Load balancer png3/9/2024 Under target groups, you are defining how the load balancer will attempt to reach your existing EC2 instances. If not, you will need to confirm what ports are being used for your external connections and add them to the list of Inbound Rules when creating a new group.įor this setup example, ensure that you at least have port 8043 added If you need to import one for the first time, you will need to create one from scratch Upload a certificate to ACM or IAM.įor this section, you also may already have some existing Security Groups defined when first setting up your instances. If someone has already created these certificates for you, then an IAM role with the correct permissions should be able to see previously uploaded certificates after selecting Choose a certificate from IAM. In your case you may have a different set of permissions on your AWS account and may be instructed to use ACM for storing and retrieving your certificates. For this example I will be importing one using IAM based on my permissions and preferences. This will allow the LB to look in the right place for each of the instances, so make sure none are left out here.įor this section, we will need an SSL certificate applied to the connection between our clients and the LB itself. ![]() If you’re not too sure about this, check the Instances page any look at the Availability Zones that are set for each of them Specify the Availability Zones that each of your EC2 instances reside in.So make sure you specify a meaningful name that you want your clients to see. The Name specified here will define the DNS hostname used to establish all sessions with our clients.Any attempts to have the LBs point to a non-https route / unsecure route will fail). (Note: It is important that the Ignition servers themselves have SSL configured. AWS ConfigurationĪssuming you already have properly configured EC2 instances to work with that already contain Ignition servers using SSL, we can navigate through your EC2 Dashboard and navigate to Load Balancing/Load Balancers to begin your configuration. An AWS Application Load Balancer (using the application layer) is an option provided by the Elastic Load Balancing feature and will allow you to efficiently distribute traffic of individual sessions/clients across your cloud instances. When multiple Perspective sessions and/or Vision clients need to be able to reach the Ignition server through this setup, you may need to ensure all of those connections are established and stay healthy without potentially interfering with one another. AWS Application Load BalancersĬloud-based, scaled-out architectures have become a very popular option for deploying larger enterprise systems. When a client requests from a server, the LB will instead decide based on multiple-defined http/https endpoints to establish a connection. So in terms of client requests making their way to servers, the LB only decides what destination IP is best for a connection without any additional context.Īpplication LBs operate at the seventh layer of the OSI model or the Application layer, meaning we focus on the interaction with a specific software application and its client requests via HTTP/HTTPS. ![]() ![]() Network LBs operate at the fourth layer of the OSI model or the Transport layer, meaning we focus on TCP/UDP connections that are established between specific source and destination IPs and Ports. The two main types of LBs will distribute traffic at either the Network or Application layer of communication. What are the main types of Load Balancers? Depending on the current client load of each server, the load balancer will decide which server is best to receive additional incoming client connections. With a LB, multiple servers can be utilized to handle the same client requests at a much larger scale. ![]() When large enterprise systems are expected to receive large amounts of clients daily, they may reach a point where a single server will not be enough to handle all requests. A Load Balancer (LB) provides an efficient way to distribute traffic and increase performance between servers and clients.
