# ADVPERF01-BP03 Design for low latency with appropriate compute, storage, and network considerations 
<a name="advperf01-bp03"></a>

 Use features from AWS compute, storage, and network services that cater to low latency advertising workload needs. 

## Implementation guidance
<a name="implementation-guidance-36"></a>

 Consider the following guidance for compute, storage, and network: 

 **Compute** 
+  Use [compute-optimized](https://aws.amazon.com/ec2/instance-types/) instances. Use benchmarking based on parameters like CPU, memory, launch time, and burst performance to choose the appropriate instance type. 
+  Cluster your [EC2 instances](https://aws.amazon.com/ec2/) into [placement groups](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/placement-groups.html) for ad serving components for the lowest possible latency between instances. 

 **Storage** 
+  Implement instance-attached SSD [Amazon EBS](https://aws.amazon.com/ebs/) volumes for lowest latency storage. 
+  Implement provisioned IOPS SSDs if you have an IOPS-intensive workload. 
+  Implement [Amazon EFS](https://aws.amazon.com/efs/) for shared file storage with burst capability. 
+  Implement [Elasticache Redis](https://aws.amazon.com/elasticache/) or Memcached to cache frequently accessed data. 

 **Networking** 
+  Implement enhanced networking for higher I/O and packet per second performance. 
+  Implement [VPC endpoints](https://aws.amazon.com/vpc/) to access AWS services within the network.
