A: Elastic Load Balancing (ELB) supports four types of load balancers. Youneed to actively manage user profiles with one or more social or OpenID Connect identity providers from one central place. Elastic Load Balancing offers four types of load balancers, all featuring high availability, automatic scaling, and robust security support for your applications: Application Load Balancer, Network Load Balancer, Gateway Load Balancer, and Classic Load Balancer. Q: Is Gateway Load Balancer deployed per Region or per Availability Zone (AZ)? Application Load Balancer - AWS Lambda Events A:Yes, you can terminate HTTPS connection on the Application Load Balancer. A: You are charged for each hour or partial hour that an Application Load Balancer is running and the number of Load Balancer Capacity Units (LCU) used per hour. A: No, you are not charged for regional data transfer between Availability Zones when you enable cross-zone load balancing for your Classic Load Balancer. It exclusively mentions Network Load balancer can handle millions of requests but no mention about ALB. Q: What is the idle timeout supported by Network Load Balancer? The four dimensions measured are: You are charged only on the dimension with the highest usage. A: Yes. Youare managing multiple identity providers including OpenID Connect and want to create a single authentication rule in Application Load Balancer (ALB) that can use Amazon Cognito to federate your multiple identity providers. For Transport Layer Security (TLS) traffic, an NLCU contains: TCP and UDP traffic refers to the traffic destined for any TCP/UDP listener on your Network Load Balancer while TLS traffic refers to the traffic destined for any TLS listener on your Network Load Balancer. Upon sign-up, new AWS customers receive 750 hours per month shared between Classic and Application load balancers; 15 GB of data processing for Classic load balancers; and 15 LCUs for Application Load Balancers. You have configured 50 rules on the load balancer to route your client requests. For customers with a Japanese billing address, use of AWS is subject to Japanese Consumption Tax. A: You can either use AWS Certificate Manager to provision a SSL/TLS certificate or you can obtain the certificate from other sources by creating the certificate request, getting the certificate request signed by a CA, and then uploading the certificate using the AWS Identity and Access Management (IAM) service. Is there a faster algorithm for max(ctz(x), ctz(y))? Q:How does Gateway Load Balancer handle the failure of all virtual appliances within a single AZ? Gateway Load Balancer uses Gateway Load Balancer Endpoint (GWLBE),a new type of Amazon Virtual Private Cloud (VPC) endpoint powered by AWS PrivateLink technology that simplifies how applications can securely exchange traffic with GWLB across VPC boundaries. Q: Does Network Load Balancer support internal load balancers? A: No. If an application runs on targets distributed between a VPC and an on-premises location, you can add them to the same target group using their IP addresses. Q: How do I enable cross-zone load balancing in Gateway Load Balancer? This translates to 24,000 active connections, or 0.4 GLCUs (24,000 active connections per minute / 60,000 active connections per minute).
