancer - Latency Details dashboard provides insights into client latency by domain and ELB server, as well as processing times by ELB server and target groups throughout your infrastructure. So that sort of gives a baseline on what TLS latency can be when network is fast. 5. AWS recently announced a new Load Balancer called as Network Load Balancer(NLB). With this new capability, enterprises can now deploy services that rely on UDP protocol such as Authentication and authorization, Directory, Logging, DNS, IoT and Streaming media (audio and video) behind Network Load Balancer benefiting from its low latency, scale, and reliability. Think of a metric as a variable to monitor, and the data points as the values of that variable over time. This was accompanied by a rename of the previous… Metric Description; ActiveFlowCount: The total number of concurrent flows (or connections) from clients to targets. If you haven’t already, set up the Amazon Web Services integration first. For example, when the user in Germany measures latency over the same connection by repeatedly downloading a 10 MB file, the average latency for Network Load Balancing is 1911 ms compared to 1341 ms with HTTP(S) Load Balancing… Use a Network Load Balancer when you need a high-performance transport layer (layer 4; TCP/UDP) load balancer, which integrates with many AWS services. Load balancers are a ubiquitous sight in a cloud environment. Datadog collects metrics and metadata from all three flavors of Elastic Load Balancers that AWS offers: Application, Classic, and Network Load Balancers. Amazon Web Services recently released new second generation load balancers: Application Load Balancer (ALB), and Network Load Balancer (NLB). Contrary to what D. Svanlund wrote earlier, the network load balancer does NOT appear to preserve the source IP address. HTTP(S) Load Balancing has less latency for complex assets than Network Load Balancing because fewer round trips are needed before a response completes.
