ELB is one of many AWS services that have a regional scope and can span across zones in a given region. Other services like Route 53 is global in scope, as shown below, and provides services to multiple Regions. A highly available application leveraging two Availability Zones.
ELB load balancers can span multiple AZs but cannot span multiple regions. That means that if you’d like to create a set of instances spanning both the US and Europe Regions you’d have to create two load balancers and have some sort of other means of distributing requests between the two load balancers.
Network Load Balancers can also load balance to IP-based targets that are deployed in an inter-region peered VPC. This support on Network Load Balancers is available in all AWS Regions.
A: Yes. Network Load Balancer currently supports 200 targets per Availability Zone. For example, if you are in two AZs, you can have up to 400 targets registered with Network Load Balancer.
A cross-region load balancer ensures a service is available globally across multiple Azure regions. If one region fails, the traffic is routed to the next closest healthy regional load balancer. In this tutorial, you learn how to: Create cross-region load balancer.
ELB is one of many AWS services that have a regional scope and can span across zones in a given region. Other services like Route 53 is global in scope, as shown below, and provides services to multiple Regions. A highly available application leveraging two Availability Zones.
Many cloud providers offer an option to span multiple regions. While Amazon Elastic Load Balancers (ELBs) are typically located at different application tiers, the underlying architecture allows you to spread them across multiple regions. As a result, these Elbs are not affected by failures in one region. This means that you can have one ELB in each region and a separate one in another region.
Classic ELB only routes requests to homogeneous servers, but ALB is capable of directing requests to a subgroup of backing servers, which is different than the default behavior. ALB creates a security group with up to 50 rules by default, but you can specify up to five security groups. In addition to this, you can also create multiple ELBSs and separate them. In the latter case, you must have at least one security group for each region you’d like to create.
In order to use an ELB in more than one region, you need to use two Availability Zones, or AZs. This way, your application will not be affected by a failure in any other region. Alternatively, you can use GeoIP techniques, or use DNS round-robin. However, it is advisable to use the DNS name provided by the ELB. Ultimately, you should make sure to use an ELB in two AZs, to make sure your application is always available.
